    To compare six different parameters described in literature for estimation of pelvic tilt on an anteroposterior pelvic radiograph and to create a simple nomogram for tilt correction of prosthetic cup version in total hip arthroplasty. Simultaneous anteroposterior and lateral pelvic radiographs are taken routinely in our institution and were analyzed prospectively. The different parameters (including three distances and three ratios) were measured and compared to the actual pelvic tilt on the lateral radiograph using simple linear regression analysis. One hundred and four consecutive patients (41 men, 63 women with a mean age of 31.7 years, SD 9.2 years, range 15.7-59.1 years) were studied. The strongest correlation between pelvic tilt and one of the six parameters for both men and women was the distance between the upper border of the symphysis and the sacrococcygeal joint. The correlation coefficient was 0.68 for men (P<0.001) and 0.61 for women (P<0.001). Based on this linear correlation, a nomogram was created that enables fast, tilt-corrected cup version measurements in clinical routine use. This simple method for correcting variations in pelvic tilt on plain radiographs can potentially improve the radiologist's ability to diagnose and interpret malformations of the acetabulum (particularly acetabular retroversion and excessive acetabular overcoverage) and post-operative orientation of the prosthetic acetabulum.

    Background: A method to describe pelvic rotations between pairs of standard sequential pelvic anteroposterior radiographs based on a pelvic phantom is described in a former study. Purpose: To expand this method into clinical use based on clinical data. Material and Methods: Teardrop distances were measured on 262 pelvic radiographs from 46 patients in a clinical material using a computer program designed to perform measurements on digital radiographs. Anthropometric data recorded from 141 pelvises in an anatomical collection were employed in a computer program designed to simulate radiographs of virtual objects. Virtual rotations of the pelvises were carried out with 4653 virtual radiographs obtained. Virtual radiographic measures were analyzed. Results: A statistically significant difference of 8 mm between mean teardrop distance in females (120 mm) and males (112 mm) was found in the clinical material. A set of formulas describing the relations between differences of two rotation ratios and pelvic rotations were derived. Four simple regression analyses were carried out with the use of virtual measures. Adjusted teardrop distances were implemented. Conclusion: A clinical method to describe pelvic rotations using standard pelvic radiographs was developed.

    Screening pelvic radiographs to rule out pelvic fractures are routinely used for the initial evaluation of pediatric blunt trauma. Recently, the utility of routine pelvic radiographs in certain subsets of patients with blunt trauma has been questioned. There is a growing amount of evidence that shows the clinical exam is reliable enough to obviate the need for routine screening pelvic radiographs in children. To identify variables that help predict the presence or absence of pelvic fractures in pediatric blunt trauma. We conducted a retrospective study from January 2005 to January 2010 using the trauma registry at a level 1 pediatric trauma center. We analyzed all level 1 and level 2 trauma victims, evaluating history, exam and mechanism of injury for association with the presence or absence of a pelvic fracture. Of 553 level 1 and 2 trauma patients who presented during the study period, 504 were included in the study. Most of these children, 486/504 (96.4%), showed no evidence of a pelvic fracture while 18/504 (3.6%) had a pelvic fracture. No factors were found to be predictive of a pelvic fracture. However, we developed a pelvic fracture screening tool that accurately rules out the presence of a pelvic fracture P = 0.008, NPV 99, sensitivity 96, 8.98 (1.52-52.8). This screening tool combines eight high-risk clinical findings (pelvic tenderness, laceration, ecchymosis, abrasion, GCS <14, positive urinalysis, abdominal pain/tenderness, femur fracture) and five high-risk mechanisms of injury (unrestrained motor vehicle collision [MVC], MVC with ejection, MVC rollover, auto vs. pedestrian, auto vs. bicycle). Pelvic fractures in pediatric major blunt trauma can reliably be ruled out by using our pelvic trauma screening tool. Although no findings accurately identified the presence of a pelvic fracture, the screening tool accurately identified the absence of a fracture, suggesting that pelvic radiographs are not warranted in this subset of patients.

  4. Hip2Norm: an object-oriented cross-platform program for 3D analysis of hip joint morphology using 2D pelvic radiographs. (United States)

    Zheng, G; Tannast, M; Anderegg, C; Siebenrock, K A; Langlotz, F


    We developed an object-oriented cross-platform program to perform three-dimensional (3D) analysis of hip joint morphology using two-dimensional (2D) anteroposterior (AP) pelvic radiographs. Landmarks extracted from 2D AP pelvic radiographs and optionally an additional lateral pelvic X-ray were combined with a cone beam projection model to reconstruct 3D hip joints. Since individual pelvic orientation can vary considerably, a method for standardizing pelvic orientation was implemented to determine the absolute tilt/rotation. The evaluation of anatomically morphologic differences was achieved by reconstructing the projected acetabular rim and the measured hip parameters as if obtained in a standardized neutral orientation. The program had been successfully used to interactively objectify acetabular version in hips with femoro-acetabular impingement or developmental dysplasia. Hip(2)Norm is written in object-oriented programming language C++ using cross-platform software Qt (TrollTech, Oslo, Norway) for graphical user interface (GUI) and is transportable to any platform.

  5. The Risser sign for forensic age estimation in living individuals: a study of 643 pelvic radiographs. (United States)

    Wittschieber, Daniel; Schmeling, Andreas; Schmidt, Sven; Heindel, Walter; Pfeiffer, Heidi; Vieth, Volker


    Due to increasing international migratory movements, forensic age estimations of living individuals in criminal proceedings are gaining increasing significance for forensic physicians and radiologists involved in delivering expert opinions. The present study examines the suitability of the radiologically well-known Risser sign grading as a possible new criterion in forensic age diagnostics. For this purpose, anteroposterior pelvic radiographs of 643 patients aged between 10 and 30 years were retrospectively evaluated by means of two different Risser sign grading systems (US and French), each with 5 stages. The left and right sides of the pelvis were assessed separately. The data was analyzed with separation of the sexes. Reliable Risser sign determination was possible in 566 cases. In both sexes, stage 4 of both the US and the French grading systems was predominantly first noted at age 14 years. In the US grading system, stage 5 was also first achieved at age 14 years in the majority of both sexes. In the French grading system, females manifested stage 5 at a minimum of 16 years, whereas in males it was first observed at 17 years. As to the nature of iliac crest maturation, interesting deviations were observed at stages 1 and 5, raising doubts about Risser's ossification process. To conclude, both Risser sign grading systems are suitable for forensic age diagnostics, especially to determine whether the 14th year of life has been completed or not. The French Risser sign system additionally allows for statements as to the completion of the 16th year of age.

  6. Image quality in the anteroposterior cervical spine radiograph: Comparison between moving, stationary and non-grid techniques in a lamb neck

    Background: Cervical spine radiography is a commonly employed examination for degenerative disease and trauma in the cervical spine. Traditionally, the anteroposterior projection is undertaken with the use of an anti-scatter grid. Some practitioners appear to have rejected this practice in favour of a non-grid technique, possibly because of the dose saving it affords. It is necessary to determine if image quality in the cervical spine is significantly degraded and whether the omission of the grid is justified. Method: Using a slaughtered lamb neck as a model of the human neck triplicate radiographs were obtained using a non-grid, a stationary grid and a moving grid technique. Entrance surface dose and dose area product was measured for these techniques. Image quality in terms of contrast, sharpness and overall acceptability was evaluated by 9 independent and blinded observers. Results: A significant reduction in measured dose was observed when the non-grid technique was compared to stationary or moving grid techniques. A statistically significant reduction in image contrast, sharpness and acceptability was also seen in the non-grid compared to grid techniques. Conclusion: These results show evidence of significantly greater image quality in the presence of either a moving or stationary grid in the lamb model. As such they support the continued use of scatter rejection methods such as the anti-scatter grid in AP radiography of the human cervical spine, to optimise radiographic image quality in this critical structure.

    A change in the position of a prosthetic acetabular component between two different radiographic examinations indicates loosening, and may be observed as tilting or migration of the socket. To determine the apparent changes in socket position caused by improper positioning of the pelvis, a full-scale model of a pelvis with attached prosthetic sockets was examined radiographically in different positions. The projected alignment of the Charnley socket indicator wire against the inter-tuberosity line was markedly influenced by the positioning of the pelvis. An alternative way of measuring the alignment is to use the long axis of the projected ellipse of the outer circumferential groove in the socket polyethylene. The thus defined socket alignment was not influenced by the positioning of the pelvis within the investigated range. No apparent socket migration was recorded within the range of pelvic rotation and inclination studied. (orig.).

  8. Measuring acetabular cup orientation on antero-posterior radiographs of the hip after total hip arthroplasty with a vector arithmetic radiological method. Is it valid and verified for daily clinical practice?

Orthopedic Surgery; Zeman, F. [University Medical Center Regensburg, Bad Abbach/Regensburg (Germany). Center for Clinical Studies


    The aim of this prospective study is to validate a vector arithmetic method for measuring acetabular cup orientation after total hip arthroplasty (THA) and to verify the clinical practice. We measured cup anteversion and inclination of 123 patients after cementless primary THA twice by two examiners on AP pelvic radiographs with a vector arithmetic method and compared with a 3D-CT based reconstruction model within the same radiographic coronal plane. The mean difference between the radiographic and the 3D-CT measurements was -1.4 ±3.9 for inclination and 0.8 ±7.9 for anteversion with excellent correlation for inclination (r=0.81, p < 0.001) and moderate correlation for anteversion (r=0.65, p < 0.001). The intraclass correlation coefficient for measurements on radiographs ranged from 0.98 (95%-CI: 0.98; 0.99) for the first observer to 0.94 (95%-CI: 0.92; 0.96) for the second observer. The interrater reliability was 0.96 (95%-CI: 0.93; 0.98) for inclination and 0.93 (95%-CI: 0.85; 0.96) for anteversion. The largest errors in measurements were associated with an extraordinary pelvic tilt. In order to get a valuable measurement for measuring cup position after THA on pelvic radiographs by this vector arithmetic method, there is a need for a correct postoperative ap view, with special regards to the pelvic tilt for the future.

    Anđelković Zoran


    Full Text Available Background/Aim. Femoroacetabular impingement, a pathophysiological mechanism of small morphological changes of the hip leads to early arthritic changes. The aim of this study was to present a simple method for the quantification of femoral head and neck junction in patients with cam form of femoroacetabular impingement, in standardized anteroposterior and profile DUNN 90 radiograms of the hips. Methods. In standardized anteroposterior and profile DUNN 90 images of the hips we determined the angle of 2 alpha, defined by our own original method. We tested 141 hips in 81 patients without clinical signs of femoroacetabular impingement, and 153 hips in 76 patients with clinically clear signs of femoroacetabular impingement. Results. The value of the angle 2 alpha in anteroposterior hip radiograms was on average 113.7° for the patients with clinical symptoms of impingement, and 84.2° for the control group of patients (p ≤ 0.0001, and in DUNN 90 profile radiography of the hip, the value of 2 alpha angle in the patients group was 97.2°, and 74.6° in the control group (p ≤ 0.0001. The proposed method of determining the angle 2 alpha showed a high level sensitivity (97.8% and specificity (98.7 and positive predictive value (98.6%. It was false positive in only 1.3%, and false negative in 2.12% of patients. Conclusion. Using standardized anteroposterior and profile radiographs of the hips, and without determination of femoral neck axis in patients with femoroacetabular impingement with the cam effect at the junction of the femoral head and neck, we proposed the method of measuring joint abnormalities of femoral head and neck junction, very capable to predict the disease development in an asymptomatic risk group of patients and high sensitive in the diagnosis of the disease in the group of patients.

    Skeletal surveys for non-accidental trauma (NAT) include lateral spinal and pelvic views, which have a significant radiation dose. To determine whether pelvic and lateral spinal radiographs should routinely be performed during initial bone surveys for suspected NAT. The radiology database was queried for the period May 2005 to May 2011 using CPT codes for skeletal surveys for suspected NAT. Studies performed for skeletal dysplasia and follow-up surveys were excluded. Initial skeletal surveys were reviewed to identify fractures present, including those identified only on lateral spinal and/or pelvic radiographs. Clinical information and MR imaging was reviewed for the single patient with vertebral compression deformities. Of the 530 children, 223 (42.1%) had rib and extremity fractures suspicious for NAT. No fractures were identified solely on pelvic radiographs. Only one child (<0.2%) had vertebral compression deformities identified on a lateral spinal radiograph. This infant had rib and extremity fractures and was clinically paraplegic. MR imaging confirmed the vertebral body fractures. Since no fractures were identified solely on pelvic radiographs and on lateral spinal radiographs in children without evidence of NAT, nor in nearly all with evidence of NAT, inclusion of these views in the initial evaluation of children for suspected NAT may not be warranted.

    The purpose of this study was to review the MRI examinations of a large group of low-energy trauma patients in whom pelvic MRI had detected radiographically occult fractures, in order to characterize prevailing fracture patterns and determine how often co-existing proximal femoral and pelvic fractures were observed. All patients having pelvic MRI over 5 years were identified. Word-search software selected 269 MRI reports containing the term 'fracture'. Further scrutiny identified 168 with diagnosis of fracture. MRI request and imaging record review identified 102 low-energy trauma cases that had MRI for clinical suspicion of fracture despite normal radiographs. Sixty-six cases were excluded for the following reasons: no expressed clinical suspicion of occult fracture; history suggesting high-energy trauma; skeletal co-morbidity hindering acute fracture identification; interval more than 2 weeks between radiographs and MRI. The 102 study MRI examinations, which employed a limited two-sequence protocol, were reviewed. Any fracture that had not been appreciated on radiographs was recorded and characterized as femoral, pelvic, or co-existing femoral and pelvic fractures. The 102 study cases had a median age of 82 years. The median interval between pelvic radiographs and MRI was 3 days. MRI showed undiagnosed femoral fracture in 48/102 cases (47.1%), sacral fracture in 41/102 (40.2%), and pubic fracture in 55/102 (53.9%). In 11/102 cases (10.8%), MRI showed undiagnosed fractures of both proximal femur and pelvic ring (seven sacral, six pubic bone, two other site fractures). In 10/11 cases with co-existing femoral and pelvic fractures, the femoral fracture was incomplete. Limited pelvic MRI found a high prevalence of radiographically occult femoral and pelvic fractures in low-energy trauma patients, with clinical suspicion of fracture despite normal radiographs. Co-existing occult femoral and pelvic ring fractures were commonly observed, and in such cases, the

    Orientation of acetabular component, influenced by pelvic tilt, body position, and individual variations affects the outcome following total hip arthroplasty (THA). Currently available methods of evaluation are either imprecise or require advanced image processing. We analyzed intersubject and intrasubject variability of pelvic tilt, measured by sagittal sacral tilt (ST) and its relationship with acetabular component tilt (AT) by using a simple method based on standard radiographs. ST was measured on lateral radiographs of pelvis including lumbosacral spine obtained in supine, sitting, standing, and lateral decubitus position for 40 asymptomatic THA patients and compared to computed tomography (CT) data obtained in supine position. AT was measured on lateral radiographs (measured acetabular tilt: MAT) in each position and compared to measurement of AT on CT and an indirectly calculated AT (CAT). Mean ST changed from supine to sitting, standing, and lateral decubitus positions as follows: 26.5 {+-} 15.5 (range 4.6-73.4 ), 8.4{+-}6.2 (range 0.6-24.5 ), and 13.4{+-}8.4 (range 0.1-24.2 ; p<0.0001, p=0.002, p=0.006). The MAT on radiographs was not significantly different from the MAT measured on CT (p=0.002) and the CAT (p=0.06). There is a good correlation between change in ST and MAT in sagittal plane (r=0.93). Measurement of ST on radiographs is a simple and reliable method to track changes in pelvic tilt in different body positions. There is significant intersubject and intrasubject variation of ST and MAT with postural changes and it may explain causes of impingement or instability following THA, which could not be previously explained.

    A hyperdense line on the ilium that runs roughly parallel to the sacroiliac joint (we called it ''iliac hyperdense line sign'') was frequently observed on pelvic radiographs of patients with gluteal muscle contracture (GMC). A literature search revealed no description of this sign. To determine the relationship between the iliac hyperdense line sign and GMC and to explore how this sign is formed. Pelvic plain films of 103 cases of GMC and those of 200 control individuals were reviewed for the presence or absence of the iliac hyperdense line sign. Pelvic CT scans in 8 of 103 cases and 13 of 200 controls were analyzed with relation to the plain films. The iliac hyperdense line sign was visualized in 85 of 103 (82.5%) cases of GMC and none of the 200 controls. In the GMC group, pelvic CT scans showed a deformity of the posterior ilium. The lateral cortex of the posterior ilium took on a partly or completely anteroposterior course, while in the control group the course appeared as an oblique orientation from posteromedial to anterolateral. The iliac hyperdense line on pelvic plain film can be used as a radiographic sign to suggest a diagnosis of GMC. This sign might be a result of the long and persistent pulling effect of the contracted gluteus maximus muscle, which deforms the lateral cortex of the posterior ilium from an oblique course to an anteroposterior course tangential to the X-ray beam.

    Gonad shielding has been advocated to reduce radiation exposure in patients undergoing pelvic radiography. The aim of this study is to evaluate the frequency and accuracy of gonad shield placement in patients undergoing pelvic radiography. A retrospective study was performed on 1230 anteroposterior (AP) pelvic radiographs of 939 children under 16 years old. All the radiographs were reviewed to determine the frequency of gonad shielding and to evaluate whether gonad shields were correctly positioned when they are used. The gonad shield was present in 82 radiographs (30 girls and 52 boys) and was completely disregarded in 1148 radiographs. From 82 images which shield was present, the gonad shields adequately positioned in 28 radiographs (3 girls and 25 boys) and in the remaining 54 radiographs, the shield did not adequately protected the gonads due to incorrect placement of the shield. The inaccuracy placement and absence of gonad shields were more common in girls than boys (P-value < 0.05). More care should be taken to correctly positioning of the gonad shields in boys and its usage should be encouraged. However, the practice of ovarian shielding is not an effective way to reduce radiation exposure in girls undergoing pelvis radiography. (author)

  17. Role of computed tomography in the classification and management of pediatric pelvic fractures. (United States)

    Silber, J S; Flynn, J M; Katz, M A; Ganley, T J; Koffler, K M; Drummond, D S


    In adults, pelvic computed tomography (CT) scanning plays an important role in the treatment of pelvic fractures; however, the role of CT scanning in the management of pediatric pelvic fractures is unclear. The purpose of this study was to investigate the efficacy of CT scanning in the management of pelvic fractures in children. One hundred three consecutive patients were identified. All patients underwent anteroposterior plain radiographic evaluation; CT scans were performed in 62. Three orthopaedic surgeons independently reviewed the plain radiographs and determined fracture classification and management. Subsequently, each observer was shown corresponding CT scans and again determined classification and management. Interobserver agreement was calculated using Kappa statistics. After the addition of CT scans, the mean changes in classification were nine (15%) and in management two (3%). Plain radiographs alone reliably predicted the need and type of operative intervention. Kappa statistics demonstrated "excellent" agreement for classification and management without and with CT scans. We reliably determined fracture classification and management based on plain radiographs alone.

    Objective: To investigate the factors affecting the fixation, loosening and therapeutic effect of cementless acetabular prosthesis through following up the patients with total hip arthroplasty clinically and radiographically.Methods: From February 1998 to May 1999, 139 patients (148 hips) underwent total hip arthroplasty with cementless acetabular prosthesis in our department. In this study, the clinical therapeutic effect and the anteroposterior radiographs of the pelvis and anteroposterior and lateral radiographs of the hips of 109 patients (116 hips) made before operation, at 1 week, 3, 6, and 12 months after operation and annually thereafter were analyzed retrospectively. The clinical therapeutic effects were evaluated with Harris hip score. Radiographs were used to observe the position of prostheses and the bone changes around the implant, and to measure the wearing speed and direction of the acetabular cup. All evaluations were made by an independent examiner who did not participate in the operation. The patients were followed up for 5-6 years.Results: The mean Harris score was 44 points (range, 10-70 points) before operation, but it increased to 92.4 points (range, 80-100 points) at the latest review after operation, which was significantly higher than that before operation (P<0.05). No acetabular component was revised because of infection or aseptic loosening. And no acetabular component migrated. There was no revision of fixed acetabular component because of pelvic osteolysis secondary to polyethylene wear. The mean linear wear rate was 0.15 mm per year. All the acetabular prostheses were classified as stable on the radiographs.Conclusions: In terms of fixation, total hip arthroplasty with cementless acetabular components was successful. Although there is no aseptic loosening and a low incidence of osteolysis at the latest follow-up evaluation, polyethylene wear cannot be avoided and can lead to expansile osteolysis near the cups. This kind of osteolysis

    AIM To analyze planning total hip arthroplasty (THA) with an additional anteroposterior hip view may increases the accuracy of preoperative planning in THA. METHODS We conducted prospective digital planning in 100 consecutive patients: 50 of these procedures were planned using pelvic overview only (first group), and the other 50 procedures were planned using pelvic overview plus antero-posterior (a.p.) hip view (second group). The planning and the procedure of each patient were performed exclusively by the senior surgeon. Fifty procedures with retrospective analogues planning were used as the control group (group zero). After the procedure, the planning was compared with the eventually implanted components (cup and stem). For statistic analysis the χ2 test was used for nominal variables and the t test was used for a comparison of continuous variables. RESULTS Preoperative planning with an additional a.p. hip view (second group) significantly increased the exact component correlation when compared to pelvic overview only (first group) for both the acetabular cup and the femoral stem (76% cup and 66% stem vs 54% cup and 32% stem). When considering planning ± 1 size, the accuracy in the second group was 96% (48 of 50 patients) for the cup and 94% for the stem (47 of 50 patients). In the analogue control group (group zero), an exact correlation was observed in only 1/3 of the cases. CONCLUSION Digital THA planning performed by the operating surgeon and based on additional a.p. hip view significantly increases the correlation between preoperative planning and eventual implant sizes.

    To analyze intra and interobserver agreement of two radiographic methods for evaluation of posterolateral lumbar arthrodesis. Twenty patients undergoing instrumented posterolateral fusion were evaluated by anteroposterior and dynamic lateral radiographs in maximal flexion and extension. The images were evaluated initially by 6 orthopedic surgeons, and after 8 weeks, reassessed by 4 of them, totaling 400 radiographic measurements. Intra and interobserver reliability were analyzed using the Kappa coefficient and Landis and Koch criteria. Intra and interobserver agreement regarding anteroposterior radiographs were, respectively, 76 and 63%. On lateral views, these values were 78 and 84%, respectively. However, the Kappa analysis showed poor intra and interobserver agreement in most cases, regardless of the radiographic method used. There was poor intra and interobserver agreement in the evaluation of lumbosacral fusion by plain film in anteroposterior and dynamic lateral views, with no statistical superiority between the methods.

  6. CT of pelvic fractures

    Energy Technology Data Exchange (ETDEWEB)

    Falchi, Marco E-mail:; Rollandi, Gian Andrea


    Although magnetic resonance imaging has become the dominant modality for cross-sectional musculo-skeletal imaging, the widespread availability, speed, and versatility of computed tomography (CT) continue to make it a mainstay of emergency room (ER) diagnostic imaging. Pelvic ring and acetabular fractures occur as the result of significant trauma secondary to either a motor vehicle accident or a high-velocity fall. These injuries are correlated with significant morbidity and mortality, both from the complications of pelvic ring fractures and from commonly associated injuries. The most commonly used classification of pelvic and acetabular fractures has been based on conventional radiographs that are, in the majority of cases, sufficient to determine the type of injury. However, because of the complexity of pelvic and acetabular fractures, precise pathological anatomy is not easily demonstrated by routine radiographs and in many cases details of fractures are not visible. Moreover, the insufficient co-operation of the patient or the difficulty of maintaining special positions can be overcome by using computed tomography. Spiral computed tomography provides information regarding the extent of the fractures and is complementary to radiography for ascertaining the spatial arrangement of fracture fragments. Spiral computed tomography is an effective tool for understanding complex fracture patterns, particularly when combined with multi-planar reconstruction two-dimensional (MPR 2D) reformatted images or three-dimensional images (3D) images. Including these techniques of reconstruction in routine pelvic imaging protocols can change management in a significant number of cases. Subtle fractures, particularly those oriented in the axial plane, are better seen on MPR images or 3D volume-rendered images. Complex injuries can be better demonstrated with 3D volume-rendered images, and complicated spatial information about the relative positions of fracture fragments can be easily

    Pelvic actinomycosis is a rare chronic infection caused by bacteria of the family Actinomycetaceae. Prolonged use of an intrauterine contraceptive device (IUD) is a well known risk factor. We report six patients with pelvic actinomycosis, all of whom had an IUD inserted for over six years. Diagnostic problems necessitated a laparotomy in all patients. The pathohistological diagnosis was based on the characteristic microscopic image and specific staining. The patients were treated with penicillin and amoxycillin for several months.

  8. Conventional versus virtual radiographs of the injured pelvis and acetabulum

    Energy Technology Data Exchange (ETDEWEB)

    Bishop, Julius A.; Rao, Allison J.; Pouliot, Michael A.; Bellino, Michael [Stanford University School of Medicine, Department of Orthopaedic Surgery, Stanford, CA (United States); Beaulieu, Christopher [Stanford University School of Medicine, Department of Radiology, Stanford, CA (United States)


    Evaluation of the fractured pelvis or acetabulum requires both standard radiographic evaluation as well as computed tomography (CT) imaging. The standard anterior-posterior (AP), Judet, and inlet and outlet views can now be simulated using data acquired during CT, decreasing patient discomfort, radiation exposure, and cost to the healthcare system. The purpose of this study is to compare the image quality of conventional radiographic views of the traumatized pelvis to virtual radiographs created from pelvic CT scans. Five patients with acetabular fractures and ten patients with pelvic ring injuries were identified using the orthopedic trauma database at our institution. These fractures were evaluated with both conventional radiographs as well as virtual radiographs generated from a CT scan. A web-based survey was created to query overall image quality and visibility of relevant anatomic structures. This survey was then administered to members of the Orthopaedic Trauma Association (OTA). Ninety-seven surgeons completed the acetabular fracture survey and 87 completed the pelvic fracture survey. Overall image quality was judged to be statistically superior for the virtual as compared to conventional images for acetabular fractures (3.15 vs. 2.98, p = 0.02), as well as pelvic ring injuries (2.21 vs. 1.45, p = 0.0001). Visibility ratings for each anatomic landmark were statistically superior with virtual images as well. Virtual radiographs of pelvic and acetabular fractures offer superior image quality, improved comfort, decreased radiation exposure, and a more cost-effective alternative to conventional radiographs.

    Ioi, Hideki; Nakata, Shunsuke; Nakasima, Akihiko; Counts, Amy L


    The aims of this study were to determine Japanese cephalometric norms in the antero-posterior and vertical dimension, and to test the hypothesis that there are racial differences in cephalometric measurements between Japanese and Caucasian norms. Radiographs were obtained from 25 healthy Japanese males (aged 25.1 +/- 2.7 years) and 24 healthy Japanese females (aged 23.6 +/- 1.3 years). Inclusion criteria were an ANB angle between 2 and 5 degrees, a normal occlusion with minor or no crowding, all teeth present except third molars, no previous orthodontic treatment, and no prosthetic replacement of teeth. Two angular and five linear measurements were constructed for the skeletal hard tissue analysis, one angular and six linear measurements for the dental hard tissue analysis, and two angular and seven linear measurements for the soft tissue analysis. The mean and standard deviations for the hard and soft tissue measurements were determined for each gender. Unpaired t-tests were used to determine the mean differences for each cephalometric measurement between the Japanese and the Caucasians. In the antero-posterior dimension, the Japanese subjects had a significantly more retruded chin position (P vertical dimension, the Japanese had a significantly steeper mandibular plane (P cephalometric measurements might be helpful to formulate treatment plans for Japanese patients.

  16. On pelvic reference lines and the MR evaluation of genital prolapse: a proposal for standardization using the Pelvic Inclination Correction System. (United States)

    Betschart, C; Chen, L; Ashton-Miller, J A; Delancey, J O L


    Five midsagittal pelvic reference lines have been employed to quantify prolapse using MRI. However, the lack of standardization makes study results difficult to compare. Using MRI scans from 149 women, we demonstrate how use of existing reference lines can systematically affect measurements in three distinct ways: in oblique line systems, distances measured to the reference line vary with antero-posterior location; soft issue-based reference lines can underestimate organ movement relative to the pelvic bones; and systems defined relative to the MR scanner are affected by intra- and interindividual differences in the pelvic inclination angle at rest and strain. Thus, we propose a standardized approach called the Pelvic Inclination Correction System (PICS). Based on bony structures and the body axis, the PICS system corrects for variation in pelvic inclination, at rest of straining, and allows for the standardized measurement of organ displacement in the direction of prolapse.

  17. Imaging Evaluation of Superior Labral Anteroposterior (SLAP) Tears. (United States)

    Grubin, Jeremy; Maderazo, Alex; Fitzpatrick, Darren


    Superior labral anteroposterior (SLAP) tears are common injuries that are best evaluated with magnetic resonance arthrography (MRA), as it provides the most detailed evaluation of the bicipital labral complex. Given the variety and complexity of SLAP tears, distention of the joint with intra-articular dilute gadolinium contrast properly separates the intra-articular biceps tendon, superior labrum, glenoid cartilage and glenohumeral ligaments to optimize assessment of these structures. This allows for increased diagnostic confidence of the interpreting radiologist and provides a better road map for the surgeon prior to arthroscopy. Indirect MRA and high-field magnetic resonance imaging are sensitive and specific alternative modalities if MRA cannot be performed.

  20. Pelvic congestion syndrome masquerading as osteoarthritis of the hip

    Directory of Open Access Journals (Sweden)

    Scott J Dos Santos


    Full Text Available Objectives: Pelvic congestion syndrome (PCS is associated with pelvic vein reflux (PVR, occasionally secondary to venous compression. Its symptoms, usually intra-pelvic, are alleviated following the abolition of this reflux by pelvic vein embolisation (PVE. The objective of this report is to present two cases of left hip pain, erroneously diagnosed as osteoarthritis, which disappeared after successful PVE and abolition of PVR. Methods: Two females presented with lower limb varicose veins, and also had a history of left-sided hip pain. Both had previously been investigated for the hip pain and diagnosed as osteoarthritis despite minimal arthritic changes on pelvic X-rays. During investigation for lower limb varicose veins, both showed a pelvic origin for their leg veins and hence underwent transvaginal duplex ultrasound. This revealed PVR, and PVE was planned in both patients. Results: Both patients underwent PVE and reported ‘miraculous’ resolution of left hip pain and also PCS symptoms including pelvic pain, irritable bowel issues and the disappearance of pelvic dragging, with almost immediate disappearance of vulval and vaginal varicosities. One patient also noted reduced clitoral sensitivity. Conclusion: Manifestations of PCS may vary in terms of intra- or extra-pelvic signs. PCS and PVR should be considered in the differential diagnosis of patients with arthritic symptoms in the hip without evident radiographic evidence.

  1. Triple pelvic osteotomy in Legg-Calve-Perthes disease using a single anterolateral incision: a 4-year review.

    LENUS (Irish Health Repository)

    Conroy, Eimear


    Femoral head incongruency at skeletal maturity is associated with the development of osteoarthritis in early adulthood. Containment of the femoral head provides a larger surface area for remodelling of the collapsed femoral head and the development of spherical congruency. Triple pelvic osteotomy has a role to play in Legg-Calve-Perthes\\' disease by improving femoral head containment and preventing subluxation. This is traditionally a two-incision approach with significant associated morbidity. In our unit we perform triple osteotomies through a single anterolateral incision. To retrospectively review the clinical and radiographic outcome of children who had triple osteotomies performed through a single incision over a 4-year period. In our unit from 2003 to 2006 we performed eight triple osteotomies through a single incision in children aged between 6 and 12 years with Legg-Calve-Perthes\\' disease. The procedure was performed through a single anterolateral incision made beneath the middle of the iliac crest and carried forward according to Salter\\'s osteotomy. Image intensification was used to confirm iliac, pubic and ischial cuts. After performing a standard Salter\\'s osteotomy the acetabular fragment was free to rotate anteriorly and laterally. None of the children were casted and all were allowed immediate mobilization nonweight bearing with crutches for 6 weeks. Clinical results and hip function were measured preoperatively and postoperatively using the modified Harris hip score. The average length of hospital stay was 4.7 days. None of the children had a nonunion. The centre edge angle of Wiberg was measured on all preoperative and postoperative anteroposterior pelvic radiographs. In all our patients there was an improvement in the centre edge angle of Wiberg and in the modified Harris hip score. The preoperative modified Harris hip scores ranged from 38 to 60 and postoperatively ranged from 77 to 92. The preoperative centre edge angle of Wiberg ranged

  4. HipMatch: an object-oriented cross-platform program for accurate determination of cup orientation using 2D-3D registration of single standard X-ray radiograph and a CT volume. (United States)

    Zheng, Guoyan; Zhang, Xuan; Steppacher, Simon D; Murphy, Stephen B; Siebenrock, Klaus A; Tannast, Moritz


    The widely used procedure of evaluation of cup orientation following total hip arthroplasty using single standard anteroposterior (AP) radiograph is known inaccurate, largely due to the wide variability in individual pelvic orientation relative to X-ray plate. 2D-3D image registration methods have been introduced for an accurate determination of the post-operative cup alignment with respect to an anatomical reference extracted from the CT data. Although encouraging results have been reported, their extensive usage in clinical routine is still limited. This may be explained by their requirement of a CAD model of the prosthesis, which is often difficult to be organized from the manufacturer due to the proprietary issue, and by their requirement of either multiple radiographs or a radiograph-specific calibration, both of which are not available for most retrospective studies. To address these issues, we developed and validated an object-oriented cross-platform program called "HipMatch" where a hybrid 2D-3D registration scheme combining an iterative landmark-to-ray registration with a 2D-3D intensity-based registration was implemented to estimate a rigid transformation between a pre-operative CT volume and the post-operative X-ray radiograph for a precise estimation of cup alignment. No CAD model of the prosthesis is required. Quantitative and qualitative results evaluated on cadaveric and clinical datasets are given, which indicate the robustness and the accuracy of the program. HipMatch is written in object-oriented programming language C++ using cross-platform software Qt (TrollTech, Oslo, Norway), VTK, and Coin3D and is transportable to any platform.

  6. Static rearfoot alignment: a comparison of clinical and radiographic measures. (United States)

    Lamm, Bradley M; Mendicino, Robert W; Catanzariti, Alan R; Hillstrom, Howard J


    Foot structure is typically evaluated using static clinical and radiographic measures. To date, the literature is devoid of a correlation between rearfoot frontal plane radiographic parameters and clinical measures of alignment. In a repeated-measures study comparing radiographic and clinical rearfoot alignment in 24 healthy subjects, radiographic angular measurements were made from standard weightbearing anteroposterior, lateral, long leg calcaneal axial, and rearfoot alignment views. Clinical measurements were made using a jig and scanner to assess the malleolar valgus index and a goniometer to evaluate the resting and neutral calcaneal stance positions. There was a significant correlation between frontal plane radiographic angles (long leg calcaneal axial and rearfoot alignment views) (r = 0.814). Similarly, there was a significant correlation between clinical measures (resting calcaneal stance position and malleolar valgus index) (r = 0.714). A multivariate stepwise regression showed that resting calcaneal stance position can be accurately predicted from 3 of the 15 clinical and radiographic measurements collected: malleolar valgus index, rearfoot alignment view, and long leg calcaneal axial view (r = 0.829). In summary, a commonly used clinical measure of static rearfoot alignment, resting calcaneal stance position, was correlated closely with the malleolar valgus index and both frontal plane radiographic parameters.

    Yaman, İsmail; İnceboz, Ümit; İnceboz, Tonay; Keyik, Bahar; Uzgören, Engin


    Cystic echinococcosis caused by Echinococcus granulosus is still an important health problem in endemic areas. Cystic echinococcosis may involve different organs or areas with the most common sites being the liver and the lungs. Pelvic involvement has previously been reported and was mainly accepted as secondary to cystic echinococcosis in other organs, isolated pelvic involvement is very rare. In this case report, we aimed to present the case with pelvic cystic mass that was finally diagnosed with isolated pelvic cystic echinococcosis in and after the operation, and we would like to draw attention to include "cystic echinococcosis" in the differential diagnosis of pelvic masses.

  8. Anteroposterior jaw position in persons with skeletal class I

    Vučinić Predrag


    Full Text Available Introduction Many authors point out that there are great differences in anthropometric studies due to racial, ethnic and population morphological characteristics. Facial type is a decisive factor when planning and setting objectives, as well as when choosing the mode of orthodontic treatment. The aim of this study was to determine the morphological characteristics of antero-posterior position of maxilla and mandible and determine the most prevalent facial type in children living in Vojvodina. Material and methods Sixty cephalograms of both males and females, with skeletal class I and harmonious facial profile, were digitized and the following skeletal measurements were calculated: SNA, SNB and ANB angles. For comparative analysis, characteristics of craniofacial complex of the tested population were compared to Bolton standards from the Broadbent-Bolton longitudinal growth study. Results A statistically significant difference of both maxillary and mandibular prognathism were present when compared to Bolton standards. This indicates more retrognathic viscerocranial structures, and more posteriorly divergent profiles (SNA=81.7o; SNB=78.23o. Conclusion Differences identified in craniofacial parameters in relation to Bolton standards show that one should carefully consider the risk of altering facial esthetics of patients from Vojvodina with extraction treatment. Whenever possible, give priority to early non-extraction treatment, in order to reach the best possible end-result within the given facial type, preserving facial esthetics.

As for the anatomy of the pelvic organs consists of bones, muscles, and nerves. The presence of damage to the pelvic connective tissue and visceral attachment pelvic organs the cause occurs. The symptoms that appear in patients POP not specific to distinguish prolapse of some compartments but can reflect the degree of prolapse as a whole. Physical examination focused on pelvic examination, beginning with inspection on the vulva and vagina to identify the presence of erosion, ulceration, or other lesions. As for the existing therapy options include observation, non-operative management, and operative management.

  10. Transcriptional components of anteroposterior positional information during zebrafish fin regeneration. (United States)

    Nachtrab, Gregory; Kikuchi, Kazu; Tornini, Valerie A; Poss, Kenneth D


    Many fish and salamander species regenerate amputated fins or limbs, restoring the size and shape of the original appendage. Regeneration requires that spared cells retain or recall information encoding pattern, a phenomenon termed positional memory. Few factors have been implicated in positional memory during vertebrate appendage regeneration. Here, we investigated potential regulators of anteroposterior (AP) pattern during fin regeneration in adult zebrafish. Sequence-based profiling from tissues along the AP axis of uninjured pectoral fins identified many genes with region-specific expression, several of which encoded transcription factors with known AP-specific expression or function in developing embryonic pectoral appendages. Transgenic reporter strains revealed that regulatory sequences of the transcription factor gene alx4a activated expression in fibroblasts and osteoblasts within anterior fin rays, whereas hand2 regulatory sequences activated expression in these same cell types within posterior rays. Transgenic overexpression of hand2 in all pectoral fin rays did not affect formation of the proliferative regeneration blastema, yet modified the lengths and widths of regenerating bones. Hand2 influenced the character of regenerated rays in part by elevation of the vitamin D-inactivating enzyme encoded by cyp24a1, contributing to region-specific regulation of bone metabolism. Systemic administration of vitamin D during regeneration partially rescued bone defects resulting from hand2 overexpression. Thus, bone-forming cells in a regenerating appendage maintain expression throughout life of transcription factor genes that can influence AP pattern, and differ across the AP axis in their expression signatures of these and other genes. These findings have implications for mechanisms of positional memory in vertebrate tissues.

    Full Text Available ABSTRACT Objectives: To demonstrate the recovery of lumbar sagittal pelvic alignment and sagittal pelvic balance after surgical reduction of lumbar spondylolisthesis and establish the benefits of the surgery for reduction and fixation of the lumbar spondylolisthesis with 360o circumferential arthrodesis for 2 surgical approaches by clinical and functional evaluation. Method: Eight patients with lumbar spondylolisthesis treated with surgical reduction and fixation of listhesis and segmental circumferential fusion with two surgical approaches were reviewed. They were evaluated before and after treatment with Oswestry, Visual Analogue for pain and Odom scales, performing radiographic measurement of lumbar sagittal alignment and pelvic sagittal balance with the technique of pelvic radius. Results: Oswestry scales and EVA reported improvement of symptoms after treatment in 8 cases; the Odom scale had six outstanding cases reported. The lumbar sagittal alignment presented a lumbosacral lordosis angle and a lumbopelvic lordosis angle reduced in 4 cases and increased in 4 other cases; pelvic sagittal balance increased the pelvic angle in 4 cases and decreased in 3 cases and the sacral translation of the hip axis to the promontory increased in 6 cases. Conclusion: The surgical procedure evaluated proved to be useful by modifying the lumbar sagittal alignment and the pelvic balance, besides reducing the symptoms, enabling the patient to have mobility and movement and the consequent satisfaction with the surgery.

    Full Text Available OBJECTIVE: To establish the radiographic distances from posterior cruciate ligament (PCL tibial insertions centers to the lateral and medial tibial cortex in the anteroposterior view, and from these centers to the PCL facet most proximal point on the lateral view, in order to guide anatomical tunnels drilling in PCL reconstruction and for tunnel positioning postoperative analysis.STUDY DESIGN: Controlled laboratory study.METHODS: Twenty cadaver knees were evaluated. The PCL's bundles tibial insertions were identified and marked out using metal tags, and the knees were radiographed. On these radiographs, the bundles insertion sites center location relative to the tibial mediolateral measure, and the distances from the most proximal PCL facet point to the bundle's insertion were determined. All measures were calculated using the ImageJ software.RESULTS: On the anteroposterior radiographs, the mean distance from the anterolateral (AL bundle insertion center to the medial tibial edge was 40.68 ± 4.10 mm; the mean distance from the posteromedial (PM bundle insertion center to the medial tibial edge was 38.74 ± 4.40 mm. On the lateral radiographs, the mean distances from the PCL facet most proximal point to AL and PM bundles insertion centers were 5.49 ± 1.29 mm and 10.53 ± 2.17 mm respectively.CONCLUSIONS: It was possible to establish a radiographic pattern for PCL tibial bundles insertions, which may be useful for intraoperative tunnels locations control and for postoperative tunnels positions analysis.

    Full Text Available Background: Gonad shielding has been recommended during pelvic x-rays since the 1950s. The popular method of gonad shielding is placement a lead shield in the midline of the pelvis. The aim of this study was to evaluate the prevalence and utility of gonad shielding in pediatrics undergoing pelvic x-rays.Materials and MethodsFollowing study approval, we retrospectively retrieved data from the digital image library of ten radiology depertments of Khuzestan provience-Iran to identify pediatric patients who underwent pelvic x-ray (anteriorposterior [AP] view. All the images were reviewed for the probable evidence of gonad shield. If there was evidence of shielding, the accuracy positioning of the shield was also investigated by a single assistant radiologist.ResultsIn all 1745 pelvic x-rays (942 girls and 803 boys were identified of which the shield was present in 51 (5.41% radiographs of girls and 132 (16.43% radiographs of boys. When a shield was present; the shields has adequate positioning only in 8 (15.68% radiographs in girls and 59 radiographs in boys. Inaccurate placement and absence of gonad shields were more common in girls than the boys. Due to the shield has concealed the anatomical criteria of the pelvis, retakes of the examination was required in 11 (21.56% radiographs of girls and 14 (10.6% radiographs of boys.ConclusionThe current methods of gonad shielding in girls pelvic x-ray was not effective nor is justifiable. We  no longer advocate of gonad shielding during girls pelvic x-ray. However in boys it is controversial and depends on the skill and effort of radiographers.

    The development of reconstructive surgery of the lower limbs aimed at multilevel correction demands a precise knowledge of the physiological variations in general radiological parameters of the lower limbs in children of various age groups. It is crucial in systemic skeletal diseases, when deformities affect limbs and the surgeon does not have an intact limb as a reference. The aim of this retrospective study was to establish the normal radiological values of lower limb parameters used in the surgical correction of deformities in children of various age groups. Teleradiographs of the lower limbs taken in children with unilateral congenital or posttraumatic deformity were retrospectively reviewed. Weight-bearing full-length anteroposterior radiographs of the entire lower extremities were taken in a standing position. The study involved 215 extremities of 208 children (93 girls and 115 boys); the ages ranged from 2 years 1 month to 15 years 11 months old. Key variables included the anatomic medial proximal femoral angle (aMPFA), anatomic lateral distal femoral angle (aLDFA), anatomic medial proximal tibial angle (aMPTA), anatomic lateral distal tibial angle (aLDTA), mechanical axis deviation (MAD), the angle formed by the femoral anatomical axis and the mechanical axis of the lower limb. The means and dynamics of variations, standard deviations (SD) and 95 % confidence intervals of each parameter were calculated for each age and gender group. Simple regression analysis was performed to determine the relationship between the patient's age and the magnitude of aMPFA, aLDFA, aMPTA and aLDTA. Simple regression analysis showed a significant inverse correlation between patient age and the magnitude of aMPFA: the correlation coefficient was -0.77. A statistically significant inverse correlation between the MAD and the angle between the anatomic femoral axis and mechanical limb axis was found: the correlation coefficient was -0.53. In general, the received values were

  18. Comparison of Natural Head Position in Different Anteroposterior Malocclusions (United States)

    Hedayati, Zohreh; Paknahad, Maryam; Zorriasatine, Farbod


    Objective: The facial esthetics after orthodontic treatment and orthognathic surgery may be affected by the patient’s natural head position. The purpose of this study was to evaluate the natural head position for the three skeletal classes of malocclusion. Materials and Methods: Our sample consisted of 102 lateral cephalometric radiographs of patients aged 15 to 18 years; class I (n=32), class II (n=40) and class III (n=30). Nine landmarks of the craniofacial skeleton and three landmarks of the cervical vertebrae were determined. Variables consisted of two angles for cervical posture (OPT/Hor and CVT/Hor), three angles for craniofacial posture (SN/Ver, PNS-ANS/Ver, and ML/Ver ) and five for craniofacial angulation (SN/OPT, SN/CVT, PNS-ANS/OPT, PNS-ANS/CVT, ML/CVT). The data were analyzed statistically using ANOVA and post hoc tests. Results: PNS-ANS/Ver and SN/Ver differed significantly (p<0.05) among the three groups. There were no significant differences between class I and class II malocclusions for the indicator angles of cranial posture except for ML/Ver. The SN/CVT was significantly different for class I compared to class III patients. A head posture camouflaging the underlying skeletal class III was observed in our population. Conclusion: A more forward head posture was observed in skeletal class III participants compared to skeletal class I and II and that class III patients tended to incline their head more ventral compared to class I participants. These findings may have implications for the amount of jaw movements during surgery particularly in patients with a class III malocclusion. PMID:25512747

  20. Myofascial pelvic pain. (United States)

    Kotarinos, Rhonda


    Myofascial pelvic pain is fraught with many unknowns. Is it the organs of the pelvis, is it the muscles of the pelvis, or is the origin of the pelvic pain from an extrapelvic muscle? Is there a single source or multiple? In this state of confusion what is the best way to manage the many symptoms that can be associated with myofascial pelvic pain. This article reviews current studies that attempt to answer some of these questions. More questions seem to develop as each study presents its findings.

  1. Characterization of radiographic features of consecutive lumbar spondylolisthesis (United States)

    Sun, Yapeng; Wang, Hui; Yang, Dalong; Zhang, Nan; Yang, Sidong; Zhang, Wei; Ding, Wenyuan


    Abstract Radiographic features of consecutive lumbar spondylolisthesis were retrospectively analyzed in a total of 17 patients treated for this condition at the Third Hospital of Hebei Medical University from June 2005 to March 2012. To investigate the radiographic features, pelvic compensatory mechanisms, and possible underlying etiologies of consecutive lumbar spondylolisthesis. To the best of our knowledge, there is no previous report concerning the characteristics of consecutive lumbar spondylolisthesis. The Taillard index and the lumbar lordosis (LL), pelvic incidence (PI), sacrum slope (SS), and pelvic tilt (PT) were determined on lateral X-ray images, and the angular displacement was analyzed on flexion–extension X-ray images. Correlation between LL and various pelvic parameters and correlation between Taillard index and angular displacement were assessed by Pearson correlation analysis. A total of 20 cases of isthmic spondylolisthesis and 14 of degenerative spondylolisthesis were retrospectively studied in 17 patients. The Taillard index and the angular displacement in the lower vertebrae were both larger than those in the upper vertebrae. Statistical analysis revealed that LL was correlated with PI and PT, whereas PI was correlated with PT and SS. However, no correlation was identified between Taillard index and angular displacement. In consecutive lumbar spondylolisthesis, the degree of vertebral slip and the angular displacement of the lower vertebrae were both greater than those of the upper vertebrae, indicating that the compensatory mechanism of the pelvis plays an important role in maintaining sagittal balance.

  3. Chronic pelvic floor dysfunction. (United States)

    Hartmann, Dee; Sarton, Julie


    The successful treatment of women with vestibulodynia and its associated chronic pelvic floor dysfunctions requires interventions that address a broad field of possible pain contributors. Pelvic floor muscle hypertonicity was implicated in the mid-1990s as a trigger of major chronic vulvar pain. Painful bladder syndrome, irritable bowel syndrome, fibromyalgia, and temporomandibular jaw disorder are known common comorbidities that can cause a host of associated muscular, visceral, bony, and fascial dysfunctions. It appears that normalizing all of those disorders plays a pivotal role in reducing complaints of chronic vulvar pain and sexual dysfunction. Though the studies have yet to prove a specific protocol, physical therapists trained in pelvic dysfunction are reporting success with restoring tissue normalcy and reducing vulvar and sexual pain. A review of pelvic anatomy and common findings are presented along with suggested physical therapy management.

    Full Text Available Single system orthotopic ureteroceles often present in adulthood are associated with characteristic radiographic findings. We present the case of a 54 year old woman with 8 months of urgency/frequency and pelvic pain that has the cystoscopic appearance of a bladder tumor. Cystoscopic images, radiographs and intraoperative photos demonstrate the work-up, evaluation, and treatment of this unique single system orthotopic ureterocele containing a calculus. This patient demonstrates the need for cystoscopy accompanied by upper tract imaging in patients with new onset pelvic pain, urgency/frequency, and frequent urinary tract infections.

    Advances in MR imaging technologies, as well as the widening of their availability, boosted their use in the diagnosis of spinal disorders and in the preoperative planning of spine surgeries. However, the most consolidated approach to the assessment of adult patients with spinal disorders is based on the analysis of full standing radiographs (posteroanterior and laterolateral views). In this article, the radiographic spinal and pelvic parameters, which have relevance in the clinical management of adults with spinal disorders, are summarized.

  8. The arm posture in children with unilateral Cerebral Palsy is mainly related to antero-posterior gait instability. (United States)

    Meyns, Pieter; Duysens, Jacques; Desloovere, Kaat


    In this observational case-control study we aimed to determine whether altered arm postures in children with unilateral CP (uniCP) are related to gait instability in a specific direction. Antero-posterior and medio-lateral Foot Placement Estimator instability measures and arm posture measures (vertical and antero-posterior hand position, sagittal and frontal upper arm elevation angle) were determined in eleven uniCP (7 years-10 months) and twenty-four typically developing children (9 years-6 months) at two walking speeds. Spearman-rank correlation analyses were made to examine the relationship between antero-posterior and medio-lateral arm posture and gait instability. Arm posture in both planes was related to antero-posterior instability (e.g. sagittal and frontal upper arm elevation angle correlated moderately with antero-posterior instability; R=0.41, pposture in uniCP may be a compensation to reduce antero-posterior gait instability.

  9. [Pelvic floor and pregnancy]. (United States)

    Fritel, X


    Congenital factor, obesity, aging, pregnancy and childbirth are the main risk factors for female pelvic floor disorders (urinary incontinence, anal incontinence, pelvic organ prolapse, dyspareunia). Vaginal delivery may cause injury to the pudendal nerve, the anal sphincter, or the anal sphincter. However the link between these injuries and pelvic floor symptoms is not always determined and we still ignore what might be the ways of prevention. Of the many obstetrical methods proposed to prevent postpartum symptoms, episiotomy, delivery in vertical position, delayed pushing, perineal massage, warm pack, pelvic floor rehabilitation, results are disappointing or limited. Caesarean section is followed by less postnatal urinary incontinence than vaginal childbirth. However this difference tends to disappear with time and following childbirth. Limit the number of instrumental extractions and prefer the vacuum to forceps could reduce pelvic floor disorders after childbirth. Ultrasound examination of the anal sphincter after a second-degree perineal tear is useful to detect and repair infra-clinic anal sphincter lesions. Scientific data is insufficient to justify an elective cesarean section in order to avoid pelvic floor symptoms in a woman without previous disorders.

  10. Pelvic Organ Prolapse: New Concepts in Pelvic Floor Anatomy. (United States)

    Maldonado, Pedro A; Wai, Clifford Y


    As the field of reconstructive pelvic surgery continues to evolve, with descriptions of new procedures to repair pelvic organ prolapse, it remains imperative to maintain a functional understanding of pelvic floor anatomy and support. The goal of this review was to provide a focused, conceptual approach to differentiating anatomic defects contributing to prolapse in the various compartments of the vagina. Rather than provide exhaustive descriptions of pelvic floor anatomy, basic pelvic floor anatomy is reviewed, new and historical concepts of pelvic floor support are discussed, and relevance to the surgical management of specific anatomic defects is addressed.

  11. Comparative radiographic analysis on the anatomical axis in knee osteoarthritis cases: inter and intraobserver evaluation

    Luiz Felipe Matos


    Full Text Available OBJECTIVE: To make a comparative inter and intraobserver analysis on measurements of the anatomical axis between panoramic radiographs of the lower limbs in anteroposterior (AP view with bipedal weight-bearing, on short film.METHODS: An accuracy study comparing radiographic measurements on 47 knees of patients attending the knee surgery outpatient clinic due to osteoarthritis. The radiographic evaluation used was as standardized for the total knee arthroplasty program, including panoramic AP views of the lower limbs and short radiographs of the knees in AP and lateral views, all with bipedal weight-bearing. Following this, the anatomical axis of the lower limbs or the femorotibial angle was measured by five independent examiners on the panoramic and short AP radiographs; three of the examiners were considered to be more experienced and two, less experienced. All the measurements were made again by the same examiners after an interval of not less than 15 days. The statistical analysis was performed using the intraclass correlation coefficient, in order to evaluate the inter and intraobserver concordance of the anatomical axis measurements.RESULTS: From the statistical analysis, it was observed that there was strongly significant concordance between the anatomical axis measurements on the panoramic and short radiographs, for all the five examiners and for both measurements.CONCLUSIONS: Under the conditions studied, short radiographs were equivalent to panoramic radiographs for evaluating the anatomical axis of the lower limbs in patients with advanced osteoarthritis. The measurements used also showed high rates of inter and intraobserver concordance and reproducibility.

    The purpose of this study is to compare radiographic techniques for the diagnostic accuracy in the detection of osteophytes of the mandibular condyle. A series of bone chips were placed at four locations on the condylar head of a dried human skull. Eight radiographic techniques such as panoramic, transcranial, infracranial, transorbital, reverse-Towne's, submentovertex, multidirectional tomographic and computed tomographic techniques were compared. Three oral radiologists were asked to rate the lesions by four stage score. The statistical analysis was performed by ANOVA test. For the detection of lateral osteophyte, transcranial, infracranial, transorbital and reverse-Towne's views showed superiority. Also, transcranial and infracranial views showed superiority for medial osteophyte. While for the detection of superior and anterior osteophyte, panoramic, transcranial, infracranial, transorbital views showed superiority. Lateral tomograph showed superiority for the detection of superior and anterior osteophyte, but it showed inferiority for lateral and medial osteophte. And antero-posterior tomograph showed superiority for the detection of all osteophytes. Axial computed tomograph showed superiority for the detection of all osteophytes, and coronal computed tomograph showed superiority for lateral, medial and superior osteophytes. While reconstructed sagittal computed tomograph showed relatively superiority for the detection of anterior and superior osteophytes. The conventional radiographs can be used for the detection of bony changes of the mandibular condyle, and tomograph or computed tomograph can be used additionally when it is difficult to detect bony changes on conventional radiographs.

  13. Do we really need radiographic assessment for the diagnosis of non-specific heel pain (calcaneal apophysitis) in children?

    Kose, Ozkan [Diyarbakir Education and Research Hospital, Orthopaedics and Traumatology Clinic, Diyarbakir (Turkey); Diclekent Bulvari, Ataslar Serhat Evleri, Diyarbakir (Turkey)


    Non-specific heel pain (calcaneal apophysitis) is a common disorder, particularly in physically active growing children. Foot radiographs are usually obtained as part of the clinical evaluation in routine orthopaedic practice. However, there is still controversy about the specific findings on radiographs, and it is unclear what information is present on radiographs that may alter the diagnosis and management. The purpose of this study was to review a consecutive series of patients with the diagnosis of calcaneal apophysitis to assess the yield of routine radiographs of the foot. A prospective study was performed on 61 consecutive patients with a diagnosis of calcaneal apophysitis in a single-surgeon practice. Standard anteroposterior and lateral weight-bearing foot radiographs were obtained for each patient. Seventy-one sets of foot radiographs were reviewed to determine whether radiographs had an impact on diagnosis and management. Patients with antecedent trauma, penetrating injury, foot deformity, achilles tendonitis, bursitis and infections were excluded from the study. Seventy foot radiographs were considered to be normal. The radiographs changed the diagnosis in only one patient, in whom a simple bone cyst of the calcaneous was seen. Calcaneal apophysitis is a self-limiting disease, and patients can be treated conservatively. Neither the sclerosis nor the fragmentation of the apophysis could be used to establish the diagnosis of calcaneal apophysitis. Therefore, obtaining radiographs as an initial step in their evaluation does not seem to be justified. (orig.)

    YAN Gui-sen; YANG Zheng; LU Ming; ZHANG Jian-li; ZHU Zheng-hua; GUO Yuan


    Background Idiopathic flexible flatfoot in children most frequently improves with age and remains asymptomatic.It is a physiological variation of the normality that does not require treatment unless it becomes symptomatic.The aim of this research was to investigate the reason why some individuals with flexible flatfoot become symptomatic by analysis of the differences in the relative alignment of each segment of the foot between symptomatic and asymptomatic patients with idiopathic flexible flatfoot using radiographic measurements.Methods One hundred patients with idiopathic flexible flatfoot were retrospectively identified and divided into two groups:asymptomatic (n=50) and symptomatic (n=50).Standing anteroposterior and lateral radiographs of the foot were analyzed.Five measurements were calculated to describe the alignment of the foot.An independent-samples t-test and Logistic regression test were used for statistical analysis.Results Age and sex were similar in the two groups.The independent-samples test revealed significant differences in two parameters:the anteroposterior talonavicular coverage angle and the lateral talo-first metatarsal angle.When the Logistic regression test was performed,only the talonavicular coverage angle showed statistical significance.Conclusions The lateral displacement of the navicular bone,measured by the anteroposterior talonavicular coverage angle,seems to be related to the onset of symptoms.In individuals with otherwise normal flexible flatfoot,an increase in this angle might be an important risk factor for developing symptoms.

  4. Radiographic analysis of shoulder anatomical arthroplasty

    Arthroplasty is the standard treatment for advanced shoulder osteoarthritis. Modern prostheses designs have modular features whose size, shaft/head and body morphology can be adjusted. Total Shoulder Arthroplasty (TSA) provides better results. A complete X-ray follow-up is essential to assess the results and evaluate the survival rates of a shoulder prosthesis. Antero-posterior at 40 deg. in both internal and external rotation (true AP view) and axillary view are recommended to assess the following parameters: orientation and translation of the humeral component, offset, size and height of the humeral head, acromio-humeral distance, distribution and fixation of the cement, stress shielding and cortical resorption, radiolucent lines, subsidence and tilt, glenoid wear and 'bone stock', prostheses instability, glenoid component shift. Shoulder hemiarthroplasty can lead to glenoid wear; the true AP film at 40 deg. of internal rotation provides the best profile of gleno-humeral joint to depict glenoid erosion. Shift of the glenoid component in TSA is identified as tilting or medial migration on true AP and axillary views in the early postoperative period (1-2 months) and at minimum of 2 years. An exhaustive radiographic analysis remains essential to monitor the prosthetic implant and detect early and late complications or risk factors of prosthetic loosening.

MATERIALS AND METHODS: A combination of patients treated by the authors in the recent past and a literature review of patients with pelvic Actinomycosis were assessed for diographic, clinical and predisposing co-factors. An analysis is made of age distribution, gender, diagnostic methods and treatment concepts. RESULTS: Thirty-three patients were included in the study that included 2 current patients and 31 obtained from literature review. There were 27 fiales (age range 16 - 69 years, mean 38 years and 6 males (16 - 55 years, mean 36 years. Presenting signs and symptoms were lower abdominal mass in 28 (85%; lower abdominal pain in 21 (63%; vaginal discharge or hiaturia in 7 (22%. Two patients developed fistulae (entero-vesico 1; vesico-cutaneous 1. Nineteen (70% of the 27 fiale patients had intra-uterine contraceptive devices (IUD. Four patients (12.5% (3 males and 1 fiale had urachus or urachal rinants. Cystoscopy in 12 patients noted an extrinsic mass effect, bullous edia and in one patient vegetative proliferation proven to be a chronic inflammatory change. Exploratory laparotomy was performed in 32 of the 33 patients who had excision of mass and involved organs. Diagnosis was established by histologic examination of rioved tissue. Penicillin (6 weeks therapy was utilized to control infections. CONCLUSION: Pelvic actinomycosis mimics pelvic malignancy and may be associated with the long-term use of intra-uterine contraceptive devices, and persistent urachal rinants. Rioval of infected mass and antibiotic therapy will eradicate the inflammatory process.

    Taylor, Erin C. [Boston Children' s Hospital, Department of Radiology, Boston, MA (United States); Taylor, George A. [Boston Children' s Hospital, Department of Radiology, Boston, MA (United States); Harvard Medical School, Department of Radiology, Boston, MA (United States)


    Central venous catheters (CVCs) are commonly used in children, and inadvertent arterial or extravascular cannulation is rare but has potentially serious complications. To identify the radiographic signs of arterial placement of CVCs. We retrospectively reviewed seven cases of arterially malpositioned CVCs on chest radiograph. These cases were identified through departmental quality-assurance mechanisms and external consultation. Comparison of arterial cases was made with 127 age-matched chest radiographs with CVCs in normal, expected venous location. On each anteroposterior (AP) radiograph we measured the distance of the catheter tip from the right lateral border of the thoracic spine, and the angle of the vertical portion of the catheter relative to the midline. On each lateral radiograph we measured the angle of the vertical portion of each catheter relative to the anterior border of the thoracic spine. When bilateral subclavian catheters were present, the catheter tips were described as crossed, overlapping or uncrossed. On AP radiographs, arterially placed CVCs were more curved to the left, with catheter tip positions located farther to the left of midline than normal venous CVCs. When bilateral, properly placed venous catheters were present, all catheters crossed at the level of the superior vena cava (SVC). When one of the bilateral catheters was in arterial position, neither of the catheters crossed or the inter-catheter crossover distance was exaggerated. On lateral radiographs, there was a marked anterior angulation of the vertical portion of the catheter (mean angle 37 ± 15 standard deviation [SD] in arterial catheters versus 5.9 ± 8.3 SD in normally placed venous catheters). Useful radiographic signs suggestive of unintentional arterial misplacement of vascular catheters include leftward curvature of the vertical portion of the catheter, left-side catheter tip position, lack of catheter crossover on the frontal radiograph, as well as exaggerated

  8. [Pelvic floor muscle training and pelvic floor disorders in women]. (United States)

    Thubert, T; Bakker, E; Fritel, X


    Our goal is to provide an update on the results of pelvic floor rehabilitation in the treatment of urinary incontinence and genital prolapse symptoms. Pelvic floor muscle training allows a reduction of urinary incontinence symptoms. Pelvic floor muscle contractions supervised by a healthcare professional allow cure in half cases of stress urinary incontinence. Viewing this contraction through biofeedback improves outcomes, but this effect could also be due by a more intensive and prolonged program with the physiotherapist. The place of electrostimulation remains unclear. The results obtained with vaginal cones are similar to pelvic floor muscle training with or without biofeedback or electrostimulation. It is not known whether pelvic floor muscle training has an effect after one year. In case of stress urinary incontinence, supervised pelvic floor muscle training avoids surgery in half of the cases at 1-year follow-up. Pelvic floor muscle training is the first-line treatment of post-partum urinary incontinence. Its preventive effect is uncertain. Pelvic floor muscle training may reduce the symptoms associated with genital prolapse. In conclusion, pelvic floor rehabilitation supervised by a physiotherapist is an effective short-term treatment to reduce the symptoms of urinary incontinence or pelvic organ prolapse.

    To evaluate the plain radiographic and CT findings of the necrotizing fasciitis. We retrospectively reviewed the radiologic findings of 4 cases with necrotizing fasciitis. Three cases were proven pathologically. We evaluated pattern and extent of the gas shadows in plain films. CT findings were analysed, with emphasis on : (a) gas pattern, (b) extent, (c) location and involved site, (d) associated focal abscess, and (e) swelling of the adjacent muscles. On plain radiographs, four cases showed streaky or mottled gas densities in the pelvis, three cases in the perineum, one case in the abdomen, and two cases in the thigh. On CT images, gas pattern was mottled and streaky appearance with swelling of the adjacent muscles. Gas shadows located in the extraperitoneal space in four cases, fascial layer in four cases, and subcutaneous layer in four cases. There were gas shadows in pelvic wall, perineum, abdominal wall, buttock, thigh, and scrotum. Focal low density lesion suggestive of focal abscess was not visualized. Plain radiography is useful for early diagnosis of the necrotizing fasciitis and CT is very useful for detection of precise location and extent of the disease. CT is also useful for differentiation of necrotizing fasciitis from focal abscess and cellulitis.

    Objective: To investigate the effects of anteroposterior cricoid spliting interposition costal grafting for moderate and severe laryngotracheal stenosis in children. Methods: From 1995 to 2005, 87 children (aged 1.2 to 14 years) with moderate and severe glottic and subglottic stenosis were retrospectively studied. They were operated with cricoid spliting laryngotracheal reconstruction in our hospital. All of 87 patients were tracheostomy-dependent before surgery. Results: Eighty-five patients (95%) were successfully decannnulated and got an effective phonation. The follow-up time was more than 5 years. The effect of operation was satisfactory and the growth and development of children was normal. Conclusion: Anteroposterior cricoid split interposition costal cartilage graft is a safe and effective treatment method formoderate and severe glottic and subglottic stenosis in children.

  11. Smed-betacatenin-1 is required for anteroposterior blastema polarity in planarian regeneration. (United States)

    Petersen, Christian P; Reddien, Peter W


    Planarian flatworms can regenerate heads at anterior-facing wounds and tails at posterior-facing wounds throughout the body. How this regeneration polarity is specified has been a classic problem for more than a century. We identified a planarian gene, Smed-betacatenin-1, that controls regeneration polarity. Posterior-facing blastemas regenerate a head instead of a tail in Smed-betacatenin-1(RNAi) animals. Smed-betacatenin-1 is required after wounding and at any posterior-facing wound for polarity. Additionally, intact Smed-betacatenin-1(RNAi) animals display anteriorization during tissue turnover. Five Wnt genes and a secreted Frizzled-related Wnt antagonist-like gene are expressed in domains along the anteroposterior axis that reset to new positions during regeneration, which suggests that Wnts control polarity through Smed-betacatenin-1. Our data suggest that beta-catenin specifies the posterior character of the anteroposterior axis throughout the Bilateria and specifies regeneration polarity in planarians.

  13. Musculoskeletal etiologies of pelvic pain. (United States)

    Prather, Heidi; Camacho-Soto, Alejandra


    Several musculoskeletal diagnoses are frequently concomitant with pelvic floor pathology and pain. The definition of pelvic pain itself often depends on the medical specialist evaluating the patient. Because there is variability among disorders associated with pelvic pain, patients may seek treatment for extended periods as various treatment options are attempted. Further, health care providers should recognize that there may not be a single source of dysfunction. This article discusses the musculoskeletal disorders of the pelvic girdle (structures within the bony pelvis) and their association with lumbar spine and hip disorders.

    A middle-aged man was being investigated for constipation. Abdominal radiographs incidentally revealed a large, densely calcified, rounded mass within the pelvic cavity. A CT scan was performed followed by surgical excision with a differential diagnosis of calcified hematoma and an enlarged calcified lymph nodal mass. Histopathological investigation revealed a primary mesenteric extraskeletal osteosarcoma. To the best of our knowledge, a primary extraskeletal osteosarcoma arising from the mesentery has not been described previously in the English literature. The radiological features and differential diagnosis are discussed. (orig.)

    Surgery in hemophilic patients is a challenge for the general surgeon. Hemophilic pseudotumor is a rare complication occurring in 1-2% of hemophiliacs and affecting mainly patients with severe disease or those who have developed antibodies to factor VIII or IX. A number of alternatives are available for the management of these tumors, including conservative treatment, surgical removal, percutaneous drainage, embolization, and external radiation. The only definitive treatment is surgical excision. We report a case of hemophilic pseudotumor of the pelvic bone. Treatment consisted of surgical resection after arterial embolization using factor replacement to achieve hemostasis.

    Archer, B.R.; Whitmore, R.C.; North, L.B.; Bushong, S.C.


    The dose to active bone marrow resulting from anteroposterior (AP) and posteroanterior (PA) chest examinations was estimated using an Alderson Rando phantom and extruded lithium fluoride dosimeters. The AP projections resulted in a mean marrow dose range of 1.9 to 2.6 mrad (0.019 to 0.026 mGy) as compared to doses for PA projections of 3.4 to 3.8 mrad (0.034 to 0.038 mGy) for optimally diagnostic exposures taken at 70, 90, and 120 kVp.

  19. Clinical correlates of decreased anteroposterior metabolic gradients in positron emission tomography (PET) of schizophrenic patients

    The finding in schizophrenic patients of a reversal of the normal frontal to posterior pattern of brain metabolic activity with positron emission tomography (PET) is of interest, but its relevance to psychopathology is unknown. Using PET, the authors studied 21 patients with chronic schizophrenia and 21 age- and sex-matched control subjects. Although eight of the 21 patients and only one of the control subjects showed a relatively lower anteroposterior metabolic gradient, no clinical correlates of this finding were noted. In addition, cerebral atrophy, as determined by CAT scan, was not associated with this aberrant metabolic pattern.

  20. Peritoneal tuberculosis: radiographic diagnosis

    Directory of Open Access Journals (Sweden)

    Carolina Ospina-Moreno


    Full Text Available Peritoneal tuberculosis (TB is an extrapulmonary form of presentation of tuberculosis. HIV infection is a primary risk factor for this condition. Diagnosis requires microbiological or histopathological confirmation in addition to supporting radiological imaging studies. Abdominal ultrasonography and CT are useful to obtain a radiographic diagnosis, with typical findings including diffuse peritoneal thickening, presence of ascites in varying volumes, adenopathies, and caseating nodes. We report 2 cases of patients with ascites and nodular peritoneal thickening on diagnostic images, as well as high CA-125 levels in laboratory tests. In both patients, a diagnosis of peritoneal tuberculosis was reached following a US-guided peritoneal biopsy.

  1. Laparoscopy for pelvic floor disorders. (United States)

    Van Geluwe, B; Wolthuis, A; D'Hoore, A


    Surgical treatment of pelvic floor disorders has significantly evolved during the last decade, with increasing understanding of anatomy, pathophysiology and the minimally-invasive 'revolution' of laparoscopic surgery. Laparoscopic pelvic floor repair requires a thorough knowledge of pelvic floor anatomy and its supportive components before repair of defective anatomy is possible. Several surgical procedures have been introduced and applied to treat rectal prolapse syndromes. Transabdominal procedures include a variety of rectopexies with the use of sutures or prosthesis and with or without resection of redundant sigmoid colon. Unfortunately there is lack of one generally accepted standard treatment technique. This article will focus on recent advances in the management of pelvic floor disorders affecting defecation, with a brief overview of contemporary concepts in pelvic floor anatomy and different laparoscopic treatment options.

  2. Management of pelvic organ prolapse. (United States)

    Ahmed, Faisal; Sotelo, Tiffany


    Symptomatic pelvic organ prolapse can afflict up to 10% of women. Urinary incontinence, voiding dysfunction or difficulty possibly related to bladder outlet obstruction are common symptoms. Infrequently hydronephrosis or defecatory dysfunction can be seen. The management of pelvic organ prolapse (POP) should start with adequate assessment of all pelvic floor complaints. If a patient is not symptomatic, surgical intervention is usually not indicated. While the use of a variety of graft materials are available today including porcine, dermal and synthetic grafts, that are used in some surgical approaches to pelvic organ prolapse, other more conservative approaches may prove beneficial to many patients. This article describes our approach to the patient with pelvic organ prolapse.

  4. Patterning of anteroposterior body axis displayed in the expression of Hox genes in sea cucumber Apostichopus japonicus. (United States)

    Kikuchi, Mani; Omori, Akihito; Kurokawa, Daisuke; Akasaka, Koji


    The presence of an anteroposterior body axis is a fundamental feature of bilateria. Within this group, echinoderms have secondarily evolved pentameral symmetric body plans. Although all echinoderms present bilaterally symmetric larval stages, they dramatically rearrange their body axis and develop a pentaradial body plan during metamorphosis. Therefore, the location of their anteroposterior body axis in adult forms remains a contentious issue. Unlike other echinoderms, sea cucumbers present an obvious anteroposterior axis not rearranged during metamorphosis, thus representing an interesting group to study their anteroposterior axis patterning. Hox genes are known to play a broadly conserved role in anteroposterior axis patterning in deuterostomes. Here, we report the expression patterns of Hox genes from early development to pentactula stage in sea cucumber. In early larval stages, five Hox genes (AjHox1, AjHox7, AjHox8, AjHox11/13a, and AjHox11/13b) were expressed sequentially along the archenteron, suggesting that the role of anteroposterior patterning of the Hox genes is conserved in bilateral larvae of echinoderms. In doliolaria and pentactula stages, eight Hox genes (AjHox1, AjHox5, AjHox7, AjHox8, AjHox9/10, AjHox11/13a, AjHox11/13b, and AjHox11/13c) were expressed sequentially along the digestive tract, following a similar expression pattern to that found in the visceral mesoderm of other bilateria. Unlike other echinoderms, pentameral expression patterns of AjHox genes were not observed in sea cucumber. Altogether, we concluded that AjHox genes are involved in the patterning of the digestive tract in both larvae and metamorphosis of sea cucumbers. In addition, the anteroposterior axis in sea cucumbers might be patterned like that of other bilateria.

  5. Comparison of Lumbar Lordosis in Lateral Radiographs in Standing Position with supine MR Imaging in consideration of the Sacral Slope. (United States)

    Benditz, Achim; Boluki, Daniel; Weber, Markus; Zeman, Florian; Grifka, Joachim; Völlner, Florian


    Purpose To investigate the influence of sacral slope on the correlation between measurements of lumbar lordosis obtained by standing radiographs and magnetic resonance images in supine position (MRI). Little information is available on the correlation between measurements of lumbar lordosis obtained by radiographic and MR images. Most relevant studies have shown correlations for the thoracic spine, but detailed analyses on the lumbar spine are lacking. Methods MR images and standing lateral radiographs of 63 patients without actual low back pain or radiographic pathologies of the lumbar spine were analyzed. Standing radiographic measurements included the sagittal parameters pelvic incidence (PI) pelvic tilt (PT), and sacral slope (SS); MR images were used to additionally measure lumbar L1-S1 lordosis and single level lordosis. Differences between radiographic and MRI measurements were analyzed and divided into 4 subgroups of different sacral slope according to Roussouly's classification. Results Global lumbar lordosis (L1-S1) was 44.99° (± 10 754) on radiographs and 47.91° (± 9.170) on MRI, yielding a clinically relevant correlation (r = 0.61, p consideration of the Sacral Slope.

    Darab Gholami Borujeni


    Full Text Available Objective: One of the most important goals of orthodontic treatment is to create an esthetic, well balanced facial profile. However, the components of a well-balanced Iranian facial profile have not yet been established. The purpose of this study was to evaluate the anteroposterior lip position of the Iranian population and to compare the perception of orthodontists, dental students and orthodontic patients using a series of silhouettes with varying anteroposterior lip positions.Materials and Methods: Average female and male silhouette profiles were constructed from the profiles of 30 Iranian men and women with a normal skeletal relationship. The lips in each average profile were protruded or retruded in 2-mm increments and the 7 images were arranged randomly. Thirty orthodontists, 30 dental students and 30 orthodontic patients were asked to score each silhouette from 1 (very bad to 5 (very good.Results: Both the orthodontists and the students preferred the average profile for men and slightly more retruded lip position for women. Orthodontic patients had a wide range of preference for men and selected more retruded lip positions for women. The least-favored profile was the most protrusive in the 3 groups.Conclusion: These findings suggest that Iranian orthodontists, dental students and orthodontic patients prefer an average profile for men and slightly retruded profiles for women.

  7. Reliability of soft tissue references for anteroposterior measurement of dental bases. (United States)

    Ferrario, V F; Sforza, C; Serrao, G; Colombo, A; Ciusa, V; Bignotto, M


    The aims of the present investigation were to devise a new anteroposterior measurement of maxillomandibular discrepancies that would consider both hard and soft tissue contributions, and to verify the correlation of this measurement to a well-established linear assessment of anteroposterior discrepancy. On the pretreatment lateral cephalographs of 300 orthodontic patients (162 males, 138 females) aged between 6 and 50 years, the Wits appraisal and a new "soft tissue" Wits appraisal (linear distance between the projections of soft tissue A and B points on the bisecting occlusal plane) were measured. In the analyzed sample, the former was more variable than the latter. The two measurements were significantly correlated to each other without sex- or age-characteristic patterns. From the correlation, reference values for the new measurement were estimated and found to be between -1.9 mm and 5.4 mm for individuals with a normal occlusion. The new measurement could allow a more careful evaluation of the soft tissue drape together with the underlying hard tissue structure.

  8. Post Pelvic Radiotherapy Bony Changes

    Energy Technology Data Exchange (ETDEWEB)

    Huh, Seung Jae [Samsung Medical Center, Seoul (Korea, Republic of)


    There has been recent interest in radiation-induced bone injury in clinical conditions, especially for pelvic insufficiency fracture (PIF). A PIF is caused by the effect of normal or physiological stress on bone with demineralization and decreased elastic resistance. Pelvic radiotherapy (RT) can also contribute to the development of a PIF. A PIF has been regarded as a rare complication with the use of megavoltage equipment. However, recent studies have reported the incidence of PIFs as 8.2{approx}20% after pelvic RT in gynecological patients, an incidence that was higher than previously believed. The importance of understanding a PIF lies in the potential for misdiagnosis as a bony metastasis. If patients complain of pelvic pain after whole-pelvis radiation therapy, the presence of a PIF must be considered in the differential diagnosis. The use of multibeam arrangements and conformal RT to reduce the volume and dose of irradiated pelvic bone can be helpful to minimize the risk of fracture. In addition to a PIF, osteonecrosis and avascular necrosis of the femoral head can develop after radiation therapy. Osteoradionecrosis of the pelvic bone is a clinical diagnostic challenge that must be differentiated from an osseous metastasis. A post-radiation bone sarcoma can result as a long-term sequela of pelvic irradiation for uterine cervical cancer.

    David Canes


    Full Text Available PURPOSE: Our goal was to assess outcomes of a selective drain placement strategy during laparoscopic radical prostatectomy (LRP with a running urethrovesical anastomosis (RUVA using cystographic imaging in all patients. Materials and Methods: A retrospective chart review was performed for all patients undergoing LRP between January 2003 and December 2004. The anastomosis was performed using a modified van Velthoven technique. A drain was placed at the discretion of the senior surgeon when a urinary leak was demonstrated with bladder irrigation, clinical suspicion for a urinary leak was high, or a complex bladder neck reconstruction was performed. Routine postoperative cystograms were obtained. RESULTS: 208 patients underwent LRP with a RUVA. Data including cystogram was available for 206 patients. The overall rate of cystographic urine leak was 5.8%. A drain was placed in 51 patients. Of these, 8 (15.6% had a postoperative leak on cystogram. Of the 157 undrained patients, urine leak was radiographically visible in 4 (2.5%. The higher leak rate in the drained vs. undrained cohort was statistically significant (p = 0.002. Twenty-four patients underwent pelvic lymph node dissection (8 drained, 16 undrained. Three undrained patients developed lymphoceles, which presented clinically on average 3 weeks postoperatively. There were no urinomas or hematomas in either group. CONCLUSIONS: Routine placement of a pelvic drain after LRP with a RUVA is not necessary, unless the anastomotic integrity is suboptimal intraoperatively. Experienced clinical judgment is essential and accurate in identifying patients at risk for postoperative leakage. When suspicion is low, omitting a drain does not increase morbidity.

  11. Herniation pits in the femoral neck: a radiographic indicator of femoroacetabular impingement?

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Jin Ah; Park, Ji Seon; Ryu, Kyungnam [Kyung Hee University, Department of Radiology, Kyung Hee University Medical Center, Seoul (Korea, Republic of); Jin, Wook [Kyung Hee University, Department of Radiology, East-West Neo Medical Center, Seoul (Korea, Republic of)


    The purpose was to assess the significance of herniation pits in the femoral neck for radiographic diagnosis of femoroacetabular impingement (FAI). Eighty hips in 62 patients (bilateral in 18) with neutral pelvic orientation were enrolled. Herniation pits were diagnosed when they were located at the anterosuperior femoral neck, close to the physis, and with a diameter of >3 mm. The five radiographic signs of FAI were used: lateral center edge angle (LCE) >39 , acetabular index (AI) {<=}0, extrusion index (EI) <25%, acetabular retroversion, and pistol-grip deformity. Patients with radiographs suggesting FAI were retrospectively correlated with their clinical symptoms. Positive radiographic signs were observed in 7 hips with LCE, 7 with AI, and 80 with EI criteria. Only 3 hips out of 80 (3.8%) showed all of the signs. The acetabular retroversion and pistol-grip deformity were seen in 12/80 and 3/80 hips, respectively. The total number of hips that met radiographic criteria for FAI, including pincer type and cam type, was 18 (23%). However, none of these hips were clinically diagnosed with FAI. All symptomatic hips (11/80) presented only with nonspecific pain, and 2 hips out of 11 showed radiographic signs of FAI. The low frequency of positive radiographic signs suggesting FAI with related symptoms among patients with herniation pits suggests that herniation pits have limited significance in the diagnosis of FAI. Therefore it can be concluded that an incidental finding of herniation pits does not necessarily imply a correlation with FAI. (orig.)

  13. Descriptive quantitative analysis of hallux abductovalgus transverse plane radiographic parameters. (United States)

    Meyr, Andrew J; Myers, Adam; Pontious, Jane


    Although the transverse plane radiographic parameters of the first intermetatarsal angle (IMA), hallux abductus angle (HAA), and the metatarsal-sesamoid position (MSP) form the basis of preoperative procedure selection and postoperative surgical evaluation of the hallux abductovalgus deformity, the so-called normal values of these measurements have not been well established. The objectives of the present study were to (1) evaluate the descriptive statistics of the first IMA, HAA, and MSP from a large patient population and (2) to determine an objective basis for defining "normal" versus "abnormal" measurements. Anteroposterior foot radiographs from 373 consecutive patients without a history of previous foot and ankle surgery and/or trauma were evaluated for the measurements of the first IMA, HAA, and MSP. The results revealed a mean measurement of 9.93°, 17.59°, and position 3.63 for the first IMA, HAA, and MSP, respectively. An advanced descriptive analysis demonstrated data characteristics of both parametric and nonparametric distributions. Furthermore, clear differentiations in deformity progression were appreciated when the variables were graphically depicted against each other. This could represent a quantitative basis for defining "normal" versus "abnormal" values. From the results of the present study, we have concluded that these radiographic parameters can be more conservatively reported and analyzed using nonparametric descriptive and comparative statistics within medical studies and that the combination of a first IMA, HAA, and MSP at or greater than approximately 10°, 18°, and position 4, respectively, appears to be an objective "tipping point" in terms of deformity progression and might represent an upper limit of acceptable in terms of surgical deformity correction.

  15. The immediate effect of the variation of anteroposterior laterotrusive contacts on the elevator EMG activity. (United States)

    Manns, A; Rocabado, M; Cadenasso, P; Miralles, R; Cumsille, M A


    A unilateral maxillary splint divided into three occlusal blocks was built for eight healthy young adults. The three blocks allowed the anteroposterior location of the laterotrusive contacts to vary and to distribute the occlusal force over equivalent periodontal surfaces. The ipsilateral masseteric and temporalis electromyogram (EMG) activities were recorded with surface electrodes during maximal voluntary clenching. The elevator EMG activity with the anterior occlusal block in place was significantly lower than with the intermediate or posterior blocks. The reduction for both elevators with the intermediate block in place did not show a significant variation in comparison to the posterior block of the three blocks inserted. The elevator activity with the three occlusal blocks did not differ from that recorded with the posterior block alone. Neurophysiologic and biomechanical explanations are given related to this laterotrusive elevator muscular behavior.

  16. Anteroposterior patterning in hemichordates and the origins of the chordate nervous system (United States)

    Lowe, Christopher J.; Wu, Mike; Salic, Adrian; Evans, Louise; Lander, Eric; Stange-Thomann, Nicole; Gruber, Christian E.; Gerhart, John; Kirschner, Marc


    The chordate central nervous system has been hypothesized to originate from either a dorsal centralized, or a ventral centralized, or a noncentralized nervous system of a deuterostome ancestor. In an effort to resolve these issues, we examined the hemichordate Saccoglossus kowalevskii and studied the expression of orthologs of genes that are involved in patterning the chordate central nervous system. All 22 orthologs studied are expressed in the ectoderm in an anteroposterior arrangement nearly identical to that found in chordates. Domain topography is conserved between hemichordates and chordates despite the fact that hemichordates have a diffuse nerve net, whereas chordates have a centralized system. We propose that the deuterostome ancestor may have had a diffuse nervous system, which was later centralized during the evolution of the chordate lineage.

    In order to determine the diagnostic value of CT in pelvic trauma, esp. acetabular fracture, we analysed 32 cases of pelvic trauma with conventional radiographic and computed tomographic findings. The results were as follows : 1. There were 26 males and 6 female and peak age span was 4th decade. 2. In 32 cases of acetabular fractures, single column fracture were diagnosed in 20 cases and two column fracture in 12 cases by CT. Among single column fractures, anterior column fractures were 12 cases and posterior column fractures were 8 cases. Complex fracture was most common type in two column fractures. 3. In 32 cases of acetabular fractures diagnosed by CT, 18 cases could be detected by plain X-ray. 4. Intraarticular bony fragments were detected on CT in 11 cases and on plain X-ray in 2 cases. 5. Combined soft issue injuries were 13 cases of pelvic hematoma, 1 case of retroperitoneal hematoma and 2 cases of hemarthrosis. 6. CT was useful in acetabular injury to delineated the extent and type of fracture, localized intraarticular bony fragments, characterize joint dislocation and detect the combined soft tissue injury.

  18. Function after pelvic tumour resection involving the acetabular ring. (United States)

    Nilsonne, U; Kreicbergs, A; Olsson, E; Stark, A


    Seven patients subjected to pelvic tumour resection involving the acetabular ring were analyzed with respect to function. In addition to conventional clinical assessment gait was analyzed objectively by means of an electronic walk-way and residual hip-muscle power tested by means of a Cybex II dynamometer. Functional results reported by the patients with respect to pain, walking and working capacity appeared better than those elicited by clinical examination. All patients exhibited a marked pelvic tilt and a positive Trendelenburg sign. Only one patient walked without any kind of support. Leg-length discrepancy was on an average 6 cm. Objective gait analysis disclosed that all patients had reduced weight-bearing time on the operated side as compared to the non-operated. This, however, was clearly less pronounced for those patients who appeared best with respect to pain, walking and working capacity. These patients also showed the best hip extension power which appeared more important from a functional point of view than hip flexion and, surprisingly, hip abduction power. Radiographic examination showed that bony support for the proximal femur, provided either by the formation of a bone shelf from the remaining iliac bone or by the remaining iliac bone itself, was of decisive importance for function. The results of the present study show that pelvic tumour resection involving the acetabular ring, provided radical tumour removal can be achieved, constitutes a feasible alternative to hemipelvectomy from a functional point of view.

    Generally, descriptions of the pelvic floor are discordant, since its complex structures and the complexity of pathological disorders of such structures; commonly the descriptions are sectorial, concerning muscles, fascial developments, ligaments and so on. On the contrary to understand completely nature and function of the pelvic floor it is necessary to study it in the most unitary view and in the most global aspect, considering embriology, philogenesy, anthropologic development and its mul...

  20. Salpingitis and pelvic inflammatory disease. (United States)

    Swinker, M L


    Chlamydia trachomatis is becoming an increasingly important etiologic agent. The physician must also be aware of other nongonococcal causes of pelvic inflammatory disease, such as Mycoplasma, Ureaplasma, coliforms and anaerobes. Epidemiologic characteristics of the various microorganisms differ, with the frequency of nongonococcal disease higher in older women. Intrauterine devices increase the potential for pelvic inflammatory disease. The rising incidence of nongonococcal and dual infections has led to therapeutic and preventive techniques aimed at multiple etiologies.

  1. Prevention of pelvic radiation disease

    Lorenzo; Fuccio; Leonardo; Frazzoni; Alessandra; Guido


    Pelvic cancers are among the most frequently diagnosed cancers worldwide. Treatment of patients requires a multidisciplinary approach that frequently includes radiotherapy. Gastrointestinal(GI) radiation-induced toxicity is a major complication and the transient or long-term problems, ranging from mild to very severe, arising in non-cancerous tissues resulting from radiation treatment to a tumor of pelvic origin, are actually called as pelvic radiation disease. The incidence of pelvic radiation disease changes according to the radiation technique, the length of follow up, the assessmentmethod, the type and stage of cancer and several other variables. Notably, even with the most recent radiation techniques, i.e., intensity-modulated radiotherapy, the incidence of radiation-induced GI side effects is overall reduced but still not negligible. In addition, radiation-induced GI side effects can develop even after several decades; therefore, the improvement of patient life expectancy will unavoidably increase the risk of developing radiation-induced complications. Once developed, the management of pelvic radiation disease may be challenging. Therefore, the prevention of radiation-induced toxicity represents a reasonable way to avoid a dramatic drop of the quality of life of these patients. In the current manuscript we provide an updated and practical review on the best available evidences in the field of the prevention of pelvic radiation disease.

    Full Text Available : INTRODUCTION: Subtrochanteric fractures account for approximately 10-30% of all hip fractures, and they affect persons of all ages. Most frequently, these fractures are seen in 2 patient populations, namely older osteopenic patients after a low-energy fall and younger patients involved in high-energy trauma. A newer population of patients experience subtrochanteric fractures after bisphosphonate use. CASE PRESENTATION: A 45year old Indian woman presented at our orthopaedic outpatients department with 4 months history of pain in left hip and a 1 month history of inability to walk. She had pelvic irradiation for carcinoma of cervix 1 year earlier. Pelvic radiograph confirmed sub trochanteric fracture of left femur. CONCLUSION: Patients with hip pain who have been treated with pelvic irradiation should be thoroughly investigated for hip fractures.

  3. Symptomatic sacroiliac joint disease and radiographic evidence of femoroacetabular impingement. (United States)

    Morgan, Patrick M; Anderson, Anthony W; Swiontkowski, Marc F


    Symptomatic sacroiliac (SI) joint disease is poorly understood. The literature provides no clear aetiology for SI joint pathology, making evaluation and diagnosis challenging. We hypothesised that patients with documented sacroiliac pain might provide insight into the aetiology of these symptoms. Specifically, we questioned whether SI joint symptoms might be associated with abnormal hip radiographs. We reviewed the pelvic and hip radiographs of a prospectively collected cohort of 30 consecutive patients with SI joint pathology. This database included 33 hips from 30 patients. Radiographic analysis included measurements of the lateral centre edge angle, Tönnis angle, and the triangular index, of the ipsilateral hip. Evidence for retrotorsion of the hemipelvis was recorded. Hips were graded on the Tönnis grading system for hip arthrosis. In this cohort 14/33 (42%) of hips had evidence of significant osteoarthrosis indicated by Tönnis grade 2 or greater and 15/33 (45%) displayed subchondral cyst formation around the hip or head neck junction. In assessing acetabular anatomy, 21% (7/33) had retroversion, 12% (4/33) had a lateral centre edge angle >40° with 3% (1/33) >45°. Tönnis angle was arthrosis. The clinician should maintain FAI in the differential diagnosis when investigating patients with buttock pain.

    1. A study on chest radiographic findings of 54 cases with pneumonia like symptoms was performed. Of 54 cases, 8 cases were confirmed to be leptospirosis and 7 cases were leptospirosis combined with Korean hemorrhagic fever. 2. Of 8 cases of leptospirosis, 4 cases showed abnormal chest radiographic findings: acinar nodular type 2, massive confluent consolidation type 2. Of 7 cases of leptospirosis combined with Korean hemorrhagic fever: acinar nodular type 3, massive confluent consolidation type 1, and increased interstitial markings type 1 respectively. 3. It was considered to be difficult to diagnose the leptospirosis on chest radiographic findings alone, especially the case combined with Korean hemorrhagic fever.

  5. Pelvic parameters of sagittal balance in extreme lateral interbody fusion for degenerative lumbar disc disease. (United States)

    Johnson, R D; Valore, A; Villaminar, A; Comisso, M; Balsano, M


    There is increasing interest in the use of pelvic indices to evaluate sagittal balance and predict outcomes in patients with spinal disease. Conventional posterior lumbar fusion techniques may adversely affect lumbar lordosis and spinal balance. Minimally invasive fusion of the lumbar spine is rapidly becoming a mainstay of treatment of lumbar degenerative disc disease. To our knowledge there are no studies evaluating the effect of extreme lateral interbody fusion (XLIF) on pelvic indices. Hence, our aim was to study the effect of XLIF on pelvic indices related to sagittal balance, and report the results of a prospective longitudinal clinical study and retrospective radiographic analyses of patients undergoing XLIF in a single centre between January 2009 and July 2011. Clinical outcomes are reported for 30 patients and the retrospective analyses of radiographic data is reported for 22 of these patients to assess global and segmental lumbar lordosis and pelvic indices. Effect of XLIF on the correction of scoliotic deformity was assessed in 15 patients in this series. A significant improvement was seen in the visual analogue scale score, the Oswestry Disability Index and the Short Form-36 at 2months and 6months (p0.2). Global lumbar lordosis was not affected by XLIF (p>0.4). XLIF significantly increased segmental lumbar lordosis by 3.3° (psagittal balance. Long-term follow-up with a larger cohort will be required to further evaluate the effects of XLIF on sagittal balance.

    The objective was to determine the value of radiographs in young adults with non-acute knee symptoms who are scheduled for magnetic resonance imaging (MRI). Nine hundred and sixty-one consecutive patients aged between 16 and 45 years with knee symptoms of at least 4 weeks' duration were prospectively included in three participating hospitals. After applying exclusion criteria, 798 patients remained. Exclusion criteria were previous knee surgery (including arthroscopy) or MRI, history of rheumatoid arthritis, clinical diagnosis of retropatellar chondromalacia, contra-indication for MRI and recent trauma. We identified two groups: group A with no history of trauma (n = 332), and group B with an old (>4 weeks) history of trauma (n = 466). Patients had a standardized history taken, and underwent a physical exam, antero-posterior (AP) and lateral radiographs and MRI. We evaluated the radiographs and MRI for osseous lesions, articular surface lesions, fractures, osteoarthritis, loose bodies, bone marrow edema and incidental findings. Subsequently, patients with osseous abnormalities (Kellgren grade 1 and 2 excluded) on radiographs and a matched control group was evaluated again using MRI without radiographs. Median duration of symptoms was 20 weeks. In group A, radiographs showed 36 osseous abnormalities in 332 patients (10.8%). Only 13 of these, all Kellgren grade 1 osteoarthritis, were not confirmed on MRI. MRI showed 72 (21.7%) additional abnormalities not confirmed on radiographs. In group B, radiographs showed 40 osseous abnormalities (8.6%) in 466 patients. Only 15 of these, all Kellgren grade 1 osteoarthritis, were not confirmed on MRI. MRI showed 194 (41.6%) additional abnormalities not confirmed on radiographs. The second evaluation of MRI without radiographs in 34 patients was identical to the first MRI evaluation. Common lesions were significantly more often diagnosed with MRI than with radiographs. Radiographs should not be obtained routinely when MRI is

  7. Managing chronic pelvic pain following reconstructive pelvic surgery with transvaginal mesh. (United States)

    Gyang, Anthony N; Feranec, Jessica B; Patel, Rakesh C; Lamvu, Georgine M


    In 2001, the US Food and Drug Administration (FDA) approved the first transvaginal mesh kit to treat pelvic organ prolapse (POP). Since the introduction of vaginal mesh kits, some vaginal meshes have been associated with chronic pelvic pain after reconstructive pelvic floor surgery. Pelvic pain results in between 0 % and 30 % of patients following transvaginal mesh placement. Common causes of chronic pelvic pain include pelvic floor muscle spasm, pudendal neuralgia, and infection. Paucity of data exists on the effective management of chronic pelvic pain after pelvic reconstructive surgery with mesh. We outline the management of chronic pelvic pain after transvaginal mesh placement for reconstructive pelvic floor repair based on our clinical experience and adaptation of data used in other aspects of managing chronic pelvic pain conditions.

    The detailed radiographic features of triploidy, a fatal congenital disorder with 69 chromosomes, have not previously been reported. Radiographs of ten liveborn infants with chromosomally confirmed triploidy showed six findings highly suggestive of this diagnosis: harlequin orbits, small anterior fontanelle, gracile ribs, diaphyseal overtubulation of long bones, upswept clavicles and antimongoloid pelvis. Sixteen other less specific findings showed many similarities to those found in trisomy 18.

    The purpose of this study was to perform the radiographic measurements and temporomandibular joint evaluation in mandibular asymmetry. For this study, thirty-two patients who have mandibular asymmetry were selected and submentovertex, panoramic and lateral corrected tomographic radiographs were taken. Horizontal and vertical analysis using various landmarks on these radiographs were performed. Also radiographic and clinical evaluation of temporomandibular joint were obtained. The results were as follows: 1. On the submentovertex radiograph, the mean distance of Pogonion to midline was 5.0 {+-} 3.8 mm. 2. The mean distance of Pogonion to Gonion between the deviated and the contra-lateral side (p<0.001). 3. The distance difference of Pogonion to Gonion between the deviated and the contra-lateral side was significantly related to the degree of asymmetry (p<0.001). 4. On panoramic radiograph,the condylar height of the contral-lateral side was significantly longer than the one of the deviated side (p<0.001). 5. On lateral corrected tomogram, bony of temporomandibular joint was observed in 11 condyles of the deviated side and 9 condyles of the contra-lateral side. Erosion and ostephyte were the most common changes in both the deviated and the contra-lateral sides.

  13. Pelvic manikins as learning aids. (United States)

    Macintosh, M C; Chard, T


    The use of pelvic trainers in undergraduate teaching was evaluated, using a questionnaire based on examination findings of a series of four pelvic trainers by 20 medical students and 34 gynaecologists. The main outcome measures were the ability to correctly identify pelvic findings in the trainers, and the numbers of false positive findings. There were two adnexal masses in two of the trainers. One was correctly identified by 33 (14 (70%) medical students and 19 (56%) doctors) in one trainer, whereas the other was missed by 52 of 54 examiners. Prolapse was missed by 41 of 54. The normal pelvis was correctly identified by 30 (16 (80%) medical students and 20 (59%) doctors. There were 15 false positive identifications of adnexal masses (6 by medical students and 9 by doctors) and 22 false positive identification of uterine enlargements (5 by medical students and 17 by doctors). The pelvic trainers were of value in demonstrating the process of pelvic and speculum examination. Some of the clinical conditions emulated were missed by most of the gynaecologists, suggesting that they were not suitable for training students in abnormal findings. Although the figures were not statistically significant, there was a trend for qualified doctors rather than medical students to make false positive findings.

    Little Leaguer's shoulder is a syndrome involving the proximal humeral epiphyseal plate. Conservative treatment usually resolves the symptoms. However, there are no reports of a radiographic follow-up study of this disease. The purpose of this study was to show the radiographic healing process of Little Leaguer's shoulder. A total of 19 male baseball players diagnosed as having Little Leaguer's shoulder were retrospectively evaluated. The mean age at first presentation was 12.7 years. External rotation anteroposterior radiographs of the shoulder were taken. All patients were treated with rest from throwing, and no throwing was recommended until remodeling was confirmed. Follow-up radiographs were taken at 1-month intervals to assess healing. All patients were observed until healing was confirmed radiographically, after which they returned to baseball. The mean follow-up period was 8.5 months. In addition to radiography, patients were asked whether they had any symptoms and whether they had been able to return to baseball. At the first examination, radiographs showed a wider epiphyseal plate of the throwing side compared with the asymptomatic contralateral shoulder. Healing was observed in all cases. Healing occurred first along the medial side and was then extended laterally. The mean time required for healing was 4.7 months. All patients were able to return to playing baseball at their pre-injury level of play and were asymptomatic when examined at the final follow-up. The healing process of Little Leaguer's shoulder advanced from medial to lateral, and healing was achieved about 5 months after initial examination. (orig.)

  20. Treatment of proximal humeral fractures using anatomical locking plate: correlation of functional and radiographic results

    Directory of Open Access Journals (Sweden)

    Antonio Carlos Tenor Junior


    Full Text Available ABSTRACT OBJECTIVE: To correlate the functional outcomes and radiographic indices of proximal humerus fractures treated using an anatomical locking plate for the proximal humerus. METHODS: Thirty-nine patients with fractures of the proximal humerus who had been treated using an anatomical locking plate were assessed after a mean follow-up of 27 months. These patients were assessed using the University of California Los Angeles (UCLA score and their range of motion was evaluated using the method of the American Academy of Orthopedic Surgeons on the operated shoulder and comparative radiographs on both shoulders. The correlation between radiographic measurements and functional outcomes was established. RESULTS: We found that 64% of the results were good or excellent, according to the UCLA score, with the following means: elevation of 124°; lateral rotation of 44°; and medial rotation of thumb to T9. The type of fracture according to Neer's classification and the patient's age had significant correlations with the range of motion, such that the greater the number of parts in the fracture and the greater the patient's age were, the worse the results also were. Elevation and UCLA score were found to present associations with the anatomical neck-shaft angle in anteroposterior view; fractures fixed with varus deviations greater than 15° showed the worst results (p < 0.001. CONCLUSION: The variation in the neck-shaft angle measurements in anteroposterior view showed a significant correlation with the range of motion; varus deviations greater than 15° were not well tolerated. This parameter may be one of the predictors of functional results from proximal humerus fractures treated using a locking plate.

  1. Anteroposterior glide versus rotating platform low contact stress (LCS knee arthroplasty: a randomised controlled trial

    Directory of Open Access Journals (Sweden)

    Wynn-Jones Charles


    Full Text Available Abstract Background Fifty thousand knee replacements are performed annually in the UK at an estimated cost of £150 million. Post-operative improvement depends on a number of factors including implant design and patient associated factors. To our knowledge there are no published study's comparing the results of AP glide and rotating platform designs of LCS knee arthroplasty. Therefore we feel that a study is required to investigate and compare the effects of two types of LCS total knee arthroplasty on joint proprioception and range of motion. Methods/Design Patients will be randomised to receive either a LCS AP glide or Rotating platform prosthesis. Clinical scores (Oxford knee score, American knee society score, EuroQol, range of motion and proprioception will be assessed prior to and at 3,6, 12 and 24 months after the operation. Proprioception will be assessed in terms of absolute error angle (mean difference between the target angle and the response angle. Knee angles will be measured in degrees using an electromagnetic tracking device, Polhemus 3Space Fastrak that detects positions of sensors placed on the test limb. Student's t-test will be used to compare the mean of two groups. Discussion Evidence is lacking concerning the best prosthesis to use for patients undergoing total knee replacement. This pragmatic randomised trial will test the null hypothesis that anteroposterior glide LCS knee arthroplasty does not result in better post operative knee motion and proprioception as compared to rotating platform LCS knee.

  2. [The anteroposterior axis in echinoderms and displacement of the mouth in their phylogeny and ontogeny]. (United States)

    Rozhnov, S V


    The difference in the position of the anteroposterior axis in larval and adult echinoderms is related to the displacement of the mouth from the anterior end of the body to the posterior end in the phylogeny of echinoderms, which occurred in the course of the reorganization of their body plan from bilateral asymmetrical to radiosymmetrical. Traces of this phylogenetic process have been especially fully preserved in the ontogeny of crinoids. Other recent echinoderms have largely lost such traces. Dislocation of Hox-genes in sea urchins, resulting from the translocation of these genes to the 5' end of the chromosome and inversion of the anterior Hox-genes, is explained by the necessity to preserve the spatial and temporal colinearity in the course of the convergence of the starting and final stages of the mouth displacement process, similar to the elevation process in crinoids, and inclusion in the basic body plan of the structure of a rudiment now regulated directly by the anterior Hox-genes.

  3. Antero-posterior tissue polarity links mesoderm convergent extension to axial patterning. (United States)

    Ninomiya, Hiromasa; Elinson, Richard P; Winklbauer, Rudolf


    Remodelling its shape, or morphogenesis, is a fundamental property of living tissue. It underlies much of embryonic development and numerous pathologies. Convergent extension (CE) of the axial mesoderm of vertebrates is an intensively studied model for morphogenetic processes that rely on cell rearrangement. It involves the intercalation of polarized cells perpendicular to the antero-posterior (AP) axis, which narrows and lengthens the tissue. Several genes have been identified that regulate cell behaviour underlying CE in zebrafish and Xenopus. Many of these are homologues of genes that control epithelial planar cell polarity in Drosophila. However, elongation of axial mesoderm must be also coordinated with the pattern of AP tissue specification to generate a normal larval morphology. At present, the long-range control that orients CE with respect to embryonic axes is not understood. Here we show that the chordamesoderm of Xenopus possesses an intrinsic AP polarity that is necessary for CE, functions in parallel to Wnt/planar cell polarity signalling, and determines the direction of tissue elongation. The mechanism that establishes AP polarity involves graded activin-like signalling and directly links mesoderm AP patterning to CE.

    Patil, Sonali S; Alexander, Tara B; Uzman, J Akif; Lou, Chih-Hong; Gohil, Himika; Sater, Amy K


    The novel gene ashwin was isolated in a differential display screen for genes activated or up-regulated early in neural specification. ashwin is expressed maternally and zygotically, and it is up-regulated in the neural ectoderm after the midgastrula stage. It is expressed in the neural plate and later in the embryonic brain, eyes, and spinal cord. Overexpression of ashwin in whole embryos leads to anterior truncations and other defects. However, a second Organizer does not form, and the secondary axial structures may result from splitting of the Organizer, rather than axis duplication. Morpholino oligonucleotide-mediated reduction in ashwin expression leads to lethality or abnormalities in gastrulation, as well as significant apoptosis in midgastrula embryos. Apoptosis is also observed in midgastrula embryos overexpressing ashwin. Coexpression of ashwin with the bone morphogenetic protein-4 antagonist noggin has a synergistic effect on neural-specific gene expression in isolated animal cap ectoderm. Ashwin has no previously characterized domains, although two nuclear localization signals can be identified. Orthologues have been identified in the human, mouse, chicken, and pufferfish genomes. Our results suggest that ashwin regulates cell survival and anteroposterior patterning.

  7. Establishing the biomechanical properties of the pelvic soft tissues through an inverse finite element analysis using magnetic resonance imaging. (United States)

    Silva, M E T; Brandão, S; Parente, M P L; Mascarenhas, T; Natal Jorge, R M


    The mechanical characteristics of the female pelvic floor are relevant when explaining pelvic dysfunction. The decreased elasticity of the tissue often causes inability to maintain urethral position, also leading to vaginal and rectal descend when coughing or defecating as a response to an increase in the internal abdominal pressure. These conditions can be associated with changes in the mechanical properties of the supportive structures-namely, the pelvic floor muscles-including impairment. In this work, we used an inverse finite element analysis to calculate the material constants for the passive mechanical behavior of the pelvic floor muscles. The numerical model of the pelvic floor muscles and bones was built from magnetic resonance axial images acquired at rest. Muscle deformation, simulating the Valsalva maneuver with a pressure of 4 KPa, was compared with the muscle displacement obtained through additional dynamic magnetic resonance imaging. The difference in displacement was of 0.15 mm in the antero-posterior direction and 3.69 mm in the supero-inferior direction, equating to a percentage error of 7.0% and 16.9%, respectively. We obtained the shortest difference in the displacements using an iterative process that reached the material constants for the Mooney-Rivlin constitutive model (c10=11.8 KPa and c20=5.53 E-02 KPa). For each iteration, the orthogonal distance between each node from the group of nodes which defined the puborectal muscle in the numerical model versus dynamic magnetic resonance imaging was computed. With the methodology used in this work, it was possible to obtain in vivo biomechanical properties of the pelvic floor muscles for a specific subject using input information acquired non-invasively.

[University of Michigan, Department of Radiology, Ann Arbor, MI (United States); Magerkurth, Olaf [University Children' s Hospital, Department of Radiology, Basel (Switzerland); Kantonsspital Baden, Department of Radiology, Baden (Switzerland)


    To define osseous landmarks on tibia radiographs in order to establish age-related normal values characterizing physiological tibial bowing in children. Five hundred and twenty-six patients aged 0-17 years with normal radiographs of the lower legs were identified and retrospectively reviewed by two blinded radiologists. In anteroposterior (ap)/lateral (lat)-views, 3 lines defined tibial length and angulation. Line-A connecting proximal to distal corner of tibial metaphysic, lines B and C corresponding to corners of tibial metaphysis. Angle A/B defines proximal, A/C distal tibial-angulation. Tibial curvature is defined by distance of line-D parallel to A and tangential to tibial cortex. Normal values were calculated with linear-regression. Intra-/Interreader agreement were tested with a Bland-Altman-plot. Intrareader-agreement: Reader 1 showed a bias of -0.1, standard-deviation of bias was 1.9 and 95 %-limits-of-agreement -3.9- 3.7. Reader 2: -0.01, 2.4 and -4.7- 4.7. Interreader: 0.2, 1.6 and -2.9- 3.3. Angle-A/B ap was 80-100 , increasing with age (86.5-88); angle-AC ap was 82-107 (96.8-90.5), angle-AB lat was 81-107 (93.0-98.0); angle-AC lat was 76-102 (89.5-86.5); depth of curve ap was 0-11 % (8-3.5) and lat 2-13 %, (8.5-3.5). Age dependent tibial bowing can be assessed with this new measurement system and age-related normal-values characterizing physiological tibial bowing in children is established. (orig.)

  9. Pelvic floor muscle rehabilitation using biofeedback. (United States)

    Newman, Diane K


    Pelvic floor muscle exercises have been recommended for urinary incontinence since first described by obstetrician gynecologist Dr. Arnold Kegel more than six decades ago. These exercises are performed to strengthen pelvic floor muscles, provide urethral support to prevent urine leakage, and suppress urgency. In clinical urology practice, expert clinicians also teach patients how to relax the muscle to improve bladder emptying and relieve pelvic pain caused by muscle spasm. When treating lower urinary tract symptoms, an exercise training program combined with biofeedback therapy has been recommended as first-line treatment. This article provides clinical application of pelvic floor muscle rehabilitation using biofeedback as a technique to enhance pelvic floor muscle training.

  10. Ultrasound Imaging of the Pelvic Floor. (United States)

    Stone, Daniel E; Quiroz, Lieschen H


    This article discusses the background and appraisal of endoluminal ultrasound of the pelvic floor. It provides a detailed anatomic assessment of the muscles and surrounding organs of the pelvic floor. Different anatomic variability and pathology, such as prolapse, fecal incontinence, urinary incontinence, vaginal wall cysts, synthetic implanted material, and pelvic pain, are easily assessed with endoluminal vaginal ultrasound. With pelvic organ prolapse in particular, not only is the prolapse itself seen but the underlying cause related to the anatomic and functional abnormalities of the pelvic floor muscle structures are also visualized.

  11. Monitoring Radiographic Brain Tumor Progression

    Full Text Available Determining radiographic progression in primary malignant brain tumors has posed a significant challenge to the neuroncology community. Glioblastoma multiforme (GBM, WHO Grade IV through its inherent heterogeneous enhancement, growth patterns, and irregular nature has been difficult to assess for progression. Our ability to detect tumor progression radiographically remains inadequate. Despite the advanced imaging techniques, detecting tumor progression continues to be a clinical challenge. Here we review the different criteria used to detect tumor progression, and highlight the inherent challenges with detection of progression.

  12. [Functional aspects of pelvic floor surgery]. (United States)

    Wagenlehner, F M E; Gunnemann, A; Liedl, B; Weidner, W


    Pelvic floor dysfunctions are frequently seen in females. The human pelvic floor is a complex structure and heavily stressed throughout female life. Recent findings in the functional anatomy of the pelvic floor have led to a much better understand-ing, on the basis of which enormous improvements in the therapeutic options have arisen. The pelvic floor activity is regulated by three main muscular forces that are responsible for vaginal tension and suspension of the pelvic floor -organs, bladder and rectum. For different reasons laxity in the vagina or its supporting ligaments as a result of altered connective tissue can distort this functional anatomy. A variety of symptoms can derive from these pelvic floor dysfunctions, such as urinary urge and stress incontinence, abnormal bladder emptying, faecal incontinence, obstructive bowel disease syndrome and pelvic pain. Pelvic floor reconstruction is nowadays driven by the concept that in the case of pelvic floor symptoms restoration of the anatomy will translate into restoration of the physiology and ultimately improve the patients' symptoms. The exact surgical reconstruction of the anatomy is there-fore almost exclusively focused on the restoration of the lax pelvic floor ligaments. An exact identification of the anatomic lesions preoperatively is eminently necessary, to allow for an exact anatomic reconstruction with respect to the muscular forces of the pelvic floor.

  13. Synthetic biomaterials for pelvic floor reconstruction. (United States)

    Karlovsky, Matthew E; Kushner, Leslie; Badlani, Gopal H


    Pelvic organ prolapse and stress urinary incontinence increase with age. The increasing proportion of the aging female population is likely to result in a demand for care of pelvic floor prolapse and incontinence. Experimental evidence of altered connective tissue metabolism may predispose to pelvic floor dysfunction, supporting the use of biomaterials, such as synthetic mesh, to correct pelvic fascial defects. Re-establishing pelvic support and continence calls for a biomaterial to be inert, flexible, and durable and to simultaneously minimize infection and erosion risk. Mesh as a biomaterial has evolved considerably throughout the past half century to the current line that combines ease of use, achieves good outcomes, and minimizes risk. This article explores the biochemical basis for pelvic floor attenuation and reviews various pelvic reconstructive mesh materials, their successes, failures, complications, and management.

  14. Factors affecting pelvic rotation in idiopathic scoliosis (United States)

    Zhao, Yunfei; Qi, Lin; Yang, Jun; Zhu, Xiaodong; Yang, Changwei; Li, Ming


    Abstract Pelvic rotation (PR) is commonly seen in patients with idiopathic scoliosis (IS), but factors contributing to this phenomenon and its relationship with the surgical outcome are not well established. This retrospective study included 85 IS patients in 2 groups: thoracic curve dominance group (group A) and lumbar curve dominance group (group B). Pre- and postoperative PR was measured on standing posteroanterior radiographs by the left/right ratio (L/R ratio) of horizontal distance between the anterior superior iliac spine (ASIS) and the inferior ilium (SI) at the sacroiliac joint on the same side in both groups. Other radiographic data, age, sex, and Risser sign of each patient were recorded to analyze their correlations with PR before and after operation. The patients ranged in age from 10 to 35 years with a mean of 17.0 ± 5.2 years. The mean L/R ratio of PR before operation was 0.99 (0.73–1.40) versus 0.98 (0.87–1.26) after operation. The L/R ration was beyond the range of 1 ± 0.1 (indicating the presence of PR) in 17 (20%) patients before operation and in 14 (16.5%) patients after operation. There was no significant difference in PR between the 2 groups of patients either before (P = 0.468) or after (P = 0.944) surgery. The preoperative PR showed a very low correlation with Risser sign (r = 0.220, P = 0.043), apex vertebral rotation (AVR) in the proximal thoracic curve (r = 0.242, P = 0.026), and AVR in the lumbar curve (r = 0.213, P = 0.049), while the postoperative PR showed a very low correlation with Risser sign (r = −0.341, P = 0.001) and postoperative trunk shift (TS) (r = −0.282, P = 0.009). Multiple stepwise regression analysis showed that preoperative PR was affected by proximal thoracic curve AVR and lumbar curve AVR. There was no significant difference between PR before operation and 2 years after operation. Preoperative PR was mainly correlated with Risser sign and the rotation

  15. [Complex pelvic injury in childhood]. (United States)

    Schmal, H; Klemt, C; Haag, C; Bonnaire, F


    Pelvic disruptions are rare in children caused by the flexible anchoring of bony parts associated with a high elasticity of the skeleton. Portion of pelvic fractures in infants is lower than 5% even when reviewing cases of specialized centers. The part of complex pelvic injuries and multiple injured patients in infants is higher when compared to adults, a fact caused by the more intense forces that are necessary to lead to pelvic disruption in children. Combination of a rare injury and the capability of children to compensate blood loss for a long time may implicate a wrong security and prolong diagnostic and therapeutic procedures--a problem that definitely should be avoided. Three cases were analyzed and established algorithms for treatment of patients matching these special injury-features demonstrated. A good outcome may only be achieved when all components of injury pattern get recognized and treatment is organized following the hierarchy of necessity. Therefore in the time table first life-saving steps have to be taken and then accompanying injuries can be treated that often decisively influence life quality. As seen in our cases unstable and dislocated fractures require open reduction and internal fixation ensuring nerval decompression, stop of hemorrhage and realizing the prerequisite for effective treatment of soft tissue damage. The acute hemorrhagic shock is one of the leading causes of death following severe pelvic injuries. After stabilization of fracture, surgical treatment of soft tissue injuries and intraabdominal bleeding sources the immediate diagnostic angiography possibly in combination with a therapeutic selective embolization is a well established part of the treatment. The aim of complete restitution can only be accomplished by cooperation of several different specialists and consultants in a trauma center.

    Pithon, Matheus Melo; dos Santos, Rogério Lacerda; Sampaio, Gêisa Aiane de Morais; de Meneses, Izaura Helena Chaves; Coqueiro, Raildo Silva


    The aim of this study was to evaluate the post-treatment anteroposterior and vertical alterations in skeletal Class II malocclusion with different maxillary patterns in patients treated with modified Thurow appliance. Forty-five patients (22 girls and 23 boys) with skeletal Class II and angle SN.GoGn ≤ 35 and different maxillary patterns (n = 15), as follows: retrusive (SNA84°) maxilla; mean age 9 years at pre-treatment (T1) and 9 years and 10 months at post-treatment (T2), were treated with modified Thurow cervical traction appliance, with expander screw and extraoral face bow with 10° to 20° fold in relation to the intraoral arch. Force of 500 gf was applied and use for 12 to 14 h/day, with fortnightly adjustments. Analysis of variance ANOVA followed by post-hoc Tukey and Kruskal-Wallis test, followed by Mann-Whitney were used (α = 5%). In changes obtained from stage T1 to T2, no statistically significant differences were found among the groups Protrusive, normal and retrusive maxilla for the variables SNB, SN.GoGn, 1.NA, overjet, overbite and Class II discrepancy (right and left) (p>0.05). Angular measurements SNA and ANB in the protrusive maxilla group were significantly greater than in the normal and retrusive maxilla groups (p0.05). Within the limits of this study, it may be concluded that the modified Thurow cervical traction appliance was efficient for the correction of skeletal Class II irrespective of the maxillary pattern. The mandible had no significant rotation during treatment.

    Edgar Takao Utino


    Full Text Available OBJECTIVE: Perform radiographic analysis of the use of Transverse Traction Device (DTT with respect to fusion rate in patients submitted to vertebral arthrodesis for degenerative lumbar diseases. METHODS: We selected x-ray images on anteroposterior, lateral and oblique views and with maximum flexion and extension dynamics of 23 patients submitted to posterolateral arthrodesis of the lumbar spine with a minimum follow-up period of six months. The images were evaluated and classified by the Linovitz's system by two spine surgeons. RESULTS: We evaluated the radiographs of 23 patients after the minimum postoperative period of 6 months and of these, 11 have used DTT. With regard to the consolidation rate, seven patients (63.6% in the group of DTT were classified as fusion as well as six patients (50% who were not submitted to the treatment. There was no statistical difference between the groups regarding the consolidation rate. CONCLUSION: The use of transverse traction device in this study showed no significant difference in the rate of consolidation in radiographic evaluation. Studies on the effective participation of this device in the stability of pedicle fixation systems are still lacking in the literature.

  19. Acute abdominal pain in children: usefulness of three-view abdominal radiographs in the emergency department. (United States)

    He, Lulu; Park, Ellen; Vachhani, Neil; Vogelius, Esben; Thupili, Chakradhar; Udayasankar, Unni


    Diagnostic imaging is often an integral component in the workup of a pediatric patient with acute abdominal pain. The purpose of this study was to compare the diagnostic value of a three-view acute abdominal series (AAS) with that of a single supine view (SSV) in children with acute abdominal pain. All subjects aged ≤18 years that underwent an emergency three-view AAS examination for acute abdominal pain at a single urban hospital system were included. Retrospective evaluation of radiological diagnosis, number of radiological images, further imaging, management, and clinical outcomes was performed. "Positive" AAS studies were compared with corresponding SSV images for direct comparison of diagnostic value. Standard nonparametric statistical evaluation was performed. Five hundred forty-one AAS studies were included in the study. Greater than three radiographs were acquired in 29 % (153/541) of the subjects. Two hundred ninety-nine out of 541 AAS studies included a technically adequate SSV of the abdomen and pelvis. Most AAS examinations were categorized as negative (n = 485; 90 %). Of the 56 examinations initially classified as positive, there was no significant statistical difference between diagnostic accuracy between the AAS and SSV on retrospective evaluation. For pediatric subjects with nontraumatic acute abdominal pain, the yield of conventional radiographic study is exceedingly low. If required, a technically adequate single supine anteroposterior (AP) view of the abdomen and pelvis is sufficient for initial radiographic evaluation while reducing unnecessary radiation exposure to the patient.

  20. Pelvic compartment syndrome caused by retroperitoneal hematoma of pelvic fracture

    Institute of Scientific and Technical Information of China (English)

    ZHANG Feng-qi; ZHANG Ying-ze; PAN Jin-she; PENG A-qin; WANG Hui-juan


    @@ Retroperitoneal hematoma is an obligatory complication in pelvic ring fracture.1 In most cases, the bleeding originates from venous vessels of the presacral plexus, small arteries and veins from fracture fragments. External fixation of the pelvis can control blood loss by reducing diastasis and dramatically decreasing the volume of the pelvis. But this tamponade effect can not prevent the presence of hematoma in the adjoining retroperitoneal space. It is well known that complication of retroperitoneal hematoma is infection and sepsis.

    Full Text Available OBJECTIVE: A comparative analysis by applying the criteria of the original classification Ahlbäck in the anteroposterior (AP bipedal knee in extension and anteroposterior (AP monopodal knee in symptomatic knee arthrosis. With this analysis we intend to observe the agreement, any advantage or difference between the incidence and degree of joint involvement between the orthopedic surgeons and radiologists with the referring physician. METHODS: From January 2012 to March 2012, was a prospective study of 60 symptomatic arthrosis knees (60 patients, clinically selected group of outpatient knee and radiographic proposals submitted to the search. Of the 60 patients, 39 were female and 21 male, mean age 64 years (ranging from 50 to 84 years. Of the 60 knees studied, 37 corresponded to the right side and 23 on the left side. Statistical analysis was performed by Kappa statistics, which evaluates the interobserver agreement for qualitative data. RESULTS: According to the scale of Ahlbäck, there was a significant agreement (p < 0.0001 intra-observer in the classification of knee osteoarthritis among the five evaluators. There was a significant agreement (p < 0.0001 with inter-observer referring physician in the incidence of AP monopodal and AP bipedal for the four raters. CONCLUSION: The study found no difference between the incidence in the AP monopodal versus AP bipedal in osteoarthritis of the knee.

  2. TBI lung dose comparisons using bilateral and anteroposterior delivery techniques and tissue density corrections. (United States)

    Bailey, Daniel W; Wang, Iris Z; Lakeman, Tara; Hales, Lee D; Singh, Anurag K; Podgorsak, Matthew B


    This study compares lung dose distributions for two common techniques of total body photon irradiation (TBI) at extended source-to-surface distance calculated with, and without, tissue density correction (TDC). Lung dose correction factors as a function of lateral thorax separation are approximated for bilateral opposed TBI (supine), similar to those published for anteroposterior-posteroanterior (AP-PA) techniques in AAPM Report 17 (i.e., Task Group 29). 3D treatment plans were created retrospectively for 24 patients treated with bilateral TBI, and for whom CT data had been acquired from the head to the lower leg. These plans included bilateral opposed and AP-PA techniques- each with and without - TDC, using source-to-axis distance of 377 cm and largest possible field size. On average, bilateral TBI requires 40% more monitor units than AP-PA TBI due to increased separation (26% more for 23 MV). Calculation of midline thorax dose without TDC leads to dose underestimation of 17% on average (standard deviation, 4%) for bilateral 6 MV TBI, and 11% on average (standard deviation, 3%) for 23 MV. Lung dose correction factors (CF) are calculated as the ratio of midlung dose (with TDC) to midline thorax dose (without TDC). Bilateral CF generally increases with patient separation, though with high variability due to individual uniqueness of anatomy. Bilateral CF are 5% (standard deviation, 4%) higher than the same corrections calculated for AP-PA TBI in the 6 MV case, and 4% higher (standard deviation, 2%) for 23 MV. The maximum lung dose is much higher with bilateral TBI (up to 40% higher than prescribed, depending on patient anatomy) due to the absence of arm tissue blocking the anterior chest. Dose calculations for bilateral TBI without TDC are incorrect by up to 24% in the thorax for 6 MV and up to 16% for 23 MV. Bilateral lung CF may be calculated as 1.05 times the values published in Table 6 of AAPM Report 17, though a larger patient pool is necessary to better

  3. [Sexual dysfunction following pelvic surgery]. (United States)

    Hojo, K


    In male, sexual dysfunction was a common complication that occurred after radical pelvic surgery: radical protectomy, radical cysto-, prostatectomy. Upon the recent pelvic neuroanatomical findings and preservation of these nerves, it is now possible to perform successful cancer operation on the rectum, prostate or bladder with preservation of sexual function in the group of early cancer patients. Depending on the location and severity of these nerve injury, this could result in temporary or permanent erectile and ejaculation dysfunction. In female, the total hysterectomy for cervical cancer sacrifices or injuries the faculty of pregnancy or sexual intercourse. The oophorectomies causes a deficiency of female hormones. But recently the numbers of patients with a small or early stages cancer of uterine or ovary are increasing and we have become to be able to save the functions of these organs in many patients well with minimum local excision or partial resection of them.

  4. Obesity and pelvic floor dysfunction. (United States)

    Ramalingam, Kalaivani; Monga, Ash


    Obesity is associated with a high prevalence of pelvic floor disorders. Patients with obesity present with a range of urinary, bowel and sexual dysfunction problems as well as uterovaginal prolapse. Urinary incontinence, faecal incontinence and sexual dysfunction are more prevalent in patients with obesity. Uterovaginal prolapse is also more common than in the non-obese population. Weight loss by surgical and non-surgical methods plays a major role in the improvement of these symptoms in such patients. The treatment of symptoms leads to an improvement in their quality of life. However, surgical treatment of these symptoms may be accompanied by an increased risk of complications in obese patients. A better understanding of the mechanism of obesity-associated pelvic floor dysfunction is essential.

    Bredella, Miriam A.; Azevedo, Debora C.; Oliveira, Adriana L.; Simeone, Frank J.; Chang, Connie Y.; Torriani, Martin [Massachusetts General Hospital, Department of Radiology, Musculoskeletal Imaging and Intervention, Boston, MA (United States); Stubbs, Allston J. [Wake Forest University School of Medicine, Department of Orthopedic Surgery, Division of Sports Medicine, Winston-Salem, NC (United States)


    To assess MRI measures to quantify pelvic morphology that may predispose to ischiofemoral impingement (IFI). We hypothesized that patients with IFI have a wider interischial distance and an increased femoral neck angle compared with normal controls. The study was IRB-approved and complied with HIPAA guidelines. IFI was diagnosed based on clinical findings (hip or buttock pain) and ipsilateral edema of the quadratus femoris muscle on MRI. Control subjects did not report isolated hip/buttock pain and underwent MRI for surveillance of neoplasms or to exclude pelvic fractures. Two MSK radiologists measured the ischiofemoral (IF) and quadratus femoris (QF) distance, the ischial angle as a measure of inter-ischial distance, and the femoral neck angle. The quadratus femoris muscle was evaluated for edema. Groups were compared using ANOVA. Multivariate standard least-squares regression modeling was used to control for age and gender. The study group comprised 84 patients with IFI (53 ± 16 years, 73 female, 11 male) and 51 controls (52 ± 16 years, 33 female, 18 male). Thirteen out of 84 patients (15 %) had bilateral IFI. Patients with IFI had decreased IF and QF distance (p < 0.0001), increased ischial angle (p = 0.004), and increased femoral neck angle (p = 0.02) compared with controls, independent of age and gender. Patients with IFI have increased ischial and femoral neck angles compared with controls. These anatomical variations in pelvic morphology may predispose to IFI. MRI is a useful method of not only assessing the osseous and soft-tissue abnormalities associated with IFI, but also of quantifying anatomical variations in pelvic morphology that can predispose to IFI.

    To evaluate the feasibility of using chest radiography to differentiate between three different etiologies of pulmonary edema. Plain chest radiographs of 77 patients, who were clinically confirmed as having pulmonary edema, were retrospectively reviewed. The patients were classified into three groups : group 1 (cardiogenic edema : n = 35), group 2 (renal pulmonary edema : n = 16) and group 3 (permeability edema : n = 26). We analyzed the radiologic findings of air bronchogram, heart size, peribronchial cuffing, septal line, pleural effusion, vascular pedicle width, pulmonary blood flow distribution and distribution of pulmonary edema. In a search for radiologic findings which would help in the differentiation of these three etiologies, each finding was assessed. Cardiogenic and renal pulmonary edema showed overlapping radiologic findings, except for pulmonary blood flow distribution. In cardiogenic pulmonary edema (n=35), cardiomegaly (n=29), peribronchial cuffing (n=29), inverted pulmonary blood flow distribution (n=21) and basal distribution of edema (n=20) were common. In renal pulmonary edema (n=16), cardiomegaly (n=15), balanced blood flow distribution (n=12), and central (n=9) or basal distribution of edema (n=7) were common. Permeability edema (n=26) showed different findings. Air bronchogram (n=25), normal blood flow distribution (n=14) and peripheral distribution of edema (n=21) were frequent findings, while cardiomegaly (n=7), peribronchial cuffing (n=7) and septal line (n=5) were observed in only a few cases. On plain chest radiograph, permeability edema can be differentiated from cardiogenic or renal pulmonary edema. The radiographic findings which most reliably differentiated these two etiologies were air bronchogram, distribution of pulmonary edema, peribronchial cuffing and heart size. Only blood flow distribution was useful for radiographic differentiation of cardiogenic and renal edema.

    The purpose of this study was to obtain information on the clinical and radiographic features of the odontomas in the jaws. For this study, the authors examined and analyzed the clinical records and radiographs of 119 patients who had lesion of odontoma diagnosed by clinical and radiographic examinations. The obtained results were as follows: 1. Odontoma occurred the most frequently in the 2nd decade (45.4%) and occurred more frequently in males (60.5%) than in females (39.5%). 2. The most common clinical symptom was the delayed eruption of the teeth (34.2%). 3. The type of lesions was mainly observed as compound odontoma (80.8%), and internal pattern of the complex odontoma was unevenly radiopaque (73.9%). 4. The compound odontoma frequently occurred in anterior portion of the maxilla (57.7%) and mandible (30.9%), and complex odontoma frequently occurred in anterior portion of maxilla (34.8%) and posterior portion of mandible (30.5%). 5. The effects on adjacent teeth were impaction of teeth (71.7%) and prolonged retention of deciduous teeth (31.7%). 6. The impaction of the teeth occurred in anterior portion of maxilla (44.2%) amd mandible (19.2%), but root resorption of the adjacent teeth were not seen. 7. The boundary to adjacent structure was well-defined , the lesions appear as radiopaque mass with radiolucent rim.

  15. [Functional anatomy of the pelvic floor]. (United States)

    Yiou, René; Delmas, Vincent


    The pelvic floor is the support of the pelvic viscera. The levator ani muscle (LA) with its two bundles (pubo- and iliococcygeus) is the major component of this pelvic floor. LA is formed essentially by type I fibers (slow twitch, with high oxidative capability and presence of slow myosin) as in postural muscles. The aerobic metabolism makes LA fragile to excentric contraction and to mitochondrial dysfunction. The innervation of the pelvic floor comes from the 2nd, 3rd, 4th anterior sacral roots; denervation affects pelvic dynamism. Perineum includes the musculofascial structures under the LA: ventrally the striated sphincter of urethra and the ischiocavernosus and bulbospongiosus, caudally the fatty tissue filling the ischioanal fossa. Pelvic fascia covers the muscles ; it presents reinforcements : the uterosacral and cardinal ligaments, the arcus tendineus fascia pelvis (ATFP) and the arcus tendineus levator ani (ATLA). The pelvis statics is supported by the combined action of all this anatomical structures anteriorly forming the perineal "hammock," medially the uterosacral and cardinal ligaments, posteriorly the rectovaginal fascia and the perineal body. The angles formed by the pelvic viscera with their evacuation ducts participate to the pelvic statics. During the pelvic dynamics the modification of these angles expresses the action of the musculofascial structures.

[Kuopio University Hospital, Department of Clinical Radiology, Kuopio (Finland); Hyttinen, Mika M. [University of Eastern Finland, Institute of Biomedicine, Anatomy, Kuopio (Finland); Arokoski, Jari P.A. [Kuopio University Hospital, Department of Physical and Rehabilitation Medicine, Kuopio (Finland)


    To determine the number of participants required in controlled clinical trials investigating the progression of osteoarthritis (OA) of the hip as evaluated by the joint space width (JSW) on radiographs and to evaluate the reproducibility of the JSW measurement methods. Anteroposterior radiographs of hip were taken from 13 healthy volunteers and from 18 subjects with radiographic hip OA. The reproducibility of the JSW was determined from four segments using digital caliper measurements performed on film radiographs and using semiautomatic computerized image analysis of digitized images. Pearson correlation coefficient, coefficient of variability [CV (%)], and sample size values were calculated. It was found that 20 was a typical number of patients for a sufficiently powered study. The highest sample size was found in subjects with OA in the lateral segment. The reproducibility of the semiautomatic computerized method was not significantly better than the digital caliper method. The number of study subjects required to detect a significant joint space narrowing in follow-up studies is influenced by the baseline hip joint OA severity. The JSW measurements with computerized image analysis did not improve the reproducibility and thus performing JSW measurements with a digital caliper is acceptable. (orig.)

  20. The sagittal pelvic thickness: a determining parameter for the regulation of the sagittal spinopelvic balance. (United States)

    Jean, Legaye


    Objective. To propose and validate a dimensional parameter, the sagittal pelvic thickness (SPT) (distance between the middle point of the upper sacral plate and the femoral heads axis, expressed as a ratio with the length of the upper plate of S1: (SPT/S1) for the analysis of the sagittal balance of the pelvispinal unit. Methods. The parameters were analysed on standing radiographic imaging and compared for normal, low back pain, children, and spondylolysis cases. Results. Values of SPT/S1 were observed significantly higher in high grade spondylolysis populations and in children (3,5 and 3,7) than in normal population (3,3). A geometrical connection with the classical angular parameters validated SPT/S1. Conclusion. SPT/S1 was considered reflecting the lever arm of action of spinopelvic muscles and ligaments and describing the ability of a subject to compensate a sagittal unbalance. It was proposed as an anatomical and functional pelvic parameter.

    Grappiolo, Guido; Loppini, Mattia; Longo, Umile Giuseppe; Traverso, Francesco; Mazziotta, Giuseppe; Denaro, Vincenzo


    Fifty-five hips undergoing acetabular reconstruction with trabecular metal (TM)-coated cup and TM augments were reviewed at an average follow up of 53.7 months (36-91). Bony defects were Paprosky type IIIA in 42 and type IIIB without pelvic discontinuity in 13 hips. The average HHS increased from 40 (27-52) preoperatively to 90.5 (61-100) postoperatively (P<0.0001). Four (7.3%) of 55 hips underwent acetabular components revision: three cases of loosening (5.4%), and one of recurrent instability (1.8%) were reported. Survival rate at 2 and 5 years was 96.4% and 92.8%. In conclusion, the use of TM-coated cups and augments could be considered an effective management of Paprosky type III defects without pelvic discontinuity providing good clinical and radiographic outcomes in the mid term.

  5. Survival Following Rectal Impalement through the Pelvic, Abdominal, and Thoracic Cavities: A Case Report

    Directory of Open Access Journals (Sweden)

    Michael Moncure


    Full Text Available Impalement injuries are a unique form of penetrating trauma and are typically associated with a fall onto the object (Steele, 2006. We present the case of a 45-year-old man who reportedly slipped in his bathtub and fell onto a broomstick. Radiographic examination revealed a slender mass extending from his rectum to the right side of his neck. A review of English literature suggests that this is the second reported case in the last 100 years describing the successful management of an impalement injury traversing the pelvic, abdominal, and thoracic cavities. The management of this case is described.

    Mayilvahanan N


    Full Text Available Background: Pelvic tumours present a complex problem. It is difficult to choose between limb salvage and hemipelvectomy. Method: Forty three patients of tumours of pelvis underwent limb salvage resection with reconstruction in 32 patients. The majority were chondrosarcomas (20 cases followed by Ewing sarcoma. Stage II B was the most common stage in malignant lesions and all the seven benign lesions were aggressive (B3. Surgical margins achieved were wide in 31 and marginal in 12 cases. Ilium was involved in 51% of cases and periacetabular involvement was seen in 12 patients. The resections done were mostly of types I &II of Enneking′s classification of pelvic resection. Arthrodesis was attempted in 24 patients. Customized Saddle prosthesis was used in seven patients and no reconstruction in 12 patients. Adjuvant chemotherapy was given to all high-grade malignant tumours, combined with radiotherapy in 7 patients. Results: With a mean follow up of 48.5 months and one patient lost to follow up, the recurrence rate among the evaluated cases was 16.6%. Oncologically, 30 patients were continuously disease free with 7 local recurrences and 4 deaths due to disseminated disease and 2 patients died of other causes. During the initial years, satisfactory functional results were achieved with prosthetic replacement. Long-term functional result of 36 patients who were alive at the time of latest follow up was satisfactory in 75% who underwent arthrodesis and in those where no reconstruction was used. We also describe a method of new classification of pelvic resections that clarifies certain shortcomings of the previous systems of classification. Conclusion: Selection of a procedure depends largely on the patient factors, the tumour grade, the resultant defect and the tissue factors. Resection with proper margins gives better functional and oncological results

  7. Imaging of male pelvic trauma. (United States)

    Avery, Laura L; Scheinfeld, Meir H


    Prompt imaging plays an important role in the evaluation of male pelvic soft tissue trauma. Using appropriate imaging modalities, with optimization of contrast administration when appropriate, is essential for accurate diagnosis. Traumatic bladder rupture, either extraperitoneal or intraperitoneal, is diagnosed with high accuracy using computed tomography cystography. Suspicion of urethral injury warrants evaluation with retrograde urethrography to evaluate for the presence of injury and injury location. Early identification of laceration of the testicular tunica albuginea is essential. Understanding both normal penile anatomy and the imaging appearance of corpus rupture (as opposed to a hematoma) is imperative for proper diagnosis and management.

  10. Progression of Hip Displacement during Radiographic Surveillance in Patients with Cerebral Palsy (United States)


    Progression of hip displacement is common in patients with cerebral palsy (CP). We aimed to investigate the rate of progression of hip displacement in patients with CP by assessing changes in radiographic indices according to Gross Motor Function Classification System (GMFCS) level during hip surveillance. We analyzed the medical records of patients with CP aged < 20 years who underwent at least 6 months interval of serial hip radiographs before any surgical hip intervention, including reconstructive surgery. After panel consensus and reliability testing, radiographic measurements of migration percentage (MP), neck-shaft angle (NSA), acetabular index (AI), and pelvic obliquity (PO) were obtained during hip surveillance. For each GMFCS level, annual changes in radiographic indices were analyzed and adjusted for affecting factors, such as sex, laterality, and type of CP. A total of 197 patients were included in this study, and 1,097 radiographs were evaluated. GMFCS classifications were as follows: 100 patients were level I-III, 48 were level IV, and 49 were level V. MP increased significantly over the duration of hip surveillance in patients with GMFCS levels I-III, IV, and V by 0.3%/year (P < 0.001), 1.9%/year (P < 0.001), and 6.2%/year (P < 0.001), respectively. In patients with GMFCS level IV, NSA increased significantly by 3.4°/year (P < 0.001). Our results suggest that periodic monitoring and radiographic hip surveillance is warranted for patients with CP, especially those with GMFCS level IV or V. Furthermore, physicians can predict and inform parents or caregivers regarding the progression of hip displacement in patients with CP. PMID:27366015

  12. Radiographic survey of perlite workers. (United States)

    Cooper, W C


    Chest roentgenograms of 240 perlite workers employed for 1 to 23 years in the industry, showed no evidence of pneumoconiosis associated with perlite exposures. One individual, found to have simple pneumoconiosis, and one found to have complicated pneumoconiosis, had formerly been diatomaceous earth workers. Since only 28 of the men had been in the industry over 15 years and only seven for 20 years or more, continued surveillance is essential to make sure that there are no effects with more prolonged exposures. Studies of pulmonary function of the individuals who have had relatively long exposures are needed to supplement radiographic evidence.

  15. Disc height and anteroposterior translation in fused and adjacent segments after lumbar spine fusion

    Directory of Open Access Journals (Sweden)

    Frobin, Wolfgang


    Full Text Available In a series of 46 patients the effects of spinal fusion upon intervertebral height and sagittal alignment in operated and non-operated segments were retrospectively evaluated on digitized radiographs. Data was compared with age- and gender-normalized standard values. The objective was to evaluate the influence of different types of spine fusions primarily upon adjacent segments, particularly in terms of degeneration and sagittal profile of the lumbar spine. Incidence of adjacent segment degeneration (ASD is still highly controversial. However, not every degeneration adjacent to spinal fusion must be caused by the fusion and responsibility of the fusion for ASD may vary with its range and type. Distortion Corrected Roentgen Analysis (DCRA was utilized. DCRA is a proven valid, reliable, observer-independent, and accurate tool for assessment of these parameters over time and in comparison with "normal" cohorts. With this method the exact posture of the patients needs not to be known.There was little evidence for serious fusion-related ASD within an average of 40 months follow-up. No difference could be detected for rigid vs. non-rigid fusion and instrumented vs. non-instrumented techniques. Temporary postoperative distraction effects could be detected in operated and non-operated segments. Absolute preoperative values for intervertebral height and vertebral slip were age-related. Retrospectively, the choice of segments for fusion was clearly based upon radiological criteria. Thus we conclude that radiological parameters have an obvious clinical relevance for decision-making and need to be quantified. Within the limitations of this pilot study, true fusion related ASD seems to be infrequent.

    Institute of Scientific and Technical Information of China (English)

    张宏其; 楚戈; 卡哈尔·艾肯木


    BACKGROUND: Lumbar spondylolisthesis is commonly confirmed by using flexion and extension radiographs, and the severity is determined through slip distance and slip angle.OBJECTIVE: To define and demonstrate the presence of "vertical instability" in lumbar spondylolisthesis, and to determine the most useful radiographic views for clinical purposes and analysis of the surgical strategy.METHODS: Lateral and flexion extension radiographs of the lumbosacral spine in 37 patients with spondylolisthesis taken in standing and recumbent positions and under pelvic traction in the prone or supine positions were suitable for analysis. The changes in disc area, intervertebral kyphotic slip angle, and amount of anteroposterior shift (olisthesis) were measured from the radiographs using a computer digitizer.RESULTS AND CONCLUSION: Maximum slip angle, maximum olisthesis, and minimum normalized disc area were found in patients under erect flexion. Conversely, prone traction and recumbent extension produced minimum slip angle, whereas the lowest anteroposterior shifts were seen in patients under prone and supine traction. Prone traction also resulted in a significantly larger normalized disc area than any other posture. The change in kyphotic slip angle between erect flexion and prone traction was correlated with the change in normalized olisthesis and disc area. Erect flexion and prone traction radiographs represent the extremes of subluxation and reduction of the olisthesis, respectively, and the change in olisthesis seen between these extremes is correlated with the change in disc area and the intervertebral slip angle. Vertical laxity of the affected functional spinal unit resulting from disc degeneration produces laxity in the ligaments and disc anulus, allowing olisthetic motion. Restoration of disc height in turn restores tension to the soft tissues around the disc and results in a spontaneous reduction of the subluxation. Restoration and maintenance of disc height with a

[Penn State Hershey Medical Center, Department of Radiology, Hershey, PA (United States); Ha, Alice S. [University of Washington, Department of Radiology, Box 354755, Seattle, WA (United States)


    Total elbow arthroplasty (TEA) is becoming a popular alternative to arthrodesis for patients with end-stage elbow arthrosis and comminuted distal humeral fractures. Prior outcome studies have primarily focused on surgical findings. Our purpose is to determine the radiographic outcome of TEA and to correlate with clinical symptoms such as pain. This is an IRB-approved retrospective review from 2005 to 2015 of all patients with semiconstrained TEA. All available elbow radiographs and clinical data were reviewed. Data analysis included descriptive statistics and Kaplan-Meier survival curves for radiographic and clinical survival. A total of 104 total elbow arthroplasties in 102 patients were reviewed; 75 % were in women and the mean patient age was 63.1 years. Mean radiographic follow-up was 826 days with average of four radiographs per patient. Seventy TEAs (67 %) developed radiographic complications, including heterotopic ossification (48 %), perihardware lucency (27 %), periprosthetic fracture (23 %), hardware subluxation/dislocation (7 %), polyethylene wear (3 %), and hardware fracture/dislodgement (3 %); 56 patients (55 %) developed symptoms of elbow pain or instability and 30 patients (30 %) underwent at least one reoperation. In patients with radiographic complications, 66 % developed elbow pain, compared to 19 % of patients with no radiologic complications (p = 0.001). Of the patients with radiographic complications, 39 % had at least one additional surgery compared to 0 % of patients without radiographic complications (p = 0.056). Radiographic complications are common in patients after total elbow arthroplasty. There is a strong positive association between post-operative radiographic findings and clinical outcome. Knowledge of common postoperative radiographic findings is important for the practicing radiologist. (orig.)

  18. A radiographic analysis of implant component misfit.

    LENUS (Irish Health Repository)

    Sharkey, Seamus


    Radiographs are commonly used to assess the fit of implant components, but there is no clear agreement on the amount of misfit that can be detected by this method. This study investigated the effect of gap size and the relative angle at which a radiograph was taken on the detection of component misfit. Different types of implant connections (internal or external) and radiographic modalities (film or digital) were assessed.

  19. Prognostic radiographic aspects of spondylolisthesis

    Saraste, H.; Brostroem, L.A.; Aparisi, T.


    A series of 202 patients (133 men, 69 women) with lumbar spondylolysis were examined radiographically on two occasions, first at the time of diagnosis and later at a follow-up, after an observation period of 20 years or more. The films from patients in groups without and with moderate and severe olisthesis were evaluated with respect to variables describing lumbosacral lordosis, wedging of the spondylolytic vertebra, lengths of the transverse processes and iliolumbar ligaments, disk height, progression of slipping, and influence on measured olisthesis of lumbar spine flexion and extension at the radiographic examination. The evaluation was made with special attention to possible signs which could be predictive for the prognosis of vertebral slipping. Progression of slipping did not differ between patients diagnosed as adults or adolescents. Reduction of disk height was correlated to the degree of slipping present at the initial examination and to the progression of olisthesis. Flexion and extension of the lumbar spine did not modify the degree of olisthesis. Data concerning the lengths of the transverse processes and the iliolumbar ligaments, and lumbar lordosis, cannot be used for prognostic purposes. The lumbar index reflecting the degree of wedge deformity of the spondylolytic vertebra was shown to be the only variable of prognostic value for the development of vertebral slipping.

  1. Total pelvic floor ultrasound for pelvic floor defaecatory dysfunction: a pictorial review. (United States)

    Hainsworth, Alison J; Solanki, Deepa; Schizas, Alexis M P; Williams, Andrew B


    Total pelvic floor ultrasound is used for the dynamic assessment of pelvic floor dysfunction and allows multicompartmental anatomical and functional assessment. Pelvic floor dysfunction includes defaecatory, urinary and sexual dysfunction, pelvic organ prolapse and pain. It is common, increasingly recognized and associated with increasing age and multiparity. Other options for assessment include defaecation proctography and defaecation MRI. Total pelvic floor ultrasound is a cheap, safe, imaging tool, which may be performed as a first-line investigation in outpatients. It allows dynamic assessment of the entire pelvic floor, essential for treatment planning for females who often have multiple diagnoses where treatment should address all aspects of dysfunction to yield optimal results. Transvaginal scanning using a rotating single crystal probe provides sagittal views of bladder neck support anteriorly. Posterior transvaginal ultrasound may reveal rectocoele, enterocoele or intussusception whilst bearing down. The vaginal probe is also used to acquire a 360° cross-sectional image to allow anatomical visualization of the pelvic floor and provides information regarding levator plate integrity and pelvic organ alignment. Dynamic transperineal ultrasound using a conventional curved array probe provides a global view of the anterior, middle and posterior compartments and may show cystocoele, enterocoele, sigmoidocoele or rectocoele. This pictorial review provides an atlas of normal and pathological images required for global pelvic floor assessment in females presenting with defaecatory dysfunction. Total pelvic floor ultrasound may be used with complementary endoanal ultrasound to assess the sphincter complex, but this is beyond the scope of this review.

    Tércio Henrique Soares de Farias


    Full Text Available OBJECTIVE: To ascertain the geometry of the femur in the Brazilian population by means of a radiographic study and to correlate the values with regard to sex and right/left side.METHODS: Five hundred anteroposterior radiographs of the pelvis of skeletally mature patients (250 of each sex who did not present any osteoarthrosis, fractures or tumoral or infectious lesions were analyzed. The length and width of the femoral neck, length of the femoral axis, neck-shaft angle and femoral offset were measured.RESULTS: The following means were observed: 36.54 mm for the length of the femoral neck; 37.48 mm for the width of the femoral neck; 108.42 mm for the length of the femoral axis; 130.47° for the neck-shaft angle; and 44.4 mm for the femoral offset.CONCLUSION: The mean values for the main measurements on the proximal femur in Brazilians differed from those of previous studies. It could also be shown that there was a statistically significant mean difference between men and women for all the variables, both on the left and on the right side, and that the men had greater means than the women.

    Georgios A Stylianides

    Full Text Available The purpose of this study was to determine how pelvic morphology, body posture, and standing balance variables of scoliotic girls differ from those of able-bodied girls, and to classify neuro-biomechanical variables in terms of a lower number of unobserved variables. Twenty-eight scoliotic and twenty-five non-scoliotic able-bodied girls participated in this study. 3D coordinates of ten anatomic body landmarks were used to describe pelvic morphology and trunk posture using a Flock of Birds system. Standing balance was measured using a force plate to identify the center of pressure (COP, and its anteroposterior (AP and mediolateral (ML displacements. A multivariate analysis of variance (MANOVA was performed to determine differences between the two groups. A factor analysis was used to identify factors that best describe both groups. Statistical differences were identified between the groups for each of the parameter types. While spatial orientation of the pelvis was similar in both groups, five of the eight trunk postural variables of the scoliotic group were significantly different that the able-bodied group. Also, five out of the seven standing balance variables were higher in the scoliotic girls. Approximately 60% of the variation is supported by 4 factors that can be associated with a set of variables; standing balance variables (factor 1, body posture variables (factor 2, and pelvic morphology variables (factors 3 and 4. Pelvic distortion, body posture asymmetry, and standing imbalance are more pronounced in scoliotic girls, when compared to able-bodied girls. These findings may be beneficial when addressing balance and ankle proprioception exercises for the scoliotic population.

    Sen Ramesh


    Full Text Available Background: The behavior of pelvic ring fractures in the long run has been very sparsely studied. The purpose of this study is to assess the long-term outcome of pelvic ring fractures. Materials and Methods: A total of 24 patients with pelvic ring fractures, not involving the acetabulum, were followed up for an average duration of 33 months (range 24-49 months. The clinicoradiological assessment was done using the pelvic scoring system adapted from Cole et al. Parameters assessed included sacroiliac (SI joint involvement and, among SI joint injuries, the presence of a fracture disruption and the degree of displacement. Results: Pain and limp were present in 13 patients (54.2% each and residual working disability in 9 patients (37.5%. The overall Cole′s pelvic score was 31.3 ± 7.02 of a total score of 40. The average pelvic score in patients with SI disruption was 29.2 ± 6.75; much lower than patients without SI disruption with an average score of 34.9 ± 6.25 reaching statistical significance. The pelvic score among patients with a displacement ≤10 mm was 33.0 ± 3.92 and with a displacement> 10 mm 25.88 ± 7.14. The difference was statistically significant. Conclusions: Pelvic ring injuries can lead to long term problems significantly. The involvement of the SI joint affects the long-term outcome adversely, more so if the residual displacement is> 10 mm. The pelvic scoring system is comprehensive and depicts subtle differences in the outcome, which the individual parameters of the assessment fail to show.

  5. Three-dimensional Ultrasound Appearance of Pelvic Floor in Nulliparous Women and Pelvic Organ Prolapse Women

    Directory of Open Access Journals (Sweden)

    Tao Ying, Qin Li, Lian Xu, Feifei Liu, Bing Hu


    Full Text Available The present study investigated the morphology and structure of pelvic floor in 50 nulliparous and 50 pelvic organ prolapse (POP women using translabial three-dimensional (3D ultrasound. The levator hiatus in POP women was significantly different from that in nullipara women. In POP women, the size of pelvic floor increased, with a circular shape, and the axis of levator hiatus departed from the normal position in 36 (72% cases. The puborectalis was avulsed in 18 (36% cases and the pelvic organs arranged abnormally in 23 (46% cases. In summary, 3D ultrasound is an effective tool to detect the pelvic floor in POP women who presented with abnormalities in the morphology and structure of pelvic floor.

  6. [Patients with hemodynamic unstable pelvic fractures in extremis: pelvic packing or angiography?]. (United States)

    Liñán-Padilla, A; Giráldez-Sánchez, M Á; Serrano-Toledano, D; Lázaro-Gonzálvez, A; Cano-Luís, P


    The multidisciplinary management of patients with pelvic trauma has improved prognosis, but mortality is still very high. The appropriate treatment strategy remains controversial, especially regarding the control of bleeding in patients whose clinical situation is extreme by using angiography or pelvic packing. We propose using a tool of evidence-based medicine (CAT) the benefit of the completion of pelvic packing in relation to a specific clinical question from a specific situation. What is best for the management of bleeding, extraperitoneal pelvic packing or angiography, in patients with hemodynamically unstable pelvic fracture in extremis? From this study we can conclude that angiography may improve control of bleeding in patients with arterial bleeding and hemodynamically stable but the packing has priority in patients with pelvic fractures and hemodynamic instability.

  8. Informed Consent for Reconstructive Pelvic Surgery. (United States)

    Alam, Pakeeza; Iglesia, Cheryl B


    Informed consent is the process in which a patient makes a decision about a surgical procedure or medical intervention after adequate information is relayed by the physician and understood by the patient. This process is critical for reconstructive pelvic surgeries, particularly with the advent of vaginal mesh procedures. In this article, we review the principles of informed consent, the pros and cons of different approaches in reconstructive pelvic surgery, the current legal issues surrounding mesh use for vaginal surgery, and tips on how to incorporate this information when consenting patients for pelvic floor surgery.

    Ahn, Hyung Kyu [Department of Oral Radiology, College of Dentistry, Seoul National University, Seoul (Korea, Republic of)


    The author studied clinically and radiologically 55 cases which had been diagnosed as odontoma in SNUDH. The obtained results were as follows: 1. In sex distribution, there was no prevalence in both sexes. And the incidence was the highest in the 2nd decade (16 patient, 29%). 2. There were 42 cases of compound odontoma (76%) and 13 cases of complex odontoma (24%). In most cases, compound odontoma was located at the anterior portion (34 cases, 81%) and complex odontoma at the posterior portions (9 cases, 69%). 3. There was no apparent clinical symptom in compound odontoma (83%), but in complex odontoma, 80% of cases show swelling. 4. The adjacent root resorption was not observed in any case. 5. Five cases radiographically diagnosed as cystic odontoma were not confirmed histopathologically.

    Objective: To describe radiographic features of gout that may mimic infection. Design and patients: We report five patients with acute bacterial gout who presented with clinical as well as radiological findings mimicking acute bacterial septic arthritis or osteomyelitis. Three patients had delay in the appropriate treatment with the final diagnosis being established after needle aspiration and identification of urate crystals under polarized light microscopy. Two patients underwent digit amputation for not responding to antibiotic treatment and had histological findings confirming the diagnosis of gout. Conclusion: It is important for the radiologist to be aware of the radiological manifestations of acute gout that can resemble infection in order to avoid inappropriate diagnosis and delay in adequate treatment. The definitive diagnosis should rely on needle aspiration and a specific search for urate crystals. (orig.)

  11. Locally vascularized pelvic accessory spleen. (United States)

    Iorio, F; Frantellizzi, V; Drudi, Francesco M; Maghella, F; Liberatore, M


    Polysplenism and accessory spleen are congenital, usually asymptomatic anomalies. A rare case of polysplenism with ectopic spleen in pelvis of a 67-year-old, Caucasian female is reported here. A transvaginal ultrasound found a soft well-defined homogeneous and vascularized mass in the left pelvis. Patient underwent MRI evaluation and contrast-CT abdominal scan: images with parenchymal aspect, similar to spleen were obtained. Abdominal scintigraphy with 99mTc-albumin nanocolloid was performed and pelvic region was studied with planar scans and SPECT. The results showed the presence of an uptake area of the radiopharmaceutical in the pelvis, while the spleen was normally visualized. These findings confirmed the presence of an accessory spleen with an artery originated from the aorta and a vein that joined with the superior mesenteric vein. To our knowledge, in the literature, there is just only one case of a true ectopic, locally vascularized spleen in the pelvis.

  12. [Aging-related changes of the female pelvic floor]. (United States)

    Scheiner, David; Betschart, Cornelia; Perucchini, Daniele


    The pelvic floor as lower closure of the abdominal cavity has to withstand the abdominal pressure. Meanwhile, the pelvic floor has to allow physiologic functions like micturition, defecation, sexual function and reproduction. But while pregnancy and vaginal delivery damage the pelvic floor directly, chronic stress like caugh, heavy lifting, or obesity lead to a chronic overstraining of the pelvic floor. Aging, structural changes, and possibly estrogen deficiency have a negative impact on the pelvic floor.

    Nonrelaxing pelvic floor dysfunction is not widely recognized. Unlike in pelvic floor disorders caused by relaxed muscles (eg, pelvic organ prolapse or urinary incontinence, both of which often are identified readily), women affected by nonrelaxing pelvic floor dysfunction may present with a broad range of nonspecific symptoms. These may include pain and problems with defecation, urination, and sexual function, which require relaxation and coordination of pelvic floor muscles and urinary and ...

  14. Recognizing myofascial pelvic pain in the female patient with chronic pelvic pain. (United States)

    Pastore, Elizabeth A; Katzman, Wendy B


    Myofascial pelvic pain (MFPP) is a major component of chronic pelvic pain (CPP) and often is not properly identified by health care providers. The hallmark diagnostic indicator of MFPP is myofascial trigger points in the pelvic floor musculature that refer pain to adjacent sites. Effective treatments are available to reduce MFPP, including myofascial trigger point release, biofeedback, and electrical stimulation. An interdisciplinary team is essential for identifying and successfully treating MFPP.

    Aufderheide, M.; Stone, D.; VonWittenau, A.


    In this paper, the authors describe their work on developing quantitatively accurate radiographic simulation and analysis tools for ASCI hydro codes. they have extended the ability of HADES, the code which simulates radiography through a mesh, to treat the complex meshes used in ASCI calculations. The ultimate goal is to allow direct comparison between experimental radiographs and full physics simulated radiographs of ASCI calculations. They describe the ray-tracing algorithm they have developed for fast, accurate simulation of dynamic radiographs with the meshes used in ALE3D, an LLNL ASCI code. Spectral effects and material compositions are included. In addition to the newness of the mesh types, the distributed nature of domain decomposed problems requires special treatment by the radiographic code. Because of the size of such problems, they have parallelized the radiographic simulation, in order to have quick turnaround time. presently, this is done using the domain decomposition from the hydro code. They demonstrate good parallel scaling as the size of the problem is increased. They show a comparison between an experimental radiograph of a high explosive detonation and a simulated radiograph of an ALE3D calculation. They conclude with a discussion of future work.

  1. Structural Dynamics and Epigenetic Modifications of Hoxc Loci along the Anteroposterior Body Axis in Developing Mouse Embryos

    Directory of Open Access Journals (Sweden)

    Hyehyun Min, Ji-Yeon Lee, Myoung Hee Kim


    Full Text Available Hox genes are organized as clusters and specify regional identity along the anteroposterior body axis by sequential expression at a specific time and region during embryogenesis. However, the precise mechanisms underlying the sequential spatio-temporal, collinear expression pattern of Hox genes are not fully understood. Since epigenetic modifications such as chromatin architecture and histone modifications have become crucial mechanisms for highly coordinated gene expressions, we examined such modifications. E14.5 mouse embryos were dissected into three parts along the anteroposterior axis: brain, trunk-anterior, and trunk-posterior. Then, structural changes and epigenetic modifications were analyzed along the Hoxc cluster using chromosome conformation capture and chromatin immunoprecipitation-PCR methods. Hox non-expressing brain tissues had more compact, heterochromatin-like structures together with the strong repressive mark H3K27me3 than trunk tissues. In the trunk, however, a more loose euchromatin-like topology with a reduced amount of H3K27me3 modifications were observed along the whole cluster, regardless of their potency in gene activation. The active mark H3K4me3 was rather closely associated with the collinear expression of Hoxc genes; at trunk-anterior tissues, only 3' anterior Hoxc genes were marked by H3K4me3 upon gene activation, whereas whole Hoxc genes were marked by H3K4me3 and showed expression in trunk-posterior tissues. Altogether, these results indicated that loosening of the chromatin architecture and removing H3K27me3 were not sufficient for, but rather the concomitant acquisition of H3K4me3 drove the collinear expression of Hoxc genes.

    To describe the chest radiographic findings of acute paraquat poisoning. 691 patients visited the emergency department of our hospital between January 2006 and October 2012 for paraquat poisoning. Of these 691, we identified 56 patients whose initial chest radiographs were normal but who developed radiographic abnormalities within one week. We evaluated their radiographic findings and the differences in imaging features based on mortality. The most common finding was diffuse consolidation (29/56, 52%), followed by consolidation with linear and nodular opacities (18/56, 32%), and combined consolidation and pneumomediastinum (7/56, 13%). Pleural effusion was noted in 17 patients (30%). The two survivors (4%) showed peripheral consolidations, while the 54 patients (96%) who died demonstrated bilateral (42/54, 78%) or unilateral (12/54, 22%) diffuse consolidations. Rapidly progressing diffuse pulmonary consolidation was observed within one week on follow-up radiographs after paraquat ingestion in the deceased, but the survivors demonstrated peripheral consolidation.

  4. Pelvic Surgical Site Infections in Gynecologic Surgery

    Directory of Open Access Journals (Sweden)

    Mark P. Lachiewicz


    Full Text Available The development of surgical site infection (SSI remains the most common complication of gynecologic surgical procedures and results in significant patient morbidity. Gynecologic procedures pose a unique challenge in that potential pathogenic microorganisms from the skin or vagina and endocervix may migrate to operative sites and can result in vaginal cuff cellulitis, pelvic cellulitis, and pelvic abscesses. Multiple host and surgical risk factors have been identified as risks that increase infectious sequelae after pelvic surgery. This paper will review these risk factors as many are modifiable and care should be taken to address such factors in order to decrease the chance of infection. We will also review the definitions, microbiology, pathogenesis, diagnosis, and management of pelvic SSIs after gynecologic surgery.

  6. Postoperative pelvic pain: An imaging approach. (United States)

    Farah, H; Laurent, N; Phalippou, J; Bazot, M; Giraudet, G; Serb, T; Poncelet, E


    Postoperative pelvic pain after gynecological surgery is a readily detected but unspecific sign of complication. Imaging as a complement to physical examination helps establish the etiological diagnosis. In the context of emergency surgery, vascular, urinary and digestive injuries constitute the most frequent intraoperative complications. During the follow-up of patients who had undergone pelvic surgery, imaging should be performed to detect recurrent disease, postoperative fibrosis, adhesions and more specific complications related to prosthetic material. Current guidelines recommend using pelvic ultrasonography as the first line imaging modality whereas the use of pelvic computed tomography and/or magnetic resonance imaging should be restricted to specific situations, depending on local availability of equipment and suspected disease.

    Wiesner, W.; Bongartz, G. [Inst. of Diagnostic Radiology University Hospital Basel (Switzerland); Stoffel, F. [Inst. of Urology, University Hospital Basel (Switzerland)


    Two patients presented with ureteric obstruction, and voiding symptoms and constipation, respectively, and were examined by means of intravenous urography and computed tomography. One patient was additionally examined by means of MR tomography. After CT (performed in both patients) and MRT (performed in one patient) had shown a diffuse, contrast-enhancing, infiltrating process in the small pelvis with infiltration of adjacent organs and vessels, surgical biopsy proved the diagnosis of idopathic pelvic fibrosis. Extension of retroperitoneal fibrosis below the pelvic rim is very rare. Clinical symptoms of pelvic fibrosis are variable and imaging findings may lead to a broad list of differential diagnoses. We present two patients with idiopathic pelvic fibrosis and discuss radiological findings and differential diagnoses of this rare disease. (orig.)

    Messalli, E M; Cobellis, L; Festa, B; Pecori, E; Stradella, L; Cobellis, G


    An interesting case of pelvic actinomycosis with paculiar clinical manifestation is presented. A 42 years-old patient came to our emergency service for an abdominal pelvic pain and fever. Past history showed IUD in situ for over 15 years. The patient was submitted to a ultrasonographic scan and a complete hematological screening was performed. The diagnosis was of subacute abdomen, and an exploratory laparotomy was carried out. During laparotomy an atypical reactive tissue and a suppurative cavity were found. The histological finding of tissue biopsy showed pelvic actinomycosis. On the basis of these findings the conclusion is drawn that a better prevention of pelvic actinomycosis is necessary of its diffusion in the last years due to sexual habit changes.

[Emory University Hospital, Musculoskeletal Division, Department of Radiology and Imaging Sciences, Atlanta, GA (United States); Labib, Sameh A. [Emory University Hospital, Department of Orthopaedic Surgery, Atlanta, GA (United States)


    The objectives of this work were to retrospectively describe the radiographic assessment of INBONE total ankle arthroplasty in 30 patients using validated linear and angular measurements and to correlate these findings with the final surgical outcome over a 2-year follow-up period. Thirty consecutive patients (21 females, nine males; mean age, 64.8 years) underwent INBONE total ankle arthroplasty during 2007-2011. After IRB approval, a retrospective pre- and post-operative radiographic analysis was performed using validated linear and angular measurements. The pre- and post-operative assessment included the tibial angle, talar angle, tibial slope, and coronal deformity. Post-operative measurements also included the talocalcaneal angle, joint space height, talar height, lateral tibial component angle, lateral talar component angle, and anteroposterior tibial component angle. The post-operative bone loss, subluxation, positioning, and subsidence were also assessed. Statistical analysis was performed using two-sample t test and Fisher's exact test. Out of 30 patients, 23 had a successful clinical outcome with intact prosthesis at a 2-year follow-up. The only variables with significant correlation (p < 0.05) to the post-surgical outcome were the lateral talar component angle (p = 0.002) and the mean difference between pre- and post-operative tibial slope (p = 0.001). The coronal deformity had significant mean difference between pre- and post-operative values (p < 0.001); however, it lacked a significant correlation to the final surgical outcome. None of the categorical variables had a significant correlation with post-surgical outcome. In our retrospective study, only the lateral talar component angle and the mean difference between the pre- and post-operative tibial slope had significant correlation with post-surgical outcome in INBONE ankle arthroplasty. These measurements may be helpful in radiographic assessment of the INBONE ankle arthroplasty. (orig.)

  10. Pelvic floor and sexual male dysfunction

    Directory of Open Access Journals (Sweden)

    Antonella Pischedda


    Full Text Available The pelvic floor is a complex multifunctional structure that corresponds to the genito- urinary-anal area and consists of muscle and connective tissue. It supports the urinary, fecal, sexual and reproductive functions and pelvic statics. The symptoms caused by pelvic floor dysfunction often affect the quality of life of those who are afflicted, worsening significantly more aspects of daily life. In fact, in addition to providing support to the pelvic organs, the deep floor muscles support urinary continence and intestinal emptying whereas the superficial floor muscles are involved in the mechanism of erection and ejaculation. So, conditions of muscle hypotonia or hypertonicity may affect the efficiency of the pelvic floor, altering both the functionality of the deep and superficial floor muscles. In this evolution of knowledge it is possible imagine how the rehabilitation techniques of pelvic floor muscles, if altered and able to support a voiding or evacuative or sexual dysfunction, may have a role in improving the health and the quality of life.

  11. Radiographic markers - A reservoir for bacteria?

    Energy Technology Data Exchange (ETDEWEB)

    Tugwell, Jenna, E-mail: [Department of Radiology, Ysbyty Gwynedd Hospital, Bangor, North Wales (United Kingdom); Maddison, Adele [Nuffield Health, Shrewsbury Hospital (United Kingdom)


    Introduction: Amongst the most frequently handled objects in the radiology department are radiographic markers. They are personal accessories used with every patient, and are kept in the radiographers pockets when not utilised. Upon enquiry it was discovered that many radiographers disregarded the potential of these accessories to become a vector for cross-contamination thus never or rarely clean them. The aims of this study were therefore to identify if radiographic markers are a reservoir for bacteria and to establish an effective cleaning method for decontaminating them. Methodology: 25 radiographers/student radiographers were selected for this study. Swabbing of their markers prior and post cleaning took place. The microbiology laboratory subsequently analyzed the results by quantifying and identifying the bacteria present. The participants also completed a closed questionnaire regarding their markers (e.g. frequency of cleaning and type of marker) to help specify the results gained from the swabbing procedure. Results: From the sample swabbed, 92% were contaminated with various organisms including Staphylococcus and Bacillus species, the amount of bacteria present ranged from 0 to >50 CFU. There were no significant differences between disinfectant wipes and alcohol gel in decontaminating the markers. Both successfully reduced their bacterial load, with 80% of the markers post cleaning having 0 CFU. Conclusion: The results indicated that radiographic markers can become highly contaminated with various organisms thus serve as a reservoir for bacteria. In addition, the markers need to be cleaned on a regular basis, with either disinfectant wipes or alcohol gel to reduce their bacterial load.

[Div. of Psychosocial Research and Epidemiology, Netherlands Cancer Inst., Amsterdam (Netherlands); Mosekilde, L. [Dept. of Cell Biology, Univ. of Aarhus (Denmark)


    Purpose: It has been hypothesized that photographs can facilitate the interpretation of the radiographic characteristics of trabecular bone. The reliability of these photographic and radiographic approaches has been determined, as have various agreements between the two approaches and their correlations with biomechanical characteristics. Material and Methods: Fourteen vertebral bodies were obtained at autopsy from 6 women and 8 men aged 22-76 years. Photographs (n=28) and radiographs (n=28) were taken of midsagittal slices from the third lumbar vertebra. The radiographs and photographs were digitized and the geometric properties of the trabecular architecture were then determined with a digital images analysis technique. Information on the compressive strength and ash density of the vertebral body was also available. Results: The geometric properties of both radiographs and photographs could be measured with a high degree of reliability (Cronbach`s {alpha}>0.85). Agreement between the radiographic and photographic approaches was mediocre as only the radiographic measurements showed insignificant correlations (p<0.05) with the biomechanical characteristics. We suggest that optical phenomena may result in the significant correlations between the photographs and the biomechanical characteristics. Conclusion: For digital image processing, radiography offers a superior description of the architecture of trabecular bone to that offered by photography. (orig.)

  13. Treatment of pelvic inflammatory disease. (United States)

    Cunha, B A


    The pathogenesis, risk factors, microbiology, sequelae, diagnosis, and treatment of pelvic inflammatory disease (PID) are reviewed, and factors associated with the selection of effective, safe, and economical drug therapy are discussed. PID is an acute clinical syndrome not related to surgery or pregnancy that is caused by the spread of microorganisms from the vagina and cervix to the endometrium, fallopian tubes, and other adnexal structures. Primary PID, the most common form of the disease, is the result of the ascent of sexually acquired or endogenous lower genital tract microorganisms to the upper genital tract. Presence of a sexually transmitted disease is the most common risk factor for PID, but a previous episode of PID, multiple sexual partners, intrauterine device use, and young age are also risk factors. PID is classified as gonococcal or nongonococcal (i.e., caused by anaerobic and aerobic pelvic organisms). The long-term consequences of PID are the most devastating aspects of the disease; infertility remains the most common sequela. Therapy of PID is aimed at preserving fertility, preventing long-term consequences, and relieving acute clinical symptoms. In areas in which penicillinase-producing Neisseria gonorrhoeae is endemic, therapy that is effective against penicillinase-producing N. gonorrhoeae is necessary. Gonococcal PID that is not penicillin resistant may be treated with a single intramuscular or oral dose of a penicillin; penicillin-resistant infection may be treated with a cephalosporin or ciprofloxacin. If chlamydia is a diagnostic consideration, a one- to two-week course of oral tetracycline or doxycycline (injectable-drug therapy is an alternative) should be added to the regimen. Single-agent therapy is a cost-effective alternative to combination regimens. Ampicillin-sulbactam is a cost-effective alternative to the more costly injectable cephalosporins or the combination regimens of an aminoglycoside plus clindamycin or metronidazole. With

    To determine the frequency of disease, and to evaluate the methods used for lumbar spine radiography in Korea. Sixty university and training hospitals were randomly selected and asked to describe the projections, film size and radiographic techniques employed for routine radiography in patients with suspected disease of the lumbar spine. Plain radiographs of 1215 patients, taken using 14x17 inch film and depicting both hip joints and the lumbar region, were analysed between March 1999 and February 2000. In 15 patients (1.2%), the radiographs revealed hip or pelvic lesion, confirmed as follows: avascular necrosis of the femoral head (n=11, with bilateral lesion in four cases); sustained ankylosing spondylitis (n=2); acetabular dysplasia (n=1); and insufficiency fracture of the pubic rami secondary to osteoporosis (n=1). In 11 or the 20 hospitals which responded, 14{sup x}17{sup f}ilm was being used for lumbar radiography, while in the other nine, film size was smaller. Plain radiography of the lumbar spine including both hip joints, may be a useful way to simultaneously evaluate lesions not only of the lumbar spine but also of the hip and/or pelvis.

  2. External fixation of the pelvic girdle as a test for assessing instability of the sacro-iliac joint. (United States)

    Slätis, P; Eskola, A


    External fixation of the pelvic girdle was used in a consecutive series of ten female patients suffering from suspected chronic instability of the sacro-iliac joint. The condition was attributed to pelvic relaxation after pregnancy in seven patients and to trauma in three. External fixation of the pelvis with a trapezoid frame reduced the average radiographic displacement of the symphysis from 5.0 to 2.4 mm in eight patients, relieved the dorsal pain in seven, and markedly improved walking ability in five. Seven of the ten patients were subsequently subjected to an anterior sacro-iliac joint arthrodesis in which square compression plates and autogenous bone grafts were used. At follow-up examination five of these patients were improved, and two unchanged. The results suggest that external fixation of the pelvis is useful in assessing painful sacro-iliac joint instability and should precede surgical intervention.

  3. Physical activity and the pelvic floor. (United States)

    Nygaard, Ingrid E; Shaw, Janet M


    Pelvic floor disorders are common, with 1 in 4 US women reporting moderate to severe symptoms of urinary incontinence, pelvic organ prolapse, or fecal incontinence. Given the high societal burden of these disorders, identifying potentially modifiable risk factors is crucial. Physical activity is one such potentially modifiable risk factor; the large number of girls and women participating in sport and strenuous training regimens increases the need to understand associated risks and benefits of these exposures. The aim of this review was to summarize studies reporting the association between physical activity and pelvic floor disorders. Most studies are cross-sectional and most include small numbers of participants. The primary findings of this review include that urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high-intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this examination finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for

    Chelli, Dalenda; Hassini, Abdelwahed; Aloui, Fadhel; Sfar, Ezzeddine; Zouaoui, Béchir; Chelli, Héla; Chanoufi, Badis


    Actinomycosis is a rare suppurative disease due to Actinomyces species. These Gram-positive, non-acid fast anaerobic filamentous bacteria are normal inhabitants of the human body, tending to reside in the oropharynx and bowel but are occasionally found in the vagina. Pelvic actinomycosis is a rare bacterial disease in women. Clinical manifestations are various and non specific and may be acute or chronic. No consensus exists for treatment. We reviewed files and identified all five cases of pelvic actinomycosis managed at Obstetrics and Gynaecology department "A" at the Maternity Center of Tunis over an eight-year period (1998-2005). The women's average age was 39.2 years. One patient was menopausal and consulted for bleeding. The other four patients were younger and had all been using an intrauterine device (IUD) for contraception. They presented with acute clinical manifestations. Their main symptom was pelvic pain. Three women had fever, and two presented with urinary tract obstruction. All patients had surgery. A pelvic abscess was found in four cases. Laparoscopic management was possible in only one case. Laparotomy was necessary in the other four. Four women had adnexectomies, two with hysterectomy. Digestive complications occurred in three cases. Actinomycosis was diagnosed only after surgery, by the histological examination. This series confirms the difficulties encountered in the management of pelvic actinomycosis. We review the recent literature and describe the diagnostic and therapeutic procedures currently recommended. The relationship between pelvic actinomycosis and IUDs, the most common method of contraception in Tunisia, is clearly established. Clinical diagnosis of pelvic actinomycosis is difficult because the symptoms are non-specific. Laboratory tests can help by showing serious inflammation, however. Imaging findings are also non-specific and may suggest an abscess or an inflammatory or neoplastic process. Interventional radiology, specifically

[Lucile Packard Children' s Hospital and Stanford University, Pediatric Radiology, Palo Alto, CA (United States); University of California, International Skeletal Dysplasia Registry, Los Angeles, CA (United States)


    Although mucolipidosis type II has similar metabolic abnormalities to those found in all the mucopolysaccharidoses and mucolipidoses, there are distinctive diagnostic radiographic changes of mucolipidosis II in the perinatal/newborn/infant period. To describe the early characteristic radiographic changes of mucolipidosis II and to document when these changes manifest and resolve. We retrospectively reviewed radiographs and clinical records of 19 cases of mucolipidosis II from the International Skeletal Dysplasia Registry (1971-present; fetal age to 21/2 years). A radiologist with special expertise in skeletal dysplasias evaluated the radiographs. The most common abnormalities were increased vertebral body height (80%, nonspecific), talocalcaneal stippling (86%), periosteal cloaking (74%) and vertebral body rounding (50%). Unreported findings included sacrococcygeal sclerosis (54%) and vertebral body sclerosis (13%). Rickets and hyperparathyroidism-like (pseudohyperparathyroidism) changes (rarely reported) were found in 33% of cases. These changes invariably started in the newborn period and resolved by 1 year of age. The conversion from these early infantile radiographic features to dysostosis multiplex changes occurred in 41% of cases, and within the first year after birth. Several findings strongly suggest the diagnosis of mucolipidosis II, including cloaking in combination with one or more of the following radiographic criteria: talocalcaneal stippling, sacrococcygeal or generalized vertebral body sclerosis, vertebral body rounding, or rickets/hyperparathyroidism-like changes in the perinatal/newborn/infancy period. These findings are not found in the other two forms of mucolipidosis nor in any of the mucopolysaccharidoses. (orig.)

  6. Radiographic signs and diagnosis of dental disease. (United States)

    Bellows, J


    Dental radiographs are critical for the complete assessment and treatment of dental diseases. Dental radiography is commonly used to evaluate congenital dental defects, periodontal disease, orthodontic manipulations, oral tumors, endodontic treatments, oral trauma, and any situation where an abnormality is suspected. Although standard radiographic equipment and film can be used to produce dental radiographs, dental X-ray equipment and film provide superior quality images and greater convenience of animal patient positioning. An understanding of normal dental radiographic anatomy is important when interpreting dental radiographs. Stage III periodontitis is the earliest stage of periodontal disease at which radiographic abnormalities become apparent. Bone loss associated with periodontal disease can be classified as either horizontal or vertical. Periapical radiolucencies can represent granulomas, cysts, or abscesses, whereas periapical radiodensities may represent sclerotic bone or condensing osteitis. Lytic lesions of the bone of the jaw often represent oral neoplasms. Neoplasms also can displace or disrupt teeth in the dental arch. Resorptive lesions can be external or internal and appear as radiolucent areas involving the external surface of the root or the pulp cavity, respectively. Feline dental resorptive lesions, also known as odontoclastic resorptions, are a specific form of dental resorptive lesions unique to cats.

  7. MRI of radiographically occult ischial apophyseal avulsions

[Cincinnati Children' s Hospital Medical Center, Department of Radiology, MLC 5031, Cincinnati, OH (United States)


    Acute avulsions of unossified ischial apophyses in children may go undetected on radiography. Therapy includes rest and rehabilitation; however, substantial displacement may require surgery. Our purpose is to illustrate the utility of MRI in the detection of these radiographically occult injuries in skeletally immature children. This retrospective study of more than 5 years included children with ischial avulsions who were evaluated with both radiography and MRI within 3 weeks of acute injury. Initially, radiographs were reviewed to identify those children with unossified ischial apophyses. Subsequently, their MRI examinations were assessed for physeal disruption, bone/soft tissue edema, periosteal/perichondrial elevation and disruption. Initial and follow-up radiographs (if available) were reviewed. Patient age, symptoms and offending activity were determined from clinical records. Five children met inclusion criteria. All initial radiographs were normal. MRI showed: edema (n = 5), periosteal elevation (n = 4), periosteal/perichondrial disruption (n = 4), >5.5 mm displacement (n = 0). Follow-up radiographs in two children (2 and 2.5 months from MRI) showed osseous ischial irregularity. The apophyses remained unossified. Acute unossified ischial apophyseal avulsions in children may be radiographically undetected. In the setting of correlative clinical symptoms, MRI can be used to identify these injuries and to help direct appropriate therapy. (orig.)

  8. The Surgical Treatment of Pelvic Bone Metastases

    Directory of Open Access Journals (Sweden)

    Daniel A. Müller


    Full Text Available Pelvic bone metastases are a growing concern in the field of orthopedic surgery. Patients with pelvic metastasis are individually different with different needs of treatment in order to attain the best possible quality of life despite the advanced stage of disease. A holistic collaboration among the oncologist, radiation therapist, and orthopedic surgeon is mandatory. Special attention has to be directed to osteolytic lesions in the periacetabular region as they can provoke pathological fractures and subsequent functional impairment. Different reconstruction techniques for the pelvis are available; the choice depends on the patient’s prognosis, size of the bone defect, and response of the tumor to adjuvant treatment. If all the conservative treatments are exhausted and the patient is not eligible for surgery, one of the various percutaneous ablation procedures can be considered. We propose a pelvic analogue to the treatment algorithm in long bone metastasis and a scoring system in pelvic metastasis. This algorithm aims to simplify the teamwork and to avoid under- or overtreatment of pelvic bone metastases.

  9. Possible retrogenesis observed with fiber tracking: an anteroposterior pattern of white matter disintegrity in normal aging and Alzheimer's disease. (United States)

    Gao, Junling; Cheung, Raymond Tak-Fai; Lee, Tatia M C; Chu, Leung-Wing; Chan, Ying-Shing; Mak, Henry Ka-Fung; Zhang, John X; Qiu, Deqiang; Fung, Germaine; Cheung, Charlton


    Retrogenesis refers to the phenomenon by which degenerative processes in aging reverse the sequence of acquisition in development. Although there has been some evidence for brain retrogenesis in abnormal aging, e.g., Alzheimer's disease (AD), it has not been explicitly addressed in the normal aging. Using diffusion tensor imaging and tractography, we explored the effects of normal and abnormal aging on the integrity of white matter (WM) in fifty participants, including 18 AD patients, 17 normal elderly, and 15 normal young adults. Compared with young adults, the traditional voxel-based analysis, and the quantitative fiber tracking methods revealed lower fractional anisotrophy (FA) for both normal elderly and AD patients, indicating WM disintegrity in the anterior part of the brain with developmentally late-myelinating fiber bundles. Furthermore, AD patients showed lower FA in the posterior part of the brain with relatively early-myelinating fiber bundles. Additional analysis on axial diffusion and radial diffusion measures suggest that demyelination may be the main mechanism underlying the observed microstructural impairments. Consistent with a proposal of retrogenesis, our results demonstrate an anteroposterior pattern of white matter disintegrity in both normal aging and AD, with the pattern being more salient in the latter than in the former.

  10. R-spondin 3 regulates dorsoventral and anteroposterior patterning by antagonizing Wnt/β-catenin signaling in zebrafish embryos.

    Directory of Open Access Journals (Sweden)

    Xiaozhi Rong

    Full Text Available The Wnt/β-catenin or canonical Wnt signaling pathway plays fundamental roles in early development and in maintaining adult tissue homeostasis. R-spondin 3 (Rspo3 is a secreted protein that has been implicated in activating the Wnt/β-catenin signaling in amphibians and mammals. Here we report that zebrafish Rspo3 plays a negative role in regulating the zygotic Wnt/β-catenin signaling. Zebrafish Rspo3 has a unique domain structure. It contains a third furin-like (FU3 domain. This FU3 is present in other four ray-finned fish species studied but not in elephant shark. In zebrafish, rspo3 mRNA is maternally deposited and has a ubiquitous expression in early embryonic stages. After 12 hpf, its expression becomes tissue-specific. Forced expression of rspo3 promotes dorsoanterior patterning and increases the expression of dorsal and anterior marker genes. Knockdown of rspo3 increases ventral-posterior development and stimulates ventral and posterior marker genes expression. Forced expression of rspo3 abolishes exogenous Wnt3a action and reduces the endogenous Wnt signaling activity. Knockdown of rspo3 results in increased Wnt/β-catenin signaling activity. Further analyses indicate that Rspo3 does not promote maternal Wnt signaling. Human RSPO3 has similar action when tested in zebrafish embryos. These results suggest that Rspo3 regulates dorsoventral and anteroposterior patterning by negatively regulating the zygotic Wnt/β-catenin signaling in zebrafish embryos.

    Stoker, Jaap [Department of Radiology, Academic Medical Center, University of Amsterdam (Netherlands); Bartram, Clive I.; Halligan, Steve [Intestinal Imaging Centre, St. Mark' s Hospital, London (United Kingdom)


    Disorders of the posterior pelvic floor are relatively common. The role of imaging in this field is increasing, especially in constipation, prolapse and anal incontinence, and currently imaging is an integral part of the investigation of these pelvic floor disorders. Evacuation proctography provides both structural and functional information for rectal voiding and prolapse. Dynamic MRI may be a valuable alternative as the pelvic floor muscles are visualised, and it is currently under evaluation. Endoluminal imaging is important in the management of anal incontinence. Both endosonography and endoanal MRI can be used for detection of anal sphincter defects. Endoanal MRI has the advantage of simultaneously evaluating external sphincter atrophy, which is an important predictive factor for the outcome of sphincter repair. Many aspects of constipation and prolapse remain incompletely understood and treatment is partly empirical; however, imaging has a central role in management to place patients into treatment-defined groups.

    With the Chinese development of industry, agriculture and communication, various traffic and work related accidents are increasing, leading to an increase in pelvic fractures. Among the different kinds of fractures, pelvic fracture is the third largest cause of death.1 The treatment of pelvic fractures is a “hot spot” and a difficult point in orthopedic surgery. Since 1998 we have treated 20 patients with vertical unstable pelvic fracture using anterior internal fixation. Satisfactory results have been obtained.

  18. Should axial spondyloarthritis without radiographic changes be treated with anti-TNF agents? (United States)

    Keat, Andrew; Bennett, Alexander N; Gaffney, Karl; Marzo-Ortega, Helena; Sengupta, Raj; Everiss, Tamara


    A spectrum of disease extends beyond the rigid confines of ankylosing spondylitis (AS). Axial spondyloarthritis (axSpA) encompasses non-radiographic axSpA (nr-axSpA) in individuals without established radiographic changes but with other clinical/imaging axSpA features and AS in those with definite sacroiliac joint changes on pelvic X-rays. A broad consensus about the management of nr-axSpA is emerging among clinicians, but the evidence base remains open to question. To explore whether nr-axSpA and AS should be treated similarly, we examined the literature on their prevalence, natural history, disease burden, and treatment. There is strong evidence that nr-axSpA and AS are expressions of the same disease. Approximately 10% of patients with nr-axSpA will develop radiographic disease over 2 years; after >20 years, the figure may exceed 80%. Nr-axSpA patients have lower CRP and less spinal inflammation on MRI than AS patients but similar disease activity, pain, and quality-of-life impairment. Most patients with nr-axSpA manage well with conservative treatment, but a minority has severe disabling symptoms. Anti-TNF therapy has demonstrated similar efficacy and safety in nr-axSpA and AS. Current evidence does not clearly indicate that anti-TNF treatment can inhibit or limit bony progression of AS, the basis of conservative and anti-TNF treatment is control of symptoms and function. For some patients with nr-axSpA, the need for powerful treatments is as great as in some with AS; thus, treatment of axSpA should be consistent across the axSpA spectrum with anti-TNF agents being available, irrespective of radiographic change, according to the same criteria as those applied to AS.

  19. Functional imaging of the pelvic floor

    Energy Technology Data Exchange (ETDEWEB)

    Lienemann, Andreas E-mail:; Fischer, Tanja


    Introduction/Objective: Pelvic floor dysfunction and associated pelvic organ prolapse represent a major problem in our present-day society, mostly afflicting parous women. Magnetic resonance imaging (MRI) is assuming an increasingly important role in the more accurate delineation of the extent of the problem. This article briefly reviews one of the main radiological methods for the dynamic evaluation of the pelvic floor: functional cine MRI. Methods and Material: Out of the literature the smallest common denominator for functional cine MRI can be defined as follows: high field system; patient either in supine or sitting position; fast gradient echo sequence; midsagittal slice orientation; either a stack of slices or repeated measurements at the same slice position with the patient at rest or straining; image analysis using the pubococcygeal reference line. Results: All except two publications stress the usefulness of functional cine MRI in the evaluation of patients with organ descent and prolapse. This well accepted method allows for the visualization of all relevant structures in the anterior, middle and posterior compartment. It is especially useful in the detection of enteroceles, and provides a reliable postoperative follow-up tool. Isolated urinary or stool incontinence are not an indication for functional cine MRI, as is the case in patients with equivocal clinical findings. To date it does not allow for real 3D imaging of the pelvic floor or sufficient determination of fascial defects. Discussion: Functional cine MRI of the pelvic floor is a promising new imaging method for the detection of organ descent and prolapse in patients with equivocal clinical findings. The combination of function and morphology allows for an innovative view of the pelvic floor, and thus adds to our understanding of the various interactions of the structures.

  20. Laparoendoscopic single site in pelvic surgery. (United States)

    Sanchez-Salas, Rafael; Clavijo, Rafael; Barret, Eric; Sotelo, Rene


    Laparoendoscopic single site (LESS) has recently gained momentum as feasible techniques for minimal access surgery. Our aim is to describe the current status of laparoendoscopic single site (LESS) in pelvic surgery. A comprehensive revision of the literature in LESS pelvic surgery was performed. References for this manuscript were obtained by performing a review of the available literature in PubMed from 01-01-01 to 30-11-11. References outside the search period were obtained selected manuscript΄s bibliography. Search terms included: pelvic anatomy, less in gynecology, single port colectomy, urological less, single port, single site, NOTES, LESS and single incision. 314 manuscripts were initially identified. Out of these, 46 manuscripts were selected based in their pelvic anatomy or surgical content; including experimental experience, clinical series and literature reviews. LESS drastically limit the surgeon's ability to perform in the operative field and the latter becomes hardened by the lack of space in anatomical location like the pelvis. Potential advantages of LESS are gained with the understanding that the surgical procedure is more technically challenging. Pelvic surgical procedures related to colorectal surgery, gynecology and urology have been performed with LESS technique and information available is mostly represented by case reports and short case series. Comparative series remain few. LESS pelvic surgery remain in its very beginning and due to the very specific anatomical conditions further development of LESS surgery in the mentioned area can be clearly be facilitated by using robotic technology. Standardization ad reproducibility of techniques are mandatory to further develop LESS in the surgical arena..

  5. Role of female pelvic anatomy in infertility. (United States)

    Harris-Glocker, Miranda; McLaren, Janet F


    Infertility is defined as a couple's failure to achieve pregnancy after one year of regular, unprotected intercourse. The etiology of infertility can be due to female factors, male factors, combined male and female factors, or have an unknown etiology. This review focuses on the role of female pelvic anatomy in infertility. Normal anatomy and the physiology of reproduction will be discussed, as well as the anatomic and pathophysiologic processes that cause infertility including ovulatory disorders, endometriosis, pelvic adhesions, tubal blockage, mullerian anomalies, and abnormalities affecting the uterine cavity such as leiomyomata and endometrial polyps.

  6. Total Pelvic Exenteration for Gynecologic Malignancies

    Directory of Open Access Journals (Sweden)

    Elisabeth J. Diver


    Full Text Available Total pelvic exenteration (PE is a radical operation, involving en bloc resection of pelvic organs, including reproductive structures, bladder, and rectosigmoid. In gynecologic oncology, it is most commonly indicated for the treatment of advanced primary or locally recurrent cancer. Careful patient selection and counseling are of paramount importance when considering someone for PE. Part of the evaluation process includes comprehensive assessment to exclude unresectable or metastatic disease. PE can be curative for carefully selected patients with gynecologic cancers. Major complications can be seen in as many as 50% of patients undergoing PE, underscoring the need to carefully discuss risks and benefits of this procedure with patients considering exenterative surgery.

  7. Diagnosis and therapy of pelvic actinomycosis. (United States)

    Taga, Shigeki


    Pelvic actinomycosis is difficult to diagnose. In most cases, it is not diagnosed until after surgery. If this condition is diagnosed preoperatively, it can be treated in many cases. Three cases of actinomycosis are reported here. Three women with intrauterine devices (IUD) each presented with lower abdominal pain and pelvic mass, and elevated white blood cell count and C-reactive protein. Left salpingo-oophorectomy was performed for one the women. The pathological diagnosis was actinomycosis. For the other two women, a Gram or Papanicolaou stain of the IUD sample showed actinomycetes. They were discharged after intravenous administration of penicillin without surgery.

  9. Radiographic Parameters in Adult Degenerative Scoliosis and Different Parameters Between Sagittal Balanced and Imbalanced ADS Patients. (United States)

    Yang, Changwei; Yang, Mingyuan; Chen, Yuanyuan; Wei, Xianzhao; Ni, Haijian; Chen, Ziqiang; Li, Jingfeng; Bai, Yushu; Zhu, Xiaodong; Li, Ming


    A retrospective study. To summarize and describe the radiographic parameters of adult degenerative scoliosis (ADS) and explore the radiological parameters which are significantly different in sagittal balanced and imbalanced ADS patients. ADS is the most common type of adult spinal deformity. However, no comprehensive description of radiographic parameters in ADS patients has been made, and few studies have been performed to explore which radiological parameters are significantly different between sagittal balanced and imbalanced ADS patients. Medical records of ADS patients in our outpatient clinic from January 2012 to January 2014 were reviewed. Demographic data including age and sex, and radiographic data including the coronal Cobb angle, location of apical vertebra/disc, convexity of the curve, degree of apical vertebra rotation, curve segments, thoracic kyphosis (TK), lumbar lordosis (LL), thoracolumbar kyphosis (TL), sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), sagittal vertical axis (SVA), and PI minus LL (PI-LL) were reviewed to make comprehensive description of radiographic parameters of ADS. Furthermore, patients were divided into 2 groups according to whether the patients' sagittal plane was balanced: Group A (imbalanced, SVA > 5 cm) and Group B (balanced, SVA  ≤ 5 cm). Demographic and radiological parameters were compared between these 2 groups. A total of 99 patients were included in this study (Group A = 33 and Group B = 66; female = 83 and male = 16; sex ratio = 5:1). The median of age were 67 years (range: 41-92 years). The median of coronal Cobb angle and length of curve was 23 (range: 10-75°) and 5 segments (range: 3-7), respectively. The most common location of apical vertebra was at L2 to L3 (81%) and the median of degree of apical vertebra rotation was 2° (range: 1-3). Our study also showed significant correlations between coronal Cobb angle and curve segments (r = 0.23, P sagittal balance, there were significant

    Yoo, Dong Soo [Dept. of Radiology, College of Dentistry, Seoul National University , Seoul (Korea, Republic of)


    The author analysed the routine radiographic changes and clinical symptoms of 205 cases of temporomandibular joint arthrosis. The clinical symptoms of the patients were classified and the morphological changes of condylar head, articular eminence, and articular fossa were analyzed and discussed from radiographic view point. The positional change of condylar head and articular fossa relation in TMJ arthrosis were observed. The frequencies of coincidence between the site of complaints and the site of the abnormal images which could be detected were examined. The results were obtained as follows; 1. Bone erosion, deformity, marginal proliferation and sclerosis were selected from many abnormal images as the radiographic diagnostic criteria of TMJ arthritic lesions. 2. Abnormal radiographic findings were revealed in 150 cases (73.9%) of 205 total TMJ arthrosis cases and site with abnormal findings coincided with the site of complaints in 105 cases (70.7%) of 150 cases and coincidence rates were higher above fourth decades than below third decades. 3. Sclerosis of the abnormal radiographic findings could be found more often below third decades than above fourth decades. 4. The positional changes of condylar head were revealed in 176 cases (85.9%) of 205 total cases. 5. Pain complaints were revealed in 170 cases(82.9%) and clicking sounds were revealed in 120 cases (58.6%) of clinical symptoms of TMJ arthrosis. 6. No tendency was found so far the differential diagnosis between pain dysfunction syndrome and osteoarthrosis of TMJ.

    We present the case of a former user of an intrauterine contraceptive device (IUD) for 10 years, diagnosed with a bulky, fixed pelvic tumor involving the internal genital organs and the recto sigmoid, causing luminal narrowing of the rectum, interpreted as locally advanced pelvic malignancy, probably of genital origin. Intraoperatively, a high index of suspicion made us collect a sample from the fibrous wall of the tumor mass, large Actinomyces colonies were thus identified. Surgery consisted in debridement, removal of a small amount of pus and appendectomy, thus avoiding a mutilating and useless surgery. Specific antibiotic therapy was administered for 3 months, with favorable postoperative and long-term outcomes. Pelvic actinomycosis should always be considered in the differential diagnosis of pelvic tumors in women using an IUD. The association of long-term antibiotic treatment is essential to eradicate the infection and prevent relapses.

  13. Sox31 is involved in central nervous system anteroposterior regionalization through regulating the organizer activity in zebrafish

    Institute of Scientific and Technical Information of China (English)

    Shengnan Hu; Zhili Wu; Yuanchang Yan; Yiping Li


    Sox superfamily proteins are DNA-binding transcriptional factors that contain highly conserved high-mobility group (HMG) box and take part in various development process.Sox31 is a maternal factor supplied in the oocyte and starts its zygotic expression during mid-blastula transition (MBT)From gastrulation stage, it mainly resides in neural tissue.Ectopically expression of Sox31 mRNA leads to cyclopia fusion eyes or totally loss of anterior head structure, in accompany with severe notochord defects. Molecular markers indicate that forebrain tissue reduces sharply while the posterior neural tissue expands anteriorly. In addition organizer specification is also suppressed. Oppositely, an antisense morpholino designed functionally knockdown Sox31 causes typically dorsalized phenotype and reversed central nervous system (CNS) anteroposterior (AP) patterning. Gain of function with chimeric construct, where Sox31 HMG DNA binding domain is fused to a transcription activation domain (VP16) or transcnption suppression domain (EnR), suggests that Sox31 acts as a transcriptional suppressor in vivo. The expression of Bozozok (Dharma), a direct target gene of pre-MBT Wnt/p-catenin signal is suppressed by Sox31 Thus, to unveil the relationship between Sox31 and β-catenin-related transcriptional activity, we designed Top/Fop luciferase assay in HEK293T cells, and found that Sox31 could indeed suppress Tcf/Lef-dependent transcriptional activity without influencing the stability of β-catenin.Moreover, post-MBT Wnt signal was reduced in Sox31 morphants corresponding to the suppressed hindbrain structure, while phenotypic defects caused by excessive Sox31 could be rescued by Wnt antagonist dkkl. Taken together, Sox31 functions as an essential CNS AP patterning determinant and coordinates the CNS AP patterning process with organizer specification.

  14. Stereospecificity and PAX6 function direct Hoxd4 neural enhancer activity along the antero-posterior axis. (United States)

    Nolte, Christof; Rastegar, Mojgan; Amores, Angel; Bouchard, Maxime; Grote, David; Maas, Richard; Kovacs, Erzsebet Nagy; Postlethwait, John; Rambaldi, Isabel; Rowan, Sheldon; Yan, Yi-Lin; Zhang, Feng; Featherstone, Mark


    The antero-posterior (AP) and dorso-ventral (DV) patterning of the neural tube is controlled in part by HOX and PAX transcription factors, respectively. We have reported on a neural enhancer of Hoxd4 that directs expression in the CNS with the correct anterior border in the hindbrain. Comparison to the orthologous enhancer of zebrafish revealed seven conserved footprints including an obligatory retinoic acid response element (RARE), and adjacent sites D, E and F. Whereas enhancer function in the embryonic CNS is destroyed by separation of the RARE from sites D-E-F by a half turn of DNA, it is rescued by one full turn, suggesting stereospecific constraints between DNA-bound retinoid receptors and the factor(s) recognizing sites D-E-F. Alterations in the DV trajectory of the Hoxd4 anterior expression border following mutation of site D or E implicated transcriptional regulators active across the DV axis. We show that PAX6 specifically binds sites D and E in vitro, and use chromatin immunoprecipitation to demonstrate recruitment of PAX6 to the Hoxd4 neural enhancer in mouse embryos. Hoxd4 expression throughout the CNS is reduced in Pax6 mutant Sey(Neu) animals on embryonic day 8. Additionally, stage-matched zebrafish embryos having decreased pax6a and/or pax6b activity display malformed rhombomere boundaries and an anteriorized hoxd4a expression border. These results reveal an evolutionarily conserved role for Pax6 in AP-restricted expression of vertebrate Hoxd4 orthologs.

  15. Complete pelvic floor repair in treating fecal incontinence. (United States)

    Lee, Patrick Y H; Steele, Scott R


    Fecal incontinence is associated with 20 to 40% of the patients with pelvic floor prolapse. Successful management of fecal incontinence requires not only an understanding of anorectal function but also a thorough understanding of pelvic floor anatomy and how pelvic floor prolapse affects fecal continence. Imaging techniques have been instrumental in visualizing pelvic floor prolapse and have helped correlate surgical findings. Stabilization of the perineal body appears to be a key component to the success of pelvic floor repair and fecal continence, but the optimal repair is far from being established.

  17. Giant colonic diverticulum: radiographic and MDCT characteristics. (United States)

    Zeina, Abdel-Rauf; Mahamid, Ahmad; Nachtigal, Alicia; Ashkenazi, Itamar; Shapira-Rootman, Mika


    Giant colonic diverticulum (GCD), defined as a diverticulum larger than 4 cm, is a rare entity that is generally a manifestation of colonic diverticular disease. Because of its rarity and its variable and non-specific presentation, the diagnosis of GCD depends mainly on imaging findings. Knowledge of the spectrum of radiographic and CT features of the GCD is important in making the correct diagnosis and potentially preventing complications. This review focuses on imaging findings characteristic of GCD as well as its complications and radiographic mimics. Teaching points • Giant colonic diverticulum is a rare complication of diverticulosis.• The most common symptom is abdominal pain presenting in approximately 70 % of patients.• Diagnosis is based on imaging findings with plain abdominal radiographs and MDCT.• Treatment consists of en bloc resection of the diverticulum and affected adjacent colon.

  1. Sexual selection targets cetacean pelvic bones. (United States)

    Dines, James P; Otárola-Castillo, Erik; Ralph, Peter; Alas, Jesse; Daley, Timothy; Smith, Andrew D; Dean, Matthew D


    Male genitalia evolve rapidly, probably as a result of sexual selection. Whether this pattern extends to the internal infrastructure that influences genital movements remains unknown. Cetaceans (whales and dolphins) offer a unique opportunity to test this hypothesis: since evolving from land-dwelling ancestors, they lost external hind limbs and evolved a highly reduced pelvis that seems to serve no other function except to anchor muscles that maneuver the penis. Here, we create a novel morphometric pipeline to analyze the size and shape evolution of pelvic bones from 130 individuals (29 species) in the context of inferred mating system. We present two main findings: (1) males from species with relatively intense sexual selection (inferred by relative testes size) tend to evolve larger penises and pelvic bones compared to their body length, and (2) pelvic bone shape has diverged more in species pairs that have diverged in inferred mating system. Neither pattern was observed in the anterior-most pair of vertebral ribs, which served as a negative control. This study provides evidence that sexual selection can affect internal anatomy that controls male genitalia. These important functions may explain why cetacean pelvic bones have not been lost through evolutionary time.

    ABSTRACT Objectives To evaluate the feasibility, safety and surgical results of skeletonized mesh implants to form a pelvic harness for pelvic floor reconstruction surgery. Study design Patients with advanced pelvic floor prolapse were enrolled to this study. Study model was a kit mesh, reduced to 75% of the original surface area by cutting out mesh material from the central mesh body. Patients were evaluated at the end of the 1st and 6th post-operative months and interviewed at the study conclusion. Results Ninety-five women with advanced pelvic floor prolapse had this implant. Mean follow-up duration was 9 months (6-12 months). The POP-Q point’s measurements showed marked and statistically significant improvements. Bladder over-activity symptoms, fecal incontinence, pelvic pain and constipation rates were all reduced as well. No adverse effects related to the dissection or mesh implantation were marked. The first and sixth post-operative month follow-up records as well as the study conclusion interview findings were satisfactory in terms of subjective and objective cure and adverse effects occurrence. Conclusion This study data proposes that skeletonizing meshes might be safely and successfully implanted for potentially improved pelvic floor reconstruction. PMID:27286114

  4. Pelvic floor dysfunction in inflammatory bowel disease. (United States)

    Bondurri, A; Maffioli, A; Danelli, P


    Advances in tailored medical therapy and introduction of biologic agents for inflammatory bowel disease (IBD) treatment have ensured long-term disease remission. Some patients, however, still report defecatory symptoms. Patients present with a wide spectrum of conditions - anal incontinence, obstructed defecation and pelvic pain among the most frequent - that have a great impact on their quality of life. Due to IBD diagnosis, little relevance is attributed to this type of symptoms and their epidemiologic distribution is unknown. Pathogenetic hypotheses are currently under investigation. Routine diagnostic workflow and therapeutic options in pelvic floor service are often underused. The evaluation of these disorders starts with an endoscopy to rule out ongoing disease; the following diagnostic workflow is the same as in patients without IBD. For fecal incontinence and obstructed defecation, simple conservative therapy with dietary modifications and appropriate fluid intake is effective in most cases. In non-responding patients, anorectal physiology tests and imaging are required to select patients for pelvic floor muscle training and biofeedback. These treatments have been proven effective in IBD patients. Some new minimally invasive alternative strategies are available for IBD patients, as sacral nerve and posterior tibial nerve stimulation; for other ones (e.g., bulking agent implantation) IBD still remains an exclusion criterion. In order to preserve anatomical areas that could be useful for future reconstructive techniques, surgical options to cure pelvic floor dysfunction are indicated only in a small group of IBD patients, due to the high risk of failure in wound healing and to the possible side effects of surgery, which can lead to anal incontinence or to a possible proctectomy. A particular issue among defecatory symptoms in patients with IBD is paradoxical puborectalis contraction after restorative proctocolectomy: if this disorder is properly diagnosed, a

    Abdel-Moniem Barakat, Ahmed; Abou-ElFetouh, Adel; Hakam, Maha Mohammed; El-Hawary, Hesham; Abdel-Ghany, Khaled Mahmoud


    The bilateral sagittal split osteotomy (BSSO) is one of the main orthognathic surgery procedures used for managing skeletal mandibular excess, deficiency or asymmetry. It is known to be a technique-sensitive procedure with high reported incidences of inferior alveolar nerve injury, bad splits and post-surgical relapse. With the increasing use of computer-assisted techniques in orthognathic surgery, the accurate transfer of the virtual plan to the operating room is currently a subject of research. This study evaluated the efficacy of computer-generated device at maintaining the planned condylar position and minimizing inferior alveolar nerve injury during BSSO. The device was used in 6 patients who required isolated mandibular surgery for correction of their skeletal deformities. Clinical evaluation showed good recovery of the maximal incisal opening and a reproducible occlusion in 5 of the 6 patients. Radiographic evaluation showed better control of the condyle position in both the vertical and anteroposterior directions than in the mediolateral direction. The degree of accuracy between the planned and achieved screw positions were judged as good to excellent in all cases. Within the limitations of this study and the small sample size, the proposed device design allowed for good transfer of the virtual surgical plan to the operating room.

    The purpose of this study was to evaluate the detectability of various radiographic techniques for mandibular condylar lesions. Erosive lesion, osteophyte and flattening were formed on the artificial mandibular condyle, and panoramic, transcranial, transorbital radiography, lateral and frontal tomography were taken. The results were as follows; 1. The detectability for erosive lesions was superior in the order of frontal tomography (96%), lateral tomography (78%), transorbital (59%), transcranial (56%) and panoramic (48%) radiography. 2. The location of erosive lesion that showed the highest detectability was the medial third in panoramic, the lateral third in transcranial, the central portion of anteroposterior direction in transorbital, the central portion of mediolateral direction and the posterior third in lateral tomography. Frontal tomography disclosed all erosive lesions except one anterolateral lesion. 3. The detectability of osteophyte was 100% in lateral tomography, 78% in transcranial and 56% in panoramic radiography. 4. For flattening, lateral tomography showed the flattened condyle, but both panoramic and transcranial views showed only decreased bone density without the change of condylar shape.

    The presence of a persistent left-sided superior vena cava (LSVC) in the absence of a right-sided superior vena cava (RSVC) may be suspected on a posteroanterior (PA) chest radiograph because of a prominent-appearing ascending aorta, which results from the absence of the RSVC. In the absence of an RSVC, the right upper lobe abuts and outlines the course of the ascending aorta, allowing better demonstration of its profile. This report describes a patient with this finding on a PA chest radiograph. Computed tomographic correlation is presented.

    We report the skull radiograph, CT and MRI findings in three patients with lymphocytic adenohypophysitis mimicking pituitary adenoma. All cases were associated with pregnancy. CT demonstrated a pituitary mass but did not differentiate lymphocytic adenohypophysitis from pituitary adenoma. The skull radiographs showed either a normal sella turcica or minimal abnormalities; they did not show ballooning or destruction. The MRI appearances were distinctive: relatively low signal on T1-weighted images; preservation of the bright posterior pituitary lobe despite the presence of a relatively large pituitary mass, less common in macroadenomas; marked contrast enhancement compared with pituitary macroadenomas; and dural enhancement adjacent to a pituitary mass.

Progestogen was more effective than combined oral contraceptive pills in controlling dysmenorrhea (RR:-0.160; CI:-0.386-0.066, however, progestogen is associated with more side effects like spotting and bloating than the combined contraceptive pills. Conclusion: Combined oral contraceptive pills (COCP, GnRHa and progestogens are equally effective in relieving endometriosis associated pelvic pain. COCP and progestogens are relatively cheap and more suitable for long-term use as compared to GnRHa. Long-term RCT of medicated contraceptive devices like Mirena and Implanon are required to evaluate their long-term effects on relieving the endometriosis associated pelvic pain

    Sudhir, G; Acharya, Shankar; K L, Kalra; Chahal, Rupinder


    Study Design Cross-sectional study. Objective Sacropelvic parameters in various spine and hip disorders have been published in various studies. We aimed to study the normal sacropelvic parameters and curvatures of the spine and their correlation in asymptomatic Indian adults in relation to variations in sex and age. Methods The study included 101 asymptomatic adults (50 men and 51 women with an average age of 47.16 and 48.59 years, respectively). For each subject, the thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS) were measured from standing lateral radiographs. After stratification of the group by sex and age with a cutoff of 50 years, descriptive, correlation, and regression analysis were performed using SPSS software. Results The average PI, SS, PT, LL, and TK values were 55.48 (±5.31), 35.99 (±7.53), 17.97 (±7.16), 48.84 (±9.82), and 32.55 (±10.92), respectively. No statistically significant difference was observed in these values with regards to sex and age  50 years but the pelvic incidence was found to be higher in women. A positive correlation between the PI and SS and a negative correlation between the SS and PT was observed. A positive correlation between the TK and LL was found in subjects > 50 years. Simple and multiple regression analyses were also performed for different groups. Conclusion The current study is the first of asymptomatic Indian adults and provides invaluable information to the clinicians about the normal range of sacropelvic and spinopelvic parameters, which is useful to plan spinal deformity corrections and to evaluate pathologic conditions associated with abnormal angular values.

    Mumby, C; Bouts, T; Sambrook, L; Danika, S; Rees, E; Parry, A; Rendle, M; Masters, N; Weller, R


    Foot problems are extremely common in elephants and radiography is the only imaging method available but the radiographic anatomy has not been described in detail. The aims of this study were to develop a radiographic protocol for elephant feet using digital radiography, and to describe the normal radiographic anatomy of the Asian elephant front and hind foot. A total of fifteen cadaver foot specimens from captive Asian elephants were radiographed using a range of projections and exposures to determine the best radiographic technique. This was subsequently tested in live elephants in a free-contact setting. The normal radiographic anatomy of the Asian elephant front and hind foot was described with the use of three-dimensional models based on CT reconstructions. The projection angles that were found to be most useful were 65-70° for the front limb and 55-60° in the hind limb. The beam was centred 10-15 cm proximal to the cuticle in the front and 10-15 cm dorsal to the plantar edge of the sole in the hind foot depending on the size of the foot. The protocol developed can be used for larger-scale diagnostic investigations of captive elephant foot disorders, while the normal radiographic anatomy described can improve the diagnostic reliability of elephant feet radiography.

  15. Identifying murder victims with endodontic radiographs (United States)

    Silva, Rhonan Ferreira; Franco, Ademir; Mendes, Solon Diego Santos Carvalho; Picoli, Fernando Fortes; Nunes, Fernando Gomes; Estrela, Carlos


    Endodontics is a special branch of dentistry constantly guided by imaging examinations. From a forensic scope, endodontics plays a valuable role providing solid antemortem (AM) radiographic evidence for comparison with postmortem findings in human identifications. This study illustrates the interface between endodontics and forensic odontology describing three cases of human identification based on radiographic endodontic records. From 2009 to 2012, three unknown male victims of murder were examined in a local Brazilian medico-legal institute to retrieve identity and potential cause of death. Specifically, when asked for AM data, a relative of the three victims provided periapical radiographs of endodontic treatments. Based on that, forensic dentists reproduced the same imaging acquisition techniques obtaining similar periapical radiographs, enabling a comparative dental identification. All the victims were positively identified based on patterns of dental morphology and treatment intervention. This study draws the attention of general and forensic dentists highlight the importance of properly recording dental treatments and searching for evidence in AM endodontic data, respectively.

    Full Text Available Context: Changes in the size of dental pulp caused by the apposition of secondary dentin and occlusal wear are morphometric parameters for estimating age. Aim: To estimate the accuracy of age evaluation by Kvaal's method and the effect of occlusal wear on age using digital intraoral periapical radiographs in a subset of the Indian population. Materials and Methods: A total of 300 teeth were radiographically evaluated using intraoral periapical digital radiographs from 50 adult patients. A few modifications were made in the design of the study compared to the original Kvaal's method. The radiographs of three teeth from each jaw were taken and morphometric measurements in ratios were analyzed, which included the pulp length to tooth length (X1, pulp length to root length (X2, pulp width to root widths at three defined levels (X3, and tooth length to root length (X4. Statistical Analysis: The Pearson product-moment correlation coefficient (PCC between age and the morphological variables showed that among them X1, X2, and X3were statistically significant but not the tooth root length ratio (X4. Conclusions: The ratios X1, X2, and X3were good indicators of age and hence a multiple linear regression model for age estimation was derived using these three variables. However, it was found that X4was not a good indicator of age estimation in said population.

    Perek Asiye


    Full Text Available Abstract Introduction Pelvic actinomycosis constitutes 3% of all human actinomycosis infections. It is usually insidious, and is often mistaken for other conditions such as diverticulitis, abscesses, inflammatory bowel disease and malignant tumors, presenting a diagnostic challenge pre-operatively; it is identified post-operatively in most cases. Here we present a case that presented as pelvic malignancy and was diagnosed as pelvic actinomycosis post-operatively. Case presentation A 48-year-old Caucasian Turkish woman presented to our clinic with a three-month history of abdominal pain, weight loss and difficulty in defecation. She had used an intra-uterine device for 16 years, however it had recently been removed. The rectosigmoidoscopy revealed narrowing of the lumen at 12 cm due to a mass lesion either in the wall or due to an extrinsic lesion that prevented the passage of the endoscope. On examination, there was no gynecological pathology. Magnetic resonance imaging showed a mass, measuring 5.5 × 4 cm attached to the rectum posterior to the uterus. The ureter on that side was dilated. Surgically there was a pelvic mass adhered to the rectum and uterine adnexes, measuring 10 × 12 cm. It originated from uterine adnexes, particularly ones from the left side and formed a conglomerated mass with the uterus and nearby organs; the left ureter was also dilated due to the pelvic mass. Because of concomitant tubal abscess formation and difficulty in dissection planes, total abdominal hysterectomy and bilateral salphingo-oophorectomy was performed (our patient was 48 years old and had completed her childbearing period. The cytology revealed inflammatory cells with aggregates of Actinomyces. Penicillin therapy was given for six months without any complication. Conclusions Pelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intra-uterine devices, and who have a history of appendectomy, tonsillectomy

  19. Torsion and antero-posterior bending in the in vivo human tibia loading regimes during walking and running. (United States)

    Yang, Peng-Fei; Sanno, Maximilian; Ganse, Bergita; Koy, Timmo; Brüggemann, Gert-Peter; Müller, Lars Peter; Rittweger, Jörn


    Bending, in addition to compression, is recognized to be a common loading pattern in long bones in animals. However, due to the technical difficulty of measuring bone deformation in humans, our current understanding of bone loading patterns in humans is very limited. In the present study, we hypothesized that bending and torsion are important loading regimes in the human tibia. In vivo tibia segment deformation in humans was assessed during walking and running utilizing a novel optical approach. Results suggest that the proximal tibia primarily bends to the posterior (bending angle: 0.15°-1.30°) and medial aspect (bending angle: 0.38°-0.90°) and that it twists externally (torsion angle: 0.67°-1.66°) in relation to the distal tibia during the stance phase of overground walking at a speed between 2.5 and 6.1 km/h. Peak posterior bending and peak torsion occurred during the first and second half of stance phase, respectively. The peak-to-peak antero-posterior (AP) bending angles increased linearly with vertical ground reaction force and speed. Similarly, peak-to-peak torsion angles increased with the vertical free moment in four of the five test subjects and with the speed in three of the test subjects. There was no correlation between peak-to-peak medio-lateral (ML) bending angles and ground reaction force or speed. On the treadmill, peak-to-peak AP bending angles increased with walking and running speed, but peak-to-peak torsion angles and peak-to-peak ML bending angles remained constant during walking. Peak-to-peak AP bending angle during treadmill running was speed-dependent and larger than that observed during walking. In contrast, peak-to-peak tibia torsion angle was smaller during treadmill running than during walking. To conclude, bending and torsion of substantial magnitude were observed in the human tibia during walking and running. A systematic distribution of peak amplitude was found during the first and second parts of the stance phase.

  20. Anterior Hip Subluxation due to Lumbar Degenerative Kyphosis and Posterior Pelvic Tilt

    Directory of Open Access Journals (Sweden)

    Hiroyuki Tsuchie


    Full Text Available Nontraumatic anterior subluxation and dislocation of the hip joint are extremely rare. A 58-year-old woman presented to our outpatient clinic with left hip pain with a duration of 15 years. There was no history of trauma or other diseases. Her hip pain usually occurred only on walking and not at rest. Physical examinations demonstrated no tenderness in the hip joint. The range of motion of both hip joints was almost normal. Laxity of other joints was not observed. The bone mineral density of the lumbar spine and proximal femur confirmed a diagnosis of osteoporosis. A plain radiograph showed osteoarthritic changes of the hip joints, severe posterior pelvic tilt, and superior displacement of both femoral heads, especially in a standing position. Three-dimensional computed tomography (3DCT revealed anterior subluxation of both femoral heads. Seven years after the initial visit, both hip joints showed progression to severe osteoarthritis. Although the exact cause remains unclear, lumbar kyphosis, posterior pelvic tilt, and a decrease in acetabular coverage may have influenced the current case. We should be aware of these factors when we examine patients with hip osteoarthritis.

  1. Fatigue stress injuries of the pelvic bones and proximal femur: evaluation with MR imaging

Box 340, Haartmaninkatu 4, 00029 Helsinki (Finland)


    The purpose of this study was to determine the prevalence and the distribution as well as male/female differences in patients with hip or pelvic pain based on MRI results. Three hundred forty consecutive conscripts (45 women, 295 men; age range 18-29 years; mean age 20.7 years) suffering from stress-related hip, buttock or groin pain took part in the study. All 340 patients underwent MR imaging. Radiographic data were available for 215 patients. Two radiologists interpreted the images by consensus. In MRI 174 stress injuries were diagnosed in 137 patients (32 women, 105 men). The incidence of bone stress injuries in women was significantly higher than that in men (p<0.0001). One hundred five of the injuries (60%) were related to the proximal femur, 70 (67%) to the neck, 34 (32%) to the proximal shaft, and one (1%) to the head. Sixty-nine of the 174 stress injuries (40%) concerned the pelvic bones: sacrum 28 (41%); inferior pubic ramus 34 (49%); superior pubic ramus 3 (4%); iliac bone 3 (4%); and acetabulum 1 (1%). In 31 of the 174 cases (18%) symptoms were contralateral to MR findings. Thirty-three of the 137 patients (24%) had multiple bone stress injuries, 29 had two bone stress injuries and 4 patients had three. The sensitivity of radiography was 37%, specificity 79%, accuracy 60%, positive predictive value 59% and negative predictive value 61%. The kappa value for agreement between radiography and MRI was poor (0.17, p=0.0008). Patients suffering from stress-related hip pain MRI revealed bone stress injuries in 40%; of these, 60% were located in the proximal femur and 40% in the pelvic bones. For accurate diagnosis of bone stress injuries, and to ensure appropriate treatment, the entire pelvis and both proximal femurs should be studied simultaneously by means of MRI. (orig.)

  2. Sociopsychological factors in women with chronic pelvic pain with and without pelvic venous congestion. (United States)

    Fry, R P; Beard, R W; Crisp, A H; McGuigan, S


    Social and psychological factors have long been proposed as being of importance in a sizeable subgroup of women complaining of unexplained chronic pelvic pain (CPP). The aim of this study was to examine this in two subgroups of CPP patients, thereby eliminating pain alone as the determining variable. Consecutive attenders at a clinic for CPP were assessed on a range of somatic, historical, social, and psychological variables using detailed interviews and questionnaires. They were subsequently allocated to one of two groups, based on the presence or absence of pelvic venous congestion (PVC). Significant associations emerged between some social arrangements, paternal parenting, and patterns of hostility in the group with pelvic venous congestion. The groups also differed in patterns of family illness, and the congested group tended to report more childhood sexual abuse (CSA). Clear case definition in CPP is important. In the subgroup with pelvic venous congestion early social experience may play an important role. Father-daughter relationships may be particularly relevant. Hostility patterns may influence the development of the condition. CSA does not appear to play a specific role in all unexplained CPP cases, but may have relevance for the subgroup with pelvic venous congestion.

  3. Predicting lower third molar eruption on panoramic radiographs after cephalometric comparison of profile and panoramic radiographs. (United States)

    Begtrup, Anders; Grønastøð, Halldis Á; Christensen, Ib Jarle; Kjær, Inger


    Previous studies have suggested methods for predicting third molar tooth eruption radiographically. Still, this prediction is associated with uncertainty. The aim of the present study was to elucidate the association between cephalometric measurements on profile and panoramic radiographs and to find a simple and reliable method for predicting the eruption of the mandibular third molar by measurements on panoramic radiographs. The material consisted of profile and panoramic radiographs, taken before orthodontic treatment, of 30 males and 23 females (median age 22, range 18-48 years), with no known diseases. Cephalometric measurements on panoramic and profile radiographs were performed and compared, i.e. the size of the gonial angle and sagittal distance from the alveolar margin between the mandibular central incisors to the anterior border of the mandibular ramus. Furthermore, the mesiodistal width of the second molar was measured. Statistical methods included analysis of method error. The probability of eruption was modelled using logistic regression analysis. Correlation was observed between all measurements on profile and panoramic radiographs. The skeletal variable expressing the length from the ramus to the incisors (olr-id) showed a statistically significant correlation. By combining this length with the mesiodistal width of the lower second molar, the prediction of eruption of the lower third molar was strengthened. A new formula for calculating the probability of eruption of the mandibular third molar was made and a graph constructed for easy assessment. In conclusion, a simple method for predicting the eruption of the third molar is presented.

  4. [Anatomy of the pelvic lymphatic system]. (United States)

    Wolfram-Gabel, R


    The lymphatic system of the pelvis collects the lymph of the genital and urinary organs and of the digestive tract. It is formed by lymphatic nodes and vessels situated inside the conjunctive tissue, near the organs (visceral lymphatic nodes) but especially along the external, internal and common iliac vessels (iliac lymphatic nodes). These nodes receive afferent vessels issued from the different pelvic organs. From the iliac lymphnodes arise efferent vessels running towards lymphatic collectors, situated above them, and which end in the lymphatic lombar duct. The lymphatic pathways represent the preferential way of scattering of cancerous cells. Therefore, the knowledge of the anatomy, of the situation and of the draining of the nodes is of the utmost importance in the evaluation of a cancer of a pelvic organ.

  5. MR imaging of the female pelvic region. (United States)

    Olson, M C; Posniak, H V; Tempany, C M; Dudiak, C M


    Magnetic resonance (MR) imaging is a valuable technique for noninvasive evaluation of the female pelvic region. This article presents the normal anatomy and abnormalities of the female pelvis. MR imaging may be more useful than clinical evaluation or other imaging modalities in diagnosing or staging developmental anomalies, leiomyomas, adenomyosis, endometrial or cervical carcinoma, vaginal neoplasms, ovarian cysts, endometriosis, teratomas, polycystic ovaries, or other ovarian masses. It could potentially replace laparoscopy as a more useful tool in the diagnosis of uterine anomalies. MR imaging is generally capable of helping determine whether a pelvic mass is uterine or adnexal in origin and may be used to characterize some adnexal masses. In some cases, MR imaging is used to differentiate recurrent disease from posttreatment fibrosis, which aids in treatment planning.

  6. [Contraception and pelvic infection in women]. (United States)

    Keith, L; Berger, G S; Brown, E R


    Although sexually transmitted diseases are a major public health problem at the international level, the relationship between contraception and pelvic infection is seldom examined. Numerous STDs are more difficult to diagnose, more frequent, and more serious in women than in men. Differential diagnosis between pelvic infection and other intraabdominal syndromes has been a concern for practitioners for years, and many pelvic infections are probably never diagnosed. Lower abdominal pain and sensitivity as well as fever, leucocytosis, accelerated sedimentation rate, inflammatory annexial mass evident on sonography, and microorganisms in the pouch of Douglass and presence of leucocytes in the peritoneal fluid are diagnostic criteria. Apart from errors in treatment resulting from errors in diagnosis, pelvic infections are often inadequately treated, especially in the initial phase before symptoms are confirmed. The exact incidence of pelvic infections in the US is unknown, but pelvic inflammatory disease (PID) accounted for over 200,000 hospitalizations per year between 1970-75. PID carries grave risks of subsequent ectopic pregnancy, chronic pelvic pain, and infertility which is more likely as the number of acute episodes increases. The female genital tract has diverse microenvironments propitious for growth of microorganisms of different types, aerobic and anaerobic. Each anatomic site has specific features conditioning bacterial growth. Histological modifications during the menstrual cycle and pregnancy affect the microbial flora. Except in the case of gonorrhea, it is not known how many female lower genital tract infections spread to the upper tract. Since 1970, several studies have domonstrated a growing diversity of cervical and vaginal flora in asymptomatic subjects. The principal risk factors for PID have been well described in the literature. All contraceptive methods except the IUD provide some degree of protection against PID. Even among IUD users the risk of

  8. [Pelvic actinomycosis abscess and intrauterine device]. (United States)

    Ko-Kivok-Yun, P; Charasson, T; Halasz, A; Fournié, A


    A case of association between IUD and a left tubal actinomycotic abscess is presented. The 45 year old patient was wearing an IUD for five years. The symptomatology was mainly that of pelvic pain with an associated mass in the left iliac fossa. The working diagnosis was that of a digestive tumor or an adnexal mass. The surgical procedure allowed to identify an inflammatory reaction with a pseudotumoral abscess formation in the left fallopian tube. The etiology was confirmed by the pathology and bacteriology reports. Treatment consists in surgical extirpation of the infected structures and long term antibacterial therapy. Actinomycosis is a rare but potentially serious pelvic disease. It may involve various organs and readily takes on the aspect of tumor formation.

These tumors commonly arise from the cranial nerves as acoustic neurinomas but they are extremely rare in the pelvis and the retroperitoneal area (less than 0.5% of reported cases, unless they are combined with von Recklinghausen disease (type 1 neurofibromatosis. We report the case of a 58-year-old female with pelvic schwannoma, 6.5 × 5.5 cm in size, in the right parametrium. This is the first case reported in the literature. Based on the rarity of this tumor and in order to ensure optimum treatment and survival for our patient, we performed laparotomy with total abdominal hysterectomy and en-block tumor excision. A frozen section was taken during the surgery before complete resection of the mass, which was ambiguous. Because of the possibility of malignancy, complete excision of the mass was performed, with pelvic blunt dissection. Histological examination showed a benign neoplasm, originating from the cells of peripheral nerve sheaths; diagnosis was a schwannoma. There were degenerative areas, including cystic degeneration, hemorrhagic infiltrations, ischemic foci with pycnotic cells, and collagen replacement. Pelvic schwannomas are rare neoplasms that can be misdiagnosed. Laparoscopy is a safe

    Álvaro-Afonso, Francisco Javier; Lázaro-Martínez, José Luis; Aragón-Sánchez, Javier; García-Morales, Esther; García-Álvarez, Yolanda; Molines-Barroso, Raúl Juan


    The purpose of this study was to analyze the influence of radiographic arterial calcification (RAC) on the clinical interpretation of ankle-brachial index (ABI) values in patients with diabetic foot ulcers. We analyzed a retrospective clinical database of 60 patients with diabetic foot ulcers from the Diabetic Foot Unit (Complutense University, Madrid, Spain) between January 2012 and March 2014. For each patient, anteroposterior XR-plains were evaluated, and the ABI and toe-brachial index (TBI) were assessed by an experienced clinician. To analyze the correlation among quantitative variables, we applied the Pearson correlation coefficient. Fifty percent (n = 9/18) of our patients with a normal ABI and RAC had a TBI diabetic foot ulcers, or RAC.

  16. Tachykinin receptors in the equine pelvic flexure. (United States)

    Sonea, I M; Wilson, D V; Bowker, R M; Robinson, N E


    Tachykinins, of which substance P (SP) is the prototype, are neuropeptides which are widely distributed in the nervous systems. In the equine gut, SP is present in enteric nerves and is a powerful constrictor of enteric muscle; in other species, SP is also known to have potent vasodilatory and pro-inflammatory effects. The specific effects of SP are determined by the subtype of receptor present in the target tissue. There are 3 known subtypes of tachykinin receptors, distinguished by their relative affinities for SP and other tachykinins. The distribution of SP binding sites in the equine pelvic flexure was determined using 125I-Bolton Hunter SP (I-BHSP) autoradiography. Most I-BHSP binding sites were determined to be saturable and specific, therefore presumably representing tachykinin receptors. The greatest degree of I-BHSP binding occurred over very small vessels, and over the muscularis mucosae; I-BHSP binding was also intense over the circular muscle of the muscularis externa and mucosa, and present, although less intense, over the longitudinal muscle of the muscularis externa. Competition of I-BHSP with specific receptor agonists for binding sites in the equine pelvic flexure were used to determine the subtypes of tachykinin receptors present. The neurokinin-1 receptor subtype predominated in the equine pelvic flexure, followed by the neurokinin-3 receptor subtype.

  17. Pelvic radiation disease: Updates on treatment options (United States)

    Frazzoni, Leonardo; La Marca, Marina; Guido, Alessandra; Morganti, Alessio Giuseppe; Bazzoli, Franco; Fuccio, Lorenzo


    Pelvic cancers are among the most frequently diagnosed neoplasms and radiotherapy represents one of the main treatment options. The irradiation field usually encompasses healthy intestinal tissue, especially of distal large bowel, thus inducing gastrointestinal (GI) radiation-induced toxicity. Indeed, up to half of radiation-treated patients say that their quality of life is affected by GI symptoms (e.g., rectal bleeding, diarrhoea). The constellation of GI symptoms - from transient to long-term, from mild to very severe - experienced by patients who underwent radiation treatment for a pelvic tumor have been comprised in the definition of pelvic radiation disease (PRD). A correct and evidence-based therapeutic approach of patients experiencing GI radiation-induced toxicity is mandatory. Therapeutic non-surgical strategies for PRD can be summarized in two broad categories, i.e., medical and endoscopic. Of note, most of the studies have investigated the management of radiation-induced rectal bleeding. Patients with clinically significant bleeding (i.e., causing chronic anemia) should firstly be considered for medical management (i.e., sucralfate enemas, metronidazole and hyperbaric oxygen); in case of failure, endoscopic treatment should be implemented. This latter should be considered the first choice in case of acute, transfusion requiring, bleeding. More well-performed, high quality studies should be performed, especially the role of medical treatments should be better investigated as well as the comparative studies between endoscopic and hyperbaric oxygen treatments.

  18. Abdominal-Pelvic Actinomycosis Mimicking Malignant Neoplasm

    Directory of Open Access Journals (Sweden)

    Teresa Pusiol


    Full Text Available Abdominal-pelvic actinomycosis is often mistaken for other conditions, presenting a preoperative diagnostic challenge. In a 46-year-old female, computed tomography showed an abdominal-pelvic retroperitoneal mass extending from the lower pole of the right kidney to the lower pelvis. The patient had a 3-year history of intrauterine device. The mass appeared to involve the ascending colon, cecum, distal ileum, right Fallopian tube and ovary, and ureter anteriorly and the psoas muscle posteriorly. The resection of retroperitoneal mass, distal ileum appendicectomy, right hemicolectomy, and right salpingo-oophorectomy was performed. The postoperative period was uneventful. Penicillin therapy was given for six months without any complication. The retroperitoneal mass measured 4.5 × 3.5 × 3 cm, surrounded adjacent organs and histologically showed inflammatory granulomatous tissue, agglomeration of filaments, and sulfur granules of Actinomyces, with positive reaction with periodic acid Schiff. Right tubo-ovarian abscess was present. Abdominalpelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intrauterine device.

  19. Physical exercise and pelvic girdle pain in pregnancy

    DEFF Research Database (Denmark)

    Andersen, Linda Kahr; Backhausen, Mette; Hegaard, Hanne Kristine


    OBJECTIVE: Pelvic girdle pain is a frequent cause of sick leave among pregnant women in Denmark. Studies regarding prevention of pelvic girdle pain are sparse. The aim of this study was to examine the association between physical exercise and pelvic girdle pain in pregnancy. STUDY DESIGN: A nested...... case-control study within the Danish National Birth Cohort (n = 5304). METHODS: This study used self-reported data on pelvic girdle pain obtained from an interview six months after childbirth. Information on physical exercise was obtained from the pregnancy interview around gestational week 16....... The association was estimated using logistic regression analysis. RESULTS: Physical exercise in pregnancy was associated with decreased risk of overall pelvic girdle pain (OR = 0.87; 95% CI: 0.77-0.99, p = 0.028). Tests for trend indicated decreasing odds for pelvic girdle pain with increasing number of hours per...

  20. Roles of radiograph, magnetic resonance imaging, threedimensional computed tomography in early diagnosis of femoro-acetabular impingement in 17 cases

    GU Gui-shan; ZHU Dong; WANG Gang; WANG Cheng-xue


    Objective: To evaluate the roles of radiograph, magnetic resonance imaging (MRI), three-dimensional computed tomography (3-D CT) in early diagnosis of femoro-acetabular impingement (FAI) in 17 cases. Methods: Plain radiographs of the pelvis, 3-D CT, and MRI of the hip were made on 17 patients with groin pain, which was worse with prolonged sitting (i.e. hip flexion). There was no history of trauma or childhood hip disorders in the patients who did not complain of any other joint problems or neurologic symptoms. All patients had positive anterior or posterior impingement test. Plain radiographs included an antero-posterior (AP) view of the hip and a cross table lateral view with slight internal rotation of the hip. CT scan was performed with the Lightspeed 16 row spiral (General Electric Company, USA) at 1.25 mm slice reconstruction. MRI scan was performed on the Siemens Avanto (Siemens Company, Germany)1.5T supraconducfion magnetic resonance meter. The CT and MRI scans were taken from 1 cm above the acetabulum to the lesser trochanter in 5 series. Results: The plain radiographs of the pelvis showed that among the 17 patients, 12 (70.59%) had "Cam" change of the femoral head, 6 (35.29%) had positive "cross-over" sign, and 17 (100%) had positive "Pincer" change of the acetabulum. The 16 row spiral CT noncontrast enhanced scan and 3-D reconstruction could discover minus femoral offset and ossification and osteophyte of the acetabulum labrum in all the 17 cases (100%). The MRI noncontrast enhanced scan could discover more fluid in the hip joint in 15 cases (88.33%), subchondral ossification in 3 cases (17.6%), and labium tears in 3 cases (17.6%). Conclusions: Plain radiographs can provide the initial mainstay for the diagnosis of FAI, 3-D CT can tell us the femoral offset, while MRI can show labrum tears in the very early stage of FAI. Basically, X-ray examination is enough for the early diagnosis of FAI, but 3-D CT and MRI may be useful for the treatment.

  1. [Intrauterine device and pelvic tumor: two case reports of pelvic actinomycosis with pseudotumor from tropical zones]. (United States)

    Abid, M; Ben Amar, M; Damak, Z; Feriani, N; Guirat, A; Khebir, A; Mzali, R; Frikha, M F; Beyrouti, M I


    Pelvic actinomycosis is a rare chronic disease caused by actinomycete species. The pseudotumorous form is the most common and often leads to misdiagnosis. The purpose of this report is to describe two cases of pelvic actinomycosis involving women with a history of intrauterine contraceptive device (IUD) use. Diagnosis was based on pelvic mass and the findings of surgery undertaken for suspicion of an advanced ovarian tumor with hepatic metastasis in one case and for a tumor of the right ovary in the other case. Diagnosis was confirmed by histological examination of a biopsy specimen in the first case and of the surgical specimen (right ovariectomy) in the second case. Long-term antibiotic therapy was effective in both patients. Based on these two cases and review of the literature, discussion focuses on diagnostic pitfalls, natural course, and therapeutic options for this particular infection.

  2. Medical Treatments for Endometriosis-Associated Pelvic Pain



    The main sequelae of endometriosis are represented by infertility and chronic pelvic pain. Chronic pelvic pain causes disability and distress with a very high economic impact. In the last decades, an impressive amount of pharmacological agents have been tested for the treatment of endometriosis-associated pelvic pain. However, only a few of these have been introduced into clinical practice. Following the results of the controlled studies available, to date, the first-line treatment for endome...

    Peyman Varedi


    Full Text Available We report and discuss a case of primary hydatidosis of the pelvic cavity in a woman who presented with severe weight loss and abdominal pain. This unusual presentation was initially considered as a tumor process until surgical exploration and microscopic studies confirmed the diagnosis. The gynecologists should be aware of possibility of primary hydatid cyst of the pelvic cavity and should be considered in the differential diagnosis of cystic pelvic masses, especially in areas where the disease is endemic.

  4. Tactile Imaging Markers to Characterize Female Pelvic Floor Conditions. (United States)

    van Raalte, Heather; Egorov, Vladimir


    The Vaginal Tactile Imager (VTI) records pressure patterns from vaginal walls under an applied tissue deformation and during pelvic floor muscle contractions. The objective of this study is to validate tactile imaging and muscle contraction parameters (markers) sensitive to the female pelvic floor conditions. Twenty-two women with normal and prolapse conditions were examined by a vaginal tactile imaging probe. We identified 9 parameters which were sensitive to prolapse conditions (p pelvic floor prolapse.

  5. Radiodiagnosis of pelvic birth injuries and their consequences

    Energy Technology Data Exchange (ETDEWEB)

    Konycheva, E.A.; Loskutova, L.A. (Bashkirskij Meditsinskij Inst. (USSR))

    A study was made of the changes in the pelvic articulations in women with birth injuries 2-5 years following birth on the basis of the clinicoroentgenological findings. Pathological adhesion of birth injuries of the pelvic bones, that manifested itself in the formation of callus and arthrosis of the public and sacroiliac articulations, was noted. The study confirmed incomplete rehabilitation in this group of women. For prognosis of subsequent parturition roentgenopelvimetry is recommended for women with birth injuries of the pelvic girdle.

  6. Pelvic pain after childbirth: a longitudinal population study. (United States)

    Bjelland, Elisabeth Krefting; Owe, Katrine Mari; Pingel, Ronnie; Kristiansson, Per; Vangen, Siri; Eberhard-Gran, Malin


    In this longitudinal population study, the aims were to study associations of mode of delivery with new onset of pelvic pain and changes in pelvic pain scores up to 7 to 18 months after childbirth. We included 20,248 participants enrolled in the Norwegian Mother and Child Cohort Study (1999-2008) without preexisting pelvic pain in pregnancy. Data were obtained by 4 self-administered questionnaires and linked to the Medical Birth Registry of Norway. A total of 4.5% of the women reported new onset of pelvic pain 0 to 3 months postpartum. Compared to unassisted vaginal delivery, operative vaginal delivery was associated with increased odds of pelvic pain (adjusted odds ratio [OR]: 1.30; 95% confidence interval [CI]: 1.06-1.59). Planned and emergency cesarean deliveries were associated with reduced odds of pelvic pain (adjusted OR: 0.48; 95% CI: 0.31-0.74 and adjusted OR: 0.65; 95% CI: 0.49-0.87, respectively). Planned cesarean delivery, young maternal age, and low Symptom Checklist-8 scores were associated with low pelvic pain scores after childbirth. A history of pain was the only factor associated with increased pelvic pain scores over time (P = 0.047). We conclude that new onset of pelvic pain after childbirth was not commonly reported, particularly following cesarean delivery. Overall, pelvic pain scores were rather low at all time points and women with a history of pain reported increased pelvic pain scores over time. Hence, clinicians should follow up women with pelvic pain after a difficult childbirth experience, particularly if they have a history of pain.

  7. Osteology and radiographic anatomy of the pelvis and hind limb of healthy ring-tailed lemurs (Lemur catta). (United States)

    Makungu, M; Groenewald, H B; du Plessis, W M; Barrows, M; Koeppel, K N


    In family Lemuridae, anatomical variations exist. Considering its conservation status (near threatened) and presence of similarities between strepsirrhines and primitive animals, it was thought to be beneficial to describe the gross osteology and radiographic anatomy of the pelvis and hind limb of ring-tailed lemurs (Lemur catta) as a reference for clinical use and species identification. Radiography was performed in 14 captive adult ring-tailed lemurs. The radiographic findings were correlated with bone specimens from two adult animals. Additionally, computed tomography of the hind limbs was performed in one animal. The pelvic bone has a well-developed caudal ventral iliac spine. The patella has a prominent tuberosity on the cranial surface. The first metatarsal bone and digit 1 are markedly stouter than the other metatarsal bones and digits with medial divergence from the rest of the metatarsal bones and digits. Ossicles were seen in the lateral meniscus, inter-phalangeal joint of digit 1 and in the infrapatellar fat pad. Areas of mineral opacity were seen within the external genitalia, which are believed to be the os penis and os clitoris. Variations exist in the normal osteology and radiographic appearance of the pelvis and hind limb of different animal species. The use of only atlases from domestic cats and dogs for interpretative purposes may be misleading.

  8. Mediastinal hemorrhage: An evaluation of radiographic manifestations

    Energy Technology Data Exchange (ETDEWEB)

    Woodring, J.H.; Loh, F.K.; Kryscio, R.J.


    Eleven common radiographic signs of mediastinal hemorrhage were evaluated by two observers for the following three patient groups: normal subjects, patients with mediastinal hemorrhage and no arterial injury, and patients with major thoracic arterial injury. Supine chest radiographs were studied in all cases. Four major conclusions can be made based upon these finding. M/C ratio (mediastinal width to chest width), tracheal deviation, left hemothorax, paraspinal line widening, and aorto-pulmonary window opacification do not reliably separate these three groups of patients. The diagnosis of mediastinal hemorrhage may be made if the aortic contour is abnormal or if one of the following signs is positive: abnormal mediastinal width, apical cap, widening of the right paratracheal stripe, or deviation of the nasogastric tube. Due to interobserver variation, there is good agreement between observers for the following four signs only: transverse mediastinal width, tracheal deviation, nasogastric tube deviation, nasogastric tube deviation, and right paratracheal stripe widening.

    Full Text Available The temporomandibular joint has a very important role in the stomatognathic system. Its main function is for the opening and closing movement, mastication, and speech. It is located anterior to the ear. The temporomandibular joint connects maxilla and mandible through the articular fossa, hence the slightest change that happens would cause serious matters such as pain, exiting, speech disorder, difficulty in opening and closing movement, headache, and even trismus. In a child or an adolescent, the symptoms are often vague; everything is interpreted as “pain”. This is probably why temporomandibular disorder are often undetected by dentists. Therefore, patience and accuracy is needed to determine the actual disorder through means of clinical and radiographic examination. The radiographic examination suitable for child is the transcranial projection. This projection is believed to be more accurate amongst other projection for child patients.

  10. An enlarged sella turcica on cephalometric radiograph. (United States)

    Chang, H-P; Tseng, Y-C; Chou, T-M


    A 28-year-old male presented to the Orthodontic clinic for correction of his anterior crossbite due to mandibular prognathism as a result of pituitary adenoma with acromegaly. A radiographic cephalometric analysis and clinical orthodontic examination were made. This article describes in detail the methods of correcting the magnification of cephalometric linear measurements in sellar dimensions (length, depth and width) from lateral and posteroanterior cephalograms. Cephalometric findings revealed that the sella enlarged in all its dimensions with a deepening of the floor in this acromegalic case. We discuss the radiographic diagnosis of an enlarged sella turcica in intrasellar tumours and also emphasise the dentist's important role in the initial diagnosis of pituitary adenoma cases.

  11. Modeling the pelvic region for non-invasive pelvic intraoperative neuromonitoring

    Directory of Open Access Journals (Sweden)

    Moszkowski Tomasz


    Full Text Available Finite element analysis (FEA of electric current distribution in the pelvis minor may help to assess the usability of non-invasive surface stimulation for continuous pelvic intraoperative neuromonitoring. FEA requires generation of quality volumetric tetrahedral mesh geometry. This study proposes the generation of a suitable mesh based on MRI data. The resulting volumetric mesh models the autonomous nerve structures at risk during total mesorectal excision. The model also contains the bone, cartilage, fat, skin, muscle tissues of the pelvic region, and a set of electrodes for surface stimulation. The model is ready for finite element analysis of the discrete Maxwell’s equations.

  13. Isolated Pelvic Hyperthermochemotherapeutic Perfusion -An Experimental Study on Isolating Efficacy

    Institute of Scientific and Technical Information of China (English)


    Hyperthermochemotherapeutic perfusion model through isolated pelvic vessels was developed to evaluate the leakage of hyperthermia and drugs (such as adriamycin) from the isolated pelvic circulation to systemic circulation and its associated side/toxic effects. The isolated pelvic circulation was perfused through a femoral artery catheter with hyperthermic (48 ℃ to 55 ℃) adriamycin solution (50 μg/ml) for 30 min. The efflux was drained through a femoral vein catheter. And the pelvic temperature was kept at the level of 43±0.5 ℃. The temperature of pelvic circulation was kept at 4 ℃ to 5 ℃ greater than the systemic/core temperature. The adriamycin concentration of pelvic efflux was 12 to 46 folds of that of systemic serum. The difference between them was very significant (P<0.001). As the perfusion pressure was increased, which kept lower than the mean systemic artery pressure, the leakage of the adriamycin from the isolated pelvic circulation to systemic circulation was increased, but there was no significant difference between them (P>0.05). During isolated perfusion, the systemic blood dynamics remained stable and there were no organic injuries on the important organs. It was suggested that the isolating efficacy of the modality of isolated pelvic hyperthermochemotherapeutic perfusion through vessels was rather high. The hyperthermia and drugs could be effectively limited in the isolated pelvic region with minor side effects on the systemic circulation and important organs.

    Use of a coded source facilitates high-resolution neutron imaging but requires that the radiographic data be deconvolved. In this paper, we compare direct deconvolution with two different iterative algorithms, namely, one based on direct deconvolution embedded in an MLE-like framework and one based on a geometric model of the neutron beam and a least squares formulation of the inverse imaging problem.

    A prototype video image display system, a real-time analog enhancer (RAE), was compared to conventional viewing conditions with the use of nonscreen dental films. When medium optical density films were evaluated, there was no significant difference in the number of radiographic details detected. Conventional viewing conditions allowed perception of more details when dark films were evaluated; however, the RAE unit allowed the perception of more details when light films were viewed.

  16. Nosocomial Legionnaires’ Disease: Clinical and Radiographic Patterns

    Directory of Open Access Journals (Sweden)

    Thomas J Marrie


    Full Text Available From 1981 to 1991, 55 patients (33 males, 22 females, mean age 58.6 years with nosocomial Legionnaires’ disease were studied. The mortality rate was 64%. One-half of the patients developed nosocomial Legionnaires’ disease within three weeks of admission. A surprising clinical feature was the low rate of findings of consolidation on physical examination, despite the fact that 52% of patients had this finding on chest radiograph. More than one-half of patients had pre-existing lung disease, rendering a radiographic diagnosis of pneumonia due to Legionella pneumophila impossible in 16% of cases despite microbiological confirmation. Nineteen per cent of patients who had blood cultures done had a pathogen other than L pneumophila isolated, suggesting dual infection in at least some of the patients. When the clinical and radiographic findings were combined it was noted that 40% of patients had one of three patterns suggestive of nosocomial Legionnaires’ disease: rapidly progressive pneumonia, lobar opacity and multiple peripheral opacities. However, in 60% of patients there were no distinctive features.

  17. Elongated Styloid Process - A Radiographic Study

    Directory of Open Access Journals (Sweden)

    Vajendra Joshi


    Full Text Available Eagle′s syndrome, also known as elongated styloid process syndrome, is a condition that may be the source of craniofacial and cervical pain. The styloid process is a slender bony projection arising from the lower surface of the petrous portion of the temporal bone. It has been estimated that between 2% to 28% of the general adult population has radiographic evidence of elongated styloid process. In adults, the mean radiographic length of the styloid process is 20 to 30 mm and its tip is located between the external and internal carotid arteries, just lateral to the tonsillar fossa. This study was done to evaluate the elongation of the styloid process and/or ligament ossification by using panoramic radiographs. Both ossification of stylohyoid and stylomandibular ligaments and truly elongated styloid process were defined as elongated styloid process. Elongated styloid processes should be kept in mind when the clinician is faced with oropharyngeal/ maxillary pain originating from impacted or unerupted third molars or dental caries.

  18. Radiographic adenoid evaluation - suggestion of referral parameters

    Directory of Open Access Journals (Sweden)

    Murilo F.N. Feres


    Full Text Available OBJECTIVE: this study aimed to evaluate the usefulness of current radiographic measurements, which were originally conceived to evaluate adenoid hypertrophy, as potential referral parameters. METHODS: children aged from 4 to 14 years, of both genders, who presented nasal obstruction complaints, were subjected to cavum radiography. Radiographic examinations (n = 120 were evaluated according to categorical and quantitative parameters, and data were compared to gold-standard videonasopharyngoscopic examination, regarding accuracy (sensitivity, negative predictive value, specificity, and positive predictive value. RESULTS: radiographic grading systems presented low sensitivity for the identification of patients with two-thirds choanal space obstruction. However, some of these parameters presented relatively high specificity rates when three-quarters adenoid obstruction was the threshold of interest. Amongst the quantitative variables, a mathematical model was found to be more suitable for identifying patients with more than two-thirds obstruction. CONCLUSION: this model was shown to be potentially useful as a screening tool to include patients with, at least, two-thirds adenoid obstruction. Moreover, one of the categorical parameters was demonstrated to be relatively more useful, as well as a potentially safer assessment tool to exclude patients with less than three-quarters obstruction, to be indicated for adenoidectomy.

    Schneider, Benjamin; Chevallier, Christine; Dominguez, Alejandro; Bruguier, Christine; Elandoy, Cristèle; Mangin, Patrice; Grabherr, Silke


    Multidetector computed tomography is becoming more widespread in forensic medicine. In most services, autopsy assistants perform the radiological examination. We introduced professional radiographers into the legal medicine service and hypothesized they would also be able to take over duties currently reserved for other specialists. The aims of this study were to evaluate if radiographers could be trained as "forensic radiographers" by (1) integrating graduated medical radiographers into the legal medicine service, (2) investigating the advantages of this collaboration, and (3) defining the duties of the forensic radiographers.The study was performed prospectively on a group of 8 recruited radiographers who underwent a testing period with special training. They learned the basics of medicolegal case treatment, the autonomous execution of postmortem computed tomography angiography, and postprocessing of data. Seven of 8 radiographers finished the training and were integrated into our service. Although all radiographers were able to fulfill the duties demanded after the training period, some radiographers could not enter or complete the program because they were unable to work with dead bodies.Our study presents the advantages of integrating radiographers into the medicolegal team and proposes how to train the forensic radiographers. In addition, the duties and responsibilities of these new specialists are defined.

    In spite of the widespread availability of CT scanners, conventional X-ray radiographs remain the basic imaging modality in patients with pelvic and/or acetabular trauma. However, the extent of their use will depend on local utilities (e.g., availability of CT scanners) and on the patient's clinical condition. Regarding the inaccuracy of conventional radiography in the diagnosis of injuries of the dorsal pelvic ring and of the acetabulum, computed tomography represents the most important imaging modality in the clinically stable patient. CT provides an exact staging of the extent of trauma and allows for differentiation of pelvic instabilities. CT clearly demonstrates the severity of acetabular trauma and is superior in the detection of local complicating factors, i.e., impressions fractures and (sub-)luxations of the femoral head as well as free intraarticular fragments. CT findings provide the basis for definite treatment regimens of the injured patient. By extension of the examination, all relevant organs and systems (craniospinal, cardiovascular, gastrointestinal, respiratory, genitourinary) can be imaged during one session. The speed of spiral CT scanners and their diagnostic accuracy will play a major role in the management of, especially, polytraumatized patients. The indication for angiography with the option of therapeutic embolization exists if a pelvic bleeding persists even after reposition and operative fixation of the injury. (orig.)

  2. Prediction of Incident Major Osteoporotic and Hip Fractures by Trabecular Bone Score (TBS) and Prevalent Radiographic Vertebral Fracture in Older Men. (United States)

    Schousboe, John T; Vo, Tien; Taylor, Brent C; Cawthon, Peggy M; Schwartz, Ann V; Bauer, Douglas C; Orwoll, Eric S; Lane, Nancy E; Barrett-Connor, Elizabeth; Ensrud, Kristine E


    Trabecular bone score (TBS) has been shown to predict major osteoporotic (clinical vertebral, hip, humerus, and wrist) and hip fractures in postmenopausal women and older men, but the association of TBS with these incident fractures in men independent of prevalent radiographic vertebral fracture is unknown. TBS was estimated on anteroposterior (AP) spine dual-energy X-ray absorptiometry (DXA) scans obtained at the baseline visit for 5979 men aged ≥65 years enrolled in the Osteoporotic Fractures in Men (MrOS) Study and its association with incident major osteoporotic and hip fractures estimated with proportional hazards models. Model discrimination was tested with Harrell's C-statistic and with a categorical net reclassification improvement index, using 10-year risk cutpoints of 20% for major osteoporotic and 3% for hip fractures. For each standard deviation decrease in TBS, there were hazard ratios of 1.27 (95% confidence interval [CI] 1.17 to 1.39) for major osteoporotic fracture, and 1.20 (95% CI 1.05 to 1.39) for hip fracture, adjusted for FRAX with bone mineral density (BMD) 10-year fracture risks and prevalent radiographic vertebral fracture. In the same model, those with prevalent radiographic vertebral fracture compared with those without prevalent radiographic vertebral fracture had hazard ratios of 1.92 (95% CI 1.49 to 2.48) for major osteoporotic fracture and 1.86 (95% CI 1.26 to 2.74) for hip fracture. There were improvements of 3.3%, 5.2%, and 6.2%, respectively, of classification of major osteoporotic fracture cases when TBS, prevalent radiographic vertebral fracture status, or both were added to FRAX with BMD and age, with minimal loss of correct classification of non-cases. Neither TBS nor prevalent radiographic vertebral fracture improved discrimination of hip fracture cases or non-cases. In conclusion, TBS and prevalent radiographic vertebral fracture are associated with incident major osteoporotic fractures in older men independent of each other

    The results of the examination and treatment of 16 patients aged from 26 to 46 years with persistent urinary disorders and chronic pelvic pain due to severe pelvic varicose veins are presented. Using ultrasound with color Doppler mapping and venography of renal and ovarian vein for evaluation of condition of the venous system of the pelvis, the significant dilation of the internal iliac, ovarian and uterine veins with a pronounced decrease in blood flow in veins up to the stasis of blood, accompanied by flow turbulence and powerful backflow of renal blood through ovarian veins were found in all patients. According to uroflowmetry, there was a decrease in detrusor tone and a violation of evacuation capacity of the bladder. Evaluation of microcirculation using LDF allowed to diagnose congestive hemodynamic type of microcirculation. Scleroembolization for varicose ovarian vein with Gianturco coil and ethoxysclerol was performed in all patients. Positive therapeutic effect in the form of eliminating varicose pelvic veins, pain relieve, disappearance of persistent dysuria, and the remission of chronic cystitis was achieved in 86% of women. This intervention provided the normal outflow of blood from the pelvic veins, contributed to the normalization of uroflowmetry data and restoration of normal microcirculation in the urinary bladder.

  5. Laparoscopic pelvic sling placement facilitates optimum therapeutic radiotherapy delivery in the management of pelvic malignancy.

    LENUS (Irish Health Repository)

    Joyce, M


    BACKGROUND: Radiotherapy has a significant role in the management of pelvic malignancies. However, the small intestine represents the main dose limiting organ. Invasive and non-invasive mechanical methods have been described to displace bowel out of the radiation field. We herein report a case series of laparoscopic placement of an absorbable pelvic sling in patients requiring pelvic radiotherapy. METHODS: Six patients were referred to our minimally invasive unit. Four patients required radical radiotherapy for localised prostate cancer, one was scheduled for salvage localised radiotherapy for post-prostatectomy PSA progression and one patient required adjuvant radiotherapy post-cystoprostatectomy for bladder carcinoma. All patients had excessive small intestine within the radiation fields despite the use of non-invasive displacement methods. RESULTS: All patients underwent laparoscopic mesh placement, allowing for an elevation of small bowel from the pelvis. The presence of an ileal conduit or previous surgery did not prevent mesh placement. Post-operative planning radiotherapy CT scans confirmed displacement of the small intestine allowing all patients to receive safely the planned radiotherapy in terms of both volume and radiation schedule. CONCLUSION: Laparoscopic mesh placement represents a safe and efficient procedure in patients requiring high-dose pelvic radiation, presenting with unacceptable small intestine volume in the radiation field. This procedure is also feasible in those that have undergone previous major abdominal surgery.

    Chirivella, Praveen; Singaraju, Gowri Sankar; Mandava, Prasad; Reddy, V Karunakar; Neravati, Jeevan Kumar; George, Suja Ani


    Objective: To test the null hypothesis that there is no effect of esthetic perception of smiling profile in three different facial types by a change in the maxillary incisor inclination and position. Materials and Methods: A smiling profile photograph with Class I skeletal and dental pattern, normal profile were taken in each of the three facial types dolichofacial, mesofacial, and brachyfacial. Based on the original digital image, 15 smiling profiles in each of the facial types were created using the FACAD software by altering the labiolingual inclination and anteroposterior position of the maxillary incisors. These photographs were rated on a visual analog scale by three panels of examiners consisting of orthodontists, dentists, and nonprofessionals with twenty members in each group. The responses were assessed by analysis of variance (ANOVA) test followed by post hoc Scheffe. Results: Significant differences (P < 0.001) were detected when ratings of each photograph in each of the individual facial type was compared. In dolichofacial and mesofacial pattern, the position of the maxillary incisor must be limited to 2 mm from the goal anterior limit line. In brachyfacial pattern, any movement of facial axis point of maxillary incisors away from GALL is worsens the facial esthetics. The result of the ANOVA showed differences among the three groups for certain facial profiles. Conclusion: The hypothesis was rejected. The esthetic perception of labiolingual inclination and anteroposterior of maxillary incisors differ in different facial types, and this may effect in formulating treatment plans for different facial types.

    Full Text Available The periprosthetic fracture of the acetabulum is a rare injury, and its management is only sporadically reported in the literature. A few case reports are available which mainly focus on periprosthetic acetabular fractures in the elderly population. In our case, a 32-year-old patient suffered from a periprosthetic acetabular fracture in combination with a pelvic ring injury following a high velocity accident. The fracture morphology allowed a salvage of the prosthesis with an open reduction and internal fixation with a good radiographic and functional outcome one year after trauma.

    Normative references for radiographic measurements commonly used in the diagnosis of developmental dysplasia of the hip at skeletal maturity are incomplete. The present study therefore aimed to establish new gender-specific standards for measurements reflecting the acetabular morphology, namely Sharp's angle, the acetabular roof angle of Toennis (AA) and the acetabular depth-width ratio (ADR), and measurements reflecting the position of the femoral head related to the acetabulum, namely the center-edge (CE) angle of Wiberg, the refined CE angle of Ogata, and the femoral head extrusion index (FHEI). The joint space width (JSW) is also reported. The population-based 1989 Bergen Birth Cohort (n = 3,935) was invited at age 19 years to a follow-up during 2007-09, of which 2,038 (52 %) attended. A standardized antero-posterior radiograph was assessed. The normative references are presented as mean {+-} standard deviation (SD) and 2.5-97.5 percentiles with 95 % confidence intervals. A total of 2,011 (841 males, 1,170 females, mean age 18.6 (SD 0.6)) radiographs were analyzed. Sharp's angle was 38.8 {+-} 3.5 in males and 40.7 {+-} 3.5 in females, with 97.5 percentiles of 46 and 47 , respectively. The CE angle was 32.1 {+-} 6.1 in males and 31.0 {+-} 6.1 in females, with 2.5 percentiles of 21 and 20 , respectively. The FHEI was 86.0 % {+-} 6.3 % in males and 85.6 % {+-} 6.6 % in females, with 2.5 percentiles of 74 and 73 , respectively. Updated gender-specific reference ranges for radiographic measurements commonly used for hip dysplasia at skeletal maturity are reported, similar to or slightly wider than those described in the literature. Statistically significant gender differences have been confirmed for most of the measurements. (orig.)

  10. The etiology of pelvic inflammatory disease. (United States)

    Keith, L; Berger, G S


    The etiology of pelvic inflammatory disease (PID) is speculated upon based on reported incidence and epidemiological studies. In Western society, the incidence of PID (annual) is 1% among women aged 15-34 years and 2% in the high risk group of women aged 15-24 years. The annual incidence in the US is higher, at least 2% among fecund sexually active women aged 13-44 years. The medical consequences of PID are infertility, ectopic pregnancy, and chronic pelvic pain. Causative agents include Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma hominis and various other aerobic and anaerobic microorganisms; however, the natural genital flora of females is so varied that determining actual causative agents is difficult. some case-control studies have determined risk factors for PID; these include particularly current or prior use of IUD, prior pelvic surgery, sexual activity (including number of partners), race, and prior PID acute infection. PID is not a sexually transmitted disease, but rather is classified as sexually derived. Use of barrier methods and oral contraceptives protects against PID. IUD use greatly increases the risk of PID, probably because of the avenue the device provides for organisms to ascend from the lower to the upper genital tract. The role of males in PID etiology is currently the subject of much discussion. It is theorized that the mechanical action of penis insertion in intercourse helps to move causative agents to the upper genital region; also, semen may carry vaginal flora through the cervical opening into the uterus and tubes. Menstruation and PID are closely associated, perhaps because the cervix dilates during bleedings. Research areas include: determination of role of sexual activity (and number of partners) in PID etiology; evaluation of events of menstruation that are predisposing; evaluation of relationship between bacteriosperma and lower and upper genital infections; relationship of particular contraceptive methods to PID

  11. Pelvic Incidence in Patients with Hip Osteoarthritis

    Ibrahim Raphael


    Full Text Available Background: Hip osteoarthritis (OA is a major cause of pain and disability that results in considerable social and medical costs. Mechanics such as posture, alignment and orientation of the hips and the spinal column and the relationship between these factors have been implicated in the development of both hip and spine pathologies. This study aims to test the hypothesis if pelvic incidence varies in patients with and without osteoarthritis. We assessed the relationship between spinopelvic alignment as measured by pelvic incidence (PI and the presence of hip OA. Methods: We collected supine pelvis CT scans of 1,012 consecutive patients not known to have hip OA. Our first group consisted of 95 patients with moderate to severe hip OA as per radiology reports. The second group included 87 patients with no evidence of hip OA. Power analysis revealed the need for 77 patients per group to find a mean difference in PI of 5º or less between both groups. Two trained physicians independently measured the PI to account for inter-observer reliability. Results: Patients with moderate to severe hip OA had a mean PI of 56.5º±12.8º. The mean PI for patients without hip OA was 57.2º±7.5º. An independent samples t-test revealed no significant difference between the PI values of the two groups. Spearman’s correlation coefficient of 0.754 demonstrated a high inter-observer reliability. Conclusion: There was no difference in PI angle of hip OA patients and "healthy" patients. Our measurements of patients without OA were almost identical to the reported normal PI values in the literature. It appears that hip OA is not associated with PI angle, refuting the hypothesis made in previous studies, stating that elevated PI contributes to the future development of hip arthritis. CT scan seems to be a reliable and accurate way of assessing pelvic incidence.

    Purpose:To enhance the awareness of rare complications of pelvic fracture and describe the correct diagnosis and effective treatment.Methods:A total of 188 cases of pelvic fractures were retrospectively reviewed,and four patients who suffered from four types of rare pelvic fracture complications were described,namely ureteral obstruction caused by retroperitoneal hematoma-induced abdominal compartment syndrome (ACS),bowel entrapment,external iliac artery injury,and open scrotal sac injury.Results:We demonstrated that combined measures should be employed to prevent the occurrence of ACS following major pelvic fractures.Ureteral catheter support may be a good option at an early stage when ACS occurred.Contrasted computed tomography examination and sufficient awareness are keys to a correct diagnosis of bowel entrapment following pelvic fractures.Recognition of risk factors,early diagnosis,and prompt treatment of suspected injury of the external iliac artery are keys to patient survival and to avoid limb loss.Scrotal and/or testicular injury complicated by pelvic fractures should be carefully treated to maintain normal gonad function.Additionally, establishment of a sophisticated trauma care system and multi-disdplinary coordination are important for correct diagnosis and treatment of rare complications in pelvic fractures.Conclusions:Rare complications of pelvic fractures are difficult to diagnose and negatively impact outcome.Recognition of risk factors and sufficient awareness are essential for correct diagnosis and prompt treatment.

  17. Pelvic girdle shape predicts locomotion and phylogeny in batoids. (United States)

    Ekstrom, Laura J; Kajiura, Stephen M


    In terrestrial vertebrates, the pelvic girdle can reliably predict locomotor mode. Because of the diminished gravitational effects on positively buoyant bony fish, the same relationship does not appear to exist. However, within the negatively buoyant elasmobranch fishes, benthic batoids employ pelvic fin bottom-walking and punting as primary or supplementary forms of locomotion. Therefore, in this study, we employed geometric and linear morphometrics to investigate if their pelvic girdles exhibit shape characteristics similar to those of sprawling terrestrial vertebrates. We tested for correlates of pelvic girdle shape with 1) Order, 2) Family, 3) Swim Mode, and/or 4) Punt Mode. Landmarks and semilandmarks were placed along outlines of dorsal views of 61 batoid pelvic girdles (3/3 orders, 10/13 families, 35/72 genera). The first three relative warps explained 88.45% of the variation among individuals (P girdle, was significantly different among punt modes, whereas only pectoral fin oscillators had differently shaped pelvic girdles when compared with batoids that perform other swimming modes (P girdles of batoids vary greatly, and therefore, likely function in ways not previously described in teleost fishes. This study illustrates that pelvic girdle shape is a good predictor of punt mode, some forms of swimming mode, and a species' Order. Such correlation between locomotor style and pelvic girdle shape provides evidence for the convergent evolution of morphological features that support both sprawled-gait terrestrial walking and aquatic bottom-walking.

    A 48-year-old woman developed symptomatic superior and inferior pubic rami fractures with a concomitant subluxation of the ipsilateral sacroiliac joint three years after pelvic irradiation for a gynecologic malignancy. Pathologic pelvic fractures (PPF) caused by irradiation may be difficult to distinguish from those caused by metastatic disease. PPF produce prolonged disability.

  1. Effect of pelvic tilt on lumbar spine geometry. (United States)

    Delisle, A; Gagnon, M; Sicard, C


    The purpose of this study was to use a noninvasive method to determine the effect of pelvic tilt on the lumbar spine geometry in the sagittal plane. Five healthy male subjects were instructed in performing active forward and backward pelvic tilt manoeuvres in the standing position. The lumbar spine geometry (severity of lordosis, pelvis and lumbar vertebrae orientations) was estimated with a lumbar spine geometric model. The voluntary backward pelvic tilt succeeded in reducing the depth of the lumbar spine curvature, but the forward tilt did not change it. Both pelvic tilt manoeuvres influenced the absolute orientations of the lower lumbar vertebrae and the relative orientations of some lumbar vertebrae. Interestingly, the L5/S1 joint showed was little affected by the pelvic tilt manoeuvres.

  2. Effect of pelvic floor muscle exercises on pulmonary function (United States)

    Han, DongWook; Ha, Misook


    [Purpose] This study aimed to determine the correlation between pelvic floor muscle strength and pulmonary function. In particular, we examined whether pelvic floor muscle exercises can improve pulmonary function. [Subjects] Thirty female college students aged 19–21 with no history of nervous or musculoskeletal system injury were randomly divided into experimental and control groups. [Methods] For the pulmonary function test, spirometry items included forced vital capacity and maximal voluntary ventilation. Pelvic floor muscle exercises consisted of Kegel exercises performed three times daily for 4 weeks. [Results] Kegel exercises performed in the experimental group significantly improved forced vital capacity, forced expiratory volume in 1 second, PER, FEF 25–75%, IC, and maximum voluntary ventilation compared to no improvement in the control group. [Conclusion] Kegel exercises significantly improved pulmonary function. When abdominal pressure increased, pelvic floor muscles performed contraction at the same time. Therefore, we recommend that the use of pelvic floor muscle exercises be considered for improving pulmonary function. PMID:26644681

  3. Small bowel obstruction in percutaneous fixation of traumatic pelvic fractures

    Directory of Open Access Journals (Sweden)

    Roberto Bini


    Full Text Available The use of external fixation for the initial treatment of unstable, complex pelvic injuries with hemodynamic instability remains an effective treatment for multiply injured patients. Bowel entrapment within a pelvic fracture is a rarely reported, potentially fatal complication. Here, we report a polytrauma patient with pelvic fractures who developed an intestinal obstruction after an external fixation. At an explorative laparotomy, we found an ileum segment trapped in the sacral fracture. Reported cases of bowel entrapment in pelvic fractures, especially in sacral fractures, are exceedingly rare. The diagnosis is often delayed due to difficulty distinguishing entrapment from the more common adynamic ileus. In conclusion, clinicians and radiologists should be aware of this potentially lethal complication of pelvic fractures treatment. To exclude bowel entrapment, patients with persistent ileus or sepsis should undergo early investigations.

    KPP Abhilash


    Full Text Available Background and Rationale: Respiratory system involvement in scrub typhus is seen in 20–72% of patients. In endemic areas, good understanding and familiarity with the various radiologic findings of scrub typhus are essential in identifying pulmonary complications. Materials and Methods: Patients admitted to a tertiary care center with scrub typhus between October 2012 and September 2013 and had a chest X ray done were included in the analysis. Details and radiographic findings were noted and factors associated with abnormal X-rays were analyzed. Results: The study cohort contained 398 patients. Common presenting complaints included fever (100%, generalized myalgia (83%, headache (65%, dyspnea (54%, cough (24.3%, and altered sensorium (14%. Almost half of the patients (49.4% had normal chest radiographs. Common radiological pulmonary abnormalities included pleural effusion (14.6%, acute respiratory distress syndrome (14%, airspace opacity (10.5%, reticulonodular opacities (10.3%, peribronchial thickening (5.8%, and pulmonary edema (2%. Cardiomegaly was noted in 3.5% of patients. Breathlessness, presence of an eschar, platelet counts of 2 mg/dL had the highest odds of having an abnormal chest radiograph. Patients with an abnormal chest X-ray had a higher requirement of noninvasive ventilation (odds ratio [OR]: 13.98; 95% confidence interval CI: 5.89–33.16, invasive ventilation (OR: 18.07; 95% CI: 6.42–50.88, inotropes (OR: 8.76; 95% CI: 4.35–17.62, higher involvement of other organ systems, longer duration of hospital stay (3.18 ± 3 vs. 7.27 ± 5.58 days; P< 0.001, and higher mortality (OR: 4.63; 95% CI: 1.54–13.85. Conclusion: Almost half of the patients with scrub typhus have abnormal chest radiographs. Chest radiography should be included as part of basic evaluation at presentation in patients with scrub typhus, especially in those with breathlessness, eschar, jaundice, and severe thrombocytopenia.

    You, Dong Soo [Department of Oral Radiology, College of Dentistry, Seoul National University, Seoul (Korea, Republic of)


    The author analysed the bone changes, the positional relationships between condylar head and articular fossa, and the interrelationship between the bone changes and the abnormal position of condylar head, from 1,036 radiographs of 259 patients with temporomandibular joint arthrosis, which were obtained by the oblique-lateral transcranial projection and orthopantomograms. The results were as follows: 1. Among the radiographic bone changes of the temporomandibular joint arthrosis, deformity was 36..90% (217 cases), sclerosis 34.18% (201 cases), erosive change 25.58% (152 cases) and marginal proliferation 3.06% (18 cases) respectively. 2. In the positional changes between condylar head and articular fossa, the downward positioning of condylar head in centric occlusion was most frequent (36.90%), of which frequency was significantly higher than forward positioning (11.22%) and backward positioning (4.76%) in same condition. Also, radiographs showed that the enlargement of articular space showed higher frequency than its narrowing. In the opening position of mouth, the restrict ed movement of condylar head within articular fossa was most frequent (35.03%). The forward positioning and the downward positioning was 15.65% and 9.52% respectively. Also, radiographs revealed that the incomplete movement or no positional change of condylar head was most frequent. 3. In the interrelationship between bone changes and abnormal position of condylar head, deformity was 42.79% in the cases of downward positioning of condylar head in centric occlusion and 37.50% in those of normal positioning of condylar head in same condition. This revealed that deformity was most frequent bone change in above condylar positionings. However, erosive change was 34.62% in the cases of downward positioning of condylar head in centric occlusion and 33 .33% in those of forward positioning. In opening position of condylar head, and deformity in the cases of norma l positioning, forward positioning and

    Full Text Available Effective diagnostic accuracy has in some way been the missing link between periodontal diagnosis and treatment. Most of the clinicians rely on the conventional two-dimensional (2D radiographs. But being a 2D image, it has its own limitations. 2D images at times can give an incomplete picture about the severity or type of disease and can further affect the treatment plan. Cone beam computed tomography (CBCT has a better potential for detecting periodontal bone defects with accuracy. The purpose here is to describe how CBCT imaging is beneficial in accurate diagnosis and will lead to a precise treatment plan.

  8. Clinical assessment of the impact of pelvic pain on women. (United States)

    Chalmers, K Jane; Catley, Mark J; Evans, Susan F; Moseley, G Lorimer


    We aimed to develop a questionnaire that assesses the impact of pelvic pain on women, regardless of diagnosis, that has high utility, sound psychometric performance, easy scoring, and high reliability. Two studies, with 3 separate cohorts, were undertaken. Both studies were completed online. Studies included women with self-reported pelvic pain. Women were eligible to participate regardless of whether their pelvic pain was undiagnosed, self-diagnosed, or diagnosed by a clinician. Study 1 used a 3-round "patient-as-expert" Delphi technique. These rounds defined the 10 aspects of life with the self-reported greatest impact on the lives of women with pelvic pain, which formed the questionnaire. Study 2 used Rasch analysis to assess the psychometric properties of the resultant 10-item questionnaire. To assess its reliability, a subgroup completed the questionnaire 3 times over a 3-week period. In study 1, 443 women with pelvic pain participated. The resultant 10-item questionnaire consisted of 8 Likert questions and 2 supplemental, nonscored questions. In study 2, 1203 women with pelvic pain completed the questionnaire. Rasch analysis showed that the questionnaire targeted the pelvic pain population well, had appropriate Likert categories, constituted a unidimensional scale, and showed internal consistency. Twenty-seven women with pelvic pain completed the reliability trial. Test-retest reliability was high (intraclass correlation coefficient 0.91, P Pelvic Pain Impact Questionnaire assesses the life impact of pelvic pain. It uses patient-generated language, is easily administered and scored, has very strong psychometric properties, and it is suitable for research and clinical settings across primary, secondary, and tertiary care.

    Richard L. Sweet


    Full Text Available Pelvic inflammatory disease (PID, one of the most common infections in nonpregnant women of reproductive age, remains an important public health problem. It is associated with major long-term sequelae, including tubal factor infertility, ectopic pregnancy, and chronic pelvic pain. In addition, treatment of acute PID and its complications incurs substantial health care costs. Prevention of these long-term sequelae is dependent upon development of treatment strategies based on knowledge of the microbiologic etiology of acute PID. It is well accepted that acute PID is a polymicrobic infection. The sexually transmitted organisms, Neisseria gonorrhoeae and Chlamydia trachomatis, are present in many cases, and microorganisms comprising the endogenous vaginal and cervical flora are frequently associated with PID. This includes anaerobic and facultative bacteria, similar to those associated with bacterial vaginosis. Genital tract mycoplasmas, most importantly Mycoplasma genitalium, have recently also been implicated as a cause of acute PID. As a consequence, treatment regimens for acute PID should provide broad spectrum coverage that is effective against these microorganisms.

  14. Gluteal Compartment Syndrome Secondary to Pelvic Trauma. (United States)

    Diaz Dilernia, Fernando; Zaidenberg, Ezequiel E; Gamsie, Sebastian; Taype Zamboni, Danilo E R; Carabelli, Guido S; Barla, Jorge D; Sancineto, Carlos F


    Gluteal compartment syndrome (GCS) is extremely rare when compared to compartment syndrome in other anatomical regions, such as the forearm or the lower leg. It usually occurs in drug users following prolonged immobilization due to loss of consciousness. Another possible cause is trauma, which is rare and has only few reports in the literature. Physical examination may show tense and swollen buttocks and severe pain caused by passive range of motion. We present the case of a 70-year-old man who developed GCS after prolonged anterior-posterior pelvis compression. The physical examination revealed swelling, scrotal hematoma, and left ankle extension weakness. An unstable pelvic ring injury was diagnosed and the patient was taken to surgery. Measurement of the intracompartmental pressure was measured in the operating room, thereby confirming the diagnosis. Emergent fasciotomy was performed to decompress the three affected compartments. Trauma surgeons must be aware of the possibility of gluteal compartment syndrome in patients who have an acute pelvic trauma with buttock swelling and excessive pain of the gluteal region. Any delay in diagnosis or treatment can be devastating, causing permanent disability, irreversible loss of gluteal muscles, sciatic nerve palsy, kidney failure, or even death.

  15. Penile Rehabilitation after Pelvic Cancer Surgery

    Directory of Open Access Journals (Sweden)

    Fouad Aoun


    Full Text Available Erectile dysfunction is the most common complication after pelvic radical surgery. Rehabilitation programs are increasingly being used in clinical practice but there is no high level of evidence supporting its efficacy. The principle of early penile rehabilitation stems from animal studies showing early histological and molecular changes associated with penile corporal hypoxia after cavernous nerve injury. The concept of early penile rehabilitation was developed in late nineties with a subsequent number of clinical studies supporting early pharmacologic penile rehabilitation. These studies included all available phosphodiesterase type 5 inhibitors, intracavernosal injection and intraurethral use of prostaglandin E1 and to lesser extent vacuum erectile devices. However, these studies are of small number, difficult to interpret, and often with no control group. Furthermore, no studies have proven an in vivo derangement of endothelial or smooth muscle cell metabolism secondary to a prolonged flaccid state. The purpose of the present report is a synthetic overview of the literature in order to analyze the concept and the rationale of rehabilitation program of erectile dysfunction following radical pelvic surgery and the evidence of such programs in clinical practice. Emphasis will be placed on penile rehabilitation programs after radical cystoprostatectomy, radical prostatectomy, and rectal cancer treatment. Future perspectives are also analyzed.

    To evaluate safe access route and success rate of percutaneous drainage of pelvic fluid collection. The 35 percutaneous drainages of pelvic fluid collection under the CT and fluorosocpic guidance were done in 32 patients. The anterior transabdominal approach was done in 20 patients, while the nine patients used the transgluteal approach through greater sciatic foramen. Three patients, who had septated or noncommunicating abscesses, underwent drainage using both approaches. The catheter was removed when the patient's symptom and laboratory data were improved or the amount of drainage and the size of fluid collection were markedly reduced. Success, partial success and failure were classified. The causes of fluid collection were complication of intraabdominal operation in 27 patient. The diagnosis after drainage included abscess (21), loculated ascites (6), and hematoma (4). The 27 cases (30 procedure) were treated successfully and the mean duration of catheter insertion was 10 days. The partial successes were two cases (2 procedures), which had palliative purpose. Three cases (3 procedures) were failed, which were multiple loculated ascites of pancreatic origin (2) and recurrent abscess (1). The significant complication during the procedure or drainage was not noted.

    Born, H.; Schmidt, C.


    In a retrospective study we analyzed the results of 127 patients, who were examined not only by means of conventional radiography but also by means of computed tomography after a trauma of the pelvic. Our investigations were based upon such patients, to whom a definite diagnostic procedure of plain radiography had been performed. Therefore all polytraumatized patients were inapplicable. They were only examined by computed tomography because of other more important accompanying injuries of other body regions. We compared the results of 127 patients with pelvic trauma. The results of the CT were in accordance with the results of the plain radiography for 103 patients. The results of the CT concerning the availability and the localization of the fractures were basically coincident with the plain radiography for 22 patients, but the CT showed a higher degree of trauma and additional intraarticular fragments. Two isolated lesions of the sacroiliac joint could not be recognized by both methods. They could only be diagnosed by bone scintigraphy on the third day after trauma.

    Full Text Available ABSTRACT: Radiographs are an irreplaceable diagnostic tool, es pecially in dealing with dentofacial hard tissues. Guidelines like the ALARA require professionals to limit the number of radiographs prescribed to patient, thereby minimizing radiation dose. On the other hand, for prosthetic evaluation, a latest radiograph has the po tential to uncover new findings that can alter the treatment planning sequence or affect the outcome of the planned treatment. This review article discusses ten such radiographs. The s ignificant findings in each radiograph have been highlighted and treatment protocols tailored t o the same. The aim of this article is to help the reader adopt a meticulous approach and a keen eye for detecting problems, and emphasizes the efficacy of radiographs in patient evaluation for restorative care

    Objective.To demonstrate the radiologic and pathologic manifestations of osteoid osteoma arising beneath the periosteum, on the surface of the bone. Design. One hundred and sixty osteoid osteomas were seen over a 30-year period. The radiologic, pathologic and operative findings of those that were subperiosteal were reviewed. Patients. Eleven patients with subperiosteal osteoid osteoma were reviewed. The patients ranged in age from 13 to 36 years with a mean of 24 years. Eight were male and three were female. Results and conclusion. Eleven subperiosteal lesions were studied. The reactive periostitis of four lesions was atypical and misleading. Four lesions had features similar to the more common intracortical variety. Three lesions occurring within the joint like other intra-articular lesions were barely seen on plain radiographs. Bone scan and CT scan were virtually diagnostic. The histopathology of these lesions was also atypical though not misleading. In conclusion, subperiosteal osteoid osteoma is a rare lesion with atypical radiographic and histopathologic features. The unusual reactive periostitis seen in several extra-articular cases may suggest other diagnoses. (orig.). With 4 figs., 2 tabs.

  2. Radiographic Evaluation of the Ankle Mortise

    Directory of Open Access Journals (Sweden)

    Hamid Mirbagheri


    Full Text Available The ankle joint is the most frequently injured joint in adults. Decisions on management are usually based on clinical examination and interpretation of the x-rays. Stability of the ankle mortise relies on the configuration of the osseous structures and the ligaments. A basic radiographic examination consists of a mortise-view and a lateral view. Some add the AP-view. The Mortise view is an AP-view with 15-25 degrees endorotation of the foot. "nThe view clearly demonstrates both lateral and medial joint spaces. On a true AP-view the talus overlaps a portion of the lateral malleolus obscuring the lateral aspect of the ankle joint. However, the AP-view will give you an extra view on both malleoli from a different angle. The lateral radiograph of the ankle should include the base of the fifth metatarsal because of the frequency of fractures at this side that clinically mimic a fracture of the ankle.

    Kim, Jin Soo; Kim, Young Jin; Choi, Eui Hwan; Kim, Jae Duk [Chosun University, Kwangju (Korea, Republic of)


    Condylar hyperplasia is a self-limiting condition characterized by a slowly progressing, enlargement of the mandible that results in facial asymmetry and a cross bite maloccusion. The facial asymmetry, open bite or cross bite, and radio graphic evidence of an enlarged condyle confirm the diagnosis of condylar hyperplasia. The etiology of the condition is unknown. This condition usually first becomes apparent during the second decade of life, when one condyle continues to grow while the other is no longer active. Radiographically, the condyle may appear enlarged or the neck of the condyle may be elongated or both may occur, sometimes, however, no raiographically demonstrable condylar abnormality will be noted. Surgical correction with subcondylar osteotomy is the treatment choice. We have observed two cases of condylar hyperplsia occurred in the left mandibular condyle of 24-year-old and 35-year- old women. We obtained that two cases were shown the followed results; 1. Clinically, both cases was unilaterally developed on C/C area, with temporomandibular disorders and pain, facial asymmetry and malcclusion. 2. Radiographically, hyperplastic mass confined to the condyle. 3. Histopathologically, these cases shown increased hypertrophic region in parts, and lamellated bone wit h irregular trabeculae.

  4. Susuk - black magic exposed "white" by dental radiographs. (United States)

    F, Arishiya Thapasum; Mohammed, Faraz


    Susuk or charm needles are a facial cum body art widely practiced among women of Malaysia, Brunei, Singapore, Thailand and Indonesia. These are small, needle-shaped metallic talismans inserted subcutaneously in different parts of the body. The concealed art of susuk was "exposed" by routine radiographic examination in the oral and maxillofacial region. This paper reports two such cases of unusual incidental radiographic finding in dental radiographs which were taken on a routine basis as part of the diagnostic work up. This article will also primarily enlighten the importance of radiographs in detecting such charm needles as the wearer keeps the body art a "hidden secret" thereby avoiding misdiagnosis.

  5. Computer Analysis Of ILO Standard Chest Radiographs Of Pneumoconiosis (United States)

    Li, C. C.; Shu, David B. C.; Tai, H. T.; Hou, W.; Kunkle, G. A.; Wang, Y.; Hoy, R. J.


    This paper presents study of computer analysis of the 1980 ILO standard chest radiographs of pneumoconiosis. Algorithms developed for detection of individual small rounded and irregular opacities have been experimented and evaluated on these standard radiographs. The density, shape, and size distribution of the detected objects in the lung field, in spite of false positives, can be used as indicators for the beginning of pneumoconiosis. This approach is potentially useful in computer-assisted screening and early detection process where the annual chest radiograph of each worker is compared with his (her) own normal radiograph obtained previously.

Copper sulfate reducing agent is very good solution for improving diagnostic quality of very dark radiograph and prevent reexposure of the patient.

  7. Modified axillary radiograph of the shoulder: a new position. (United States)

    Senna, Luís Filipe; Pires E Albuquerque, Rodrigo


    Obtaining axillary radiographs of the shoulder in acute trauma is not always feasible. The authors present a new modification of this radiographic view, in order to assess the anatomic relationship between the humeral head and the glenoid cavity. The incidence is performed with the patient sitting on X-ray table, with the affected limb supported thereon. The authors describe the case of a 28-year-old male who suffered an anterior glenohumeral dislocation that was clearly evidenced by this modified radiograph. The concentric relationship between the humeral head and the glenoid cavity was also easily confirmed by obtaining such radiograph after the reduction maneuver.

  8. A protocol for classifying normal- and flat-arched foot posture for research studies using clinical and radiographic measurements

    Menz Hylton B


    Full Text Available Abstract Background There are several clinical and radiological methods available to classify foot posture in research, however there is no clear strategy for selecting the most appropriate measurements. Therefore, the aim of this study was to develop a foot screening protocol to distinguish between participants with normal- and flat-arched feet who would then subsequently be recruited into a series of laboratory-based gait studies. Methods The foot posture of ninety-one asymptomatic young adults was assessed using two clinical measurements (normalised navicular height and arch index and four radiological measurements taken from antero-posterior and lateral x-rays (talus-second metatarsal angle, talo-navicular coverage angle, calcaneal inclination angle and calcaneal-first metatarsal angle. Normative foot posture values were taken from the literature and used to recruit participants with normal-arched feet. Data from these participants were subsequently used to define the boundary between normal- and flat-arched feet. This information was then used to recruit participants with flat-arched feet. The relationship between the clinical and radiographic measures of foot posture was also explored. Results Thirty-two participants were recruited to the normal-arched study, 31 qualified for the flat-arched study and 28 participants were classified as having neither normal- or flat-arched feet and were not suitable for either study. The values obtained from the two clinical and four radiological measurements established two clearly defined foot posture groups. Correlations among clinical and radiological measures were significant (p r = 0.24 to 0.70. Interestingly, the clinical measures were more strongly associated with the radiographic angles obtained from the lateral view. Conclusion This foot screening protocol provides a coherent strategy for researchers planning to recruit participants with normal- and flat-arched feet. However, further research is

  9. Introduction of an alternative standardized radiographic measurement method to evaluate volar angulation in subcapital fractures of the 5th metacarpal

    The purpose of the present study was to compare the intra- and interobserver reliability of two different measurement methods for volar angulation of the 5th metacarpal (MC) in an attempt to establish a new standard measurement method to reduce interobserver discrepancies for therapeutic decisions. Twenty patients with subcapital fractures of the 5th MC were radiologically investigated. Imaging consisted of a radiographs in antero-posterior and precise lateral view in addition to a CT scan of the 5th MC. Measurement of volar angulation was accomplished using the conventional and the shaft articular surface (SAS) method. The measurements of five investigators were exported to a spreadsheet for statistical analysis to evaluate the intra-and interobserver reliability. The conventional technique showed large differences among the investigators and poor interobserver reliability (W = 0.328 and 0.307) both at injury (p = 0.001) and at follow-up (p = 0.189). The intraobserver concordance of all investigators showed better results with the SAS than with the conventional technique. With the SAS technique, no statistically significant difference among the investigators could be detected at either the time of injury (p = 0.418) or at follow-up (p = 0.526) with excellent interobserver reliability (W = 0.051 and W = 0.041). Evaluation of volar angulation at follow-up using CT scans did not show any statistically significant difference between the techniques with better correlation among the observers with the SAS technique (p = 0.838). The interobserver correlation of volar angulation with lateral radiographs using the conventional technique was insufficient. Therefore, we recommend the use of the novel SAS technique as standardized measurement method which showed higher accuracy and interobserver reliability in order to facilitate the choice of adequate treatment option.

  10. [The place of pelvic adhesions in gynecology. Possibilities of prevention]. (United States)

    Inovay, J; Szendei, G


    The authors review the recent international literature dealing with the role of pelvic adhesions in gynaecologic surgery. They point out that pelvic adhesions can be detected via laparatomy or laparoscopy in every third patient suffering from chronic pelvic pain, whereas abdominal adhesions revealed rarely correlate with anamnestic chronic pelvic pain. Correlation of pelvic pain and adhesions is neither consequent nor mutual. Lacking more detailed information on the pathomechanism of pain, the role of the vegetative innervation of the visceral and parietal peritoneum and of the excitation of the nerve fibers in the neoformed-and vascularized adhesions can only be postulated. According to the attractive but not well established theory extensive adhesions can directly provoke pain through fixing the pelvic organs hampering their motility and mobility. It is generally accepted, that lysis of adhesions in symptomatic patients can resolve or reduce the complaints. However the duration of the beneficial effect and its transitoric or definitive nature cannot be predicted in advance. Subsequently the authors review the adjuvant methods complementary to microsurgical techniques possibly preventing the formation and neoformation of pelvic adhesions. Despite of general acceptance and widespread usage, the effectiveness of crystalloids, macromolecular solutions, intraperitoneal heparin and steroids in the prevention of adhesions cannot be scientifically supported. The encouraging results already achieved by mechanical barriers (intercede, Gore-Tex) can hopefully be surpassed by biodegradable barriers actually studied in animal models.

  11. Knowledge of the pelvic floor in nulliparous women. (United States)

    Neels, Hedwig; Wyndaele, Jean-Jacques; Tjalma, Wiebren A A; De Wachter, Stefan; Wyndaele, Michel; Vermandel, Alexandra


    [Purpose] Proper pelvic floor function is important to avoid serious dysfunctions including incontinence, prolapse, and sexual problems. The current study evaluated the knowledge of young nulliparous women about their pelvic floor and identified what additional information they wanted. [Subjects and Methods] In this cross-sectional survey, a validated, 36 item questionnaire was distributed to 212 nulliparous women. The questionnaire addressed demography, pelvic floor muscles, pelvic floor dysfunction, and possible information sources. Descriptive statistics were generated for all variables. Stability and validity testing were performed using Kappa statistics and intra class correlation coefficients to define agreement for each question. The study was approved by the ethics Committee (B300201318334). [Results] Using a VAS scale (0 to 10), the women rated their knowledge about the pelvic floor as a mean of 2.4 (SD 2.01). A total of 93% of the women were insufficiently informed and requested more information; 25% had concerns about developing urinary incontinence, and 14% about fecal incontinence. Many of the women were unaware what pelvic floor training meant. [Conclusion] There was a significant lack of knowledge about pelvic floor function among nulliparous women. The majority of nulliparous women expressed a need for education, which might offer a way to reduce dysfunction.

    Young, Amy E; Fine, Paul M; McCrery, Rebecca; Wren, Patricia A; Richter, Holly E; Brubaker, Linda; Brown, Morton B; Weber, Anne M


    The purpose of the study is to translate existing measures of pelvic symptoms and quality of life from English into Spanish, facilitating research participation of Hispanic/Latina women. The forward-backward translation protocol was applied then adjudicated by a concordance committee. The measures included the Pelvic Floor Distress Inventory (PFDI), Pelvic Floor Impact Questionnaire (PFIQ), Medical, Epidemiological, and Social Aspects of Aging (MESA) Questionnaire, Hunskaar Severity Measure, Fecal Incontinence Severity Index and modified Manchester Questionnaire, Pelvic Organ Prolapse/Urinary Incontinence Sexual Functioning Questionnaire (PISQ), and the Life Orientation Test (LOT). English and Spanish versions were administered to 50 Hispanic/Latina women with pelvic symptoms. Kappa correlations of items and correlation coefficients for scales were computed. Psychometric testing for translations demonstrated good (0.80-0.89), very good (0.90-0.95), or excellent (>0.95) correlations for primary scales of the PFDI, PFIQ, MESA, Hunskaar, PISQ, and LOT. Strict translation techniques and testing yielded valid Spanish translations of instruments assessing pelvic symptoms/functional life impact in women with pelvic floor disorders.

    Full Text Available Introduction: Chronic pelvic pain (CPP is a common medical problem affecting women. Too often the physical signs are not specific. This study aims at determining the accuracy of diagnostic laparoscopy over clinical pelvic examination. Settings and Design: A retrospective study of patients who underwent diagnostic laparoscopy for CPP. Materials and Methods: The medical records of 86 women who underwent laparoscopic evaluation for CPP of at least 6-month duration were reviewed for presentation of symptoms, pelvic examination findings at the admission, operative findings and follow up when available. Statistical analysis used: McNemar Chi-square test for frequencies in a 2 x 2 table. Results: The most common presentation was acyclic lower abdominal pain (79.1%, followed by congestive dysmenorrhoea (26.7%. 61.6% of women did not reveal any significant signs on pelvic examination. Pelvic tenderness was elicited in 27.9%. Diagnostic laparoscopy revealed significant pelvic pathology in 58% of those who essentially had normal pervaginal findings. The most common pelvic pathology by laparoscopy was pelvic adhesions (20.9%, followed by pelvic congestion (18.6%. Laparoscopic adhesiolyis achieved pain relief only in one-third of the women. Conclusion: The study revealed very low incidence of endometriosis (4.7%. Overall clinical examination could detect abnormality in only 38% of women, where as laparoscopy could detect significant pathology in 66% of women with CPP. This shows superiority of diagnostic laparoscopy over clinical examination in detection of aetiology in women with CPP (P < 0.001. Adhesiolysis helps only small proportion of women in achieving pain control.

  14. Finding the neck-trunk boundary in snakes: anteroposterior dissociation of myological characteristics in snakes and its implications for their neck and trunk body regionalization. (United States)

    Tsuihiji, Takanobu; Kearney, Maureen; Rieppel, Olivier


    The neck and trunk regionalization of the presacral musculoskeletal system in snakes and other limb-reduced squamates was assessed based on observations on craniovertebral and body wall muscles. It was confirmed that myological features characterizing the neck in quadrupedal squamates (i.e., squamates with well-developed limbs) are retained in all examined snakes, contradicting the complete lack of the neck in snakes hypothesized in previous studies. However, the posterior-most origins of the craniovertebral muscles and the anterior-most bony attachments of the body wall muscles that are located at around the neck-trunk boundary in quadrupedal squamates were found to be dissociated anteroposteriorly in snakes. Together with results of a recent study that the anterior expression boundaries of Hox genes coinciding with the neck-trunk boundary in quadrupedal amniotes were dissociated anteroposteriorly in a colubrid snake, these observations support the hypothesis that structures usually associated with the neck-trunk boundary in quadrupedal squamates are displaced relative to one another in snakes. Whereas certain craniovertebral muscles are elongated in some snakes, results of optimization on an ophidian cladogram show that the most recent common ancestor of extant snakes would have had the longest craniovertebral muscle, M. rectus capitis anterior, that is elongated only by several segments compared with that of quadrupedal squamates. Therefore, even such a posteriorly displaced "cervical" characteristic plesiomorphically lies fairly anteriorly in the greatly elongated precloacal region of snakes, suggesting that the trunk, not the neck, would have contributed most to the elongation of the snake precloacal region. A similar dissociation of structures usually associated with the neck-trunk boundary in quadrupedal squamates is observed in limb-reduced squamates, suggesting that these forms and snakes may share a developmental mechanism producing modifications in the

  16. Proximal femoral canal shape is more accurately assessed on AP hip radiographs than AP pelvis radiographs in primary hip osteoarthritis. (United States)

    Merle, Christian; Waldstein, Wenzel; Gregory, Jennifer S; Goodyear, Simon R; Aspden, Richard M; Aldinger, Peter R; Murray, David W; Gill, Harinderjit S


    The objectives of the present study were to determine whether differences in the radiographic appearance of the of the proximal femoral canal exist on corresponding AP pelvis and AP hip radiographs, and whether radiographic assessment of canal shape is accurate with reference to computed tomography (CT). In a retrospective study, corresponding radiographs and CT scans of 100 consecutive patients with primary hip OA were evaluated. Active shape modelling (ASM) was performed to assess the variation in proximal femoral canal shape and to identify differences between AP hip and AP pelvis views. Differences in the medial cortical flare between radiographs and CT were quantified using least squares curve fitting. ASM identified significant differences in the assessment of canal shape on corresponding AP hip and AP pelvis views. Curve fitting demonstrated a good agreement between AP hip radiographs and CT. Agreement between AP pelvis radiographs and CT was less good. In contrast to AP pelvis radiographs, AP hip radiographs allow a more accurate and reliable assessment of proximal femoral canal shape in the frontal plane in primary hip OA. Our findings may improve stem fit in total hip arthroplasty without the routine use of CT.

  17. Pelvic Organ Prolapse Quantification System (POP-Q) - a new era in pelvic prolapse staging. (United States)

    Persu, C; Chapple, C R; Cauni, V; Gutue, S; Geavlete, P


    The prolapse of one or several pelvic organs is a condition that has been known by medicine since its early days, and different therapeutic approaches have been proposed and accepted. But one of the main problems concerning the prolapse of pelvic organs is the need for a universal, clear and reliable staging method.Because the prolapse has been known and recognized as a disease for more than one hundred years, so are different systems proposed for its staging. But none has proved itself to respond to all the requirements of the medical community, so the vast majority were seen coming and going, failing to become the single most useful system for staging in pelvic organ prolapse (POP).The latest addition to the group of staging systems is the POP-Q system, which is becoming increasingly popular with specialists all over the world, because, although is not very simple as a concept, it helps defining the features of a prolapse at a level of completeness not reached by any other system to date. In this vision, the POP-Q system may reach the importance and recognition of the TNM system use in oncology.This paper briefly describes the POP-Q system, by comparison with other staging systems, analyzing its main features and the concept behind it.

  18. Risk of pelvic injury from femoral neck guidewires. (United States)

    Feeney, M; Masterson, E; Keogh, P; Quinlan, W


    Many of the devices used in the internal fixation of femoral neck fractures are cannulated and require the initial placement of one or more guidewires for accurate positioning. These wires are occasionally advanced inadvertently through the hip joint and the acetabulum. Pelvic visceral damage may follow. To assess this risk, we inserted three guidewires to a depth of 16 cm into each femoral neck of ten cadavers and explored the pelvis during autopsy. Thirty-two of the 60 guidewires had penetrated a pelvic organ. The literature on intrapelvic injuries associated with hip surgery is reviewed, and suggestions are offered on the avoidance of pelvic penetration during hip fracture fixation.

    Full Text Available Background/Objective: Ultrasonography has replaced roentgenography in recent obstetric practice. X-ray pelvimetry in the management of vaginal delivery in patients with previous cesarean section is the only exception in some centers. There has been no report of the prevalence of four major pelvic types in Iranian females before this study."nPatients and Methods: In this study, we evaluated the types of pelvis and pelvic measurements of 185 adult female patients in four different regional municipalities of Mashhad. AP pelvic x-ray was performed for all the patients. All images were reported by a radiologist."nResults: Gynecoid pelvis was the most common pelvic type (88.6% followed by platyploid (7.6%, android (2.7% and anthropoid (1.1%. The results including the types of pelvis and the measurements had significant differences with previous studies in western countries. There were no significant differences in the prevalence of pelvic types between different imaging centers, different age groups and nulliparous vs. parous patients. "nConclusion: The prevalence of pelvic types depends on human race but it does not appear to be influenced by parity or age.

  20. [Reconstructive surgery of female pelvic floor prolapse]. (United States)

    Schär, Gabriel


    It is recommended to perform pelvic floor prolapse surgery within a concept which bases on the women's symptoms, the expectations on life quality and functional aspects of the vagina, urinary bladder and rectum. Decisions on type of surgery must also be founded on the anatomical defect. An apical prolapse should either be fixed by sacrospinous ligament suspension or by sacrocolpopexy. In case of a cystocele the type of defect must be considered; a cystocele with a central defect can be corrected by anterior colporrhaphy whereas the cystocele caused by a paravaginal defect needs lateral fixation which today is increasingly done by vaginal mesh surgery. Rectocele repair is performed by posterior colporrhaphy. Knowledge of success and complication rates is essential for taking the right surgical decisions and for counselling the patient.

  1. Pelvic radiation therapy: Between delight and disaster

    Institute of Scientific and Technical Information of China (English)

    Kirsten; AL; Morris; Najib; Y; Haboubi


    In the last few decades radiotherapy was established as one of the best and most widely used treatmentmodalities for certain tumours. Unfortunately that came with a price. As more people with cancer survive longer an ever increasing number of patients are living with the complications of radiotherapy and have become, in certain cases, difficult to manage. Pelvic radiation disease(PRD) can result from ionising radiationinduced damage to surrounding non-cancerous tissues resulting in disruption of normal physiological functions and symptoms such as diarrhoea, tenesmus, incontinence and rectal bleeding. The burden of PRDrelated symptoms, which impact on a patient’s quality of life, has been under appreciated and sub-optimally managed. This article serves to promote awareness of PRD and the vast potential there is to improve current service provision and research activities.

  2. Sciatica due to pelvic hematoma: case report

    Directory of Open Access Journals (Sweden)

    Kocaman Umit


    Full Text Available Sciatica is defined as pain in the sciatic nerve distribution. The most common reason of sciatica is radiculopathy due to lumbar disc hernia. Other causes can be congenital, acquired, infectious, neoplastic, or inflammatory. The piriformis syndrome is another cause. The pain starts in an insidious manner when the cause of sciatica is an extraspinal tumor. It is intermittent at first but a constant and progressive pain that does not decrease with position or rest gradually develops in all patients. The possibility of an intraabdominal or pelvic mass should always be considered and the relevant tests requested when the cause of the sciatica cannot be explained. We present an 83-year-old male who presented with non-traumatic and non-vascular lumbosacral plexopathy due to a large hematoma in the left adductor muscle following the use of warfarin sodium.

  3. [Lithiasis and ectopic pelvic kidney. Therapeutic aspects]. (United States)

    Aboutaieb, R; Rabii, R; el Moussaoui, A; Joual, A; Sarf, I; el Mrini, M; Benjelloun, S


    Kidney in ectopic position is dysplasic, and associated to other malformations. The advent of a lithiasis in these conditions rises questions about therapeutic options. We report on five observations of pelvic ectopic kidney with urinary lithiasis. Patients were aged from 16 to 42 years. Kidney was non functional in two cases, or with normal appearance sized 10 to 12 cm. We performed total nephrectomy in two cases, pyelolithotomy in the other cases. Surgical approach was subperitoneal via iliac route. A dismembered pyeloplasty was associated in one case. All patients did well. Radiologic control at 6 and 12 months showed no recurrence in a well functioning kidney. Surgical lithotomy is advocated as a treatment in urinary lithiasis affecting ectopic kidney. It is an easy procedure which permits correction of other associated malformations.

  4. Pelvic alveolar rhabdomyosarcoma in a young adult

    Directory of Open Access Journals (Sweden)

    David Reisner, MD


    Full Text Available Rhabdomyosarcomas are soft-tissue tumors, rare in adults. Accounting for nearly 5% of childhood cancers, they represent less than 0.03% of adult malignancies (1, 2. Three different subtypes of rhabdomyosarcoma have been described (embryonal, alveolar and pleomorphic, making up approximately 50%, 30%, and 20% of the cases, respectively (3. Although the definitive diagnosis is made pathologically, some distinguishing features among these subtypes, and between rhabdomyosarcomas and other soft-tissue tumors, can be suggested on MRI and CT. We present an interesting case of a 20-year-old female with a locally aggressive pelvic alveolar rhabdomyosarcoma. While the prognosis has improved with newer treatment techniques, overall survival rates remain poor. Our case study presents typical features of a rare disease, which can often present a diagnostic dilemma for clinicians.

  5. Chlamydia trachomatis in pelvic inflammatory disease. (United States)

    Shrikhande, S N; Joshi, S G; Zodpey, S P; Saoji, A M


    The prevalence of genital Chlamydia trachomatis infection and some epidemiologic factors associated with it were studied in 273 pelvic inflammatory disease (PID) patients attending Gynaecologic clinic, Government Medical College, Nagpur. For detection of chlamydial antigen Pharmacia Diagnostics Chlamydia EIA test was used. This study revealed an overall positivity rate of 33% for C. trachomatis infection in PID patients. Of the hypothesised risk factors low socioeconomic status, history of sexual contacts with multiple partners and use of intrauterine devices (IUD) were significantly associated with C. trachomatis infections. However, use of oral contraceptives, barrier contraceptives and increasing age were found to be protective factors for C. trachomatis infection. Thus considering the significant contribution of C. trachomatis in etiology of PID and its independent association with some epidemiologic risk factors, extensive epidemiologic measures are recommended for prevention of these infections.

    Treviño Salinas, Emilio Modesto; Martínez Palones, José María; Pérez Benavente, Ma Asunción; Xercavins Montosa, Jordi


    Pelvic actinomycosis is a granulomatous chronic illness due to anaerobic, gram-positive, branching filamentous bacteria (Actinomyces israelii), this and other species of actinomyces occur in the normal flora of the gastrointestinal and genital tract in humans. Infection is associated in women using an IUD (Intrauterine device) for long periods and it has the characteristic of simulate malignant diseases causing most of the times wrong preoperative diagnosis. We analyzed a postmenopausal patient who was treated surgically without specific diagnosis, then by anatomo-pathologic study of the specimen the result was actinomycosis. The main purpose to obtain the correct preoperative diagnosis is because we have to use antibiotics in the treatment and it may reduce the frequency of radical surgeries.

  7. From interstitial cystitis to chronic pelvic pain. (United States)

    Persu, C; Cauni, V; Gutue, S; Blaj, Irina; Jinga, V; Geavlete, P


    There are still many things to be found out about interstitial cystitis/painful bladder syndrome (IC/PBS) because the pathological processes underlying the condition are not yet elucidated, biological markers of the condition are not yet available, and the type and severity of symptoms can vary, so, clearly defining the condition is not yet possible. For example, it is not clearly understood whether IC/PBS represents a systemic disease, if it is localized in the bladder, or if it was initially localized in the bladder and it later evolved into a systemic disease. This condition is best managed by using a multidisciplinary approach. Management requires a good integration and knowledge of all pelvic organ systems and other systems including musculoskeletal, neurologic, and psychiatric systems.

  8. Transverse plane pelvic rotation increase (TPPRI following rotationally corrective instrumentation of adolescent idiopathic scoliosis double curves

    Directory of Open Access Journals (Sweden)

    Asher Marc A


    Full Text Available Abstract Background We have occasionally observed clinically noticeable postoperative transverse plane pelvic rotation increase (TPPRI in the direction of direct thoracolumbar/lumbar rotational corrective load applied during posterior instrumentation and arthrodesis for double (Lenke 3 and 6 adolescent idiopathic scoliosis (AIS curves. Our purposes were to document this occurrence; identify its frequency, associated variables, and natural history; and determine its effect upon patient outcome. Methods Transverse plane pelvic rotation (TPPR can be quantified using the left/right hemipelvis width ratio as measured on standing posterior-anterior scoliosis radiographs. Descriptive statistics were done to determine means and standard deviations. Non-parametric statistical tests were used due to the small sample size and non-normally distributed data. Significance was set at P Results Seventeen of 21 (81% consecutive patients with double curves (7 with Lenke 3 curves and 10 with Lenke 6 instrumented with lumbar pedicle screw anchors to achieve direct rotation had a complete sequence of measurable radiographs. While 10 of these 17 had no postoperative TPPRI, 7 did all in the direction of the rotationally corrective thoracolumbar instrumentation load. Two preoperative variables were associated with postoperative TPPRI: more tilt of the vertebra below the lower instrumented vertebra (-23° ± 3.1° vs. -29° ± 4.6°, P = 0.014 and concurrent anterior thoracolumbar discectomy and arthrodesis (5 of 10 vs. 7 of 7, P = 0.044. Patients with a larger thoracolumbar/lumbar angle of trunk inclination or larger lower instrumented vertebra plus one to sacrum fractional/hemicurve were more likely to have received additional anterior thoracolumbar discectomy and arthrodesis (c = 0.90 and c = 0.833, respectively. Postoperative TPPRI resolved in 5 of the 7 by intermediate follow-up at 12 months. Patient outcome was not adversely affected by postoperative TPPRI

    Aim: To evaluate the efficacy of biofeedback therapy in patients with chronic pelvic pain syndrome(CPPS). Methods: From November 2001 to April 2002, patients visiting the Urological Outpatient Clinic of this Hospital were evaluated by means of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI)and classified by the NIH classification standard. Sixty-two patients of CPPS category Ⅲ were involved in this study. All patients had been treated by conventional approaches such as antibiotics and alpha-blockers for more than half a year without any improvement. The expressed prostatic secretion results were as follows: WBC 5 to 9/high power field, lipid +-+++ and bacterial culture negative. Their NIH-CPSI were 12-40. All the 62 cases complained of micturitional irritation (frequency, urgency, splitted stream and sense of residual urine), 32 cases, of pain or discomfort at the testicular, penile, scrotal, pelvic or rectal region and 13 cases, of white secretion-dripping. The patients were treated by the Urostym Biofeedback equipment (Laborie Co., Canada) 5 times a week for 2 weeks with a stimulus intensity of 15 mA-23 mA and duration of 20 minutes. Results: Sixty patients were significantly improved or cured, while no significant improvement in the remaining 2. No apparent side effect was observed. The NIH-CPSI dropped to 6 to 14 with an average reduction of 21 (P<0.01). In the 60 improved cases, pain was relieved after 2-3treatment courses and other symptoms disappeared after 4-5 courses. Conclusion: Biofeedback therapy is a safe and effective treatment for CPPS. Large randomized clinical trials are needed to confirm its efficacy and to explore the mechanism of action.

    Full Text Available Introduction: In the gynecological profession Pelvic Inflammatory Disease (PID has a significant role due to its frequency, many complications and high costs of treatment Aim: The aim of this study was to investigate frequency and complications caused by these diseases, and used methods of treatment. Methods: The research was conducted in Clinic of Obstetrics and Gynecology 'Narodni Front', Belgrade, and included all consecutive patients diagnosed with PID during the period from year 2007 to 2010. The diagnosis of PID was set on the basis of: gynecological examination, test analysis (leucocytes, sedimentation, platelets, CRP, CA125, and ultrasound examination. A clinical criterion is divided into minimal and additional. The study included 112 patients. There were 33.93% of women in perimenopause/menopause (experimental group, while the control group consisted of 66.07% female subjects. Results: The frequency of surgically treated patients in experimental and control group was: 44.74% : 39.19% (χ2 test; p > 0.05. Women in experimental group used Intrauterine Device (IUD more than other patients 57.89% : 13.15% (χ2 test; p = 0.0001. A link was established between the use of intrauterine devicela in (χ2 test; p = 0.0516, patients’ irregular control of IUD (χ2 test; p = 0.0114 and surgical treatments of women in experimental group. The conservative treatment usually applies dual antibiotic therapy. Costs of surgically treated patients are around 1300 and conservatively treated around 210 €. Conclusion: Women in perimenopause and menopause are not exposed to higher risks of contracting PID. Women in perimenopause and menopause which use intrauterine device and don’t have regular controls, have higher risk of surgical treatments in case of pelvic inflammatory disease. Costs of treatment are 6-7 times in lower with conservatively treated patients compared to operatively treated ones.

    The female pelvic floor is an understudied region of the body from the biomechanical perspective. MRI has been used in the diagnostic evaluation of the pelvic floor dysfunctions. Static images show their morphology while dynamic images show the functional changes that occur on straining and contraction of the pelvic floor. In the present work, MR images contribute to generate 3D solids of pelvic floor muscles through manual segmentation. To study the biomechanical behavior of pelvic floor mus...

  12. Radiographer perceptions of managerial transformational leadership levels. (United States)

    Legg, Jeffrey S; Akroyd, Duane; Jackowski, Melissa B


    Transformational leadership focuses on the ability of a leader to impact employees by inspiring employees to broaden interests in work as well as to be innovative and creative. It is positively associated with employee satisfaction and commitment to the organization. Characteristics of transformational leaders include confidence, ability to mange and deal with complexity, and belief in their employees and organizations. Considering the importance of leadership skills in radiology departments, this paper addresses directly the empirical evidence concerning radiographer's perception of their radiology managers and supervisors transformational leadership levels in the United States. Leadership can be taught, and we as a profession must begin to implement leadership training programs for our current and future leaders.

  13. Radiographic studies of the ventricles in syringomyelia

    Energy Technology Data Exchange (ETDEWEB)

    West, R.J.; Williams, B.


    Radiographic investigations of 171 patients with communicating syringomyelia have been reviewed. Hydrocephalus was found in one third of the cases and has occasionally progressed after operation on the posterior fossa, sometimes with accompanying clinical deterioration. The outlets of the fourth ventricle were usually abnormal; tonsillar descent, arachnoiditis and both together were seen. Arachnoiditis correlated strongly with a history of difficult birth. The foramen of Magendie was sometimes patent and sometimes blocked. There was no consistent level of occlusion corresponding to a persistent roof of the fourth ventricle. The cisterna magna was usually small or obliterated but some examples of large cisterns or subarachnoid pouches were found. Radiological demonstration of a communication from the fourth ventricle to the syrinx occurred in only seven patients by positive contrast material and not by air. It is suggested that a sizable communication is rare at the time when patients seek treatment.

    Singh Anil


    Full Text Available Spinal cord injury without radiological abnormality is rare in adults. Below we present a case report of 20 yrs old male with isolated cervical cord injury, without accompanying vertebral dislocation or fracture involving the spinal canal rim. He fell down on plain and smooth ground while carrying 40 kg weight overhead and developed quadriparesis with difficulty in respiration. Plain radiographs of the neck revealed no fractures or dislocations. MRI showed bulky spinal cord and an abnormal hyper intense signal on the T2W image from C2 vertebral body level to C3/4 intervertebral disc level predominantly in the anterior aspect of the cord The patient was managed conservatively with head halter traction and invasive ventilatory support for the initial 7 days period in the ICU. In our patient recovery was good and most of the neurological deficit improved over 4 weeks with conservative management.

  15. Iterative Reconstruction of Coded Source Neutron Radiographs

    Energy Technology Data Exchange (ETDEWEB)

    Santos-Villalobos, Hector J [ORNL; Bingham, Philip R [ORNL; Gregor, Jens [University of Tennessee, Knoxville (UTK)


    Use of a coded source facilitates high-resolution neutron imaging through magnifications but requires that the radiographic data be deconvolved. A comparison of direct deconvolution with two different iterative algorithms has been performed. One iterative algorithm is based on a maximum likelihood estimation (MLE)-like framework and the second is based on a geometric model of the neutron beam within a least squares formulation of the inverse imaging problem. Simulated data for both uniform and Gaussian shaped source distributions was used for testing to understand the impact of non-uniformities present in neutron beam distributions on the reconstructed images. Results indicate that the model based reconstruction method will match resolution and improve on contrast over convolution methods in the presence of non-uniform sources. Additionally, the model based iterative algorithm provides direct calculation of quantitative transmission values while the convolution based methods must be normalized base on known values.

    We experienced 3 cases of intrahepatic duct stones detected on plain radiographs. The patients had history of multiple episodes of recurrent cholangitis. Radiographic characteristics of these stones included multiple, round or rectangular radiopaque densities surrounded by calcified rim; these densities showed a branching pattern along the intrahepatic ducts.

  19. Comparative analysis of human and bovine teeth: radiographic density

    Directory of Open Access Journals (Sweden)

    Jefferson Luis Oshiro Tanaka


    Full Text Available Since bovine teeth have been used as substitutes for human teeth in in vitro dental studies, the aim of this study was to compare the radiographic density of bovine teeth with that of human teeth to evaluate their usability for radiographic studies. Thirty bovine and twenty human teeth were cut transversally in 1 millimeter-thick slices. The slices were X-rayed using a digital radiographic system and an intraoral X-ray machine at 65 kVp and 7 mA. The exposure time (0.08 s and the target-sensor distance (40 cm were standardized for all the radiographs. The radiographic densities of the enamel, coronal dentin and radicular dentin of each slice were obtained separately using the "histogram" tool of Adobe Photoshop 7.0 software. The mean radiographic densities of the enamel, coronal dentin and radicular dentin were calculated by the arithmetic mean of the slices of each tooth. One-way ANOVA demonstrated statistically significant differences for the densities of bovine and human enamel (p 0.05. Based on the results, the authors concluded that: a the radiographic density of bovine enamel is significantly higher than that of human enamel; b the radiodensity of bovine coronal dentin is statistically lower than the radiodensity of human coronal dentin; bovine radicular dentin is also less radiodense than human radicular dentin, although this difference was not statistically significant; c bovine teeth should be used with care in radiographic in vitro studies.

E-mail:; Robertson, Elizabeth M. [Department of Radiology, Aberdeen Royal Infirmary, Foresterhill, Aberdeen AB25 2ZN (United Kingdom)]. E-mail:


    Aim: To survey the perceptions of the Scottish radiology community in relation to radiographer role development. Methods: A postal questionnaire was sent to all consultant radiologists recorded on the NHS Scotland database of consultants. Results: Response rate was 63%. (i) Respondents considered increased professional standing of radiographers, best use of manpower resources, reduced pressure on the service and improved recruitment and retention, as positive advantages of radiographer development. (ii) The potential impact on radiology specialist registrar training, lack of clear medico-legal responsibilities and radiographers recognising the limitations of their abilities were identified as the main areas of radiologist anxiety. (iii) Fifty-seven percent did not consider current post-registration radiography education and training resources adequate to underpin the requirement of developed roles. (iv) Barriers to radiographer development were identified as lack of radiography and radiology staff, suitable education, financial constraints, traditional views and resistance to change. (v) Eighty-two percent reported support for radiographer role development and willingness to participate actively in developments. Conclusion: Despite reservations Scottish radiologists are supportive of the development of radiography colleagues, however, guidance is required on the medico-legal and accountability aspects of radiographers assuming new roles. Radiologist involvement in education and training for new roles may increase their confidence and trust in radiographers to work within the limitations of their competency and training.

    In this study, clinical and radiological results were evaluated in patients with Legg-Calve-Perthes disease treated with Salter pelvic osteotomy. Between 2004 and 2008, 16 patients underwent a Salter osteotomy as treatment for Legg-Calve-Perthes disease (15 male, 1 female; 10 right hip, 6 left hip). The mean age at the time of surgery was 8.1 +/- 1.4 (range: 6 to 10) years. Surgical indications were : age between 6-10 years at the onset of the disease; Herring classification type B, B/C, or C; and at least one risk sign. 6-8 year old patients were classified as group I and 9-10 year olds were classified as group II. We investigated the effects of age and Herring classification on radiological outcomes. The final radiographic evaluation according to the Stulberg classification showed nine hips (56.25%) classified as good (Stulberg I/II), five (31.25%) as fair (Stulberg III); and two (12.5%) as poor (Stulberg IV). In group I, 7 patients (70%) had good results, while only 2 (33.3%) in group II. The results in group I were statistically better than group II (p Salter pelvic osteotomy is an effective method of surgical treatment for Legg-Cave-Perthes in patients between 6-8 years of age.

    Giuseppe La Pera


    Full Text Available Objectives: To assess the cure rate of patients with premature ejaculation who underwent a treatment involving: 1 awareness of the pelvic floor muscles 2 learning the timing of execution and maintenance of contraction of the pelvic floor muscles during the sensation of the pre-orgasmic phase 3 pelvic floor rehabilitation (bio feed back, pelvic exercises and electrostimulation. Materials and methods: We recruited 78 patients with lifelong premature ejaculation who completed the training. The patients were informed of the role of the pelvic floor. They were taught to carry out the execution and maintenance of contraction of the pelvic floor muscles during the sensation of the pre-orgasmic phase to control the ejaculatory reflex. In order to improve the awareness, the tone and the endurance of the pelvic floor muscles, patients were treated with the rehabilitation of pelvic floor (RPF consisting mainly in biofeedback, pelvic exercises and in some cases also in electro-stimulation (ES. The training was carried out for a period of about 2-6 months with an average of 2-5 visits per cycle. Results: 54% of patients who completed the training were cured of premature ejaculation and learned over time to be able to postpone the ejaculation reflex. In a subgroup of 26 patients was also measured the IELT which on the average increased from < 2 minutes to >10 minutes. The best results occurred mainly in patients aged less than 35 where the cure rate was 65%. There were no side effects. Conclusions: In this study, approximately half of patients with premature ejaculation were cured after applying the above treatment.This therapy, necessitates a fairly long period of time (2-6 months and a great commitment on the part of the patient, nevertheless it can be a valid and effective treatment for patients with premature ejaculation. This treatment makes the patient independent in that he is not bound to specific times for taking medication. Furthermore there are no

  5. Inferring Morphology and Strength of Magnetic Fields From Proton Radiographs

    CERN Document Server

    Graziani, Carlo; Lamb, Donald Q; Li, Chikang


    Proton radiography is an important diagnostic method for laser plasma experiments, and is particularly important in the analysis of magnetized plasmas. The theory of radiographic image analysis has heretofore only permitted somewhat limited analysis of the radiographs of such plasmas. We furnish here a theory that remedies this deficiency. We show that to linear order in magnetic field gradients, proton radiographs are projection images of the MHD current along the proton trajectories. We demonstrate that in the linear approximation, the full structure of the perpedicular magnetic field can be reconstructed by solving a steady-state inhomogeneous 2-dimensional diffusion equation sourced by the radiograph fluence contrast data. We explore limitations of the inversion method due to Poisson noise, to discretization errors, to radiograph edge effects, and to obstruction by laser target structures. We also provide a separate analysis that is well-suited to the inference of isotropic-homogeneous magnetic turbulence...

    Kirkeby, Mette J; Biering, Karin; Olsen, Jørn


    AIM: Menarcheal age is a predictor of several complications related to pregnancy and diseases later in life. We aimed to study if menarcheal age is a risk factor for pregnancy-related pelvic pain. MATERIAL AND METHODS: A nested case-control study was conducted within the Danish National Birth...... Cohort, a cohort of pregnant women, recruited during 1996-2002, and their children. In the second trimester of pregnancy the women provided information about age at menarche and potential confounders. Selection of cases (n = 2227) was based on self-reported pelvic pain during pregnancy from an interview...... done 6 months post-partum. The controls (n = 2588) were randomly selected among women who did not report pelvic pain. We used logistic regression analysis to calculate odds ratios (OR) for pregnancy-related pelvic pain according to age at menarche. RESULTS: In the cohort, 18.5% of all pregnant women...

  9. Can Surgery Be Avoided? Exclusive Antibiotic Treatment for Pelvic Actinomycosis (United States)

    Williams, E. M.; Markey, C. M.; Johnson, A. M.; Morales-Ramirez, P. B.


    Pelvic actinomycosis is an uncommon, slowly progressing granulomatous infection that has been associated with the presence of intrauterine devices. Due to its unspecific clinical and radiologic findings, it can mimic pelvic or intra-abdominal malignancy leading to mutilating surgery of high morbidity. Rarely, diagnosis is made preoperatively and in most cases surgical intervention is necessary. The patient in our case is a 42-year-old female with an IUD for 15 years diagnosed with pelvic actinomycosis. Patient was uniquely diagnosed preoperatively through paracentesis and treated conservatively with prolonged antibiotic therapy and without any type of surgical intervention. Follow-up at 1 year showed almost complete radiologic resolution of the inflammatory mass, nutritional recovery, and absence of symptoms. Pelvic actinomycosis can be successfully diagnosed and treated medically without surgical interventions. PMID:28299218

  12. Can pelvic tilting be ignored in total hip arthroplasty?

    Directory of Open Access Journals (Sweden)

    Won Yong Shon


    CONCLUSION: The sagittal position of pelvis is a key factor in impingement and dislocation after total hip arthroplasty. Pelvic tilting affects the position of acetabular component in the sagittal plane of the body as compared with its anatomic position in the pelvis. We suggest a preoperative lateral view of spine-pelvis, in upright and supine position for evaluation of a corrective adaptation of the acetabular cup accordingly with pelvic balance.

  14. Pelvic hydatid cyst with uncommon sciatalgia manifestation: a case report

    Directory of Open Access Journals (Sweden)

    Ghodratolah Maddah


    Full Text Available Background: Hydatid disease or echinococcosis is a common parasitic disease of human and bovine, caused by infection with larva of the cestode echinococcus. Liver is the most common organ that is involved in this disease. Pelvic involvement and neurological symptoms, due to mass effect of pelvic involvement, in lower extremities are very uncommon manifestations of the disease.Case presentation: A forty six year old man was referred to clinic of surgery at Ghaem Hospital, Medical University of Mashhad, Iran. The patient complained about weakness and motor impairment in right lower extremity accompanied by numbness and radicular pain over past two months. Physical examination demonstrated muscular atrophy and reduced muscular strength in right lower extremity. Computed tomography and ultrasonographic studies showed a cystic mass in right side of the pelvic cavity with extention to the sciatic notch and another cystic mass in right gluteal region. Surgical operation revealed a cystic mass deep in pelvic cavity with the extention to the right sciatic notch with compression of nerve roots. The cystic mass was contained of daughter cysts which confirmed the diagnosis of hydatid cyst disease. This diagnosis was confirmed by pathologic assessment.Conclusion: Although uncommon, but hydatid disease can involve the pelvic cavity and make a pelvic, usually cystic, mass; that can make compression on nerve roots and so making neurologic symptoms in lower extremities. So in endemic areas for hydatid disease, such as Iran, pelvic hydatid cysts should be considered as a possible differential diagnosis in patients presenting with the sciatic pain and neurological manifestations in whom a pelvic mass has been found too.

  15. Female Pelvic Vein Embolization: Indications, Techniques, and Outcomes

    Energy Technology Data Exchange (ETDEWEB)

    Lopez, Anthony James, E-mail: [The Imaging Clinic (United Kingdom)


    Until recently, the main indication for pelvic vein embolization (PVE) in women was to treat pelvic venous congestion syndrome (PVC) but increasingly, patients with refluxing pelvic veins associated with leg varicosities are also being treated. A more unusual reason for PVE is to treat pelvic venous malformations, although such lesions may be treated with sclerotherapy alone. Embolotherapy for treating PVC has been performed for many years with several published studies included in this review, whilst an emerging indication for PVE is to treat lower limb varicosities associated with pelvic vein reflux. Neither group, however, has been subjected to an adequate randomized, controlled trial. Consequently, some of the information presented in this review should be considered anecdotal (level III evidence) at this stage, and a satisfactory ‘proof’ of clinical efficacy remains deficient until higher-level evidence is presented. Furthermore, a wide range of techniques not accepted by all are used, and some standardization will be required based on future mandatory prospective studies. Large studies have also clearly shown an unacceptably high recurrence rate of leg varicose veins following venous surgery. Furthermore, minimally or non-invasive imaging is now revealing that there is a refluxing pelvic venous source in a significant percentage of women with de novo leg varicose veins, and many more with recurrent varicosities. Considering that just over half the world’s population is female and a significant number of women not only have pelvic venous reflux, but also have associated leg varicosities, minimally invasive treatment of pelvic venous incompetence will become a common procedure.

  17. Pelvic actinomycosis in association with an intrauterine device. (United States)

    Garland, S M; Rawling, D


    A case of pelvic actinomycosis is described which occurred in association with the use of an intrauterine device (IUD). Initially medical management alone was used, but surgical intervention was necessitated for multiple pelvic abscesses. We would strongly recommend that any IUD be removed should it be associated with actinomyces on genital smears and/or culture. If sepsis is also apparent, IUD removal with use of long-term antibiotics is required.

  18. Transmission block to simplify combined pelvic and inguinal radiation therapy

    Kalnicki, S.; Zide, A.; Maleki, N.; DeWyngaert, J.K.; Lipsztein, R.; Dalton, J.F.; Bloomer, W.D.


    A homogeneous dose distribution of radiation to inguinal lymph nodes and deep pelvic structures can be achieved with use of a transmission block over the central portion of a large anterior pelvic-inguinal portal, together with a smaller posterior field. This relatively simple technique permits individualization of isodose distributions and eliminates the problems of matching abutting portals. Reproducibility of daily setup and optimization of machine utilization are both improved.

  1. Apical vault repair, the cornerstone or pelvic vault reconstruction. (United States)

    Ross, J W


    Pelvic organ prolapse remains a difficult problem for pelvic reconstructive surgery. Before new surgical procedures can be developed a good understanding of pelvic anatomy is necessary. It is widely held that the etiology of pelvic organ prolapse is secondary to stretch neuropathy following childbirth and chronic cough or constipation. Several transvaginal and transabdominal procedures have been developed over the years. With the increasing use of laparoscopy, a new variation on existing culdeplasty techniques has been developed. Following anatomical principles, the apical vault repair reestablishes the pericervical ring at the vaginal apex. The incorporation of pubocervical fascia, uterosacral-cardinal ligament and the rectovaginal fascia provides a strong anchor for the vaginal apex. In addition, the repair should help prevent future transverse cystocele, rectocele, enterocele and apical vault prolapse. Early outcome studies suggest that the apical vault repair should be used routinely with laparoscopic urethropexy, laparoscopic hysterectomy and the repair of pelvic organ prolapse. Good apical vault support is considered the cornerstone of pelvic reconstruction.

  2. Role of pelvic floor in lower urinary tract function. (United States)

    Chermansky, Christopher J; Moalli, Pamela A


    The pelvic floor plays an integral part in lower urinary tract storage and evacuation. Normal urine storage necessitates that continence be maintained with normal urethral closure and urethral support. The endopelvic fascia of the anterior vaginal wall, its connections to the arcus tendineous fascia pelvis (ATFP), and the medial portion of the levator ani muscles must remain intact to provide normal urethral support. Thus, normal pelvic floor function is required for urine storage. Normal urine evacuation involves a series of coordinated events, the first of which involves complete relaxation of the external urethral sphincter and levator ani muscles. Acquired dysfunction of these muscles will initially result in sensory urgency and detrusor overactivity; however, with time the acquired voiding dysfunction can result in intermittent urine flow and incomplete bladder emptying, progressing to urinary retention in severe cases. This review will start with a discussion of normal pelvic floor anatomy and function. Next various injuries to the pelvic floor will be reviewed. The dysfunctional pelvic floor will be covered subsequently, with a focus on levator ani spasticity and stress urinary incontinence (SUI). Finally, future research directions of the interaction between the pelvic floor and lower urinary tract function will be discussed.

  3. Normal Vulvovaginal, Perineal, and Pelvic Anatomy with Reconstructive Considerations (United States)

    Yavagal, Sujata; de Farias, Thais F.; Medina, Carlos A.; Takacs, Peter


    A thorough insight into the female genital anatomy is crucial for understanding and performing pelvic reconstructive procedures. The intimate relationship between the genitalia and the muscles, ligaments, and fascia that provide support is complex, but critical to restore during surgery for correction of prolapse or aesthetic reasons. The external female genitalia include the mons pubis, labia majora and minora, clitoris, vestibule with glands, perineal body, and the muscles and fascia surrounding these structures. Through the perineal membrane and the perineal body, these superficial vulvar structures are structurally related to the deep pelvic muscle levator ani with its fascia. The levator ani forms the pelvic floor with the coccygeus muscle and provides vital support to all the pelvic organs and stability to the perineum. The internal female genital organs include the vagina, cervix, uterus, tubes, and ovaries with their visceral fascia. The visceral fascia also called the endopelvic fascia, surrounds the pelvic organs and connects them to the pelvic walls. It is continuous with the paraurethral and paravaginal fascia, which is attached to the perineal membrane. Thus, the internal and external genitalia are closely related to the muscles and fascia, and work as one functioning unit. PMID:22547969

  4. Enhanced muscle activity during lumbar extension exercise with pelvic stabilization. (United States)

    Lee, Ho-Seong


    The purpose of this study was to investigate whether pelvic stabilization affects multifidus (MF) and iliocostalis lumborum (IL) muscle activities during dynamic extension exercise. Nine males (age, 25.1±6.3 yr; height, 176.6±2.4 cm; body mass, 74.9±6.7 kg) performed an isometric lumbar extension strength test and dynamic exercise in an upright seated position with or without pelvic stabilization. The electromyography and muscle strength of the MF and IL muscles were measured when the subjects performed the isometric lumbar extension strength test at the trunk angle 110°, 146°, and 182°. In addition, the trunk extensor muscle activities were measured using 50% muscle strength of maximum isometric strength during a dynamic trunk extension exercise. The MF and IL muscle activities were significantly higher at 110°, 146°, and 182° with pelvic stabilization than that without pelvic stabilization during the isometric lumbar extension strength test (Plumbar extension exercise with pelvic stabilization may be more effective for MF and IL muscle activity compared to that without pelvic stabilization.

    Full Text Available Universally, high- energy trauma is the major cause of mortality and morbidity in the younger age group. Usually pelvic fractures are caused by high energy trauma. Hence it affects not only the musculoskeletal system, but also the soft tissues and viscera contained in the pelvis leading to increased mortality and morbidity. Management of such patients remains a challenge to the trauma surgeon, even in the most sophisticated trauma centers. The aim of our study is to evaluate the role of external fixation in the management of pelvic fractures, both as a resuscitative measure and definitive treatment of unstable pelvic fractures (Type B & Type C. In our study, all patients underwent stabilization with external fixator and the mortality rate was zero with additional internal fixation with reconstruction plating being done in three patients. The primary advantage of external fixation in pelvic injury is to maintain the reduction by which it produces a tamponade effect and results in reduction in haemorrhage, and helps transportation of the patient. External stabilization for unstable pelvic fractures with external fixator is an established treatment procedure and we in our study confirm the usefulness of the procedure in an emergency situation and can be continued effectively as a definitive management for type B & C Pelvic injuries

  6. The 12-month effects of structured lifestyle advice and pelvic floor muscle training for pelvic organ prolapse

    DEFF Research Database (Denmark)

    Due, Ulla; Brostrøm, Søren; Lose, Gunnar


    INTRODUCTION: We evaluated the 12-month effects of adding pelvic floor muscle training to a lifestyle advice program in women with symptomatic pelvic organ prolapse stage II-III and the number of women who had sought further treatment. MATERIAL AND METHODS: This study was a 12-month follow up...... of a randomized controlled trial comparing a structured lifestyle advice program alone (lifestyle group) or in combination with pelvic floor muscle training (training and lifestyle group). Both programs consisted of six separate group sessions within 12 weeks. RESULTS: Data were available from 83 (76%) of the 109...... surgery. More severe anterior prolapse and more bladder symptoms at the 3-month follow up were significantly associated with having sought further treatment in both groups. CONCLUSIONS: At 12-month follow up, the effects of adding pelvic floor muscle training to a structured lifestyle advice program were...

  7. Pelvic belt effects on pelvic morphometry, muscle activity and body balance in patients with sacroiliac joint dysfunction.

    Directory of Open Access Journals (Sweden)

    Odette Soisson

    Full Text Available The sacroiliac joint (SIJ is frequently involved in low back and pelvic girdle pain. However, morphometrical and functional characteristics related to SIJ pain are poorly defined. Pelvic belts represent one treatment option, but evidence still lacks as to their pain-reducing effects and the mechanisms involved. Addressing these two issues, this case-controlled study compares morphometric, functional and clinical data in SIJ patients and healthy controls and evaluates the effects of short-term pelvic belt application.Morphometric and functional data pertaining to pelvic belt effects were compared in 17 SIJ patients and 17 controls. Lumbar spine and pelvis morphometries were obtained from 3T magnetic resonance imaging. Functional electromyography data of pelvis and leg muscles and center of pressure excursions were measured in one-leg stance. The numerical rating scale was used to evaluate immediate pain-reducing effects.Pelvic morphometry was largely unaltered in SIJ patients and also by pelvic belt application. The angle of lumbar lateral flexion was significantly larger in SIJ patients without belt application. Muscle activity and center of pressure were unaffected by SIJ pain or by belt application in one-leg stance. Nine of 17 patients reported decreased pain intensities under moderate belt application, four reported no change and four reported increased pain intensity. For the entire population investigated here, this qualitative description was not confirmed on a statistical significant level.Minute changes were observed in the alignment of the lumbar spine in the frontal plane in SIJ patients. The potential pain-decreasing effects of pelvic belts could not be attributed to altered muscle activity, pelvic morphometry or body balance in a static short-term application. Long-term belt effects will therefore be of prospective interest.

    The aim of this study was to evaluate the clinical, radiographic and histopathologic features of 23 cases of solitary bone cyst by means of the analysis of radiographs and biopsy specimens in 23 persons visited the Department of Oral and Maxillofacial Radiology, School of Dentistry, Kyung Hee University and Chunbuk National University. The obtained results were as follows; 1. The incidence of solitary bone cyst was almost equal in males (52.2%) and in females(42.8%) and the prevalent age of the solitary bone cyst were the second decade (47.8%) and the third decade (21.7%). 2. In the signs and symptoms of solitary bone cyst, pain or tenderness revealed in 17.4%, swelling revealed in 13.0%, pain and swelling revealed in 21.7%, paresthesia revealed in 4.4% and 43.5% were a symptom and the tooth vitality involved in the solitary bone cyst, 76.5% were posterior and 23.5% were either positive or negative. 3. In the location of the solitary bone cyst, 47.8% present posterior region, 21.7% present anterior region, 21.6% present anterior and posterior region, 4.4% present condylar process area. 4. In the hyperostotic border of the solitary bone cyst, 47.8% were seen entirely, 21.8% were seen partially, and 30.4% were not seen. 5. In the change of tooth, 59.1% were loss of the alveolar lamina dura, 13.6% were root resorption 4.55% were tooth displacement, 4.55% were root resorption and tooth displacement. 6. In the change of cortical bone of the solitary bone cyst, 39.1% were intact and 60.9% were thinning and expansion of cortical bone. 7. In the histopathologic findings of 9 cases, 33.3% were thin connective tissue wall, 11.1% were thickened myxo-fibromatous wall, 55.6% were thickened myxofibromatous wall with dysplastic bone formation.

    Highlights: • Pelvic radiographs with speed class 400 and 800 in follow-up of hip arthroplasty were compared. • Radiographs with reduced dose (800) were not inferior to those with standard dose (400). • We recommend speed class 800 as new reference parameter in these examinations. - Abstract: Objective: Digital plain radiographs of the pelvis are frequently performed in follow-up examinations of patients who received total hip arthroplasty (THA) or osteosynthesis (OS). Thus, the purpose was to reduce the radiation dose and to determine objective quality control criteria to ensure accurate assessment. Materials and methods: Institutional review board approval was obtained. In this prospective randomized study, 289 patients underwent X-ray examination of the pelvis as follow up after receiving THA or OS with standard and reduced dose. The evaluation of the plain radiographs was conducted using the following criteria: bone–implant interface, implant–implant discrimination, implant–surface character and periarticular heterotopic ossification. Two radiologists evaluated these criteria using a score ranging from 1 (definitely assessable) to 4 (not assessable). If a single criterion had been evaluated with a score of 3 or more or more than 2 criteria with 2 points, the radiograph was scored as “not assessable“. The study was designed as non-inferiority-trial. Results: Seven (2.4%) examined X-rays were scored as not assessable. There was no statistical inferiority between the examinations with standard (0.365 mSv) or reduced dose (0.211 mSv). Reduced dose only led to limitations in the evaluation of ceramic components with low clinical impact in most scenarios. Conclusion: Plain radiography of the pelvis in patients with THA or OS can be performed with a dose reduction of about 42% without a loss of important information. The obtained quality control criteria were clinically applicable.

    This study was performed to evaluate the reliability of the identification of anatomical landmarks in panoramic and lateral cephalometric radiographs on a standard medical grade picture archiving communication system (PACS) monitor and a tablet computer (iPad 5). A total of 1000 radiographs, including 500 panoramic and 500 lateral cephalometric radiographs, were retrieved from the de-identified dataset of the archive of the Section of Oral and Maxillofacial Radiology of the University Of Connecticut School Of Dental Medicine. Major radiographic anatomical landmarks were independently reviewed by two examiners on both displays. The examiners initially reviewed ten panoramic and ten lateral cephalometric radiographs using each imaging system, in order to verify interoperator agreement in landmark identification. The images were scored on a four-point scale reflecting the diagnostic image quality and exposure level of the images. Statistical analysis showed no significant difference between the two displays regarding the visibility and clarity of the landmarks in either the panoramic or cephalometric radiographs. Tablet computers can reliably show anatomical landmarks in panoramic and lateral cephalometric radiographs.

  12. Burnout in therapy radiographers in the UK. (United States)

    Probst, H; Griffiths, S; Adams, R; Hill, C


    The 2007 UK National Radiotherapy Advisory Group report indicated that the number and type of staff available is one of the "rate-limiting" steps in improving productivity in radiotherapy departments. Retaining well-trained, satisfied staff is key to meeting the objectives of the report; burnout is an important factor linked to satisfaction and attrition. The results of a survey measuring burnout in a sample of radiotherapists (therapy radiographers) are presented and considered against norms for the health sector and burnout in therapists from Canada and the USA. Case study methodology was used studying six radiotherapy departments selected because of close geographical proximity and differing vacancy rates for radiotherapists. An anonymous survey of radiotherapists used the Maslach Burnout Inventory (MBI) and other workforce-related measures (e.g. job satisfaction scales, measures of professional plateau, intentions to leave, job characteristics and demographic data); the results of the burnout questionnaire alone are presented in this paper. A total of 97 completed questionnaires were returned (representing a 28% response rate). The average score for emotional exhaustion was higher than the MBI norms, with 38% of respondents reporting emotional exhaustion (an element of burnout). The data presented support and validated a previous qualitative study, and highlighted key areas of concern requiring further study. A correlation between burnout and job dissatisfaction and intention to leave was identified; managers may want to consider encouraging role extension and good leadership qualities in treatment unit leaders to minimise the potential for burnout.

  13. Projection angles of mandibular condyles in panoramic and transcranial radiographs

    Nah, Kyung Soo [Pusan National Univ. College of Dentistry, Pusan (Korea, Republic of)


    To evaluate the true projection angles of film-side mandibular condyles in panoramic and transcranial radiographs. 52 panoramic and transcranial radiographs of 4 condyles from two human dry mandibles with gradual horizontal and vertical angle changes were taken. The results were compared with the standard panoramic and transcranial radiographs and the identical pairs were selected. Panoramic radiography projected 10 degree to the film-sided condyles both horizontally and vertically. Transcranial radiography projected 15 degree to the film-sided condyles vertically. The medical and lateral poles were not forming the outline of condylar images in both projections when the horizontal angles of condyles were not sufficiently big enough.

  14. Radiographic artefact due to a faulty lead rubber shield

    Kumar, G. E-mail:; Kamath, V.; Murali, S.R.; Temperley, D


    Radiographic examination is one of the commonest investigations performed in the field of Orthopaedics. There are several pitfalls to be kept in mind while interpreting radiographs in Orthopaedics. Bony or soft tissue lesions can be mimicked by anatomical variations, superimposition of soft tissues, inappropriate radiographic exposure and presence of external radio-opaque substances, to name a few. We present a case, where a faulty lead rubber shield mimicked a fracture of distal end of humerus. Early identification of these abnormalities can avoid distress to and unnecessary investigations of the patient.

  15. Contrast Enhancement of Radiographs Using Shift Invariant Wavelet Transform

    Institute of Scientific and Technical Information of China (English)


    A novel approach using shift invariant wavelet transform is presented for the contrast enhancement of radiographs. By exploiting cross-scale correlation among wavelet coefficients, edge information of radiographic images is extracted and protected, while noise is smoothed out in the wavelet domain. Radiographs are then reconstructed from the transform coefficients modified at multi-scales by nonlinear enhancement operator. The method can achieve effectively contrast enhancement and edge-preserved denoising simultaneously, yet it is capable of giving visually distinct images and offering considerable benefits in medical diagnosis.

Sotomayor Obstetrics and Gynecology Hospital, Guayaquil, EcuadorAbstract: Female genital Actinomyces infection is relatively rare, although strongly related to long-lasting intrauterine contraceptive device (IUD application. An infective pathway has been postulated extending upward from the female perineum to the vagina and cervix. The traumatic effect of the device and a prior infection may contribute to the Actinomyces infection in the female genitalia. This disease is characterized by local swelling, suppuration, abscess formation, tissue fibrosis, tubal-ovarian mass and fistula formation. The infection spreads by contiguity often mimicking the characteristics of a malignant neoplastic process. Currently there is no consensus regarding diagnosis and screening tests, although there seems to be agreement in relation to IUD type, duration, and sexual behavior as major risk factors.Keywords: contraception, intrauterine contraceptive device, pelvic actinomycosis, sexuality

  17. Pelvic inflammatory disease and oral contraceptive use. (United States)

    Feldblum, P J; Burton, N; Rosenberg, M J


    Oral contraceptive use has been shown to protect against gonococcal pelvic inflammatory disease (PID), but the effect on chlamydial PID is uncertain. Chlamydia infection is rising in incidence and has become the major cause of PID in many areas. PID may cause infertility, impairing the future reproduction of women. Previous studies on oral contraceptives and PID relied on hospitalized women, which may have biased the sample to include mainly gonococcal PID. Several studies show increased risk of endocervical chlamydia infection in users of oral contraceptives. The postulated mechanism is cervical ectopy, exposing more squamous epithelium to the organisms. Nevertheless, there is evidence indicating that despite the increased incidence of endocervical infection, oral contraceptives may inhibit the organisms from ascending, thus still offering a protective affect against both gonococcal and chlamydial PID. Future research must focus on the prevalence of chlamydia infection in Africa, and the natural history of the illness. The effect of different types of oral contraceptives on chlamydia infection must be evaluated.

    Operative treatment of an intra-articular distal radius fracture is one of the most common procedures in orthopedic and hand surgery. The intra- and interobserver agreement of common radiographical measurements of these fractures using cone beam computed tomography (CBCT) and plain radiographs were evaluated. Thirty-seven patients undergoing open reduction and volar fixation for a distal radius fracture were studied. Two radiologists analyzed the preoperative radiographs and CBCT images. Agreement of the measurements was subjected to intra-class correlation coefficient and the Bland-Altman analyses. Plain radiographs provided a slightly poorer level of agreement. For fracture diastasis, excellent intraobserver agreement was achieved for radiographs and good or excellent agreement for CBCT, compared to poor interobserver agreement (ICC 0.334) for radiographs and good interobserver agreement (ICC 0.621) for CBCT images. The Bland-Altman analyses indicated a small mean difference between the measurements but rather large variation using both imaging methods, especially in angular measurements. For most of the measurements, radiographs do well, and may be used in clinical practice. Two different measurements by the same reader or by two different readers can lead to different decisions, and therefore a standardization of the measurements is imperative. More detailed analysis of articular surface needs cross-sectional imaging modalities. (orig.)

  19. Do elite athletes experience low back, pelvic girdle and pelvic floor complaints during and after pregnancy? (United States)

    Bø, K; Backe-Hansen, K L


    The aim of the present investigation was to study prevalence of low back pain, pelvic girdle pain (PGP) and pelvic floor disorders during pregnancy and after childbirth in elite athletes. A postal questionnaire was sent to all elite athletes who had given birth registered with The Norwegian Olympic Committee and Confederation of Sports (n=40). Eighty age-matched women served as the control group. The response rates were 77.5% and 57.5% in the elite athletes and control groups, respectively. There were no significant differences in the prevalence of low back and PGP, urinary or fecal incontinence among elite athletes and controls at any time point. The prevalence of low back pain without radiation to the leg in elite athletes was 25.8%, 18.5%, 9.7% and 29% the year before pregnancy, during pregnancy, 6 weeks postpartum and at the time of completing the questionnaire, respectively. The prevalence of PGP was 0, 29.6%, 12.9% and 19.4%. Prevalence of stress urinary incontinence was 12.9%, 18.5%, 29% and 35.5%. None of the elite athletes had fecal incontinence at any time point. There were no differences in mode of delivery or birthweight between elite athletes and controls. The elite athletes had a significantly lower body mass index at 6 weeks postpartum and at present compared with the control group.

  20. Spine lateral flexion strength development differences between exercises with pelvic stabilization and without pelvic stabilization (United States)

    Straton, Alexandru; Gidu, Diana Victoria; Micu, Alexandru


    Poor lateral flexor muscle strength can be an important source of lumbar/thoracic back pain in women. The purpose of this study was to evaluate pelvic stabilization (PS) and no pelvic stabilization (NoPS) lateral flexion strength exercise training on the development of isolated right and left lateral flexion strength. Isometric torque of the isolated right and left lateral flexion muscles was measured at two positions (0° and 30° opposed angle range of motion) on 42 healthy women before and after 8 weeks of PS and NoPS lateral flexion strength exercise training. Subjects were assigned in three groups, the first (n=14) trained 3 times/week with PS lateral flexion strength exercise, the second (n=14) trained 3 times/week with NoPS lateral flexion strength exercise and the third (control, n=14) did not train. Post training isometric strength values describing PS and NoPS lateral flexion strength improved in greater extent for the PS lateral flexion strength exercise group and in lesser extent for the NoPS lateral flexion strength exercise group, in both angles (p<0.05) relative to controls. These data indicate that the most effective way of training the spine lateral flexion muscles is PS lateral flexion strength exercises; NoPS lateral flexion strength exercises can be an effective way of training for the spine lateral flexion muscles, if there is no access to PS lateral flexion strength training machines.

  1. Local diagnostic reference level based on size-specific dose estimates: Assessment of pediatric abdominal/pelvic computed tomography at a Japanese national children's hospital

    A child's body size is not accurately reflected by volume CT dose index (CTDI{sub vol}) and dose-length product (DLP). Size-specific dose estimation (SSDE) was introduced recently as a new index of radiation dose. However, it has not yet been established as a diagnostic reference level (DRL). To calculate the SSDE of abdominal/pelvic CT and compare the SSDE with CTDI{sub vol}. To calculate the DRLs of CTDI{sub vol} and SSDE. Our hypotheses are: SSDE values will be greater than CTDI{sub vol}, and our DRL will be smaller than the known DRLs of other countries. The CTDI{sub vol} and DLP of 117 children who underwent abdominal/pelvic CT were collected retrospectively. The SSDE was calculated from the sum of the lateral and anteroposterior diameters. The relationships between body weight and effective diameter and between effective diameter and CTDI{sub vol}/SSDE were compared. Further, the local DRL was compared with the DRLs of other countries. Body weight and effective diameter and effective diameter and SSDE were positively correlated. In children ages 1, 5 and 10 years, the SSDE is closer to the exposure dose of CTDI{sub vol} for the 16-cm phantom, while in children ages 15 years, the SSDE falls between CTDI{sub vol} for the 16-cm phantom and that for the 32-cm phantom. The local DRL was lower than those of other countries. With SSDE, the radiation dose increased with increasing body weight. Since SSDE takes body size into account, it proved to be a useful indicator for estimating the exposure dose. (orig.)

    Xin-Bao Wu


    Full Text Available Background: Old pelvis fractures are among the most challenging fractures to treat because of their complex anatomy, difficult-to-access surgical sites, and the relatively low incidence of such cases. Proper evaluation and surgical planning are necessary to achieve the pelvic ring symmetry and stable fixation of the fracture. The goal of this study was to assess the use of three-dimensional (3D printing techniques for surgical management of old pelvic fractures. Methods: First, 16 dried human cadaveric pelvises were used to confirm the anatomical accuracy of the 3D models printed based on radiographic data. Next, nine clinical cases between January 2009 and April 2013 were used to evaluate the surgical reconstruction based on the 3D printed models. The pelvic injuries were all type C, and the average time from injury to reconstruction was 11 weeks (range: 8-17 weeks. The workflow consisted of: (1 Printing patient-specific bone models based on preoperative computed tomography (CT scans, (2 virtual fracture reduction using the printed 3D anatomic template, (3 virtual fracture fixation using Kirschner wires, and (4 preoperatively measuring the osteotomy and implant position relative to landmarks using the virtually defined deformation. These models aided communication between surgical team members during the procedure. This technique was validated by comparing the preoperative planning to the intraoperative procedure. Results: The accuracy of the 3D printed models was within specification. Production of a model from standard CT DICOM data took 7 hours (range: 6-9 hours. Preoperative planning using the 3D printed models was feasible in all cases. Good correlation was found between the preoperative planning and postoperative follow-up X-ray in all nine cases. The patients were followed for 3-29 months (median: 5 months. The fracture healing time was 9-17 weeks (mean: 10 weeks. No delayed incision healing, wound infection, or nonunions occurred. The

    Pulmonary artery hypertension with chronic pulmonary embolism is an uncommon entity that is potentially treatable with pulmonary embolectomy. Although the classic radiographic features have been described, several recent investigators report a significant percentage of these patients with normal chest radiographs. In a series of 22 patients, no normal radiographs were seen. Findings included cardiomegaly (86.4%) with right-sided enlargement (68.4%), right descending pulmonary artery enlargement (54.5%), azygos vein enlargement (27.3%), mosaic oligemia (68.2%), chronic volume loss (27.3%), atelectasis and/or effusion (22.7%), and pleural thickening (13.6%). Good correlation with specific areas of diminished vascularity was seen on chest radiographs compared with pulmonary angiograms.

  5. Analyzing edge detection techniques for feature extraction in dental radiographs

    Directory of Open Access Journals (Sweden)

    Kanika Lakhani


    Full Text Available Several dental problems can be detected using radiographs but the main issue with radiographs is that they are not very prominent. In this paper, two well known edge detection techniques have been implemented for a set of 20 radiographs and number of pixels in each image has been calculated. Further, Gaussian filter has been applied over the images to smoothen the images so as to highlight the defect in the tooth. If the images data are available in the form of pixels for both healthy and decayed tooth, the images can easily be compared using edge detection techniques and the diagnosis is much easier. Further, Laplacian edge detection technique is applied to sharpen the edges of the given image. The aim is to detect discontinuities in dental radiographs when compared to original healthy tooth. Future work includes the feature extraction on the images for the classification of dental problems.

    Albers, Brittany K.; Garner, Hillary W. [Mayo Clinic, Department of Radiology, Jacksonville, FL (United States); Sluzevich, Jason C. [Mayo Clinic, Department of Dermatology, Jacksonville, FL (United States)


    Sarcoidosis is a granulomatous disease which can affect multiple organ systems. Clinical and radiologic manifestations depend on the organ system involved and the chronicity of disease. Nail involvement in sarcoidosis is rare, but is clinically relevant as it indicates chronic systemic disease. Nail abnormalities can be identified radiographically, and when seen in patients with known or suspected sarcoidosis, should prompt careful evaluation of the underlying bone for osseous involvement. We describe a case of sarcoidosis with radiographic findings in the nails and distal phalangeal tufts, which were indicative of nail and osseous sarcoid involvement and strongly supported the presence of chronic systemic disease. Although the nail findings resolved clinically and on radiographs after treatment, the osseous findings showed only minimal improvement. To our knowledge, the radiographic findings of nail sarcoidosis have not been previously addressed in the literature. (orig.)

    Background: Pediatric patients are being treated with bisphosphonates for low bone mineral density. Skeletal radiographic findings have been described with bisphosphonates given orally and intravenously. Objective: To determine and describe the radiographic findings of cyclic intravenous bisphosphonate therapy in the growing skeleton. Materials and methods: Retrospective review of radiographs of 32 patients with osteogenesis imperfecta or cerebral palsy treated with intravenous bisphosphonates on a quarterly schedule. Results: Principal observations were metaphyseal bands and increased bone mineral density. The bands varied in spacing according to the age of the patient, rate of growth, and the location of the metaphysis. Fractures continued to be seen in patients with osteogenesis imperfecta. Conclusion: Cyclic bisphosphonate therapy results in distinctive radiographic findings in the growing skeleton. (orig.)

    Staroba, J. F.; Knoerzer, T. W.


    This report covers the radiographic and densitometric techniques used as part of a quality verification program for CP-5 reactor fuel by the Nondestructive Assay Section of the Special Materials Division. Other nondestructive tests used were ultrasonic and gamma-ray spectrometry. The main objectives were to perform a one-hundred percent radiographic inspection of the fuel tubes and to derive a quantitative relationship between fuel thickness and film density with the use of fabricated fuel step wedges. By the use of tangential x-ray techniques, measurements were made of fuel peaks or ''hot spots'' that protruded above the main fuel line. Other general problems in radiographic inspection and solutions for the upgrading of the total radiographic inspection program are also discussed.

    The aim of this study is the optimization of radiographic images for the pediatric patients in the age range between 0 and 1 years old, through Optical Density Ratio (ODR), considering that pediatric patients are overexposed to radiation in the repeated attempts to obtain radiographic images considered of good quality. The optimization of radiographic techniques was carried out with the RAP-PEPP (Realistic Analytical Phantom coupled to homogeneous Phantom Equivalent to Pediatric Patient) phantom in two incubators and one cradle. The data show that the clinical routine radiographic techniques generate low-quality images at up to 18.8% when evaluated by the ODRs, and increases in doses up to 60% when compared to the optimized techniques doses.

  10. Radiographic and scintigraphic evaluation of total knee arthroplasty

    Energy Technology Data Exchange (ETDEWEB)

    Schneider, R.; Soudry, M.


    Various radiographic and scintigraphic methods are used to supplement clinical findings in the evaluation of total knee arthroplasty and its complications. Serial roentgenograms offer reliable information for diagnosing mechanical loosening. Wide and extensive radiolucency at the cement-bone interface and shift in position and alignment of prosthetic components can be seen in almost all cases by the time revision is necessary. Radiographic abnormalities are usually not present in acute infection, but are often present in chronic infection. Bone scanning has a high sensitivity for diagnosis of infection or loosening, but is nonspecific because increased uptake is often present around asymptomatic total knee arthroplasties with normal radiographs. Differential bone and Gallium scanning and scanning with Indium 111-labeled leukocytes have a greater specificity for diagnosis of infection than does bone or Gallium scanning alone. Routine radiographic and scintigraphic studies have shown a high incidence of deep vein thrombosis in the calf after total knee arthroplasty. Clinically significant pulmonary embolization is infrequent.

  12. Practical guidelines for radiographers to improve computed radiography image quality. (United States)

    Pongnapang, N


    Computed Radiography (CR) has become a major digital imaging modality in a modern radiological department. CR system changes workflow from the conventional way of using film/screen by employing photostimulable phosphor plate technology. This results in the changing perspectives of technical, artefacts and quality control issues in radiology departments. Guidelines for better image quality in digital medical enterprise include professional guidelines for users and the quality control programme specifically designed to serve the best quality of clinical images. Radiographers who understand technological shift of the CR from conventional method can employ optimization of CR images. Proper anatomic collimation and exposure techniques for each radiographic projection are crucial steps in producing quality digital images. Matching image processing with specific anatomy is also important factor that radiographers should realise. Successful shift from conventional to fully digitised radiology department requires skilful radiographers who utilise the technology and a successful quality control program from teamwork in the department.

    Background Patients with pelvic fractures are often treated in hospitals without the capacity to implement an open reduction internal fixation (ORIF).This often leads to pelvic malunion in patients with unstable pelvic fracture,shock or even death due to uncontrollable pelvic hemorrhage and unstable hemodynamics.This study explored the role of early external fixation (within 7 days) for patients with unstable pelvic fractures.Methods A retrospective analysis was conducted on 32 patients with unstable pelvic fractures treated with early external fixation from January 2005 to January 2010 (file type B:18 cases; C:14 cases).The study comprised 28 males and 4 females,with a mean age of (32±8) years (range,21-56 years).Of these patients,22 were treated with emergency pelvic external fixation and 10 were treated with external fixation within 1-7 days.Fifteen cases suffered traumatic hemorrhagic shock.A statistical analysis was conducted to compare fluid infusion and blood transfusion volumes within the first 24 hours of these shock patients with another cohort of patients treated without early external fixation from January 1993 to January 1998.Results The average follow-up was (34.7±14.6) months (range,6-66 months).Six to eight weeks after external fixation,patients could walk with crutches; by 12 weeks,external fixation was removed and all fractures had healed.Seven patients presented with sequelae,including 3 patients with long-term lumbosacral pain,3 patients with erectile dysfunction and 1 patient with Morel-Lavallee lesion and other complications.The 15 shock patients in this study (2005-2010 group) required significantly lower volumes of fluid infusion and blood transfusion (Pfluid=0.000;Ptransfusion=0.000) as compared to the 1993-1998 cohort.Conclusions The early application of external fixation in unstable pelvic fracture patients positively affects hemodynamic stability,with outstanding efficacy as a final fixation option for unstable pelvic fractures.

  15. Expression of estrogen receptors in the pelvic floor of pre- and post-menopausal women presenting pelvic organ prolapse

    Directory of Open Access Journals (Sweden)

    Marie Laure Kottler


    Full Text Available The precise role of estrogen in the pathogenesis of pelvic organ prolapse (POP is still unclear, while the results concerning the effect of selective estrogen receptor modulators on pelvic organ prolapse are contradictory. Our aim was to test whether alteration in the expression of estrogen receptors in the pelvic floor of preand post-menopausal women is related to genital prolapse status. The mRNA levels of ERα and ERβ in 60 biopsy specimens were measured. Significantly higher expression of ERα and higher ERα/ERβ ratio were demonstrated in post-menopausal women compared to pre-menopausal women. Higher expression of ERα and higher ERα/ERβ ratio were detected in all studied groups with POP, thus it did not reach significance in the post-menopausal group. Pre-menopausal and post-menopausal women presenting pelvic organ prolapse had no difference in the ERα expression. Our preliminary study may indicate that pelvic organ prolapse is associated with higher expression of ERα/ERβ in the pelvic floor of both pre- and post-menopausal women; thus not reaching statistical significance in the post-menopausal women was probably due to the group’s size. We believe that the inevitable changes in the estrogen receptor expression over women’s different lifetimes may affect the risk of genital prolapse progression, and might contribute to the further search for appropriate selective estrogen receptor modulators as a treatment for women with pelvic organ prolapse.

    Thomas Torstensson

    Full Text Available To describe referred pain patterns provoked from intra-pelvic structures in women with chronic pelvic pain (CPP persisting after childbirth with the purpose to improve diagnostics and give implications for treatment.In this descriptive and comparative study 36 parous women with CPP were recruited from a physiotherapy department waiting list and by advertisements in newspapers. A control group of 29 parous women without CPP was consecutively assessed for eligibility from a midwifery surgery. Inclusion criterion for CPP was: moderate pain in the sacral region persisting at least six months after childbirth confirmed by pelvic pain provocation tests. Exclusion criteria in groups with and without CPP were: persistent back or pelvic pain with onset prior to pregnancy, previous back surgery and positive neurological signs. Pain was provoked by palpation of 13 predetermined intra-pelvic anatomical landmarks. The referred pain distribution was expressed in pain drawings and described in pain maps and calculated referred pain areas.Pain provoked by palpation of the posterior intra-pelvic landmarks was mostly referred to the sacral region and pain provoked by palpation of the ischial and pubic bones was mostly referred to the groin and pubic regions, with or without pain referred down the ipsilateral leg. The average pain distribution area provoked by palpation of all 13 anatomical landmarks was 30.3 mm² (19.2 to 53.7 in women with CPP as compared to 3.2 mm² (1.0 to 5.1 in women without CPP, p< 0.0001.Referred pain patterns provoked from intra-pelvic landmarks in women with CPP are consistent with sclerotomal sensory innervation. Magnification of referred pain patterns indicates allodynia and central sensitization. The results suggest that pain mapping can be used to evaluate and confirm the pain experience among women with CPP and contribute to diagnosis.

    High speed x-ray imaging can be an important tool for observing internal processes in a wide range of applications. In this paper we describe preliminary implementation of a system having the eventual goal of observing the internal dynamics of bone and joint reactions during loading. Two Los Alamos National Laboratory (LANL) gated and image intensified camera systems were used to record images from an x-ray image convertor tube to demonstrate the potential of high frame-rate digital radiographic videography in the analysis of bone and joint dynamics of the human body. Preliminary experiments were done at LANL to test the systems. Initial high frame-rate imaging (from 500 to 1000 frames/s) of a swinging pendulum mounted to the face of an X-ray image convertor tube demonstrated high contrast response and baseline sensitivity. The systems were then evaluated at the Motion Analysis Laboratory of Henry Ford Health Systems Bone and Joint Center. Imaging of a 9 inch acrylic disk with embedded lead markers rotating at approximately 1000 RPM, demonstrated the system response to a high velocity/high contrast target. By gating the P-20 phosphor image from the X-ray image convertor with a second image intensifier (II) and using a 100-microsecond wide optical gate through the second II, enough prompt light decay from the x-ray image convertor phosphor had taken place to achieve reduction of most of the motion blurring. Measurement of the marker velocity was made by using video frames acquired at 500 frames/s. The data obtained from both experiments successfully demonstrated the feasibility of the technique. Several key areas for improvement are discussed along with salient test results and experiment details.

    The 1980 ILO classification of radiographs of the pneumoconioses has undergone revision and improvement in response to increases in knowledge and international concerns. Its goal is to standardize the reading and reporting of radiographic manifestations of the inhalation of dust so that international epidemiologic comparisons are possible. It remains an imperfect instrument, but "... although total elimination of variation is impossible, some measure of control can be achieved."

    Pelvic lymphocele, also known as lymphocyst, is a cystic structure caused by lymphatic injury usually secondary to pelvic lymphadenectomy and renal transplantation. Lymphoceles can cause morbidity and rarely mortality by compression of adjacent structures and infectious complications. This review discusses etiology and treatment options for pelvic lymphoceles including surgical and percutaneous methods with emphasis on percutaneous techniques particularly in conjunction with sclerotherapy. Percutaneous catheter drainage with sclerotherapy procedure with various sclerosing agents is described in detail. Ethanol, povidone-iodine, tetracycline, doxycycline, bleomycin, talc and fibrin glue can be used as sclerosing agents. Combination of sclerosing agents to percutaneous catheter drainage significantly improves success rate in the treatment of pelvic lymphoceles. Infected lymphoceles are usually treated solely with percutaneous catheter drainage. Percutaneous treatment can be tailored according to volume of lymphoceles. We generally prefer single session sclerotherapy and 1 day catheter drainage in lymphoceles less than 150 mL, and larger ones are treated by multi-session sclerotherapy until daily drainage decreases below 10 mL. Percutaneous treatment preferably with sclerotherapy should be considered as the first-line treatment modality for pelvic lymphoceles due to its effectiveness, widespread applicability on an outpatient basis, ease of procedure and low complication rate.

    Full Text Available A normal motion and segmental interrelationship has been determined as a significant factor in normal function. Yet, the relationship between distal segments and pelvic alignment needs further investigation. The aim of this study was to investigate the interrelationship between distal and proximal lower extremity segments while standing and during induced feet hyperpronation. Changes in alignment of the pelvis and lower extremities were measured at a gait laboratory using the VICON 612 computerized motion analysis system. Thirty-five healthy volunteer subjects were recruited. Four randomized repeated-measure standing modes were used: standing directly on the floor and then on three wedges angled at 10°, 15° and 20° to induce bilateral hyperpronation for 20 seconds. A significant (p<0.05 bi-variate relationship was found between the anterior pelvic tilt and thigh internal rotation, in all four standing positions (.41≤r≤.46, in all p<0.014. A combined effect of rotational alignment between segments and the cumulative effect of foot hyperpronation on pelvic tilt revealed that only the shank significantly affected pelvic alignment, acting as a mediator between a foot and a thigh with the thigh having a crude significant effect on the pelvis. When internal rotation of the shank occurs, calcaneal eversion couples with thigh internal rotation and anterior pelvic tilt. It can be concluded that in response to induced hyperpronation, the shank is a pivotal segment in postural adjustment.

  5. Pelvic Floor Muscle Training: Underutilization in the USA. (United States)

    Lamin, Eliza; Parrillo, Lisa M; Newman, Diane K; Smith, Ariana L


    Pelvic floor disorders are highly prevalent in women of all ages and can greatly impair quality of life. Pelvic floor muscle training (PFMT) is a viable treatment option for several pelvic floor conditions including urinary incontinence and pelvic organ prolapse. PFMT is a program of therapy initiated by an experienced clinician (e.g., women's health or urology nurse practitioner (NP), physical therapist (PT)) that involves exercises for women with stress urinary incontinence (UI) and exercises combined with behavioral or conservative treatments (lifestyle changes, bladder training with urge suppression) for women with urgency or mixed UI. These exercise programs are more comprehensive than simple Kegel exercises. Despite evidence-based research indicating the efficacy and cost-effectiveness for treatment of urinary incontinence, PFMT is not commonly used as a first-line treatment in clinical practice in the USA (Abrams et al., 2012). This article will review PFMT for the treatment of UI and pelvic organ prolapse (POP) and theorize how this conservative therapy can be utilized more effectively in the USA.

  6. Utilization of Human-Like Pelvic Rotation for Running Robot

    Directory of Open Access Journals (Sweden)

    Takuya eOtani


    Full Text Available The spring loaded inverted pendulum (SLIP is used to model human running. It is based on a characteristic feature of human running, in which the linear-spring-like motion of the standing leg is produced by the joint stiffness of the knee and ankle. Although this model is widely used in robotics, it does not include human-like pelvic motion. In this study, we show that the pelvis actually contributes to the increase in jumping force and absorption of landing impact. On the basis of this finding, we propose a new model, SLIP2 (spring loaded inverted pendulum with pelvis, to improve running in humanoid robots. The model is composed of a body mass, a pelvis, and leg springs, and, it can control its springs while running by use of pelvic movement in the frontal plane. To achieve running motions, we developed a running control system that includes a pelvic oscillation controller to attain control over jumping power and a landing placement controller to adjust the running speed. We also developed a new running robot by using the SLIP2 model and performed hopping and running experiments to evaluate the model. The developed robot could accomplish hopping motions only by pelvic movement. The results also established that the difference between the pelvic rotational phase and the oscillation phase of the vertical mass displacement affects the jumping force. In addition, the robot demonstrated the ability to run with a foot placement controller depending on the reference running speed.

  7. Automatic detection of scoliotic curves in posteroanterior radiographs. (United States)

    Duong, Luc; Cheriet, Farida; Labelle, Hubert


    Spinal deformities are diagnosed using posteroanterior (PA) radiographs. Automatic detection of the spine on conventional radiographs would be of interest to quantify curve severity, would help reduce observer variability and would allow large-scale retrospective studies on radiographic databases. The goal of this paper is to present a new method for automatic detection of spinal curves from a PA radiograph. A region of interest (ROI) is first extracted according to the 2-D shape variability of the spine obtained from a set of PA radiographs of scoliotic patients. This region includes 17 bounding boxes delimiting each vertebral level from T1 to L5. An adaptive filter combining shock with complex diffusion is used to individually restore the image of each vertebral level. Then, texture descriptors of small block elements are computed and submitted for training to support vector machines (SVM). Vertebral body's locations are thereby inferred for a particular vertebral level. The classifications of block elements for all 17 SVMs are identified in the image and a voting system is introduced to cumulate correctly predicted blocks. A spline curve is then fitted through the centers of the predicted vertebral regions and compared to a manual identification using a Student t-test. A clinical validation is performed using 100 radiographs of scoliotic patients (not used for training) and the detected spinal curve is found to be statistically similar (p < 0.05) in 93% of cases to the manually identified curve.

  8. Segmentation and determination of joint space width in foot radiographs (United States)

    Schenk, O.; de Muinck Keizer, D. M.; Bernelot Moens, H. J.; Slump, C. H.


    Joint damage in rheumatoid arthritis is frequently assessed using radiographs of hands and feet. Evaluation includes measurements of the joint space width (JSW) and detection of erosions. Current visual scoring methods are timeconsuming and subject to inter- and intra-observer variability. Automated measurement methods avoid these limitations and have been fairly successful in hand radiographs. This contribution aims at foot radiographs. Starting from an earlier proposed automated segmentation method we have developed a novel model based image analysis algorithm for JSW measurements. This method uses active appearance and active shape models to identify individual bones. The model compiles ten submodels, each representing a specific bone of the foot (metatarsals 1-5, proximal phalanges 1-5). We have performed segmentation experiments using 24 foot radiographs, randomly selected from a large database from the rheumatology department of a local hospital: 10 for training and 14 for testing. Segmentation was considered successful if the joint locations are correctly determined. Segmentation was successful in only 14%. To improve results a step-by-step analysis will be performed. We performed JSW measurements on 14 randomly selected radiographs. JSW was successfully measured in 75%, mean and standard deviation are 2.30+/-0.36mm. This is a first step towards automated determination of progression of RA and therapy response in feet using radiographs.

  9. MR imaging of pelvic lymph nodes in primary pelvic carcinoma with ultrasmall superparamagnetic iron oxide (Combidex): preliminary observations. (United States)

    Harisinghani, M G; Saini, S; Slater, G J; Schnall, M D; Rifkin, M D


    The potential of ultrasmall superparamagnetic iron oxide (Combidex)-enhanced MRI of pelvic lymph nodes in patients with primary pelvic carcinoma is evaluated. Fifteen histologically classified lymph nodes in six patients with known primary pelvic cancer (four prostate; one rectum; one uterus) were evaluated with T2-weighted fast spin-echo (FSE) and T2*-weighted gradient-echo (GRE) MRI at 1.5T 12 to 48 hours after intravenous administration of Combidex at a dose of 1.7 mg Fe/kg. Quantitative image evaluation was performed by comparing signal intensity of individual nodes on pre- and postcontrast images. All patients proceeded to pelvic lymph-node biopsy or surgical dissection, where six were found to be benign and nine were malignant. Of the 15 lymph nodes, four nodes showed a decrease in signal intensity. Of these, three, in which signal loss was homogenous were benign, and one, in which the signal-intensity decrease was heterogeneous, was malignant (micrometastases). No signal change was noted in 11 of 15 lymph nodes of which three were benign (inflammatory) and eight were malignant. Combidex is a promising MR contrast agent for evaluating pelvic lymph nodes. Our preliminary observations suggest that the agent is most useful for classifying normal lymph nodes.

    Pelvic inflammatory disease (PID) has remarkably influenced female reproductive health. There is significant relationship between the incidence of PID outbreaking and its further sequela, such as chronic pelvic pain. Diagnostic Laparoscopy is a gold standard in evaluation of chronic pelvic pain. The patients who underwent a laparoscopic operation would have a decrease in the amount of pelvic pain. Besides, application of oral drugs and physical therapy are also infective ways in treatment of chronic pelvic pain.%盆腔炎性疾病严重影响广大女性的生殖健康,若不能及时治疗,易引起后遗病变.慢性盆腔痛是盆腔炎性疾病所引起的后遗病变之一.诊断性腹腔镜是目前评价慢性盆腔痛原因的有效方法,可在进行诊断同时对盆腔病变进行手术治疗.此外,口服药物、理疗等方法也可有效缓解盆腔疼痛.

  11. The Number of Positive Pelvic Lymph Nodes and Multiple Groups of Pelvic Lymph Node Metastasis Influence Prognosis in Stage IA-IIB Cervical Squamous Cell Carcinoma

    Directory of Open Access Journals (Sweden)

    Yu Liu


    Full Text Available Background: Pelvic lymph node metastasis (LNM is an important prognostic factor in cervical cancer. Cervical squamous cell carcinoma accounts for approximately 75-80% of all cervical cancers. Analyses of the effects of the number of positive lymph nodes (LNs, unilateral versus bilateral pelvic LNM and a single group versus multiple groups of pelvic LNM on survival and recurrence of cervical squamous cell carcinoma are still lacking. The study aimed to analyze the effects of the number of positive pelvic LNs and a single group versus multiple groups of pelvic LNM on survival and recurrence. Methods: We performed a retrospective review of 296 patients diagnosed with Stage IA-IIB cervical squamous cell carcinoma who received extensive/sub-extensive hysterectomy with pelvic lymphadenectomy/pelvic LN sampling at Peking University People′s Hospital from November 2004 to July 2013. Ten clinicopathological variables were evaluated as risk factors for pelvic LNM: Age at diagnosis, gravidity, clinical stage, histological grade, tumor diameter, lymph-vascular space involvement (LVSI, depth of cervical stromal invasion, uterine invasion, parametrial invasion, and neoadjuvant chemotherapy. Results: The incidence of pelvic LNM was 20.27% (60/296 cases. Pelvic LNM (P = 0.00 was significantly correlated with recurrence. Pelvic LNM (P = 0.00, the number of positive pelvic LNs (P = 0.04 and a single group versus multiple groups of pelvic LNM (P = 0.03 had a significant influence on survival. Multivariate analysis revealed that LVSI (P = 0.00, depth of cervical stromal invasion (P = 0.00 and parametrial invasion (P = 0.03 were independently associated with pelvic LNM. Conclusions: Patients with pelvic LNM had a higher recurrence rate and poor survival outcomes. Furthermore, more than 2 positive pelvic LNs and multiple groups of pelvic LNM appeared to identify patients with worse survival outcomes in node-positive IA-IIB cervical squamous cell carcinoma.

  12. Tomographical anatomy of the pelvis, pelvic floor, and related structures. (United States)

    Fröhlich, B; Hötzinger, H; Fritsch, H


    The sectional anatomy of the pelvic floor was studied in plastinated sections of adult pelves by computed tomography and by magnetic resonance imaging. In sectional anatomy, the levator ani is composed of three portions that can be clearly distinguished by their planes of cleavage and by the course of their fiber bundles. No muscular connections are found between the levator ani portions and the pelvic organs. The fascia of the levator ani in always interposed between the muscle and the pelvic organs. The sectional anatomy of the sphincter ani externus reveals a subdivision into a subcutaneous and a deep portion. Although the puborectalis portion of the levator ani and the deep portion of the sphincter ani externus are more or less continuous, in sectional anatomy they can be distinguished due to their different origins and attachments.

  13. Organising a clinical service for patients with pelvic floor disorders. (United States)

    Chatoor, Dave; Soligo, Marco; Emmanuel, Anton


    The evolution of the multidisciplinary approach to the management of chronic conditions is a reflection of how medicine has evolved from a singular to a plural effort recognising the complex causations and consequences of such disorders. This thinking should not be confined to tertiary centres alone and should be adapted where local expertise is available. Such an approach is especially important in pelvic floor disorders, where the correlation between structure and function is not always straightforward. There is a need to avoid over-investigation by accurate clinical assessment allied to tailored investigation, leading to a step-wise approach to treatment (which may include behavioural, physiotherapy, medical or surgical management). The algorithms here on faecal incontinence, obstetric trauma, pelvic floor prolapse and chronic pelvic pain attempt to provide such a logical approach to patients.

    The aim of this study was to demonstrate and evaluate the ultrasound-guided drainage of deep pelvic abscesses in which transabdominal percutaneous access could not be performed because of overlying structures. A retrospective analysis of 32 consecutive patients with 33 deep pelvic abscesses...... (median diameter 7 cm), 19 were treated with catheter drainage and 18 of these cases resulted in favorable clinical outcomes. Of the smaller abscesses (median diameter 4 cm), 14 were treated with needle drainage. In two of these cases, follow-up US showed that a repeat puncture and drainage was necessary...... and the subsequent in-dwelling catheter period, there were no serious complications related to the drainage procedures. We conclude that ultrasound-guided transrectal, transvaginal, transperineal and transgluteal drainage of deep pelvic abscesses are safe and effective treatment approaches. Based on our findings...

    Endometriosis is characterized by the presence of normal endometrial tissue outside the uterine cavity. In patients with deep pelvic endometriosis, uterosacral ligaments, rectum, rectovaginal septum, vagina or bladder may be involved. Clinical manifestations may be variable, including pelvic pain, dysmenorrhea, dyspareunia, urinary symptoms and infertility. Complete surgical excision is the gold standard for treating this disease, and hence the importance of the preoperative work-up that usually is limited to an evaluation of sonographic and clinical data. Magnetic resonance imaging is of paramount importance in the diagnosis of endometriosis, considering its high accuracy in the identification of lesions intermingled with adhesions, and in the determination of peritoneal lesions extent. The present pictorial review describes the main magnetic resonance imaging findings in deep pelvic endometriosis. (author)

  18. Development and evolution of the muscles of the pelvic fin.

    Directory of Open Access Journals (Sweden)

    Nicholas J Cole


    Full Text Available Locomotor strategies in terrestrial tetrapods have evolved from the utilisation of sinusoidal contractions of axial musculature, evident in ancestral fish species, to the reliance on powerful and complex limb muscles to provide propulsive force. Within tetrapods, a hindlimb-dominant locomotor strategy predominates, and its evolution is considered critical for the evident success of the tetrapod transition onto land. Here, we determine the developmental mechanisms of pelvic fin muscle formation in living fish species at critical points within the vertebrate phylogeny and reveal a stepwise modification from a primitive to a more derived mode of pelvic fin muscle formation. A distinct process generates pelvic fin muscle in bony fishes that incorporates both primitive and derived characteristics of vertebrate appendicular muscle formation. We propose that the adoption of the fully derived mode of hindlimb muscle formation from this bimodal character state is an evolutionary innovation that was critical to the success of the tetrapod transition.

    Abstract Introduction: The training of the pelvic floor muscles is widely used for treating pelvic floor dysfunctions, like urinary incontinence. During the training, abdominal contractions are avoided; however several studies support the use of the synergy between these muscle groups. Objective: Carrying out a systematic review of studies that seek to identify the presence of synergy between the muscles of the abdomen and the pelvic floor and its functionality in women without pelvic flo...

  20. Modelling the pelvic floor for investigating difficulties during childbirth (United States)

    Li, Xinshan; Kruger, Jennifer A.; Chung, Jae-Hoon; Nash, Martyn P.; Nielsen, Poul M. F.


    Research has suggested that athletes involved in high-intensity sports for sustained periods have a higher probability of experiencing prolonged second stage of labour compared to non-athletes. The mechanism responsible for this complication is unknown but may depend on the relative size or tone of the pelvic floor muscles. Prolonged training can result in enlargement and stiffening of these muscles, providing increased resistance as the fetal head descends through the birth canal during a vaginal birth. On the other hand, recent studies have suggested an association between increased muscle bulk in athletes and higher distensibility. This project aims to use mathematical modelling to study the relationship between the size and tone of the pelvic floor muscles and the level of difficulty during childbirth. We obtained sets of magnetic resonance (MR) images of the pelvic floor region for a female athlete and a female non-athlete. Thirteen components of the pelvic floor were segmented and used to generate finite element (FE) models. The fetal head data was obtained by laser scanning a skull replica and a FE model was fitted to these data. We used contact mechanics to simulate the motion of the fetal head moving through the pelvic floor, constructed from the non-athlete data. A maximum stretch ratio of 3.2 was induced in the muscle at the left lateral attachment point to the pubis. We plan to further improve our modelling framework to include active muscle contraction and fetal head rotations in order to address the hypotheses that there is a correlation between the level of difficulty and the size or tone of the pelvic floor muscles.
