We review and describe the neuroradiological presentation and long-term outcomes in patients with meningocele manque. From April 1983 through March 2005, 15 children (7 boys and 8 girls) aged 12 days to 1 year underwent surgical exploration for suspected occult spinal dysraphism and were found to have manifestations of meningocele manque and other anomalies. All patients had cutaneous manifestations (small skin defect, hemangioma and human tails). No patient had abnormal neurological or urological findings other than skin stigmata. Spinal ultrasonography or MRI performed preoperatively showed low-lying spinal conus, intrathecal dorsal bands or subcutaneous tracts. These bands were confirmed at surgery in all patients. Histology and immunohistochemistry of these bands shows peripheral nerves, ganglions, collagen fibers, muscle fibers and small vessels. These findings suggested that these bands had hamartomatous origins. Sectioning of dorsal tethering bands of meningocele manque had good long-term results. These dorsal tethering bands should be sought in the evaluation of patients with occult spinal dysraphism and surgically transected. (author)

Sacral agenesis (or caudal regression syndrome) is a rare congenital anomaly involving various levels of coccygeal, sacral, and even lumbar or lower thoracic vertebral dysgenesis, as well as spinal cord abnormalities. A few cases have been previously reported in Korea, especially based upon MRI findings. We describe a case of a 4-year-old girl with partially bilateral agenesis of the sacrum (type II), and club-shaped (chisel-shaped) spinal cord disruption. We also review MRI findings of sacral agenesis, focused on classification and radiological findings.

Epithelioid hemangioendothelioma (EHE) is a rare vascular soft-tissue tumour of intermediate malignancy. Neurofibromatosis type I (NF-1) is a genetic syndrome associated with soft tissue sarcoma and higher risk of developing neoplasia. Lateral meningoceles are uncommon entities, being mostly associated with NF-1. We report a case of a 31-year-old woman, with NF-1 and past history of right thalamic/peduncular astrocytoma WHO grade II, admitted to the Neurosurgery Department in December 2003 due to severe low back pain, irradiating to the left leg without a radicular pattern. Thoraco-lumbar magnetic resonance imaging (MRI) showed a large left posterior paravertebral expansive lesion, bilateral and multiple thoraco-lumbar lateral meningoceles and dural ectasias with scalloping of the vertebral bodies. Biopsy of the paravertebral mass lesion disclosed EHE. We present this case because of the novel association between NF-1 and EHE, and the unusual aggressiveness of the neoplasia. Additionally, we highlight the co-existence of bilateral and multiple lateral meningoceles. (orig.)

Herpes zoster is caused by the infection of Varicella-Zoster virus. The anatomical distribution of herpes zoster in the sacral area is only 6. 9%1). Moreover, the onset rate of herpes zoster with urinary dysfunction is 0.6%1). The lesion sites of herpes zoster which cause urinary dysfunction are almost lumber and sacral areas. We describe four cases of sacral herpes zoster with urinary dysfunction in this report. All patients were elderly people (66-84 years old), and all patients were administered anti-virus drugs and alpha 1-adrenergic receptor blockers. Because of urinary retention, three patients have performed clean intermittent self-catheterization (CIC) for several weeks. As the lesions of herpes zoster healed, each patient recovered from urinary dysfunction.

2013-01-01

Low back pain (LBP) and hip pain frequently occur during pregnancy and postpartum period. Although pelvic and mechanic lesions of the soft tissues are most responsible for the etiology, sacral fracture is also one of the rare causes. A 32-year-old primigravid patient presented with LBP and right hip pain which started 3 days after vaginal delivery. Although direct radiographic examination was normal, magnetic resonance imaging of the sacrum revealed sacral stress fracture. Lumbar spine and femoral bone mineral density showed osteoporosis as a risk factor. There were no other risk factors such as trauma, excessive weight gain, and strenuous physical activity. It is considered that the patient had sacral fatigue and insufficiency fracture in intrapartum period. The patient's symptoms subsided in 3 months after physical therapy and rest. In conclusion, sacral fractures during pregnancy and postpartum period, especially resulting from childbirth, are very rare. To date, there are two cases in the literature. In cases who even do not have risk factors related to vaginal delivery such as high birth weight infant and the use of forceps, exc., sacral fracture should be considered in the differential diagnosis of LBP and hip pain started soon after child birth. Pregnancy-related osteoporosis may lead to fracture during vaginal delivery.

Landmarks for Sacral Debridement in Sacral Pressure Sores.

Choo, Joshua H; Wilhelmi, Bradon J

2016-03-01

Most cases of sacral osteomyelitis arising in the setting of sacral pressure ulcers require minimal cortical debridement. When faced with advanced bony involvement, the surgeon is often unclear about how much can safely be resected. Unfamiliarity with sacral anatomy can lead to concerns of inadvertent entry into the dural space and compromise of future flap options. A cadaveric study (n = 6), in which a wide posterior dissection of the sacrum, was performed. Relationships of the dural sac to bony landmarks of the posterior pelvis were noted. The termination of the dural sac was found in our study to occur at the junction of S2/S3 vertebral bodies, which was located at a mean distance of 0.38 ± 0.16 cm distal to the inferior-most extent of the posterior superior iliac spine (PSIS). The mean thickness of the posterior table of sacrum at this level was 1.7 cm at the midline and 0.5 cm at the sacral foramina. The PSIS is a reliable landmark for localizing the S2/S3 junction and the termination of the dural sac. Sacral debridement medial to the sacral foramina above the level of PSIS must be conservative whenever possible. If aggressive debridement is necessary above this level, the surgeon must be alert to the possibility of dural involvement.

2014-03-01

Full Text Available Primary sacral tumours are rare, therefore experience of managing their associated complications are very limited. Effective surgical treatment of pelvic chondrosarcoma remains a major challenge for orthopaedic surgeons, due to the complex anatomic structure of the pelvis, the lack of defined compartment borders, the close vicinity to vital structures, and the risk of jeopardizing pelvic structural stability. We report a rare case of a giant sacral chondrosarcoma (100cm x 80cm in an elderly male who successfully underwent tumour resection with good functional outcome and recovery. Long term follow up is essential in view of the possibility of local tumour recurrence.

Full Text Available Spontaneous sphenoid sinus lateral wall meningoceles are rare lesions with an unknown etiology. Endoscopic endonasal technique is a considerable route in the treatment of this condition. The aim of this paper is to report the etiology, surgical technique, and outcome in a patient repaired via endoscopic endonasal approach. A 51-year-old male patient applied with rhinorrhea started three months ago after an upper respiratory infection. There were no history of trauma or sinus operation. Biochemical analysis of the fluid was positive for beta-2-transferrin. This asypthomatic patient had undergone for repairment of lateral sphenoid sinus meningocele with endoscopic endonasal transsphenoidal approach. After endoscopic endonasal meningocele closure procedure no complications occured and a quick recovery was observed. Endoscopic endonasal approach is an effective and safe treatment modality of spontaneous lateral sphenoid sinus meningoceles and efficient in anterior skull base reconstruction.

Full Text Available Liquoric fistula (LF is defined as the communication of the subarachnoid space with the external environment, which main complication is the development of infection in the central nervous system. We reported the case of a patient with non-traumatic eyelid liquoric fistula secondary to orbital meningocele (congenital lesion, which main clinical manifestation was unilateral eyelid edema. Her symptoms and clinical signs appeared in adulthood, which is uncommon. The patient received surgical treatment, with complete resolution of the eyelid swelling. In conclusion, eyelid cerebrospinal fluid (CSF fistula is a rare condition but with great potential deleterious to the patient. It should be considered in the differential diagnosis of unilateral eyelid edema, and surgical treatment is almost always mandatory.

total of 38 centering. Eight patients underwent the PNE procedure on both the S3 foramina. The sacral foramen was centred at the first attempt in 36 out of 38 cases. Two cases required several attempts to centre correctly the foramen. In 4 patients out of 30 a second electrode was implanted. In one patient who had a non consolidated sacral fracture, CT guidance enabled insertion of the electrode inside the only practicable foramen, a manoeuvre that would have been impossible with fluoroscopic guidance. Only once was repositioned after a CT control. During the whole trial period we had a positive response to the PNE test in 18 out of 30 patients (60%), a partial response in 4 out of 30 patients and a negative response in the remaining 8 patients. None of the patients who underwent the PNE test had infectious complications and the procedure was well tolerated by all. The procedure lasted about 45 minutes. Conclusions: The PNE test under Ct guidance proved to be more efficient compared with the traditional technique as the direct view of the electrode position helped to define with greater reliability the patients who were non-responsive to sacral stimulation. Moreover, this method was particularly efficient in patients with sacral anomalies where the traditional guide might fail. The operators' reduced exposure to radiation is an advantage to be taken into consideration. Finally, the usage of mobile CT apparatus in an operating theatre can improve the technique for permanent implantations [it

INTRODUCTION: Sacral neuromodulation (SNM) (sacral nerve stimulation SNS) has become an established therapy for functional disorders of the pelvic organs. Despite its overall success, the therapy fails in a proportion of patients. This may be partially due to inadequate electrode placement...... with suboptimal coupling of the electrode and nerve. Based on these assumptions the technique of sacral spinal neuromodulation has been redefined.

2016-01-01

Full Text Available While 22 articles have reported on sacral stress fractures, it is a rare injury and its etiology is not well known. We present the case of a 16-year-old male who presented with low back pain in 2015. He was a high school soccer player with a previous history of a bilateral L5 lumbar spondylolysis in 2014. The patient refrained from soccer and wore a brace for six months. Two months after restarting soccer, he again complained of low back pain. After 1 year, a lumbar spine computed tomography revealed the bone union of the spondylolysis. At his first visit to our hospital, his general and neurological conditions were normal and laboratory data were within the normal range. Sacral coronal magnetic resonance imaging (MRI of the left sacral ala revealed an oblique lineal signal void surrounding bone marrow edema. Based on his symptoms, sports history, and MRI, he was diagnosed with a sacral stress fracture. He again refrained from soccer; his low back pain soon improved, and, after 1 year, the abnormal signal change had disappeared on sacral MRI. Recurrent low back pain case caused by a sacral stress fracture occurring after the bone union of lumbar spondylolysis is uncommon.

Ipsilateral Hip Dysplasia in Patients with Sacral Hemiagenesis: A Report of Two Cases

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available Sacral agenesis (SA is a rare condition consisting of the imperfect development of any part of the sacrum. This paper describes two cases of the rare cooccurrence of ipsilateral SA and developmental dysplasia of the hip (DDH and analyzes possible contributory factors for SA and DDH. Each of a 16-year-old female and 13-year-old female visited our hospital for left hip pain and limping. The findings of physical examinations showed a lower limb length discrepancy (left side in both cases, as well as left hip pain without limitations of the range of motion or neurological deficits. Initial radiographs demonstrated left subluxation of the left hip with associated acetabular dysplasia and partial left sacral agenesis. MRI revealed a tethering cord with a fatty filum terminale, and periacetabular osteotomy combined with allogeneic bone grafting was performed. After the surgery, the patients experienced no further pain, with no leg length discrepancy and were able to walk without a limp, being neurologically normal with a normal left hip range of motion. The cooccurrence of SA and DDH suggests a plausible hypothesis to explain the embryogenic relationship between malformation of the sacrum and hip.

A rare case of lumbo-sacral lipoma in an adult case is reported. A 55-year-old male was admitted to the Department of Neurosurgery, Mazda Hospital, after a history of one year of urinary incontinence. Neurologically, no motor or sensory disturbance of the lower extremities was found in this patient. MRI showed a mass with high signal intensity on T2-weighted image, located between L3 to S2 vertebral segments. Metrizamide-CT scan demonstrated the outline of this hypodense mass at the same location as shown on MRI image. A L3 through L5 laminectomy was performed and the tumor was subtotally removed. Microscopic examination revealed that the tumor mass was made up of mature lipoma cells. Postoperative course of the patient was uneventful. The urinary incontinence was improved slightly. No motor or sensory deficit was found. We thought that MRI was useful for the correct diagnosis of lumbosacral lipoma. And it is best managed by operative removal of the tumor as early as possible after it is diagnosed.

2009-01-01

Objective: To discuss the management and feasibility of sacral block anesthesia in pediatric interventional therapy. Methods: A total of 80 pediatric patients were randomly and equally divided into two groups. Patients in group A received sacral block anesthesia together with basic anesthesia with propofol, while patients in group B received intravenous anesthesia with propofol. Small amount of ketamine as maintaining dose was used in both groups when needed. Results: The interventional management was successfully completed in all patients. A marked decrease in blood pressure occurred in three patients of group A receiving sacral block anesthesia. In group B receiving intravenous anesthesia, a decrease of SpO 2 to below 90 percent was seen in 8 cases, and obvious bradycardia developed in 12 cases. All these patients were treated with intravenous medication or by reducing the dose of propofol. Additional small dose of ketamine was needed in 4 patients during the procedure. Conclusion: Sacral block anesthesia combined with intravenous anesthesia is one of the effective anesthesia management schemes for pediatric interventional therapy. (authors)

The various pathologic conditions detected at CT and MRI and subsumed by the term 'sacral tumor' include primary bone tumors, sacral canal tumors and metastases. Among these, metastases are much more common than primary bone tumors, of which chordoma is the most common. Although the imaging findings of sacral tumors are nonspecific, a patient's age and sex, and specific findings such as calcification or fluid-fluid levels, can help radiologists in their differential diagnosis. We describe the imaging findings of primary sacral tumors, emphasizing the MRI findings

The purpose of this study is to evaluate the correlation between sacral fractures and neurological deficits as complications. From November 2002 to February 2005, 12 patients (15 fractures) were found to have sacral fractures without other spinal injuries or brain injuries and were evaluated by plain CT scans immediately after trauma. This group included 6 males and 6 females, whose age ranged from 17 to 67 years with mean of 39.9±17.4. All patients were classified according to AO (Arbeitsgemeinschaft fuer Osteosynthesefragen) classification (pelvic ring fracture) and Denis's classification. Displacements of sacral fractures were evaluated by plain CT scans for all patients. We defined displacements using the key slice in CT scans that included the first foramen in the sacrum. Five cases, including 2 with bi-lateral sacral fractures, were complicated with neurological deficits. There was one case with a neurological deficit of 7 Type B fractures (14%) and 4 cases with neurological deficits of 5 Type C fractures (80%) in the AO classification. There were 6 fractures with neurological deficits of 12 Zone II fractures (50%) and one fracture with neurological deficits of one Zone III fractures (100%) in Denis's classification. There was a significant correlation between the extent in the displacement of the sacral fractures and neurological deficits. For more than 3 mm displacements in the medial or lateral or anterior directions, neurological deficits increased significantly. In emergency medicine, it is difficult to evaluate the neurological findings of patients with impaired consciousness. Our evaluation using CT scan is valuable as a predictor of neurological deficits and for an optimal reduction in sacral fractures in patients with in impaired consciousness. (author)

Sacral bed sores still present a serious problem in most surgery departments. They occur mainly in elderly patients of limited mobility. The treatment of such sores extends over long periods of time and therefore involves considerable costs. The material consisted of 11 sacral pressure ulcers treated surgically. The sores occurred in 4 severely disabled patients suffering from proximal third femur fractures, 4 patients with traumatic brain injury (treated in the Intensive Care Unit), and 3 patients suffering from bed sores after spinal cord injury. In 6 patients a fasciocutaneous flap was applied to the sores and in 5 cases a pedicled musculocutaneous gluteus maximus flap. The end results were assessed using Seiler's criteria. Complications of the "seroma" type were observed in 3 patients, and in 2 marginal necrosis. In all our patients complete healing was achieved within 2-4 weeks. On analysing our experience to date in surgical treatment of bed sores we are of the opinion that even extensive sacral sores can be covered with unilateral pedicled flaps provided that they are appropriately planned. Deep sores of the 4th degree sometimes with concomitant osteomyelitis require pedicled muscle flaps or in some cases musculocutaneous flaps to improve local circulation. The preparation of the patient for reconstruction surgery is just as important as the operation itself and therefore such preparation should never be neglected.

We report an unusual case of Ewing's sarcoma / primitive neuroectodermal tumor (PNET) of the sacral nerve plexus in a 9-year-old boy who presented with a soft tissue swelling and severe piercing pain in the lower back region. MRI of the lumbosacral spine showed a lobulated soft tissue mass with clubbed finger-like projections along the path of the sacral nerves, which had caused widening of the spinal canal and the sacral foramina (S2–S4 level). There was presacral extension and posterior scalloping of the sacral vertebrae. Histopathology of the lesion confirmed Ewing's sarcoma / PNET of the sacral spinal nerve plexus. The patient responded favorably to chemotherapy and radiotherapy, showing clinical and radiological improvement

Retention of urine and sacral paraesthesia in anogenital herpes simplex infection.

Edis, R H

1981-01-01

Two definite and 2 probable cases of anogenital herpes simplex and sacral radiculitis are described. Symptoms were typical and consisted of paraesthesia and neuralgic pain in the perineum and legs, urinary retention and constipation occurring within several days to a week after an anogenital herpetic eruption. However, at presentation only 1 case had an obvious history of anogenital herpes simplex. Neurological signs were not striking and consisted of a reduced appreciation of light touch and pin prick over the sacral dermatomes and in 2 cases reduced anal sphincter tone. CSF examination in 3 patients showed a lymphocytosis. Bladder catheterisation was required for up to 2 weeks in 2 patients. The paraesthesia persisted for weeks to months. It should be more widely recognised that anogenital herpes simplex, with sacral radiculitis, is probably the commonest cause of acute retention of urine in young sexually active people.

Objective: To analyze the effective of preserving sacral nerve root during surgical treatment of sacral chordoma. Methods: This retrospective study included 30 cases of sacral chordomas. All the cases were operated with posterior approach. The blood loss and blood transfusion during operation, the drainged blood after operation were reviewed. The sphincter muscle function of bladder and bowl were observed. Results: Tremendous reduction of blood loss during surgery was found in all cases, the blood loss was 1280 ml in average, the blood transfusion was 1080 ml in average, the drainged blood after ope-ration was 650 ml. Nine patients whose sacral nerve roots had been reserved bilaterally at and above S 3 level, the sphincter muscle function of bladder and bowl was good, whereas the function of sphincter muscle impaired in the other 21 patients and in one case colostomy and ureterocutaneostomy were used. Conclusion: Preoperative arterial embolization is effective method and can lead to excellent results. Even if the tumor is relatively huge and the upper resection margin is as high as at S 1 or S 2 level, the tumor can be removed successfully by posterior approach. Sacral nerve should be preserved as possible. (authors)

Full Text Available Background: Resection of sacral chordomas is challenging. The anatomy is complex, and there are often no bony landmarks to guide the resection. Achieving adequate surgical margins is, therefore, difficult, and the recurrence rate is high. Use of computer navigation may allow optimal preoperative planning and improve precision in tumor resection. The purpose of this study was to evaluate the safety and feasibility of computer navigation-aided resection of sacral chordomas. Methods: Between 2007 and 2013, a total of 26 patients with sacral chordoma underwent computer navigation-aided surgery were included and followed for a minimum of 18 months. There were 21 primary cases and 5 recurrent cases, with a mean age of 55.8 years old (range: 35-84 years old. Tumors were located above the level of the S3 neural foramen in 23 patients and below the level of the S3 neural foramen in 3 patients. Three-dimensional images were reconstructed with a computed tomography-based navigation system combined with the magnetic resonance images using the navigation software. Tumors were resected via a posterior approach assisted by the computer navigation. Mean follow-up was 38.6 months (range: 18-84 months. Results: Mean operative time was 307 min. Mean intraoperative blood loss was 3065 ml. For computer navigation, the mean registration deviation during surgery was 1.7 mm. There were 18 wide resections, 4 marginal resections, and 4 intralesional resections. All patients were alive at the final follow-up, with 2 (7.7% exhibiting tumor recurrence. The other 24 patients were tumor-free. The mean Musculoskeletal Tumor Society Score was 27.3 (range: 19-30. Conclusions: Computer-assisted navigation can be safely applied to the resection of the sacral chordomas, allowing execution of preoperative plans, and achieving good oncological outcomes. Nevertheless, this needs to be accomplished by surgeons with adequate experience and skill.

Minimally invasive sacral colpopexy has increased over the past decade, with many senior physicians adopting this new skill set. However, skill acquisition at an academic institution in the presence of postgraduate learners is not well described. This manuscript outlines the introduction of laparoscopic sacral colpopexy to an academic urogynecology service that was not performing minimally invasive sacral colpopexies, and it also defines a surgical learning curve. The first 180 laparoscopic sacral colpopexies done by four attending urogynecologists from January 2009 to December 2011 were retrospectively analyzed. The primary outcome was operative time. Secondary outcomes included conversion to laparotomy, estimated blood loss, and intra- and postoperative complications. Linear regression was used to analyze trends in operative times. Fisher's exact test compared surgical complications and counts of categorical variables. Mean total operative time was 250 ± 52 min (range 146-452) with hysterectomy and 222 ± 45 (range 146-353) for sacral colpopexy alone. When compared with the first ten cases performed by each surgeon, operative times in subsequent groups decreased significantly, with a 6-16.3% reduction in overall times. There was no significant difference in the rate of overall complications regardless of the number of prior procedures performed (p = 0.262). Introduction of laparoscopic sacral colpopexy in a training program is safe and efficient. Reduction in operative time is similar to published learning curves in teaching and nonteaching settings. Introducing this technique does not add additional surgical risk as these skills are acquired.

Full Text Available The objective of this study was to describe our experience using sacral neuromodulation to treat urinary urgency, frequency, urge incontinence, and chronic urinary retention in patients with cardiac pacemakers. With the increasingly widespread use of InterStim for bladder function restoration, we are seeing more complex patients with multiple comorbidities, including cardiac conditions. Herein, we report 3 cases of individuals with cardiac pacemakers who underwent InterStim implantation to treat urinary conditions. This study is a case series of 3 patients with cardiac pacemakers who underwent sacral neuromodulation to treat refractory voiding dysfunction. The initial patient screening for InterStim therapy involved percutaneous nerve evaluation (PNE, in which a temporary untined lead wire was placed through the S3 foramen. Patients who did not respond to PNE proceeded to a staged implant. All patients in this study had a greater than 50% improvement of their urinary symptoms during the initial trial and underwent placement of the InterStim implantable pulse generator (IPG. Postoperative programming was done under electrocardiogram monitoring by a cardiologist. No interference was observed between the Inter-Stim IPG and the cardiac pacemaker. In this group of patients, sacral neuromodulation in the presence of a cardiac pacemaker appears to have been safe.

Sacral colpopexy may be complicated by mesh exposure, and the surgical treatment of mesh exposure typically results in minor postoperative morbidity and few delayed complications. A 75-year-old woman presented 7 years after a laparoscopic sacral colpopexy, with Mersilene mesh, with an apical mesh exposure. She underwent an uncomplicated transvaginal excision and was asymptomatic until 8 months later when she presented with vaginal drainage and a sacral abscess. This was successfully treated with laparoscopic enterolysis, drainage of the abscess, and explantation of the remaining mesh. Incomplete excision of exposed colpopexy mesh can lead to ascending infection and sacral abscess. Laparoscopic drainage and mesh removal may be considered in these patients.

This report describes the case of a 55-year-old woman with varicella-zoster virus (VZV) sacral meningoradiculitis (Elsberg syndrome) who presented with herpes zoster in the left S2 dermatome area, urinary retention, and constipation. Lumbar magnetic resonance imaging showed the left sacral nerve root swelling with enhancement. Thereafter, she suddenly showed massive hematochezia and hemorrhagic shock because of a rectal ulcer. To elucidate the relation between Elsberg syndrome and rectal ulcer, accumulation of similar cases is necessary. To avoid severe complications, attention must be devoted to the possibility of rectal bleeding in the early stage of Elsberg syndrome.

Storytelling: Performance, Presentations and Sacral Communication

Full Text Available Various schools of tale research manifested the relationship of tales of the sacred based on their ideological preconceptions: the relationship between tales and the sacred is refused or accepted. In this article tales are investigated not from the perspective of the possible sacral referent(s but rather it looks at them as a kind of communicational subsystem that is part of human culture. The focus is on revealing the specific features of sacral communication in the communication system of tales. Sacral communication is a special form of communication in which the elements of the communication model are transformed. The goal of sacral communication is exactly this kind of identity creation. This may be oriented towards creating a personal or a communal self-identity. Among its characteristics we may find the special type of language forms in which the predominance of linguistic elements pushes the sense conveying possibilities more into the background than usual, and those linguistic forms that restructure consciousness become emphasized. In this communication the tale telling is transformed by a language use characteristic of sacral communication (rhythm, repetition and rhetorical forms. Various examples explain that traditional tale telling creates a complex effect related to the visual, auditory, and kinetic senses: a modification and transformation of the self-understanding and self-identity that connect the world of tale telling to sacral communication.

2015-01-01

Full Text Available Chordomas are known as rare primary malign tumours that have formed from primitive notochord remains. Sacral chordomas grow slowly but locally and aggressively. Chordomas are locally invasive and have low tendency to metastasis and have a poor prognosis in long-term follow-up. Metastasis may be seen in a rate of 5–40% of the chordomas. Metastasis of chordomas is common in liver, lung, lymph nodes, peritoneum, and brain. The treatment approaches, including surgery, have been discussed in the literature before. Susceptibility to radiotherapy and chemotherapy is controversial in these tumours. The success of surgical treatment affects survival directly. In this report, we will report a sacral chordoma case in which an intraperitoneal distant metastasis occurred and discuss the surgical approach.

Sacral Stress Fracture in an Amateur Badminton Player

Full Text Available Sacral stress fractures are rare among athletes but have been reported most frequently in long distance runners. We report herein the first case of a sacral stress fracture in an amateur badminton player. A 16-year-old, left-handed adolescent girl, who had just started to play badminton 3 months previously, complained of acute left buttock pain when she received a shuttlecock. Magnetic resonance imaging revealed a linear lesion of the left sacrum with low signal intensity on T1- and high signal intensity on T2-weighted images, which was consistent with a stress fracture. Conservative treatment with rest relieved her symptoms. Her fracture was considered to have occurred due to repetition of an exercise that caused excessive vertical power.

Surgical techniques for lumbo-sacral fusion.

Tropiano, P; Giorgi, H; Faure, A; Blondel, B

2017-02-01

Lumbo-sacral (L5-S1) fusion is a widely performed procedure that has become the reference standard treatment for refractory low back pain. L5-S1 is a complex transition zone between the mobile lordotic distal lumbar spine and the fixed sacral region. The goal is to immobilise the lumbo-sacral junction in order to relieve pain originating from this site. Apart from achieving inter-vertebral fusion, the main challenge lies in the preoperative determination of the fixed L5-S1 position that will be optimal for the patient. Many lumbo-sacral fusion techniques are available. Stabilisation can be achieved using various methods. An anterior, posterior, or combined approach may be used. Recently developed minimally invasive techniques are gaining in popularity based on their good clinical outcomes and high fusion rates. The objective of this conference is to resolve the main issues faced by spinal surgeons in their everyday practice. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Little is known about outcomes of sacral neuromodulation in the general community, with published reports to date limited to case series or randomized, controlled trials. The goal of this analysis was to identify the national sacral neuromodulation test phase success rate and patient factors that contribute to success. Medical claims data were obtained from a 5% sample of Medicare beneficiaries (1997 to 2007) and from employees of 25 large (Fortune 500) companies (Ingenix®, 2002 to 2007). Using billing codes for the sacral neuromodulation procedure, success was defined as progressing from test phase (percutaneous or staged) to battery implantation. The rate of success was compared based on age, race, gender and diagnosis. In the Medicare sample 358 patients received percutaneous test stimulation and 1,132 underwent 2-stage lead placement, of whom 45.8% and 35.4%, respectively, underwent subsequent battery implantation. In the privately insured sample there were 266 percutaneous procedures and 794, 2-stage procedures. Percutaneous procedures were followed by battery placement in 24.1% of cases, whereas 50.9% of staged procedures resulted in battery implantation. Gender was the only consistent predictor of success, with female patients demonstrating higher success rates in each data set. The sacral neuromodulation success rates in these data sets are inferior to those published in case series and small randomized, controlled trials. Women had significantly better results than men and privately insured individuals had better results than those with Medicare, indicating a potential age effect.

2004-02-01

Herpetic genital infection is a common sexually transmitted disease, caused in most cases by type 2 Herpes simplex virus (HSV2). This virus is characterized by its neurotropic properties and its ability to establish latency in sacral sensory ganglions. Some cases of genital primo-infection are complicated by viral replication dissemination to neigbhoring nerve structures like meninges and radicular terminations. In such cases muco-cutaneous manifestations are associated with peripheral neurological impairment in the form of meningo-radiculitis. Physicians should be familiar with these neurological symptoms knowing that they always regress completely. The present report illustrates these complications and reviews the potential neurological implications described in the literature.

The defects of the spinal cord enclose diverse malformations that go from spina bifida to myelomeningocele but there is also a rare variant that is the intercalary bone. The incidence of this phenomenon may vary in 1 to 1,000 to 5,000. At our knowledge, there are no cases reported where it can be an association of intercalary bone and a bifid spine in different levels. In this article we report the case of one patient that coincide with an intercalary cervical bone, bifid spine in lumbar column and bifid spine in sacral column. The objective of this article is also to comment how the clinical symptoms are unspecific, the chronic pain is the frequent symptom, and how the physiotherapy and anti-inflammatory drugs can provide excellent results in a short and medium term.

Schildhauer Thomas A

2008-11-01

Full Text Available Abstract Background Primary sacral tumors are rare and experience related to accompanying effects of these tumors is therefore limited to observations on a small number of patients. Case presentation In this case report we present a patient with a history of primary sacral chondrosarcoma, an infection of an implanted spinal stabilization device and discuss the challenges that resulted from a colonic fistula associated with large, life threatening abscesses as late complications of radiotherapy. Conclusion In patients with sacral tumors enterocutaneous fistulas after free musculotaneous free flaps transfer are rare and can occur in the setting of surgical damage followed by radiotherapy or advanced disease. They are associated with prolonged morbidity and high mortality. Identification of high-risk patients and management of fistulas at an early stage may delay the need for subsequent therapy and decrease morbidity.

Full Text Available Fetuses with neural tube defects (NTDs maybe associated with syndromes, disorders, and maternal risk factors. This article provides a comprehensive review of syndromes, disorders, and maternal risk factors associated with NTDs, such as Currarino syndrome, sacral defect with anterior meningocele, Jarcho-Levin syndrome (spondylo-costal dysostosis, lateral meningocele syndrome, neurofibromatosis type I, Marfan syndrome, and hyperthermia. The recurrence risk and the preventive effect of maternal folic acid intake in NTDs associated with syndromes, disorders, and maternal risk factors may be different from those of non-syndromic multifactorial NTDs. Perinatal identification of NTDs should alert one to the syndromes, disorders, and maternal risk factors associated with NTDs, and prompt a thorough etiologic investigation and genetic counseling.

Sacral insufficiency fractures: an easily overlooked cause of back pain in the ED.

LENUS (Irish Health Repository)

Galbraith, John G

2011-03-01

Sacral insufficiency fractures are an important and treatable cause of severe back pain. Despite publication of several case reports since its original description in 1982, awareness of these injuries remains inadequate in emergency medicine. Most patients are elderly women presenting with intractable lower back pain. Postmenopausal osteoporosis is the most significant risk factor. Marked sacral tenderness is common. Neurologic impairment is rarely detectable. Routine radiography of the spine and pelvis is usually inconclusive. Computed tomography remains the diagnostic modality of choice. Treatment is usually conservative.

We report on the transabdominal resection of infected lumbosacral bone, synthetic mesh, and sinus tract following sacral colpopexy. A 45-year-old nulliparous patient who had undergone transvaginal mesh followed by robot-assisted sacral colpopexy presented with increasing back pain and foul-smelling vaginal drainage. An epidural abscess required surgical intervention, including diskectomy, sacral debridement, and mesh removal to drain the abscess and vaginal sinus tract. Recognized complications of open prolapse procedures also manifest following minimally invasive approaches. Osteomyelitis of the sacral promontory following sacral colpopexy may require gynecologic and neurosurgical management.

König, M A; Jehan, S; Boszczyk, A A; Boszczyk, B M

2012-05-01

U-shaped sacral fractures usually result from axial loading of the spine with simultaneous sacral pivoting due to a horizontal fracture which leads to a highly unstable spino-pelvic dissociation. Due to the rarity of these fractures, there is lack of an agreed treatment strategy. A thorough literature search was carried out to identify current treatment concepts. The studies were analysed for mechanism of injury, diagnostic imaging, associated injuries, type of surgery, follow-up times, complications, neurological, clinical and radiological outcome. Sixty-three cases were found in 12 articles. No Class I, II or III evidence was found in the literature. The most common mechanism of injury was a fall or jump from height. Pre-operative neurological deficit was noted in 50 (94.3%) out of 53 cases (not available in 10 patients). The most used surgical options were spino-pelvic fixation with or without decompression and ilio-sacral screws. Post-operative complications occurred in 24 (38.1%) patients. Average follow-up time was 18.6 months (range 2-34 months). Full neurological recovery was noted in 20 cases, partial recovery in 14 and 9 patients had no neurological recovery (5 patients were lost in follow-up). Fracture healing was mentioned in 7 articles with only 1 case of fracture reduction loss. From the current available data, an evidence based treatment strategy regarding outcome, neurological recovery or fracture healing could not be identified. Limited access and minimal-invasive surgery focussing on sacral reduction and restoration seems to offer comparable results to large spino-pelvic constructs with fewer complications and should be considered as the method of choice. If the fracture is highly unstable and displaced, spino-pelvic fixation might offer better stability.

Parasacral Perforator Flaps for Reconstruction of Sacral Pressure Sores.

Despite advances in reconstruction techniques, pressure sores continue to present a challenge to the plastic surgeon. The parasacral perforator flap is a reliable flap that preserves the entire contralateral side as a future donor site. On the ipsilateral side, the gluteal muscle itself is preserved and all flaps based on the inferior gluteal artery are still possible. We present our experience of using parasacral perforator flaps in reconstructing sacral defects. Between August 2004 and January 2013, 19 patients with sacral defects were included in this study. All the patients had undergone surgical reconstruction of sacral defects with a parasacral perforator flap. The patients' sex, age, cause of sacral defect, flap size, flap type, numbers of perforators used, rotation angle, postoperative complications, and hospital stay were recorded. There were 19 parasacral perforator flaps in this series. All flaps survived uneventfully except for 1 parasacral perforator flap, which failed because of methicillin-resistant Staphylococcus aureus infection. The overall flap survival rate was 95% (18/19). The mean follow-up period was 17.3 months (range, 2-24 months). The average length of hospital stay was 20.7 days (range, 9-48 days). No flap surgery-related mortality was found. Also, there was no recurrence of sacral pressure sores or infected pilonidal cysts during the follow-up period. Perforator-based flaps have become popular in modern reconstructive surgery because of low donor-site morbidity and good preservation of muscle. Parasacral perforator flaps are durable and reliable in reconstructing sacral defects. We recommend the parasacral perforator flap as a good choice for reconstructing sacral defects.

Sacral Variability in Tailless Species: Homo sapiens and Ochotona princeps.

Tague, Robert G

2017-05-01

Homo sapiens is variable in number of sacral vertebrae, and this variability can lead to obstetrical complication. This study uses the comparative method to test the hypothesis that sacral variability in H. sapiens is associated with absence of a tail. Three species of lagomorphs are studied: Ochotona princeps (N = 271), which is tailless, and Lepus californicus (N = 212) and Sylvilagus audubonii (N = 206), which have tails. Results show that O. princeps has (1) higher diversity index for number of sacral vertebrae (0.49) compared to L. californicus (0.25) and S. audubonii (0.26) and (2) significantly higher percentage of individuals with the species-specific nonmodal number of sacral vertebrae (43.9%) compared to L. californicus (14.2%) and S. audubonii (15.5%). Comparison of H. sapiens (N = 1,030; individuals of age 20-39 years) with O. princeps shows similarities between the species in diversity index (also 0.49 in H. sapiens) and percentage of individuals with nonmodal number of sacral vertebrae (37.3% in H. sapiens). Homeotic transformation best explains the results. H. sapiens and O. princeps show propensity for caudal shift at the sacral-caudal border (i.e., homeotic transformation of the first caudal vertebra to a sacral vertebra). Caudal and cranial shift among presacral vertebrae increases or decreases this propensity, respectively. Increase in number of sacral vertebrae in H. sapiens by homeotic transformation reduces pelvic outlet capacity and can be obstetrically hazardous.

Chen, Yen-Chou; Huang, Eng-Yen; Lin, Pao-Yuan

2014-03-01

The gluteus maximus myocutaneous flap was considered the workhorse that reconstructed sacral pressure sores, but was gradually replaced by fasciocutaneous flap because of several disadvantages. With the advent of the perforator flap technique, gluteal perforator (GP) flap has gained popularity nowadays. The aim of this study was to compare the complications and outcomes between GP flaps and gluteal fasciocutaneous rotation (FR) flaps in the treatment of sacral pressure sores. Between April 2007 and June 2012, 63 patients underwent sacral pressure sore reconstructions, with a GP flap used in 31 cases and an FR flap used in 32 cases. Data collected on the patients included patient age, gender, co-morbidity for being bedridden and follow-up time. Surgical details collected included the defect size, operative time and estimated blood loss. Complications recorded included re-operation, dehiscence, flap necrosis, wound infection, sinus formation, donor-site morbidity and recurrence. The complications and clinical outcomes were compared between these two groups. We found that there was no significant difference in patient demographics, surgical complications and recurrence between these two groups. In gluteal FR flap group, all recurrent cases (five) were treated by reuse of previous flaps. Both methods are comparable, good and safe in treating sacral pressure sores. Gluteal FR flap can be performed without microsurgical dissection, and re-rotation is feasible in recurrent cases. The authors suggest using gluteal FR flaps in patients with a high risk of sore recurrence. Copyright © 2013 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Bilateral chronic sacral neuromodulation for treatment of lower urinary tract dysfunction.

Science.gov (United States)

Hohenfellner, M; Schultz-Lampel, D; Dahms, S; Matzel, K; Thüroff, J W

1998-09-01

Chronic sacral neuromodulation aims at functional restoration of selected forms of nonneurogenic and neurogenic bladder dysfunction. The original technique, as described by Tanagho and Schmidt, provides unilateral sacral nerve stimulation via an implanted stimulator powering an electrode inserted into a sacral foramen. Its drawback was that the implant failed unpredictably in some patients despite previous successful percutaneous test stimulation. Therefore, we modified the stimulation technique to improve the efficacy of chronic sacral neuromodulation. Guarded bipolar electrodes powered by an implantable neurostimulator were attached bilaterally directly to the S3 nerves through a sacral laminectomy in 9 women and 2 men (mean age 43.4 years). Of the patients 5 had urinary incontinence due to detrusor hyperactivity and 6 had urinary retention from detrusor hypocontractility. Mean followup with repeated urodynamics was 13 months (range 9 to 28). Four significant complications were encountered in 4 patients. In 10 patients the urological sequelae of the neurological disorder were alleviated significantly (50% or more), including 5 who experienced complete relief of symptoms. The efficacy of chronic sacral neuromodulation can be improved by bilateral attachment of electrodes directly to the sacral nerves.

Sacral insufficiency fractures pose a diagnostic problem because of the nonspecific clinical signs and the absence of distinguishing features in standard radiological studies. The main causes are osteoporosis, making women reaching the age of menopause among the populations most commonly affected, and a history of radiotherapy, leading to the inclusion of neoplastic disease in the differential diagnosis. The characteristic site is ala sacralis, usually bilateral, and the fracture is vertical, running parallel to the sacroiliac joints. The sacral bone may also be involved (H pattern), as well as the medial region of the ilium. It is frequently associated with fractures of the supraacetabular region and the pubic symphysis. Computed tomography is the technique of choice for detecting the fracture line and/or sclerosis, although it is less sensitive than magnetic resonance (MR) imaging or scintigraphy during acute phases. MR of the above regions shows nonspecific edema, contrasting with hypointense signals indicating the general path of the fracture line in T2-weighted images. The use of gadolinium or fat suppression greatly increases the sensitivity. Bone scintigraphy is a highly sensitive diagnostic tool, although the H pattern occurs in less than 50% of cases.

Anesthesia management for patients with severe ankylosing spondylitis scheduled for total hip arthroplasty is challenging due to a potential difficult airway and difficult neuraxial block. We report 4 cases with ankylosing spondylitis successfully managed with a combination of lumbar plexus, sacral plexus and T12 paravertebral block. Four patients were scheduled for total hip arthroplasty. All of them were diagnosed as severe ankylosing spondylitis with rigidity and immobilization of cervical and lumbar spine and hip joints. A combination of T12 paravertebral block, lumbar plexus and sacral plexus block was successfully used for the surgery without any additional intravenous anesthetic or local anesthetics infiltration to the incision, and none of the patients complained of discomfort during the operations. The combination of T12 paravertebral block, lumbar plexus and sacral plexus block, which may block all nerves innervating the articular capsule, surrounding muscles and the skin involved in total hip arthroplasty, might be a promising alternative for total hip arthroplasty in ankylosing spondylitis.

Both interspecific and intraspecific variation in vertebral counts reflect the action of patterning control mechanisms such as Hox. The preserved A.L. 288-1 ("Lucy") sacrum contains five fused elements. However, the transverse processes of the most caudal element do not contact those of the segment immediately craniad to it, leaving incomplete sacral foramina on both sides. This conforms to the traditional definition of four-segmented sacra, which are very rare in humans and African apes. It was recently suggested that fossilization damage precludes interpretation of this specimen and that additional sacral-like features of its last segment (e.g., the extent of the sacral hiatus) suggest a general Australopithecus pattern of five sacral vertebrae. We provide updated descriptions of the original Lucy sacrum. We evaluate sacral/coccygeal variation in a large sample of extant hominoids and place it within the context of developmental variation in the mammalian vertebral column. We report that fossilization damage did not shorten the transverse processes of the fifth segment of Lucy's sacrum. In addition, we find that the extent of the sacral hiatus is too variable in apes and hominids to provide meaningful information on segment identity. Most importantly, a combination of sacral and coccygeal features is to be expected in vertebrae at regional boundaries. The sacral/caudal boundary appears to be displaced cranially in early hominids relative to extant African apes and humans, a condition consistent with the likely ancestral condition for Miocene hominoids. While not definitive in itself, a four-segmented sacrum accords well with the "long-back" model for the Pan/Homo last common ancestor.

The sacral foramina, particularly the first three, are not simple fenestrations. Each foramen is a Y-shaped complex of canals, all with indefinite margins. The complexes lie obliquely at approximately 45 0 to the coronal plane. An appreciation of these facts facilitates the recognition of the anatomy of plain films, tomographs, and computerized scans.

The median sacral artery (MSA) is a relatively small vessel that always arises from the posterior, terminal part of the infrarenal aorta. In most cases, the MSA runs behind the iliocaval junction. Here, we describe a very rare case of an MSA running in front of this junction. During a human cadaveric dissection of the retroperitoneal area, we unexpectedly observed that the MSA passed in front of the left common iliac vein. The anatomy of the MSA has been extensively described and variations are quite rare. On the basis of this specific case, knowledge of the anatomic interactions between the MSA and other lumbar retroperitoneal vessels may help to avoid potential complications during surgery.

PELVIS or SACRAL syndrome denotes the association of local haemangioma and malformation in the pelvic region. In this paper, we report a case noteworthy on account of the initially livedoid appearance of the haemangioma as well as associated amniotic banding of an upper limb. A newborn male infant underwent left colostomy on the day of birth due to anal imperforation and anomalies of the external genital organs with sexual ambiguity. Examination of the skin and appendages revealed poorly delineated hypopigmentation in the sacrolumbar region and a fibrous groove around the right arm characteristic of amniotic band syndrome. Sacrolumbar and pelvic MRI scans revealed deviation towards the left of the last three sacral vertebrae with no medullary anomalies. Retrograde cystography showed a recto-uretral fistula. Progression of the infant's condition was marked by the appearance during the first month of a flat, violaceous, angiomatous, livedoid lesion in the middle of the buttocks and the perineum and a linear lesion on the rear aspect of the right lower limb. The skin biopsy of this lesion revealed a single capillary lobule at the dermal-hypodermal junction of non-specific appearance but with marked Glut1 expression by endothelial cells highly evocative of infantile haemangioma. Segmented haemangiomas are commonly associated with extracutaneous abnormalities. By analogy with PHACE syndrome, defined as association of segmented facial haemangioma with cerebral, ocular and cardio-aortic abnormalities, PELVIS/SACRAL syndrome denotes the association of segmented haemangioma of the loins (sacrolumbar region, buttocks or perineum=napkin haemangioma) with spinal dysraphia affecting the sacrolumbar spine, the terminal medullary cone, the genitourinary organs and the anal region to different degrees. Diagnosis of haemangioma associated with PELVIS/SACRAL syndrome may be delayed or complicated due to the macular, telangiectasic or livedoid appearance commonly seen. To our

Placement of sacral fixation screws at surgery is performed blindly (ie, by palpation). The authors of this paper employed CT to localize the screw between the neutral foramina and anterior sacral cortex and to decrease the morbidity associated with general anesthesia and surgery. Six patients underwent CT-guided sacral fixation performed by means of the 7.0 mm A0 cannulated screw system. All patients had reducible vertical sacral fractures or sacroiliac joint disruptions. Following placement of an epidural catheter for anesthesia, patients were scanned in the prone or decubitus position. Measurements for placement of the guide pin were made from the preliminary scans. Following CT confirmation of satisfactory guide pin placement across the fracture, the screw track was drilled, the screw length was determined, and the fixation screw was placed in position. A CT scan was obtained to evaluate the final position of the screw

This exhibit demonstrates the utility of MR imaging in evaluating sacral and perisacral lesions. Thirty-two lesions were studied using a superconducting 1.0-T MR imager. Eleven primary and 13 metastatic tumors, four congenital lesions, and four arachnoid cysts were evaluated. MR did not usually enable a more specific histologic diagnosis than other imaging techniques. However, extraosseous and proximal spinal extent of tumors was well defined without use of oral or intravenous contrast material. MR imaging is an excellent noninvasive technique for evaluating most sacral and perisacral lesions and is particularly helpful when precise tumor extent must be determined for treatment planning

Neural tube defects in Waardenburg syndrome: A case report and review of the literature.

Hart, Joseph; Miriyala, Kalpana

Waardenburg syndrome type 1 (WS1) is an autosomal dominant genetic condition characterized by sensorineural deafness and pigment abnormalities, and is caused by variants in the PAX3 homeodomain. PAX3 variants have been associated with severe neural tube defects in mice and humans, but the frequency and clinical manifestations of this symptom remain largely unexplored in humans. Consequently, the role of PAX3 in human neural tube formation remains a study of interest, for clinical as well as research purposes. Though the association between spina bifida and WS1 is now well-documented, no study has attempted to characterize the range of spina bifida phenotypes seen in WS. Spina bifida encompasses several diagnoses with a wide scope of clinical severity, ranging from spina bifida occulta to myelomeningocele. We present a patient with Waardenburg syndrome type 1 caused by a novel missense variant in PAX3, presenting with myelomeningocele, Arnold-Chiari malformation, and hydrocephalus at birth. Additionally, we review 32 total cases of neural tube defects associated with WS. Including this report, there have been 15 published cases of myelomeningocele, 10 cases of unspecified spina bifida, 3 cases of sacral dimples, 0 cases of meningocele, and 4 cases of miscellaneous other neural tube defects. Though the true frequency of each phenotype cannot be determined from this collection of cases, these results demonstrate that Waardenburg syndrome type 1 carries a notable risk of severe neural tube defects, which has implications in prenatal and genetic counseling. © 2017 Wiley Periodicals, Inc.

Presacral abscess as a rare complication of sacral nerve stimulator implantation.

A 50-year-old man with intractable anal pain attributed to proctalgia fugax underwent insertion of a sacral nerve stimulator via the right S3 vertebral foramen for pain control with good symptomatic relief. Thirteen months later, he presented with signs of sepsis. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a large presacral abscess. MRI demonstrated increased enhancement along the pathway of the stimulator electrode, indicating that the abscess was caused by infection introduced at the time of sacral nerve stimulator placement. The patient was treated with broad spectrum antibiotics, and the sacral nerve stimulator and electrode were removed. Attempts were made to drain the abscess transrectally using minimally invasive techniques but these were unsuccessful and CT guided transperineal drainage was then performed. Despite this, the presacral abscess progressed, developing enlarging gas locules and extending to the pelvic brim to involve the aortic bifurcation, causing hydronephrosis and radiological signs of impending sacral osteomyelitis. MRI showed communication between the rectum and abscess resulting from transrectal drainage. In view of the progressive presacral sepsis, a laparotomy was performed with drainage of the abscess, closure of the upper rectum and formation of a defunctioning end sigmoid colostomy. Following this, the presacral infection resolved. Presacral abscess formation secondary to an infected sacral nerve stimulator electrode has not been reported previously. Our experience suggests that in a similar situation, the optimal management is to perform laparotomy with drainage of the presacral abscess together with simultaneous removal of the sacral nerve stimulator and electrode.

The purpose of our study was (1) to determine whether four-view radiography of the pelvis is as reliable and accurate as computed tomography (CT) in diagnosing sacral and pelvic fractures, in addition to coxofemoral and sacroiliac joint subluxation or luxation, and (2) to evaluate the effect of the amount of training in reading diagnostic imaging studies on the accuracy of diagnosing sacral and pelvic fractures in dogs. Sacral and pelvic fractures were created in 11 canine cadavers using a lateral impactor. In all cadavers, frog-legged ventro-dorsal, lateral, right and left ventro-45°-medial to dorsolateral oblique frog leg ("rollover 45-degree view") radiographs and a CT of the pelvis were obtained. Two radiologists, two surgeons and two veterinary students classified fractures using a confidence scale and noted the duration of evaluation for each imaging modality and case. The imaging results were compared to gross dissection. All evaluators required significantly more time to analyse CT images compared to radiographic images. Sacral and pelvic fractures, specifically those of the sacral body, ischiatic table, and the pubic bone, were more accurately diagnosed using CT compared to radiography. Fractures of the acetabulum and iliac body were diagnosed with similar accuracy (at least 86%) using either modality. Computed tomography is a better method for detecting canine sacral and some pelvic fractures compared to radiography. Computed tomography provided an accuracy of close to 100% in persons trained in evaluating CT images.

The cost of each intervention was based on the unit amount used in each type of dressing, and its purchase price (transparent film = R$15.80, hydrocolloid dressing = R$68.00). the mean cost/patient was R$23.17 for use of transparent film and R$190.40 for use of hydrocolloid dressing. The main reason for changing the dressing was detachment. the transparent film was the most economically advantageous alternative to prevent sacral pressure ulcers in critical care patients. However, additional studies should be carried out including assessment of the effectiveness of both dressings.

Lumbosacral transitional vertebrae (LSTV) are a relatively common variant and have been considered as one of the reasons for back pain. It is not unusual for clinicians to encounter patients with LSTV who require caudal epidural block (CEB) for pain management. We investigated the termination level of the dural sac (DS) and anatomical features of the lumbosacral region relevant to CEB in patients with LSTV and compared these findings between sacralization and lumbarization groups. A retrospective evaluation. A university hospital with inpatient and outpatient LSTV cases presenting low back pain. Four hundred ninety-four LSTV patients were included and categorized into sacralization (n = 201) or lumbarization groups (n = 293). Magnetic resonance imaging (MRI) of all of the LSTV patients were reviewed to determine the level of DS termination, the shortest distance between the apex of the sacral hiatus and DS, and the presence and the caudal level of sacral perineural cysts. Each lumbosacral vertebra column was divided into 3 equal portions (upper, middle, and lower thirds). The MRI findings in both of the groups were compared and analyzed. The distribution frequency of the levels of DS termination demonstrated a significant difference between the 2 groups. The mean caudal DS level in the lumbarization group was significantly lower than the sacralization group (lower third of the S2 [131 {44.7%} of 293 patients] vs. lower third of the S1 [78 {38.8%} of 201 patients]). The DS terminated at the S3 in more than 19% of the lumbarization group, whereas in only one case of the sacralization group. Although the incidence of perineural cysts was not significantly different between the 2 groups, the mean level of caudal margin of perineural cysts in the lumbarization group was significantly lower than the sacralization group (middle third of the S3 [10 {35.7%} of 28 cases] vs. middle third of the S2 [11 {44%} of 25 cases]). This study reveals several limitations including the

We developed a patient based educational video to address the information needs of women considering sacral nerve stimulation for overactive bladder. Five semistructured focus groups were used to identify patient knowledge gaps, information needs, patient acceptable terminology and video content preferences for a patient based sacral nerve stimulation educational video. Each session was transcribed, independently coded by 2 coders and examined using an iterative method. A 16-minute educational video was created to address previously identified knowledge gaps and information needs using patient footage, 3-dimensional animation and peer reviewed literature. We developed a questionnaire to evaluate participant sacral nerve stimulation knowledge and therapy attitudes. We then performed a randomized trial to assess the effect of the educational video vs the manufacturer video on patient knowledge and attitudes using our questionnaire. We identified 10 patient important domains, including 1) anatomy, 2) expectations, 3) sacral nerve stimulation device efficacy, 4) surgical procedure, 5) surgical/device complications, 6) post-procedure recovery, 7) sacral nerve stimulation side effects, 8) postoperative restrictions, 9) device maintenance and 10) general sacral nerve stimulation information. A total of 40 women with overactive bladder were randomized to watch the educational (20) or manufacturer (20) video. Knowledge scores improved in each group but the educational video group had a greater score improvement (76.6 vs 24.2 points, p <0.0001). Women who watched the educational video reported more favorable attitudes and expectations about sacral nerve stimulation therapy. Women with overactive bladder considering sacral nerve stimulation therapy have specific information needs. The video that we developed to address these needs was associated with improved short-term patient knowledge. Copyright © 2013 American Urological Association Education and Research, Inc

Transcutaneous sacral neurostimulation for irritative voiding dysfunction.

1999-01-01

Patients with irritative voiding dysfunction are often unresponsive to standard clinical treatment. We evaluated the response of such individuals to transcutaneous electrical stimulation of the third sacral nerve. 32 patients with refractory irritative voiding dysfunction (31 female and 1 male; mean age 47 years) were recruited to the study. Ambulatory transcutaneous electrical neurostimulation was applied bilaterally to the third sacral dermatomes for 1 week. Symptoms of frequency, nocturia, urgency, and bladder pain were scored by each patient throughout and up to 6 months following treatment. The mean daytime frequency was reduced from 11.3 to 7.96 (p = 0.01). Nocturia episodes were reduced from a mean of 2.6 to 1.8 (p = 0.01). Urgency and bladder pain mean symptom scores were reduced from 5.97 to 4.89 and from 1.48 to 0.64, respectively. After stopping therapy, symptoms returned to pretreatment levels within 2 weeks in 40% of the patients and within 6 months in 100%. Three patients who continued with neurostimulation remained satisfied with this treatment modality at 6 months. Transcutaneous third sacral nerve stimulation may be an effective and noninvasive ambulatory technique for the treatment of patients with refractory irritative voiding dysfunction. Following an initial response, patients may successfully apply this treatment themselves to ensure long-term relief.

Effectiveness and Value of Prophylactic 5-Layer Foam Sacral Dressings to Prevent Hospital-Acquired Pressure Injuries in Acute Care Hospitals: An Observational Cohort Study.

Padula, William V

The purpose of this study was to examine the effectiveness and value of prophylactic 5-layer foam sacral dressings to prevent hospital-acquired pressure injury rates in acute care settings. Retrospective observational cohort. We reviewed records of adult patients 18 years or older who were hospitalized at least 5 days across 38 acute care hospitals of the University Health System Consortium (UHC) and had a pressure injury as identified by Patient Safety Indicator #3 (PSI-03). All facilities are located in the United States. We collected longitudinal data pertaining to prophylactic 5-layer foam sacral dressings purchased by hospital-quarter for 38 academic medical centers between 2010 and 2015. Longitudinal data on acute care, hospital-level patient outcomes (eg, admissions and PSI-03 and pressure injury rate) were queried through the UHC clinical database/resource manager from the Johns Hopkins Medicine portal. Data on volumes of dressings purchased per UHC hospital were merged with UHC data. Mixed-effects negative binomial regression was used to test the longitudinal association of prophylactic foam sacral dressings on pressure injury rates, adjusted for hospital case-mix and Medicare payments rules. Significant pressure injury rate reductions in US acute care hospitals between 2010 and 2015 were associated with the adoption of prophylactic 5-layer foam sacral dressings within a prevention protocol (-1.0 cases/quarter; P = .002) and changes to Medicare payment rules in 2014 (-1.13 cases/quarter; P = .035). Prophylactic 5-layer foam sacral dressings are an effective component of a pressure injury prevention protocol. Hospitals adopting these technologies should expect good value for use of these products.

Sacral root neuromodulation in the treatment of various voiding and storage problems.

Shaker, H; Hassouna, M M

This paper reviews the use of sacral neuromodulation as a treatment modality for patients with bladder dysfunction. The dual functions of the urinary bladder are to act as a reservoir and to evacuate under voluntary control. Bladder dysfunction is a descriptive term describing the loss or the impairment of one or both of these functions. In the first part of the manuscript we describe the different components of sacral neuromodulation: the screening test known as percutaneous nerve evaluation (PNE), which involves screening patients who could potentially benefit from the therapy. Those who show a satisfactory response will have a permanent neuroprosthesis implanted. The technical aspects of both components of neuromodulation are described in detail, as well as the technical difficulties encountered. In the second part we present our long-term results in patients with sacral neuromodulation. Sacral neuromodulation is a safe and efficient therapeutic modality that helps patients with refractory voiding dysfunction restore their bladder function.

Neurolymphomatosis (NL) is a rare, unique subtype of lymphomatous infiltration of peripheral nerves. Clinical/radiologic diagnosis of NL is challenging. We report F-18 FDG PET/CT findings of a case of breast diffuse large B-cell lymphoma, in which NL developed regardless of regression of systemic lesions during induction chemotherapy. FDG PET/CT showed characteristic findings of well-demarcated, linear abnormal FDG uptake along a sacral vertebral foramen, leading to diagnosis of NL, with the finding of thickened nerve roots on magnetic resonance imaging. Altered chemotherapeutic regimen resulted in disappearance of these abnormal FDG uptake, with recovery of neurologic symptoms. Peripheral nerve NL may occur during chemotherapy, and FDG PET/CT can be a useful imaging modality in diagnosis and monitoring of therapeutic response of this disease.

MR myelography of sacral meningeal cysts

1999-01-01

Purpose: To describe the findings of sacral meningeal cysts (SMCs) on MR myelography and assess its value for the diagnosis of SMCs. Material and Methods: We evaluated the MR images and MR myelograms obtained from 10 patients with SMC. MR myelograms were obtained using a 2D or 3D single-shot fast spin-echo sequence. In 5 patients, X-ray myelograms and postmyelographic CT images were compared with the MR myelograms. Results: A total of 33 SMCs were diagnosed within the spinal canal and/or sacral foramen. MR myelograms clearly revealed each cyst as a well-defined mass showing hyperintensity (10 cysts) or isointensity (23 cysts) compared to cerebrospinal fluid. MR myelograms demonstrated SMCs better than X-ray myelograms and postmyelographic CT images in 3 of the 5 patients. Conclusion: MR myelography can be an adjunct to conventional imaging techniques when surgical treatment is indicated, because it can precisely delineate the extent of SMCs. (orig.)

Sacrality and worldmaking: new categorial perspectives

Directory of Open Access Journals (Sweden)

William E. Paden

1999-01-01

Full Text Available The category of the sacred in particular and the role of transcultural concept-formation in general have undergone an obvious crisis. For the most part, "the sacred," if not an empty label, has been linked with theologism, and transcultural concepts have been condemned for their general non-comparability and colonialist intent. The author approaches the matter of transcultural templates through an analysis of certain concepts of sacrality. With some exceptions, the discourse of sacrality has indeed been dominated by a single model, where "the sacred" became a reified noun—a substantive term for a supernatural reality, a label for the transcendent, or even an epithet for divinity, mystery, the wholly other. As such, the expression has functioned to bestow a sense of unity to the diversity of cultures, link that unity with a transcendent reality, and offer a simple way of making sense of otherwise foreign beliefs and practices by giving them a familiar, generic referent.

Sacral nerve root neuromodulation: an effective treatment for refractory urge incontinence.

Shaker, H S; Hassouna, M

1998-05-01

Sacral foramina implants have been recognized recently as a method for treatment of refractory urinary urge incontinence. We study the outcome of the procedure with in-depth analysis of the results of 18 implanted cases. Patients with urinary urge incontinence were subjected to percutaneous nerve evaluation of the S3 roots as a temporary screening test to determine response to neuromodulation. Satisfactory responders were implanted with permanent sacral root neuroprosthesis. The study design included comprehensive voiding diaries for 4 consecutive days twice as a baseline, 1 with percutaneous nerve evaluation screening, 1 after the percutaneous nerve evaluation, 1 at the 1, 3 and 6 post-implantation visits, and every 6 months thereafter. Uroflowmetry and quality of life questionnaires were performed at the same intervals. Urodynamic study was done as a baseline and 6 months after implantation of the neuroprosthesis. All 18 patients (16 women and 2 men) with refractory urge incontinence received a sacral foramina neuroprosthesis after demonstrating a good response to the percutaneous nerve evaluation. Average patient age at presentation was 42.3+/-3.3 years (range 22 to 67) and duration of urinary symptoms was 6.6+/-1.3 years (range 1.2 to 18.8). Average followup was 18.8 months (range 3 to 83). Neuromodulation in these patients showed a marked reduction in leakage episodes from 6.49 to 1.98 times per 24 hours and in the leakage severity score. Eight patients became completely dry and 4 had average leakage episodes of 1 or less daily. Patients showed as well a decrease in urinary frequency with an increase in functional bladder capacity. Associated pelvic pain improved substantially. Cystometrograms demonstrated increased volume at first sensation by 50% and increased cystometric capacity by 15% with the disappearance of uninhibited contractions in 1 of the 4 patients who presented with it preoperatively. There was also noticeable improvement in the quality of life

Sacral root neuromodulation is becoming a superior alternative to the standard treatment of idiopathic nonobstructive urinary retention. We report results in 20 successive patients who underwent sacral foramen implantation to restore bladder function. After an initial, thorough baseline assessment 20 patients 19.43 to 55.66 years old with idiopathic nonobstructive urinary retention underwent percutaneous nerve evaluation. Response was assessed by a detailed voiding diary. Responders underwent implantation with an S3 foramen implant, and were followed 1, 3 and 6 months postoperatively, and every 6 months thereafter. Sacral root neuromodulation restored voiding capability in these patients. Bladders were emptied with minimal post-void residual urine, which decreased from 78.3 to 5.5 to 10.2% of the total voided volume from baseline to postoperative followup. These results were reflected in uroflowmetry and pressure-flow studies, which were almost normal after implantation. Furthermore, the urinary tract infection rate decreased significantly and associated pelvic pain improved substantially. The Beck depression inventory and SF-36 quality of life questionnaire indicated some improvement but reached significance in only 1 item. In addition, cystometrography showed no significant difference after 6 months of implantation compared with baseline values. Complications were minimal and within expectations. Sacral root neuromodulation is an appealing, successful modality for nonobstructive urinary retention. Only patients who have a good response to percutaneous nerve evaluation are candidates for implantation. The high efficacy in patients who undergo implantation, relative simplicity of the procedure and low complication rate make this a treatment breakthrough in this difficult group.

The sacral region is one of the most vulnerable sites for the development of pressure sores. Even when surgical reconstruction is performed, there is a high chance of recurrence. Therefore, the concept of dual-dermal-barrier fashion flaps for sacral pressure sore reconstruction was proposed. From September 2007 to June 2010, nine patients with grade IV sacral pressures were enrolled. Four patients received bilateral myocutaneous V-Y flaps, four patients received bilateral fasciocutaneous V-Y flaps, and one patient received bilateral rotation-advanced flaps for sacral pressure reconstruction. The flaps were designed based on the perforators of the superior gluteal artery in one patient's reconstructive procedure. All flaps' designs were based on dual-dermal-barrier fashion. The mean follow-up time was 16 months (range = 12-25). No recurrence was noted. Only one patient had a complication of mild dehiscence at the middle suture line, occurring 2 weeks after the reconstructive surgery. The dual-dermal fashion flaps are easily duplicated and versatile. The study has shown minimal morbidity and a reasonable outcome.

Bosch, J L

1998-07-01

Sacral neuromodulation as a treatment for urge incontinence in patients with an unstable bladder is the subject of ongoing clinical studies. Although approximately 75% of the patients treated with a permanent sacral foramen electrode implant have experienced significant improvements, it is now also clear that there is an initial failure rate of about 25%. Recent studies have pointed out the importance of improved patient selection on the basis of sex differences, urodynamic parameters and psychological factors. Also, newer forms of test stimulation and permanent electrode implantation are being explored in an effort to improve on the present results.

Abstract Objective This study aimed to evaluate the validity of the sacral base pressure test in diagnosing sacroiliac joint dysfunction. It also determined the predictive powers of the test in determining which type of sacroiliac joint dysfunction was present. Methods This was a double-blind experimental study with 62 participants. The results from the sacral base pressure test were compared against a cluster of previously validated tests of sacroiliac joint dysfunction to determine its validity and predictive powers. The external rotation of the feet, occurring during the sacral base pressure test, was measured using a digital inclinometer. Results There was no statistically significant difference in the results of the sacral base pressure test between the types of sacroiliac joint dysfunction. In terms of the results of validity, the sacral base pressure test was useful in identifying positive values of sacroiliac joint dysfunction. It was fairly helpful in correctly diagnosing patients with negative test results; however, it had only a “slight” agreement with the diagnosis for κ interpretation. Conclusions In this study, the sacral base pressure test was not a valid test for determining the presence of sacroiliac joint dysfunction or the type of dysfunction present. Further research comparing the agreement of the sacral base pressure test or other sacroiliac joint dysfunction tests with a criterion standard of diagnosis is necessary. PMID:19674694

1988-01-01

One hundred fifty children with congenital malformations of the spine were studied with MR imaging, US, and water-soluble myelography with CT. The malformations encountered included myelomeningoceles and Chiari II malformations, diastematomyelia, hydromyelia, arachnoid cyst, dermal sinus and dermoid, spinal lipomas and teratomas, tight filum terminale, anterior sacral meningoceles, lipomyelomeningoceles, myelocystocele, and severe scoliosis. MR imaging was the most effective modality in delineating these abnormalities. At times, real-time US and water-soluble CT myelography were required as adjuncts to MR imaging in delineating subtle spinal cord tethering, arachnoid cyst, diastematomyelia, and severe scoliosis

Conventional sacral anterior root stimulation (SARS) results in simultaneous activation of both the detrusor muscle and the external urethral sphincter. We evaluated the possibilities of different neurostimulation techniques to overcome stimulation induced detrusor-sphincter-dyssynergia and to achieve a physiological voiding. The literature was reviewed on different techniques of sacral anterior root stimulation of the bladder and the significance of posterior rhizotomy in patients with supraconal spinal cord injury suffering from the loss of voluntary bladder control, detrusor hyperreflexia and sphincter spasm. The achievement of selective detrusor activation would improve current sacral neurostimulation of the bladder, including the principle of "poststimulus voiding". This is possible with the application of selective neurostimulation in techniques of anodal block, high frequency block, depolarizing prepulses and cold block. Nowadays, sacral deafferentation is a standard therapy in combination with neurostimulation of the bladder because in conclusion advantages of complete rhizotomy predominate. The combination of sacral anterior root stimulation and sacral deafferentation is a successful procedure for restoration of bladder function in patients with supraconal spinal cord injury. Anodal block technique and cryotechnique are excellent methods for selective bladder activation to avoid detrusor-sphincter-dyssynergia and thus improve stimulation induced voiding.

Full Text Available IntroductionSacral chordomas represent one half of all chordomas, a rare neoplasm of notochordal remnants. Current NCCN guidelines recommend surgical resection with or without adjuvant radiotherapy, or definitive radiation for unresectable cases. Recent advances in radiation for chordomas include conformal photon and proton beam radiation. We investigated incidence, treatment, and survival outcomes to observe any trends in response to improvements in surgical and radiation techniques over a near 40 year time period.Materials and Methods345 microscopically confirmed cases of sacral chordoma were identified between 1974 and 2011 from the Surveillance, Epidemiology, and End Results (SEER program of the National Cancer Institute. Cases were divided into three cohorts by calendar year, 1974-1989, 1990-1999, and 2000-2011, as well as into two groups by age less than or equal to 65 versus greater than 65 to investigate trends over time and age via Chi-square analysis. Kaplan-Meier analyses were performed to determine effects of treatment on survival. Multivariate Cox regression analysis was performed to determine predictors of overall survival.Results5-year overall survival for the entire cohort was 60.0%. Overall survival correlated significantly with treatment modality, with 44% surviving at 5 years with no treatment, 52% with radiation alone, 82% surgery alone, and 78% surgery and radiation (p<.001. Age greater than 65 was significantly associated with non-surgical management with radiation alone or no treatment (p<.001. Relatively fewer patients received radiation between 2000 and 2011 compared to prior time periods (p=.03 versus surgery, for which rates which did not vary significantly over time (p=.55. However, 5-year overall survival was not significantly different by time period. Age group and treatment modality were predictive for overall survival on multivariate analysis (p<.001.

Sacral nerve stimulation has become a preferred method for the treatment of faecal incontinence in patients who fail conservative (non-operative) therapy. In previous small studies, sacral nerve stimulation has demonstrated improvement of faecal incontinence and quality of life in a majority of patients with low anterior resection syndrome. We evaluated the efficacy of sacral nerve stimulation in the treatment of low anterior resection syndrome using a recently developed and validated low anterior resection syndrome instrument to quantify symptoms. A retrospective review of consecutive patients undergoing sacral nerve stimulation for the treatment of low anterior resection syndrome was performed. Procedures took place in the Division of Colon and Rectal Surgery at two academic tertiary medical centres. Pre- and post-treatment Cleveland Clinic Incontinence Scores and Low Anterior Resection Syndrome scores were assessed. Twelve patients (50% men) suffering from low anterior resection syndrome with a mean age of 67.8 (±10.8) years underwent sacral nerve test stimulation. Ten patients (83%) proceeded to permanent implantation. Median time from anterior resection to stimulator implant was 16 (range 5-108) months. At a median follow-up of 19.5 (range 4-42) months, there were significant improvements in Cleveland Clinic Incontinence Scores and Low Anterior Resection Syndrome scores (P syndrome and may therefore be a viable treatment option.

To quantify the osseous anatomy of the dysmorphic third sacral segment and assess its ability to accommodate internal fixation. Retrospective chart review of a trauma database. University Level 1 Trauma Center. Fifty-nine patients over the age of 18 with computed tomography scans of the pelvis separated into 2 groups: a group with normal pelvic anatomy and a group with sacral dysmorphism. The sacral osseous area was measured on computed tomography scans in the axial, coronal, and sagittal planes in normal and dysmorphic pelves. These measurements were used to determine the possibility of accommodating a transiliac transsacral screw in the third sacral segment. In the normal group, the S3 coronal transverse width averaged 7.71 mm and the S3 axial transverse width averaged 7.12 mm. The mean S3 cross-sectional area of the normal group was 55.8 mm. The dysmorphic group was found to have a mean S3 coronal transverse width of 9.49 mm, an average S3 axial transverse width of 9.14 mm, and an S3 cross-sectional area of 77.9 mm. The third sacral segment of dysmorphic sacra has a larger osseous pathway available to safely accommodate a transiliac transsacral screw when compared with normal sacra. The S3 segment of dysmorphic sacra can serve as an additional site for screw placement when treating unstable posterior pelvic ring fractures.

The Effect of Early Complications on Flap Selection on Sacral Pressure Sores

Directory of Open Access Journals (Sweden)

Musa Kemal Keleş

2017-06-01

Full Text Available Objective: Pressure sores occur in bedridden patients in intensive care units, clinics, and even at their own places. Care for sick relatives and working with doctors to address treatment options and ensure proper follow-up are some of the problems associated with these types of wounds. Surgical therapy in the treatment of pressure ulcers is associated with significant complications. In comparison to non-surgical treatment, surgical treatment has a low complication rate and is more cost-effective. The surgical treatment enables the patients to return to their social life sooner than non-surgical treatment. Patient's ability to early return to their social life is advantageous in terms of reducing morbidity and the need for additional operations. This study is aimed to review the flap choices used to treat sacral pressure sores and the resulting acute complications rates retrospectively. Material and Methods: Patients treated for stage 3 and stage 4 sacral pressure sores in our clinic in the past 5 years were included in the study. Patient records were analyzed retrospectively. Patients' demographic data and surgical treatment they received were documented. Surgical method and surgical outcomes were evaluated and early complication rates were determined. Result: Fifty patients were included in the study; 10 of them were female, 40 of were male cases. The most common causative agent was paraplegia after traffic accident. Conclusion: A significant difference was not observed between the type of flap used in the surgical treatment and the rate of complications. Consequently, the surgical treatment of pressure ulcers in the sacral region depends on the patient's individual situation, the cooperation of the family, and previously applied treatments

Identifying relationships among anatomical structures is key in diagnosing somatic dysfunction. Ultrasonography can be used to visualize anatomical structures, identify sacroiliac landmarks, and validate anatomical findings and measurements in relation to somatic dysfunction. As part of the osteopathic manipulative medicine course at A.T. Still University-Kirksville College of Osteopathic Medicine, first-year students are trained to use ultrasonography to establish relationships among musculoskeletal structures. To determine the ability of first-year osteopathic medical students to establish sacral base position (SBP) and sacral sulcus depth (SSD) using ultrasonography and to identify the relationship of SBP and SSD to body mass index (BMI) and sex. Students used ultrasonography to obtain the distance between the skin and the sacral base (the SBP) and the distance between the skin and the tip of the posterior superior iliac spine bilaterally. Next, students calculated the SSD (the distance between the tip of the posterior superior iliac spine and the SBP). Data were analyzed with respect to side of the body, BMI, sex, and age. The BMI data were subdivided into normal (18-25 mg/kg) and overweight (25-30 mg/kg) groups. Ultrasound images of 211 students were included in the study. The SBP was not significantly different between the left and right sides (36.5 mm vs 36.5 mm; P=.95) but was significantly different between normal and overweight BMI categories (33.0 mm vs 40.0 mm; Psex may point to more soft tissue overlaying the sacrum in these groups. Further research is needed on the use of ultrasonography to establish criteria for somatic dysfunction.

Spinal CT scan, 2. Lumbar and sacral spines

Plain CT described fairly accurately the anatomy and lesions of the lumbar and sacral spines on their transverse sections. Since hernia of the intervertebral disc could be directly diagnosed by CT, indications of myelography could be restricted. Spinal-canal stenosis of the lumbar spine occurs because of various factors, and CT not only demonstrated the accurate size and morphology of bony canals, but also elucidated thickening of the joints and yellow ligament. CT was also useful for the diagnosis of tumors in the lumbar and sacral spines, visualizing the images of bone changes and soft tissues on the trasverse sections. But the diagnosis of intradural tumors required myelography and metrizamide CT. CT has become important for the diagnosis of spinal and spinal-cord diseases and for selection of the route of surgical arrival.

The existing literature on preoperative spine tumor embolization is limited in size of patient cohorts and diversity of tumor histologies. This report presents our experience with preoperative embolization of hypervascular thoracic, lumbar, and sacral spinal column tumors in the largest series to date. We conducted a retrospective review of 228 angiograms and 188 pre-operative embolizations for tumors involving thoracic, lumbar and sacral spinal column. Tumor vascularity was evaluated with conventional spinal angiography and was graded from 0 (same as normal adjacent vertebral body) to 3 (severe tumor blush with arteriovenous shunting). Embolic materials included poly vinyl alcohol (PVA) particles and detachable platinum coils and rarely, liquid embolics. The degree of embolization was graded as complete, near-complete, or partial. Anesthesia records were reviewed to document blood loss during surgery. Renal cell carcinoma (44.2%), thyroid carcinoma (9.2%), and leiomyosarcoma (6.6%) were the most common tumors out of a total of 40 tumor histologies. Hemangiopericytoma had the highest mean vascularity (2.6) of all tumor types with at least five representative cases followed by renal cell carcinoma (2.0) and thyroid carcinoma (2.0). PVA particles were used in 100% of cases. Detachable platinum coils were used in 51.6% of cases. Complete, near-complete, and partial embolizations were achieved in 86.1%, 12.7%, and 1.2% of all cases, respectively. There were no new post-procedure neurologic deficits or other complications with long-term morbidity. The mean intra-operative blood loss for the hypervascular tumors treated with pre-operative embolization was 1745 cc. Preoperative embolization of hypervascular thoracic, lumbar, and sacral spine tumors can be performed with high success rates and a high degree of safety at high volume centers.

A case of von Willebrand disease discovered during treatment of a sacral pressure ulcer.

Science.gov (United States)

2010-12-01

A sacral pressure ulcer developed in a patient hospitalized for cerebral infarction. Each time necrotic tissue was debrided from the ulcer, pressure hemostasis was necessary to stop the bleeding. As treatment continued, the pressure required to stop the bleeding caused the ulcer to worsen, leading to a downward spiral in the patient's condition. While trying to determine the cause of this problem, we discovered that the patient had von Willebrand disease. Medication controlled the bleeding, and the pressure ulcer began to heal at the same time. It was clear to us that conservative treatment would lead to a complete cure but that the healing process would take a long time and require continued administration of an expensive drug. We decided, therefore, to close the wound with a fasciocutaneous flap so that the patient could be quickly transferred to a rehabilitation hospital. About 1 month after surgery, epithelialization was complete, we were able to discontinue medication, and the patient was discharged. This experience demonstrates the importance of determining the cause of any deviation from the normal course of healing in pressure ulcers. It also indicates that the use of fasciocutaneous flaps, which involve little intraoperative bleeding in short surgeries, is appropriate in cases like this one.

Pressure sore rates remain high in both nursing homes as well as in hospitals. Numerous surgical options are available for defect coverage in the sacral region. However, objective data is scarce as to whether a specific flap design is superior to another. Here, we aim to compare two fasciocutaneous flap designs for sacral defect coverage: the gluteal rotation flap and the gluteal V-Y flap. All primary sacral pressure sores of grades III-IV that were being covered with gluteal fasciocutaneous rotational or V-Y flaps between January 2008 and December 2014 at our institution were analysed. A total of 41 patients received a total of 52 flaps. Of these, 18 patients received 20 gluteal rotational flaps, and 23 patients received 32 V-Y flaps. Both groups were comparable with regards to demographics, comorbidities and complications. Significantly more V-Y flaps were needed to cover smaller defects. Mean length of hospital stay was significantly prolonged when surgical revision had to be carried out. Both flap designs have proven safe and reliable for defect coverage after sacral pressure sores. Gluteal rotational flaps appear to be more useful for larger defects. Both flap designs facilitate their reuse in case of pressure sore recurrence. Complication rates appear to be comparable in both designs and to the current literature. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Full Text Available A 15-yr old boy presented with low backache for 4 months associated with weakness of left lower limb. MRI of lumbosacral spine showed a sacral lesion with intraspinal and presacral soft tissue extension with neural compression. A diagnosis of tuberculosis was considered in the view of high prevalence in this part of the world, however biopsy revealed Ewing's sarcoma. Ewing's tumor of sacrum is rare, but should be suspected in low backache in children. Differential diagnosis for a sacral lesion includes tuberculosis, pyogenic osteomyelitis, lymphoma, chordoma, osteosarcoma and Ewing's sarcoma. MRI is sensitive in detecting these lesions but is nonspecific requiring histopathological examination for confirmation.

Objective: To analyze the efficacy and safety of CT-guided percutaneous injection of the fibrin glue by 'double needle' technique to treat sacral cyst. Methods: Clinical data of 20 cases with 'double-needle' injection of fibrin glue technology to treat sacral cyst were retrospectively analyzed. All patients had varying degrees of sacral nerve root compression symptoms. The treatment for sacral cyst was carried out after clear diagnosis was made. On the basis of CT-guided percutaneous injection of fibrin glue, the improved CT-guided percutaneous injection of fibrin glue by 'double-needle' technique was used to treat these patients. The average dose of fibrin glue was (5.9 ± 2.4) ml. The clinical results of improvement as to pain and neurological function were evaluated after follow-up of an average of 17 months. The assessment criteria were as follows: excellent, complete resolution of signs and symptoms, with the patient returning to his or her regular employment and no recurrence of cysts during 1 year of follow-up, good, symptoms and signs in the legs and perineal region resolved but with persistent pain in the lumbosacral region, which did not interfere with the patient's regular work (the cysts did not recur for 6 months during follow-up), fair, no improvement in clinical symptoms, but a decrease in cyst size on the imaging study, poor, no improvement in clinical symptoms and no observed changes in cyst size in imaging studies or recurrence. Results: Most patients experienced some degree of pain relief and functional improvement after fibrin glue therapy, with most experiencing complete or marked resolution of clinical symptoms. Nine patients reported excellent recovery, 8 reported good recovery, 2 reported fair recovery, and 1 reported poor recovery. The overall percentage of positive outcomes (excellent and good recovery) was 85%. No serious postoperative complications were discovered. Conclusions: CT guided percutaneous injection of the fibrin glue by

Myelography and CT myelography (CMT) were reviewed in 18 cases of birth palsy with clinically suspected avulsion injury. Root-somatosensory evoked potential (root-SEP) was also reviewed for myelographic evaluation of the nerve root avolusion in birth palsy. Root-SEP is not induced in case of avulsed nerve roots, but is induced in case of both normal and incompletely avulsed roots. Myelography demonstrated 58 abnormal nerve roots in 18 cases (19 limbs); 45 (78%) complete and 13 (22%) incomplete nerve root avulsions. Each of complete and incomplete avulsions was defined as total absence and partial presence of rootlets on myelography, respectively. Traumatic meningoceles were detected at 46 roots (79%) on myelography and/or CTM; 35 roots on myelography and 45 roots on CTM. CTM could not detect only a very small meningocele at one root. At 11 roots CTM was superior to myelography in delineating a meningocele because CTM is sensitive to a poorly enhanced meningocele. CTM, however, could not diagnose nerve root avulsions so accurately as myelography, since myelography detected 12 (7 completely and 5 incompletely) avulsed roots without meningocele, whereas CTM could not delineate the nerve roots clearly. Thus, myelography is indispensable to evaluate nerve root avulsions without meningocele. Root-SEP was examined in 9 patients who underwent branchial plexus exploration. SEP was negative at 22/25 roots with complete avulsion and was positive at 7/7 roots with myelographically incomplete avulsion, regardless of presence or absence of any traumatic meningocele. Myelography and root-SEP correlated well at 29 (92%) out of 32 roots in evaluating complete and incomplete avulsion injuries. Myelography and root-SEP were not considered in 3 roots. Though myelography demonstrated complete avulsions with traumatic meningocele, SEP was positive in these three roots, which were interpreted as partially avulsed roots. (J.P.N.).

Pelvic ring stability is maintained passively by both the osseous and the ligamentous apparatus. Therapeutic approaches focus mainly on fracture patterns, so ligaments are often neglected. When they rupture along with the bone after pelvic ring fractures, disrupting stability, ligaments need to be considered during reconstruction and rehabilitation. Our aim was to determine the influence of ligaments on open-book injury using two experimental models with body donors. Mechanisms of bone avulsion related to open-book injury were investigated. Open-book injuries were induced in human pelves and subsequently investigated by anatomical dissection and endoscopy. The findings were compared to CT and MRI scans of open-book injuries. Relevant structures were further analyzed using plastinated cross-sections of the posterior pelvic ring. A fragment of the distal sacrum was observed, related to open-book injury. Two ligaments were found to be responsible for this avulsion phenomenon: the caudal portion of the anterior sacroiliac ligament and another ligament running along the ventral surface of the third sacral vertebra. The sacral fragment remained attached to the coxal bone by this second ligament after open-book injury. These results were validated using plastination and the structures were identified. Pelvic ligaments are probably involved in sacral avulsion caused by lateral traction. Therefore, ligaments should to be taken into account in diagnosis of open-book injury and subsequent therapy.

The mechanism of sacral neuromodulation is poorly understood. We compared brain activity during urgency before and after sacral neuromodulation in women with overactive bladder and according to response to treatment. Women with refractory overactive bladder who elected for sacral neuromodulation were invited to undergo a functional magnetic resonance imaging exam before and after treatment. During the imaging exams, the bladder was filled until urgency was experienced. Regions of interest were identified a priori, and brain activity in these regions of interest was compared before and after treatment as well as according to treatment response. A whole brain exploratory analysis with an uncorrected voxel level threshold of pbrain regions that changed after sacral neuromodulation. Among 12 women who underwent a pretreatment functional magnetic resonance imaging exam, seven were successfully treated with sacral neuromodulation and underwent a posttreatment exam. After sacral neuromodulation, brain activity decreased in the left anterior cingulate cortex, bilateral insula, left dorsolateral prefrontal cortex and bilateral orbitofrontal cortex (all pbrain regions with increased activity after sacral neuromodulation. Pretreatment brain activity levels in the bilateral anterior cingulate cortex, right insula, bilateral dorsolateral prefrontal cortex, right orbitofrontal cortex, right supplementary motor area, and right sensorimotor cortex were higher in women who underwent successful treatment (all pBrain activity during urgency changes after successful sacral neuromodulation. Sacral neuromodulation may be more effective in women with higher levels of pretreatment brain activity during urgency. Copyright © 2018 American Urological Association Education and Research, Inc.

A method is described for percutaneous localization of the sacral foramina, for neuromodulation of bladder function. We carried out an anatomical study of 5 male and 5 female human cadaver pelves. Using the described surface markings, needles were placed percutaneously into all sacral foramina from nine different angles. Paths of needle entry were studied by subsequent dissection. We observed that although it was possible to enter any sacral foramen at a wide range of insertion angles, the incidence of nerve root/vascular penetration increased with increasing angle of needle entry. Also, the incidence of nerve root penetration was higher with the medial approach compared with lateral entry. The insertion of a needle into the S1 foramen was associated with a higher incidence of nerve root penetration and presents a potential for arterial haemorrhage. On the other hand the smaller S3 and S4 nerve roots were surrounded by venous plexuses, presenting a potential source of venous haemorrhage during procedures. Our study suggests a new method for identifying the surface markings of sacral foramina and it describes the paths of inserted needles into the respective foramina. In addition, it has highlighted some potential risk factors secondary to needle insertion.

Temporary electrical stimulation using anal or vaginal electrodes and an external pulse generator has been a treatment modality for urinary urge incontinence for nearly three decades. In 1981 Tanagho and Schmidt introduced chronic electrical stimulation of the sacral spinal nerves using a permanently implanted sacral foramen electrode and a battery powered pulse generator for treatment of different kinds of lower urinary tract dysfunction, refractory to conservative treatment. At our department chronic unilateral electrical stimulation of the S3 sacral spinal nerve has been used for treatment of vesi-courethral dysfunction in 43 patients with a mean postoperative follow up of 43,6 months. Lasting symptomatic improvement by more than 50 % could be achieved in 13 of 18 patients with motor urge incontinence (72,2 %) and in 18 of the 21 patients with urinary retention (85,7 %). Implants offer a sustained therapeutic effect to treatment responders, which is not achieved by temporary neuromodulation. Chronic neuromodulation should be predominantly considered in patients with urinary retention. Furthermore in patients with motor urge incontinence, refusing temporary techniques or in those requiring too much effort to achieve a sustained clinical effect. Despite high initial costs chronic sacral neuromodulation is an economically reasonable treatment option in the long run, when comparing it to the more invasive remaining therapeutic alternatives.

Urinary retention and micturition disorders after overdistension are clinically well-known complications of subvesical obstruction. We attempted to evaluate whether bladder overdistension influences bladder response and whether overdistension supports detrusor decompensation. Following lumbal laminectomy in 9 male foxhounds, the sacral anterior roots S2 and S3 were placed into a modified Brindley electrode for reproducible and controlled detrusor activation. The bladder was filled in stages of 50 ml from 0 to 700 ml, corresponding to an overdistension. At each volume, the bladder response during sacral anterior root stimulation was registered. After overdistension, the bladder was refilled stepwise from 0 to 300 ml and stimulated. In all dogs, the bladder response was influenced by the intravesical volume. The maximum pressure (mean 69.1 cm H(2)O) was observed at mean volume of 100 ml. During overdistension, a significant reduction in bladder response of more than 80% was seen. After overdistension, a significant reduction in intravesical pressure of 19.0% was observed. In 2 cases, reduction in bladder response was more than 50% after a single overdistension. We conclude that motoric bladder function is influenced during and after overdistension. A single bladder overdistension can support acute and long-lasting detrusor decompensation. In order to protect motoric bladder function, bladder overdistension must be prevented.

This study aimed to characterize pertinent anatomy relative to the sacral suture placed at time of robotic sacrocolpopexy using postoperative computed tomography and magnetic resonance imaging. A vascular clip was placed at the base of the sacral suture at the time of robotic sacrocolpopexy. Six weeks postoperatively, subjects returned for a computed tomography scan and magnetic resonance imaging. Ten subjects completed the study. The middle sacral artery and vein coursed midline or to the left of midline in all the subjects. The left common iliac vein was an average of 26 mm from the sacral suture. To the right of the suture, the right common iliac artery was 18 mm away. Following the right common iliac artery to its bifurcation, the right internal iliac was on average 10 mm from the suture. The bifurcations of the inferior vena cava and the aorta were 33 mm and 54 mm further cephalad, respectively.The right ureter, on average, was 18 mm from the suture. The thickness of the anterior longitudinal ligament was 2 mm.The mean angle of descent of the sacrum was 70 degrees. Lastly, we found that 70% of the time, a vertebral body was directly below the suture; the disc was noted in 30%. We describe critical anatomy surrounding the sacral suture placed during robotic sacrocolpopexy. Proximity of both vascular and urologic structures within 10 to 18 mm, as well as anterior ligament thickness of only 2 mm highlights the importance of adequate exposure, careful dissection, and surgeon expertise.

The posterior rings of the lower lumbo-sacral vertebrae are subject to stress fractures at any part - pedicle, pars, or lamina. The site of fracture is apparently determined by the axis of weight bearing. The three illustrative clinical examples cited include a jogger with a laminar fracture, a ballet dancer with pedicle fractures, and a nine-year-old boy with fractures of pars and lamina. Chronic low back pain is the typical complaint with stress fractures of the lower lumbo-sacral spine. Special imaging techniques are usually needed to demonstrate these lesions, including vertebral arch views, multi-directional tomography, and computed tomography (CT). (orig.)

A descriptive study (based on skeletal material) was designed to measure sacral anatomic orientation (SAO) in individuals with and without spondylolysis. To test whether a relationship between SAO and spondylolysis exists. Spondylolysis is a stress fracture in the pars interarticularis (mainly of L5). The natural history of the phenomenon has been debated for years with opinions divided, i.e., is it a developmental condition or a stress fracture phenomenon. There is some evidence to suggest that sacral orientation can be a "key player" in revealing the etiology of spondylolysis. The pelvis was anatomically reconstructed and SAO was measured as the angle created between the intersection of a line running parallel to the superior surface of the sacrum and a line running between the anterior superior iliac spine (ASIS) and the anterior-superior edge of the symphysis pubis (PUBIS).SAO was measured in 99 adult males with spondylolysis and 125 adult males without spondylolysis. The difference between the groups was tested using an unpaired t test. Spondylolysis prevalence is significantly higher in African-Americans compared to European-Americans: 5.4% versus 2.04% in males (P < 0.001) and 2.31% versus 0.4%, P < 0.001 in females. SAO was significantly lower in the spondylolytic group (44.07 degrees +/- 11.46 degrees) compared to the control group (51.07 degrees +/- 8.46 degrees, P < 0.001). A more horizontally oriented sacrum leads to direct impingement on L5 pars interarticularis by both L4 inferior articular facet superiorly and S1 superior articular facet inferiorly. Repetitive stress due to standing (daily activities) or sitting increases the "pincer effect" on this area, and eventually may lead to incomplete synostosis of the neural arch.

Full Text Available Introduction: Decubitus ulcers of the sacral region are common conditions in bedridden patients. Deep lesions (Stages III and IV often require surgical treatment for closure. Flaps of the region are the first choice for treatment. We present our experience in the treatment of these lesions and compare two different approaches: local fasciocutaneous flap and gluteus maximus myocutaneous flap with V-Y advancement. Method: From March 2009 to May 2014, 32 patients underwent closure of sacral pressure ulcers by flaps, 17 of them with rotational local fasciocutaneous flaps and 15 with myocutaneous flaps of the gluteus maximus muscle with V-Y advancement. Evolution regarding complications and rate of success after two months was compared between the groups. Results: Out of the 32 operated patients we obtained resolution of lesions after two months in 23 (71.8%, 10 patients in the fasciocutaneous flap group (58.8% and 13 cases in the myocutaneous flap group (86.6%. The most common complication was partial dehiscence of sutures in 12 patients (37.5%, 8 patients in the fasciocutaneous flap group (47% and 4 patients in the myocutaneous flap group (26.6%. The group of patients reconstructed with local fasciocutaneous flaps presented 3 cases with seroma, one with hematoma and 6 with partial cutaneous necrosis; these patients also required more drainage time. Conclusions: Both the local rotational fasciocutaneous flap and the myocutaneous flap of the gluteus maximus muscle in V-Y flap can be used in the surgical treatment of sacral ulcers. In our experience, a reduced success rate and more complications were found in the local fasciocutaneous reconstructive method.

Purpose A sacral chordoma is a rare, slow-growing, primary bone tumor, arising from embryonic notochordal remnants. Radical surgery is the only hope for cure. The aim of our present study is to analyse our experience with the challenging treatment of this rare tumor, to review current treatment modalities and to assess the outcome based on R status. Methods Eight patients were treated in our institution between 2001 and 2011. All patients were discussed by a multidisciplinary tumor board, and an en bloc surgical resection by posterior perineal access only or by combined anterior/posterior accesses was planned based on tumor extension. Results Seven patients underwent radical surgery, and one was treated by using local cryotherapy alone due to low performance status. Three misdiagnosed patients had primary surgery at another hospital with R1 margins. Reresection margins in our institution were R1 in two and R0 in one, and all three recurred. Four patients were primarily operated on at our institution and had en bloc surgery with R0 resection margins. One had local recurrence after 18 months. The overall morbidity rate was 86% (6/7 patients) and was mostly related to the perineal wound. Overall, 3 out of 7 resected patients were disease-free at a median follow-up of 2.9 years (range, 1.6-8.0 years). Conclusion Our experience confirms the importance of early correct diagnosis and of an R0 resection for a sacral chordoma invading pelvic structures. It is a rare disease that requires a challenging multidisciplinary treatment, which should ideally be performed in a tertiary referral center. PMID:24999463

Since 14 years of age, the patient had experienced extreme penile pain within seconds of initial sexual arousal through masturbation. Penile pain was so severe that he rarely proceeded to orgasm or ejaculation. After 7 years of undergoing multiple unsuccessful treatments, he was concerned for his long-term mental health and for his future ability to have relationships. To describe a novel collaboration among specialists in sexual medicine, neurophysiology, and spine surgery that led to successful management. Collaborating health care providers conferred with the referring physician, patient, and parents and included a review of all medical records. Elimination of postpubertal intense penile pain during sexual arousal. The patient presented to our sexual medicine facility at 21 years of age. The sexual medicine physician identifying the sexual health complaint noted a pelvic magnetic resonance imaging report of an incidental sacral Tarlov cyst. A subsequent sacral magnetic resonance image showed four sacral Tarlov cysts, with the largest measuring 18 mm. Neuro-genital testing result were abnormal. The neurophysiologist hypothesized the patient's pain at erection was produced by Tarlov cyst-induced neuropathic irritation of sensory fibers that course within the pelvic nerve. The spine surgeon directed a diagnostic injection of bupivacaine to the sacral nerve roots and subsequently morphine to the conus medullaris of the spinal cord. The bupivacaine produced general penile numbness; the morphine selectively decreased penile pain symptoms during sexual arousal without blocking penile skin sensation. The collaboration among specialties led to the conclusion that the Tarlov cysts were pathophysiologically mediating the penile pain symptoms during arousal. Long-term follow-up after surgical repair showed complete symptom elimination at 18 months after treatment. This case provides evidence that (i) Tarlov cysts can cause sacral spinal nerve root radiculitis through

We sought to compare recovery of activity and pain control after robotic (ROB) vs abdominal (ABD) sacral colpopexy. Women undergoing ROB and ABD sacral colpopexy wore accelerometers for 7 days preoperatively and the first 10 days postoperatively. They completed postoperative pain diaries and Short Form-36 questionnaires before and after surgery. At 5 days postoperatively, none of the 14 subjects in the ABD group and 4 of 28 (14.3%) in the ROB group achieved 50% total baseline activity counts (P = .283). At 10 days, 5 of 14 (35.7%) in the ABD group and 8 of 26 (30.8%) in the ROB group (P = .972) achieved 50%. Postoperative pain was similar in both groups. Short Form-36 vitality scores were lower (P = .017) after surgery in the ABD group, but not in the ROB group. Women undergoing ROB vs ABD sacral colpopexy do not recover physical activity faster, and pain control is not improved. Copyright © 2012 Mosby, Inc. All rights reserved.

Sacral agenesis is an uncommon congenital disorder that involves multiple organs. We studied neurological manifestations of the disease, common associated disorders, and their relation with extent of bony malformation. We investigated neurological manifestations of 50 patients with sacral agenesis. Patients were evaluated for previous procedures, ambulation, limb abnormalities, vertebral alignment, recurrent urinary tract infection, urinary incontinence, dribbling, dimple, lower extremities weakness, myelomeningocele (MMC), and lipomyelomenangocele. Weakness of lower extremities was seen in 37 (74%) patients. Concurrent weakness of proximal and distal muscles of the lower limb was statistically associated with a type of bony aplasia (P = .001). However, paraplegia was seen in only 2 of 44 children over the age of 1, and the rest could walk. Myelodysplastic syndromes were seen in 21 patients. Sacral agenesis is diagnosed in children with concomitant MMC at younger ages and reveals more severe symptoms. Progression of neurological disorders was seen in 19 patients, in all of whom MRI showed tethering of the spinal cord. Urinary disorders including diurnal urinary incontinence (in 30 of 35 children over age 4) and recurrent urinary tract infections (in 37) were also common. Imperforate anus was seen in 11 patients. Twelve children over age 4 reported fecal incontinence, a problem that had statistically significant association with imperforate anus (P = .013). Different disorders can concurrently affect patients with sacral agenesis that may have profound impressions on patients and their families. Early diagnosis, thorough evaluation, and proper intervention are of utmost importance as they can prevent or lessen future complications.

Morphological evaluation of the thoracic, lumbar and sacral column of the giant anteater (Myrmecophaga tridactyla Linnaeus, 1758

Full Text Available ABSTRACT: This study aimed to describe the number of thoracic, lumbar and sacral vertebrae in tridactyla through radiographic examinations associated with gross anatomy determination. For this purpose, 12 adult specimens of M. tridactyla were analyzed, assigned to the Screening Center of Wild Animals (CETAS, IBAMA-GO, and approved by the Ethics Committee on the Use of Animals (Process CEUA-UFG nr 018/2014. In the radiographic examinations the following numbers of thoracic (T and lumbar (L vertebrae were observed: 16Tx2L (n=7, 15Tx2L (n=3, and 15Tx3L (n=2. In contrast, the numbers of vertebrae identified by anatomical dissection were as follows: 16Tx2L (n=4, 15Tx2L (n=3, and 15Tx3L (n=5. This difference occurred in cases of lumbarization of thoracic vertebrae, as seen in three specimens, and was explained by changes in regional innervations identified by anatomical dissection and the presence of floating ribs (right unilateral=1, left unilateral=1 and bilateral=1, which were not identified by radiographic exams. Regarding the sacral vertebrae there was no variation depending on the methods used, which allowed the identification of 4 (n=1 or 5 (n=11 vertebrae. Thus, we concluded that there is variation in the number of thoracic, lumbar and sacral vertebrae, in addition to lumbarization, which must be considered based on the presence of floating ribs, in this species.

Full Text Available Abstract Background Percutaneous sacro-iliac (SI screw fixation represents a widely used technique in the management of unstable posterior pelvic ring injuries and sacral fractures. The misplacement of SI-screws under fluoroscopic guidance represents a critical complication for these patients. This study was designed to determine the prevalence of sacral dysmorphia and the radiographic anatomy of surgical S1 and S2 corridors in a representative trauma population. Methods Prospective observational cohort study on a consecutive series of 344 skeletally mature trauma patients of both genders enrolled between January 1, 2007, to September 30, 2007, at a single academic level 1 trauma center. Inclusion criteria included a pelvic CT scan as part of the initial diagnostic trauma work-up. The prevalence of sacral dysmorphia was determined by plain radiographic pelvic films and CT scan analysis. The anatomy of sacral corridors was analyzed on 3 mm reconstruction sections derived from multislice CT scan, in the axial, coronal, and sagittal plane. "Safe" potential surgical corridors at S1 and S2 were calculated based on these measurements. Results Radiographic evidence of sacral dysmorphia was detected in 49 patients (14.5%. The prevalence of sacral dysmorphia was not significantly different between male and female patients (12.2% vs. 19.2%; P = 0.069. In contrast, significant gender-related differences were detected with regard to radiographic analysis of surgical corridors for SI-screw placement, with female trauma patients (n = 99 having significantly narrower corridors at S1 and S2 in all evaluated planes (axial, coronal, sagittal, compared to male counterparts (n = 245; P P = 0.06, implying S2 as a safe surgical corridor of choice in patients with sacral dysmorphia. Conclusions These findings emphasize a high prevalence of sacral dysmorphia in a representative trauma population and imply a higher risk of SI-screw misplacement in female patients

Intraspinal navigation with catheters and fiberscopes has shown feasible results for diagnosis and treatment of intraspinal and intracranial lesions. The most common approach, lumbar puncture, has allowed access to the spinal cord, however, coming with the difficulties of fiberscope damage and decreased torque for guidance. Our objective in this study is to allow an alternate access, the sacral hiatus, with guide wire assistance into the subarachnoid and intracranial structures, while easing the angle of entry and increasing torque. We advanced catheters with guide wire and fluoroscopy assistance into the sacral hiatus of three cadavers. After entry, the thecal sac was punctured and the catheter with guide wire was advanced rostrally until positioned in the basal cisterns of the brain. We confirmed catheter placement with contrast injection, autopsy, and dissection. In our study, the sacral hiatus was easily accessed, but resistance was found when attempting to puncture the thecal sac. The advancement of the catheter with guide wire assistance glided easily rostrally until some mild resistance was discovered at entry into the foramen magnum. With redirection, all catheters passed with ease into the basal cisterns. Positioning was confirmed with contrast injection with fluoroscopy evidence, autopsy, and dissection. There was no macroscopic or microscopic evidence of damage to the spinal roots, spinal cord, or cranial nerves. The sacral hiatus with guide wire assistance is an accessible conduit for uncomplicated entry into the subarachnoid and basal cistern space without damaging surrounding structures.

Percutaneous sacro-iliac (SI) screw fixation represents a widely used technique in the management of unstable posterior pelvic ring injuries and sacral fractures. The misplacement of SI-screws under fluoroscopic guidance represents a critical complication for these patients. This study was designed to determine the prevalence of sacral dysmorphia and the radiographic anatomy of surgical S1 and S2 corridors in a representative trauma population. Prospective observational cohort study on a consecutive series of 344 skeletally mature trauma patients of both genders enrolled between January 1, 2007, to September 30, 2007, at a single academic level 1 trauma center. Inclusion criteria included a pelvic CT scan as part of the initial diagnostic trauma work-up. The prevalence of sacral dysmorphia was determined by plain radiographic pelvic films and CT scan analysis. The anatomy of sacral corridors was analyzed on 3 mm reconstruction sections derived from multislice CT scan, in the axial, coronal, and sagittal plane. "Safe" potential surgical corridors at S1 and S2 were calculated based on these measurements. Radiographic evidence of sacral dysmorphia was detected in 49 patients (14.5%). The prevalence of sacral dysmorphia was not significantly different between male and female patients (12.2% vs. 19.2%; P = 0.069). In contrast, significant gender-related differences were detected with regard to radiographic analysis of surgical corridors for SI-screw placement, with female trauma patients (n = 99) having significantly narrower corridors at S1 and S2 in all evaluated planes (axial, coronal, sagittal), compared to male counterparts (n = 245; P dysmorphia. These findings emphasize a high prevalence of sacral dysmorphia in a representative trauma population and imply a higher risk of SI-screw misplacement in female patients. Preoperative planning for percutaneous SI-screw fixation for unstable pelvic and sacral fractures must include a detailed CT scan analysis to determine

All components of the sacrum (bone, cartilage, bone marrow, meninges, nerves, notochord remnants, etc.) can give rise to benign or malignant tumours. Bone metastases and intraosseous sites of haematological malignancies, lymphoma and multiple myeloma are the most frequent aetiologies, while primary bone tumours and meningeal or nerve tumours are less common. Some histological types have a predilection for the sacrum, especially chordoma and giant cell tumour. Clinical signs are usually minor, and sacral tumours are often discovered in the context of nerve root or pelvic organ compression. The roles of conventional radiology, CT and MRI are described and compared with the histological features of the main tumours.

An anatomic and radiographic study of placement of sacroiliac screws. The aim of this study was to quantitatively assess the risk of partial cut-out of sacroiliac screws from the sacral ala slope via inlet and outlet view. The partial cut-out of sacroiliac screws from the superior surface of sacral ala can jeopardize the L5 nerve root, which is difficult to identify on the pelvic inlet and outlet views. Computed tomography images of 60 patients without pelvic ring deformity or injury were used to measure the width (on inlet view) and height (on outlet view) of the sacral ala. The angle of the sacral ala slope was measured on lateral view. According to the measured parameters, the theoretical safe trajectories of screw placement were calculated using inverse trigonometric functions. Under fluoroscopic guidance, a sacroiliac screw was placed close to the midline on both inlet and outlet views, including posterosuperior, posteroinferior, anterosuperior, and anteroinferior regions to the midline. The incidence of screw partial cut-out from the superior surface of sacral ala was identified. The measured widths and heights of the sacral alas were 28.1 ± 2.8 and 29.8 ± 3.1 mm, respectively. The average angle between the superior aspect of the S1 vertebral body and the superior aspect of the sacral ala was 37.2 ± 2.5 degrees. The rate of partial cut-out of the screws from the superior surface of sacral ala slope was 12.5% (5/40) in posterosuperior, 0% (0/40) in posteroinferior, 70% (28/40) in anterosuperior, and 20% (8/40) in anteroinferior. To avoid the risk of partial cut-out from sacroiliac screw placement, more precise description should be added to the conventional description: the sacroiliac screws should be placed at the inferior half portion on outlet view and at the posterior half portion on inlet view. 4.

Myeloradiculitis is a rare neurological complication of herpes simplex type 2 (HSV-2) infection, frequently associated with a fatal outcome. Among patients with HIV infection, HSV-2 myeloradiculitis has occasionally been reported, always associated with advanced immunosuppression and AIDS. We report a patient with HIV infection but no history of previous opportunistic infections, who developed sacral myeloradiculitis immediately after an episode of genital herpes. Magnetic resonance imaging with gadolinium showed necrotizing myelitis in the conus medullaris and enhancement of sacral roots. CD4 lymphocyte count was 530/mm3. Other possible causes of myeloradiculitis in HIV-infected patients were appropriately excluded. Acyclovir therapy resulted in partial clinical improvement. This report shows that myeloradiculitis as a complication of genital herpes may occur in the early stages of HIV infection and may have a favourable outcome with antiviral treatment.

Sacral pressure sore reconstruction – the pedicled superior gluteal ...

Pressure sore reconstruction has always been challenging. Immobile patients are prone to develop pressure sores from unre- lieved pressure on tissue over the sacral area, with shear, friction, moisture and malnutrition as contributing factors. Up to one-third of immobilised patients in long-term care facilities will develop.

Purpose: To evaluate the efficacy and safety of navigation-guided radiofrequency kyphoplasty for sacroplasty in patients with sacral insufficiency fractures. Methods: In this single-center retrospective observational study, four consecutive patients with sacral insufficiency fractures were treated with navigation-guided radiofrequency kyphoplasty for sacroplasty between April 2010 and May 2012. Symptom characteristics, pain duration and pain intensity were recorded for each patient. Cement extravasation was evaluated in thin-sliced and triplanar reconstructed CT scans of the sacrum. Results: Four female patients with painful sacral insufficiency fractures and extensive osteopenic areas significantly improved from an average pre-treatment VAS score of 8.3 {+-} 0.5 to 2.3 {+-} 1.0 (p < 0.001) on the first postoperative day and to 1.3 {+-} 1.9 (p < 0.004) at follow-up (mean, 20.1 weeks). Slight cement extravasations were observed without evidence of being symptomatic. No major complications or procedure-related morbidity were noted. Conclusion: From the limited experience in four patients, navigation-guided radiofrequency kyphoplasty appears to be a safe and effective treatment option for sacral insufficiency fractures even though asymptomatic cement extravasation was noted. The use of navigation based on intraoperative 3 D images simplifies the positioning of the navigated bone needles via the long axis approach. The radiofrequency kyphoplasty system provides the possibility to administer a sufficient amount of bone cement with a well-defined viscosity over the entire period of the procedure leading to high security and low cement extravasation. Sacroplasty provides rapid and enduring pain relief and facilitates prompt mobilization. (orig.)

Following radiation therapy, marrow abnormalities noted on magnetic resonance imaging (MRI) are frequent and may mimic metastases. Specific radiotherapy changes are usually easily identifiable; however, traumatic lesions cause more interpretive difficulties. We assessed the incidence and MRI characteristics of insufficiency fractures in this population. During a 5-year span (1987-1991), 546 patients received pelvic radiotherapy for primary malignancies. MRI was performed in 25 of these patients at least 3 months after treatment. The mean dose in this group was 53 Gy. These MRI scans were retrospectively reviewed for the appearance of the sacrum with particular attention to the presence of insufficiency fractures. This was correlated with clinical course and scintigraphic findings. Presumed insufficiency fractures on MRI paralleled the sacral side of the sacroiliac joint, enhanced with Gd-DTPA, were most prominent or initially seen anteriorly, and had ill-defined margins on all imaging sequences. The incidence of occult sacral insufficiency fractures was at least 20%. Insufficiency fractures of the sacrum in the post-radiotherapy patient are a relatively frequent occurrence which can mimic metastases. Consideration of this phenomenon and knowledge of differential features may avoid overdiagnosis of osseous metastases. (orig.)

Spatial Narrative As Feature Of Singularity In Sacral Architecture

Full Text Available The paper analyses architectural compositions of various religious complexes – historical and contemporary – apart from their stylistic features. The most prominent ensembles under analysis have one noticeably common feature – spatial narrative. The foreseen sequence of forms of experience and spatial structure tell different religious narratives depending on which different aspects of faith were actualized in a given period. The analyzed examples stand in proof that suggestibility of religious aspects in sacral architecture are inseparable from their artistic suggestibility aspects. In some cases, these aspects are less related to architectural stylistic means, but have a direct connection to such components of architectural compositions as foreseen sequence of a visitor’s experience and semantics of particular forms, i.e. architectural narrative, which is achieved not only through the means of perception of space, but also by the relationship to social and cultural meanings and subtext of architecture.

The efficacy of sacral nerve stimulation in faecal incontinence relies on an implanted pulse generator known to have a limited lifespan. The long-term use of sacral nerve stimulation raises concerns about the true lifespan of generators. The aim of the study was to assess the lifespan of sacral nerve stimulation implanted pulse generators in daily practice, and the outcome of exhausted generator replacement, in faecal incontinent patients. Faecal incontinent patients with pulse generators (Medtronic Interstim™ or InterstimII™) implanted in a single centre from 2001 to 2014 were prospectively followed up. Generator lifespan was measured according to the Kaplan-Meier method. Patients with a generator explanted/turned off before exhaustion were excluded. Morbidity of exhausted generator replacement and the outcome (Cleveland Clinic Florida Faecal Incontinence (CCF-FI) and Faecal Incontinence Quality of Life (FIQL) scores) were recorded. Of 135 patients with an implanted pulse generator, 112 (InterstimII 66) were included. Mean follow-up was 4.9 ± 2.8 years. The generator reached exhaustion in 29 (26%) cases. Overall median lifespan of an implanted pulse generator was approximately 9 years (95% CI 8-9.2). Interstim and InterstimII 25th percentile lifespan was 7.2 (CI 6.4-8.3) and 5 (CI 4-not reached) years, respectively. After exhaustion, generators were replaced, left in place or explanted in 23, 2 and 4 patients, respectively. Generator replacement was virtually uneventful. CCF-FI/FIQL scores remained unchanged after generator replacement (CCF-FI 8 ± 2 vs 7 ± 3; FIQL 3 ± 0.6 vs 3 ± 0.5; p = ns). In this study, the implanted pulse generator observed median lifespan was 9 years. After exhaustion, generators were safely and efficiently replaced. The study also gives insight into long-term needs and costs of sacral nerve stimulation (SNS) therapy.

Seven healthy volunteers underwent coronal MR imaging at 1.5 tesla of the normal 3rd, 4th, and 5th lumbar, and 1st sacral nerve roots. Coronal slices, 3-mm-thick with a 0.3-mm gap between the slices were obtained (TR/TE 600/22) through the lumbar spinal canal. All the nerve roots were visible on at least one image. One can routinely expect to demonstrate the 3rd, 4th, and 5th lumbar, and 1st sacral nerve roots on T1-weighted, 3-mm-thick coronal MR scans. We found no correlation between the degree of lumbar lordosis and the lengths of the visible nerve roots. Five patients with one of the following spinal problems: anomaly, tumor, disk herniation, and failed back surgery syndrome were examined according to our protocol. In all these cases coronal MR imaging gave the correct diagnosis. (orig.)

The sacral autonomic outflow is parasympathetic: Langley got it right.

Science.gov (United States)

Horn, John P

2018-04-01

A recent developmental study of gene expression by Espinosa-Medina, Brunet and colleagues sparked controversy by asserting a revised nomenclature for divisions of the autonomic motor system. Should we re-classify the sacral autonomic outflow as sympathetic, as now suggested, or does it rightly belong to the parasympathetic system, as defined by Langley nearly 100 years ago? Arguments for rejecting Espinosa-Medina, Brunet et al.'s scheme subsequently appeared in e-letters and brief reviews. A more recent commentary in this journal by Brunet and colleagues responded to these criticisms by labeling Langley's scheme as a historical myth perpetuated by ignorance. In reaction to this heated exchange, I now examine both sides to the controversy, together with purported errors by the pioneers in the field. I then explain, once more, why the sacral outflow should remain known as parasympathetic, and outline suggestions for future experimentation to advance the understanding of cellular identity in the autonomic motor system.

Sacral Herpes Zoster Associated with Voiding Dysfunction in a Young Patient with Scrub Typhus.

Hur, Jian

2015-06-01

When a patient presents with acute voiding dysfunction without a typical skin rash, it may be difficult to make a diagnosis of herpes zoster. Here, we present a case of scrub typhus in a 25-year-old man with the complication of urinary dysfunction. The patient complained of loss of urinary voiding sensation and constipation. After eight days, he had typical herpes zoster eruptions on the sacral dermatomes and hypalgesia of the S1-S5 dermatomes. No cases of dual infection with varicella zoster virus and Orientia tsutsugamushi were found in the literature. In the described case, scrub typhus probably induced sufficient stress to reactivate the varicella zoster virus. Early recognition of this problem is imperative for prompt and appropriate management, as misdiagnosis can lead to long-term urinary dysfunction. It is important that a diagnosis of herpes zoster be considered, especially in patients with sudden onset urinary retention.

Kinesio Taping (KT) is a therapeutic method used by physical therapists and athletic trainers in combination with other treatment techniques for various musculoskeletal and neuromuscular problems. However, no research has evaluated the effect of KT in patients with low back pain (LBP). The purpose of this case was to describe the application of posterior pelvic tilt taping (PPTT) with Kinesio tape as a treatment for chronic LBP and to reduce the anterior pelvic tilt angle. Case report. The patien was a 20-year-old female amateur swimmer with a Cobb's angle (L1-S1) of 68°, a sacral horizontal angle of 45°, and pain in both medial buttock areas and sacroiliac joints. We performed PPTT with Kinesio tape for 2 weeks (six times per week for an average of 9 h each time). The patient’s radiographs showed that the Cobb's angle (L1-S1) had decreased from 68° to 47° and that the sacral horizontal angle had decreased from 45° to 31°. Reductions in hypomobility or motion asymmetry, as assessed by the motion palpation test, and in pain, as measured by the pain-provocation tests, were observed. On palpation for both medial buttock areas in the prone position, the patient felt no pain. The patient experienced no pain or stiffness in the low back area while performing forward flexion in the standing position with knees fully extended when washing dishes in the sink. The case study demonstrated that PPTT intervention favourably affected the pelvic inclination and sacral horizontal angle, leading to beneficial effects on sacroiliac joint dysfunction (SIJD) and medial buttock pain. Additional research on the clinical effects of this taping procedure requires greater numbers of athletes with SIJD or LBP who have inappropriate anterior pelvic tilt angles and hyperlordosis.

To determine the association between a greater rostral projection of the sacral lamina and clinical signs of cauda equina syndrome (CES) in German shepherd dogs (GSD) with presumptive degenerative lumbosacral disease (DLSS). Retrospective cohort study. One hundred forty-three GSD (125 police dogs and 18 pet dogs) presenting for either CES or prebreeding evaluation. Fifty-five were classified as affected by CES and diagnosed with DLSS, and 88 were classified as unaffected on the basis of clinical and imaging findings. The position of the rostral edge of the sacral lamina was measured from radiographs and/or computed tomography (CT) scans. This position was compared between affected and unaffected dogs. In dogs that underwent both radiography and CT scanning, the agreement between sacral lamina localization using each imaging modality was determined. Owners/handlers were contacted to determine whether dogs subsequently developed clinical signs compatible with CES at a mean of 29 months (unaffected). The sacral lamina did not extend as far rostrally in affected dogs, compared to unaffected dogs (P = .04). Among the 88 dogs unaffected by CES at initial evaluation, 2 developed clinical signs consistent with CES at follow-up. Rostral projection of the sacral lamina, previously proposed as a potential risk factor in dogs with CES due to lumbosacral degeneration, was not associated with a diagnosis of DLSS in this study; the opposite was true. Rostral projection of the sacral lamina may not be a predisposing factor in the development of CES due to DLSS in GSD. © 2018 The American College of Veterinary Surgeons.

Sacral Theater has been developed for the toroid magnet Atlas of the CERN LHC project. This three dimensional calculations code calculates the propagation of the transition of a superconducting coil in 25 m long hippodrome. Procedures to study low currents have been included. This work is a part of the magnet safety system because the coils protection is made by warmers activating the quench propagation in case of default detection. This allows the complete dissipation of storage energy that can reach 1080 MJ on Atlas. (N.C.)

Tarlov cyst: Case report and review of literature

Prashad Bhagwat

2007-01-01

Full Text Available We describe a case of sacral perineural cyst presenting with complaints of low back pain with neurological claudication. The patient was treated by laminectomy and excision of the cyst. Tarlov cysts (sacral perineural cysts are nerve root cysts found most commonly in the sacral roots, arising between the covering layer of the perineurium and the endoneurium near the dorsal root ganglion. The incidence of Tarlov cysts is 5% and most of them are asymptomatic, usually detected as incidental findings on MRI. Symptomatic Tarlov cysts are extremely rare, commonly presenting as sacral or lumbar pain syndromes, sciatica or rarely as cauda equina syndrome. Tarlov cysts should be considered in the differential diagnosis of patients presenting with these complaints.

The method of free-hand pedicle screw placement is generally safe although it carries potential risks. For this reason, several highly accurate computer-assisted systems were developed and are currently on the market. However, these devices have certain disadvantages. We have developed a method of pedicle screw placement in the lumbar and sacral region using a multi-level drill guide template, created with the rapid prototyping technology and have validated it in a clinical study. The aim of the study was to manufacture and evaluate the accuracy of a multi-level drill guide template for lumbar and first sacral pedicle screw placement and to compare it with the free-hand technique under fluoroscopy supervision. In 2011 and 2012, a randomized clinical trial was performed on 20 patients. 54 screws were implanted in the trial group using templates and 54 in the control group using the fluoroscopy-supervised free-hand technique. Furthermore, applicability for the first sacral level was tested. Preoperative CT-scans were taken and templates were designed using the selective laser sintering method. Postoperative evaluation and statistical analysis of pedicle violation, displacement, screw length and deviation were performed for both groups. The incidence of cortex perforation was significantly reduced in the template group; likewise, the deviation and displacement level of screws in the sagittal plane. In both groups there was no significantly important difference in deviation and displacement level in the transversal plane as not in pedicle screw length. The results for the first sacral level resembled the main investigated group. The method significantly lowers the incidence of cortex perforation and is therefore potentially applicable in clinical practice, especially in some selected cases. The applied method, however, carries a potential for errors during manufacturing and practical usage and therefore still requires further improvements.

Purpose: Develop an IMRT planning technique that can preferentially spare sacral bone marrow for pelvic cancer patients. Methods: Six pelvic cancer patients (two each with anal, cervical, and rectal cancer) were enrolled in an IRB approved protocol to obtain FLT PET images at simulation, during, and post chemoradiation therapy. Initially, conventional IMRT plans were created to maintain target coverage and reduce dose to OARs such as bladder, bowel, rectum, and femoral heads. Simulation FLT PET images were used to create IMRT plans to spare bone marrow identified as regions with SUV of 2 or greater (IMRT-BMS) within the pelvic bones from top of L3 to 5mm below the greater trochanter without compromising PTV coverage or OAR sparing when compared to the initial IMRT plan. IMRT-BMS plans used 8–10 beam angles that surrounded the subject. These plans were used for treatment. Retrospectively, the same simulation FLT PET images were used to create IMRT plans that spared bone marrow located in the sacral pelvic bone region (IMRT-FAN) also without compromising PTV coverage or OAR sparing. IMRT-FAN plans used 16 beam angles every 12° anteriorly from 90° – 270°. Optimization objectives for the sacral bone marrow avoidance region were weighted to reduce ≥V10. Results: IMRT-FAN reduced dose to the sacral bone marrow for all six subjects. The average V5, V10, V20, and V30 differences from the IMRT-BMS plan were −2.2 ± 1.7%, −11.4 ± 3.6%, −17.6 ± 5.1%, and −19.1 ± 8.1% respectively. Average PTV coverage change was 0.5% ± 0.8% from the conventional IMRT plan. Conclusion: An IMRT planning technique that uses beams from the anterior and lateral directions reduced the volume of sacral bone marrow that receives ≤10Gy while maintaining PTV coverage and OAR sparing. Additionally, the volume of sacral bone marrow that received 20 or 30 Gy was also reduced.

Patients aged 75 years and older with blunt pelvic trauma are frequently seen in the ER. The standard diagnostic tool in these patients is the plain a.p.-radiograph of the pelvis. Especially lesions of the posterior pelvic ring are often missed due to e.g. bowel gas projection and enteric overlay. With a retrospective study covering these patients over a 3 year period in our level I trauma centre, we were able to evaluate the rate of missed injuries in the a.p.-radiograph whenever a corresponding CT scan was performed. Age, gender, and accompanying fractures of the pelvic ring were recorded. The intrinsic test characteristics and the performance in the population were calculated according to standard formulas. Thus, 233 consecutive patients with blunt pelvic trauma with both conventional radiographic examination and computed tomography (CT) were included. Thereof, 56 (23%) showed a sacral fracture in the CT scan. Of 233 pelvic X-ray-images taken, 227 showed no sacral fracture. 51 (21.7%) of these were false negative, yielding a sensitivity of just 10.5%. Average age of patients with sacral fractures was 85.1±6.1 years, with 88% being female. Sacral fractures were often accompanied by lesions of the anterior pelvic ring with pubic bone fractures in 75% of sacrum fracture cases. Second most concomitant fractures are found at the acetabulum (23.3%). Plain radiographic imaging is especially likely to miss out fractures of the posterior pelvic ring, which nowadays can be of therapeutic consequence. Besides the physicians experience in the ED, profound knowledge of insensitivity of plain radiographs in finding posterior pelvic ring lesions is crucial for a reliable diagnostic routine. Since the high mortality caused by prolonged immobilisation due to pelvic ring injuries, all fractures should be identified. We therefore provide a diagnostic algorithm for blunt pelvic trauma in the elderly. Copyright © 2016 Elsevier Ltd. All rights reserved.

Isolated Transverse Sacrum Fracture: A Case Report

Directory of Open Access Journals (Sweden)

Cemil Kavalci

2011-01-01

Full Text Available Sacral fracture commonly results from high-energy trauma. Most insufficiency fractures of the sacrum are seen in women after the age of 70. Fractures of the sacrum are rare and generally combined with a concomitant pelvic fracture. Transverse sacral fractures are even less frequent which constitute only 3–5% of all sacral fractures. This type of fractures provide a diagnostic challenge. We report a unique case of isolated transverse fracture of sacrum in a young man sustained low-energy trauma. The patient presented to our emergency department after several hours of injury, and diagnosed by clinical features and roentgenogram findings.

Full thickness colonic prolapse following pseudocontinent perineal colostomy has not been previously reported. Possible contributing factors include a large skin aperture at the site of the perineal stoma, the absence of anal sphincters and mesorectal attachments and the presence of a perineal hernia. A novel application of sacral pexy combined with perineal hernia repair using two prosthetic meshes is described.

[Sacral neuromodulation in urology - development and current status].

Science.gov (United States)

Schwalenberg, T; Stolzenburg, J-U; Kriegel, C; Gonsior, A

2012-01-01

Sacral neuromodulation (SNM) in urology is employed to treat refractory lower urinary tract dysfunction as well as chronic pelvic pain. Electrical stimulation of the sacral afferents (S2 - S4) causes activation and conditioning of higher autonomic and somatic neural structures and thereby influences the efferents controlling the urinary bladder, the rectum and their related sphincter systems. It is therefore possible to treat overactivity as well as hypocontractility and functional bladder neck obstruction. SNM treatment is conducted biphasically. Initially, test electrodes are placed to evaluate changes in micturition and pain parameters. If, in this first phase - called peripheral nerve evaluation (PNE test) - sufficient improvements are observed, the patient progresses to phase two which involves implantation of the permanent electrodes and impulse generator system. In recent years, the "two stage approach" with initial implantation of the permanent electrodes has been favoured as it increases treatment success rates. Long-term success rates of SNM vary significantly in the literature (50 - 80 %) due to heterogeneous patient populations as well as improved surgical approaches. With the introduction of "tined lead electrodes" (2002), tissue damage is reduced to a minimum. Technical innovation, financial feasibility (reimbursed in Germany since 2004) and wider application, especially in otherwise therapy-refractory patients or complex dysfunctions of the pelvis, have established SNM as a potent treatment option in urology. © Georg Thieme Verlag KG Stuttgart · New York.

Disabling Orthostatic Headache after Penetrating Stonemason Pencil Injury to the Sacral Region

Directory of Open Access Journals (Sweden)

Carlo Brembilla

2015-01-01

Full Text Available Penetrating injuries to the spine, although less common than motor vehicle accidents and falls, are important causes of injury to the spinal cord. They are essentially of two varieties: gunshot or stab wounds. Gunshot injuries to the spine are more commonly described. Stab wounds are usually inflicted by knife or other sharp objects. Rarer objects causing incidental spinal injuries include glass fragments, wood pieces, chopsticks, nailguns, and injection needles. Just few cases of penetrating vertebral injuries caused by pencil are described. The current case concerns a 42-year-old man with an accidental penetrating stonemason pencil injury into the vertebral canal without neurological deficit. After the self-removal of the foreign object the patient complained of a disabling orthostatic headache. The early identification and treatment of the intracranial hypotension due to the posttraumatic cerebrospinal fluid (CSF sacral fistulae were mandatory to avoid further neurological complications. In the current literature acute pattern of intracranial hypotension immediately after a penetrating injury of the vertebral column has never been reported.

Imaging Findings of Pelvic Tumor Thrombosis Extending from Sacral Bone Metastasis of Adrenocortical Carcinoma

Directory of Open Access Journals (Sweden)

Kenichiro Ishida

2012-01-01

Full Text Available We report the imaging findings of a patient with adrenocortical carcinoma who showed pelvic tumor thrombosis extending from sacral bone metastasis. Contrast-enhanced computed tomography demonstrated extensive intraluminal filling defects in the pelvic veins. A lytic lesion in the sacrum was also noted and continuity between the sacral lesion and the filling defect in the branch of pelvic veins was indicated. The filling defects showed increased uptake on positron emission tomography with 18F-fluorodeoxyglucose and single-photon emission computed tomography with 131I-iodomethylnorcholesterol, and fusion images with computed tomography aided the localization of the increased uptake areas. Multimodality imaging may be beneficial for the characterization and localization of lesions in patients suspected of having metastatic adrenocortical carcinoma.

We have treated 5 cases of sacral radiation ulcer surgically. All patients with cervical or vulval cancer were treated with external radiotherapy more than 20 years ago. Three patients have rectovaginal fistulas and four patients have osteoradionecrosis of the sacrum. Fecal and/or urinary diversion were accomplished preoperatively in four patients. After debridement of ulcers, these defects were covered by pedicled musculocutaneous flaps. In two of five, marginal necrosis was seen in a great saphenous veno-neuro accompanying artery fasciocutaneous flap and an inferior gluteus maximus musculocutaneous flap. In two of five, seroma was seen. One patient died of the sepsis from pelvic infection with rectal fistula. Among the other four patients, there was no recurrence during the follow up period. The principle for surgically treating radiation ulcer is to completely resect all radionecrotic tissues and cover these defects with well vascularized tissues. It is useful to distinguish damaged tissue from health tissue by MRI. In a case having a rectovaginal fistula, it is recommended that fecal and urinary diversion will be done at first and debridement of ulcer and reconstructive surgery will be done later. (author)

Neurostimulation for bladder evacuation: is sacral root stimulation a substitute for microstimulation?

Science.gov (United States)

Probst, M; Piechota, H J; Hohenfellner, M; Gleason, C A; Tanagho, E A

1997-04-01

To determine by anatomical and functional studies whether stimulation of sacral rootlets might permit selective stimulation of autonomic fibres, thus avoiding the detrusor/sphincter dyssynergia characteristic of current techniques of neurostimulation for bladder evacuation. In 10 male mongrel dogs, the S2 root was isolated and its constituent rootlets followed from their origin in the spinal cord to the point of exit from the dura. The entire root and the individual rootlets were then stimulated, including intra- and extra-dural stimulation and at proximal, mid and distal levels. Neuroanatomical and histological findings showed that rootlets of ventral S2 maintain their identity throughout their intradural course; some carry predominantly autonomic fibres, some predominantly somatic and some a mixture of the two. It appears surgically feasible to identify, isolate and sever the predominantly somatic rootlets intradurally, sparing the predominantly autonomic rootlets for inclusion in extradural electrode placement around the entire sacral root, thus eliminating sphincteric interference with detrusor contraction for voiding at low pressure.

Electrical sacral nerve root stimulation can be used in spinal cord injury patients to induce urinary bladder contraction. However, existing stimulation methods activate simultaneously both the detrusor muscle and the urethral sphincter. Urine evacuation is therefore only possible using poststimulus

Sacral Fracture Nonunion Treated by Bone Grafting through a Posterior Approach

Directory of Open Access Journals (Sweden)

Sang Yang Lee

2013-01-01

Full Text Available Nonunion of a sacral fracture is a rare but serious clinical condition which can cause severe chronic pain, discomfort while sitting, and significant restriction of the level of activities. Fracture nonunions reportedly occur most often after nonoperative initial treatment or inappropriate operative treatment. We report a case of fracture nonunion of the sacrum and pubic rami that resulted from non-operative initial treatment, which was treated successfully using bone grafting through a posterior approach and CT-guided percutaneous iliosacral screw fixation combined with anterior external fixation. Although autologous bone grafting has been the gold standard for the treatment of pelvic fracture nonunions, little has been written describing the approach. We utilized a posterior approach for bone grafting, which could allow direct visualization of the nonunion site and preclude nerve root injury. By this procedure, we were able to obtain the healing of fracture nonunion, leading to pain relief and functional recovery.

Retrospective study. To report on neuromuscular patients with preserved walking ability, but forward bending of the body due to thoracic lordosis, and to suggest thoracic lordosis correction as the surgical treatment. It is an established fact that lumbar lordosis or pelvic parameter is directly related to thoracic sagittal balance. However, the reverse relationship has not been fully defined yet. Loss of thoracic kyphosis results in positive sagittal balance, which causes walking difficulty. Neuromuscular patients with thoracic lordosis have not been reported yet, and there have been no reports on their surgical treatments. This study analyzed 8 patients treated with thoracic lordosis correction surgery. Every patient was diagnosed with muscular dystrophy. In thoracic lordosis correction surgery, anterior release was performed in the first stage and posterior segmental instrumentation was performed in the second stage. Radiographic parameters were compared and walking ability was evaluated with gait analysis. All patients were classified according to the modified Rancho Los Amigos Hospital system preoperatively and 2 years postoperatively to evaluate functional ability. The average follow-up period was 2.9 years. Before surgery, the mean thoracic sagittal alignment was -2.1-degree lordosis, the mean Cobb angle and sacral slope increased to 36.3 and 56.6 degrees, respectively. The anterior pelvic tilt in gait analysis was 29.3 degrees. At last follow-up after surgery, the mean thoracic sagittal alignment changed to 12.6-degree kyphosis, and the Cobb angle and sacral slope decreased to 18.9 and 39.5 degrees, respectively. Lumbar lordosis and the sacral slope showed significant positive correlation (Plordosis showed a significant correlation to the preoperative flexibility of the major curve (P=0.028). The anterior pelvic tilt in gait analysis improved to 15.4 degrees. The functional ability improved in 2 (50%) of 4 patients in class 2 and maintained in remaining 6

This study evaluated the relationship between the morphology of the sacrum-the sole bony link between the tail or coccyx and the rest of the body-and tail length (including presence/absence) and function using a comparative sample of extant mammals spanning six orders (Primates, Carnivora, Rodentia, Diprotodontia, Pilosa, Scandentia; N = 472). Phylogenetically-informed regression methods were used to assess how tail length varied with respect to 11 external and internal (i.e., trabecular) bony sacral variables with known or suspected biomechanical significance across all mammals, only primates, and only non-primates. Sacral variables were also evaluated for primates assigned to tail categories ('tailless,' 'nonprehensile short-tailed,' 'nonprehensile long-tailed,' and 'prehensile-tailed'). Compared to primates with reduced tail lengths, primates with longer tails generally exhibited sacra having larger caudal neural openings than cranial neural openings, and last sacral vertebrae with more mediolaterally-expanded caudal articular surfaces than cranial articular surfaces, more laterally-expanded transverse processes, more dorsally-projecting spinous processes, and larger caudal articular surface areas. Observations were corroborated by the comparative sample, which showed that shorter-tailed (e.g., Lynx rufus [bobcat]) and longer-tailed (e.g., Acinonyx jubatus [cheetah]) non-primate mammals morphologically converge with shorter-tailed (e.g., Macaca nemestrina) and longer-tailed (e.g., Macaca fascicularis) primates, respectively. 'Prehensile-tailed' primates exhibited last sacral vertebrae with more laterally-expanded transverse processes and greater caudal articular surface areas than 'nonprehensile long-tailed' primates. Internal sacral variables performed poorly compared to external sacral variables in analyses of extant primates, and were thus deemed less useful for making inferences concerning tail length and function in extinct primates.

To determine if laparoscopic sacral colpopexy (LSC) offers better apical support with a lower exposure rate than transvaginal mesh surgery with Elevate™. This was a retrospective cohort study comparing patients with apical prolapse (POP-Q point C ≥ -1) who underwent Elevate™ mesh repair (n = 146) with patients who underwent laparoscopic sacral colpopexy (n = 267). The sacral colpopexy group had a mean age of 59 years and a BMI of 25.7. Patients in the Elevate™ group were older, with a mean age of 63 and a BMI of 26.3. Most of the patients of both groups presented with pelvic organ prolapse stage III (LSC 73.8% and Elevate™ 87.0%) and their mean POP-Q point C were not significantly different (LSC 1.4 vs Elevate™ 1.2 cm). Operative time was longer in the LSC group (113 vs 91 min, p < 0.001), but estimated blood loss was lower (75 cm 3 vs 137 cm 3 , p < 0.001). No difference in mesh exposure rate could be found between the two groups at one year (Elevate™ 0.7% vs LSC 2.6%, OR 0.26, 95% CI 0.03 to 2.10, p = 0.21). One-year objective cure rate, defined as no descent beyond the hymen, was 97.0% in the LSC group and 96.6% in the Elevate™ group (p = .81). The overall recurrence (objective, subjective recurrence or reoperation) was also not different between the groups (LSC 4.5% vs Elevate 4.8%, p = 0.89). Transvaginal Elevate™ mesh delivers comparable apical support with a low exposure rate similar to that of laparoscopic sacral colpopexy.

Joubert et al. first reported a familial syndrome which showed episodic tachypena, abnormal eye movement, mental and motor retardation. Since then eighteen cases have been reported in the world. In this paper, we reported a male baby with Joubert syndrome who was observed since the newborn period. He showed episodic tachypnea (respiratory rate over 100/min), apnea, severe mental and motor retardation, no normal eye movements, occipital meningocele, high arched palate and poor sucking. CT scan revealed vermian agenesis, hypoplasia and deformity of brainstem, enlarged fourth ventricle and cisterna magna. EEG showed episodic discharges. Laboratory test investigations including amino acids, lactate, pyruvate, ammonia, chromosomal analysis, IVP and renogram showed no abnormal findings. He showed poor development and at eleventh month of age he died at home because of respiratory arrest. Similar syndromes were reported by Koya et al., Dekaban, Gardner et al., D'Agostino et al. and Friede. They reported syndromes consisting of abnormal respiration, abnormal eye movements, mental and motor retardation, occipital meningocele, retinal degeneration and polycystic kidney. Some causative events may have occurred at 6 to 7 weeks of gestation affecting central nervous system as well as other organs.

Characterization of herpes simplex virus type 2 latency-associated transcription in human sacral ganglia and in cell culture.

1991-01-01

The ability of herpes simplex virus type 2 (HSV-2) to establish latency in and reactivate from sacral dorsal root sensory ganglia is the basis for recurrent genital herpes. The expression of HSV-2 genes in latently infected human sacral ganglia was investigated by in situ hybridization. Hybridizations with a probe from the long repeat region of HSV-2 revealed strong nuclear signals overlying neurons in sacral ganglia from five of nine individuals. The RNA detected overlaps with the transcript for infected cell protein O but in the opposite, or "anti-sense," orientation. These observations mimic those made previously with HSV-1 in human trigeminal ganglia and confirm the recent findings during latency in HSV-2-infected mice and guinea pigs. Northern hybridization of RNA from infected Vero cells showed that an HSV-2 latency-associated transcript was similar in size to the larger (1.85 kb) latency transcript of HSV-1. Thus, HSV-1 and HSV-2 latency in human sensory ganglia are similar, if not identical, in terms of their cellular localization and pattern of transcription.

In patients with huge leiomyoma and with adenomyosis of the uterus, a peculiar area of hypointensity was occasionally observed on postcontrast magnetic resonance (MR) imaging in the dorsal portion of the enlarged uterus near the sacral promontory. We describe the imaging characteristics of these MR findings and correlate them with histopathological findings to examine whether the areas represent specific pathological changes. Ten patients with huge leiomyomas and two with huge adenomyotic lesions whose imaging revealed the hypointensity were enrolled. All had enlarged uteri that extended beyond the sacral promontory. MR findings of the hypointense areas were evaluated and correlated with histopathological findings in 5 patients with leiomyoma and two with adenomyosis who had hysterectomy. The ten patients with leiomyoma showed flare-shaped hypointensity arising from the dorsal surface of the uterine body that extended deep into the tumor. The base of the hypointense areas was narrow in 5 patients with intramural leiomyoma and broad in five with subserosal leiomyoma. Two patients with adenomyosis showed nodular-shaped areas of hypointensity in front of the sacral promontory. Precontrast T 1 - and T 2 -weighted MR images showed no signal abnormalities in the portions corresponding to the hypointensity in any of the 12 patients. Pathological examinations showed no specific findings in the portions corresponding to the hypointensity in the 7 patients who had hysterectomy. The areas of hypointensity may represent functional changes, such as decreased localized blood flow caused by compression of the sacral promontory. (author)

Acute herpes-zoster infection is a painful dermatomal lesion that can be manifested by a wide array of neurologic symptoms. We present a 55-year-old female with non-Hodgkin's lymphoma, who developed a left sciatic pain involving the S roots. Two weeks later, the patient developed fever and vesicular rash over the left gluteal area. Herpes-zoster infection was diagnosed and confirmed by the presence of immunoglobulin M (IgM) antibodies against varicella-zoster. The pain and rash resolved, after treatment with acyclovir. In the appropriate clinical setting, sacral herpes-zoster infection ought to be considered in the differential diagnosis of new-onset sciatic pain.

A butterfly vertebra is a rare congenital anomaly, encountered as isolated finding or as part of syndromic diseases. We report a case of a 40-year- old female presenting with low back pain and sciatica due to 'butterfly' dysplasia of the first sacral vertebra. This novel case includes posterolateral displacement of the completely separated hemivertebrae, causing left lateral recess stenosis and compression of S1 nerve root. Additionally, we conducted a short review of the literature. Few cases are reported in literature. Only one refers to a sacral vertebra. There is no previous case of a butterfly vertebra that accounts for narrowing of the lateral recess and associated radiculopathy.

Ten-year experience of superior gluteal artery perforator flap for reconstruction of sacral defects in Tri-Service General Hospital

Directory of Open Access Journals (Sweden)

Chin-Ta Lin

2014-01-01

Full Text Available Background: Despite advances in reconstruction techniques, sacral sores continue to present a challenge to the plastic surgeon. The superior gluteal artery perforator (SGAP flap is a reliable flap that preserves the entire contralateral side as a future donor site. On the ipsilateral side, the gluteal muscle itself is preserved and all flaps based on the inferior gluteal artery are still possible. However, the dissection of the perforator is tedious and carries a risk of compromising the perforator vessels. Patients and Methods: During the period between April 2003 and March 2013, 30 patients presented to our section with sacral wounds causing by pressure sores or infected pilonidal cysts. Of a total of 30 patients, 13 were female and 17 were male. Their ages ranged from 22 to 92 years old (mean 79.8 years old. Surgical intervention was performed electively with immediate or delayed reconstruction using a SGAP flap. The characteristics of patients′ age, and sex, and cause of sacral defect, co-morbidities, wound culture, flap size, perforator number, hospital stay, and outcome were reviewed. Results: For all operations, the length of the pedicle dissection will not exceed 1 cm because of the vascular anatomy of the SGAP, which lies adjacent to the sacral region. Due to short pedicle dissection, all SGAP flap were elevated around an hour. All flaps survived except two, which had partial flap necrosis and were finally treated by contralateral V-Y advancement flaps coverage. The mean follow-up period was 14.8 months (range 3-24. No flap surgery-related mortality was found. Conclusion: Perforator-based flaps have become popular in modern reconstructive surgery because of low donor site morbidity and good preservation of muscle. Our study shows that deep pedicle dissection is unnecessary when the surgery involves an accurate indicating perforator, adequate flap size design, and correct selection of flap utilization between tunnel and rotation.

The median age was 66 years. The highest proximal invasion reached past S2 level in 137 patients. The median clinical target volume was 345 cm{sup 3}. One hundred six patients received 67.2 gray equivalents (GyE)/16 fractions (fr), 74 patients received 70.4 GyE/16 fr, 7 patients received 73.6 GyE/16 fr, and 1 patient received 64.0 GyE/16 fr. Results: The median follow-up period was 62 months (range, 6.8-147.5 months). Seventy percent of patients were followed for 5 years or until death. The 5-year local control, overall survival, and disease-free survival rates were 77.2%, 81.1%, and 50.3%, respectively. Forty-one patients had a local recurrence. Sex, tumor volume, level of proximal invasion, and irradiated dose were unrelated to local control. There was grade 3 toxicity of the peripheral nerves in 6 patients and grade 4 toxicity of the skin in 2 patients. Ambulation remained in 97% of patients. Conclusions: Carbon ion radiation therapy was safe and effective for unresectable chordoma and provided good local control and survival while preserving ambulation.

The goal of this paper is to access to pelvis position and morphology in standing posture and to determine the relative locations of their articular surfaces. This is obtained from coupling bi planar radiography and bone modeling. The technique involves different successive steps. Punctual landmarks are first reconstructed, in space, from their projected images, identified on two orthogonal standing X-rays. Geometric models, of global pelvis and articular surfaces, are determined from punctual landmarks. The global pelvis is represented as a triangle of summits: the two femoral head centers and the sacral plateau center. The two acetabular cavities are modeled as hemispheres. The anterior sacral plateau edge is represented by an hemi-ellipsis. The modeled articular surfaces are projected on each X-ray. Their optimal location is obtained when the projected contours of their models best fit real outlines identified from landmark images. Linear and angular parameters characterizing the position of global pelvis and articular surfaces are calculated from the corresponding sets of axis. Relative positions of sacral plateau, and acetabular cavities, are then calculated. Two hundred standing pelvis, of subjects and scoliotic patients, have been studied. Examples are presented. They focus upon pelvis orientations, relative positions of articular surfaces, and pelvis asymmetries.

Objective: To investigate the clinical application of preoperative embolization of tumor feeding artery combined with intraoperative balloon occlusion of the abdominal aorta in performing the surgical resection of sacral tumors. Methods: Conventional surgical excision of sacral tumors was employed in 24 patients with sacral tumors (control group), while preoperative embolization of tumor feeding artery combined with intraoperative balloon occlusion of the abdominal aorta was carried out in 32 patients with sacral tumors (study group). The operation time, blood loss during the surgery and the one-year recurrence rate of both groups were documented, and the results were statistically analyzed. Results: Angiography showed that in the study group the sacral tumors were supplied by several vessels, and these feeding arteries were occluded separately. The tumors were successfully removed in all patients with the help of intraoperative balloon occlusion of the abdominal aorta. During the surgery, the surgical area was clearly exposed and the blood loss wa remarkably reduced. After the surgery, no ectopic vascular embolization, renal ischemia, limb ischemia or other complications occurred. Statistically significant difference in the operation time, blood loss during the surgery and the one-year recurrence rate existed between the two groups (P<0.05). Conclusion: Preoperative embolization of tumor feeding artery combined with intraoperative balloon occlusion of the abdominal aorta can effectively shorten the operation time, reduce the blood loss during the surgery and provide a clear surgical field, and thus the surgical safety can be significantly ensured.

The external morphology of the sacrum is demonstrably informative regarding tail type (i.e., tail presence/absence, length, and prehensility) in living and extinct primates. However, little research has focused on the relationship between tail type and internal sacral morphology, a potentially important source of functional information when fossil sacra are incomplete. Here, we determine if cortical bone cross-sectional thickness of the last sacral vertebral body differs among tail types in extant primates and can be used to reconstruct tail types in extinct primates. Cortical bone cross-sectional thickness in the last sacral vertebral body was measured from high-resolution CT scans belonging to 20 extant primate species (N = 72) assigned to tail type categories ("tailless," "nonprehensile short-tailed," "nonprehensile long-tailed," and "prehensile-tailed"). The extant dataset was then used to reconstruct the tail types for four extinct primate species. Tailless primates had significantly thinner cortical bone than tail-bearing primates. Nonprehensile short-tailed primates had significantly thinner cortical bone than nonprehensile long-tailed primates. Cortical bone cross-sectional thickness did not distinguish between prehensile-tailed and nonprehensile long-tailed taxa. Results are strongly influenced by phylogeny. Corroborating previous studies, Epipliopithecus vindobonensis was reconstructed as tailless, Archaeolemur edwardsi as long-tailed, Megaladapis grandidieri as nonprehensile short-tailed, and Palaeopropithecus kelyus as nonprehensile short-tailed or tailless. Results indicate that, in the context of phylogenetic clade, measures of cortical bone cross-sectional thickness can be used to allocate extinct primate species to tail type categories. © 2017 Wiley Periodicals, Inc.

Full Text Available Background: Surgical treatments for adult spinal deformities often include pelvic fixation, and the feasibility of sacral-2 alar iliac (S2AI screw fixation has been shown previously. However, sometimes S2AI screw fixation cannot be applied due to the presence of an osteolytic lesion or trauma or because the biomechanical properties of only an S2AI screw is insufficient. Therefore, we questioned the feasibility of using sacral AI screws in other segments and determined whether S3AI and S4AI screws have the potential to be used for sacral fractures. The aim of this study was to investigate the feasibility and radiological features of sacral AI fixation in S1–S4 in an adult population using 3D imaging techniques. Methods: Computed tomography (CT scans were taken of 45 patients and were imported into Mimics (Version 10.01, Materialise, Belgium software to reconstruct the 3D digital images. Next, a cylinder (radius of 3.5 mm was drawn to imitate the screw trajectory of a S1–4 AI screw, and every imitated screw in each segment was adjusted to a maximum upward and downward angle to acquire the feasible region. The parameters of the S1–4AI screw trajectories were measured. Results: Sacral AI screws could be successfully imitated using 3D digital imaging. The S4AI screw trajectory could be obtained in 19 of 45 patient images (42.2%, while the feasibility rates of S1AI, S2AI, and S3AI screw fixation were 100%, 100%, and 91.1% (41/45, respectively. The feasible regions of S1AI, S2AI, and S3AI screw trajectories were wide enough, while the adjustable angle of S4AI screws was very small. Conclusion: It is feasible to place S1–2AI screws in the entire adult population and S3–4AI screws in some of the adult population. Furthermore, our study suggested that 3D digital images are suitable to study the feasibility of new screw fixation.

S3 Dorsal Root Ganglion/Nerve Root Stimulation for Refractory Postsurgical Perineal Pain: Technical Aspects of Anchorless Sacral Transforaminal Lead Placement

Full Text Available Chronic perineal pain limits patients in physical and sexual activities, leading to social and psychological distress. In most cases, this pain develops after surgery in the urogenital area or as a consequence of trauma. Neuromodulation is one of the options in chronic postsurgical perineal pain treatment. We present a case of refractory perineal pain after right sided surgical resection of a Bartholin’s cyst which was treated with third sacral nerve root/dorsal root ganglion stimulation using the transforaminal approach. We describe a new anchorless lead placement technique using a unique curved lead delivery sheath. We postulate that this new posterior foraminal technique of lead placement is simple, safe, and reversible and may lower the occurrence of lead related complications.

To prove the feasibility of using Hounsfield attenuation values at MDCT to detect bone bruises related to sacral insufficiency fractures. Twenty-two patients with acute sacrum trauma and no fracture findings at MDCT were included in our prospective study. Two observers independently reviewed CTs regarding visual signs of bone bruises in 132 defined regions of the sacral alae. Interobserver agreement was tested by {kappa} statistics. Subsequently, HU values were obtained in the same regions, and attenuation differences between the two sides were calculated. Validity and reliability were assessed by intraclass correlation coefficient and Bland-Altman analysis. HU differences were subjected to ROC curve analysis to determine sensitivity, specificity, PPV and NPV. MRI served as standard reference. MRI revealed 19 regions with bone bruises and associated sacral insufficiency fractures. HU measurements demonstrated good validity and reliability (r = 0.989). ROC curve analysis exhibited an ideal cutoff value of 35.7 HU density difference between affected and non-affected regions. Visual evaluation revealed moderate agreement ({kappa} = 0.48); diagnostic accuracy was inferior to objective evaluation. Assessment of differences in bone marrow density by HU measurements is an objective and reliable tool for detection of bone bruises associated with occult sacral insufficiency fractures. (orig.)

Spinal cord injury (SCI) is a highly devastating injury with a variety of complications; among them are neurogenic bladder, bowel, and sexual dysfunction. We aimed to evaluate the effect of sacral anterior root stimulation with sacral deafferentation (SARS-SDAF) on neurogenic bladder and sexual dysfunction in a large well-defined spinal cord injury cohort. In the manner of cross-sectional study, subjects undergone SARS-SDAF between September 1986 and July 2011 answered a questionnaire concerning conditions before and after surgery in the department of Neuro-Urology, Bad Wildungen, Germany. In total 287 of 587 subjects were analyzed. Median age was 49 years (range 19-80), median time from SCI to surgery was 10 years (range 0-49), and from surgery to follow-up 13 years (range 1-25). Of the analyzed subjects, 100% of both gender used SARS for bladder emptying. On the visual analogue scale (VAS) ranging from 0 to 10 (best), satisfaction with SARS-SDAF was 10 concerning bladder emptying, however 5 and 8 regarding sexual performance, for female and male users, respectively. Baseline and follow-up comparison showed a decline in self-intermittent catheterization (p < 0.0001), partial catheterization by attendant (p = 0.0125), complete catheterization and suprapubic catheterization (p < 0.0001), transurethral catheterization (p < 0.0011), and fewer cases of involuntary urine leakage (p < 0.0001). The SARS-SDAF is a beneficial multi-potential treatment method with simultaneous positive effect on multi-organ dysfunction among SCI subjects.

Formation of the sacrum requires down-regulation of sonic hedgehog signaling in the sacral intervertebral discs.

In humans, the sacrum forms an important component of the pelvic arch, and it transfers the weight of the body to the lower limbs. The sacrum is formed by collapse of the intervertebral discs (IVDs) between the five sacral vertebrae during childhood, and their fusion to form a single bone. We show that collapse of the sacral discs in the mouse is associated with the down-regulation of sonic hedgehog (SHH) signaling in the nucleus pulposus (NP) of the disc, and many aspects of this phenotype can be reversed by experimental postnatal activation of HH signaling. We have previously shown that SHH signaling is essential for the normal postnatal growth and differentiation of intervertebral discs elsewhere in the spine, and that loss of SHH signaling leads to pathological disc degeneration, a very common disorder of aging. Thus, loss of SHH is pathological in one region of the spine but part of normal development in another. © 2018. Published by The Company of Biologists Ltd.

The aim of this study was to determine the long-term clinical efficacy and complications of neuromodulation with a unilateral sacral foramen electrode in 36 patients with chronic voiding dysfunction. Following a positive effect of a percutaneous nerve evaluation test, patients underwent open surgery. A permanent electrode was implanted in 24 patients with urge incontinence, in 6 with urgency-frequency syndrome, and in 6 with nonobstructive urinary retention. After an average follow-up period of 37.8 months, 19 patients (52.8%) continue to benefit from the neuromodulation with a significant improvement of symptoms and urodynamic parameters. The median duration of the therapeutic effect for the total study population was longer than 60 months. No significant difference in the median duration of therapeutic effect with regard to sex, the type of voiding disorder, or the implant pulse generator was found. However, in patients with previous psychological disorders the median duration of therapeutic effect was only 12 months (P = 0.008). Complications were mild. In the group of patients in whom the therapeutic effect remains, 37 reoperations have had to be performed. We conclude that although reoperations were needed to overcome technical problems, patients can achieve lasting symptomatic improvement. Since technical changes in the equipment have reduced the number of complications, even better results can be expected in terms of the reoperation rate.

Objective:To investigate the effect of injecting a compound of Bupivacaine and Fentanyl into sacral spinal space to treat chronic pelvic pain syndrome (CPPS). Methods: A total of 36 men with recalcitrant CPPS refractory to multiple prior therapies were treated with the injection of a compound of Bupivacaine and Fentanyl (10 ml of 0. 125% upivacaine, .05 mg Fentanyl, 5 mg Dexamethasone, 100 mg Vitamin B1 and 1 mg Vitamin B12) into sacral space once a week for 4 weeks. The National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI), maximum and average flow rate were performed at the start and the end of 4 weeks' therapy. Results :Mean NIH-CPSI total score was decreased from 26.5±.6 to 13.4±2.0 (P＜0. 001). Significant improvement was seen in each subscore domain. A total of 32 patients (89%) had at least 25% improvement on NIH-CPSI and 22 (61%) had at least 50% improvement. Maximal and average flow rate were increased from 19. 5±3.8 to 23. 6±4. 2 and 10. 9±2.6 to 14.3± 2.4 respectively. Conclusion: Injection of this compound of Bupivacaine, Fentanyl and Dexamethasone into sacral spinal space is an effective and safe approach for recalcitrant CPPS. Further study of the mechanisms and prospective placebo controlled trials are warranted.

Petrous apex meningocele (PAM) is an uncommon cystic lesion involving the petrous apex. The underlying cause of PAM may be related to chronic elevated intracranial pressure. The aim of the study was to explore the relationship between PAM and meningioma and between PAM and other intracranial hypertension findings. Two hundred seventy-eight consecutive patients with meningiomas were retrospectively studied. Fifty age- and gender-matched controls were also enrolled in this study. The incidence of PAM, empty sella, tortuosity of the optic nerve, and hydrops of optic nerve sheath was evaluated. The maximum width, area, volume of each PAM, or Meckel's cave and volume of meningioma were measured in controls and patients, separately. One hundred fifty-nine (57.19%) patients were detected with coexistent PAMs. One hundred twenty-five patients had bilateral PAMs, 34 had unilateral lesions, and the remaining 119 did not have PAM. Two subjects (4/50) had unilateral PAMs in normal controls. The maximum width, area, volume of PAM, or Meckel's cave were significantly larger in the patients with bilateral PAM group than those in the unilateral PAM group, in the group without PAM, and those in control group (p = 0.000). The volume of meningioma was positively correlated with the PAM volume (r = 0.48). There was a positive correlation for the incidence between PAM and (1) empty sella (r = 0.901) and (2) tortuosity of the optic nerves and hydrops of the optic sheath (r = 0.825). Coexistence of PAMs with meningiomas is not rare in incidence, and it suggests a potential role for chronically elevated intracranial pressure and disturbance of CSF circulation in their pathophysiology.

1989-01-01

Ten cases of brachial plexus injury were subjected to magnetic resonance (MR) to demonstrate the roots, trunks, divisions or cord abnormalities. Both normal and abnormal brachial plexuses were imaged in sagittal, axial, coronal and axial oblique planes. Myelography, using water soluble contrast agents, was performed in seven cases. MR demonstrated one traumatic meningocele, one extradural cerebrospinal fluid (CSF) collection, trunk and/or root neuromas in four, focal root fibrosis in two and diffuse fibrosis in the remaining two cases. Results of MR were confirmed at surgery in four cases with neuromas, while myelography was normal in two and was not carried out in the remaining two. In two cases, where MR demonstrated diffuse fibrosis of the brachial plexus, myelography showed C7 and T1 traumatic meningocele in one and was normal in the other. Both these patients showed excellent clinical and electrophysiological correlation with MR findings and in one of them surgical confirmation was also obtained. In the other two cases with focal nerve root fibrosis, myelography was normal in one and showed a traumatic meningocele in another. Operative findings in these cases confirmed focal root fibrosis but no root avulsion was observed although seen on one myelogram. Focal fibrosis, however, was noted at operation in more roots than was observed with MR. Initial experience suggests that MR may be the diagnostic procedure of choice for complete evaluation of brachial plexus injuries. (orig.)

Defective collagen biosynthesis in Marfan syndrome predisposes to dural defects such as dural ectasia, meningocele, and pseudomeningocele; thus, an increased index of suspicion for these conditions should be present in the clinical setting of Marfan syndrome. The authors describe a young woman with Marfan syndrome who was being treated with anticoagulants for a prosthetic heart valve and who presented with a spontaneous retroperitoneal hemorrhage requiring surgical evacuation. No CSF leak was encountered at surgery, but she developed progressively more severe positional headaches over the following year. She then experienced the sudden onset of acute urinary obstruction, at which time CT revealed a 17 × 15 × 13-cm presacral pseudomeningocele communicating with the thecal sac through a sacral bone defect. An anterior surgical approach was used for drainage of the pseudomeningocele as well as for primary closure of the dural defect with a bovine pericardial patch and autologous subcutaneous fat graft. After a short period of lumbar subarachnoid drainage of the CSF, the patient was able to resume normal activity without recurrent symptoms. To the authors' knowledge, such a pseudomeningocele in a patient with Marfan syndrome has been reported only twice, and this case features the largest pseudomeningocele to date. They also review the pertinent literature regarding presentation, diagnosis, and management of these lesions.

Background Many devices are in use to prevent pressure ulcers, but from most little is known about their effects and costs. One such preventive device is the Australian Medical Sheepskin that has been proven effective in three randomized trials. In this study the costs and savings from the use of the Australian Medical Sheepskin were investigated from the perspective of a nursing home. Methods An economic model was developed in which monetary costs and monetary savings in respect of the sheepskin were balanced against each other. The model was applied to a fictional (Dutch) nursing home with 100 beds for rehabilitation patients and a time horizon of one year. Input variables for the model consisted of investment costs for using the sheepskin (purchase and laundry), and savings through the prevented cases of pressure ulcers. The input values for the investment costs and for the effectiveness were empirically based on a trial with newly admitted rehabilitation patients from eight nursing homes. The input values for the costs of pressure ulcer treatment were estimated by means of four different approaches. Results Investment costs for using the Australian Medical Sheepskin were larger than the monetary savings obtained by preventing pressure ulcers. Use of the Australian Medical Sheepskin involves an additional cost of approximately €2 per patient per day. Preventing one case of a sacral pressure ulcer by means of the Australian Medical Sheepskin involves an investment of €2,974 when the sheepskin is given to all patients. When the sheepskin is selectively used for more critical patients only, the investment to prevent one case of sacral pressure ulcers decreases to €2,479 (pressure ulcer risk patients) or €1,847 (ADL-severely impaired patients). The factors with the strongest influence on the balance are the frequency of changing the sheepskin and the costs of washing related to this.

To determine the MR features of non-sacral, non-clival chordoma and to describe a MR prototype of the lesion.Design and patients We reviewed the MR findings of 10 patients with a histologically proven chordoma (6 cervical spine, 1 thoracic spine, 3 lumbar spine). There were three female and seven male patients. Age ranged from 12 to 66 years with a mean age of 44.6 years. The MR images were reviewed for signal intensity (SI) and morphology. All lesions showed a soft tissue extension spanning several vertebral segments. Most of the lesions exhibited a so-called collar button appearance (sagittal images). Two cases of cervical chordoma displayed a ''dumbbell morphology'' (axial images) or ''mushroom'' appearance without bone involvement and with enlargement of the neuroforamen mimicking a neurogenic tumor. Although the region of the nucleus pulposus is the last part of the fetal notochord in the adult to involute, disks were surprisingly spared in all patients. Eight of 10 patients showed heterogeneous SI on all sequences. The overall SI of all lesions was isointense or slightly higher than that of muscle on T1-weighted images. All lesions exhibited high SI on T2-weighted images. After gadolinium contrast administration there was a moderate enhancement in most cases. Although the SI on MR imaging is not specific, chordoma should be considered when a destructive lesion of a vertebral body is associated with a soft tissue mass with a collar button or mushroom appearance and dumbbell morphology, spanning several vertebral segments and sparing the disk(s).

The purpose of our study was to evaluate minimally invasive sacroiliac screw fixation for treatment of posterior pelvic instability with the help of CT controlled guidewires, assess its accuracy, safety and effectiveness, and discuss potential pitfalls. 100 guidewires and hollow titan screws were inserted in 38 patients (49.6±19.5 years) suffering from 35 sacral fractures and/or 16 sacroiliac joint disruptions due to 33 (poly-)traumatic, 2 osteoporotic and 1 post-infectious conditions. The guidewire and screw positions were analyzed in multiplanar reconstructions. The mean minimal distance between guidewire and adjacent neural foramina was 4.5±2.01mm, with a distinctly higher precision in S1 than S2. Eight guidewires showed cortical contacts, resulting in a total of 2% mismatched screws with subsequent wall violation. The fracture gaps were reduced from 3.6±0.53mm to 1.2±0.54mm. During follow-up 3 cases of minor iatrogenic sacral impaction (<5mm) due to the bolting and 2 cases of screw loosening were observed. Interventional time was 84.0min with a mean of 2.63 screws per patient whilst acquiring a mean of 93.7 interventional CT-images (DLP 336.7mGycm). The treatment of posterior pelvic instability with a guidewire-based screw insertion technique under CT-imaging results in a very high accuracy and efficacy with a low complication rate. Careful attention should be drawn to radiation levels. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Our goal was to assess the technical results in patients who underwent long-axis sacroplasty for the treatment of sacral insufficiency fractures (SIF) by radiofrequency-induced high-viscosity bone cement augmentation. Twelve patients with bilateral sacral fractures were treated by augmentation with radiofrequency-activated, high-viscosity polymethylmethacrylate (PMMA) bone cement under local anesthesia. CT-guided sacroplasty was performed by using a long-axis approach through a single entry point. Thirty-six vertebrae were treated in 12 sessions under a combination of CT and fluoroscopic guidance using a bilateral access and a cavity-creating osteotome prior to remote-controlled, hydraulically driven cement injection. The visual analogue scale (VAS) score before sacroplasty and at 1 and 3 months after the treatment was obtained. PMMA leaks were evaluated retrospectively using the post-interventional CT. The mean amount of high-viscosity PMMA injected per patient was 7.8 ml. No major adverse events were observed. In the first 4 days after the procedure, the mean VAS score decreased from 8.1 ± 1.9 to mean 3.1 ± 1.2 and was followed by a gradual but continuous decrease throughout the rest of the follow-up period at 24 weeks (mean 2.2 ± 1.1) and 48 weeks (mean 2.1 ± 1.4). CT fluoroscopy-guided sacral augmentation was safe and effective in all 12 patients with osteoporotic SIF. (orig.)

This randomized trial compared ultrasound (US)- and fluoroscopy-guided sacral lateral branch (SLB) blocks. We hypothesized that US would require a shorter performance time. Forty patients who required unilateral sacral lateral branch blocks for chronic low back pain were randomized to US or fluoroscopy guidance. Before the performance of the assigned block, an investigator who was not involved in patient care carried out baseline analgesic testing. With US, the dorsal sacroiliac ligament, the sacroiliac joint, and the interosseous ligament were probed with a 22-gauge block needle. The patient was asked to rate the level of discomfort using an 11-point numerical rating scale.After the analgesic test, attending anesthesiologists or supervised trainees carried out the SLB blocks. The local anesthetic agent (lidocaine 2%) was identical in all subjects. In the US group, local anesthetic (1.5 mL) was first injected on the lateral crest at the mid-point between S2 and S3. Subsequently, 2 more injections of 0.5 mL were carried out on the lateral crest, immediately cephalad to S2 and at the S1 level. In the fluoroscopy group, SLB blocks were performed according to a previously described 17-injection technique, which involves 9 skin entry sites and the targeting of the L5 posterior root and S1-S3 sacral lateral branches. A 0.4-mL volume of local anesthetic was deposited at each target point. The performance time, number of needle passes, and the incidence of vascular breach were recorded during the performance of the block.Twenty minutes after the end of local anesthetic injection, the same investigator who performed preblock analgesic testing carried out postblock testing in an identical manner. Compared with fluoroscopy, the US technique was associated with a shorter performance time (267.5 ± 99.3 vs 628.7 ± 120.3 seconds; P < 0.001), fewer needle passes and a lower incidence of vascular breach (0 vs 10 occurrences; P = 0.001). However, the block effect (ie, the

In this study we aimed to develop a simple and practical technique for chronic sacral epidural catheterization of rabbits. We included ten rabbits weighing 2-2.5 kg in the study. After anesthesia and analgesia, we placed an epidural catheter by a 2 cm longitudinal skin incision in the tail above the sacral hiatus region. We confirmed localization by giving 1% lidocaine (leveling sensory loss and motor function loss of the lower extremity). The catheter was carried forward through a subcutaneous tunnel and fixed at the neck. Chronic caudal epidural catheter placement was succesful in all rabbits. The catheters stayed in place effectively for ten days. We encountered no catheter complications during this period. The localization of the catheter was reconfirmed by 1% lidocaine on the last day. After animals killing, we performed a laminectomy and verified localization of the catheter in the epidural space. Various methods for catheterization of the epidural space in animal models exist in the literature. Epidural catheterization of rabbits can be accomplished by atlanto-occipital, lumbar or caudal routes by amputation of the tail. Intrathecal and epidural catheterization techniques defined in the literature necessitate surgical skill and knowledge of surgical procedures like laminectomy and tail amputation. Our technique does not require substantial surgical skill, anatomical integrity is preserved and malposition of the catheter is not encountered. In conclusion, we suggest that our simple and easily applicable new epidural catheterization technique can be used as a model in experimental animal studies.

[Purpose] This study aimed to determine whether low-frequency current therapy can be used to reduce the symptoms of idiopathic slow transit constipation (ISTC). [Subjects] Fifteen patients (ten male and five female) with idiopathic slow transit constipation were enrolled in the present study. [Results] Bowel movements per day, bowel movements per week, and constipation assessment scale scores significantly improved after low-frequency current simulation of S2-S3. [Conclusion] Our results show that stimulation with low-frequency current of the sacral dermatomes may offer therapeutic benefits for a subject of patients with ISTC.

Low back pain post partum - A case report.

LENUS (Irish Health Repository)

2012-02-23

Sacral stress fracture is an unusual source of low back pain and can be easily confused with a number of other clinical conditions seen in physiotherapy clinics. The purpose of this case report is to describe the case of a patient presenting with low back pain post partum illustrating pertinent aspects of differential diagnosis and issues of management. A 31 year old female presented complaining of low back pain since the birth of her second child 11 months earlier. Subjective and objective examination led the Therapist to consider a diagnosis of sacral stress fracture. This diagnosis was confirmed by MRI. Three months after presenting to physiotherapy the patient was pain free and had returned to all aspects of her daily life without any difficulties. Clinicians must be aware of the less common pathologies in any hypotheses development. A careful history and physical examination and broad hypotheses generation will ensure that patients are accurately diagnosed and receive appropriate and effective treatments.

The aim of this study is to examine the relationship between lumbar lordosis and pars interarticularis fractures. In this retrospective case-control study we compare the angle of lumbar lordosis and the angle of the S1 vertebral endplate (as a measure of pelvic tilt) in patients with bilateral L5 pars interarticularis fractures with age- and sex-matched control cases with normal MRI examinations of the lumbar spine. Twenty-nine cases of bilateral L5 pars interarticularis fractures with matched control-cases were identified on MRI (16 male, 13 female, age 9-63 years). The angle of lordosis was measured between the inferior L4 and superior S1 vertebral endplates on a standing lateral lumbar spine radiograph for both groups. The mean angle of lordosis about the L5 vertebra was 36.9 (SD = 6.5 ) in the pars interarticularis fracture group, and 30.1 (SD = 6.4 ) in the control group. The difference between the two groups was significant (mean difference 6.8 , Student's t test: P < 0.001). The mean angle of sacral tilt measured was 122.2 (SD = 10.16 ) for controls and 136.4 (SD = 10.86 ) for patients with pars defects. The difference in the means of 14.2 was statistically significantly different (P < 0.0001). Sacral tilt represented by a steeply angled superior endplate of S1 is associated with a significantly increased angle of lordosis, between L4 and S1, and pars fractures at L5. Steep angulation of the first sacral vertebral segment maybe the predisposing biomechanical factor that leads to pincer-like impingement of the pars interarticularis and then spondylolysis. (orig.)

To examine how the median sacral artery (MSA) is involved with the coccygeal body or glomus coccygeum, we studied serial frontal or sagittal sections of 14 embryos (approximately 5-6 weeks of gestation) and 12 fetuses (10-18 weeks). At five weeks, the caudal end of the dorsal aorta (i.e., MSA) accompanied putative sympathetic ganglion cells in front of the upper coccygeal and lower sacral vertebrae. At six weeks, a candidate for the initial coccygeal body was identified as a longitudinal arterial plexus involving nerve fibers and sympathetic ganglion cells between arteries. At 10-18 weeks, the MSA exhibited a highly tortuous course at the lower sacral and coccygeal levels, and was attached to and surrounded by veins, nerve fibers, and sympathetic ganglion cells near and between the bilateral origins of the levator ani muscle. Immunohistochemistry demonstrated expression of tyrosine hydroxylase and chromogranin A in the nerves. However, throughout the stages examined, we found no evidence suggestive of an arteriovenous anastomosis, such as well-developed smooth muscle. An acute anterior flexure of the vertebrae at the lower sacrum, as well as regression of the secondary neural tube, seemed to induce arterial plexus formation from an initial straight MSA. Nerves and ganglion cells were likely to be secondarily involved with the plexus because of the close topographical relationship. However, these nerves might play a major role in the extreme change into adult morphology. An arteriovenous anastomosis along the MSA might be an overinterpretation, at least in the prenatal human.

An audit of the physiotherapy management of paraplegic patients with sacral pressure sores

Directory of Open Access Journals (Sweden)

D. Pather

2013-01-01

Full Text Available Introduction: Pressure sores are the most common complication post spinal cord injury that requires patients to be on bed rest. Patient bed rest delay rehabilitation and may lead to other complications associated with immobility. This study sought to establish the treatment interventions physiotherapists provide to patients with sacral pressure sores and the factors that they consider when deciding whether the patient should receive physiotherapy in the ward or gym. Methods: This was a questionnaire based survey of physiotherapists working in spinal cord injury rehabilitation units in South Africa. The self-designed questionnaire was sent to all the main spinal rehabilitation units in the country (14 located in Gauteng, Kwa-Zulu Natal, Western Cape, Eastern Cape and Free State provinces. Results: Thirty-nine physiotherapists from a total of 51 completed the questionnaires (76% response rate. The most common treatment practice for patients with sacral pressure sores was bed rest (98%. The most common physio-therapy practices (70% included were upper limb muscle strengthening, upper and lower limb passive movements, positioning into prone and side lying and passive stretching. The choice of treatment environment was influenced by doctors’ orders and the size, grade and duration of the pressure sores. Conclusion: Direct involvement in pressure sore management in South Africa seem to be less than in other parts of the world. If we are to minimise the pressure sore impact, it appears like we need more focus on gait re-education and standardised ADL programmes and patient treatment in the gym to possibly maximise healing and rehabilitation.

Hyun Ho Han

2016-01-01

Full Text Available The sacral area is the most common site of pressure sore in bed-ridden patients. Though many treatment methods have been proposed, a musculocutaneous flap using the gluteus muscles or a fasciocutaneous flap is the most popular surgical option. Here, we propose a new method that combines the benefits of these 2 methods: combined V-Y fasciocutaneous advancement and gluteus maximus muscle rotational flaps. A retrospective review was performed for 13 patients who underwent this new procedure from March 2011 to December 2013. Patients’ age, sex, accompanying diseases, follow-up duration, surgical details, complications, and recurrence were documented. Computed tomography was performed postoperatively at 2 to 4 weeks and again at 4 to 6 months to identify the thickness and volume of the rotational muscle portion. After surgery, all patients healed within 1 month; 3 patients experienced minor complications. The average follow-up period was 13.6 months, during which time 1 patient had a recurrence (recurrence rate, 7.7%. Average thickness of the rotated muscle was 9.43 mm at 2 to 4 weeks postoperatively and 9.22 mm at 4 to 6 months postoperatively (p=0.087. Muscle thickness had not decreased, and muscle volume was relatively maintained. This modified method is relatively simple and easy for reconstructing sacral sores, provides sufficient padding, and has little muscle donor-site morbidity.

Purpose: To evaluate the efficacy, post-treatment function, toxicity, and complications of carbon ion radiotherapy (RT) for sacral chordoma compared with surgery. Methods and Materials: The records of 17 primary sacral chordoma patients treated since 1990 with surgery (n = 10) or carbon ion RT (n = 7) were retrospectively analyzed for disease-specific survival, local recurrence-free survival, complications, and functional outcome. The applied carbon ion dose ranged from 54.0 Gray equivalent (GyE) to 73.6 GyE (median 70.4). Results: The mean age at treatment was 55 years for the surgery group and 65 years for the carbon ion RT group. The median duration of follow-up was 76 months for the surgery group and 49 months for the carbon ion RT group. The local recurrence-free survival rate at 5 years was 62.5% for the surgery and 100% for the carbon ion RT group, and the disease-specific survival rate at 5 years was 85.7% and 53.3%, respectively. Urinary-anorectal function worsened in 6 patients (60%) in the surgery group, but it was unchanged in all the patients who had undergone carbon ion RT. Postoperative wound complications requiring reoperation occurred in 3 patients (30%) after surgery and in 1 patient (14%) after carbon ion RT. The functional outcome evaluated using the Musculoskeletal Tumor Society scoring system revealed 55% in the surgery group and 75% in the carbon ion RT group. Of the six factors in this scoring system, the carbon ion RT group had significantly greater scores in emotional acceptance than did the surgery group. Conclusion: Carbon ion RT results in a high local control rate and preservation of urinary-anorectal function compared with surgery.

Purpose: To assess the efficacy of definitive treatment of sacral chordoma by high-dose proton/photon-beam radiation therapy alone or combined with surgery. Methods and Materials: The records of 16 primary and 11 recurrent sacral chordoma patients treated from November 1982 to November 2002 by proton/photon radiation therapy alone (6 patients) or combined with surgery (21 patients) have been analyzed for local control, survival, and treatment-related morbidity. The outcome analysis is based on follow-up information as of 2005. Results: Outcome results show a large difference in local failure rate between patients treated for primary and recurrent chordomas. Local control results by surgery and radiation were 12/14 vs. 1/7 for primary and recurrent lesions. For margin-positive patients, local control results were 10 of 11 and 0 of 5 in the primary and recurrent groups, respectively; the mean follow-up on these locally controlled patients was 8.8 years (4 at 10.3, 12.8, 17, and 21 years). Radiation alone was used in 6 patients, 4 of whom received ≥73.0 Gy (E); local control was observed in 3 of these 4 patients for 2.9, 4.9, and 7.6 years. Conclusion: These data indicate a high local control rate for surgical and radiation treatment of primary (12 of 14) as distinct from recurrent (1 of 7) sacral chordomas. Three of 4 chordomas treated by ≥73.0 Gy (E) of radiation alone had local control; 1 is at 91 months. This indicates that high-dose proton/photon therapy offers an effective treatment option

To compare the stability of lengthened sacroiliac screw and standard sacroiliac screw for the treatment of unilateral vertical sacral fractures; to provide reference for clinical applications. A finite element model of Tile type C pelvic ring injury (unilateral Denis type II fracture of the sacrum) was produced. The unilateral sacral fractures were fixed with lengthened sacroiliac screw and sacroiliac screw in six different types of models respectively. The translation and angle displacement of the superior surface of the sacrum (in standing position on both feet) were measured and compared. The stability of one lengthened sacroiliac screw fixation in S1 or S2 segment is superior to that of one sacroiliac screw fixation in the same sacral segment. The stability of one lengthened sacroiliac screw fixation in S1 and S2 segments respectively is superior to that of one sacroiliac screw fixation in S1 and S2 segments respectively. The stability of one lengthened sacroiliac screw fixation in S1 and S2 segments respectively is superior to that of one lengthened sacroiliac screw fixation in S1 or S2 segment. The stability of one sacroiliac screw fixation in S1 and S2 segments respectively is markedly superior to that of one sacroiliac screw fixation in S1 or S2 segment. The vertical and rotational stability of lengthened sacroiliac screw fixation and sacroiliac screw fixation in S2 is superior to that of S1. In a finite element model of type C pelvic ring disruption, S1 and S2 lengthened sacroiliac screws should be utilized for the fixation as regularly as possible and the most stable fixation is the combination of the lengthened sacroiliac screws of S1 and S2 segments. Even if lengthened sacroiliac screws cannot be systematically used due to specific conditions, one sacroiliac screw fixation in S1 and S2 segments respectively is recommended. No matter which kind of sacroiliac screw is used, if only one screw can be implanted, the fixation in S2 segment is more recommended

The study assessed the initial experience with posterior tibial nerve stimulation (PTNS) for faecal incontinence and compared it with sacral nerve stimulation (SNS) performed in a single centre during the same timespan. A retrospective review of a prospectively collected database was conducted at the colorectal unit, University Hospital, Nantes, France, from May 2009 to December 2010. Seventy-eight patients diagnosed with chronic severe faecal incontinence underwent neurostimulation including PTNS in 21 and SNS in 57. The main outcome measures were faecal incontinence (Wexner score) and quality of life (Fecal Incontinence Quality of Life, FIQL) scores in a short-term follow-up. No significant differences were observed in patients' characteristics. Of 57 patients having SNS, 18 (32%) failed peripheral nerve evaluation and 39 (68%) received a permanent implant. Two (5%) developed a wound infection. No adverse effects were recorded in the PTNS group. There was no significant difference in the mean Wexner and FIQL scores between patients having PTNS and SNS at 6 (P = 0.39 and 0.09) and 12 months (P = 0.79 and 0.37). A 50% or more improvement in Wexner score was seen at 6 and 12 months in 47% and 30% of PTNS patients and in 50% and 58% of SNS patients with no significant difference between the groups. Posterior tibial nerve stimulation is a valid method of treating faecal incontinence in the short term when conservative treatment has failed. It is easier, simpler, cheaper and less invasive than SNS with a similar short-term outcome. Colorectal Disease © 2014 The Association of Coloproctology of Great Britain and Ireland.

Full Text Available Meningomyelocoele is a developmental congenital disorder caused by failure of the neural tube to close during the first month of embryonic development thus presenting with herniation of neural elements along with meninges. Myelomeningocoeles most commonly occur in the lumbosacral region, but can also occur at any level in the neuraxis, including occipital/suboccipital areas or nasally (encephalocoele.We report a rare case of double meningomyelocoele in a 4-month-old infant (cervical as well as thoracic meningocele with weakness in the left lower limb (power grade 0 posted for resection with difficult intubation because of obstructive hydrocephalus, fear of rupture of neuroplaque, positioning and care of blood loss and temperature. The infant was discharged within 15 days, and his hospital stay was uneventful.

The pattern of distribution of surgically treated symptomatic prolapsed lumbar and sacral intervertebral discs has been published, though scantily, especially in males. We decided to look at our own series, compare and contrast ours with some of those published. We treated 88 locations of this lesion in 68 males. The clinical features were those of lower back pains, with or without radiation into the lower extremities, sensory loss and paresis of the limbs. There was a case of loss of urinary bladder and ano-rectal control. All lesions were confirmed through cauda-equinograms and treated under general anaesthesia in knee-chest position (MECCA position). The patients were followed up for 3-6 months post-operatively. There were 88 locations in 68 males of 21-70 years of age, with 29 prolapses occurring during the age range 31-40 years, while 54 locations were on the left and 48 at L4/5. The procedures were well tolerated by all patients and there were no post-operative complications. This lesion in our series occurred mostly on the left, at the L4/5 level and peaked at 31-40 years age range. The predictability of occurrence of this disease, using side, level and age is still not feasible in males from our series.

Drainage or Packing of the Sella? Transsphenoidal Surgery for Primary Pituitary Abscess: Report of Two Cases

Directory of Open Access Journals (Sweden)

Soichi Oya

2009-01-01

Full Text Available The detailed surgical procedure of the transsphenoidal surgery for pituitary abscess has scarcely been described previously because it is a very rare clinical entity. The authors reported two cases of primary pituitary abscess. In case 1, the anterior wall of the sella turcica was reconstructed with the vomer bone after irrigating the abscess cavity, but the sella was not packed by fat for fear of the persistent infection by devascularized tissues. This led to the postoperative meningocele, the cerebrospinal fluid leak, and bacterial meningitis despite the successful abscess drainage. In case 2, tight sellar packing and reconstruction of the sellar wall were performed to avoid these postoperative complications, which resulted in complete drainage and uneventful postoperative course. Although accumulation of more cases is obviously needed to establish the definitive surgical technique in pituitary abscess surgery, our experience might suggest that packing of the sella is not impeditive for postoperative sufficient drainage.

To evaluate time efficiency, radiation dose, precision and complications of percutaneous iliosacral screw placement under CT-guidance in local anaesthesia. Retrospective analysis of 143 interventions in 135 patients during a period of 42 months. Implant failures could be evaluated in 85/182 screws and bony healing or refracturing in 46/182 screws. A total of 182 iliosacral screw placements in 179 vertical sacral fractures (105 unilateral, 37 bilateral) took place in 135 patients. 166/179 of the sacral fractures were detected in Denis zone 1, 10 in Denis zone 2 and 3 in Denis zone 3. No screw misplacements including the simultaneous bilateral procedures were noted. The average time for a unilateral screw placement was 23 minutes (range: 14-52 minutes) and 35 minutes (range: 21-60 minutes) for simultaneous bilateral screwing. The dose length product was 365 mGy x cm (range: 162-1014 mGy x cm) for the unilateral and 470 mGy x cm (range: 270-1271 mGy x cm) for the bilateral procedure. 1 gluteal bleeding occurred as the only acute minor complication (0.7%). Fracture healing was verified with follow-up CTs in 42/46 sacral fractures after screw placement. Backing out occurred in 12/85 screws between 6 and 69 days after intervention. In 8 patients contralateral stress fractures were detected after unilateral screw placement between day 10 and 127 (average: 48 days). CT-guided iliosacral screw placement in sacral fractures is a safe tool providing a very high precision. The radiation dose is in the order of a diagnostic CT of the pelvis for both unilateral and bilateral screws. Contralateral stress fractures in unilateral screw placements have to be considered during the first weeks after intervention.

This study aimed to generate data for the S1 and S2 alar pedicle and body and the alar orientations for both dysmorphic and normal sacra. The study comprised two groups: Group N consisted of 53 normal sacra and Group D included 10 dysmorphic sacra. Various features such as alar pedicle circumference; anterior, middle, and posterior axis of the sacral ala; sacral body height and width; and sagittal thickness were measured. In group N, the median anterior axis of the alae was observed to be 30° on the right and 25° on the left, the median midline axis was found to be 20° on the right and 15° on the left, and the median posterior alar axis was -15° on the right and -20° on the left. The true S1 and S2 alar pedicle circumferences were observed to be significantly smaller in group D, which demonstrated a shorter S1 alar pedicle mean circumference, significantly narrower S1 body mean width, and considerably tapered sagittal thickness. Our analysis indicated that dysmorphic sacra have a lower sagittal thickness and width of bodies and smaller alar pedicles, which explains the difficulties in their percutaneous fixation.

Highlights: • Minimally invasive sacroiliac screw fixation can be performed under CT-imaging. • Guidewires help in precise placement of cannulated sacroiliac screw. • Only a diminishing rate of misplacements can be seen. • The method appears to be a safe and very accurate procedure. - Abstract: Objective: The purpose of our study was to evaluate minimally invasive sacroiliac screw fixation for treatment of posterior pelvic instability with the help of CT controlled guidewires, assess its accuracy, safety and effectiveness, and discuss potential pitfalls. Methods: 100 guidewires and hollow titan screws were inserted in 38 patients (49.6 ± 19.5 years) suffering from 35 sacral fractures and/or 16 sacroiliac joint disruptions due to 33 (poly-)traumatic, 2 osteoporotic and 1 post-infectious conditions. The guidewire and screw positions were analyzed in multiplanar reconstructions. Results: The mean minimal distance between guidewire and adjacent neural foramina was 4.5 ± 2.01 mm, with a distinctly higher precision in S1 than S2. Eight guidewires showed cortical contacts, resulting in a total of 2% mismatched screws with subsequent wall violation. The fracture gaps were reduced from 3.6 ± 0.53 mm to 1.2 ± 0.54 mm. During follow-up 3 cases of minor iatrogenic sacral impaction (<5 mm) due to the bolting and 2 cases of screw loosening were observed. Interventional time was 84.0 min with a mean of 2.63 screws per patient whilst acquiring a mean of 93.7 interventional CT-images (DLP 336.7 mGy cm). Conclusions: The treatment of posterior pelvic instability with a guidewire-based screw insertion technique under CT-imaging results in a very high accuracy and efficacy with a low complication rate. Careful attention should be drawn to radiation levels

Full Text Available PURPOSE: To study the effects of percutaneous reconstruction plate internal fixation in the treatment of unstable sacral fractures. METHODS: Percutaneous reconstruction plate internal fixation was applied on 21 cases of unstable sacral fracture (15 males and six females, at age range of 16-65 years, mean 38.3 years including four cases of Denis Zone I, 14 cases of Zone II and three cases of Zone III. In operation, an arc incision (about 3-5 cm long was made along the iliac crest on the outside border of posterior superior iliac spine (PSIS on both sides, and then the plate was transported from the wounded side to the opposite one through the subcutaneous tunnel. RESULTS: The mean incision length, operation time, intraoperative blood loss was 4.3cm, 45.2min, and 160.8ml respectively. All these patients were followed up for 12-33 months (average 16.3 months, which showed no incision infection, intraoperative neurovascular injury, internal fixation loose or breakage, disunion, or obvious lower limb length inequality. The function result was rated as excellent in six cases, good in 12 and fair in 3, with excellence rate of 85.7%, according to the Majeed scoring system. CONCLUSION: Percutaneous reconstruction plate internal fixation is an ideal surgical approach to unstable sacral fractures, as it is easy, safe, causing less trauma and fewer complications, and conducive to quicker recovery.OBJETIVO: Estudar os efeitos da reconstrução percutânea com fixação de placa interna no tratamento de fraturas sacrais instáveis.

A clinical retrospective study was conducted. To evaluate the clinical and radiographic outcome of reduction followed by trans-sacral interbody fusion for high-grade spondylolisthesis. In situ posterior interbody fusion with fibula allograft has improved the fusion rates for patients with high-grade spondylolisthesis. The use of this technique in conjunction with partial reduction has not been reported. Nine consecutive patients underwent treatment of high-grade (Grade 3 or 4) spondylolisthesis with partial reduction followed by posterior interbody fusion using cortical allograft. The average age at the time of surgery was 27 years (range, 8-51 years), and the average follow-up period was 43 months (range, 24-72 months). Before surgery, eight patients had low back pain, seven patients had radiating leg pain, and five patients had hamstring tightness. The average grade of spondylolisthesis by Meyerding grading was 3.9 (range, 3-5). Charts and radiographs were evaluated, and outcomes were collected by use of the modified SRS outcomes instrument. Radiographic indexes demonstrated significant improvement with partial reduction and fusion. The slip angle, as measured from the inferior endplate of L5, improved from 41.2 degrees (range, 24-82 degrees ) before surgery to 21 degrees (range, 5-40 degrees ) after surgery. All the patients were extremely or somewhat satisfied with surgery. The two patients who underwent this operation without initial instrumentation experienced fractures of their interbody grafts. Both of these patients underwent repair of the pseudarthrosis with placement of trans-sacral pedicle screw instrumentation and subsequent fusion. Partial reduction followed by posterior interbody fusion is an effective technique for the management of high-grade spondylolisthesis in pediatric and adult patient populations, as assessed by radiographic and clinical criteria. Pedicle screw instrumentation with the sacral screws capturing L5 is recommended when this

Sacral Nerve Stimulation For Urinary Urge Incontinence, Urgency-Frequency, Urinary Retention, and Fecal Incontinence

Science.gov (United States)

2005-01-01

Executive Summary Objective The aim of this review was to assess the effectiveness, safety, and cost of sacral nerve stimulation (SNS) to treat urinary urge incontinence, urgency-frequency, urinary retention, and fecal incontinence. Background: Condition and Target Population Urinary urge incontinence, urgency-frequency, urinary retention, and fecal incontinence are prevalent, yet rarely discussed, conditions. They are rarely discussed because patients may be uncomfortable disclosing their symptoms to a health professional or may be unaware that there are treatment options for these conditions. Briefly, urge incontinence is an involuntary loss of urine upon a sudden urge. Urgency-frequency is an uncontrollable urge to void, which results in frequent, small-volume voids. People with urgency-frequency may or may not also experience chronic pelvic pain. Urinary retention refers to the inability to void despite having the urge to void. It can be caused by a hypocontractile detrusor (weak or no bladder muscle contraction) or obstruction due to urethral overactivity. Fecal incontinence is a loss of voluntary bowel control. The prevalence of urge incontinence, urgency-frequency, and urinary retention in the general population is 3.3% to 8.2%, and the prevalence of fecal incontinence is 1.4% to 1.9%. About three-quarters of these people will be successfully treated by behaviour and/or drug therapy. For those who do not respond to these therapies, the options for treatment are management with diapers or pads, or surgery. The surgical procedures are generally quite invasive, permanent, and are associated with complications. Pads and/or diapers are used throughout the course of treatment as different therapies are tried. Patients who respond successfully to treatment may still require pads or diapers, but to a lesser extent. The Technology Being Reviewed: Sacral Nerve Stimulation Sacral nerve stimulation is a procedure where a small device attached to an electrode is

Obesity can predispose women to pelvic organ prolapse and can also affect the success of pelvic organ prolapse surgery. The purpose of this study was to compare the postoperative anatomical outcomes following sacral colpopexy (SC) and transvaginal mesh colpopexy in a group of obese women with pelvic organ prolapse. We conducted a retrospective cohort study of obese women who underwent SC (n = 56) or transvaginal mesh colpopexy (n = 35). Follow-up ranged from 6 to 12 months. Preoperative, perioperative, and postoperative variables were compared using Student t, Mann-Whitney U, and Fisher exact tests, and by analysis of covariance. The women in the SC group had significantly higher mean apical vaginal measurements (P transvaginal mesh colpopexy group. There were no significant differences between the groups for other postoperative outcomes, including mesh erosion, recurrent prolapse symptoms, dyspareunia, and surgical satisfaction (P > 0.05). In these 91 obese patients with pelvic organ prolapse, SC resulted in better anatomical outcomes than transvaginal mesh colpopexy. However, the two procedures had similar outcomes with regard to recurrent symptoms and surgical satisfaction.

It is perfected with retrospective and prospective method precisely of its epidemiologic part summarizing notices from patients' histories which in 2000-2006 are hospitalized in Neurosurgery Clinic from (QFLPK)--Pediatric Clinic and Children Box (Department)--Gynecology Clinic and from Sanitary Regional Center throughout Kosova. Our study objects were two groups, as the first group 90 patients with spinal dysraphism where neurosurgery operations were done and classified types of dysraphism. At myelomeningocele hydrocephalus has dominated and in a percent of appearance and as acute of its active form was 97% of hydrocephalus form where subjected to cerebrospinal liquid derivation with ventriculo -peritoneal shunt in comparison with meningocele we do not have involvation of spinal nerve element, hydrocephalus takes active form with intervention indication in 60% of cases. Reflection in shown deficit aspect is totally different at myelomeningoceles where lower paraplegia dominate more than paraparesis. The second patient operative technique developed by hydrocephalus with neurosurgical intervention indication has to do with placing of (VP) ventriculo- peritoneal system (shant) at myelomeningoceles with hydrocephalus 58 cases and 12 cases meningoceles with hydrocephalus. Post operative meningitis (shant meningitis): from 70 operated cases of hydrocephalus with spinal dysraphism shunts complications from all types are just cases. Finally that appearance of hydrocephalus compared at spinal dysraphism dominate at myellomeningoceles as in notice time aspect, it is persisting and further acute, with vital motivation for neurosurgical

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 lordosis only showed minor differences. At all levels except for L5 / S1, lordosis measured by means of standing radiographs was higher than that measured by MRI. The difference in global lumbar L1-S1 lordosis was -2.9°. Analysis of the Roussouly groups showed the largest difference for L1-S1 (-8.3°) in group 2. In group 4, when measured on MRI, L5 / S1 lordosis (25.71°) was lower than L4 / L5 lordosis (27.63°) compared to the other groups. Conclusions  Although measurements of global lumbar lordosis significantly differed between the two scanning technologies, the mean difference was just 2.9°. MRI in supine position may be used for estimating global lumbar lordosis, but single level lordosis should be determined by means of standing radiographs. Key Points   · Large

1989-01-01

In spite of great progress in surgical treatment of anorectal malformations, fecal incontinence is still, in variable degrees, a frequent and unpleasant postsurgical sequela. The most frequent causes of incontinence are: 1) the incorrect placement of the pulled-through colon in the levator ani and sphincteric muscular complex during abdomino-perineal surgical procedures; 2) the poor development of sphinteric musculature; 3) the associated sacral anomalies. Postoperative CT helps to evaluate all the above-mentioned conditions, in view of possible new surgical procedure for improving continence (besides postoperative CT can help in choosing the more suitable surgical technique). Nine patients, aged 3 to 13 years (2 with good continence and 7 with various degrees of incontinence), were studied with pelvic postoperative CT. In the cases (2) with good continence the CT picture was: good development of sphincteric musculature and neo-anorectum correctly placed into sphinteric musculature; in the cases (3) with low degree of continence: neoanorectum correctly placed, but hypoplasic puborectal muscle; in the case (4) with complete incontinence, neo-anorectum incorrectly placed and poor development of sphinteric musculature. A further Posterior Sagittal Anorectoplasty (according Pena) is only suitable in the incontinence cases with: 1) neo-anorectum seriously misplaced; 2) good development of sphinteric musculature; 3) absence of sacral anomalies. Postoperative CT is a valid mean for demostrating all the above-mentioned conditions and for chooosing the best surgical technique in each case

The members of the lymphotoxin (LT) family of molecules play a critical role in lymphoid organogenesis. Whereas LT alpha-deficient mice lack all lymph nodes and Peyer's patches, mice deficient in LT beta retain mesenteric lymph nodes and cervical lymph nodes, suggesting that an LT beta-independent pathway exists for the generation of mucosal lymph nodes. In this study, we describe the presence of a lymph node in LT beta-deficient mice responsible for draining the genital mucosa. In the majority of LT beta-deficient mice, a lymph node was found near the iliac artery, slightly misplaced from the site of the sacral lymph node in wild-type mice. The sacral lymph node of the LT beta-deficient mice, as well as that of the wild-type mice, expressed the mucosal addressin cell adhesion molecule-1 similar to the mesenteric lymph node. Following intravaginal infection with HSV type 2, activated dendritic cells capable of stimulating a Th1 response were found in this sacral lymph node. Furthermore, normal HSV-2-specific IgG responses were generated in the LT beta-deficient mice following intravaginal HSV-2 infection even in the absence of the spleen. Therefore, an LT beta-independent pathway exists for the development of a lymph node associated with the genital mucosa, and such a lymph node serves to generate potent immune responses against viral challenge.

Analysis of 25 patients with normal computed tomographic appearances at the lumbosacral junction revealed wide variation in the anatomical level at which the first sacral nerve root sheaths were seen emerging from the theca. In nine patients (36%), the S1 nerve root sheaths were first recognized at the level of the lumbosacral disc. In 14 patients (56%), the sheaths emerged cranial to the disc; it is possible that these patients may be more prone to neurological complications related to disc or facet joint disease, especially if the sheath is laterally sited within the lateral recess. Conversely, that minority of patients (two, 8%) in whom the root sheaths emerge caudal to the disc level may be relatively protected from neurological complications.

To assess the efficacy of psoas compartment and sacral plexus block for pelvic limb amputation in dogs. Prospective clinical study. A total of 16 dogs aged 8±3 years and weighing 35±14 kg (mean±standard deviation). Dogs were administered morphine (0.5 mg kg -1 ) and atropine (0.02 mg kg -1 ); anesthesia was induced with propofol and maintained with isoflurane. Regional blocks were performed before surgery in eight dogs with bupivacaine (2.2 mg kg -1 ) and eight dogs were administered an equivalent volume of saline. The lumbar plexus within the psoas compartment was identified using electrolocation lateral to the lumbar vertebrae at the fourth-fifth, fifth-sixth and sixth-seventh vertebral interspaces. The sacral plexus, ventrolateral to the sacrum, was identified using electrolocation. Anesthesia was monitored using heart rate (HR), invasive blood pressure, electrocardiography, expired gases, respiratory frequency and esophageal temperature by an investigator unaware of the group allocation. Pelvic limb amputation by coxofemoral disarticulation was performed. Dogs that responded to surgical stimulation (>10% increase in HR or arterial pressure) were administered fentanyl (2 μg kg -1 ) intravenously for rescue analgesia. Postoperative pain was assessed at extubation; 30, 60 and 120 minutes; and the morning after surgery using a visual analog scale (VAS). The number of intraoperative fentanyl doses was fewer in the bupivacaine group (2.7±1.1 versus 6.0±2.2; pdogs at extubation (0.8±1.9 versus 3.8±2.5) and at 30 minutes (1.0±1.4 versus 4.3±2.1; pdogs.

Sacrectomy and ilio-lumbar reconstruction is an uncommonly performed complex surgical procedure for the treatment of sacral neoplasia. There are many challenges in the post-operative period including the potential for tumor recurrence, infection, and construct failure. We present our experience of this patient cohort and describe the complications and imaging appearances that can be encountered during the follow-up period. Retrospective review of our Orthopaedic Oncology database was undertaken which has been collected over a 30-year period to identify patients that had undergone sacrectomy and ilio-lumbar reconstruction. Pre and post-operative imaging including radiographs, CT, and MRI was reviewed. These were viewed by two experienced musculoskeletal radiologists with consensus opinion if there was disagreement over the imaging findings. Data regarding patient demographics, tumor type, and dimensions was collected. Serial review of radiographs, CT, and MRI was performed to assess implant position and integrity, strut graft position and union, and for the presence of recurrence within the surgical bed. Five male and two female patients (mean age 36 years, age range 15-54 years) were treated with this procedure. Histological diagnoses included chordoma, chondrosarcoma, osteosarcoma, and spindle cell sarcoma. Mean maximal tumor size on pre-operative imaging was 10.7 cm (range, 6-16 cm). Post-operative follow-up ranged from 10-46 months. A total of 76 imaging studies were reviewed. Commonly identified complications included vertical rod and cross-connector fracture and screw loosening. Fibula strut graft non-union and fracture was also evident on imaging review. Two patients demonstrated disease recurrence during the follow-up period. This study demonstrates the spectrum and frequency of complications that can occur following sacrectomy and ilio-lumbar reconstruction for sacral neoplasia. (orig.)

Shrines and relics between Late Antiquity and Middle Ages: Christianization of the space or sacralization of the Christianity?

2002-12-01

Full Text Available This essay analyzes the importance of relics and sanctuaries against the backdrop of the sacralization of Christianity and the latter’s re-elaboration into a religious system that occurred in urban milieux in the late ancient times. The main steps of this process, which came to a climax in the 4th century, are the Christianization of time and space as well as the reinterpretation of Christ’s death in terms of a sacrifice.

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. 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. Global lumbar lordosis (L1-S1) was 44.99 (± 10754) on radiographs and 47.91 (±9.170) on MRI, yielding a clinically relevant correlation (r = 0.61, p < 0.01). Measurements of single level lordosis only showed minor differences. At all levels except for L5 / S1, lordosis measured by means of standing radiographs was higher than that measured by MRI. The difference in global lumbar L1-S1 lordosis was -2.9 . Analysis of the Roussouly groups showed the largest difference for L1-S1 (-8.3 ) in group 2. In group 4, when measured on MRI, L5 / S1 lordosis (25.71 ) was lower than L4 / L5 lordosis (27.63 ) compared to the other groups. Although measurements of global lumbar lordosis significantly differed between the two scanning technologies, the mean difference was just 2.9 . MRI in supine position may be used for estimating global lumbar lordosis, but single level lordosis should be determined by means of standing radiographs.

The purpose of this study is to examine the morphological and kinematical changes of the uterus induced by electrical stimulation applied to the skin just above the second and fourth posterior sacral foramens (sacral surface electrical stimulation [ssES]) in 26 healthy subjects. Out of them, eight subjects who had severe pain subjectively during every menstruation received ssES just in menstruation. Morphological and functional changes of the uterus were examined by using T2-weighted magnetic resonance (MR) imaging and T1-weighted MR cinematography, respectively. Cyclic electrical stimulation for 15 min with 5 sec ON and 5 sec OFF was applied just before MR scanning. A decrease in thickness of the muscular layer of the uterus was observed in every subject after ssES for 15 min and was significant as compared with the thickness before ssES. Periodic uterine movement during menstruation was observed in the subjects with severe menstrual pain in MR cine and the power spectrum analysis of the movement showed a marked decrease in peak power and frequency after ssES treatment. We conclude that ssES causes a reduction of static muscle tension of the uterus in all menstrual cycle periods and suppression of uterine peristalsis during menstruation in the subjects with severe menstrual pain. Possible neural mechanisms for these static and dynamic effects of ssES on the uterus at spinal level are discussed. (author)

Batra, R K; Aseeja, Veena

2014-04-01

Vacuum-assisted closure (VAC) therapy is a new entrant in wound care after growth factors and alginate or hydrocolloid dressing, in the treatment of pressure ulcers. We have been using this technique for diabetic foot ulcers. A young nondiabetic man presented with a large sacral bed sore after high doses of ionotropes in an intensive care unit for treating severe hypotension. His wound was debrided, and instead of flap surgery in such infected wound, he was treated with VAC therapy. The complete wound healing was achieved in 6 weeks and at half the cost of flap surgery. Moreover, the chances of flap failure and its related complications were eliminated.

Case 1: The 61-year-old woman developed uterine cancer at age 50. Radiation therapy was initiated to the pelvic lumen from both anterior and posterior sides with a total dose of 21,000 rads. Radiation ulcerative enterocolitis and dermatitis revealed at the end of the therapy. At age 52 (2 years after radiation), she noticed muscle weakness and dysesthesia of the lower legs. These symptoms progressed and amyotrophy of the legs appeared. At age 54 (4 years after radiation), she became unable to walk. Case 2: The 51-year-old woman developed uterine cancer at age 40. Postoperative radiation was initiated by the same dose and the same way as in Case 1 and she suffered from radiation dermatitis. At age 49 (9 years after radiation), she noticed dysesthesia of the right toe, which gradually spread to another side. Ten years after radiation, she began to note weakness in dorsiflexion of feet. Case 3: The 69-year-old woman developed uterine cancer at age 67. Radiation (Linac 4,000 rads, Ralstron 2,000 rads) was performed for 3 months into the pelvic lumen. Two years later, she noted dysesthesia and weakness of her legs. These symptoms progressed gradually. In these 3 cases, EMG showed neurogenic changes, suggesting peripheral nerve lesions. Nerve conduction velocities were decreased. Nerve and muscle biopsies revealed neurogenic changes. No abnormal findings were detected by spinal X-rays and myelography. The neurological findings of these patients were compatible with the lumbo-sacrol plexus injuries apparently due to late radiation effect. (J.P.N.).

Patients in critical care areas are at risk for developing hospital-acquired pressure ulcers (HAPUs) due to their physical conditions and limited ability to reposition themselves. A prospective, 2-phase quality improvement study was conducted from September to November 2011 and from February to April 2012 in 1 medical and 1 surgical ICU to investigate the impact of a turn-and-assist device on the incidence of HAPUs and the time and personnel required to reposition patients reported as person/minutes (staff x minutes). A consecutive, convenience sample of patients was selected from newly admitted ICU patients who were at least 18 years old, nonambulatory, and required 2 or more people to assist with turning and repositioning. Sociodemographic data (patient age, gender, height, weight, body mass index, incontinence status); total Braden score and subscores for Activity, Mobility, and Moisture on admission; length of ICU stay and ventilator days; and sacral pressure ulcer incidence and stage and turn-and-assist data were collected. Fifty (50) patients participated in each phase. In phase 1, standard care for positioning included pillows, underpads, standard low-air-loss beds and additional staff as required for turning. In phase 2, the study product replaced standard care repositioning products including pillows; and a larger disposable moisture-wicking underpad (included as part of the turn study project kit) was substituted for the smaller, standard moisture-wicking disposable underpad. Turning procedures were timed with a stopwatch. Data were collected for a total of 32 hours during the observation periods; all patients were followed from admission until discharge from the ICU for a maximum of 14 days. T-tests were used to compare patient characteristics and person-minutes needed for repositioning differences, and Fisher's exact test was used to compare the incidence of sacral HAPUs during phase 1 and phase 2 of the study. No statistically significant

To characterize the effect of sacral neuromodulation (SNM) on urethral neuromuscular function. Following IRB approval, women with refractory overactive bladder (OAB) underwent standardized urethral testing prior to and after Stage 1 SNM implantation. Periurethral sensation was measured using current perception thresholds (CPT). Striated urethral sphincter activity was quantified using concentric needle electromyography (CNE) and Multi-Motor Unit Action Potential (MUP) analysis software. Nonparametric analyses were used to characterize pre/post changes with intervention. Baseline CPT and CNE findings were compared between SNM responders and non-responders. Twenty-seven women were enrolled in this pilot study with a mean age of 61 ± 13 years. Twenty of 26 women (76.9%) responded to SNM and went to Stage 2 permanent implantation. Four (14.8%) withdrew after Stage 1 implantation; three of the four withdrawals had not had therapeutic responses to SNM. CPT and CNE parameters did not significantly differ from baseline 2 weeks after SNM. Pre-SNM urethral sensation was not significantly different between responders and non-responders. However, responders had larger amplitude, longer duration and more turns and phases at baseline approaching significance, reflecting more successful urethral reinnervation, than non-responders. SNM does not alter urethral neuromuscular function 2 weeks post Stage 1 implantation. Copyright © 2012 Wiley Periodicals, Inc.

2010-01-01

Objective: To explore the diagnostic value of MRI on fetal neural tube defects. Methods: Ten pregnant women, aged from 25 to 35 years (average 28 years) and with gestation from 20-39 weeks (average 33 weeks) were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound (US) studies. The imaging protocol included fast-imaging employing steady-state acquisition, single-shot FSE and T 1 -weighted fast inversion recovery motion insensitive sequences in the axial, fromtal, and sagittal planes relative to the fetal brain, thorax, abdomen, and spines. Prenatal US and MRI findings were compared with postnatal MRI diagnoses (3 fetuses) or autopsy (7 fetuses). Results: Ten pregnant women (9 with a single fetus and 1 with twin fetuses) were examined. For all cases, the diagnoses established by MRI were correct when compared with postnatal diagnosis or autopsy. In 7 cases, US and MRI findings were in complete agreement with postnatal diagnoses. US missed the diagnosis in 1 cases and misdiagnosed in 2 cases. Ten neural tube defects in this study included anencephaly (1 case), exencephaly (1 case), meningoencephalocele associated with amniotic band sequence (1 case), meningocele (1 case), thoracic myelomeningocele (1 case), lumbar spinal bifida (1 case), sacroiliac myelomeningocele (2 cases), sacroiliac large cystic spinal meningocele (1 case), sacroiliac spinal bifida (1 case). Conclusions: Prenatal MRI is effective in the assessment of fetal neural tube defects. It can exactly discriminate herniated contents and locate the spinal lesion level. (authors)

Transcutaneous spinal direct current stimulation of the lumbar and sacral spinal cord: a modelling study

Fernandes, Sofia R.; Salvador, Ricardo; Wenger, Cornelia; de Carvalho, Mamede; Miranda, Pedro C.

2018-06-01

Objective. Our aim was to perform a computational study of the electric field (E-field) generated by transcutaneous spinal direct current stimulation (tsDCS) applied over the thoracic, lumbar and sacral spinal cord, in order to assess possible neuromodulatory effects on spinal cord circuitry related with lower limb functions. Approach. A realistic volume conductor model of the human body consisting of 14 tissues was obtained from available databases. Rubber pad electrodes with a metallic connector and a conductive gel layer were modelled. The finite element (FE) method was used to calculate the E-field when a current of 2.5 mA was passed between two electrodes. The main characteristics of the E-field distributions in the spinal grey matter (spinal-GM) and spinal white matter (spinal-WM) were compared for seven montages, with the anode placed either over T10, T8 or L2 spinous processes (s.p.), and the cathode placed over right deltoid (rD), umbilicus (U) and right iliac crest (rIC) areas or T8 s.p. Anisotropic conductivity of spinal-WM and of a group of dorsal muscles near the vertebral column was considered. Main results. The average E-field magnitude was predicted to be above 0.15 V m-1 in spinal cord regions located between the electrodes. L2-T8 and T8-rIC montages resulted in the highest E-field magnitudes in lumbar and sacral spinal segments (>0.30 V m-1). E-field longitudinal component is 3 to 6 times higher than the ventral-dorsal and right-left components in both the spinal-GM and WM. Anatomical features such as CSF narrowing due to vertebrae bony edges or disks intrusions in the spinal canal correlate with local maxima positions. Significance. Computational modelling studies can provide detailed information regarding the electric field in the spinal cord during tsDCS. They are important to guide the design of clinical tsDCS protocols that optimize stimulation of application-specific spinal targets.

AIM: To investigate the response of astrocytes and neurons in rat lumbo-sacral spinal cord and medulla oblongata induced by chronic colonic inflammation, and the relationship between them. METHODS: Thirty-three male Sprague-Dawley rats were randomly divided into two groups: experimental group (n = 17), colonic inflammation was induced by intra-luminal administration of trinitrobenzenesulfonic acid (TNBS); control group (n = 16), saline was administered intra-luminally. After 3, 7, 14, and 28 d of administration, the lumbo-sacral spinal cord and medulla oblongata were removed and processed for anti-glial fibrillary acidic protein (GFAP), Fos and GFAP/Fos immunohistochemistry. RESULTS: Activated astrocytes positive for GFAP were mainly distributed in the superficial laminae (laminae I-II) of dorsal horn, intermediolateral nucleus (laminae V), posterior commissural nucleus (laminae X) and anterolateral nucleus (laminae IX). Fos-IR (Fos-immunoreactive) neurons were mainly distributed in the deeper laminae of the spinal cord (laminae III-IV, V-VI). In the medulla oblongata, both GFAP-IR astrocytes and Fos-IR neurons were mainly distributed in the medullary visceral zone (MVZ). The density of GFAP in the spinal cord of experimental rats was significantly higher after 3, 7, and 14 d of TNBS administration compared with the controls (50.4±16.8, 29.2±6.5, 24.1±5.6, P0.05). CONCLUSION: Astrocytes in spinal cord and medulla oblongata can be activated by colonic inflammation. The activated astrocytes are closely related to Fos-IR neurons. With the recovery of colonic inflammation, the activity of astrocytes in the spinal cord and medulla oblongata is reduced. PMID:16097052

Objective evaluation by reflectance spectrophotometry can be of clinical value for the verification of blanching/non blanching erythema in the sacral area.

Early detection of non blanching erythema (pressure ulcer category I) is necessary to prevent any further skin damage. An objective method to discriminate between blanching/non blanching erythema is presently not available. The purpose of this investigation was to explore if a non invasive objective method could differentiate between blanching/non blanching erythema in the sacral area of patients undergoing hip fracture surgery. Seventy-eight patients were included. The sacral area of all patients was assessed using (i) conventional finger-press test and (ii) digital reading of the erythema index assessed with reflectance spectrophotometry. The patients were examined at admission and during 5 days postsurgery. Reflectance spectrophotometry measurements proved able to discriminate between blanching/non blanching erythema. The reliability, quantified by the intra-class correlation coefficient, was excellent between repeated measurements over the measurement period, varying between 0·82 and 0·96, and a significant change was recorded in the areas from day 1 to day 5 (P < 0·0001). The value from the reference point did not show any significant changes over the same period (P = 0·32). An objective method proven to identify early pressure damage to tissue can be a valuable tool in clinical practice. © 2013 The Authors.

Sakakibara, Ryuji; Yamanishi, Tomonori; Uchiyama, Tomoyuki; Hattori, Takamichi

2006-08-01

Both neurologists and urologists might encounter patients with acute urinary retention due to benign inflammatory nervous diseases. Based on the mechanism of urinary retention, these disorders can be divided into two subgroups: disorders of the peripheral nervous system (e.g., sacral herpes) or the central nervous system (e.g., meningitis-retention syndrome [MRS]). Laboratory abnormalities include increased herpes virus titers in sacral herpes, and increased myelin basic protein in the cerebrospinal fluid (CSF) in some cases with MRS. Urodynamic abnormality in both conditions is detrusor areflexia; the putative mechanism of it is direct involvement of the pelvic nerves in sacral herpes; and acute spinal shock in MRS. There are few cases with CSF abnormality alone. Although these cases have a benign course, management of the acute urinary retention is necessary to avoid bladder injury due to overdistension. Clinical features of sacral herpes or MRS differ markedly from those of the original "Elsberg syndrome" cases.

Spine fusions can be performed through different techniques and are used to treat a number of vertebral pathologies. However, there seems to be no consensus regarding which technique of fusion is best suited to treat each distinct spinal disease or group of diseases. To study the effectiveness and complications of the different techniques used for spinal fusion in patients with lumbar spondylosis. Systematic literature review and meta-analysis. Randomized clinical studies comparing the most commonly performed surgical techniques for spine fusion in lumbar-sacral spondylosis, as well as those reporting patient outcome were selected. Identify which technique, if any, presents the best clinical, functional, and radiographic outcome. Systematic literature review and meta-analysis based on scientific articles published and indexed to the following databases: PubMed (1966-2009), Cochrane Collaboration-CENTRAL, EMBASE (1980-2009), and LILACS (1982-2009). The general search strategy focused on the surgical treatment of patients with lumbar-sacral spondylosis. Eight studies met the inclusion criteria and were selected with a total of 1,136 patients. Meta-analysis showed that patients who underwent interbody fusion presented a significantly smaller blood loss (p=.001) and a greater rate of bone fusion (p=.02). Patients submitted to fusion using the posterolateral approach had a significantly shorter operative time (p=.007) and less perioperative complications (p=.03). No statistically significant difference was found for the other studied variables (pain, functional impairment, and return to work). The most commonly used techniques for lumbar spine fusion in patients with spondylosis were interbody fusion and posterolateral approach. Both techniques were comparable in final outcome, but the former presented better rates of fusion and the latter the less complications. Copyright © 2011 Elsevier Inc. All rights reserved.

Garre's chronic diffuse sclerosing osteomyelitis of the sacrum: a rare condition mimicking malignancy.

LENUS (Irish Health Repository)

Nasir, N

2012-02-03

Garre\\'s chronic diffuse sclerosing osteomyelitis (DSOM) is a rare disease that occurs most commonly in the mandible. We present a case of sacral DSOM that simulated an expanding destructive sacral tumour. Treatment was conducted on the basis of the available experience with the mandibular form of the disease, with partial symptomatic relief, but progressive sclerosis of the sacral lesion. To the best of our knowledge, this is the first case initially presenting in the sacrum. As an osteolytic expanding lesion simulating malignancy, it is important to recognize this entity in the sacrum.

2006-01-01

Between April 2002 and December 2005, we treated 15 patients who were suffering from pre-sacral recurrence of rectal cancer with or without liver metastases, using multi-portal irradiation and oral intake of tegafur-uracil (UFT) (300 mg/day), to assess pain relief and local control. Radiation therapy was given 2.1 to 2.4 Gy daily fractions, and total tumor dose was set up at a landmark of 66 Gy/30 fractions/6 weeks (time-dose-fractionation (TDF)=115, corresponding to 70 Gy), varying by recurrent tumor volume. The follow-up time was ranged from 3 to 37 months (median=14.7 months), and median survival was 14.8 months. Pain remission time was 3 to 36 months (median=10.4 months). No severe morbidity which induced by radiation therapy was observed in follow-up duration. The median survival has become unfavorite, but the multi-portal irradiation of high dose delivery is useful for improvement of quality of life (QOL) and beneficial as a palliative therapy. To improvement of local control and prognosis, combined modality with more effective regimen of chemotherapy is expected. (author)

Our aim was to determine the impact of pregnancy on sacral neuromodulation (SNM) and vice versa in patients with Fowler's syndrome (FS), which is typified by chronic urinary retention (CUR). We performed a retrospective study of pregnancy in patients with FS who underwent a two-stage SNM implantation. Data were obtained using a standard questionnaire and clinical interview. There were a total of ten patients with 13 pregnancies. The SNM was switched off in ten of the 13 pregnancies, with CUR recurring in nine of the ten pregnancies and recurrent urinary tract infections (UTI) occurring in four of these pregnancies (more than three UTI in the pregnancy). Those in whom the device was left on continued to void normally. One woman had a first trimester miscarriage, eight pregnancies went to term, and four deliveries were premature. Caesarean section was performed in eight pregnancies for obstetric reasons. Four pregnancies resulted in a vaginal delivery. There were no congenital anomalies reported. Following delivery, four of nine women experienced dysfunction of their SNM device when it was switched back on. Turing off the SNM during pregnancy results in recurrence of CUR, with an increased risk of recurrent UTI associated with preterm delivery. This did not impact foetal well-being. The option of keeping the SNM on during pregnancy should therefore be considered, and as caesarean section affects the SNM device, we advise that caesarean section should only be performed for obstetric reasons.

Full Text Available Abstract Background Caudal regression is a rare syndrome which has a spectrum of congenital malformations ranging from simple anal atresia to absence of sacral, lumbar and possibly lower thoracic vertebrae, to the most severe form which is known as sirenomelia. Maternal diabetes, genetic predisposition and vascular hypoperfusion have been suggested as possible causative factors. Case presentation We report a case of caudal regression syndrome diagnosed in utero at 22 weeks' of gestation. Prenatal ultrasound examination revealed a sudden interruption of the spine and "frog-like" position of lower limbs. Termination of pregnancy and autopsy findings confirmed the diagnosis. Conclusion Prenatal ultrasonographic diagnosis of caudal regression syndrome is possible at 22 weeks' of gestation by ultrasound examination.

1996-07-01

To investigate the acute effects of functional magnetic stimulation (FMS) on detrusor hyper-reflexia using a multi-pulse magnetic stimulator. Seven male patients with established and intractable detrusor hyper-reflexia following spinal cord injury were studied. No patient was on medication and none had had previous surgery for detrusor hyper-reflexia. After optimization of magnetic stimulation of S2-S4 sacral anterior roots by recording toe flexor electromyograms, unstable detrusor activity was provoked during cystometry by rapid infusion of fluid into the bladder. The provocation test produced consistent and predictable detrusor hyper-reflexia. On some provocations, supramaximal FMS at 20 pulses/s for 5 s was applied at detrusor pressures which were > 15 cmH2O. Following FMS there was an obvious acute suppression of detrusor hyper-reflexia. There was a profound reduction in detrusor contraction, as assessed by the area under the curves of detrusor pressure with time. Functional magnetic stimulation applied over the sacrum can profoundly suppress detrusor hyper-reflexia in man. It may provide a non-invasive method of assessing patients for implantable electrical neuromodulation devices and as a therapeutic option in its own right.

Full Text Available Purpose We investigated the effects of different stimulation frequencies on the inhibition of bladder overactivity by sacral neuromodulation (SNM in pigs. Methods Implant-driven stimulators were used to stimulate the S3 spinal nerve in 13 pigs. Cystometry was performed by infusing normal saline (NS or acetic acid (AA. SNM (pulse width, 210 µsec at frequencies ranging from 5 to 50 Hz was conducted at the intensity threshold at which observable perianal and/or tail movement was induced. Multiple cystometrograms were performed to determine the effects of different frequencies on the micturition reflex. Results AA-induced bladder overactivity significantly reduced the bladder capacity (BC to 34.4%±4.7% of the NS control level (354.4±35.9 mL (P0.05, but SNM at 15, 30, and 50 Hz significantly increased the BC to 54.5%±7.1%, 55.2%±6.5%, and 57.2%±6.1% of the NS control level (P0.05. Conclusions This study demonstrated that 15 Hz was an appropriate frequency for SNM and that frequencies higher than 15 Hz did not lead to better surgical outcomes.

Full Text Available Background: Fetus-In-Fetu (FIF is a rare congenital malformation, which consists of a fetus mixed with a distinct tissue that is from the other fetus of twin. FIF is defined as a mass containing a vertebral axis often associated with other organs or limbs around this central axis.Case report: The patient was a two day old girl infant who due to a mass in a sacrum area measuring 8.5 x 12.5 cm with soft consistency containing a normal skin color fluid with blood streaks and hemorrhagic and bruise colored patches since birt, was admitted at the Taleghani children's Pediatric Center of Gorgan. The results of the mother's ultrasound in the fourth month of pregnancy had identified the cyst for the fetus. In the primary results of imaging, the first the diagnosis was type 2 sacrocoxigeal teratoma. However, results of post-birth graphy confirmed the presence of fetal bone structure in the infants's sacrum, so FIF was diagnosed for the infant.Conclusion: In the present study, FIF has been seen in sacrum, which is a very rare case in FIF.

3D Volumetric Modeling and Microvascular Reconstruction of Irradiated Lumbosacral Defects After Oncologic Resection

Directory of Open Access Journals (Sweden)

Emilio Garcia-Tutor

2016-12-01

Full Text Available Background: Locoregional flaps are sufficient in most sacral reconstructions. However, large sacral defects due to malignancy necessitate a different reconstructive approach, with local flaps compromised by radiation and regional flaps inadequate for broad surface areas or substantial volume obliteration. In this report, we present our experience using free muscle transfer for volumetric reconstruction in such cases, and demonstrate 3D haptic models of the sacral defect to aid preoperative planning.Methods: Five consecutive patients with irradiated sacral defects secondary to oncologic resections were included, surface area ranging from 143-600cm2. Latissimus dorsi-based free flap sacral reconstruction was performed in each case, between 2005 and 2011. Where the superior gluteal artery was compromised, the subcostal artery was used as a recipient vessel. Microvascular technique, complications and outcomes are reported. The use of volumetric analysis and 3D printing is also demonstrated, with imaging data converted to 3D images suitable for 3D printing with Osirix software (Pixmeo, Geneva, Switzerland. An office-based, desktop 3D printer was used to print 3D models of sacral defects, used to demonstrate surface area and contour and produce a volumetric print of the dead space needed for flap obliteration. Results: The clinical series of latissimus dorsi free flap reconstructions is presented, with successful transfer in all cases, and adequate soft-tissue cover and volume obliteration achieved. The original use of the subcostal artery as a recipient vessel was successfully achieved. All wounds healed uneventfully. 3D printing is also demonstrated as a useful tool for 3D evaluation of volume and dead-space.Conclusion: Free flaps offer unique benefits in sacral reconstruction where local tissue is compromised by irradiation and tumor recurrence, and dead-space requires accurate volumetric reconstruction. We describe for the first time the use of

Case report 491: Stress fracture of the right sacrum

A case of stress fracture of the right sacrum in a postpartum woman has been presented. Key features in making the diagnosis include a history of pain in the sacrum, considerable weight gain during the pregnancy and pronounced increased physical activity in the immediate postpartum period. CT, particularly, and MRI were critical in making the diagnosis. A low signal area on the T-1 neglected image was considered characteristic for the sacral fracture. In the CT studies a vertical lucency thru a zone of sclerosis is classical for a fracture, whether an insufficiency fracture or a fatigue fracture.

The diagnosis and management of pediatric cerebrospinal fluid (CSF) leak and encephalocele are challenging. The current study aimed to identify patient characteristics, review operative techniques, and evaluate the efficacy and safety of endoscopic endonasal repair in a pediatric population. We retrospectively reviewed the records of pediatric patients who underwent transnasal endoscopic repair of CSF leak with or without a meningocele or an encephalocele at Beijing Tongren Hospital, Capital Medical University, between July 2003 and May 2014. All patients had preoperative radiological evaluations and underwent endoscopic endonasal repair of their skull base defects. Altogether, 23 children (mean age 7.0 years) underwent the procedures. Sixteen cases were congenital, and 7 patients had trauma history. The herniations or defects included meningoencephaloceles in 15 cases, meningoceles in 4 cases, and CSF leak in 4 cases (2 patients had bilateral leaks). The leak or herniation sites were ethmoid roof in 10 patients (one was bilateral), cribriform plate in 5, lateral to the foramen cecum in 3, posterior wall of the frontal sinus in 1, sphenoid sinus in 2, lateral recess of the sphenoid sinus in 1, and sella turcica base in 2. All subjects had favorable clinical outcomes without recurrence during a follow-up of 6-123 months (mean 61.1 months). The endoscopic endonasal approach was the preferred method for repairing CSF leaks with or without an encephalocele in pediatric patients. Compared to traditional operations, this endoscopic procedure is minimally invasive, efficient, and safe.

Congenital high airway obstruction syndrome (CHAOS) is a rare and potentially fatal entity resulting from complete or near complete developmental airway obstruction. Although most reported cases of CHAOS are sporadic, the condition may also be associated with certain syndromes and a variety of cervical masses. Meningocele and myelomeningocele have not yet been reported in association with CHAOS.

Pressure sores are often observed in patients who are bedridden. They can be a severe problem not only for patients and their caregivers but also for plastic surgeons. Here, we describe a new method of superior gluteal artery perforator flap harvesting and anchoring with the assistance of intraoperative indocyanine green fluorescent angiography. In this report, we describe the procedure and outcomes for 19 patients with grades III and IV sacral pressure sores who underwent the operation between September 2015 and November 2016. All flaps survived, and two experienced wound-edge partial dehiscence. With the assistance of this imaging device, we were able to acquire a reliable superior gluteal artery perforator flap and perform modified operations with it that are safe, easy to learn and associated with fewer complications than are traditional. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Cephaloceles are congenital malformations characterized by externalization of the meninges and/or brain tissue through a congenital skull bone defect. In developed countries, this malformation is rare but in our developing countries, this pathology remains one of our concerns. To describe the epidemiological, clinical and therapeutic aspects of the cephaloceles. A retrospective study was conducted from 2007 to 2013 on all cases of cephalocele supported in the department of neurosurgery of the Yalgado Ouédraogo University Teaching Hospital of Ouagadougou. The malformations were supplemented by CT scan. All patients were operated. The surgical procedure in cephaloceles of the convexity consisted of a direct approach. Sincipital cephaloceles were operated by transcranial approach or combined approach associating transcranial and transnasal approaches. Fifty patients were gathered during the 7-year period. There were 18 boys and 32 girls. The ages ranged from 1 day to 11 years. The cephaloceles were located on the vault of the skull in 78%; the lesion was sincipital in 22%. The malformation was covered with normal skin in 92%; it was pediculated in 78%. CT scan allowed the classification of cases as meningo-encephaloceles in 31 cases (62%) and meningoceles in 18 cases (36%) and one pure encephalocele. The immediate postoperative course was uneventful in 42 cases (84%); 8 postoperative deaths were recorded. At medium and long term, 4 patients (8%) developed complications of psychomotor deficiency in 3 cases and hydrocephalus in 1 case. The main reasons for the poor prognosis were superinfection, hydrocephalus and/or other brain malformations. Cephaloceles remain relatively frequent in our practice. After surgery, mental failure and hydrocephalus can occur impairing the prognosis. The most suitable solution is a policy of prevention with folic acid treatment before and during pregnancy and following up adequate pregnancies. Copyright © 2015 Elsevier Masson SAS. All

Intraosseous pneumatocyst of the ilium: CT findings in two cases and literature review

1997-01-01

Intraosseous pneumatocyst of the ilium is a rare lesion of uncertain origin. It predilects male subjects and may be associated or not with sacroiliac joint degenerative disease, intra-articular gas, sacral pneumatocyst, and communication with the articular space. To our knowledge, only 16 observations have been reported in the literature. We have evaluated with plain radiographs and CT two additional cases. Plain films frequently identify these lesions, but CT is the method of choice in demonstrating their air density and assessing the possible abnormalities of the surrounding bone and sacroiliac joints.

2010-01-01

Deep sequencing of small RNAs isolated from human sacral ganglia latently infected with herpes simplex virus 2 (HSV-2) was used to identify HSV-2 microRNAs (miRNAs) expressed during latent infection. This effort resulted in the identification of five distinct HSV-2 miRNA species, two of which, miR-H3/miR-I and miR-H4/miR-II, have been previously reported. Three novel HSV-2 miRNAs were also identified, and two of these, miR-H7 and miR-H9, are derived from the latency-associated transcript (LAT) and are located antisense to the viral transcript encoding transactivator ICP0. A third novel HSV-2 miRNA, miR-H10, is encoded within the unique long (U(L)) region of the genome, 3' to the U(L)15 open reading frame, and is presumably excised from a novel, latent HSV-2 transcript distinct from LAT.

Full Text Available Aim: to study influence of traction therapy in a pulse mode in a complex with electrotherapy on a condition of blood circulation of the bottom extremities and level of a metabolic exchange. Material and methods. There had been examined 120 patients with a lumbar and sacral dorsopathy aged from 22 to 69 years (middle age of 49,5 years with prescription of a disease from 1 to 5 years, among them men of 34,2%, women of 65,8%. Results. The analysis of effects of various medical methods on a condition of local blood circulation in the bottom extremities showed that the most expressed its compensation is noted at complex application of mechanical pulse traction influence and electrotherapy for patients with a dorsopathy of lumbar and sacral department of a backbone that is confirmed by restoration to normal values of all indicators rheovasogramm. Conclusion. High clinical results of application of the combined medical and rehabilitation complex are based on compensation of local blood circulation that is shown in elimination of deficiency of blood supply due to improvement of a tone of arterial vessels and elimination of venous stagnation, and also due to increase of linear speed of a blood-groove and development of collateral blood circulation. Application of electrical impulse and mechanical traction influences, more at their combination promotes fermentative activity of the systems responsible for a protein exchange that is important for prevention of degenerate and dystrophic process progressing.

To determine whether sacral neuromodulation (SNM) for urinary symptoms or fecal incontinence gives improvement of female sexual function and whether improvement is due to physiological or psychological factors. Between 2002 and 2008, 8 patients had an array of questionnaires before and after SNM implantation. The questionnaires were: the Questionnaire for Screening for Sexual Dysfunctions, the Golombok Rust Inventory of Sexual Satisfaction, the Symptom Checklist-90, the Maudsley Marital Questionnaire and the McGill-Mah Orgasm Questionnaire. Three of these 8 patients underwent vaginal plethysmography before and after implantation. No statistically significant changes were found, although there seems to be a trend toward improvement in orgasm scores. In plethysmography all 3 patients showed increased vaginal pulse amplitude with the stimulator turned on with both erotic and non-erotic stimuli. This study does not show a clear effect of SNM on sexual function, although there seems to be an improvement in orgasm scores. The lack of response on psychological questionnaires and the increase in vaginal pulse amplitude after SNM implantation indicate that there might be a physiological response. Copyright © 2012 S.

Objective. Our goal is to develop an interface that integrates chronic monitoring of lower urinary tract (LUT) activity with stimulation of peripheral pathways. Approach. Penetrating microelectrodes were implanted in sacral dorsal root ganglia (DRG) of adult male felines. Peripheral electrodes were placed on or in the pudendal nerve, bladder neck and near the external urethral sphincter. Supra-pubic bladder catheters were implanted for saline infusion and pressure monitoring. Electrode and catheter leads were enclosed in an external housing on the back. Neural signals from microelectrodes and bladder pressure of sedated or awake-behaving felines were recorded under various test conditions in weekly sessions. Electrodes were also stimulated to drive activity. Main results. LUT single- and multi-unit activity was recorded for 4-11 weeks in four felines. As many as 18 unique bladder pressure single-units were identified in each experiment. Some channels consistently recorded bladder afferent activity for up to 41 d, and we tracked individual single-units for up to 23 d continuously. Distension-evoked and stimulation-driven (DRG and pudendal) bladder emptying was observed, during which LUT sensory activity was recorded. Significance. This chronic implant animal model allows for behavioral studies of LUT neurophysiology and will allow for continued development of a closed-loop neuroprosthesis for bladder control.

The aim of this study was to try to understand if psychological evaluation of patients candidate to sacral nerve stimulation (SNS) could be a potential selection criterion to identify those patients who could successfully respond to this treatment. From 2005 to 2007, 68 patients with slow transit constipation were identified, and all of them fulfill the selection criteria for the SNS treatment. The MMPI-2 test was purposed to all the patients. Wexner score, bowel movements, and SF36 were recorded in all the patients. Twenty-three patients (33.8%) refused the psychological evaluation. Forty-five patients completed the test: only 13 patients (19.1%) had a score in the normal range of the scales of the MMPI-2 and were implanted with the temporary test for SNS. After the screening period, 11 patients (84.6%) reported more than 50% improvement of bowel movements per week and no need of laxatives, so they were definitively implanted. The mean follow-up period was 22 months (range 12-36). The mean number of bowel movements per week and Wexner score were significantly improved after 1 year (p < 0.001). A complete and accurate psychological evaluation could be very important in the selection of the patients with STC that could benefit from SNS.

Peripheral injury of pelvic visceral sensory nerves alters GFRa (GDNF family receptor alpha localization in sensory and autonomic pathways of the sacral spinal cord

Directory of Open Access Journals (Sweden)

Shelley Lynne Forrest

Full Text Available GDNF (glial cell line-derived neurotrophic factor, neurturin and artemin use their co-receptors (GFRα1, GFRα2 and GFRα3, respectively and the tyrosine kinase Ret for downstream signalling. In rodent dorsal root ganglia (DRG most of the unmyelinated and some myelinated sensory afferents express at least one GFRα. The adult function of these receptors is not completely elucidated but their activity after peripheral nerve injury can facilitate peripheral and central axonal regeneration, recovery of sensation, and sensory hypersensitivity that contributes to pain. Our previous immunohistochemical studies of spinal cord and sciatic nerve injuries in adult rodents have identified characteristic changes in GFRα1, GFRα2 or GFRα3 in central spinal cord axons of sensory neurons located in dorsal root ganglia. Here we extend and contrast this analysis by studying injuries of the pelvic and hypogastric nerves that contain the majority of sensory axons projecting to the pelvic viscera (e.g., bladder and lower bowel. At 7 d, we detected some effects of pelvic but not hypogastric nerve transection on the ipsilateral spinal cord. In sacral (L6-S1 cord ipsilateral to nerve injury, GFRα1-immunoreactivity (IR was increased in medial dorsal horn and CGRP-IR was decreased in lateral dorsal horn. Pelvic nerve injury also upregulated GFRα1- and GFRα3-IR terminals and GFRα1-IR neuronal cell bodies in the sacral parasympathetic nucleus that provides the spinal parasympathetic preganglionic output to the pelvic nerve. This evidence suggests peripheral axotomy has different effects on somatic and visceral sensory input to the spinal cord, and identifies sensory-autonomic interactions as a possible site of post-injury regulation.

Bosch, J L; Groen, J

1998-05-01

The aim of this study was to determine the urodynamic effects of sacral (S3) nerve stimulation in patients with urge incontinence due to detrusor overactivity which has been refractory to conservative treatment. A total of 24 patients with idiopathic detrusor instability and five with neurogenic hyperreflexia were studied urodynamically before and 6 months after a permanent S3 foramen electrode implant. The urodynamic studies at follow-up were done with the stimulus on. Clinically, the average voiding frequency, the number of leakage episodes and pad use per 24 h decreased significantly. Improvement in several urodynamic parameters was noted. In the idiopathic as well as in the neurogenic group, the correlation between symptomatic and urodynamic improvement was incomplete. Neuromodulation leads to improvement of several urodynamic parameters in patients with urge incontinence due to detrusor overactivity which has been refractory to conservative treatment and appears to be a valuable treatment option in these patients.

Full Text Available Pilonidal cysts and sinuses are described as dermoid cysts which contain follicles of hairs and sebaceous glands. They clinically present as a classic case of inflammation which comes with pain, local infection and redness. The origin of pilonidal disease remains controverse. There are many hypothesis as lack of hygiene on the affected area and a penetration and growth of a hair in the subcutaneus tissue caused by constant friction or direct trauma on the damaged area. The option for clinical treatment is very frequent. However, taking into consideration the incidence and the possibility of recidive, surgical treatment is presently recommended. Complications include cellulitis and abscess formation. Pilonidal cysts are mostly found on the sacral region. In the literature is found description of pilonidal cysts on the penis, interdigital region on the hands as well as on the cervical region. We present a case of pilonidal cyst located on the vault biparietal region, without malignant degeneration.

The purpose of this study was to describe our experience to be realizing Sacral colpopexia in patients with prolapso of cupola from March 1991 to August 1996 and to compare our results with the written in the National and International literature, cause at least in our country the reports and the number of patients that are included in thus kind of surgery are fex, even in hospitals with great concentration. Twelve women were attended which age were average 52 years old, multiparity in 83.3% of these cases and all of them with the story of hysterectomy. In the 58.3% the symptoms produced by the prolapse were presented was sensation of rare body and to give up the sexual activity in the patients that got in before of the prolapse was emerged. In 5 patients (41.6%) also this symptomatology was accompanied by incontinence urinary of stress because of were demonstrated in them the debility of the anterior vaginal wall and for this reason was realized Sacral colpopexy plus operation of Burch at the same surgical time. A mersilene No. 5 material was used in order to set the vaginal cupola to the anterior ligament of the sacral an a "bridge" of the additional reinforce with the same material. Were not emerged transoperatory complications. The following of our patients after surgery had been from 6 month to 6 years (depending on the year in which was the surgery) and sexual activity reset in the patients has been identified got it before the prolapse, and by the other side a new prolapse is not presented in the patients of the study. We establishes surgical preventive rules to avoid the prolapse of cupola in patients that are emerged to hysterectomy, vaginal or abdominal.

Full Text Available Giant cell tumour (GCT is an uncommon primary bone tumour, and its multicentric presentation is exceedingly rare. We report a case of a 45-year-old female who presented to us with GCT of left distal radius. On the skeletal survey, osteolytic lesion was noted in her right sacral ala. Biopsy confirmed both lesions as GCT. Pulmonary metastasis was also present. Resection-reconstruction arthroplasty for distal radius and thorough curettage and bone grafting of the sacral lesion were done. Multicentric GCT involving distal radius and sacrum with primary sacral involvement is not reported so far to our knowledge.

To explore the common types of massive intraoperative bleeding, clinical characteristics, treatment philosophy and operating skills in pelvic cancer surgery. We treated massive intraoperative bleeding in 19 patients with pelvic cancer in our department from January 2003 to March 2012. Their clinical data were retrospectively analyzed. The clinical features of massive intraoperative bleeding were analyzed, the treatment experience and lessons were summed up, and the operating skills to manage this serious issue were analyzed. In this group of 19 patients, 7 cases were of presacral venous plexus bleeding, 5 cases of internal iliac vein bleeding, 6 cases of anterior sacral venous plexus and internal iliac vein bleeding, and one cases of internal and external iliac vein bleeding. Six cases of anterior sacral plexus bleeding and 4 cases of internal iliac vein bleeding were treated with suture ligation to stop the bleeding. Six cases of anterior sacral and internal iliac vein bleeding, one cases of anterior sacral vein bleeding, and one case of internal iliac vein bleeding were managed with transabdominal perineal incision or transabdominal cotton pad compression hemostasis. One case of internal and external iliac vein bleeding was treated with direct ligation of the external iliac vein and compression hemostasis of the internal iliac vein. Among the 19 patients, 18 cases had effective hemostasis. Their blood loss was 400-1500 ml, and they had a fair postoperative recovery. One patient died due to massive intraoperative bleeding of ca. 4500 ml. Most of the massive intraoperative bleeding during pelvic cancer surgery is from the presacral venous plexus and internal iliac vein. The operator should go along with the treatment philosophy to save the life of the patient above all, and to properly perform suture ligation or compression hemostasis according to the actual situation, and with mastered crucial operating hemostatic skills.

Muscle-splitting approach to superior and inferior gluteal vessels: versatile source of recipient vessels for free-tissue transfer to sacral, gluteal, and ischial regions.

Science.gov (United States)

Park, S

2000-07-01

The superior gluteal vessel has been reported as a recipient in free-tissue transfer for the coverage of complex soft-tissue defects in the lumbosacral region, where a suitable recipient vessel is difficult to find. The characteristics of proximity, vessel caliber, and constancy make the superior gluteal vessel preferable to previously reported recipient vessels. However, there are technical difficulties in microsurgery (e.g., short pedicle length and deep location) and muscle injury (transection of the muscle) associated with use of the superior gluteal vessel. The purpose of this article is to present a modification of an approach to the gluteal vessel to alleviate technical difficulties and minimize muscle injury. From August of 1997 to January of 1999, six patients received microvascular transfer of the latissimus dorsi muscle or myocutaneous flap to the sacral (4) and ischial (2) regions. The causes of defects were tumor (1), trauma (1), and pressure sores (4). A muscle-splitting approach was used on the superior gluteal vessel and was later applied to the inferior gluteal vessel. The gluteus maximus muscle was split as needed in the direction of its fibers, and the perforators were dissected down to the superior or inferior gluteal artery and vein deep into the muscle. The follow-up period ranged from 6 to 22 months, and all of the flaps survived with complete recovery of the lesion. The major drawbacks of using the superior and inferior gluteal vessels can be overcome with the muscle-splitting approach, which provides increased accessibility and additional length to the vascular pedicle while causing minimal injury to the muscle itself. It also proves to be an easy, safe, and reliable method of dissection. When free-tissue transfer to sacral, gluteal, and ischial regions is indicated, the muscle-splitting approach to the superior and inferior gluteal vessels is a recommended option in the selection of a recipient vessel.

Purpose: Treatment of spine and sacral chordoma generally involves surgical resection, usually in conjunction with radiation therapy. In certain circumstances where resection may result in significant neurologic or organ dysfunction, patients can be treated definitively with radiation therapy alone. Herein, we report the outcome and the assessment of tumor response to definitive radiation therapy. Methods and Materials: A retrospective analysis was performed on 40 patients with unresected chordoma treated with photon/proton radiation therapy. Nineteen patients had complete sets of imaging scans. The soft tissue and bone compartments of the tumor were defined separately. Tumor response was evaluated by the modified Response Evaluation Criteria in Solid Tumors (RECIST) and volumetric analysis. Results: With a median follow-up time of 50.3 months, the rates of 5-year local control, overall survival, disease-specific survival, and distant failure were 85.4%, 81.9%, 89.4%, and 20.2%, respectively. Eighty-four computed tomographic and magnetic resonance imaging scans were reviewed. Among the 19 patients, only 4 local failures occurred, and the median tumor dose was 77.4 GyRBE. Analysis at a median follow-up time of 18 months showed significant volumetric reduction of the total target volume (TTV) and the soft tissue target volume (STTV) within the first 24 months after treatment initiation, followed by further gradual reduction throughout the rest of the follow-up period. The median maximum percentage volumetric regressions of TTV and STTV were 43.2% and 70.4%, respectively. There was only a small reduction in bone target volume over time. In comparison with the modified RECIST, volumetric analysis was more reliable, more reproducible, and could help in measuring minimal changes in the tumor volume. Conclusion: These results continue to support the use of high-dose definitive radiation therapy for selected patients with unresected spine and sacral chordomas

Full Text Available Any new clinical data, whether positive or negative, generated about a medical device should be published because health professionals should know which devices do not work, as well as those which do. We report three spinal cord injury patients in whom urological implants failed to work. In the first, paraplegic, patient, a sacral anterior root stimulator failed to produce erection, and a drug delivery system for intracavernosal administration of vasoactive drugs was therefore implanted; however, this implant never functioned (and, furthermore, such penile drug delivery systems to produce erection had effectively become obsolete following the advent of phosphodiesterase type 5 inhibitors. Subsequently, the sacral anterior root stimulator developed a malfunction and the patient therefore learned to perform self-catheterisation. In the second patient, also paraplegic, an artificial urinary sphincter was implanted but the patient developed a postoperative sacral pressure sore. Eight months later, a suprapubic cystostomy was performed as urethral catheterisation was very difficult. The pressure sore had not healed completely even after five years. In the third case, a sacral anterior root stimulator was implanted in a tetraplegic patient in whom, after five years, a penile sheath could not be fitted because of penile retraction. This patient was therefore established on urethral catheter drainage. Later, infection with Staphylococcus aureus around the receiver block necessitated its removal. In conclusion, spinal cord injury patients are at risk of developing pressure sores, wound infections, malfunction of implants, and the inability to use implants because of age-related changes, as well as running the risk of their implants becoming obsolete due to advances in medicine. Some surgical procedures such as dorsal rhizotomy are irreversible. Alternative treatments such as intermittent catheterisations may be less damaging than bladder stimulator in

Recurring priapism may be a symptom of voiding dysfunction – case report and literature review

Full Text Available ABSTRACT Recurring priapism is rare in pre-pubertal children and may be attributed to multiple causes. We propose that voiding dysfunction (VD may also justify this symptom and detail a clinical case of recurring stuttering priapism associated to overactive bladder that completely resolved after usage of anticholinergics and urotherapy. Sacral parasympathetic activity is responsible for detrusor contraction and for spontaneous erections and a relationship between erections and bladder status has been proved in healthy subjects (morning erections and models of medullar trauma. High bladder pressures and/or volumes, voiding incoordination and posterior urethritis can potentially trigger reflex erections.

Radioimmunoassay of Herpes simplex virus antibody: correlation with ganglionic infection

Results of herpes simplex virus (HSV) isolation from a series of human post-mortem trigeminal thoracic and sacral ganglia were correlated with HSV antibody type(s) detected in the sera by radioimmunoassay (RIA). HSV type I was isolated from trigeminal ganglia of 44 out of 90 individuals, from thoracic ganglia of 1 out of 25, and from sacral ganglia of 1 out of 68 cases. HSV type was recovered from sacral ganglia of 8 out of 68 individuals. In all cases in which an HSV was isolated from ganglia and was available for testing, homologous, type-specific antibody was demonstrable, and in a few instances antibody to the heterologous HSV was also detected. In those individuals in which HSV type I was isolated from trigeminal ganglia and HSV type 2 from sacral ganglia, antibody to both virus types was present in the sera, indicating that simultaneous latent infections with each of the two viruses can occur, and that antibody is produced to each virus independently. Antibody to HSV type 1, 2 or both types was demonstrated in 8 out of 10 cases in which virus isolation attempts were negative, suggesting either a higher sensitivity of RIA for detecting HSV infection, or the presence of latent HSV at some other site in the body which was not sampled.

Full Text Available A 22-year-old female, a known case of neurofibromatosis 1 (NF1, presented with a congenital swelling in the left occipital region. She had developed recent onset dysphagia and localized occipital headache. Neuroradiology revealed a left occipital meningoencephalocele and a left parapharyngeal meningocele. This was associated with ventriculomegaly. She was advised on cranioplasty along with duraplasty which she denied. She agreed to a lumbar-peritoneal shunt. She described a dramatic improvement in her symptoms following the lumbar-peritoneal shunt. Occipital dysplasias, though uncommon, have been reported in the literature. We review this case and its management and discuss relevant literature on occipital dysplasias in NF1.

SU M M A R Y In the 21st century Western society has seen an increasing interest in topics related to religion. In this context, the connection between the concept of sacrality in Western culture and freedom of verbal and artistic expression has been reconsidered; the very possibility of so-called sacred art within Western culture has been called into question. Already in the 20th century several theatrical movements in the West have expressed the need to strive for religious (or at least quasi-religious goals by means of the stage. This can already be seen in the work of the symbolists, but such experiments accelerated and became more forceful under the influence of Antonin Artaud’s visions and under the aegis of intercultural theatre. In all of these different quests one can find common elements: discontent with the discursivity of the theatrical canon, a need for a metaphysical dimension in the theatre, and the belief that channels of perception can be opened through contact with exotic ritual cultures. In his book Sacred Theatre Ralph Yarrow has attempted to define the criteria of sacrality in the theatre, drawing upon William S. Haney�

Introduction: Castellvi Type III lumbosacral transitional vertebrae (LSTV) is an unusual case of Bertolotti’s syndrome (BS) due to extraforaminal stenosis, especially manifesting in elderly patients. Case Report: We report a case of BS in a 62 years old Greek female. The signs of the clinical examination are low back pain, sciatica, hypoesthesia, and pain to the contribution of L5 nerve. Imaging techniques revealed an LSTV Type III a (complete sacralization between LSTV and sacrum). Conclusion: Despite the fact that LSTV is a congenital lesion, the clinical manifestation of BS may present in the elderly population. The accumulative effect of the gradual degeneration of intervertebral foramen (stenosis) may lead to the compression of extraforaminal portion of the nerve root. PMID:29051870

The purpose of this study was to predict the possibility of transverse iliosacral (TIS) screw fixation into the first sacral segment (S 1 ) and introduce practical anatomical variables using conventional computed tomography (CT) scans. A total of 82 cadaveric sacra (42 males and 40 females) were used for continuous 1.0-mm slice CT scans, which were imported into Mimics ® software to produce a three-dimensional pelvis model. The anterior height (BH) and superior width (BW) of the elevated sacral segment was measured, followed by verification of the safe zone (SZ S1 and SZ S2 ) in a true lateral view. Their vertical (VD S1 and VD S2 ) and horizontal (HD S1 and HD S2 ) distances were measured. VD S1 less than 7mm was classified as impossible sacrum, since the transverse fixation of 7.0 mm-sized IS screw could not be done safely. Fourteen models (16.7%; six females, eight males) were assigned as the impossible sacrum. There was no statistical significance regarding gender (p=0.626) and height (p=0.419). The average values were as follows: BW, 31.4mm (SD 2.9); BH, 16.7mm (SD 6.8); VD S1 , 13.4mm (SD 6.1); HD S1 , 22.5mm (SD 4.5); SZ S1 , 239.5mm 2 (SD 137.1); VD S2 , 15.5mm (SD 3.0); HD S2 , 18.3mm (SD 2.9); and SZ S2 , 221.1mm 2 (SD 68.5). Logistic regression analysis identified BH (p=0.001) and HD S1 (p=0.02) as the only statistically significant variables to predict the possibility. Receiver operating characteristic curve analysis established a cut-off value for BH and HD S1 of impossible sacrum of 20.6mm and 18.6mm, respectively. BH and HD S1 could be used to predict the possibility of TIS screw fixation. If the BH exceeds 20.6mm or HD S1 is less than 18.6mm, TIS screw fixation for S 1 should not be undertaken because of narrowed SZ. Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available The dorsal cutaneous appendage or the so called human tail is a rare congenital anomaly protruding from the lumbo-sacro-coccygeal area. These caudal appendages are divided into true-tails and pseudo-tails. We report here two cases of congenital pseudo-tail with underlying spina bifida and lipo-meningocele. In this article we seek to emphasize that, as the skin and nervous systems are intimately linked by their similar ectodermal origin, a dorsal appendage may be regarded as a cutaneous marker of the underlying spinal dysraphism.

Little is known about the cost-benefit of soft silicone foam dressings in pressure ulcer (PU) prevention among critically ill patients in the emergency department (ED) and intensive care unit (ICU). A randomised controlled trial to assess the efficacy of soft silicone foam dressings in preventing sacral and heel PUs was undertaken among 440 critically ill patients in an acute care hospital. Participants were randomly allocated either to an intervention group with prophylactic dressings applied to the sacrum and heels in the ED and changed every 3 days in the ICU or to a control group with standard PU prevention care provided during their ED and ICU stay. The results showed a significant reduction of PU incidence rates in the intervention group (P = 0·001). The intervention cost was estimated to be AU$36·61 per person based on an intention-to-treat analysis, but this was offset by lower downstream costs associated with PU treatment (AU$1103·52). Therefore, the average net cost of the intervention was lower than that of the control (AU$70·82 versus AU$144·56). We conclude that the use of soft silicone multilayered foam dressings to prevent sacral and heel PUs among critically ill patients results in cost savings in the acute care hospital. © 2013 The Authors.

Full Text Available Background. We report on 19 cases of giant cell tumor of bone (GCT affecting the spine or sacrum and evaluate the outcome of different treatment modalities. Methods. Nineteen patients with GCT of the spine (=6 or sacrum (=13 have been included in this study. The mean followup was 51.6 months. Ten sacral GCT were treated by intralesional procedures of which 4 also received embolization, and 3 with irradiation only. All spinal GCT were surgically treated. Results. Two (15.4% patients with sacral and 4 (66.7% with spinal tumors had a local recurrence, two of the letter developed pulmonary metastases. One local recurrence of the spine was successfully treated by serial arterial embolization, a procedure previously described only for sacral tumors. At last followup, 9 patients had no evidence of disease, 8 had stable disease, 1 had progressive disease, 1 died due to disease. Six patients had neurological deficits. Conclusions. GCT of the axial skeleton have a high local recurrence rate. Neurological deficits are common. En-bloc spondylectomy combined with embolization is the treatment of choice. In case of inoperability, serial arterial embolization seems to be an alternative not only for sacral but also for spinal tumors.

Full Text Available Soft tissue defects of the sacroiliac area, usually can be covered by local flaps. However, for more complex defects, free flap transfers became necessary. We report a case of reconstruction with a free anterolateral thigh (ALT perforator flap for coverage of a sacroiliac bone exposure in a child. A six-years-old boy, suffered a car accident, resulting in pelvic and sacral fractures, as well as degloving injuries of the left thigh, buttocks, and trunk. The patient evolved with an unstable scar over the sacroiliac region with bone exposure. ALT free flap was performed. Left superior gluteal vessels were used as the recipient vessels. A stable coverage was achieved without complications. This is the first case reported of a free ALT perforator flap for sacroiliac coverage in the pediatric population. In cases of complex reconstruction in children, free perforator flap is a safe choice and should be considered in the algorithm of treatment.

Full Text Available Pressure sore is tissue ulceration due to unrelieved pressure, altered sensory perception, and exposure to moisture. Geriatric patients with organic problems and patients with spinal cord injuries are the high-risk groups. Soft tissues over bony prominences are the common sites for ulcer development. About 95% of pressure ulcers occur in the lower part of the body. Ischial tuberosity, greater trochanter, sacrum and heel are common sites. In addition to these, pressure sores at unusual sites like nasal alae, malar eminences, cervical region and medial side of knee have also been described. Only 1.6% of the patients present with sores in areas outside the pelvis and lower extremity. In a paraplegic patient, pressure sores are usually over extensor surface of knee and heel but pressure ulcer over popliteal fossa are extremely rare. We herein report a case of a 36-years-old diabetic and paraplegic male, who presented with multiple bed sores involving the sacral area, heels and bilateral popliteal fossa. Popliteal fossa is an unusual site for pressure sores. Only one similar case has been previously reported in the literature.

Full Text Available Introduction: VZV is an exclusively human pathogen. The primary infection typically occurs during childhood and causes varicella. As with other members of the herpes viruses’ family, VZV is noninfectious in its latent form but can reactivate at a later time to form intact virions in the involved sensory neurons. These virions then migrate to the skin through axons, spread from cell to cell, and penetrate the epidermis.Case Report: In this case a 72 years old woman with history of diabetes mellitus and hypertension is reported hospitalized because of urinary retention, weakness and parestesia in the right leg, complicated with vesiculoulcerative lesions in sacral area with distribution to the right buttock and vagina. L.P was done to confirm inflammatory radicopathy that showed aseptic meningitis and therapy started with acyclovir and prednisolone. Patient got well and discharged from the hospital.Conclusion: Motor weakness in noncranial nerve is one of the zoster complications known as zoster paresis. Weakness begins suddenly 2-3 weeks after rash and progresses to extremities. In this case 3 weeks after rash, nerve complications were observed. We recommend to do paresthesia examination of skin for eruption in all patients presented with paresis.

To develop and implement a telehealth-based model of care for spinal fractures requiring management with thoracic lumbar sacral orthoses that eliminates the need for transfer to a metropolitan tertiary referral hospital. Pre-post design observational study evaluating model of care implementation. Rural referral hospitals in a large NSW region covering metropolitan, rural and remote hospitals. Patients presenting with a thoracic or lumbar spine fracture requiring thoracic lumbar sacral orthoses management and rural clinicians caring for them. Number of patients managed in rural hospitals without transfer to a metropolitan tertiary referral hospital; length of stay and related cost efficiencies; clinicians' perceived skills, knowledge and confidence levels. Model of care was implemented with clinical and system governance processes; and educational workshops across eight rural hospitals. A total of 81 patients managed in rural hospitals under this model between July 2013 and June 2016 without transfer were included in this study. Mean length of stay reduced from nine to four days. Hospital transfers were eliminated from the patient journey, totalling 24 324 km. Workshops were attended by 71 clinicians from nine rural hospitals and survey findings indicated a significant increase in staff knowledge, skill and confidence post education. Cost efficiencies were gained by eliminating 162 inter-hospital transfers and 405 patient bed days. This model has streamlined patient journeys and reduced transfers and travel, enabling rural clinicians to provide specialised services in local communities and facilitating timely evidence-based care in local communities without any adverse events. © 2018 National Rural Health Alliance Ltd.

Malignant transformation of mediastinal mature teratoma is extremely rare and worsens the prognosis of the disease. Transformation can appear synchronously to or several years after the initial diagnosis. Clinical and radiological signs can orientate the clinician but the definitive diagnosis is obtained thanks to histology. An 11 year-old boy presented with a mediastinal mature teratoma and bone and pulmonary metastases. He received six cycles of chemotherapy combining etoposide, ifosfamide, cisplatin, followed by resection of a 16×14×9cm mediastinal mass. Karyotype analysis revealed the presence of an additional sex chromosome X (47 XXY) pathognomonic of Klinefelter's syndrome. Ten years later, sciatalgia revealed malignant transformation of a pre-existing sacral bone metastasis into gastrointestinal adenocarcinoma. The patient received four cycles of chemotherapy combining oxaliplatin, 5-fluorouracil and cetuximab. This treatment was followed by a complete resection of the sacral metastasis and completed with adjuvant irradiation of 54Gy in 30 daily fractions. Twelve months after the diagnosis of relapse, the patient remained alive without disease. To our knowledge, this is the first case of adenocarcinoma developed in bone metastases of a mediastinal mature teratoma in a boy with a Klinefelter's syndrome. We propose a review of the literature and an analysis of 20 others published cases of mediastinal teratoma with malignant transformation into adenocarcinoma.

Total Knee Arthroplasty in Alkaptonuric Ochronosis: the First Case Report in Thailand and Literature Review

Directory of Open Access Journals (Sweden)

Witchuree Wejjakul

2016-09-01

Full Text Available Ochronosis is a musculoskeletal manifestation found in alkaptonuria which is a rare autosomal reces- sive disorder caused by the deficiency of homogentistic acid oxidase enzyme. This leads to accumulation and deposition of homogentistic acid (HGA pigments in skin, sclera, tendon, ligament and cartilage. Ochronosis is asymptomatic until ochronotic arthropathy occurs. We reported a case of 64-year female presented with advanced degenerative changes in the knee, hip, shoulder and lumbo-sacral spine. The operative findings during total knee arthroplasty showed bluish-black discoloration of the entire articular surface. Her urine HGA level was extremely high. Histopathological exam confirmed ochronosis. The literature, differential diagnosis and management of this rare condition are reviewed.

Radiological study. To asses standard values, intra- and interobserver reliability and reproducibility of sacral slope (SS) and lumbar lordosis (LL) and the correlation of these parameters in patients with lumbar spinal stenosis (LSS). Anteroposterior and lateral X-rays of the lumbar spine of 102 patients with LSS were included in this retrospective, radiologic study. Measurements of SS and LL were carried out by five examiners. Intraobserver correlation and correlation between LL and SS were calculated with Pearson's r linear correlation coefficient and intraclass correlation coefficients (ICC) were calculated for inter- and intraobserver reliability. In addition, patients were examined in subgroups with respect to previous surgery and the current therapy. Lumbar lordosis averaged 45.6° (range 2.5°-74.9°; SD 14.2°), intraobserver correlation was between Pearson r = 0.93 and 0.98. The measurement of SS averaged 35.3° (range 13.8°-66.9°; SD 9.6°), intraobserver correlation was between Pearson r = 0.89 and 0.96. Intraobserver reliability ranged from 0.966 to 0.992 ICC in LL measurements and 0.944-0.983 ICC in SS measurements. There was an interobserver reliability ICC of 0.944 in LL and 0.990 in SS. Correlation between LL and SS averaged r = 0.79. No statistically significant differences were observed between the analyzed subgroups. Manual measurement of LL and SS in patients with LSS on lateral radiographs is easily performed with excellent intra- and interobserver reliability. Correlation between LL and SS is very high. Differences between patients with and without previous decompression were not statistically significant.

Arthrogryposis - case report

Full Text Available Arthrogryposis is a congenital disorder characterized by multiple joint contractures found throughout the body at birth. We present the case of a 3.5 year-old girl with multiple congenital defects: arthrogryposis involving bilateral hip, knee and ankle joints, together with sacral agenesis and with lumbar dysmorphism, anorectal agenesis, hydronephrosis of the left kidney as the result from reflux, right kidney hypoplasia, renal fusion and heart anomalies: tetralogy of Fallot. Immediately after birth, in several steps, colostomy, left ureterocystoneostomy and suprapubic cystostomy were performed. Later in infancy corrective surgery for the heart defect was required. At the age of 2 years, surgery for the equinovarus deformities and for left genu flexum was performed. Medical rehabilitation tries to maximize independent function. The main goals were increasing the muscle tonus of upper-limbs, increase the rate of motion of the joints, establishment of stability for ambulation, learning different schemes of movement according to her needs, obtaining of a functional independency. The therapies were successful, after 10 weeks an improvement of the moving capacity and of the transfer in orthostatism with minimal external assistance, with the obvious increasing of the patient's satisfaction, were noticed.

De Carvalho, Diana; Grondin, Diane; Callaghan, Jack

2017-10-01

The purpose of this study was to determine which office chair feature is better at improving spine posture in sitting. Participants (n = 28) were radiographed in standing, maximum flexion and seated in four chair conditions: control, lumbar support, seat pan tilt and backrest with scapular relief. Measures of lumbar lordosis, intervertebral joint angles and sacral tilt were compared between conditions and sex. Sitting consisted of approximately 70% of maximum range of spine flexion. No differences in lumbar flexion were found between the chair features or control. Significantly more anterior pelvic rotation was found with the lumbar support (p = 0.0028) and seat pan tilt (p < 0.0001). Males had significantly more anterior pelvic rotation and extended intervertebral joint angles through L1-L3 in all conditions (p < 0.0001). No one feature was statistically superior with respect to minimising spine flexion, however, seat pan tilt resulted in significantly improved pelvic posture. Practitioner Summary: Seat pan tilt, and to some extent lumbar supports, appear to improve seated postures. However, sitting, regardless of chair features used, still involves near end range flexion of the spine. This will increase stresses to the spine and could be a potential injury generator during prolonged seated exposures.

Fifteen patients with sacral lesions were assessed using CT and volumetric 3D image rendering. Lesions imaged included sacral fractures, tumors, osteomyelitis, dysplasia, and sacroiliac diastasis. In all cases, transaxial CT alone was superior to conventional radiographs, and CT with 3D was more clinically useful than CT alone. The 3D real-time video format allows rotation and manipulation in several planes, including the X (spinal) and Z (somersaulting) axes, for optimal visualization of abnormalities. The Z axis gives unique unimpeded inlet, outlet, and ''bird's-eye'' views of the pelvis and sacrum, enhancing detection and characterization of sacral of SI disruptions and subsequent pelvic ring compromise. Because of the ease of assimilating information in such a format, 3D may become the key modality for preoperative planning and for postoperative follow-up

Glioblastoma is the most common primary malignant brain tumor. Extraneural metastases are rarely reported in the literature. We report a case of a 38-year-old patient who was diagnosed with glioblastoma in 2015. Four months after surgery, local relapse was found and the patient received a second surgery. After another 4 months, we found a hard mass in the right posterior neck when she admitted to our department for fourth cycle of adjuvant chemotherapy. Immunohistochemical investigation supported the diagnosis of glioblastoma metastases to the neck after resection of the right neck mass. A few days later, spinal vertebral magnetic resonance imaging (MRI) confirmed multiple metastases in the thoracic, lumbar, sacral, and bilateral iliac bones. Glioblastoma is the most common primary malignant brain tumor. Whole tumor resection and early radiotherapy and chemotherapy can delay recurrence and prolong survival. Extracranial metastases are extremely rare. We report this case with the aim of bringing attention to extracranial metastasis of brain glioma.

To determine the prevalence of etiologic causes of primary amenorrhea in Indian population. A retrospective study was performed using 102 complete medical records of women with primary amenorrhea who attended the Gynaecologic Endocrinology Clinic, Department of Obstetrics and Gynaecology, AIIMS, New Delhi from September 2012 to September 2015. Cases were analysed according to clinical profile, development of secondary sexual characteristics, physical examination, pelvic and rectal examination, X-ray of chest and lumbo-sacral spine, hormone profile, pelvic USG, MRI, and cytogenetic study including karyotype. The three most common causes of primary amenorrhea were Mullerian anomalies (47%), gonadal dysgenesis (20.5%), and hypogonadotropic hypogonadism (14.7%) in the present study. There were 3 cases of Turner syndrome (45,XO), 5 cases of Swyer's syndrome (46,XY) and 2 cases of Androgen insensitivity syndrome (46,XY). One case had pituitary macroadenoma and eight cases (7.8%) were of genital tuberculosis. The present study has currently been the largest case series of primary amenorrhea from North India. Mullerian anomaly is the most prevalent etiological factor leading to amenorrhoea followed by gonadal dysgenesis in our study. Racial, genetic and environmental factors could play role in the cause of primary amenorrhea. Copyright © 2017. Published by Elsevier B.V.

Recurrent perianal sepsis is a difficult problem to manage in colorectal surgical practice. One cause is rectal duplication cyst, a rare congenital lesion that is easily overlooked. Many cases have associated congenital defects, especially musculoskeletal anomalies, and may provide a clue to the underlying condition. Early diagnosis is important because these cysts do not resolve spontaneously and may undergo malignant change. We present two cases of middle-aged females who presented with perianal sepsis secondary to rectal duplication cyst. The first case had numerous surgical procedures for a perianal fistula during a ten-year period. She had associated sacral anomalies consistent with Currarino syndrome. The second case presented with a perineal mass after a bout of perianal inflammation. Both cases had the entire cyst surgically excised. There were no complications postoperatively and no recurrence at follow-up. Histopathology revealed no malignancy in the cyst. Rectal duplication cyst is a rare cause of recurrent perianal sepsis that should be considered in difficult cases, especially in those with associated musculoskeletal anomalies. Complete surgical excision is the preferred treatment to prevent recurrence and the risk of malignant degeneration.

A case of prenatal diagnosis of fetal hydantoin syndrome by ultrasound

Full Text Available Fetal hydantoin syndrome (FHS is a set of disruptions occasionally present in fetuses exposed in utero to phenytoin or other anticonvulsants. Administration of phenytoin in early pregnancy may impair proper psychomotor performance expected for children's development. Several combined phenotypic markers delineate the syndrome, but the presence of single clinical signs is more common. There is controversy about the etiology of FHS. Associated disruptions may be related to a deficiency in a detoxifying enzyme (epoxide hydrolase, vascular problems, and/or factors not yet known. Genetic causes are believed to influence susceptibility to the drug. This text reports an unusual pattern of malformations detected in an ultrasound scan (gastroschisis, sacral meningomyelocele, and absence of the right lower limb and in the anatomopathological study (left-side gastroschisis, sacral meningomyelocele, scoliosis, left clubfoot, absence of the right lower limb, and pectus carinatum of a fetus whose mother took phenytoin. These defects may have been provoked by exposure to the drug during embryogenesis. In view of similar malformations observed in cases of prenatal exposure to cocaine, a recognized vasoconstrictor, it is suggested that vascular disruptions of hemodynamic origin constituted the event leading to some of the anomalies caused in the developing embryo. A complication of the chorionic villus sampling procedure, used for cytogenetic analysis, is another possibility.A síndrome da hidantoína fetal consiste em um conjunto de disrupturas por vezes observadas em fetos expostos à fenitoína ou outros anticonvulsivos no período pré-natal. A administração de fenitoína em fase precoce da gravidez pode prejudicar o desempenho psicomotor esperado no desenvolvimento infantil. Diversos indicadores fenotípicos, em conjunto, caracterizam a síndrome, mas a presença de sinais clínicos isolados é mais comum. Há controvérsia quanto à sua etiologia. As

Full Text Available Abscesses are a rare complication of transanal minimally invasive surgery and transanal endoscopic micro surgery. Reported cases have been in the rectal and pre-sacral areas and have been managed with either antibiotics alone or in conjunction with laparotomy and diverting colostomy. We report a case of a large retroperitoneal abscess following a Transanal minimally invasive surgery full thickness rectal polyp excision. The patient was successfully managed conservatively with antibiotics and a percutaneous drain. Retroperitoneal infection should be included in a differential diagnosis following a Transanal minimally invasive surgery procedure as the presentation can be insidious and timely intervention is needed to prevent further morbidity. Resumo: Os abscessos são uma complicação rara da cirurgia de ressecção transanal minimamente invasiva (TAMIS e da micro cirurgia endoscópica transanal (TEMS. Os casos notificados foram nas áreas rectal e pré-sacral e foram administrados com antibióticos isoladamente ou em conjunto com laparotomia e desvio de colostomia. Relatamos um caso de grande abscesso retroperitoneal após uma excisão de pólipo retal de espessura total TAMIS. O paciente foi tratado com sucesso com a administração de antibióticos e drenagem percutânea.

We are presenting a prenatally diagnosed case with sirenomelia, vestigial tail and polydactyly. A 30-year-old woman at 16 weeks of gestation with dichorionic twins was admitted to the hospital. Prenatal ultrasound demonstrated fusion of the lower limbs in one member and normal femurs, tibias and fibulas, and normal vertebras in the second twin, suggesting the diagnosis of sirenomelia. The twins were delivered vaginally at 35 weeks after spontaneous onset of labor. The affected newborn died after 24 hours and postnatal examination revealed unseparated lower limbs with extreme retroversion, bilateral pes equinus, unilateral postaxial polydactyly, a vestigial tail on the sacral region, a large and wide penis and anal atresia. There is only one previous report of sirenomelia with vestigial tail in the literature. However, a large, wide penis and polydactyly have not been reported before in association with this anomaly.

Pelvic congestion syndrome is a well-known cause of cyclic pelvic pain (Ganeshan et al., Cardiovasc Intervent Radiol 30(6):1105-11, 2007). What is much less well known is that dilated or malformed branches of the internal or external iliac vessels can entrap the nerves of the sacral plexus against the pelvic sidewalls, producing symptoms that are not commonly seen in gynecological practice, such as sciatica, or refractory urinary and anorectal dysfunction (Possover et al., Fertil Steril 95(2):756-8. 2011). The objective of this video is to explain and describe the symptoms suggestive of vascular entrapment of the sacral plexus, as well as the technique for the laparoscopic decompression of these nerves. Two anecdotal cases of intrapelvic vascular entrapment are used to review the anatomy of the lumbosacral plexus and demonstrate the laparoscopic surgical technique for decompression at two different sites, one on the sciatic nerve and one on the sacral nerve roots. After surgery, the patient with the sciatic entrapment showed full recovery of the sciatica and partial recovery of the myofascial pain. The patient with sacral nerve root entrapment showed full recovery with resolution of symptoms. The symptoms suggestive of intrapelvic nerve entrapment are: perineal pain or pain irradiating to the lower limbs in the absence of a spinal disorder, and lower urinary tract symptoms in the absence of prolapse of a bladder lesion. In the presence of such symptoms, the radiologist should provide specific MRI sequences of the intrapelvic portion of the sacral plexus and a team and equipment to expose and decompress the sacral nerves should be prepared.

Concurrent lumbosacral and sacrococcygeal fusion; a rare etiology of low back pain and coccygodynia?

Sacrum is a triangular bone placed in the base of the spine and formed by the synostosis of five sacral vertebrae (S1-S5). Its upper part is connected with the inferior surface of the body of L5 vertebra forming the lumbosacral joint, while its lower part is connected with the base of the coccyx forming the sacrococcygeal symphysis, an amphiarthrodial joint. The existence of four pairs of sacral foramen in both anterior and posterior surface of the sacrum is the most common anatomy. Nevertheless, supernumerary sacral foramina are possible to be created by the synostosis of lumbosacral joint or sacrococcygeal symphysis. We present a case of an osseous cadaveric specimen of the sacrum belonging to a 79-year-old Caucasian woman. A rare variation of the anatomy of the sacrum is reported; in which, the simultaneous fusion of the sacrum with both the L5 vertebra and the coccyx has created six pairs of sacral foramen. This variation should be taken into serious consideration, especially in the domain of radiology, neurosurgery, orthopaedics and spine surgery, because low back pain, coccygodynia and other neurological symptoms may emerge due to mechanical compression.

We describe herein a rare case of primary rhabdomyosarcoma (RMS) occurring in the sacrum. A 16-year-old woman presented with a 2-month history of pain in bilateral buttocks and posterior thighs. Computed tomography showed a primary tumor with bone destruction in the 2nd sacral vertebra and invasion to the 1st to 3rd vertebrae and retroperitoneal space. Histological examination of the tumor showed proliferation of spindle-shaped cells intermingled with rhabdomyoblasts in a fascicular and storiform growth pattern. Tumor cells showed immunoreactivity for vimentin, desmin, muscle-specific actin, sarcomeric actin, {alpha}-smooth muscle actin and CD99, and partial immunoreactivity for myoD1, myf-4, myogenin and myoglobin. Reverse transcription polymerase chain reaction demonstrated expression of myoD1. On the basis of the aforementioned findings, a poorly differentiated spindle cell variant of embryonal RMS was diagnosed. The patient underwent combined therapy with chemotherapy and radiotherapy, but died 17 months after incisional biopsy. The present case is instructive in differential diagnosis of primary bone tumors, and the possibility of skeletal RMS needs to be considered. (orig.)

Burnham, Robert

2010-06-01

Describe the clinical presentation, diagnostic evaluation, and successful treatment of a case of symptomatic unilateral lumbosacral junction pseudarticulation using a novel radiofrequency nerve ablation technique. A 56-year-old female patient who had suffered with low back and right upper buttock pain for 16 years experienced incomplete relief with L4/5 facet joint radiofrequency ablation. She was found to have an elongated right L5 transverse process that articulated with the sacral ala (Bertolotti's syndrome). Fluoroscopically guided local anesthetic/corticosteroid injection into the pseudarthrosis eliminated her residual right buttock pain for the duration of the local anesthetic only. Complete pain relief was achieved by injecting local anesthetic circumferentially around the posterior pseudarthrosis articular margin. Accordingly, bipolar radiofrequency strip thermal lesions were created at the same locations. Complete pain relief and full restoration of function was achieved for 16 months postprocedure. This case report describes a novel radiofrequency technique for treating symptomatic lumbosacral junction pseudarticulation that warrants further evaluation.

ROLE OF MESH REPAIR IN PELVIC ORGAN PROLAPSE, WITH PARTICULAR REFERENCE TO VAULT PROLAPSE & NULLIPAROUS PROLAPSE

Directory of Open Access Journals (Sweden)

Geeta Vandana Reddi

2017-12-01

Full Text Available BACKGROUND Pelvic organ prolapse is a common complaint in gynaecological practice. Nulliparous prolapse is seen in 2% of female population and vault prolapse in 0.5% following hysterectomy. Various surgical procedures have been described for the repair of vault prolapse e.g. transvaginal sacrospinous colpopexy, transabdominal sacral colpopexy, Le Forte's operation, colpoclesis, posterior intravaginal sling plasty etc. The introduction of synthetic mesh like Prolene, Mersilene for the repair of vault prolapse have the advantage of tensile strength. In nulliparous prolapse and uterovaginal prolapse also, the supports of uterus are weakened, so there seems to be a definite advantage of mesh repair over sling surgeries. MATERIALS AND METHODS A prospective study done in 50 patients with vault prolapse, Nulliparous prolapse and patients with UV prolapse who want to retain their menstrual and reproductive function were identified and repair of defects were done. 2 cases who underwent both hysterectomy and sacral colpopexy in two sittings were included in the study. They were followed up for a period of 6 weeks - 29 months. RESULTS In the present study, the mean age for vault prolapse was 52.14 years, mean parity was 3.36. Vault prolapses were found to be more common after abdominal hysterectomy 60.97% compared to vaginal 39.02%. Common indication for hysterectomy is pelvic organ prolapse followed by DUB in this study. The mean time between the hysterectomy and vault prolapse in this study was 5.46 years. Importance should be given to proper enterocoele repair and vault suspense time of primary surgery. In this study incidence of smoking in vault prolapse cases was 34.14% significant. In cases of sacral colpopexy for vault prolapse in this study there were no major mesh related complications and the cure rate was 97.5%. So, sacral colpopexy with prolene mesh i.e. abdominal mesh repair can be employed as the primary surgery for vault prolapse. The safety

Full Text Available In the works of all B. Kutavičius, L. Lebič and V. Tormis, one can find a pronounced inclination towards the ritual, the use of folk instruments, the idea of the circulation of life, and some sort of simulation of folk music of unidentifiable prehistoric times. These parallels raise the questions about the causes for such similarities which are connected to the socio-political situations of countries in which the composers lived and created. Therefore, it is not possible to disconnect the stylistic changes of the seventies and eighties from the desire for political and ideological liberation. All three composers responded to those trends with similar artistic solutions: they searched for mystical and sacral music of prehistoric tribes which functioned as trigger for the awakening of strong national feelings.

Full Text Available We report a 4 month old male infant, the first in order of birth of healthy first cousin consanguineous parents who has many typical features of oral-facial-digital syndrome type VI (OFDS VI including hypertelorism, bilateral convergent squint, depressed nasal bridge, and wide upturned nares, low set posteriorly rotated ears, long philtrum, gum hyperplasia with notches of the alveolar borders, high arched palate, and hyperplastic oral frenula. He has mesoaxial and postaxial, polysyndactyly which is the specific feature of OFDS VI, however the cerebellum is normal on MRI brain. He has also some rare congenital anomalies including common atrioventricular canal, hirschsprung disease, and sacral dysgenesis. This patient may have a transitional type between II and VI, a variant of type VI or a new type.

Full Text Available Background: Malignant vulvar lesions arise from premalignant vulvar intraepithelial neoplasm (VIN and occur only rarely (3–4 % of all malignancies of the female genital organs, especially in the menopause. They are associated with human papillomavirus infection. If the change is found sufficiently early and if it is properly treated, the prognosis is favourable. Methods and patients: We present a case of a 60-year-old multiparous postmenopausal woman with recurrence of the vulvar cancer. In May 1995 vulvar biopsy revealed VIN III. In February 2006 she was examined at the Oncology Institute because of expansive lesions which covered the entire area of external genitals from clitoris to the anus. On 7th March, 2006 vulvectomy with broad safety margins and right-sided lymphadenectomy were made. Histological di- agnosis revealed a well-differentiated invasive squamous cell carcinoma (FIGO II, grade I; postoperative radiotherapy followed. In February 2007, suspicious lesions reoccurred in the external genital area, the smear was negative. In December 2007 histological diagnosis of recurrent squamous cancer was made. On 7th October, 2008 the patient was admitted to the Department of Gynecology, University Medical Centre, Ljubljana. Abdominal computed tomography showed a widespread vulvar cancer, T4 in appearance, suspicious lymph nodes in the pre-sacral area and suspicious left inguinal lymph node. Metastases to the liver were not confirmed. On 28th October, 2008 total Brunschwig operation was performed (pelvic exenteration of the bladder, uterus, pelvic lymph nodes, rectum and radical vulvectomy with resection of both ramus ossis pubis, anus praeter and transposition of skin-muscle flap (m. rectus abdominis. The interdisciplinary operation, which lasted 9 hours and blood loss was 6 litres, involved gynaecologists, a urologist, a plastic surgeon, and an oncology surgeon. The histological diagnosis of a 27 × 24 cm large preparation was a moderately

The aim of this study was to describe the MRI findings and clinical observations in a fatigue stress fracture of the sacrum. In this retrospective study, 380 conscripts (53 women, 327 men; age range 18-29 years, mean age 20.7 years) who suffered from stress-related hip pain were studied with MRI of the pelvis. The findings of MRI were evaluated with regard to stress fracture of the sacrum. Thirty-one (8%) patients had MRI changes in signal intensity of the cranial part of the sacrum, extending to the first and second sacral foramina. The MRI changes in signal intensity were intermediate on T1-weighted images, and high on short tau inversion recovery or T2-weighted fat-suppressed images. A linear signal void fracture line was also seen. Multiple stress injuries to the pelvic bones were also seen in 7 of 31 (23%) patients. Five patients (16%) had bilateral sacral stress fracture. Fatigue sacral stress fractures appeared more commonly in women than in men (p<0.001). During recovery time 20 of the 31 patients underwent control MRI, and fatty marrow conversion was seen in 8 (40%) cases as high signal intensity on T1-weighted images, which disappeared 5-6 months after the onset of symptoms. Fatigue sacral stress fractures are associated with stress-related hip pain. These fractures were more common in women than in men. Other stress injuries of the pelvis may be seen simultaneously with sacral stress fractures. Signal intensity of the sacrum was normal after 5-6 months

The diagnostic value of fetal magnetic resonance imaging (MRI), performed in 42 pregnant women whose fetuses had structural abnormalities of the central nervous system identified with transabdominal ultrasonography from 1995 through 2002, was analyzed retrospectively. Half-Fourier acquisition single-shot turbo spin-echo (HASTE) T 2 -weighted imaging clearly delineated the cerebrospinal fluid (CSF) space and the malformed brain and spinal cord and provided valuable information for the diagnosis of structural abnormalities related to the CSF space, such as spina bifida with Chiari type II malformation (7 cases), colpocephaly with agenesis of the corpus callosum (7 cases), holoprosencephaly (6 cases), porencephaly (2 cases), lissencephaly with hydrocephalus (2 cases), and middle fossa arachnoid cyst (1 case). However, some difficulty was encountered in the diagnosis of rare pathologic conditions that were not related to the CSF space, such as epignathus, multiple arteriovenous fistulae, trapped suboccipital meningocele, and Turner syndrome. We conclude that HASTE T 2 -weighted imaging, which provides useful diagnostic images in a reasonable time, is a useful adjunct to ultrasonography to confirm or exclude certain abnormalities related to the CSF space.

A case of sacral herpes zoster infection in a 56-year-old man with the complication of loss of urinary voiding sensation is presented. He had typical herpes zoster eruption on the left S2 dermatome, hypalgesia of the S1-S4 dermatomes, and absence of urinary voiding sensation. There was no other urinary symptom at the first medical examination. Urinary complications associated with herpes zoster are uncommon, but two types, acute cystitis and acute retention, have been recognized. No cases of loss of urinary voiding sensation due to herpes zoster have been reported. In this case, hypalgesia of the sacral dermatomes was mild compared to the marked loss of urethral sensation. This inconsistency is explained by the hypothesis that the number of urethral fibers is very small as compared to that of cutaneous fibers, therefore, urethral sensation would be more severely disturbed than cutaneous sensation.

To assess the evidence on the validity of sacral lateral branch blocks and the effectiveness of sacral lateral branch thermal radiofrequency neurotomy in managing sacroiliac complex pain. Systematic review with comprehensive analysis of all published data. Six reviewers searched the literature on sacral lateral branch interventions. Each assessed the methodologies of studies found and the quality of the evidence presented. The outcomes assessed were diagnostic validity and effectiveness of treatment for sacroiliac complex pain. The evidence found was appraised in accordance with the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) system of evaluating scientific evidence. The searches yielded two primary publications on sacral lateral branch blocks and 15 studies of the effectiveness of sacral lateral branch thermal radiofrequency neurotomy. One study showed multisite, multidepth sacral lateral branch blocks can anesthetize the posterior sacroiliac ligaments. Therapeutic studies show sacral lateral branch thermal radiofrequency neurotomy can relieve sacroiliac complex pain to some extent. The evidence of the validity of these blocks and the effectiveness of this treatment were rated as moderate in accordance with the GRADE system. The literature on sacral lateral branch interventions is sparse. One study demonstrates the face validity of multisite, multidepth sacral lateral branch blocks for diagnosis of posterior sacroiliac complex pain. Some evidence of moderate quality exists on therapeutic procedures, but it is insufficient to determine the indications and effectiveness of sacral lateral branch thermal radiofrequency neurotomy, and more research is required.

Full Text Available Pressure sore is tissue ulceration due to unrelieved pressure, altered sensory perception, and exposure to moisture. Geriatric patients with organic problems and patients with spinal cord injuries are the high-risk groups. Soft tissues over bony prominences are the common sites for ulcer development. About 95% of pressure ulcers occur in the lower part of the body. Ischial tuberosity, greater trochanter, sacrum and heel are common sites. In addition to these, pressure sores at unusual sites like nasal alae, malar eminences, cervical region and medial side of knee have also been described. Only 1.6% of the patients present with sores in areas outside the pelvis and lower extremity. In a paraplegic patient, pressure sores are usually over extensor surface of knee and heel but pressure ulcer over popliteal fossa are extremely rare. We herein report a case of a 36-years-old diabetic and paraplegic male, who presented with multiple bed sores involving the sacral area, heels and bilateral popliteal fossa. Popliteal fossa is an unusual site for pressure sores. Only one similar case has been previously reported in the literature.

Full Text Available Literature review. In this study, we evaluated a case of primary spinal oligodendroglioma (PSO with a rare localization between L3 and S2, and also examined sixty cases in the literature in terms of demographic characteristics, clinical, radiological, and histopathological characteristics, and treatment planning. A case of PSO has been presented, and the relevant literature between 1931 and 2016 was reviewed. A total of 57 papers regarding PSO were found and utilized in this review. The main treatment options include radical surgical excision with neuromonitoring, followed by radiotherapy. Despite these treatment protocols, the relapse rate is high, and treatment does not significantly prolong survival. Oligodendrogliomas are rare among the primary spinal cord tumors. Oligodendrogliomas are predominantly found in the cervical spinal cord, thoracic spinal cord, or junctions during childhood and adulthood. Extension to the sacral region, inferior to the Conus, is very rare. Furthermore, of the sixty cases in the literature, the case we present here is the first to be reported in this particular age group. These localizations usually occur in the pediatric age group and after relapses. While for a limited number of cases the oligodendroglioma initiates in the thoracic region and reaches as far as L2, we encountered a case of an oligodendroglioma within the range of L3 to S2. Clinical findings are observed in accordance with location, and magnetic resonance imaging is the gold standard for diagnosis.

Faecal incontinence is a physically, psychologically and socially disabling condition. NICE guidance (2007) recommends surgical intervention, including sacral nerve stimulation (SNS), after failed conservative therapies. The FENIX magnetic sphincter augmentation (MSA) device is a novel continence device consisting of a flexible band of interlinked titanium beads with magnetic cores that is placed around the anal canal to augment anal sphincter tone through passive attraction of the beads. Preliminary studies suggest the FENIX MSA is safe, but efficacy data is limited. Rigorous evaluation is required prior to widespread adoption. The SaFaRI trial is a National Institute of Health Research (NIHR) Health Technology Assessment (HTA)-funded UK multi-site, parallel group, randomised controlled, unblinded trial that will investigate the use of the FENIX MSA, as compared to SNS, for adult faecal incontinence resistant to conservative management. Twenty sites across the UK, experienced in the treatment of faecal incontinence, will recruit 350 patients randomised equally to receive either SNS or FENIX MSA. Participants will be followed-up at 2 weeks post-surgery and at 6, 12 and 18 months post-randomisation. The primary endpoint is success, as defined by device in use and ≥50 % improvement in the Cleveland Clinic Incontinence Score (CCIS) at 18 months post-randomisation. Secondary endpoints include complications, quality of life and cost effectiveness. SaFaRI will rigorously evaluate a new technology for faecal incontinence, the FENIX™ MSA, allowing its safe and controlled introduction into current clinical practice. These results will inform the future surgical management of adult faecal incontinence.

We report our ultrasonographic experiences in the evaluation of small midline scalp masses. Ultrasonography was performed in four patients with midline scalp mass less than 3cm and its connecting tract into the cranialcavity. Ultrasonographic findings were correlated with pathologic results. There were three cephaloceles and one cystic lymph angioma. Two encephalomenin-goceles, located in occipital region, were mixed cystic and solid lesions and one atretic meningocele in parietal region was a solid lesion. Ultrasonogram of all three cases showed calvarial defect and connecting tract into the cranial cavity. On the contrary, a cystic lymph angioma in occipital region was a purely cystic mass without an associated calvarial defect. We suppose that ultrasonography could be a useful screening tool in the evaluation of midline scalp masses

Prenatal Evidence of Persistent Notochord and Absent Sacrum Caused by a Mutation in the T (Brachyury Gene

Directory of Open Access Journals (Sweden)

2016-01-01

Full Text Available Caudal regression syndrome (CRS is a rare congenital disorder characterized by developmental abnormalities of caudal spinal segments. To date, the etiology of CRS is unclear; sporadic cases are strongly associated with maternal diabetes, while familiar recurrence is infrequent. We describe in detail the prenatal clinical and sonographic findings of a recently described hereditary caudal regression syndrome, in four fetuses reported to be homozygous for a mutation in the T (brachyury gene. The syndrome occurred in three consanguineous, but unrelated families, originating from the same geographical area. All affected fetuses had persistence of the notochord in association with abnormal vertebral ossification, sacral agenesis, and bilateral clubfoot. These findings suggest that, in case of prenatal diagnosis of sacral agenesis, an advanced ultrasound examination should assess the vertebral ossification and the rare persistence of the notochord, in order to rule the involvement of the T gene.

Herpes zoster infection involving the sacral dermatomes has been associated with bladder dysfunction and, although rarely, with acute urinary retention. Less than 150 cases have been reported in the literature. After reviewing our institute's chart records covering a period of time dating from 1991 to 2001, we found that three of our patients had developed acute urinary retention following herpes zoster skin lesions of the S2-4 dermatomes. Herein we report our findings. These three patients had previously been found to have normal voiding status. However, at the time of complaint urodynamic studies revealed detrusor areflexia or detrusor hyporeflexia with decreased sensation of bladder filling. After micturation recovery, repeat urodynamic studies revealed detrusor pressure and bladder sensation recovery. After one to six weeks of treatment, all three patients could void spontaneously without catheterization. We found that, when treated with antiviral medication, supportive analgesics, and temporary urinary drainage, which included urethral catheterization and suprapubic cystostomy, acute urinary retention associated with herpes zoster has a generally favorable prognosis. In other words, we found that in spite of its rarity, herpes zoster induced neuropathic bladder dysfunction is reversible when treated appropriately.

[A variant of island flaps for the covering of pressure sores: the hatchet flap. Apropos of 31 cases].

Quillot, M; Lodde, J P; Pegorier, O; Reynaud, J P; Cormerais, A

1994-08-01

The authors propose a modification of the classical design of island flaps for cover of pressure sores, applied to gluteus maximus and tensor fascia lata muscles: the hatchet flap. 31 flaps have been used including 13 gluteus maximus superior flaps for sacral pressure sores, 9 gluteal inferior flaps for ischial pressure sores and 9 tensor fascia lata flaps for trochanteric pressure sores. A small partial necrosis and two cases of sepsis were observed in this series, but did not require surgical revision. The authors emphasize the value of this modification of the classical flap design, which preserves an even better musculocutaneous capital in these patients, who are often already multi-operated. The very rapid recovery of patients supports the authors' application of hatchet flaps to the surgery of pressure sores, and suggests the extension to other musculocutaneous flaps in the future.

To evaluate the feasibility and efficiency of embolization of spinal dural arteriovenous fistula (SDAVF). From December 2010 to May 2012, there were 104 cases of SDAVF were treated, and 26 cases were selected to be treated with embolization. The inclusion criteria was as follows: (1) No anterior or posterior spinal artery originated from the fistula segment; (2) The segmental artery can be catheterized with guiding or micro catheter; (3) High flow in fistula; (4) Patient's situation was not suitable for surgery or general anesthesia. Among 26 cases, there were 22 male and 4 female patients, the average age was 55.9 years (ranged from 34 to 81 years). The locations of SDAVF were 10 cases in thoracic, 9 in lumbar and 7 in sacral segment. The main symptoms were progressive numbness and weakness in both lower extremities, most cases accompanied with difficulties in urination and defecation. The average history was 17.1 months (from 1 to 156 months). ONYX-18 liquid embolic agent or Glubran-2 surgical glue were used as embolic material. The patients not cured with embolization were treated with surgery in the following 1 - 2 weeks. Follow-up evaluation was done with MRI after 3 months and DSA after 6 months, besides physical examination. Fifteen from 26 cases achieved immediate angiographic cure results: 14 in 20 cases which embolized with ONYX-18; only 1 in 6 cases with Glubran-2. Three in 10 cases of thoracic SDAVF and 12 in 16 cases of lumbar/sacral SDAVF were cured with embolization. Partially embolized cases were treated with surgical obliteration of drainage veins within 2 weeks. Cured patients experienced immediate improvement after embolization and kept getting better in the follow-up. All the patients had MRI follow-up after 3 months and DSA follow-up after 6 months. In 6 month's follow-up, MRI showed the edema and flow void signal in the spinal cord disappeared. DSA showed no fistula recurrence or remnant. There was no deterioration case in all of the embolized

We describe a term male infant of healthy non-consanguineous parents, born with congenital malformations, including bilateral cleft palate and lip, mild microphthalmia with iris coloboma and glaucoma of the right eye, and blepharophimosis with severe microphthalmia of the left eye. Spine radiograph and MRI showed first sacral hemivertebra with spina bifida, and agenesis of the 2nd, 3rd, 4th, and 5th sacral vertebrae and coccyx. Spine MRI showed caudal tethering of spinal cord at L(3) level, filum terminalis lipoma and a syringomyelia. Brain ultrasound and MRI showed hypoplasia of corpus callosum with mild dilatation of the lateral ventricles. Orbital MRI showed bilateral microphthalmia-distorted small left eyeball with posteriorly located lens, and a split vitreous body in the right eye, suggestive of primary hyperplastic vitreous. The karyotype was normal. Summary of the findings in nine cases (our case and eight published cases) support the notion that anophthalmia-plus syndrome (APS) is a distinct syndrome. Gene locus of APS is yet to be identified. (c) 2006 Wiley-Liss, Inc.

(Meth)Acrylate Occupational Contact Dermatitis in Nail Salon Workers: A Case Series.

Science.gov (United States)

DeKoven, Samuel; DeKoven, Joel; Holness, D Linn

Recently, many cases of acrylate-associated allergic contact dermatitis have appeared among nail salon workers. Common acrylate-containing products in nail salons include traditional nail polish, ultraviolet-cured shellac nail polish, ultraviolet-cured gel nails, and press-on acrylic nails. Nail salon technicians seen in the occupational medicine clinic in 2015 and 2016 were identified, and their patch test results and clinical features were summarized. Patch testing was done with the Chemotechnique (Meth)Acrylate nail series, and either the North American Standard series or the North American Contact Dermatitis Group screening series. Six patients were identified, all women, ages 38 to 58. Common presentations included erythematous dermatitis of the dorsa of the hands, palms, and forearms and fissures on the fingertips. Less common sites of eruptions included the periorbital region, cheeks, posterior ears, neck, sacral area, lateral thighs, and dorsa of the feet. All patients reacted to hydroxyethyl methacrylate, and 5 patients reacted to ethyl acrylate. Each patient also reacted to (meth)acrylates that are not found on either standard series, including ethyleneglycol dimethacrylate, 2-hydroxypropyl methacrylate, and 2-hydroxyethyl acrylate. The authors report 6 cases of allergic contact dermatitis to acrylates in nail technicians seen over the past year, representing a new trend in their clinic. These cases are reflective of a growing trend of nail technicians with allergic contact dermatitis associated with occupational (meth)acrylate exposure. Efforts to improve prevention are needed.

Clinical Usage of an Extracellular, Collagen-rich Matrix: A Case Series.

Science.gov (United States)

AbouIssa, Abdelfatah; Mari, Walid; Simman, Richard

2015-11-01

OASIS Ultra (Smith and Nephew, St. Petersburg, FL) is an extracellular, collagen-rich matrix derived from submucosa of porcine intestine. It is composed of collagen type I, glycosaminoglycan, and proteoglycans. This extracellular matrix (ECM) differs from the single layer in thickness and offers ease of handling and application. It also stimulates cell migration and structural support, provides moisture environment, decreases inflammation, and induces cell proliferation and cellular attachments. In this case series, the authors present their experience with this product in various clinical scenarios. The authors used the product in a variety of wounds with different etiologies to test the clinical outcome of the ECM. This was an observational case series with prospective review of 6 different patients with different types of wounds who received treatment with the ECM during their treatment. The product was applied on the following types of wounds: chronic venous ulcer, nonhealing Achilles tendon vasculitic wound, Marjolin's ulcer, posttraumatic wound, stage IV sacral-coccygeal pressure wound, and complicated transmetatarsal amputation of gangrenous left forefoot diabetic wound. All of these wounds healed within the expected time periods and without complications. In general, healing was achieved in 4-16 weeks using 1-12 applications of the ECM. Wounds with different etiologies were successfully treated with an extracellular, collagen-rich matrix. By replacing the lost ECM to guide cellular growth and migration, this product did ultimately hasten the healing process.

Voiding dysfunction is a rare but important complication of lumbo-sacral herpes zoster. Although the symptoms are transient, the clinical impact on immunocompromised patients cannot be overlooked. To clarify the time course of voiding dysfunction in herpes zoster, 13 herpes zoster patients with voiding dysfunction were retrospectively analyzed. Of 13 patients, 12 had background disease, and six of these were hematopoietic malignancies; four of these patients were hematopoietic stem cell transplant (HSCT) recipients. Ten patients had sacral lesions, two had lumbar, and one had thoracic lesions. Interestingly, patients with severe rash, or with hematopoietic malignancy had later onset of urinary retention than did patients with mild skin symptoms (Mann-Whitney U analysis, P = 0.053) or with other background disease (P = 0.0082). Patients with severe skin rash also had longer durations (P = 0.035). In one case, acute urinary retention occurred as late as 19 days after the onset of skin rash. In immune compromised subjects, attention should be paid to patients with herpes zoster in the lumbo-sacral area for late onset of acute urinary retention even after the resolution of skin symptoms.

This article aims to provide more insight into the presentation, diagnosis, and treatment of Bertolotti's syndrome, which is a rare spinal disorder that is very difficult to recognize and diagnose correctly. The syndrome was first described by Bertolotti in 1917 and affects approximately 4 to 8% of the population. It is characterized by an enlarged transverse process at the most caudal lumbar vertebra with a pseudoarticulation of the transverse process and the sacral ala. It tends to present with low back pain and may be confused with facet and sacroiliac joint disease. In this case report, we describe a 40-year-old man who presented with low back pain and was eventually diagnosed with Bertolotti's syndrome. The correct diagnosis was made based on imaging studies which included computed tomographic scans, plain x-rays, and magnetic resonance imaging scans. The patient experienced temporary relief when the abnormal pseudoarticulation was injected with a cocktail consisting of lidocaine and steroids. In order to minimize the trauma associated with surgical treatment, a minimally invasive approach was chosen to resect the anomalous transverse process with the accompanying pseudoarticulation. The patient did well postoperatively and had 97% resolution of his pain at 6 months after surgery. As with conventional surgical approaches, a complete knowledge of anatomy is required for minimally invasive spine surgery. This case is an example of the expanding utility of minimally invasive approaches in treating spinal disorders.

The caudal approach to the epidural space has been used for decades to treat low back pain caused by lumbosacral root compression. The use of fluoroscopy during epidural steroid injection is the preferred method for placing the needle more accurately in the sacral hiatus, but it carries the risk of radiation hazard. The aim of the study was to assess the anatomical structure of the sacral hiatus and the feasibility of caudal epidural injections under ultrasound guidance. Two hundred and forty patients (male = 100, female = 140) with low back pain and sciatica who were candidates for caudal epidural injection were enrolled into this study. Ultrasound images of the sacral hiatus and bilateral cornua were obtained by a real-time linear array ultrasound transducer. The distance between bilateral cornua and the anterior and posterior wall of the sacrum were measured at the base (sacral hiatus). Under the guide of ultrasonography, we defined the injection successful if turbulence of medication fluid was observed in the sacral canal, but correct placement of the needle and injectant was confirmed on fluoroscopic view as the gold standard technique. The epidurogram showed that the injection was successful in 230 of the 240 patients (95.8%). In eight patients, the injection was not in the correct place in the sacral canal. The sacral hiatus could not be identified by ultrasound images in only two patients who had a closed sacral hiatus identified by fluoroscopy. The mean distance of the sacral hiatus was 4.7 ± 1.7 mm and the mean distance between bilateral cornua was 18.0 ± 2.8 mm. The mean duration of the procedure was 10.8 ± 6.8 minutes. No major complication was observed in the next month. In conclusion, ultrasound could be used as a safe, fast and reliable modality to observe the anatomic variation of the sacral hiatus and to perform caudal epidural injections

Ewing's sarcoma is a primary malignancy of the bone affecting individuals in the second decade of life. Primary sarcomas of the spine are rare and the occurrence of Primary Ewing's sarcoma in the spine is very rare. Ewing's sarcoma occurring in the spine is divided into two types, Ewing's sarcoma of sacral spine which are very aggressive with poor prognosis and Ewing's sarcoma of the non sacral spine which is an extremely rare occurrence. Patient may present with neurological deficit when the tumour extends into the spinal canal causing spinal cord compression. Magnetic resonance imaging (MRI) is very sensitive in diagnosing the tumour and defining the extent of the tumour. Here we report an 18-year-old boy who presented with back pain and complete paraplegia of two months duration. The MRI gave a differential diagnosis of infective pathology due to the fluid collection in the paraspinal region, followed by primary malignancy as the second diagnosis. Patient underwent posterior spinal decompression and stabilization, and intaoperatively there was significant collection of pus whose culture showed no growth. The histopathology and immunohistochemistry studies confirmed the diagnosis of Ewing's sarcoma and patient was started on combination chemotherapy and radiotherapy.

Endoscopic endonasal surgery, an innovative surgical technique, is used to approach sinus lesions, lesions of the skull base, and intradural tumors. The cooperation of experienced otolaryngologists and neurosurgeons is important to achieve safe and reliable surgical results. The bath plug closure method is a treatment option for patients with cerebrospinal fluid(CSF)leakage. Although it includes dural and/or intradural procedures, surgery tends to be performed by otolaryngologists because its indications, detailed maneuvers, and pitfalls are not well recognized by neurosurgeons. We reviewed the cases of patients with CSF leakage treated by using the bath plug closure method with an endoscopic endonasal approach at our institution. Three patients were treated using the bath plug closure method. CSF leakage was caused by a meningocele in two cases and trauma in one case. No postoperative intracranial complications or recurrence of CSF leakage were observed. The bath plug closure method is an effective treatment strategy and allows neurosurgeons to gain in-depth knowledge of the treatment options for CSF leakage by using an endoscopic endonasal approach.

OBJECTIVE The goal of this study was to determine the significance of spinal cord anomalies (SCAs) in patients with anorectal malformations (ARMs) by comparing the outcomes for bowel function, lower urinary tract symptoms (LUTS), and lower-limb neurological abnormalities to these outcomes in patients with similar ARMs and a normal spinal cord. METHODS The spinal cord MRI records of female patients treated for vestibular and perineal fistula (VF/PF) and male patients with rectourethral fistula (RUF) at a single center between 1983 and 2006 were reviewed. Bowel function and LUTS were assessed by questionnaire. Patients with extensive sacral anomalies or meningomyelocele were excluded. RESULTS Of 89 patients (median age 15 years, range 5-29 years), MRI was available in 90% (n = 80; 40 male patients with RUF), and 80% of patients returned the questionnaire (n = 64; 31 male patients with RUF). Spinal cord anomalies were found in 34%, comprising a filum terminale lipoma in 30%, low conus medullaris in 10%, and thoracolumbar syrinx in 6%. Bowel functional outcomes between patients with SCAs (n = 23) and those with a normal spinal cord (n = 41) were not significantly different for soiling (70% vs 63%), fecal accidents (43% vs 34%), and constipation (57% vs 39%; p = not significant for all). The LUTS, including urge (65% vs 54%), urge incontinence (39% vs 24%), stress incontinence (17% vs 22%), and straining (32% vs 29%) were also comparable between groups (p = not significant for all). No patients developed lower-limb neurological abnormalities. CONCLUSIONS The results suggest that the long-term functional outcomes for patients with SCAs who had VF/PF and RUF may not differ significantly from patients with the same type of ARMs and a normal spinal cord. The results favor a conservative approach to their management in the absence of abnormal neurological findings in the lower limbs.

Sacral nerve stimulation (SNS) reduces symptoms in up to 80% of patients with faecal incontinence (FI). Its effects are not limited to the distal colon and the pelvic floor. Accordingly, spinal or supraspinal neuromodulation have been suggested as part of the mode of action. The effect of SNS on gastric and small-intestinal motility was studied. Using the magnet tracking system, MTS-1, a small magnetic pill was tracked twice through the upper gastrointestinal tract of eight patients with FI successfully treated with SNS. Following a randomized double-blind crossover design, the stimulator was either left active or was turned off for 1 week before investigations with MTS-1. The median (range) frequency of gastric con-tractions was 3.05 (2.83-3.40) per min during SNS and 3.04 (2.79?-3.76) per min without (P=NS). The median (range) frequency of contractions in the small intestine during the first 2h after pyloric passage was 10.005 (9.68-10.70) per min during SNS and 10.09 (9.79-10.29) per min without SNS (P=NS). The median (range) velocity of the magnetic pill during the first 2h in the small intestine was 1.6 (1.2-2.8) cm/min during SNS and 1.7 (0.8-3.7) cm/min without SNS (P=NS). Small-intestinal propagation mainly occurred during very fast movements (>15cm/min), accounting for 51% (42-60%) of the distance 3% (2-4%) of the time during SNS and for 53% (18-73%) of the distance 3% (1-8%) of the time without SNS (P=NS). Turning off SNS for 1week did not affect gastric or small-intestinal motility patterns. © 2012 The Authors. Colorectal Disease © 2012 The Association of Coloproctology of Great Britain and Ireland.

Sirenomelia is a rare anomaly that rarely occurs as an isolated lesion. Several theories have been proposed regarding the etiopathogenesis. In this communication, we report a case of sirenomelia. Our patient was referred to hospital at the age of four hours. On examination, fusion of both lower limbs with hook shaped appendage, attached distally, absent genitalia and absent anal orifice was found. Spine was deficient in sacral region. Upper torso looked normal. Baby also had frothing from mouth. Abdomen was non-distended. Feeding tube no.10 was tried to pass through mouth, which got obstructed at the level of upper esophagus that suggested oesophageal atresia. The skeletogram revealed absence of pelvic bones, sacral agenesis, absent fibulae and fracture of both femora. The patient died at the age of 12 hours.

Small bowel obstruction in percutaneous fixation of traumatic pelvic fractures

Directory of Open Access Journals (Sweden)

Roberto Bini

2013-01-01

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.

Diprosopus (Greek; di-, "two" + prosopon, "face"), or craniofacial duplication, is a rare craniofacial anomaly referring to the complete duplication of facial structures. Partial craniofacial duplication describes a broad spectrum of congenital anomalies, including duplications of the oral cavity. This paper describes a 15 month-old female with a duplicated oral cavity, mandible, and maxilla. A Tessier type 7 cleft, midline meningocele, and duplicated hypophysis were also present. The preoperative evaluation, surgical approach, postoperative results, and a review of the literature are presented. The surgical approach was designed to preserve facial nerve innervation to the reconstructed cheek and mouth. The duplicated mandible and maxilla were excised and the remaining left maxilla was bone grafted. Soft tissue repair included closure of the Tessier type VII cleft. Craniofacial duplication remains a rare entity that is more common in females. The pathophysiology remains incompletely characterized, but is postulated to be due to duplication of the notochord, as well as duplication of mandibular growth centres. While diprosopus is a severe deformity often associated with anencephaly, patients with partial duplication typically benefit from surgical treatment. Managing craniofacial duplication requires a detailed preoperative evaluation as well as a comprehensive, staged treatment plan. Long-term follow up is needed appropriately to address ongoing craniofacial deformity. Published by Elsevier Ltd.

There are relatively few reports of sacral stress fractures in children. In adolescents, sacral stress fractures have been reported in patients involved in vigorous athletic activity. Recognition of these fractures is important to avoid unnecessary biopsy if the findings are confused with tumor or infection. We report a sacral fatigue fracture in a 15-year-old without a history of athletic participation or trauma. (orig.)

Neurolymphomatosis is a rare condition defined as an infiltration of nerves, nerve roots or nervous plexuses by haematological malignancy. Its diagnosis may sometimes be difficult with conventional imaging techniques. This paper aims to emphasize the importance of this entity and the role of (18)F-FDG PET/CT in this indication. We present the case of a 53-year-old male who complained of sharp pain in his right hip and right leg paresthesia after 2 years of complete remission from Non-Hodgkin's lymphoma. Physical examination and CT scan were negative and the lumbar MRI showed protrusion of L5-S1 disc. Physiotherapy, nonsteroid antiinflammatory drugs and steroids were inefficient. PET/CT was performed four months after the onset of the symptoms, revealing focal FDG uptake in the right S1 nerve root and linear FDG uptake along the right sacral plexus suggesting relapse. This was confirmed by histology. Copyright © 2013 Elsevier España, S.L. and SEMNIM. All rights reserved.

Impact of Local Management on Long-Term Outcomes in Ewing Tumors of the Pelvis and Sacral Bones: University of Florida Experience

Purpose: This retrospective analysis describes our 35-year experience with respect to disease control and functional status. Patients and Methods: Thirty-five patients with localized Ewing tumors of the pelvis and sacral bones were treated from 1970 to 2005. Twenty-six patients were treated with definitive radiotherapy (RT), and 9 patients were treated with combined local therapy in the form of surgery + RT. The median RT dose was 55.2 Gy. The patients who received RT alone were more likely to be older men with larger tumors exhibiting soft-tissue extension. Patients in the definitive RT group were more likely to receive etoposide and ifosfamide or undergo bone marrow transplant. Median potential follow-up was 19.4 years. Results: The 15-year actuarial cause-specific survival, freedom from relapse rate, and local control rates were 26% vs. 76% (p = 0.016), 28% vs. 78% (p = 0.015), and 64% vs. 100% (p = 0.087), respectively, for patients treated with definitive RT and combined therapy. Overall, tumors <8 cm had significantly better cause-specific survival, but this was unrelated to local control. The median Toronto Extremity Salvage Score for the definitive RT and combined therapy groups were 99 and 94, respectively (p = 0.19). Seven definitive RT patients (27%) had serious complications. Conclusion: Combined modality local therapy should be considered if pelvic Ewing tumors are resectable. However, because of the extent of local disease, most patients have unresectable or partially resectable tumors and therefore require RT in some capacity. For this reason, innovative RT strategies are needed to improve long-term disease outcomes and minimize side effects while maintaining an acceptable functional result

Prospective multicenter observation. To determine the validity of 3 commercially available at recording thoracic-lumbar-sacral orthosis (TLSO) wearing time of children with spinal cord injury (SCI) and to assess each monitor's function during daily activities. A major limitation to studies assessing the effectiveness of spinal prophylactic bracing is the patient's compliance with the prescribed wearing time. Although some studies have begun to use objective compliance monitors, there is little documentation of the validity of the monitors during activities of daily life and no comparisons of available monitors. Fifteen children with SCI who wore a TLSO for paralytic scoliosis were observed for 4 days during their rehabilitation stay. Three compliance monitors (2 temperature and 1 pressure sensitive) were mounted onto each TLSO. Time of brace wear from the monitors was compared with the wear time per day recorded in diaries. Observed versus monitored duration of brace wear found the HOBO (temperature sensitive) to be the most valid compliance monitor. The HOBO had the lowest average of difference and variance of difference scores. The correlation between the recorded daily entries and monitored brace wear time was also highest for the HOBO in analysis of dependent and independent scores. Bland-Altman plots showed that the pressure sensitive monitor underestimated wear time whereas the temperature monitors overestimated wear time. Compliance to prescribed wearing schedule has been a barrier to studying TLSO efficacy. All 3 monitors were found to measure TLSO compliance, but the 2 temperature monitors were more in agreement with the daily diaries. Based on its functional advantages compared with the HOBO, the StowAway TidbiT will be used to further investigate the long-term compliance of TLSO bracing in children with SCI.

To explore the relative prognostic factors of Tile C pelvic injury after iliolumbar fixation. Between March 2007 and March 2010, 60 patients with Tile C pelvic injuries were surgically treated with iliolumbar fixation, including 39 males and 21 females with an average age of 37 years (range, 17-66 years). Of them, 27 cases were classified as Tile C1, 20 as Tile C2, and 13 as Tile C3. The preoperative injury severity score (ISS) was 12-66 (mean, 29.4). The time from injury to surgery was 2-25 days (mean, 8.1 days). Iliolumbar fixation was performed in all patients. Unconditional logistic analysis was used to analyze the relationship between the age, sex, body mass index (BMI), operation opportunity, the preoperative combined injury, classification of fracture, the postoperative complication, reduction outcome, sacral nerve injury, and the time of physical exercise and the prognosis. All 60 patients were followed up 12-56 months (mean, 27.3 months). Infection of incisions occurred in 12 cases and were cured after dressing change; healing of incision by first intention was obtained in the other patients. Delay sacral nerve injury was found in 15 patients, 6 patients underwent nerve decompression, and 9 underwent conservative treatment. Ten patients had nail protrusion of Schanz screws at the posterior superior illac spine, and 3 patients had pain, which was relieved after removal of the internal fixator. One patient had bone-grafting nonunion of sacroiliac joint, which was improved by pressured bone graft. Five patients had the beam breakage without significant effect. Six patients had deep vein thrombosis, among them 4 underwent filter and 2 underwent nonsurgical treatment. The healing time of fracture was 3-6 months (mean, 3.9 months). According to the Matta function score, the results were excellent in 31 cases, good in 24 cases, fair in 3 cases, and poor in 2 cases with an excellent and good rate of 91.7% at last follow-up. Majeed score was 58-100 (mean, 86), 28

A case of neurofibromatosis developing facial paralysis following treatment with a gamma knife

Hosomi, Yoshikazu [Kobe Rosai Hospital (Japan)

2002-12-01

Neurofibromatosis is generally classified into types I and II: the latter may be life-threatening when the acoustic nerve tumor becomes enlarged. The author reports on a patient with bilateral acoustic nerve tumors, as well as large tumors at the neck and sacral regions, who developed facial nerve paralysis following surgery in which a gamma knife was used. The patient, a 30-year-old woman with no family history of neurofibromatosis, had a prominent neurofibroma at the pharyngeal region surgically removed when she was about 23. The procedure left her with dysfunctions of the vocal cords and lingual movements. At the age of 30 (March 2001), a tumor originating at S1 of the sacral nerve plexus was removed, which caused her leg movements to be restricted. Later, an acoustic nerve tumor was found to have enlarged; and in July 2001, the left acoustic nerve tumor was extirpated by using a gamma knife. Starting in early 2002, her left facial movements appeared to be compromised but during the follow-up observation period, she regained the movements. Patients with neurofibromatosis are often plagued by the development of multiple tumors and surgical sequelae. One is reminded that it is necessary to plan treatment with sufficient consideration given to quality of life (QOL) (including the problem of an acoustic nerve tumor that may develop in future) as well as individual patients wishes.

Chordomas are rare primary bone tumors that arise from the axial skeleton. Our objective was to analyze trends in radiation and surgery over time and determine location-based survival predictors for chordomas of the skull base, mobile spine, and sacrum. A retrospective cohort study of the SEER (Surveillance Epidemiology and End Results) database from 1973 to 2013 was conducted. All patients had histologically confirmed chordomas. The principal outcome measure was overall survival (OS). The cohort included 1616 patients: skull base (664), mobile spine (444), and sacrum (508). Skull base tumors presented earliest in life (47.4 years) and sacral tumors presented latest (62.7 years). Rates of radiation remained stable for skull base and mobile spine tumors but declined for sacral tumors (P = 0.006). Rates of surgical resection remained stable for skull base and sacral tumors but declined for mobile spine tumors (P = 0.046). Skull base chordomas had the longest median survival (162 months) compared with mobile spine (94 months) and sacral tumors (87 months). Being married was independently associated with improved OS for skull base tumors (hazard ratio, 0.73; 95% confidence interval, 0.53-0.99; P = 0.044). Surgical resection was independently associated with improved OS for sacral chordomas (hazard ratio, 0.48; 95% confidence interval, 0.34-0.69; P mobile spine chordomas and radiation for sacral chordomas decreased over time. Patients with skull base tumors survived longer than did patients with mobile spine and sacral chordomas, and surgical resection was associated with improved survival in sacral chordomas only. Understanding the behavior of these tumors can help cranial and spinal surgeons improve treatment in this patient population. Copyright © 2018 Elsevier Inc. All rights reserved.

2004-10-01

Genital herpes (GH) causes genital ulcer disease, severe transient pain, and often paresthesias. Whether or not GH can cause urinary retention or chronic neuropathic pain is not well known. We present two immunocompetent patients with GH associated with neuropathic symptoms. We also review the literature on GH and associated neurologic problems. Patient 1 had primary herpes simplex virus (HSV)-2 infection with transient urinary retention and chronic bilateral neuropathic pain in the sacral area. Patient 2 had recurrent HSV-1 associated with unitaleral chronic neuropathic pain in the sacral area. Although transient urinary retention associated with GH is not uncommon, chronic neuropathic pain has not been reported previously. Our cases show that chronic neuropathic pain, that is "pain initiated or caused by a primary lesion or dysfunction in the nervous system," can follow genital HSV infection.

Surgical site infections (SSIs) are a concern in pediatric spine surgery with unusually high rates for a clean surgery and especially for patients with deformity of nonidiopathic etiology. Microbiologic differences between etiologies of spine deformities have been poorly investigated. We reviewed all cases of SSI in spinal surgery between 2007 and 2011. Characteristics of cases and of bacteria according to the etiology of the spine disease were investigated. Of 496 surgeries, we identified 51 SSIs (10.3%) in 49 patients. Staphylococcus aureus was the most frequent pathogen whatever the etiology (n = 31, 61% of infection cases). The second most frequent pathogens vary according to the etiology of the spine deformity. It was Gram-negative bacilli (GNB) in nonidiopathic cases (n = 19, 45% of cases) and anaerobe in idiopathic cases (n = 8, 38% of cases), particularly Gram-positive anaerobic cocci (n = 5, 24% of cases). Infection rate was 6.8% in cases with idiopathic spine disease (n = 21) and 15.9% in cases with nonidiopathic spine disease (n = 30). Nonidiopathic cases were more frequently male with lower weight. American Society of Anesthesiologists score was more often greater than 2, they had more frequently sacral implants and postoperative intensive care unit stay. GNB were significantly associated with a nonidiopathic etiology, low weight, younger age and sacral fusion. SSIs were polymicrobial in 31% of cases with a mean of 1.4 species per infection cases. S. aureus is the first cause of SSI in pediatric spine surgery. However, Gram-positive anaerobic cocci should be taken into account in idiopathic patients and GNB in nonidiopathic patients when considering antibiotic prophylaxis and curative treatment.

Chronic idiopathic anal pain (CIAP) remains a diagnosis of exclusion. Its study and management still lack a standardized protocol. The aim of this study is to evaluate the results obtained with the diagnostic-therapeutic protocol established in our service. We performed a retrospective study of patients diagnosed with CIAP at the Colorectal Unit of the General University Hospital of Elche, between 2005 and 2011. We evaluated 57 patients with a diagnosis of chronic anal pain for functional anorectal disease (FAD). After the application of our diagnostic protocol, final diagnosis of chronic anal pain (CAP) was achieved in 43 cases (75%), including 22 cases of descending perineum syndrome, 12 of proctalgia fugax, 2 of pudendal neuritis and 7 of coccydynia. In 14 patients exclusion diagnosis of CIAP was established. Among the therapies used on patients with CIAP, biofeedback combined with conservative measures improved symptoms in 43% of the cases. Sacral nerve stimulation was assessed in patients who did not respond to other treatments. Through proper anamnesis, physical examination and complementary tests, a specific diagnosis of the cause of CAP by FAD can be achieved, reducing exclusion diagnosis of CIAP to 25% of cases. Conservative measures combined with biofeedback achieved an improvement in pain in more than 40% of the cases of CIAP in our study. Sacral nerve stimulation can be considered as a treatment option in refractory cases. Copyright © 2013 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

To assess the relative cost-effectiveness of two therapeutic strategies: one starting with sacral neuromodulation (SNM) versus one starting with Botulinum toxin A (BTX-A) for the management of refractory incontinent idiopathic overactive bladder (OAB) patients, from the perspective of the Italian National Health Service (INHS). Direct medical costs (2011) and benefits (quality-adjusted life years-QALYs) were assessed over a ten-year time frame adapting to the Italian practice a published Markov model. Clinical inputs were based on the published literature and on the expert opinion. Resource consumption rates were provided by clinical experts; unit costs were collected from a single hospital accounting and from standard tariff lists and public prices. Interventional procedures and management of adverse events were costed through a micro-costing approach. The primary outcome was incremental costs per QALYs gained (i.e. differential costs divided by differential benefits). Deterministic (DSA) and probabilistic (PSA) sensitivity analyses were conducted to assess the robustness of the model. Starting with SNM appears to be cost effective (i.e. under 40.000/QALY) from year three (21,259/QALY) onwards and becomes dominant (i.e. more effective and less costly) at year ten: cumulative costs were 32,975 for early SNM and 33,309 for early BTX-A, while cumulative QALYs were 7.52 and 6.93, respectively. At year ten, DSA suggests the results robustness and 99.8 % of the PSA iterations fell within the cost-effectiveness threshold. A therapeutic strategy starting with SNM may be considered cost effective in the midterm and cost saving in the long-term treatment of idiopathic OAB from the INHS perspective.

Goal of the study This study intends to develop a method of quantitative sagittal balance parameters assessment, based on a geometrical model of lumbar spine and sacrum. Methods One hundred eight patients were divided into 2 groups. In the experimental group have been included 59 patients with lumbar spinal stenosis on L1-5 level. Forty-nine healthy volunteers without history of any lumbar spine pathlogy were included in the control group. All patients have been examined with supine MRI. Lumbar lordosis has been adopted as circular arc and described either anatomical (lumbar lordosis angle), or geometrical (chord length, circle segment height, the central angle, circle radius) parameters. Moreover, 2 sacral parameters have been assessed for all patients: sacral slope and sacral deviation angle. Both parameters characterize sacrum disposition in horizontal and vertical axis respectively. Results Significant correlation was observed between anatomical and geometrical lumbo-sacral parameters. Significant differences between stenosis group and control group were observed in the value of the “central angle” and “sacral deviation” parameters. We propose additional parameters: lumbar coefficient, as ratio of the lordosis angle to the segmental angle (Kl); sacral coefficient, as ratio of the sacral tilt (ST) to the sacral deviation (SD) angle (Ks); and assessment modulus of the mathematical difference between sacral and lumbar coefficients has been used for determining lumbosacral balance (LSB). Statistically significant differences between main and control group have been obtained for all described coefficients (p = 0.006, p = 0.0001, p = 0.0001, accordingly). Median of LSB value of was 0.18 and 0.34 for stenosis and control groups, accordingly. Conclusion Based on these results we believe that that spinal stenosis is associated with an acquired deformity that is measureable by the described parameters. It's possible that spinal stenosis occurs in patients with an

Opacification of collateral pathways other than the central channels is very rare in lumbar epidural venography. Two cases of opacification of the inferior mesenteric vein following extravasation of contrast medium at the tip of the lateral sacral vein catheter are reported. One case is presented in which filling of normal parametrial venous plexuses and the left ovarian vein occurred as a consequence of incompetent or absent valves in the internal iliac vein. The literature containing comparable collateral flow patterns in disease is reviewed. The significance of the phlebographic features in our cases is discussed. (orig.)

To compare accuracy and consistency of sacral screw placement in canine pelves treated for sacroiliac luxation with open reduction and internal fixation (ORIF) or minimally invasive osteosynthesis (MIO) techniques. Unilateral sacroiliac luxations created experimentally in canine cadavers were stabilized with an iliosacral lag screw applied via ORIF or MIO techniques (n = 10/group). Dorsoventral and craniocaudal screw angles were measured using computed tomography multiplanar reconstructions in transverse and dorsal planes, respectively. Ratios between pilot hole length and sacral width (PL/SW-R) were obtained. Data between groups were compared statistically (p sacroiliac luxations provides more accurate and consistent sacral screw placement than ORIF. With proper techniques, iatrogenic neurological damage can be avoided with both techniques. The PL /SW-R, which relates to safe screw fixation, also demonstrates that screw penetration of at least 60% of the sacral width is achievable regardless of surgical approach. These findings, along with the limited dissection needed for accurate sacral screw placement, suggest that MIO of sacroiliac luxations is a valid alternative to ORIF.

Tani, Ichiro (St. Marianna Univ., Kawasaki (Japan). School of Medicine)

1993-12-01

The author reviewed 71 consecutive cases of acute trauma of the cervical spine to define efficacies of various modalities such as plain film, CT and MRI. Pathologies on CT and/or MRI additionally found to plain films were analyzed and correlated to three groups divided according to neurological deficit. The following conclusions were obtained. The usefulness of plain films as the first modality of choice was confirmed. Both CT and MRI are necessary in addition to abnormal plain films in this group if patients have neurological deficit. MRI may be a modality of choice following plain films if they are negative. In the group of brachial plexus palsy MRI should be performed before CT to demonstrate traumatic meningocele. CT myelography is also useful although it is invasive. It is warranted to say that in the asymptomatic group CT and MRI are not indicated, because additionally found abnormalities are clinically insignificant. (author).

Full Text Available Abstract Background Leptomeningeal carcinomatosis occurs in patients with cancer at the rate of approximately 5%; it develops particularly in patients with breast cancer, lung cancer, melanoma, leukemia, or malignant lymphoma. We describe a rare case of leptomeningeal carcinomatosis in which spinal intradural squamous cell carcinoma with no lesions in the cerebral meninges and leptomeninx, was the primary lesion. Methods A 64-year-old man complained of sacral pain. Although the patient was treated with analgesics, epidural block and nerve root block, sacral pain persisted. Since acute urinary retention occurred, he was operated on. The patient was diagnosed as having an intradural squamous cell carcinoma of unknown origin. Results Since the patient presented with a slightly decreased level of consciousness 2 months after surgery, he was subjected to MRI scanning of the brain and spinal cord, which revealed disseminated lesions in the medulla oblongata. The patient died of pneumonia and sepsis caused by methicillin-resistant Staphylococcus aureus 5 months after surgery. Conclusion We report the first case of a patient with intradural squamous cell carcinoma with unknown origin that developed independently in the sacrum.

Extra-skeletal Ewing sarcoma in pregnancy is rare. There is thus limited scientific evidence to guide clinicians in its complicated management, particularly within the context of early gestation. We therefore share our successful outcome in a 32-year-old pregnant patient, following a unique management strategy of complete aggressive surgical resection prior to neo-adjuvant therapy. The case involved a 2-month history of right-sided back and gluteal pain, with associated paraesthesia. Lumbosacral magnetic resonance imaging (MRI) revealed an approximate 40×50 mm indeterminate mass in the lower right paraspinal musculature. The mass extended into the first right sacral foramen and the central canal; and also impinged on the S2 exiting nerve. After considering the patients' rapid deterioration, pregnant status and other clinical factors, it was elected to proceed with complete surgical resection prior to any other therapeutic modality. Following surgery, the patient experienced immediate resolution of her pain and by 6 weeks was able to cease the use of all analgesics. At 32-weeks' gestation she underwent an uncomplicated vaginal delivery. At 9 months follow up, she remains disease free and has experienced complete resolution of her back pain and radiculopathy.

Sacroiliac (SI) joint dysfunction is a common source of chronic low-back pain. Recent evidences from different parts of the world suggest that cooled radiofrequency (RF) neuroablation of sacral nerves supplying SI joints has superior pain alleviating properties than available existing treatment options for SI joint dysfunctional pain. A 35-year-old male had intractable bilateral SI joint pain (numeric rating scale [NRS] - 9/10) with poor treatment response to intra-articular steroid therapy. Bilateral water cooled = RF was applied for neuroablation of nerves supplying both SI joints. Postprocedure pain intensity was 5/10 and after 7 days it was 2/10. On 18 th -month follow-up, he is pain free except for mild pain (NRS 2/10) on occasional extreme twisting of the back. This case attempts to highlight that sacral neuroablation based on cooled RF technique can be a long lasting remedial option for chronic SI joint pain unresponsive to conventional treatment.

Castleman disease (CD) is a rare benign disorder characterised by hyperplasia of lymphoid tissue that may develop at a single site or throughout the body. The etiology of this disorder is unclear, although the histopathological presentation can be differentiated into a hyaline vascular variant, a plasma cell variant and a mixed variant. Clinically, it has been recorded that 3 manifestations of CD are characterized: a localized unicentric type, a generalized multicentric type and a mixed form. Surgery remains the main treatment for resectable unicentric CD, since removal of the large node is possible without further complications. No consensus has been reached concerning the most adequate treatment for irresectable unicentric CD. Case report of a 67 year old woman. This report, describes the case of a 67-year-old woman with unicentric Castleman disease located in the right lower abdomen. The patient had symptoms of fatigue, dyspnoea and pain in the right lower abdomen. Computed tomography (CT)- examination revealed a tumour, which had grown to form a close relationship with the common iliac vessels and the sacral bone. A Laparotomy procedure revealed that the tumour was an irresectable mass. Neo-adjuvant radiotherapy (40 Gy) was administered in order to downsize the tumour. Six weeks later a new CT-scan revealed a major reduction of the tumour, which enabled a successful radical resection of the tumour to be performed. Histopathological analysis of the tumour showed the hyaline vascular type of CD. Neo-adjuvant radiotherapy should be considered in case of an irresectable unicentric CD

Sacral neuromodulation (SNM) may improve interstitial cystitis/painful bladder syndrome (IC/BPS) symptoms of urinary frequency, urgency and perhaps even pain, but objective measures of improvement are lacking. We evaluated the potential for urinary chemokines to serve as measures of treatment response over time to SNM. Women with IC/BPS undergoing SNM consented for this study. Three-day bladder/pain diaries were collected at baseline and validated Interstitial Cystitis Symptom Problem Index (ICSPI) scores and mid-stream urine specimens were collected at baseline and at 24 weeks after successful implant. Collected urine was screened for infection by dipstick and analyzed for chemokines by luminex xMAP analysis. At baseline (n = 16), urine levels of CXCL-1 positively correlated with pain score (r = 0.63, P = 0.009), urgency (r = 0.61, P = 0.01), ICSPI (r = 0.43, P = 0.09) and daily voids (r = 0.44, P = 0.08). ICSPI and pain scores also positively correlated with sIL-1ra (r = 0.50, P = 0.04) and monocyte chemotactic protein-1 (MCP-1) or CCL2 positively correlated with daily voids (r = 0.45, P = 0.07) only. At 24 weeks, the median ICSPI index fell from 28 to 15 (n = 7, P = 0.008). Urine levels of sIL-1ra (633.8 ± 188.2 vs. 149.9 ± 41.62 pg/mL) and MCP-1 (448.3 ± 11.6 vs. 176.9 ± 46.16 pg/mL) and CCL5 (20.78 ± 4.09 vs. 11.21 ± 4.12 pg/mL) were also significantly reduced at the follow-up relative to baseline values (P = 0.04). Multivariable analysis of data revealed that sIL-1ra and MCP-1 together explained the majority of variance in data. Levels of CXCL-1, CXCL-10, interleukin (IL)-8, vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF) were also reduced at 24 weeks, but differences were not significant. Concomitant decrease in urine levels of chemokines especially MCP-1 was associated with treatment response of SNM. These results

Full Text Available Local flaps exhibit excellent color matching that no other type of flap can compete with. Moreover, surgery using a local flap is easier and faster than surgery using a distant or free flap. However, local flaps can be much more difficult to design. We designed 2 templates to plan a V-Y rotation advancement flap. The template for a unilateral V-Y rotation advancement flap was used on the face (n=5, anterior tibia (n=1, posterior axilla (n=1, ischium (n=1, and trochanter (n=2. The template for a bilateral flap was used on the sacrum (n=8, arm (n=1, and anterior tibia (n=1. The causes of the defects were meningocele (n=3, a decubitus ulcer (n=5, pilonidal sinus (n=3, and skin tumor excision (n=10. The meningocele patients were younger than 8 days. The mean age of the adult patients was 50.4 years (range, 19–80 years. All the donor areas of the flaps were closed primarily. None of the patients experienced wound dehiscence or partial/total flap necrosis. The templates guided surgeons regarding the length and the placement of the incision for a V-Y rotation advancement flap according to the size of the wound. In addition, they could be used for the training of residents.

Full Text Available Terminal myelocystocele (TMC results from failure of embryonic CSF to drain outside the neural tube creating CSF reservoir within a dorsal meningocele. Association of Chiari II malformation with diastematomyelia and myelocystocele is extremely rare. Myelocystoceles do not have neural tissue so they have good prognosis after treatment, however when associated with hydromelia and Chiari malformation they present with neurological deficits. We present details of a 2 year old female who presented to us with this rare anomaly.

Objective: To evaluate criteria to differentiate sacral chordoma (SC), sacral giant cell tumor (SGCT) and giant sacral schwannoma (GSS) with CT and MRI. Materials and methods: CT and MR images of 22 SCs, 19 SGCTs and 8 GSSs were reviewed. The clinical and imaging features of each tumor were analyzed. Results: The mean ages of SC, SGCT and GSS were 55.1 ± 10.7, 34.3 ± 10.7 and 42.4 ± 15.7 years old. SCs (77.3%) were predominantly located in the midline of lower sacrum, while most SGCTs (73.7%) and GSSs (87.5%) were eccentrically located in upper sacrum. There were significant differences in age, location, eccentricity, morphology of bone residues, intratumoral bleeding and septations. Multiple small cysts were mainly observed in SGCTs (73.7%) with large central cysts in GSSs (87.5%). SGCTs expanded mainly inside sacrum while SCs and GSSs often extended into pelvic cavity (P = 0.0022). Involvement of sacroiliac joints and muscles were also different. Ascending extension within sacral canal was only displayed in SCs. The preservation of intervertebral discs showed difference between large and small tumors (P = 0.0002), regardless of tumor type (P = 0.095). No significant difference was displayed in gender (P = 0.234) or tumor size (P = 0.0832) among three groups. Conclusion: Age, epicenter of the lesion (midline vs. eccentric and upper vs. lower sacral vertebra), bone residues, cysts, bleeding, septation, expanding pattern, muscles and sacroiliac joint involvement can be criteria for diagnosis. Fluid–fluid level is specific for SGCTs and ascending extension within the sacral canal for SCs. The preservation of intervertebral discs is related to tumor size rather than tumor type.

2015-11-01

Herpes zoster (HZ), a common vesiculo-erythematous skin disease associated with reactivation of varicella zoster virus in the cranial nerve, dorsal root, and autonomic ganglia, is accompanied by several related symptoms represented by postherpetic neuralgia. Among them, involvement of vesicorectal dysfunction is relatively rare. The vesicorectal symptom can usually be recovered in transient course, but is quite important in terms of impaired quality of life. Male individuals affected with HZ and skin lesions on sacral dermatome have been reported as independent risk factors of zoster-related voiding dysfunction. In this study, urinary symptoms were focused upon and six patients with zoster-related voiding dysfunction at a single faculty of dermatology in Japan from 2009 to 2014 were retrospectively analyzed. All patients showed HZ lesions on the sacral area and the urinary symptom recovered in approximately 2 months (14 days to 7 months). The term of treatment for zoster-associated urinary dysfunction was positively correlated with that for zoster-related pain without significance (r = 0.661, P = 0.153). Average treatment term for pain relief of sacral HZ accompanied by voiding dysfunction (91.3 ± 76.44 days) was significantly longer than that of sacral HZ without urinary symptom (18.9 ± 20.42 days) (P = 0.032). These results suggested that zoster-related voiding dysfunction would mainly be involved in sacral HZ and closely associated with severity of zoster-related pain. Dermatologists should be aware that severe zoster-related pain accompanied by sacral HZ, which is related to prolonged treatment of pain relief, can be a predictive factor of voiding dysfunction. © 2015 Japanese Dermatological Association.

The aim of this study is to assess the long-term clinical and radiological outcomes between minimally invasive (MIS) and conventional transforaminal lumbar interbody fusion (TLIF) in treating one-segment lumbar disc herniation (LDH). One-hundred and six patients treated by MIS-TLIF (50 cases) or conventional TLIF (56 cases) were included. Perioperative results were evaluated. Clinical outcomes were compared preoperatively and postoperatively. Radiologic parameters were based on a comparison of preoperative and three-year postoperative lumbar lordosis, segmental lordosis, sacral slope, the cross-sectional area of the paraspinal muscle and fusion rates. MIS TILF had significantly less blood, shorter operation time, mean return to work time and lower intramuscular pressure compared with the conventional group during the operation. VAS scores for lower back pain and ODI in MIS-TLIF were significantly decreased. The mean cross-sectional area of the paraspinal muscle was significantly decreased after surgery in the conventional TLIF group and no significant intragroup differences were established in the MIS-TLIF group. No significant differences were found in fusion rate, lumbar lordosis, segmental lordosis and sacral slope. Both MIS and conventional TLIF were beneficial for patients with LDH. However, MIS-TLIF manifests a great improvement in perioperative outcomes, low back pain, disability and preventing paraspinal muscle atrophy during the follow-up period observation.

Objectives This study aimed to define a safe corridor for 2.7 mm cortical sacroiliac screw insertion in the dorsal plane (craniocaudal direction) using radiography and CT, and in the transverse plane (dorsoventral direction) using CT in feline cadavers. A further aim was to compare the values obtained by CT with those previously reported by radiography in the transverse plane. Methods Thirteen pelvises were retrieved from feline cadavers and dissected to expose one of the articular surfaces of the sacrum. A 2.7 mm screw was placed in the sacrum to a depth of approximately 1 cm in each exposed articular surface. Dorsoventral radiography and CT scanning of each specimen were performed. Multiplanar reconstructions were performed to allow CT evaluation in both the dorsal and transverse planes. Calculations were made to find the maximum, minimum and optimum angles for screw placement in craniocaudal (radiography and CT) and dorsoventral (CT) directions when using a 2.7 mm cortical screw. Results Radiographic measurement showed a mean optimum craniocaudal angle of 106° (range 97-112°). The mean minimum angle was 95° (range 87-107°), whereas the mean maximum angle was 117° (108-124°). Measurement of the dorsal CT scan images showed a mean optimum craniocaudal angle of 101° (range 94-110°). The mean minimum angle was 90° (range 83-99°), whereas the mean maximum angle was 113° (104-125°). The transverse CT scan images showed a mean dorsoventral minimum angle of 103° (range 95-113°), mean maximum angle of 115° (104-125°) and mean optimum dorsoventral angle of 111° (102-119°). Conclusions and relevance An optimum craniocaudal angle of 101° is recommended for 2.7 mm cortical screw placement in the feline sacral body, with a safety margin between 99° and 104°. No single angle can be recommended in the dorsoventral direction and therefore preoperative measuring on individual cats using CT images is recommended to establish the ideal individual angle in the

CEI rarely leads to neurologic complications. We report a case of persistent cauda equina syndrome after CEI. A 44-year-old male patient with severe L4 and L5 spinal stenosis underwent CEI for low-back pain and sciatica. The CEI solution consisted of bupivacaine, hyaluronidase, triamcinolone acetonide, and normal saline. He experienced motor weakness and sensory loss in both lower extremities and neurogenic bladder for more than 1 year after the procedure. His ankle dorsiflexors, big-toe extensors, and ankle plantar flexors on both sides were checked and categorized as motor-power Medical Research Council grade 0. His bilateral ankle-jerk reflection was absent. An electrophysiological study showed lumbosacral polyradiculopathy affecting both sides of the L5 and S1 nerve roots. A urodynamic study revealed hypoactive neurogenic bladder affecting both sacral roots. Keywords: epidural injection, cauda equina syndrome, complications

Three patients with genital herpes simplex type II primoinfection and acute urinary retention are described. All patients showed pleocytosis of the cerebrospinal fluid, substantiating central nervous involvement. The association of genital herpes and sacral (myelo-) radiculitis has gained little attention in gynecologic literature, yet it is not an uncommon finding in female patients suffering from herpes. The present report emphasizes the importance of urinary symptoms in genital herpes and reviews the literature on similar cases.

Sagittal decompensation after pedicle subtraction osteotomy (PSO) is considered as late onset complication. Several mechanisms have been suggested, but little attention has been paid to the caudal end of lumbar instrumented fusion, especially sacral iliac joint (SIJ) deterioration. Clinical histories and radiographic sagittal parameters of two patients with SIJ luxation after PSO are presented. The biomechanical failure mechanism and risk factors are analysed. Two patients underwent correction of fixed anterior sagittal imbalance by PSO, followed by pseudarthrosis revision surgery. Both of them sustained persistent sacroiliac pain, progressive recurrence of anterior imbalance and progressive pelvic incidence (PI) increase around 10°. An acute bilateral SIJ luxation occurred in both patients leading to sharp increase or PI around 20°. One patient was treated by SIJ fusion and the other patient was placed on non-weight-bearing crutch ambulation for 1 year. Both patients had a high preoperative PI (95° and 78°). A theoretical match between lumbar lordosis (LL) and PI was not achieved by PSO. Osteopenia was present in both patients. Computed tomography evidenced L5-S1 pseudarthrosis and sacroiliac joint violation by pelvic or sacral ala screws. Patients with high PI might seek for further compensation at their SIJ when lacking LL after PSO. Chronic anterior imbalance might lead to progressive weakening of sacroiliac ligaments. Initial circumferential lumbosacral fusion and accurate iliac screw fixation might reduce stress on implants, risk for pseudarthrosis, implant failure and finally SIJ deterioration. Bone mineral density should further be investigated preoperatively.

1982-01-01

Lipiodol Ultra-Fluide (0.2 ml/kg) was injected directly into the lymphatic vessels of the pelvic limbs in 28 healthy adult mongrel dogs. The contrast medium appeared on the roentgenogram in the popliteal, lateral iliac, medial iliac, sacral and lumbar aortic lymph nodes (LN). It was also visible in the iliofemoral, superficial inguinal and cranial mediastinal LN in several dogs. It diffused from the popliteal into the sacral, medial iliac and lateral iliac LN to fill the cisterna chyli and thoracic duct system. The features of the popliteal, lateral iliac and lumbar aortic LN were shown in the lymphangiograms of all the animals. The incidence of the other LN was different. Depending on the incidence of these LN in the lymphangiogram, the pictures of the canine lymphatic system were classified into three types:(1) medial iliac and sacral LN were visible on both sides (16%);(2) one of these LN was not observed (36%);(3) medial iliac and/or sacral lymph node was not observed on both sides (48%).

Full Text Available Objectives: To investigated the rate of occurrence of lumbosacral transitional vertebrae (LSTV, spinal variant, in kidney urinary bladder (KUB plain radiographs in a Saudi population. Methods: Between January 2012 to January 2015, KUB plain films obtained from patients at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, were reviewed, and the presence or absence of LSTV was documented and classified as incomplete or complete. Patients who had evidence of spinal surgery that would obscure the view were excluded. Results: A total of 2078 patients underwent KUB examinations during the study period; LSTV anomalies were detected in 158 of these. Sacralization was present in 153 (96.8% of this cohort, while lumbarization was present in 5 (3.2%. A total of 136 (86.1% of the sacralized segments were of the incomplete type, whereas 17 (10.7% were complete. Of the lumbarized vertebrae, 3 (1.8% were incomplete, and 2 (1.2% were complete. The most frequent type in men was type Ib (28.5% for sacralized segments, and type IIb for lumbarized segments (0.6%. In women, type Ia was the most common form of sacralized segments (11.3% and type IIb was the most common form of lumbarized segments (2.8%. Conclusion: The prevalence of LSTV in Saudi patients is 7.6%, with a higher incidence of sacralization than lumbarization. Further studies with larger sample sizes and longer follow-up time are needed to demonstrate the clinical significance thereof.

Herpes simplex virus type 1 (HSV-1) is isolated principally from the upper half of the body innervated by the trigeminal ganglia whereas herpes simplex virus type 2 (HSV-2) is generally isolated from the lower half of the body innervated by the sacral ganglia. However, recent reports suggest that HSV-1 and HSV-2 can each infect both the upper and lower half of the body causing a variety of symptoms and there is a possibility that HSV-1 and HSV-2 infections can occur simultaneously with both causing symptoms. HSV type in clinical isolates from 87 patients with genital herpes and 57 with ocular herpes was determined by the polymerase chain reaction (PCR), and six cases of mixed infection with both HSV-1 and HSV-2 were identified. Of the six cases, three were patients with genital herpes and three were ocular herpes patients. Analysis of the copy number of the HSV-1 and HSV-2 genome by a quantitative real time PCR demonstrated that HSV-1 was dominant at a ratio of approximately 100:1 in the ocular infections. In contrast, the HSV-2 genome was present at a 4-40 times higher frequency in isolates from genital herpes patients. There was no obvious difference between the clinical course of mixed infection and those of single HSV-1 or HSV-2 infections. This study indicated that the frequency of mixed infection with both HSV-1 and HSV-2 is comparatively higher than those of previous reports. The genome ratio of HSV-1 and HSV-2 reflects the preference of each HSV type for the target organ.

Herpes zoster (shingles) is caused when the varicella zoster virus that has remained latent since an earlier varicella infection (chicken-pox) is reactivated. Herpes Zoster is a less common and endemic disease than varicella: factors causing reactivation are still not well known, but it occurs in older and/or immunocompromised individuals. Following reactivation, centrifugal migration of herpes zoster virus (HZV) occurs along sensory nerves to produce a characteristic painful cutaneous or mucocutaneous vesicular eruption that is generally limited to the single affected dermatome. Herpes zoster may affect any sensory ganglia and its cutaneous nerve: the most common sites affected are thoracic dermatomes (56%), followed by cranial nerves (13%) and lumbar (13%), cervical (11%) and sacral nerves (4%). Among cranial nerves, the trigeminal and facial nerves are the most affected due to reactivation of HZV latent in gasserian and geniculated ganglia. The 1st division of the trigeminal nerve is commonly affected, whereas the 2nd and the 3rd are rarely involved. During the prodromal stage, the only presenting symptom may be odontalgia, which may prove to be a diagnostic challenge for the dentist, since many diseases can cause orofacial pain, and the diagnosis must be established before final treatment. A literature review of herpes zoster of the trigeminal nerve is presented and the clinical presentation, differential diagnosis and treatment modalities are underlined. A case report is presented.

Full Text Available Background: Asthma is an inflammatory clutter of the airways that causes wheezing, breathlessness, chest tightness, and coughing. In India, approximate calculation indicates a prevalence of between 10% and 15% in 5-11 year old children. Modern Western treatment focuses on controlling asthma with two classes of medication corticosteroids and bronchodilatorss. Another plan of action for reducing and potentially even throw out asthma manifestation affects manipulation of the craniosacral fascial system. This system is a unification of the craniosacral and fascial or connective tissue part. This idea can help in making clear the greatly high rate of achievement with manual therapy in pediatric asthma. Methods: In this case report first I have taken a brief history of the patient condition after the full assessment like brain cycle rhythm, chest and systemic. I have given cranio sacral therapy, Intercostal release, PNF for diaphragm release on child for seven sitting of about 45 minutes of each session. Results: After completion of treatment session of seven sitting his lungs to be bright of any wheezing or other impediment. Brain cycle was of 90 seconds. His peak flow meter readings were between 250 and 300 Liters/minute, which were in a satisfactory range for him. The physician suggested that at this point there was no requirement for any additional asthma medicines. Conclusion: It comes into sight that the loss to the respiratory system caused by fascial burden early in life may be fully reversible, if treated immediately. The latent grace of this interdependent approach is that it crop up to address the pathological origin of asthma.

Full Text Available Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. Case report: We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Conclusion: Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

Full Text Available Background: In children with cerebral palsy, primary (eg, abnormal muscle tone and weakness and secondary impairments (eg, contractures can modify pelvic-spinal alignment. The main aim of this article was to establish a new approach to pelvic-spinal analysis in children with cerebral palsy, taking into account the whole pelvis-spine complex, illustrated by a case study. Methods: This is a case study of an ambulatory child with cerebral palsy (spastic diplegia who underwent analysis of the pelvic-spine complex from X-ray images taken in standing position from C2 to the proximal femur. Pelvic shape was characterized by the pelvic incidence angle, which is the sum of sacral slope and pelvic tilt, before and after the treatment by regular onabotulinumtoxinA injections into the hip flexors, and the use of soft lumbar brace over 5 years. Results: The sagittal balance of the spine was improved following the treatment, with a reduction in lumbar lordosis and sacral slope. The reduction in lumbar hyperextension likely reduced the risk of spondylolysis, low back pain, and degenerative spondylolisthesis in adulthood. Conclusion: A biomechanical approach to the evaluation of the pelvic-spinal complex offers new perspectives to increase the understanding of spinal balance in children with cerebral palsy, providing more options for treatment, such as onabotulinumtoxinA.

A total of 168 patients with spinal tumors were evaluated with MRI. The study shows that MRI is a sensitive method for demonstration of spinal tumors. MRI also provides a possibility to separate different histological types of tumors based on their morphology and signal characteristics. Intramedullary tumors (25 cases): Ependymomas (6 cases) and astrocytomas (7 cases) were most common. Ependymomas have a more irregular signal pattern than astrocytomas. Astrocytomas are more common in the upper spine and are more often completely cystic. Contrast enhancement is important for separation of cyst, edema and solid tumor. Intradural extramedullary tumors (31 cases): Neuromas (14 cases) and meningeomas (11 cases) were most common. Neuromas always had markedly increased signal intensity on T2-weighted images. Meningeomas were only hyperintense occasionally. Neuromas were more inhomogeneous than meningeomas on T1-weighted images. Contrast enhancement is valuable for delineation of small tumors. Extradural tumors (91 cases): 76 patients had metastases, 7 primary spinal tumors and 8 multiple myelomas. T1-weighted images are almost always superior to other sequences because tumor invasion in the fatty bone marrow is seen as a low signal area in contrast to the high signal from the fat. Spinal lymphomas (14 cases): May be divided into vertebral, paraspinal and epidural tumors. Most cases have all locations. Spinal neurofibromatosis (7 cases): Most patients had multiple, often bilateral neurofibromas. One patient had a meningeomas on one spinal dysplasia with meningoceles. MRI is superior to other modalities for evaluation of the full extent of the disease. The coronal view is often valuable because of the arrangement of the tumors. In addition to providing diagnosis, MRI is of great value in treatment follow-up

The computer tomography is useful in evaluation of bony structures and adjacent soft tissues of the lumbar spine. Recently, the multiplanar reconstruction of lumbar spine of CT of significant value for the anatomical localization and for the myelographic and surgical correlation. We observed 177 cases of lumbar spine CT, who complains of spinal symptom, during the period from Dec. 1982 to Aug. 1984. The results were as follows: 1. The sex distribution of cases were 113 males and 44 females. The CT diagnosis showed 152 cases of herniated lumbar disc, 15 cases of degenerative disease, 5 cases of spine tbc., 3 cases of spine trauma and 2 cases of meningocele. 2. CT findings of herniated disc were as follows: focal protrusion of posterior disc margin and obliteration of anterior epidural fat in all cases, indentation on dural sac in 92 cases (60.5%) soft tissue mass in epidural fat in 85 cases (55.9%), compression or displacement of nerve root sheath in 22 cases(14.4%). 3. Sites of herniated lumbar disc were at L4-L5 level in 100 cases(59.1%) and at L5-S1 level in 65 cases (38.4%). Location of it were central type in 70 cases(41.1%), left-central type in 46 cases (27.2%), right-central type in 44 cases(26.0%) and lateral type in 9 cases (5.1%). 4. The sagittal reconstruction images were helpful in evaluating neural foramina, size of disc bluge into spinal canal, especially at L5-S1, and patients with spondylolisthesis. The coronal reconstruction images were the least informative, although they contributed to the evaluation of lumbar nerve roots of course, the axial CT scans were the most sensitive and specific.

The lumbosacral spine (L5–S3) was examined by high resolution computed tomography (CT) in five canine cadaver specimens and one anesthetized dog using 5mm thick transverse slices at 5mm intervals. In each dog, anatomic features observed on CT images were confirmed by comparison with corresponding 5 mm thick anatomic transverse sections and section radiographs. CT anatomic features visualized in all dogs included the vertebral bodies, pedicles, laminae, articular processes, spinous processes, transverse processes, mammillary processes, basivertebral venous canals, vertebral foramina, intervertebral foramina, sacral wings, median sacral crest, intermediate sacral crests, lateral sacral crests, articular process joints, sacroiliac joints, internal vertebral venous plexus, epidural fat, thecal sac, L5–S3 nerve roots, and spinal nerves. Spinal ganglia, yellow ligaments, and portions of the intervertebral discs were visible in some dogs. The spinal cord, intrathecal nerve roots, dorsal and ventral longitudinal ligaments, spinal arteries, and radicular vessels were not distinguishable. Accessory processes were identified on the caudal L5 pedicles in most dogs, an observation that differed from descriptions in standard anatomy texts. Previously undescribed osseous grooves, termed “lateral recesses,” were identified in the caudal L7 vertebral foramen of all dogs

To evaluate MR imaging of sacrococcygeal chordoma. Thirty patients (age range 22-80 years) underwent MR imaging for the diagnosis and preoperative evaluation of sacrococcygeal chordomas. Eight patients had follow-up MR examination after treatment. The MR images were performed with T1- and T2-weighted imaging, and gadolinium (Gd)-enhanced imaging. The MR images were analyzed for the signal intensity, enhancing pattern, tumor size, growth pattern of the soft tissue component, and tumor extension. T1-weighted images showed low signal masses with foci of high signal intensity in 73% of cases. Tumors enhanced in a variety of patterns after the administration of Gd. Soft tissue masses extending anteriorly were seen in all cases with posterior extension in 77% of cases. The posterior masses involved the surrounding muscles and extended toward the greater sciatic notch, appearing with pseudopodia (87%). Sacroiliac joints were involved in 23% of cases. Four lesions showed intraspinal extension and involvement of the posterior spinal muscles above the level of bony involvement. In 6 patients recurrent tumors were found at or around the surgical margin of the tumor 6 months to 5 years after resection of the sacral tumor. In two of the patients, nodular metastases to the pelvic bones and femur were found 1-4 years after initial examination. In conclusion, MR imaging is useful in the diagnosis and preoperative assessment of sacrococcygeal chordoma. Characteristic findings included sacral mass with heterogeneously high signal intensity with crisscrossing septa on long-repetition-time imaging, well-encapsulated pseudopodia-like or lobulated appearance, and gluteal muscle infiltration. Follow-up MR imaging is helpful to assess for recurrent or metastatic lesions of chordomas. (orig.)

The anteroposterior distances of S1, from the sacral promontory to the spinous process of S1 were 52.9± 5.2 mms and 50.4± 6.8 mms respectively for the male and female genders. The present study observed that the mean S1 pedicle length and the cephalocaudal height were higher (p<0.05 for the males than that of females. The data (male vs female were not found statistically different (p>0.05, with respect to the anteroposterior width of the S1 pedicle and the anteroposterior distances of S1 from the sacral promontory to the spinous process of S1. The present study has provided important morphometric data onto the pedicle of the first sacral vertebrae, from the anatomical samples of the South Indian population. The knowledge of pedicle diameters of S1 is crucial to the safe placement of screws in the posterior transpedicular screw fixation.

To observe the distribution and potential distribution patterns of osteolytic and sclerotic vertebral involvement in a representative collective of multiple myeloma patients. A total of 66 consecutive patients with a diagnosis of multiple myeloma at initial diagnosis or during follow-up were examined by multidetector reduced-dose computed tomography to evaluate the distribution of bone lesions along the spine with focus on size, location, and lesion character. Confirmation of diagnosis was performed by comparison to follow-up computed tomography or magnetic resonance tomography. If >50 % of all detected malignant lesions occurred in one spinal segment, the distribution pattern was called cervical, thoracic, lumbar, or sacral, otherwise a ''mixed'' pattern was classified. Of a total number of 933 osseous spine lesions, 632 (67.7 %) were classified as malignant (98.9 % of them osteolytic) and 293 (31.5 %) as benign. The distribution pattern analysis yielded two patients (3.8 %) with a cervical, 26 (50 %) with a thoracic, 4 (7.7 %) with a lumbar, one (1.9 %) with a sacral pattern, and 19 cases (36.6 %) showed a mixed distribution pattern. Segment-wise, the mean lesion size was 6.52 ± 2.76 mm (cervical), 8.97 ± 5.43 mm (thoracic), 11.97 ± 7.11 mm (lumbar), and 17.5 ± 16.465 (sacral), whilst, related to the vertebra size, the lesion/vertebra size ratio is decreasing through the whole spine beginning from the top. Multiple myeloma bone lesions occur preferably and are larger in the thoracic and lumbar spine. Moreover, a specific distribution pattern is present in about 60 %. (orig.)

To investigate the role of lumbosacral transitional vertebra (LSTV) in the pathogenesis of adolescent lumbar disc herniation (ALDH) and the association between LSTV type and the herniation level of ALDH. This study was a retrospective case-control analysis of roentgenographic images. All adolescent patients who received surgical treatment for L4/5 or L5/S1 single level lumbar disc herniation in our department from 2010 to 2015 were eligible for the ALDH group. All adolescent patients admitted to our hospital during the same period and who had ever undergone a plain anteroposterior radiologic examination of the abdomen and met the inclusion criteria that ensured the absence of any spinal disorders were selected into the control group. The anteroposterior lumbar or abdomen roentgenograms were collected to identify the LSTV. The incidence of LSTV in the ALDH group and the control group were compared. Among the ALDH group, the association between LSTV type (sacralization or lumbarization) and the herniation level of ALDH were evaluated. A total of 80 adolescent patients were included in the ALDH group and 92 asymptomatic adolescents were included in the control group. LSTV was found in 24 patients (30%) in ALDH group compared with 7 patients (7.6%) in the control group (P adolescent patients with sacralization, the L4/5 disc herniation was significantly more common than L5/S1 (81.3% vs. 18.7%; P = 0.019). The LSTV is associated with LDH in adolescents and the sacralization of L5 may contribute to the L4/5 disc herniation in adolescent patients. Copyright © 2017 Elsevier Inc. All rights reserved.

The effects of age, gender, and laterality on sacroiliac/sacral ratios obtained during quantitative joint imaging were assessed in 97 nonarthritic control subjects. For the entire group, the right sacroiliac-to-sacral mean ratio of 1.27 in 54 males was significantly higher than the right mean ratio of 1.18 in 53 females. In both genders the right joint ratio tended to be higher than the left in all age groups. The difference in mean ratio between the two joints was wider for males than for females. The age did not afect the joint ratio in either gender. It is concluded that the range of normal sacroiliac-to-sacral ratios are different for males and females and should be taken into account during a quantitative sacroiliac joint imaging examination

To describe the current indications, techniques and results of sacral root stimulation in patients with spinal cord lesions as a treatment for patients with high pressure bladders and/or urinary incontinence despite conservative management, as well as sacral root neuromodulation with permanent stimulators for complex bladder dysfunction: vesical instability, sensory urgency, chronic pelvic pain and chronic voiding dysfunction. The literature is reviewed, both techniques are described and the results of the most significant series are discussed, with special reference to the first groups that utilized these techniques. There is ample experience in the application of sacral root electrical stimulation. The reported results are comparable with those achieved by other treatments, such as augmentation cystoplasty. Neurostimulation and neuromodulation techniques are simple, the complications are minimal and they do not prelude the use of other therapies.

Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

Rothrock, J F; Walicke, P A; Swenson, M R

1986-11-01

Active infection with herpes zoster may cause acute urinary retention, especially when it involves sacral dermatomes. Although frank retention usually develops days to weeks after eruption of the typical rash, bladder incompetence infrequently develops first, raising concern over other, more ominous etiologies. In the case presented, rash appearance was delayed until six weeks after the initial onset of urinary retention, a much longer interval than previously reported. Occult herpes zoster infection should be considered in patients presenting with an acute neurogenic bladder of obscure cause.

Presacral venous haemorrhage during rectal movement is low, but is often massive, and even fatal. Our objective is the "in vitro" determination of the results of electrocoagulation applied to a fragment of muscle on the sacral bone surface during rectal resection due to a malignant neoplasm of the rectum. Single-pole coagulation was applied "in vitro" with the selector at maximum power on a 2×2 cms muscle fragment, applied to the anterior side of the IV sacral vertebra until reaching boiling point. The method was used on 6 patients with bleeding of the presacral venous plexus. In the "in vitro" study, boiling point was reached in 90 seconds from applying the single-pole current on the muscle fragment. Electrocoagulation was applied to a 2×2 cm rectal muscle fragment in 6 patients with presacral venous haemorrhage, using pressure on the surface of the presacral bone, with the stopping of the bleeding being achieved in all cases. The use of indirect electrocoagulation on a fragment of the rectus abdominis muscle is a straightforward and highly effective technique for controlling presacral venous haemorrhage.

The objective is to present the high-grade lumbosacral spondylolisthesis surgical experience. Spondylolisthesis causes chronic disabling pain, postural alteration and/or motor and sensory deficits in the lower extremities. Surgical stabilization is recommended in symptomatic adult and even in children or adolescents without symptoms because of the deformity progression potential. Stabilization can be done with or without reduction of the slippage; reduction implies neurological damage risk, bone (loosening) or implant (rupture) failure. Many authors recommended to do an in situ circumferential fusion arthrosis (inter body and inter transverse) associated with a transpedicular fixation in order to minimize the described risk. Eight patients were operated from 1993 to 2002. spondylolisthesis was analyzed according to clinical presentation, neurological dysfunction, postural alterations (slip angle, sacral inclination) complications and follow up. During follow up solid fusion was obtained with a better neurological function in all cases. One patient presented with a drop foot that reverted posteriorly; other patient had a superficial infection of the wound that was controlled. Slip angle improved between 8 - 42 and sacral inclination to 20 degrades. Present technique is recommended because it can be done a circumferential in situ arthrodesis in a single stage operation

Julia, Jimmy J; Cholhan, Hilary J

2007-01-01

An 87-year-old woman presents with a 4-week history of urinary incontinence during which she had been treated for disseminated herpes zoster virus (HZV). On physical exam painful vesicles involving the entire vulvar region with mainly right sacral distribution were found. A catheterized volume exceeded 600 ml of retained urine after the patient failed to void spontaneously. Multichannel voiding-pressure urodynamic studies revealed an acontractile neurogenic bladder with overflow incontinence. The patient was discharged on a conservative regimen with arrangement for visiting nurse services to perform intermittent self-catheterization twice daily. Urodynamic testing was repeated 10 weeks after initial symptoms. During voiding cystometry a biphasic increase in detrusor pressure of 15 cm H2O was observed with no increase in abdominal pressure. The patient emptied 400 ml with a postvoid residual of 300 ml. Recovery from HZV-associated bladder emptying dysfunction can be achieved usually through conservative management, including intermittent self-catheterization. Complete recovery time ranges from 4 to 10 weeks.

Rare presentation of acute urinary retention secondary to herpes zoster.

Science.gov (United States)

Ginsberg, P C; Harkaway, R C; Elisco, A J; Rosenthal, B D

1998-09-01

There are many causes of acute urinary retention. Reported here is a case of one of the more rare causes: herpes zoster. Fewer than 70 cases have been reported in the literature since 1890. In the present clinical environment where many patients are immunocompromised, reports of herpes zoster and its sequelae are no longer thought of as anecdotal. The virus may interrupt the detrusor reflex due to involvement of the sacral dorsal root ganglia. Urinary retention with sensory loss of both bladder and rectum as well as flaccid paralysis of the detrusor can develop in patients with herpes zoster. Fortunately, the outcome of this process is benign and full recovery of the detrusor is likely.

Because uncooked animal tissue is the primary source of Taenia, this indicated that the individual was likely consuming raw or undercooked meat of roe deer, red deer, or elk infected with Taenia. This finding represents the oldest case of a human infected with Taenia sp. from Eastern Siberia and Russia.

A rare case of low-grade primary leiomyosarcoma of the sacrum is described in a young woman who suffered from pain in the right sacroiliac region. A lytic sacral mass was observed on conventional radiology and CT studies. Magnetic resonance imaging clearly showed Gd-DTPA enhancement in the entire mass demonstrating its hypervascularity, which was later confirmed by angiography. Histopathology and immunohistochemical results of biopsy and curettage of the lesion confirmed the diagnosis. We report on the features of a rare tumor entity through imaging and diagnostic methods.

A syndrome involving acute urinary retention in combination with sacral radiculitis and cerebrospinal fluid pleocytosis was first described by the American neurosurgeon Charles Elsberg in 1931. In many instances the aetiology is herpes simplex virus type 2 (HSV-2) reactivation from sensory neurons. In this case report we present a 34-year-old pregnant woman with previous undiagnosed sensory lumbosacral symptoms. She was hospitalized with HSV-2 meningitis and lumbosacral radiculitis but no genital rash. A week after the onset of symptoms she developed acute urinary retention, thus indicating Elsberg syndrome.

This study aimed at evaluating the additional stability that is provided by anterior external and internal fixators in an unstable pelvic fracture model (OTA 61-C). An unstable pelvic fracture (OTA 61-C) was created in 27 synthetic pelves by making a 5-mm gap through the sacral foramina (posterior injury) and an ipsilateral pubic rami fracture (anterior injury). The posterior injury was fixed with either a single iliosacral (IS) screw, a single trans-iliac, trans-sacral (TS) screw, or two iliosacral screws (S1S2). Two anterior fixation techniques were utilized: external fixation (Ex-Fix) and supra-acetabular external fixation and internal fixation (In-Fix); supra-acetabular pedicle screws connected with a single subcutaneous spinal rod. The specimens were tested using a nondestructive single-leg stance model. Peak-to-peak (P2P) displacement and rotation and conditioning displacement (CD) were calculated. The Ex-Fix group failed in 83.3 % of specimens with concomitant single-level posterior fixation (Total: 15/18-7 of 9 IS fixation, 8 of 9 TS fixation), and 0 % (0/9) of specimens with concomitant two-level (S1S2) posterior fixation. All specimens with the In-Fix survived testing except for two specimens treated with In-Fix combined with IS fixation. Trans-sacral fixation had higher pubic rotation and greater sacral and pubic displacement than S1S2 (p < 0.05). Rotation of the pubis and sacrum was not different between In-Fix constructs combined with single-level IS and TS fixation. In this model of an unstable pelvic fracture (OTA 61-C), anterior fixation with an In-Fix was biomechanically superior to an anterior Ex-Fix in the setting of single-level posterior fixation. There was no biomechanical difference between the In-Fix and Ex-Fix when each was combined with two levels of posterior sacral fixation.

To develop an animal model to examine the pathophysiology by which S3 sacral root electrostimulation alters the micturition reflex in patients with bladder hyper-reflexia. Chronic sacral nerve root electrostimulation was applied to spinally transected rats; 21 animals were divided into four groups. The spinal cord was completely transected at the T10-11 level and stainless-steel electrodes implanted into the sacral foramen in 17 animals; these animals were subsequently divided into two groups (1 and 2). Six rats in group 1 underwent sacral root elctrostimulation for 2 h/day and five in group 2 for 6 h/day, for 21 days. The sham group (group 3, six rats) received no stimulation and four rats were used as healthy controls (group 4). Voiding frequency was recorded and each animal was evaluated cystometrically at the end of the stimulation period. The results were compared with the sham and control groups. Spinal cord transection resulted in bladder areflexia and complete urinary retention; 7-9 days after the injury, the bladder recovered its activity. Twenty-one days after transection all animals had evidence of uninhibited bladder contractions. The mean (SD) hourly frequency of urination was 0.66 (0.18) in healthy controls, 0.83 (0.21) in group 1, 0.87 (0.34) in group 2 and 1.1 (0.31) in group 3. There was a significant decrease in eh cystometric signs of bladder hyper-reflexia in groups 1 and 2 when compared with group 3. This work reports and initial study showing that chronic electrostimulation of sacral nerve roots can reduce the signs of bladder hyper-reflexia in the spinally injured rat. To our knowledge, this is the first report describing the rat as an animal model to determine the effects of chronic electrostimulation on the micturition reflex.

Full Text Available Objective:To associate spinopelvic parameters, pelvic incidence, sacral slope, pelvic tilt and lumbar lordosis with the axial location of lumbar disc herniation.Methods:Retrospective study, which evaluated imaging and medical records of 61 patients with lumbar disc herniation, who underwent surgery with decompression and instrumented lumbar fusion in only one level. Pelvic incidence, sacral slope, pelvic tilt and lumbar lordosis with simple lumbopelvic lateral radiographs, which included the lumbar spine, the sacrum and the proximal femur. The affected segment was identified as the level and location of lumbar disc herniation in the axial plane with MRI scans.Results:Of 61 patients, 29 (47.5% had low lumbar lordosis; in this group 24 (82.8% had central disc herniation, 4 (13.8% had lateral recess disc herniation and 1 (3.4% had extraforaminal disc herniation (p<0.05. Of the 61 patients, 18 (29.5% had low sacral slope; of this group 15 (83.3% had central disc herniation and 3 (16.7% had disc herniation in lateral recess (p<0.05.Conclusions:There is a trend towards greater load distribution in the anterior region of the spine when the spine has hypolordotic curve. This study found an association between low lordosis and central disc herniation, as well as low sacral slope and central disc herniation.

Full Text Available Objective 　To study the relationship between connexin 43 (Cx43 and N-methyl-D-aspartate (NMDA receptors and visceral sensitization in the rats with irritable bowel syndrome (IBS. Methods 　Thirty rats were gavaged with Triehinella spiralis to reproduce the IBS model. These rats were randomly divided into IBS group, IBS+colon distension group, and IBS+STI-571+colon distension group, and other groups of normal rats were randomized into normal group and normal+colon distension group, with 10 rats in each group. Immunofluorescent double staining were used to observe the expressions of intestine Cx43 and sacral NMDA re ceptors of rats in all the groups. Results 　The Cx43 and sacral NMDA expressions in the normal group, normal+colon distension group and IBS group showed no significant changes (P>0.05, however, Cx43 and sacral NMDA expressions were significantly higher in IBS rats with colon distension as compared with those in normal group, normal+colon distension group, and IBS group (P<0.05, while they were significantly lower in the IBS+STI-571+colon distension group after STI-571 intervention (P<0.05. Conclusion 　Cx43 and sacral NMDA may be the most important factor of visceral sensitization in IBS rats. DOI: 10.11855/j.issn.0577-7402.2015.12.02
