  2. Hip instability.

    Smith, Matthew V; Sekiya, Jon K

    2010-06-01

    Hip instability is becoming a more commonly recognized source of pain and disability in patients. Traumatic causes of hip instability are often clear. Appropriate treatment includes immediate reduction, early surgery for acetabular rim fractures greater than 25% or incarcerated fragments in the joint, and close follow-up to monitor for avascular necrosis. Late surgical intervention may be necessary for residual symptomatic hip instability. Atraumatic causes of hip instability include repetitive external rotation with axial loading, generalized ligamentous laxity, and collagen disorders like Ehlers-Danlos. Symptoms caused by atraumatic hip instability often have an insidious onset. Patients may have a wide array of hip symptoms while demonstrating only subtle findings suggestive of capsular laxity. Traction views of the affected hip can be helpful in diagnosing hip instability. Open and arthroscopic techniques can be used to treat capsular laxity. We describe an arthroscopic anterior hip capsular plication using a suture technique. PMID:20473129

    In newborns, US has an established role in the detection and management of developmental dysplasia of the hip. Later in childhood, when the limping child is a major diagnostic dilemma, US is extremely helpful in the identification of the varied disease processes underlying this condition, as transient synovitis, septic arthritis, Perthes disease and slipped femoral capital epiphysis. In adolescent practicing sporting activities, US is an excellent means to identify apophyseal injures about the pelvic ring, especially when avulsions are undisplaced and difficult-to-see radiographically. Later on, in the adulthood, US is an effective modality to diagnose tendon and muscle injuries about the hip and pelvis, identify effusion or synovitis within the hip joint or its adjacent bursae and guide the treatment of these findings. The aim of this article is to provide a comprehensive review of the most common pathologic conditions about the hip, in which the contribution of US is relevant for the diagnostic work-up.

    Full Text Available Hip arthroscopy is a safe method for treating a variety of pathological conditions that were unknown until a decade ago. Femoroacetabular impingement is the commonest of these pathological conditions and the one with the best results when treated early on. The instruments and surgical technique for hip arthroscopy continue to evolve. New indications for hip arthroscopy has been studied as the ligamentum teres injuries, capsular repair in instabilities, dissection of the sciatic nerve and repair of gluteal muscles tears (injuries to the hip rotator cuff, although still with debatable reproducibility. The complication rate is low, and ever-better results with fewer complications should be expected with the progression of the learning curve.

  10. 'Hip' pain.

    Zacher, Josef; Gursche, Angelika

    2003-02-01

    'Hip' pain is usually located in the groin, upper thigh or buttock and is a common complaint. Slipped capital femoral epiphysis, avascular femoral head necrosis and apophyseal avulsion are the most common diagnoses in childhood and adolescents. Strains and fractures are common in sport-active adults. Osteoarthritis occurs in middle-aged and older adults. Trauma may result in femoral head fracture or typical muscle and tendon sprains and bursitis. Septic or inflammatory arthritis can occur at every age. Septic arthritis, fractures and acute epiphyseal slipping are real emergency cases. Congenital dysplasia of the hip joint may lead to labral tears and early osteoarthritis. The most important hip problems in children, adolescents, adult and older people are discussed; these problems originate from intra-articular disorders and the surrounding extra-articular soft tissues. Medical history, clinical examination and additional tests, including imaging, will be demonstrated. Principles of treatment are given for specific disorders. PMID:12659822

  12. Hip dysplasia and congenital hip dislocation

    Lingg, G.; Nebel, G.; von Torklus, D.

    1981-11-01

    In human genetics and orthopedics quite different answers have been given to the question of hereditary transmission and frequency of hip dysplasia in families of children with congenital hip dislocation. We therefore have made roentgenometric measurements of 110 parents of children with congenital hip dislocation. In 25% we found abnormal flat acetabulae, whereas 12% had pathologic deep hips. This may propose a new concept of morphology of congenital hip dysplasia.

    Patients with problems following implantation of cemented total hip prostheses must be clinically examined. This examination is followed by a series of diagnostic imaging procedures. These include X-ray diagnosis, 3-phase 99mTc-MDP bone scans, scientigraphy for inflammation, and arthrography, performed singly or as sequential studies. X-ray findings and scientigraphic patterns arousing or confirming a suspicion of aseptic (mechanical) or septic (infectious) loosening of the prosthesis are evaluated and discussed. (orig.)

  4. Do normal hips dislocate?

    Alshameeri, Zeiad; Rehm, Andreas

    2014-11-01

    There have been a small number of case reports describing late normal-hip dislocations in children who were later diagnosed with developmental dysplasia of the hip. Here, we contest the assumption that normal hips can dislocate. We argue that (as in our case) the ultrasound scans in all published case reports on late dislocated normal hips did not show results that were entirely normal and therefore, so far, there has been no convincing evidence of a dislocation of a normal hip. We also want to highlight the importance of meticulous ultrasound and clinical assessments of high-risk children by an experienced orthopaedic surgeon. PMID:25144883

    Pain is the main reason inducing patients to undergo surgery and persistence of pain after the operation is a major concern, both for the patient and the surgeon. Up to 10% of patients report pain five years after hip arthroplasty. An analysis of the literature reveals numerous causes of pain localised to the replacement hip. In assessing a painful hip it is fundamental to arrive at a definite diagnosis before starting any treatment. Intrinsic causes can be identified, such as unrecognised as...

    2015-11-01

    Full Text Available In this thesis, our purpose is to show that using physiotherapy on patients with hip dysplasia from the very beginning, in the first months of life, helps treating them faster. Common literature proposes to use physiotherapy on patients with hip dysplasia either after their recovery or in the terminal phase of recovery, claiming that any earlier intervention will prolong the hip recovery. The effects of hip dysplasia reflect over the whole musculoskeletal system, while it hinders the knees (genu valgum, the ankles (ankle valgus, calcaneal valgus and the spine (scoliosis especially at the lumbar level. The most spectacular are at the hip level, that is why we made an analytical evaluation only for this joint. To show the importance of physiotherapy for children with hip dysplasia we started from the hypothesis: untimely treatment for children with hip dysplasia has improved results in functional recovery and in obtaining a better stability, without the necessity of orthopedics or surgical interventions. The research methods used in this study are: the observation method, the bibliographic study method, the experimental method, the graphics method and the statistical mathematical method to process the data and to represent the results graphically. In the end, the results obtained are significantly different from the initial evaluations and we came to the conclusion that starting an untimely analytical kinetic treatment and globally personalizing it to every patient improves stability and biomechanical parameters for the hip.

  15. Total Hip Arthroplasty for Hip Fractures

    Monzón, Daniel Godoy; Iserson, Kenneth V.; Jauregui, José; Musso, Carlos; Piccaluga, Francisco; Buttaro, Martin

    2014-01-01

    Introduction: This study aimed to determine the dislocation and reoperation rate, functional outcomes, and the survival rate of the unique subset of very old but lucid and independent patients with hip fractures following a total hip arthroplasty (THA) and geriatric team-coordinated perioperative care. Method: Between 2000 and 2006, previously independent ambulatory patients ≥80 years old presenting with an intracapsular hip fracture were given THAs under the care of an integrated orthopedic surgery–geriatric service. Their fracture-related complications, ambulation, mental status, and survival were followed for 5 to 11 years postinjury. Results: Five years postinjury, 57 (61.3%) patients of the original study group were living. In all, 3 (3.2%) patients had postoperative hip dislocations (and 2 patients had dislocation twice) and 2 reoperations were needed within the first postoperative month. There were no hip dislocations or reoperations after the first year. Radiographs obtained on 88% of the surviving patients at 5 years postoperatively showed that all remained unchanged from their immediate postoperative images. Nearly half of the patients were still able to ambulate as they did preoperatively and their mixed-model equation was statistically unchanged. Conclusion: This study of patients >80 years old with previously good functional status demonstrates that with appropriate surgical (best prosthesis, good operating technique, and regional anesthesia) and geriatric (pre- and postoperative assessments, close follow-up, medication adjustments, and fall-prevention instruction) care, they have few hip dislocations and reoperations, survive postfracture at least as long as their noninjured contemporaries, and continue to function and ambulate as they did prior to their injury.

    The intent of this report is to document a procedure used at LANL for HIP bonding aluminum cladding to U-10Mo fuel foils using a formed HIP can for the Domestic Reactor Conversion program in the NNSA Office of Material, Management and Minimization, and provide some details that may not have been published elsewhere. The HIP process is based on the procedures that have been used to develop the formed HIP can process, including the baseline process developed at Idaho National Laboratory (INL). The HIP bonding cladding process development is summarized in the listed references. Further iterations with Babcock & Wilcox (B&W) to refine the process to meet production and facility requirements is expected.

    Objective Hip arthroscopy in the setting of hip dysplasia is controversial in the orthopaedic community, as the outcome literature has been variable and inconclusive. We hypothesise that outcomes of hip arthroscopy may be diminished in the setting of hip dysplasia, but outcomes may be acceptable in milder or borderline cases of hip dysplasia. Methods A systematic search was performed in duplicate for studies investigating the outcome of hip arthroscopy in the setting of hip dysplasia up to July 2015. Study parameters including sample size, definition of dysplasia, outcomes measures, and re-operation rates were obtained. Furthermore, the levels of evidence of studies were collected and quality assessment was performed. Results The systematic review identified 18 studies investigating hip arthroscopy in the setting of hip dysplasia, with 889 included patients. Criteria used by the studies to diagnose hip dysplasia and borderline hip dysplasia included centre edge angle in 72% of studies but the range of angles were quite variable. Although 89% of studies reported improved post-operative outcome scores in the setting of hip dysplasia, revision rates were considerable (14.1%), with 9.6% requiring conversion to total hip arthroplasty. Conclusion The available orthopaedic literature suggests that although improved outcomes are seen in hip arthroscopy in the setting of hip dysplasia, there is a high rate of re-operation and conversion to total hip arthroplasty. Furthermore, the criteria used to define hip dysplasia vary considerably among published studies. Cite this article: M. Yeung, M. Kowalczuk, N. Simunovic, O. R. Ayeni.

  1. Imaging of hip arthroplasty

    Hip arthroplasty has become a common and still increasing procedure for the treatment of osteoarthritis, advanced head necrosis, post-inflammatory arthritis or rheumatoid arthritis.Radiography is the most important imaging modality for monitoring the normal, asymptomatic hip arthroplasty. Radiographs are obtained at the end of a surgical treatment, to exclude complications like fracture or component misplacement. In the follow-up radiographs are used for the diagnosis of loosening and infection of the hip arthroplasty as well as soft tissue ossification. Together with the history and clinical information, the analysis of morphological findings allows to find the grade of loosening. MRI has been advocated in the diagnosis of infection, in particular in the localisation of soft tissue involvement.Imaging, especially by radiographs, is used for the evaluation of the normal and complicated follow-up of hip arthroplasty.

  5. HIP osteoarthritis and work.

    Harris, E Clare; Coggon, David

    2015-06-01

    Epidemiological evidence points strongly to a hazard of hip osteoarthritis from heavy manual work. Harmful exposures may be reduced by the elimination or redesign of processes and the use of mechanical aids. Reducing obesity might help to protect workers whose need to perform heavy lifting cannot be eliminated. Particularly high relative risks have been reported in farmers, and hip osteoarthritis is a prescribed occupational disease in the UK for long-term employees in agriculture. Even where it is not attributable to employment, hip osteoarthritis impacts importantly on the capacity to work. Factors that may influence work participation include the severity of disease, the physical demands of the job, age and the size of the employer. Published research does not provide a strong guide to the timing of return to work following hip arthroplasty for osteoarthritis, and it is unclear whether patients should avoid heavy manual tasks in their future employment. PMID:26612242

  6. Arthroscopic hip labral repair.

    Philippon, Marc J; Faucet, Scott C; Briggs, Karen K

    2013-05-01

    Labral tears in the hip may cause painful clicking or locking of the hip, reduced range of motion, and disruption to sports and daily activities. The acetabular labrum aids stabilization of the hip joint, particularly during hip motion. The fibrocartilaginous structure extends the acetabular rim and provides a suction seal around the femoroacetabular interface. Treatment options for labral tears include debridement, repair, and reconstruction. Repair of the labrum has been shown to have better results than debridement. Labral refixation is achieved with sutures anchored into the acetabular rim. The acetabular rim is trimmed either to correct pincer impingement or to provide a bleeding bed to improve healing. Labral repair has shown excellent short-term to midterm outcomes and allows patients to return to activities and sports. Arthroscopic rim trimming and labral refixation comprise an effective treatment for labral tears with an underlying diagnosis of femoroacetabular impingement and are supported by the peer-reviewed literature.

    Our aim was to compare hip arthroplasty with internal screw fixation in the repair of intertrochanteric fractures in elderly patients with osteoporosis. Of 112 included patient, 70 (81.81 ± 4.88 years) received hip arthroplasty with a prosthesis specially designed for intertrochanteric fractures, and 42 (83.46 ± 5.11 years) underwent plate-screw fixation. The hip arthroplasty group had significantly longer operation time, intraoperative blood loss, and total volume of blood transfused but had shorter time to beginning weight-bearing (5.94 ± 2.76 vs 23.68 ± 22.01 days) and higher postoperative Harris hip score (91.37 ± 4.80 vs 86.14 ± 5.46). In the arthroplasty group, there were 2 dislocations; and in the plate-screw fixation group, there were 5 internal fixation failures. Hip arthroplasty is preferable to internal fixation in elderly patients (age >80 years) with osteoporosis. PMID:21530148

  12. Hip Arthroscopy: A Brief History.

    Kandil, Abdurrahman; Safran, Marc R

    2016-07-01

    Hip arthroscopy is a fast-growing and evolving field. Like knee and shoulder arthroscopy, hip arthroscopy began as a diagnostic procedure and then progressed to biopsy and resection of abnormalities. Subsequently, it has evolved to repair of various tissues and treatment of underlying causes. As the understanding of the hip joint and its associated pathophysiology grows, indications will continue to expand for this diagnostic and therapeutic modality. This article outlines the historic developments of hip arthroscopy, including advancements in instrumentation and techniques from the days of the first hip arthroscopies to the present day.

    Hip pain is a common condition, and the work-up often includes imaging. This article reviews the normal MR anatomy of the hip and the imaging findings of internal derangements, snapping hip, and femoral acetabular impingement. We will describe the role of MR arthrography in evaluating the patient with suspected labral and articular cartilage abnormalities, as well as the pitfalls in interpretation. We will review the causes of a snapping hip, and the role of sonography in evaluating and guiding treatment of the snapping iliopsoas tendon. We will also review the radiographic and MRI signs of femoroacetabular impingement (FAI), a cause of early degenerative joint disease and hip pain. (orig.)

  14. The athlete's hip and groin.

    Tammareddi, Kumar; Morelli, Vincent; Reyes, Miguel

    2013-06-01

    Groin and hip injuries are seen in athletes who perform quick directional changes and cutting movements. Because forces generated through athletic performance are transferred through the hip, injuries to these areas may limit athletes with mild pain or lead to career-ending injuries. The anatomy of the hip and groin is complex and symptoms often overlap. This article discusses some athletic causes, but other medical conditions may be associated with hip and groin pain as well.

We also used the medical records to validate the diagnosis reported by the orthopedic surgeon to the register. Methods Subjects born after Janua...

  17. Heterotopic ossification after hip arthroscopy.

    Amar, Eyal; Sharfman, Zachary T; Rath, Ehud

    2015-12-01

    Heterotopic ossification (HO) after hip arthroscopy is the abnormal formation of mature lamellar bone within extra skeletal soft tissues. HO may lead to pain, impaired range of motion and possibly revision surgery. There has been a substantial amount of recent research on the pathophysiology, prophylaxis and treatment of HO associated with open and arthroscopic hip surgery. This article reviews the literature on the aforementioned topics with a focus on their application in hip arthroscopy. PMID:27011859

  19. Infant hip sonography: current concepts.

    Harcke, H T; Grissom, L E

    1994-08-01

    Sonography of the infant hip has gained wide acceptance in the decade since its introduction. The two principle techniques of Graf and Harcke have been combined with the proposal of a Dynamic Standard Minimum Examination. Whereas sonography is used increasingly to manage developmental dislocation and/or displasia of the hip, there is no agreement on the use of sonography for universal newborn screening. This article describes in detail the Dynamic Standard Minimum Sonographic Examination of the infant hip. In addition, this article reviews the classification and management of infant hip disorders.

  4. Hip sonography in the newborn

    The authors report the data relative to 1507 cases studied with clinical and US examinations, in the neonatal period, in order to exclude hip dysplasia dislocation. US examination was carried out according to Graf's technique and the newborns were classified according to US hip type, to clinical examination and to possible risk factors. The patients were included in a protocol including orthopedic and US controls. Seventeen treated infants were considered as pathologic. Ten of them had IIc or D hips ar birth; the other 7, with IIa hips at birth, presented a X-ray pathologic hip after the 4th months of life. At about one year of age all infants could normally walk, excpet for one who was being treated with herness. No statistically significant differences were observed between the number of pathologic infants in the risk group (1.7%) and that in the no-risk group (0.8%). Clinical examination of the newborn has low sensitivity in detecting pathologic hips. On the basis of their results, thw authors belive US examination of the newborn to be a valuable screening method to diagnose hip dysplasia/dislocation. Moreover, Graf's morphologic method is the best one for US screening of the hip in the neonatal period

  5. Social inequality and hip fracture

    Harvey, N. C.; Hansen, L.; Judge, A.;

    2015-01-01

    Social inequality appears to be increasing in many countries. We explored whether risk of hip fracture was associated with markers of inequality and whether these relationships changed with time, using data from Danish Health Registries. Methods: All patients 60 years or older with a primary hip...... fracture (ICD10: S720, S721, S722 and S729) were identified from 1 January 1995 to 31 December 2011. Hip fracture patients were matched 1:1 on age, gender and year of fracture to a non-hip fracture control. An individual's education attainment was defined as basic, secondary or higher, and their income was...... taken from their latest registered annual tax return (600,000 DKK). Poisson regression modeling was used to describe the association between income or education with rate of hip fracture, adjusting for confounders (smoking, alcohol, Charlson co-morbidity).

  7. Hip complications following chemoradiotherapy

    Jenkins, P.J.; Sebag Montefiore, D.J.; Arnott, S.J. [Saint Bartholomew`s Hospital, London (United Kingdom)

    1995-12-01

    Chemoradiotherapy protocols are a recent development in the management of tumours where preservation of organ function is important. It is now recognized that such combined treatment may produce adverse effects below the accepted dose thresholds for either modality. This enhancement of toxicity is generally thought to reflect depletion of stem cells within the tissue concerned. We report four patients who have developed avascular necrosis or fractures of the hip following chemoradiotherapy for carcinoma of the vulva or anus. These complications developed after a radiation dose of 4500 cGy in 20 fractions. The possible role of cytotoxic agents in sensitizing bone to radiation damage is discussed, and a novel mechanism is proposed to account for this phenomenon. (author).

  8. Anterior hip pain.

    O'Kane, J W

    1999-10-15

    Anterior hip pain is a common complaint with many possible causes. Apophyseal avulsion and slipped capital femoral epiphysis should not be overlooked in adolescents. Muscle and tendon strains are common in adults. Subsequent to accurate diagnosis, strains should improve with rest and directed conservative treatment. Osteoarthritis, which is diagnosed radiographically, generally occurs in middle-aged and older adults. Arthritis in younger adults should prompt consideration of an inflammatory cause. A possible femoral neck stress fracture should be evaluated urgently to prevent the potentially significant complications associated with displacement. Patients with osteitis pubis should be educated about the natural history of the condition and should undergo physical therapy to correct abnormal pelvic mechanics. "Sports hernias," nerve entrapments and labral pathologic conditions should be considered in athletic adults with characteristic presentations and chronic symptoms. Surgical intervention may allow resumption of pain-free athletic activity. PMID:10537384

  9. Traumatic injuries of the hip.

    Marshall, Nina

    2009-11-01

    Traumatic lesions of the hip in athletes may be clinically challenging because of the overlap in clinical presentation due to differing pathologies and the presence of multiple injuries. Imaging of the hip in the athlete has undergone a recent resurgence of interest and understanding related to the increasing accessibility and use of hip arthroscopy, which expands the treatment options available for intra-articular pathology. MR imaging and MR arthrography have a unique role in diagnosis of these pathologies, guiding the surgeon, arthroscopist, and referring clinician in their management of bony and soft tissue injury.

    1980-01-01

    This paper is a refinement of previous studies in that only suitably radiographed dogs were included in the data base. The rate of hip dysplasia varied widely by breed from five percent in siberian huskies to eighty-three percent in english bulldogs. There was a significant difference in the prevalence of dysplasia within at least two breeds; golden retrievers and old english sheepdogs. Physical size per se did not appear to be an important determinant of hip dysplasia.

  5. The hip in cerebral palsy.

    Bleck, E E

    1980-01-01

    Orthopedic surgery can alleviate the hip flexion, adduction, and medial rotation deformities of the hip and improve the function and appearance of gait. To accomplish this, however, careful examination and prudence in the operative procedure to avoid overdoing and overcorrecting are important. Orthopedic surgery can prevent subluxation and dislocation of the hip before the age of seven years, and consequently repetitive radiographic examinations of the hip in children who have spastic paralysis of the hip musculature should be a routine procedure. Subluxation and dislocation of the hip, when established, can be successfully treated with orthopedic surgical procedures. Physicians must keep in mind that the spastic paralysis of cerebral palsy originates in the brain, and therefore the spasticity cannot be eliminated. The best that can be done is to weaken or remove some muscles as deforming forces and to achieve compromises for continued function. The goal should be optimal independence for the child and adolescent during development, and freedom from pain with deteriorating function due to degenerative arthritis in the adult. PMID:7360505

  6. Neonatal hip dysplasia: Differental diagnosis

    Vukašinović Zoran

    2010-01-01

    Full Text Available Introduction. Hip dysplasia is the elementary form of the developmental dysplasia of the hip (DDH. The diagnosis may be made by the ultrasound examination (types II a-, II b. Objective. The aim of the authors was to define the congenital structural neonatal hip dysplasia, and to differentiate hip hypoplasia, hip dysplasia and teratogenic anomalies. Methods. In all the cases, the uniform clinical and ultrasound tests were performed. All the patients were examined in the neonatal period of life (the first six weeks. The following clinical tests were used: Le Damany-Ortolany, Coleman-Barlow-Palmen and Weissman-Strinović. For the ultrasound examination, the Graph’s method was used. Results. The investigation was performed in the period 2007- 2008. 2,878 neonates were included. The distribution of the sonotypes, according to Graph, was as follows: Ia in 16.17%. Ib in 65.08%; IIa+ in 18.17%, IIc in 0.28%, IId in 0.19%; IIIa in 0.009%, IIIb in 0.02%; and IV in 0.01%. It was found that DDH was 8 times more frequent in girls; located more frequently at the left side than bilaterally. Conclusion. Hip sonoscreening has to be performed in all newborns in the first 72 hours. The suggested follow-up period is six weeks: for the diagnosis - the first three weeks, and for the prevention and treatment - all six weeks.

  7. Pathologic ligamentous constraint of the hip.

    Crowninshield, R D; Johnston, R C; Brand, R A; Pedersen, D R

    1983-12-01

    A mathematic model of the hip capsule and lower extremity musculature was utilized to predict the forces present in the hip ligaments during locomotion. The results demonstrate principles and trends (rather than absolute results) in hip mechanics, the details of which are affected by the associated modeling assumptions. The active stretching of a hip joint capsule tightened by scarring or surgical transfer may appreciably increase the hip contact force. Capsular elements that prevent hip flexion and adduction play a major role in hip contact force exaggeration during common activities. The positive effect of maintaining the hip capsule to reduce total hip component dislocation contrasts with the potential negative effects of restricting joint motion and increasing the joint contact force. Increased joint loading due to capsular restriction may contribute to prosthetic component loosening. PMID:6641064

    2003-03-01

    Purpose: To investigate the clinical and radiological characteristics of osteochondritis dissecans (OD) of the hip and the outcome of this condition after treatment. Material and Methods: Twelve male and 3 female patients with OD were retrospectively studied. Six patients had a history of Legg-Calve-Perthes disease (LCPD) and among them 2 also had had a trauma to the hip. A further 5 had had trauma and 1 a developmental dislocation of the hip (DDH). The remaining 3 patients had no history of previous hip disease or trauma. All patients were examined with plain radiography, 7 with MR, 3 with CT and 2 with hip arthrography. Results: All OD lesions were detected at plain radiography, and most of them were located near the fovea. At MR the lesions had low signal intensity at T1-weighted sequences, and 6/7 had edema or fluid collection in or adjacent to the lesion on T2-weighted sequences. The early treatment in 7 patients was surgery, 2 had had conservative treatment and 6 no treatment. At follow-up 12 years after radiological diagnosis, 5 patients had hip arthrosis, 4 of whom were treated with arthroplasty. All but 3 had reduced hip rotation and all but 2 (with arthroplasty) had load pain. Three of the patients with earlier surgery had not developed arthrosis. Conclusions: OD lesions are usually well seen with plain radiography. There is a great risk of developing early arthrosis and it seems that early surgery is connected with arthrosis development. Thus only symptomatic treatment is recommended.

    Microinstability and ligament teres lesions are emergent topics on the hip pathology. These entities are an increasingly recognized cause of persistent hip pain and should be considered in the differential diagnosis of the patient with hip pain. Conventional (non-arthrographic) CT and MR have a very limited role in the evaluation of these entities. CTa and MRa have emerged as the modalities of choice for pre-operative imaging of ligamentum teres injuries and microinstability. To date, pre-operative imaging detection of these pathologies is not widespread but with appropriate imaging and a high index of suspicion, preoperative detection should improve. This article discusses current concepts regarding anatomy, biomechanics, clinical findings, diagnosis and treatment of ligament teres lesions and microinstability.

  13. Transient Osteoporosis of the Hip

    Farideh Shahandeh

    2009-01-01

    Full Text Available   "nTransient osteoporosis of the hip as originally described in women, almost exclusively involved the left hip with the third trimester of pregnancy. It is now recognized as actually being more common in middle-aged men and affecting either hip. "nSymptoms include severe hip pain and decreased range of motion that resolves spontaneously in 6 to 12 months. The etiology is poorly understood, and the disease has been associated with a type of reflex sympathetic dystrophy syndrome. It may be migratory, with subsequent involvement of the opposite hip on an adjacent joint. Radiological changes may simulate indolent infection, osteonecrosis or infiltrative neoplasm. The underlying pathologic condition appears to be bone marrow reaction or edema. Current terminology may refer to this entity as transient bone marrow edema syndrome. Radiographs usually show osteopenia, and bone scan reveals intense activity locally within the femoral head – unlike A.V.N which often displays central photopenia. MRI demonstrates diffuse marrow abnormalities that usually extend from the subchondral femoral head to the inter trochanteric and sub trochanteric regions. There is low signal intensity on T1 weighted MR images and high signal intensity on T2 weighted sequences. The MRI changes reflect the nonspecific marrow reaction or edema that is present. Focal osteoporotic bone marrow defects in the subchondral region or subtle femoral head flattening should be searched for diligently on MR images. Unlike the case with A.V.N. , these defects are usually absent in transient osteoporosis.   

  14. Traumatic hip dislocations in children

    Objectives: To evaluate clinical features, treatment and relationship to the time period between dislocation, reduction and early complications of traumatic dislocation of hip in children. Methods: Case series conducted at Jinnah Post Graduate Medical Centre Karachi from July 2005 to August 2009. Children with traumatic hip dislocation up to fifteen years of age who presented in last four years were included in this study. Their clinical information, etiology, associated injuries, duration, method of reduction and early complications are evaluated through emergency room proforma and indoor record. Follow up of patient was updated in outpatient department. Results: We had eight patients, six boys and two girls. Youngest 2.4 years and eldest was 12 years with mean age of 6.2 +- 3.8 years. All presented with posterior hip dislocation. Etiology was road traffic accident in two and history of fall in remaining six patients. Average duration of time between dislocation and reduction was 19 hours range 3-72 hours. Dislocated hips were reduced under General Anaesthesia in two patients and under sedation analgesia in six patients. No complications were noted in eight cases with mean 18.75 +- 13.23 months follows up. Conclusion: Traumatic hip dislocation in children is not rare. Slight trauma causes dislocation in younger age and immediate closed reduction and Immobilization reduces complications. (author

  19. Developmental hip dysplasia in adolescence

    Vukašinović Zoran

    2009-01-01

    Full Text Available The authors define adolescence and developmental dysplasia of the hip (DDH. Special attention is paid to pathological findings characteristic of DDH in adolescence (unrecognized and untreated DDH; treated DDH, but non-terminated treatment; DDH diagnosed with delay, inadequately treated, with complications. The authors emphasise that DDH treatment has to be successfully terminated well before the adolescence; possibilities are explained on management modes at the time of adolescence, and possible persons guilty for the persistence of later hip problems are indicated. Based on the authors' experience and having in mind all surgical possibilities for the treatment (pelvic osteotomies, femoral osteotomies, trochanteroplasties, leg length equalization procedures the authors propose treatment protocols. The intention is to provide better treatment results and to prevent secondary hip arthrosis. Furthermore, how to improve the struggle against DDH is suggested.

  20. Cementless Hydroxyapatite Coated Hip Prostheses

    Antonio Herrera

    2015-01-01

    Full Text Available More than twenty years ago, hydroxyapatite (HA, calcium phosphate ceramics, was introduced as a coating for cementless hip prostheses. The choice of this ceramic is due to its composition being similar to organic apatite bone crystals. This ceramic is biocompatible, bioactive, and osteoconductive. These qualities facilitate the primary stability and osseointegration of implants. Our surgical experience includes the implantation of more than 4,000 cementless hydroxyapatite coated hip prostheses since 1990. The models implanted are coated with HA in the acetabulum and in the metaphyseal area of the stem. The results corresponding to survival and stability of implants were very satisfactory in the long-term. From our experience, HA-coated hip implants are a reliable alternative which can achieve long term survival, provided that certain requirements are met: good design selection, sound choice of bearing surfaces based on patient life expectancy, meticulous surgical technique, and indications based on adequate bone quality.

  1. MRI of the hip joint

    Magnetic resonance imaging (MRI) is performed to diagnose many pathologic conditions affecting the hip joint. Either conventional MRI (without contrast enhancement of the joint cavity) or MR arthrography is used to detect and most accurately differentiate hip joint pathologies. Conventional MRI is performed in cases of bone marrow edema, necrosis, arthrosis and especially the so-called ''activated arthrosis'', as well as in inflammatory and tumorous entities. MR arthography, which has only recently become available for use, is excellently suited for diagnosing lesions of the acetabular labrum, cartilage lesions, and free articular bodies. This article provides an overview about MRI characteristics and their accuracy of hip joint diseases and the impact on the therapeutic procedure. (orig.)

    Congenital hip luxation is a disorder which evolves in time. Teratological hip dislocation is a distinct form of hip luxation, which usually appears with other disorders. These hips are dislocated before birth. In this thesis we will try to elaborate a recovery program, through physical exercises, which will help us realize our treatment objectives: diminishing articular stiffness, increasing articular mobility, increasing muscle strength, recalibration of agonist and antagonist balances and ...

  5. Hip arthroscopy. The supine position.

    Byrd, J W

    2001-10-01

    Hip arthroscopy is an effective technique. It can be performed successfully either supine or in the lateral position, but there appear to be modest advantages of the supine approach. Arthroscopy offers a less invasive alternative to arthrotomy for traditionally recognized forms of hip pathology, such as loose bodies or impinging osteophytes. Arthroscopy also offers a method of treatment for many conditions (including labral tears, acute articular injuries, and damage to the ligamentum teres) that previously went unrecognized and untreated. In the past, these patients were simply resigned to living within the constraints of their symptoms. Several dictums about hip arthroscopy must be acknowledged. First, the key to a successful outcome lies in proper patient selection. A technically well-executed procedure will fail when performed for the wrong reason, or when the outcome fails to meet the patient's expectations. Second, the patient must be properly positioned for the procedure to go well. Poor positioning will assure a difficult procedure. Third, simply gaining access to the hip joint is not an outstanding technical accomplishment. The paramount issue is accessing the joint in as atraumatic a fashion as possible. Due to its constrained architecture and dense soft tissue envelope, the potential for inadvertent iatrogenic scope trauma is significant and, perhaps unavoidable to some extent. Therefore, every reasonable step should be taken to keep this concern to a minimum. Perform the procedure as carefully as possible and be certain that it is being performed for the right reason. After accessing the joint, the techniques of operative arthroscopy for the hip employ existing strategies established in other joints. Because of the restraints imposed by the hip, however, technical deficiencies may be more apparent. PMID:11675882

    1995-01-01

    A randomized block design was used to compare the Singh index, the cortical index of the femoral neck and the lateral cortical width of the femur of a group of patients with femoral neck fracture, a group with intertrochanterie fracture, and a normal contrrol group among a total of 102 postmenopausal women. The three irtdiees in fracture grotlp were very significantly (P<0. 01) or significantly (P<0. 05) different from those in the normal control subjects. The importance of osteopomosis in hip fracture of the aged is con-firmed. Radiographic measurement of bone mass was found to have some predictive value for the risk of hip fracture.

  10. Poor fixation of the Mittelmeier hip prosthesis

    We have evaluated 30 Mittelmeier hips on an average 3.3 years after the operation. Seven hips had been revised because of severe pain and mechanical loosening and one because of fracture of the threaded ceramic cup. Only five of the remaining 22 hips were asymptomatic. There was radiographic migration of the acetabular and femoral components in more than one third of the hips and increased scintimetric values around the femoral component in all but two hips. Unfavorable design of the Mittelmeier prosthesis may be an important etiologic factor contributing to poor component fixation and inferior clinical results. (author)

    Congenital hip dysplasia and hip dislocation are relatively common pathological conditions of the musculoskeletal system in infants. An early and certain diagnosis can now be achieved by sonographic hip screening within the framework of screening examination programs. This early diagnostic procedure in infants is essential particularly for a conservative treatment strategy. Therefore, apart from possessing in-depth knowledge, training of the examiner in specialist courses is of central importance. This article presents an overview of the entity of congenital hip dysplasia and hip dislocation, the diagnostics and treatment with special emphasis on recent developments. PMID:26489825

  18. Imaging of hip joint arthroplasty

    The hip joint is the largest joint in the human body and consequently, its evaluation by diagnostic imaging is highly important. This includes imaging of hip joint arthroplasty, which is used to avoid joint immobility following a wide spectrum of diseases, such as end-stage degenerative disease, avascular necrosis of the femoral head or post-traumatic fractures. Conventional radiography is still the standard imaging modality for the evaluation of hip arthroplasty both directly following surgery and for periodical follow-up. In the majority of cases conventional radiography enables adequate assessment of early and late complications that can arise following hip arthroplasty, such as loosening, prosthetic or periprosthetic fracture, luxation, infection and soft tissue calcification. If the diagnosis cannot be established by means of radiography, advanced imaging methods such as computed tomography (CT) and magnetic resonance imaging (MRI), with or without injection of contrast media, may provide additional information. This is particularly true for the depiction of inflammatory processes. Regardless of the imaging modality used patients' clinical symptoms must also be taken into account in order to establish the correct diagnosis. (orig.)

  19. Hip Imaging in Athletes: Sports Imaging Series.

    Agten, Christoph A; Sutter, Reto; Buck, Florian M; Pfirrmann, Christian W A

    2016-08-01

    Hip or groin pain in athletes is common and clinical presentation is often nonspecific. Imaging is a very important diagnostic step in the work-up of athletes with hip pain. This review article provides an overview on hip biomechanics and discusses strategies for hip imaging modalities such as radiography, ultrasonography, computed tomography, and magnetic resonance (MR) imaging (MR arthrography and traction MR arthrography). The authors explain current concepts of femoroacetabular impingement and the problem of high prevalence of cam- and pincer-type morphology in asymptomatic persons. With the main focus on MR imaging, the authors present abnormalities of the hip joint and the surrounding soft tissues that can occur in athletes: intraarticular and extraarticular hip impingement syndromes, labral and cartilage disease, microinstability of the hip, myotendinous injuries, and athletic pubalgia.

  20. Techniques and results for open hip preservation

    David eLevy

    2015-12-01

    Full Text Available While hip arthroscopy grows in popularity, there are still many circumstances under which open hip preservation is most appropriately indicated. This article specifically reviews open hip preservation procedures for a variety of hip conditions. Femoral acetabular impingement may be corrected using an open surgical hip dislocation. Acetabular dysplasia may be corrected using a periacetabular osteotomy. Acetabular protrusio may require surgical hip dislocation with rim trimming and a possible valgus intertrochanteric osteotomy. Legg-Calve ́-Perthes disease produces complex deformities that may be better served with osteotomies of the proximal femur and/ or acetabulum. Chronic slipped capital femoral epiphysis (SCFE may also benefit from a surgical hip dislocation and/or proximal femoral osteotomy.

  4. Economic viability of geriatric hip fracture centers.

    Clement, R Carter; Ahn, Jaimo; Mehta, Samir; Bernstein, Joseph

    2013-12-01

    Management of geriatric hip fractures in a protocol-driven center can improve outcomes and reduce costs. Nonetheless, this approach has not spread as broadly as the effectiveness data would imply. One possible explanation is that operating such a center is not perceived as financially worthwhile. To assess the economic viability of dedicated hip fracture centers, the authors built a financial model to estimate profit as a function of costs, reimbursement, and patient volume in 3 settings: an average US hip fracture program, a highly efficient center, and an academic hospital without a specific hip fracture program. Results were tested with sensitivity analysis. A local market analysis was conducted to assess the feasibility of supporting profitable hip fracture centers. The results demonstrate that hip fracture treatment only becomes profitable when the annual caseload exceeds approximately 72, assuming costs characteristic of a typical US hip fracture program. The threshold of profitability is 49 cases per year for high-efficiency hip fracture centers and 151 for the urban academic hospital under review. The largest determinant of profit is reimbursement, followed by costs and volume. In the authors’ home market, 168 hospitals offer hip fracture care, yet 85% fall below the 72-case threshold. Hip fracture centers can be highly profitable through low costs and, especially, high revenues. However, most hospitals likely lose money by offering hip fracture care due to inadequate volume. Thus, both large and small facilities would benefit financially from the consolidation of hip fracture care at dedicated hip fracture centers. Typical US cities have adequate volume to support several such centers. PMID:24579222

  6. Measurement outcomes from hip simulators.

    de Villiers, Danielle; Shelton, Julia C

    2016-05-01

    Simulation of wear in total hip replacements has been recognised as an important factor in determining the likelihood of clinical success. However, accurate measurement of wear can be problematic with factors such as number and morphology of wear particles produced as well as ion release proving more important in the biological response to hip replacements than wear volume or wear rate alone. In this study, hard-on-hard (CoCr alloy, AgCrN coating) and hard-on-soft (CoCr alloy and CrN coating on vitamin E blended highly cross-linked polyethylene) bearing combinations were tested in an orbital hip simulator under standard and some adverse conditions. Gravimetric wear rates were determined for all bearings, with cobalt and where applicable, silver release determined throughout testing. Isolation of wear particles from the lubricating fluid was used to determine the influence of different bearing combinations and wear conditions on particle morphology. It was found that cobalt and silver could be measured in the lubricating fluid even when volumetric wear was not detectable. In hard-on-hard bearings, Pearson's correlation of 0.98 was established between metal release into the lubricating fluid and wear volume. In hard-on-soft bearings, coating the head did not influence the polyethylene wear rates measured under standard conditions but did influence the cobalt release; the diameter influenced both polyethylene wear and cobalt release, and the introduction of adverse testing generated smaller polyethylene particles. While hip simulators can be useful to assess the wear performance of a new material or design, measurement of other outcomes may yield greater insight into the clinical behaviour of the bearings in vivo.

  14. Life Estimation of Hip Joint Prosthesis

    Desai, C.; Hirani, H.; Chawla, A.

    2014-11-01

    Hip joint is one of the largest weight-bearing structures in the human body. In the event of a failure of the natural hip joint, it is replaced with an artificial hip joint, known as hip joint prosthesis. The design of hip joint prosthesis must be such so as to resist fatigue failure of hip joint stem as well as bone cement, and minimize wear caused by sliding present between its head and socket. In the present paper an attempt is made to consider both fatigue and wear effects simultaneously in estimating functional-life of the hip joint prosthesis. The finite element modeling of hip joint prosthesis using HyperMesh™ (version 9) has been reported. The static analysis (load due to the dead weight of the body) and dynamic analysis (load due to walking cycle) have been described. Fatigue life is estimated by using the S-N curve of individual materials. To account for progressive wear of hip joint prosthesis, Archard's wear law, modifications in socket geometry and dynamic analysis have been used in a sequential manner. Using such sequential programming reduction in peak stress has been observed with increase in wear. Finally life is estimated on the basis of socket wear.

  15. COMPLEX FUNCTIONAL ASSESSMENT OF THE HIP JOINT.

    Maya S. Krastanova

    2015-09-01

    Full Text Available Introduction: In relation to the study reporting the effects of applying phased complex rehabilitation in patients with total hip arthroplasty, it has been concluded that the everyday clinical practice in Bulgaria does not apply complex examination, giving an objective picture about the extent of functional status of patients with trauma and diseases of the hip. Aim: The main goal of this report is to present a test which incorporates all known and routine research and in which the total number of points determines the functional status of patients with trauma and diseases of the hip. Material and Methods: Based on the Hip dysfunction and Osteoarthritis Outcome Score, the Harris Hip Score modified test, scale D’Aubigne and Postel and Iowa’s test for complex functional evaluation of the hip joint, we have developed a test including information about the degree of pain; goniometry and manual muscle testing of the hip; locomotor test – type of gait and adjuvants; test for Daily Activities of Life. The test has been developed on the basis of expert assessment by doctors and physiotherapists of the proposed indicators for evaluation and determination of the weighting factors’ contribution to the general condition of the patient. Conclusion: The developed and tested method of complex functional assessment of the hip joint enables our colleagues, dealing with trauma and diseases of the hip, to use it in various research and scientific projects, as well as in general medical practice.

    2010-11-01

    Full Text Available Abstract Background There have been reports both supporting and refuting an inverse relationship between hip fracture and hip osteoarthritis (OA. We explore this relationship using a case-control study design. Methods Exclusion criteria were previous hip fracture (same side or contralateral side, age younger than 60 years, foreign nationality, pathological fracture, rheumatoid arthritis and cases were radiographic examinations were not found in the archives. We studied all subjects with hip fracture that remained after the exclusion process that were treated at Akureyri University Hospital, Iceland 1990-2008, n = 562 (74% women. Hip fracture cases were compared with a cohort of subjects with colon radiographs, n = 803 (54% women to determine expected population prevalence of hip OA. Presence of radiographic hip OA was defined as a minimum joint space of 2.5 mm or less on an anteroposterior radiograph, or Kellgren and Lawrence grade 2 or higher. Possible causes of secondary osteoporosis were identified by review of medical records. Results The age-adjusted odds ratio (OR for subjects with hip fracture having radiographic hip OA was 0.30 (95% confidence interval [95% CI] 0.12-0.74 for men and 0.33 (95% CI 0.19-0.58 for women, compared to controls. The probability for subjects with hip fracture and hip OA having a secondary cause of osteoporosis was three times higher than for subjects with hip fracture without hip OA. Conclusion The results of our study support an inverse relationship between hip fractures and hip OA.

    The objective of this study was to define, in unilateral hip osteoarthritis (OA), factors predicting the outcome of the other hip. We examined the anteroposterior radiographs of the pelvis of 95 white patients with unilateral idiopathic (56 patients) or secondary to congenital hip diseases (39 patients) OA. The other hip was free from symptoms (pain or limping) at the initial examination and without radiographic evidence of OA; it was what we call a ''normal'' hip. Two parameters were evaluated: (1) the type of osteoarthritis of the involved hip and (2) the range of four radiographic indices of the contralateral hip: the sourcil inclination (weight-bearing surface), the acetabular angle, the Wiberg's center-edge angle, and the neck-shaft angle. Follow-up radiographs for the hips that remained OA-free were available for 10 to 35 years and for those that developed OA, at the time of initial symptoms, range 2 to 31 years. Logistic regression analysis showed that the presence of idiopathic OA in one hip had a statistically significant effect on the development of OA on the other hip (p<0.001). Minor deviations of radiographic indices of the contralateral hip is not a predictive factor for its outcome. When the radiographic indices are examined together with the pathology of the involved hip, only WBS was shown to have a significant effect to the development of OA and its type (p < 0.001). The following conclusions can be drawn from this study: 1. Patient with idiopathic OA of one hip is at increased risk of developing OA in the other hip. 2. The outcome of the other hip cannot be predicted only on the basis of the evaluation of its radiographic indices. 3. Among the different indices, WBS seems to have a strong influence toward the development of OA. (orig.)

  2. The hip-spine connection: understanding its importance in the treatment of hip pathology.

    Redmond, John M; Gupta, Asheesh; Nasser, Rima; Domb, Benjamin G

    2015-01-01

    EDUCATIONAL OBJECTIVES As a result of reading this article, physicians should be able to: 1. Discuss the kinematic relationship between the hip and lumbar spine. 2. Explain the innervation of the hip and lumbar spine and how they relate to one another. 3. Recognize the effect of hip disease on the lumbar spine in an athletic population, prior to the onset of degenerative changes. 4. Describe an algorithm for diagnosis and treatment of patients who present with concomitant hip and lumbar spine pain. The hip and lumbar spine are closely related and can create similar patterns of pain and dysfunction. Diagnosis and treatment of hip and spine-related conditions can be challenging due to symptom overlap. Successful evaluation and treatment of hip and lumbar spine conditions requires a thorough understanding the hip-spine connection. Historically the hip-spine connection has been considered in the context of arthrosis; however, the hip-spine connection also needs to be considered in a younger athletic population. The purpose of this review is to describe the hip-spine connection, discuss the clinical implications of this connection, and offer an approach to diagnosis and treatment. PMID:25611411

    1984-06-01

    The radiology of total hip replacement (THR) and its complications is reviewed in conjunction with a long-term follow-up study on 402 patients with 501 prostheses. The indications, contraindications, biomechanics, and operative management of these patients is discussed. Clinical complications such as deep vein thrombosis, pulmonary embolism, and hemorrhage are mentioned. Postoperative infections including granulomatous pseudotumors, dislocations and fractures, true loosening of the prosthesis, and heterotopic bone formation (HBF) are discussed and illustrated. The importance of differentiating the lucent line from true loosening is stressed. Mechanical and other clinical complications which are largely ignored by radiologists are also discussed. The uses of arthrography and bone scanning are included.

  5. Biomechanics of the Hip Capsule and Capsule Management Strategies in Hip Arthroscopy.

    Nepple, Jeffrey J; Smith, Matthew V

    2015-12-01

    Recent advances in our understanding of the function of the hip capsule have clarified its importance to normal hip function and kinematics. The iliofemoral ligament is the primary stabilizing structure for controlling anterior translation and external rotation of the hip, and is violated by the arthroscopic interportal capsulotomy. Microinstability of the hip occurring after surgical trauma remains a poorly defined clinical entity. In certain at-risk populations, capsular repair should be considered as part of an arthroscopic hip procedure to achieve optimal outcomes and avoid iatrogenic instability (dislocation or microinstability). Despite a lack of conclusive evidence-based indications, we recommend capsular repair in the settings of borderline hip dysplasia (or dysplastic variants such as increased femoral anteversion), hip hypermobility, connective tissue disorders, and traumatic or atraumatic instability. With careful attention to arthroscopic capsular management, adequate exposure can be achieved and reproducibly allow for an effective capsular repair when indicated. PMID:26524549

    2013-07-01

    Full Text Available Total hip replacement is a reconstructive procedure that has improved the management of those diseases of the hip joint that have responded poorly to conventional medical therapy. Conventional, primary total hip replacement is a durable operation in the majority of patients. A hip replacement is a mechanical device with parts that are assembled before and during the operation. But the possible complications of total hip arthroplasty, and its clinical performance over time, is a challenging occasion to the surgeons, and such a challenge we faced with our presenting patient. A 68 year old lady with history of cemented bipolar hemiarthroplasty done in a tertiary care hospital, due to fracture neck of the left femur having the history of diabetes, chronic kidney disease, heart disease, anaemia, and mental disorders presented with loosened prosthesis, thinning of medial proximal cortex of the femur which had broken within few months after surgery. She complained of painful walking at left hip joint. There was also evidence of chronic infective and degenerative arthritis of acetabular component of the affected hip joint. Cemented revision total hip replacement surgery was performed with expert multidisciplinary involvement. On 2nd postoperative day the patient was allowed to walk on operated limb with the aid of walker. On 12th postoperative day all the stitches were removed and wound was found healthy.

  11. TREATMENT OF NEUROLOGICAL CONGENITAL HIP LUXATION

    2015-11-01

    Full Text Available Congenital hip luxation is a disorder which evolves in time. Teratological hip dislocation is a distinct form of hip luxation, which usually appears with other disorders. These hips are dislocated before birth. In this thesis we will try to elaborate a recovery program, through physical exercises, which will help us realize our treatment objectives: diminishing articular stiffness, increasing articular mobility, increasing muscle strength, recalibration of agonist and antagonist balances and reeducating gait. The specific objectives of the study consist of the particularization of the recovery programs based on age, illness stage (dysplasia or luxation and either surgical or non-surgical intervention. To show the importance of physiotherapy in gait rehabilitation of a child with hip dislocation we started from the hypothesis: using an adequate rehabilitation program after an individualized methodology, optimizes the functional recovery and ensures the gains of hip stability and the formation of an engram of gait as close as it could be to the normal one. We present a case of neurological congenital hip dislocation where the treatment initiated early is showing good results. Results obtained are significantly different and we came to the conclusion that starting an untimely analytical kinetic treatment and globally personalizing it to every patient has better biomechanical results for the hip.

  15. Minimally invasive medial hip approach.

    Chiron, P; Murgier, J; Cavaignac, E; Pailhé, R; Reina, N

    2014-10-01

    The medial approach to the hip via the adductors, as described by Ludloff or Ferguson, provides restricted visualization and incurs a risk of neurovascular lesion. We describe a minimally invasive medial hip approach providing broader exposure of extra- and intra-articular elements in a space free of neurovascular structures. With the lower limb in a "frog-leg" position, the skin incision follows the adductor longus for 6cm and then the aponeurosis is incised. A slide plane between all the adductors and the aponeurosis is easily released by blunt dissection, with no interposed neurovascular elements. This gives access to the lesser trochanter, psoas tendon and inferior sides of the femoral neck and head, anterior wall of the acetabulum and labrum. We report a series of 56 cases, with no major complications: this approach allows treatment of iliopsoas muscle lesions and resection or filling of benign tumors of the cervical region and enables intra-articular surgery (arthrolysis, resection of osteophytes or foreign bodies, labral suture).

  16. Analysis of hip perfusion at early and reversible stages of aseptic hip necrosis

    Aim: A proper early diagnosis of aseptic hip necrosis is very important for further therapy.Since there has always been a question of the amount of perfusion in hips at different stages of aseptic hip necrosis we tried to impartially examine the perfusion in hips at early and reversible stages of aseptic hip necrosis. Material and Methods:Study included 143 patients with aseptic hip necrosis.The 550-740 MBq of Tc-99m-DPD were on bolus injected.All patients were subjected to 3-phase scintigraphy of hips and quantitative calculation of relative perfusion in the artery phase (3T) at early and repeated at reversible stages of aseptic hip necrosis. Results: At the early stage of aseptic hip necrosis the obtained 3T was decreased from 0.94-0.69 (3T=0.80).Scintigrams showed a moderate increase or diffuse accumulation. At the reversible stages we obtained 3T decreased from 0.92-0.71 (3T=0.79) thus evidencing hypoperfusion.Scintigrams showed an diffuse increased accumulation. Conclusion: With the aseptic hip necrosis quantitative analysis of perfusion in the artery phase-3T indicates that the perfusion is decreased at all stages of the process which however shows a significantly falling trend with the progress of the disease

  17. Reconstruction of the Acetabulum in Developmental Dysplasia of the Hip in Total Hip Replacement

    Vasileios Sakellariou

    2014-09-01

    Full Text Available Developmental dysplasia of the hip (DDH or congenital hip dysplasia (CDH is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of symptoms is 34.5 years for dysplastic DDH, 32.5 years for low dislocation, 31.2 years for high dislocation with a false acetabulum, and 46.4 years for high dislocation without a false acetabulum. Thorough understanding of the bony and soft tissue deformities induced by dysplasia is crucial for the success of total hip arthroplasty. It is important to evaluate the existing acetabular deformity three-dimensionally, and customize the correction in accordance with the quantity and location of ace tabular deficiencies. Acetabular reconstruction in patients with DDH is hallenging. Interpretation of published data is difficult and should be done with caution because most series include patients with different types of hip disease. In general, the complication rate associated with THA is higher in patients with hip dysplasia than it is in patients with osteoarthritis. Overall, clinical and functional outcomes following THA in patients hip dysplasia (DDH differ from those treated for primary hip osteoarthritis, possibly due to the lower age and level of activity. Although function scores decline with age, the scores for pain and range of motion presented with a statistically significant improvement in the long-term.

  19. Mechanical Evaluation of Polymer Composite Hip Protectors

    Jose Daniel Diniz Melo

    2010-01-01

    Full Text Available Hip fractures often result in serious health implications, particularly in the geriatric population, and have been related to long-term morbidity and death. In most cases, these fractures are caused by impact loads in the area of the greater trochanter, which are produced in a fall. This work is aimed at developing hip protectors using composite materials and evaluating their effectiveness in preventing hip fractures under high impact energy (120 J. The hip protectors were developed with an inner layer of energy absorbing soft material and an outer rigid shell of fiberglass-reinforced polymer composite. According to the experimental results, all tested configurations proved to be effective at reducing the impact load to below the average fracture threshold of proximal femur. Furthermore, an addition of Ethylene Vinyl Acetate (EVA to the impacted area of the composite shell proved to be beneficial to increase impact strength of the hip protectors. Thus, composite hip protectors proved to be a viable alternative for a mechanically efficient and cost-effective solution to prevent hip fractures.

  20. Traumatic inferior hip dislocation: a rare adult case with ipsilateral bifocal hip fracture

    El Hajj Moussa, Majd; Tawk, Charbel; Hoyek, Fadi; Lahoud, Jean-Claude

    2016-01-01

    Inferior dislocation is a rare type of hip dislocation, especially in adults. Few cases have been reported; most of them were isolated. This is the case of a traumatic adult hip dislocation after a road traffic accident. Reduction was made under general anaesthesia; a CT-Scan after the reduction showed a bifocal non-displaced hip fracture. In this article, we present a small review of the literature and we discuss the possible mechanism of hip dislocation. We found through our case study that this condition is not exclusive to children and CT-Scan is mandatory after the reduction of hip dislocation to eliminate any associated injury. To our knowledge, a bifocal hip fracture has not previously been documented, in the English language literature. PMID:27141043

  1. Comparison of acetabular reamings during hip resurfacing versus uncemented total hip arthroplasty.

    Brennan, S A

    2009-04-01

    PURPOSE: To compare the quantity of bone removed from the acetabulum during resurfacing hip arthroplasty versus uncemented total hip arthroplasty (THA). METHODS: 62 consecutive patients with osteoarthritis of the hip were prospectively studied. 24 men and 7 women aged 40 to 86 (mean, 59) years underwent Birmingham hip resurfacing. 13 men and 18 women aged 34 to 88 (mean, 61) years underwent uncemented THA using the trident acetabular cup. Obese elderly women at risk of femoral neck fracture and patients with large subchondral pseudocysts or a history of avascular necrosis of the femoral head were assigned to uncemented THA. Acetabular reamings were collected; marginal osteophytes were not included. The reamings were dehydrated, defatted, and weighed. RESULTS: The mean weight of acetabular reamings was not significantly different between patients undergoing hip resurfacing and uncemented THA (p=0.57). CONCLUSION: In hip resurfacing, the use of an appropriately small femoral component avoids oversizing the acetabular component and removal of excessive bone stock.

  2. Pain in the hip joint

    Yuri Aleksandrovich Olyunin

    2013-01-01

    Full Text Available Pathological changes that develop in the hip joints (HJ have different origins and mechanisms of development, but their main manifestation is pain. The nature of this pain cannot be well established on frequent occasions. The English-language medical literature currently classifies such disorders as greater trochanter pain syndrome (GTPS. Its major signs are chronic pain and local palpatory tenderness in the outer part of HJ. The development of GTPS may be associated with inflammation of the synovial bursae situated in the greater tronchanter, as well as with tendinitis, myorrhexis, iliotibial band syndrome, and other local changes in the adjacent tissues or with systemic diseases. So GTPS may be characterized as regional pain syndrome that frequently mimics pain induced by different diseases, including myofascial pain syndrome, osteoarthrosis, spinal diseases, etc.

  3. Complications after total hip replacement

    Complications seen after long-term follow-up examinations of total hip replacement should be treated immediately and completely. In the past decade a considerable increase in revisions has been noted. Radiographic assessment may be regarded as an effective means in diagnosing prosthetic complications from the surgeon's point of view. Examples are given. The difficulties in radiographic assessment of complications after cementless implanation or cemented prostheses without contrast media are mentioned. Prosthesis-related complications, such as mechanical loosening, infection with and without loosening, fatigue fractures and wear, fractures of the femur or pelvis, dislocations and surgical failures, are illustrated, as are clinical courses with gross loss of bone stock after repeated surgery and delayed revisions. Complications not related to the prosthesis such as periarticular ossification, muscle deficiencies, and nervous and vascular lesions are also explained using examples. (orig.)

    Imaging of the hip abductors plays an increasing role for the evaluation of greater trochanteric pain in patients with and without total hip arthroplasty. This review article addresses the anatomy of the hip abductors and their intervening bursae. It highlights different possible imaging appearances such as tendinopathy or partial and full thickness tears of the gluteal tendons. Muscle atrophy or fatty degeneration of the gluteal muscles is an important reason for limping. Inflammatory diseases such as hydroxyapatite crystal deposition disease or spondylarthritis have to be considered. Knowledge of these different entities is important to achieve optimal treatment and outcomes.

  9. Metal on metal hip resurfacing versus uncemented custom total hip replacement - early results

    Muirhead-Allwood Sarah K

    2010-02-01

    Full Text Available Abstract Introduction There is no current consensus on the most appropriate prosthesis for treating symptomatic osteoarthritis (OA of the hip in young, active patients. Modern metal on metal hip resurfacing arthroplasty (HR has gained popularity as it is theoretically more stable, bone conserving and easier to revise than total hip arthroplasty. Early results of metal on metal resurfacing have been encouraging. We have compared two well matched cohorts of patients with regard to function, pain relief and patient satisfaction. Methods This prospective study compares 2 cohorts of young, active patients treated with hip resurfacing (137 patients, 141 hips and custom uncemented (CADCAM stems (134 patients, 141 hips. All procedures were performed by a single surgeon. Outcome measures included Oxford, WOMAC and Harris hip scores as well as an activity score. Statistical analysis was performed using the unpaired student's t-test. Results One hundred and thirty four and 137 patients were included in the hip replacement and resurfacing groups respectively. The mean age of these patients was 54.6 years. The mean duration of follow up for the hip resurfacing group was 19.2 months compared to 13.4 months for the total hip replacement group. Pre operative oxford, Harris and WOMAC scores in the THA group were 41.1, 46.4 and 50.9 respectively while the post operative scores were 14.8, 95.8 and 5.0. In the HR group, pre- operative scores were 37.0, 54.1 and 45.9 respectively compared to 15.0, 96.8 and 6.1 post operatively. The degree of improvement was similar in both groups. Conclusion There was no significant clinical difference between the patients treated with hip resurfacing and total hip arthroplasty in the short term.

  10. UNCEMENTED PRIMARY TOTAL HIP ARTHROPLASTY FOR OSTEONECROSIS OF HIP WITH SECONDARY OSTEOARTHRITIS IN YOUNG ADULTS

    Chatla

    2016-03-01

    Full Text Available BACKGROUND Osteonecrosis of the femoral head is a progressive disease that generally affects patients in the third through fifth decade of life, if left untreated. Currently, 18% of all Total Hip Arthroplasty performed in USA are done for Osteonecrosis.(1 The aetiology for the Osteonecrosis varies from idiopathic, alcohol intoxication, steroid abuse or due to childhood hip disorders and hip trauma. We have selected 40 patients suffering from advanced femoral head osteonecrosis with subchondral collapse leading to Osteoarthritis of hip in young adults, treated by uncemented primary total hip replacement. This study is aimed to suggest that uncemented total hip arthroplasty can be applied predictably to this younger, potentially more active patient population. MATERIAL AND METHODS We have done 54 uncemented primary hips in 40 cases with mean follow-up of 5.5 years. The average age of the patient at the time of surgery was 43 years. All the hips are clinically and radiologically examined both pre- and post-operatively. All the cases are operated through postero-lateral approach and have used the fully Hydroxyapatite coated femoral straight stem designed for press fit insertion and hemispherical HA-coated cup inserted with press fit and in few cases we used an HA-coated screw. The patients are under regular follow-up. RESULTS All the patients are reviewed at 6 weeks, 3 months, 6 months and yearly thereafter. The clinical and functional status was recorded using the Harris Hip Score and WOMAC Hip Score. The mean Harris score has improved from an average of 44 points to an average of 93 points postoperatively; 94% showed good-to-excellent results, 2% of cases had shortening, one case developed hip dislocation after two weeks due to unguarded physiotherapy. CONCLUSION The short-term results of cementless total hip arthroplasty in patients with Osteonecrosis of the femoral head were encouraging. We await further follow-up to see if these promising

    2012-01-01

    Background The results of primary total hip arthroplasties (THAs) after pediatric hip diseases such as developmental dysplasia of the hip (DDH), slipped capital femoral epiphysis (SCFE), or Perthes' disease have been reported to be inferior to the results after primary osteoarthritis of the hip (OA.......9%) were operated due to pediatric hip diseases (3.1% for Denmark, 8.8% for Norway, and 1.9% for Sweden) and 288,435 THAs (77.8%) were operated due to OA. Unadjusted 10-year Kaplan-Meier survival of THAs after pediatric hip diseases (94.7% survival) was inferior to that after OA (96.6% survival......). Consequently, an increased risk of revision for hips with a previous pediatric hip disease was seen (risk ratio (RR) 1.4, 95% CI: 1.3-1.5). However, after adjustment for differences in sex and age of the patients, and in fixation of the prostheses, no difference in survival was found (93.6% after pediatric hip...

    Mohan, Arya J; Sekhar, Vini C; Bhaskar, Thallada; Nampoothiri, K Madhavan

    2016-08-01

    The efficacy of newly isolated Pseudomonas and Bacillus strains to degrade brominated High Impact Polystyrene (HIPS) was investigated. Viability of these cultures while using e-plastic as sole carbon source was validated through Triphenyl Tetrazolium Chloride (TTC). Four days incubation of HIPS emulsion with Bacillus spp. showed 94% reduction in turbidity and was 97% with Pseudomonas spp. Confirmation of degradation was concluded by HPLC, NMR, FTIR, TGA and weight loss analysis. NMR spectra of the degraded film revealed the formation of aliphatic carbon chain with bromine and its release. FTIR analysis of the samples showed a reduction in CH, CO and CN groups. Surface changes in the brominated HIPS film was visualized through SEM analysis. Degradation with Bacillus spp showed a weight loss of 23% (w/w) of HIPS film in 30days. PMID:26993201

  18. Epidemiology of hip fracture: Worldwide geographic variation

    Dinesh K Dhanwal

    2011-01-01

    Full Text Available Osteoporosis is a major health problem, especially in elderly populations, and is associated with fragility fractures at the hip, spine, and wrist. Hip fracture contributes to both morbidity and mortality in the elderly. The demographics of world populations are set to change, with more elderly living in developing countries, and it has been estimated that by 2050 half of hip fractures will occur in Asia. This review conducted using the PubMed database describes the incidence of hip fracture in different regions of the world and discusses the possible causes of this wide geographic variation. The analysis of data from different studies show a wide geographic variation across the world, with higher hip fracture incidence reported from industrialized countries as compared to developing countries. The highest hip fracture rates are seen in North Europe and the US and lowest in Latin America and Africa. Asian countries such as Kuwait, Iran, China, and Hong Kong show intermediate hip fracture rates. There is also a north-south gradient seen in European studies, and more fractures are seen in the north of the US than in the south. The factors responsible of this variation are population demographics (with more elderly living in countries with higher incidence rates and the influence of ethnicity, latitude, and environmental factors. The understanding of this changing geographic variation will help policy makers to develop strategies to reduce the burden of hip fractures in developing countries such as India, which will face the brunt of this problem over the coming decades.

  19. Osteoarthritis of the hip and acetabular dysplasia.

    Croft, P.; Cooper, C.; Wickham, C; Coggon, D

    1991-01-01

    The relation between acetabular dysplasia and osteoarthritis of the hip was examined in a series of 1516 pelvic radiographs taken for non-skeletal indications. Osteoarthritis was assessed by measuring joint space, and dysplasia by the centre-edge angle and acetabular depth. In contrast with previous studies of patients with symptomatic osteoarthritis of the hip, no evidence that dysplasia predisposes to osteoarthritis was found. Possible reasons for the discrepancy are discussed. It was concl...

    Albiñana, Javier; Gonzalez-Moran, Gaspar

    2002-01-01

    The dislocated hip in a non-ambulatory child with spastic paresis tends to be a painful interference to sleep, sitting upright, and perineal care. Proximal femoral resection-interposition arthroplasty is one method of treatment for this condition. We reviewed eight hips, two bilateral cases, with a mean follow-up of 30 months. Clinical improvement was observed in all except one case, with respect to pain relief and sitting tolerance. Some proximal migration was observed in three cases, despit...

  2. MR imaging of the hip

    Full text: MRI has been shown to gain increasing importance in recent years in the evaluation of disorders of the hip and pelvis. Nowadays, conventional or fast spin echo (T1, Turbo (Fast) T2 (or PD)) MR imaging sequences are used most commonly to examine the hip and pelvis. Three dimensional (3D) gradient echo (GE) imaging allows acquisition of very thin (1 mm) sections. MR imaging with fat suppression technique (STIR, TIRM, FAT SAT T2) represent an effective screening technique for the assessment of fluid, hemorrhage, pus, or tumor in the marrow, joint or soft tissues. These techniques increase the sensitivity for the detection of a variety of pathologic processes. Fat suppression MR imaging, when combined with intravenous (or intraarticular) administration of a gadolinium compound, also is effective and often is employed when evaluating neoplastic or infectious diseases (intravenous injection), abnormalities of articular cartilage or labrum, or possible intraarticular osteocartilaginous bodies (intraarticular injection). A lesion of the acetabular labrum based is one cause of chronic hip pain in patients with developmental dysplasia of the hips, as well as in patients with a history of hip trauma or femoroacetabular impingement. MR imaging and, in particular, MR arthrography, however, have been shown to be highly accurate in the detection of subtle intraarticular abnormalities such as labral lesion. Conventional MR imaging has shown poor accuracy in detecting labral lesions, due to its inability to depict small tears and the difficulty in determining if intralabral signal abnormalities extend to the surface of the labrum. MR arthrography, however has been shown to overcome these difficulties and to have excellent accuracy in detecting labral pathology. As labral abnormalities are believed to be a precursor of osteoarthritis, orthopedic surgeons believe that surgical intervention will be influenced substantially by the type, extension and location of labral

  3. Diagnosis of infection after total hip arthroplasty

    Forty-eight total hip arthroplasties for which revision surgery was performed were reviewed to determine the accuracy of laboratory tests, plain radiographs, hip aspiration, and technetium-99m MDP and gallium-67 scans in demonstrating the presence or absence of infection of the prosthesis. Six of the 48 hips were diagnosed as having an infection at the revision surgery. The erythrocyte sedimentation rate and the C-reactive protein levels were significantly higher in the patients with infected prostheses. The difference in the white blood cell count was not significant. There was no significant relationship between the presence of infection and the severity of loosening and instability of the implants diagnosed by plain radiographs. The accuracy of hip aspiration in diagnosing the infection was 83%, with a sensitivity of 40% and a specificity of 92%. The accuracy of technetium-99m MDP bone scan was 79%, with a sensitivity of 83%, and a specificity of 79%. Gallium-67 scan had an accuracy of 96%, a sensitivity of 67%, and a specificity of 100%. The findings in the present study indicated that diagnostic tests consisting of laboratory tests and plain radiography, followed by hip aspiration and sequential use of technetium-99m MDP and gallium-67 scintigraphies, are suitable for differentiation between mechanical loosening and infection of total hip arthroplasty.

  6. Hip Reconstruction Osteotomy by Ilizarov Method as a Salvage Option for Abnormal Hip Joints

    Masood Umer

    2014-01-01

    Full Text Available Hip joint instability can be secondary to congenital hip pathologies like developmental dysplasia (DDH or acquired such as sequel of infective or neoplastic process. An unstable hip is usually associated with loss of bone from the proximal femur, proximal migration of the femur, lower-extremity length discrepancy, abnormal gait, and pain. In this case series of 37 patients coming to our institution between May 2005 and December 2011, we report our results in treatment of unstable hip joint by hip reconstruction osteotomy using the Ilizarov method and apparatus. This includes an acute valgus and extension osteotomy of the proximal femur combined with gradual varus and distraction (if required for realignment and lengthening at a second, more distal, femoral osteotomy. 18 males and 19 females participated in the study. There were 17 patients with DDH, 12 with sequelae of septic arthritis, 2 with tuberculous arthritis, 4 with posttraumatic arthritis, and 2 with focal proximal femoral deficiency. Outcomes were evaluated by using Harris Hip Scoring system. At the mean follow-up of 37 months, Harris Hip Score had significantly improved in all patients. To conclude, illizarov hip reconstruction can successfully improve Trendelenburg’s gait. It supports the pelvis and simultaneously restores knee alignment and corrects lower-extremity length discrepancy (LLD.

    2015-01-01

    Objective: To investigate the percentage of ideal patients who would be eligible for hip-resurfacing surgery at a reference service for hip arthroplasty. Methods: Out of all the cases of hip arthroplasty operated at Hospital do Servidor Público Estadual de São Paulo (HSPE) between January 2009 and December 2010, we assessed a total of 592 procedures that would fit the criteria for indication for resurfacing arthroplasty, after clinical and radiological evaluation according to the criteria established by the Food and Drug Administration (FDA) and by Seyler et al. Results: Among the total number of hip replacement arthroplasty cases, 5.74% of the patients were eligible. Among the patients who underwent primary arthroplasty, we found that 8.23% presented ideal conditions for this procedure. Conclusion: The study demonstrated that this type of surgery still has a limited role among hip surgery methods. PMID:27047851

    Cankaya, Deniz; Aydin, Cemal; Karakus, Dilek; Toprak, Ali; Ozkurt, Bulent; Tabak, Yalçın

    2015-09-01

    We investigated the isokinetic performance of hip muscles and clinical outcomes after revision total hip arthroplasty (THA) via same anterolateral approach used in primary surgery. Thirty patients who had undergone previous THA via an anterolateral approach underwent both acetabular and femoral component revision after aseptic loosening. The Harris Hip Score (HHS) was evaluated during a minimum 2-year follow-up. The isokinetic muscle strength of the operated and nonoperated hips was assessed 1 year after surgery. The HHS improved from 49.0 to 77.4. Operated and nonoperated hips exhibited similar isokinetic performance during all measurements (flexion, extension, and abduction) (p>0.05). This prospective study showed that the anterolateral approach preserves abductor strength after revision THA in aseptic cases with acceptable functional and clinical results. The main clinical relevance of this study is that the same anterolateral approach used in previous primary THA is also safe and viable for revision THA. PMID:26435233

  11. Magnetic resonance imaging of hip joint cartilage and labrum

    Christoph Zilkens

    2011-09-01

    Full Text Available Hip joint instability and impingement are the most common biomechanical risk factors that put the hip joint at risk to develop premature osteoarthritis. Several surgical procedures like periacetabular osteotomy for hip dysplasia or hip arthroscopy or safe surgical hip dislocation for femoroacetabular impingement aim at restoring the hip anatomy. However, the success of joint preserving surgical procedures is limited by the amount of pre-existing cartilage damage. Biochemically sensitive MRI techniques like delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC might help to monitor the effect of surgical or non-surgical procedures in the effort to halt or even reverse joint damage.

  12. Arthroscopic management of an intraarticular osteochondroma of the hip

    Brian T. Feeley

    2009-04-01

    Full Text Available The role of hip arthroscopy in the management of femoroacetabular impingement (FAI has been advancing rapidly. In this case report, we describe the use of hip arthroscopy to successfully treat a femoral neck osteochondroma that caused a symptomatic labral tear in a 37 year old woman. Hip arthroscopy offers several advantages to surgical dislocation of the hip in the management of intra articular pathology and FAI. Hip arthroscopy is minimally invasive without the significant trauma to hip musculature, is useful in treatment of labral tears generated by FAI, and can be used to resect small lesions on the femoral head.

  13. MR arthrography of the hip joint

    MR arthrography of the hip joint is usually performed after a conventional MRI has been obtained to rule out other pathologies of the hip joint as for instance bone marrow edema or osteonecrosis of the hip. MR arthrography is mainly performed as a very special investigation, and it is executed in most cases if the clinician asks for the diagnosis of a labral lesion. In very rare cases, MR arthrography of the hip is performed to image cartilage disease or osteochondrosis dissecans or free intraarticular bodies. In this paper, the indications, the technique, and the most important pathology of the hip joint - labral lesions - will be described as well as variants of the normal acetabular labrum. After a conventional MRI of the hip joint has been performed, a MR arthrography of the hip will be obtained to search for labral pathology or cartilage disease. MR arthrography is obtained after the intraarticular injection of 10-20 ml of a 0.1 mmol solution of gadopentate-dimeglumine has been performed. The intraarticular injection can either be fluoroscopic-guided or CT-guided or directly MR-guided. After the intraarticular injection, MR arthrography will be performed by the use of paracoronal and parasagittal T1-weighted spin echo or gradient echo sequences. In cases of labral lesions (degeneration, labral tear, labral detachment) or cartilage disease MR arthrography proved to be more sensitive as conventional MRI as shown in the literature. The sensitivity of MRI to detect labral pathology was reported to be about 65%, and that of MR arthrography was reported to be about 92-95% compared to surgical results. According to the current literature, MR arthrography is the most sensitive method to delineate these kind of pathologies. Therefore, the invasive technique of MR arthrography may be justified for the correct diagnosis of these kind of pathologies after other pathologic entities have been ruled out by conventional MRI.

    2014-04-01

    Full Text Available Objective: To analyze the extent of postoperative hip abductor insufficiency in primary total hip arthroplasty (THA patients undergoing anterolateral minimally invasive (ALMI approach, and to investigate whether the clinical outcomes are more favorable in femoral neck fracture (FNF patients than in non-femoral neck fracture (nFNF patients. Methods:A total of 48 patients were enrolled in this study. Each patient underwent a clinical examination preoperatively and 6, 12, 24 and 48 weeks postoperatively. The abductor torque, Trendelenburg's sign, gait velocity, Harris hip score, Oxford hip score, Westren Ontario and McMaster Universities (WOMAC score and visual analog scale pain score were recorded. Statistical evaluation was performed with SPSS software version 18.0. The significance level was set at P<0.05. Results:The abductor torque of the operated hip and the recovery ratio showed a gradual improving tendency from 6 weeks postoperatively until the last follow-up. Gait velocity, Harris hip score, Oxford hip score and WOMAC score improved significantly after the operation until 24 weeks postoperatively. In the FNF group, the abductor torque of the operated side and the recovery ratio were significantly higher than in nFNF group at 6 weeks postoperatively, however, as time passed, this trend tended to disappear. Conclusion:This study demonstrates that patients can obtain good abductor strength and function in the early postoperative period and the hip abductor function of patients who suffer from hip osteoarthritis, rheumatoid arthritis, avascular necrosis of the femoral head could be significantly improved following ALMI THA.

    2014-01-01

    Background The acetabular teardrop is often used to guide acetabular component placement in total hip arthroplasty (THA).Placing the lower acetabular component aspect at the same level as the lower teardrop edge was assumed to restore the hip center of rotation.Here we radiographically analyzed the relationship between cup center and normal contralateral acetabulum center height on unilateral THA using this placement method.Methods A total of 106 unilateral THA cases with normal contralateral acetabula were reviewed and the vertical and horizontal distances in relation to the lower acetabular teardrop edge from both hip joint centers,cup inclination,and anteversion were measured radiographically.The paired t-test was used to compare left and right hip center heights.Scatter plots and Pearson's correlation coefficients were used to evaluate differences in hip center heights,cup anteversion,inclination angles,and medialized cup center distance compared to the contralateral hip joint.Results Cup center height was significantly greater (P <0.01) than contralateral hip joint center height (93.4% in the 0-5 mm range,6.6% >5 mm).There was a weak correlation between hip center height difference and inclination (r=0.376,P <0.01) and between difference and anteversion (r=0.310,P <0.01) but no correlation between difference and outer cup diameter (r=0.184,P=0.058) or difference and medialized cup center distance (r=-0.098,P=0.318).Conclusions Although this method did not exactly replicate anatomic hip center height,the clinical significance of cup center height and anatomic hip center height differences is negligible.This acetabular component placement method has high simplicity,reliability,and stability.

    Soares dos Santos, Marco P; Ferreira, Jorge A F; Ramos, A; Simões, José A O; Morais, Raul; Silva, Nuno M; Santos, Paulo M; Reis, M J C S; Oliveira, T

    Instrumented hip implants were proposed as a method to monitor and predict the biomechanical and thermal environment surrounding such implants. Nowadays, they are being developed as active implants with the ability to prevent failures by loosening. The generation of electric energy to power active mechanisms of instrumented hip implants remains a question. Instrumented implants cannot be implemented without effective electric power systems. This paper surveys the power supply systems of seventeen implant architectures already implanted in-vivo, namely from instrumented hip joint replacements and instrumented fracture stabilizers. Only inductive power links and batteries were used in-vivo to power the implants. The energy harvesting systems, which were already designed to power instrumented hip implants, were also analyzed focusing their potential to overcome the disadvantages of both inductive-based and battery-based power supply systems. From comparative and critical analyses of the methods to power instrumented implants, one can conclude that: inductive powering and batteries constrain the full operation of instrumented implants; motion-driven electromagnetic energy harvesting is a promising method to power instrumented passive and active hip implants.

  18. Screening for congenital dislocation of the hip

    Although the prevalence of (idiopathic) congenital dislocation of the hip (CDH) within the Member States of the European Community is not exactly known, it must be considered as a major problem of public health care and protection. By assessment of available data one can assume that between 1 and 2% of all newborns have dislocation or instability of one or both hips. There is a female predominance of 4:1 and some risk factors are known. The reasons of a higher prevalence in some areas are not yet well understood. Most of instable hips will spontaneously become stable within the first days or weeks of life. However, a considerable number of infants (less than 1%) will remain with instable hips which may dislocate. Dislocation either present at birth or as a result of persistent instability leads to subsequent hip deformation. This is a serious event for each affected individual, and is a heavy load on health care and social costs for the public. Treatment of CDH is easy and usually effective when started early, i.e. before the fourth month of life. The earlier treatment is started the easier, shorter, safer and less expensive it is and its impairment on child development and mother-child interaction can be held to a minimum. Screening for CDH is therefore the most important part of health protection in early infancy. However, this paper concludes that neither sonography nor X-ray examinations are appropriate for CDH screening

    The benefit of HIP techniques applied to the fabrication of fusion internal components for higher performances, reliability and cost savings are emphasized. To demonstrate the potential of the techniques, design of new blankets concepts and mock-ups fabrication are currently performed by CEA. A coiled tube concept that allows cooling arrangement flexibility, strong reduction of the machining and number of welds is proposed for ITER IAM. Medium size mock-ups according to the WCLL breeding blanket concept have been manufactured. The fabrication of a large size mock-up is under progress. These activities are supported by numerical calculations to predict the deformations of the parts during HIP'ing. Finally, several HIP techniques issues have been identified and are discussed

    We have reviewed more than a decade of clinical-echographical research in the developmental displasia of the hip (D.D.H.). We have examined 2050 small patients aged less than three months, with normal hips, and evaluated a number of ultrasound parameters that, in our opinion, may be helpful to give a description of hips particularly precise. We clearly underline that a precise definition, as more as possible, is a starting point to study all the pathological hips. PMID:15070268

    Full Text Available CONTEXT: Rehabilitation following hip arthroscopy is an integral component of the clinical outcome of the procedure. Given the increase in quantity, complexity, and diversity of procedures performed, a need exists to define the role of rehabilitation following hip arthroscopy.OBJECTIVES: 1 To determine the current rehabilitation protocols utilized following hip arthroscopy in the current literature, 2 to determine if clinical outcomes are significantly different based on different post-operative rehabilitation protocols; and 3 to propose the best-available evidence-based rehabilitation program following hip arthroscopy.DATA SOURCES: Per PRISMA guidelines and checklist, Medline, SciVerse Scopus, SportDiscus, and Cochrane Central Register of Controlled Trials were searched.STUDY SELECTION: Level I-IV evidence clinical studies with minimum two-year follow-up reporting outcomes of hip arthroscopy with post-operative rehabilitation protocols described were included. DATA EXTRACTION: All study, subject, and surgery parameters were collected. All elements of rehabilitation were extracted and analyzed. Descriptive statistics were calculated. Study methodological quality was analyzed using the Modified Coleman Methodology Score (MCMS.RESULTS: 18 studies were included (2,092 subjects; 52% male, mean age 35.1 +/- 10.6 years, mean follow-up 3.2 +/- 1.0 years. Labral tear and femoroacetabular impingement were the most common diagnoses treated and labral debridement and femoral/acetabular osteochondroplasty the most common surgical techniques performed. Rehabilitation protocol parameters (weight-bearing, motion, strengthening, and return-to-sport were poorly reported. Differences in clinical outcomes were unable to be assessed given heterogeneity in study reporting. Time-, phase-, goal-, and precaution-based guidelines were extracted and reported.CONCLUSIONS: The current literature of hip arthroscopy rehabilitation lacks high-quality evidence to support a

  18. Persistently High Hip Circumference after Bariatric Surgery Is a Major Hurdle to Successful Hip Replacement

    Menachem M. Meller; Courville, Amber B; Sumner, Anne E.

    2014-01-01

    The prevalence of class III obesity (BMI ≥ 40 kg/m2) in black women is 18%. As class III obesity leads to hip joint deterioration, black women frequently present for orthopedic care. Weight loss associated with bariatric surgery should lead to enhanced success of hip replacements. However, we present a case of a black woman who underwent Roux-en-Y gastric bypass with the expectation that weight loss would make her a better surgical candidate for hip replacement. Her gastric bypass was success...

    2011-01-01

    Full Text Available Children affected by mucopolysaccharidosis (MPS type IH (Hurler Syndrome, an autosomal recessive metabolic disorder, are known to experience a range of musculoskeletal manifestations including spinal abnormalities, hand abnormalities, generalised joint stiffness, genu valgum, and hip dysplasia and avascular necrosis. Enzyme therapy, in the form of bone marrow transplantation, significantly increases life expectancy but does not prevent the development of the associated musculoskeletal disorders. We present the case of a 23-year-old woman with a diagnosis of Hurler syndrome with a satisfactory result following uncemented total hip arthroplasty.

  2. Vaginal mass following uncemented total hip arthroplasty

    Young-Soo Shin

    2014-01-01

    Full Text Available A 53-year-old woman developed a vaginal mass following an uncemented total hip arthroplasty. The mass was in direct communication with the hip through an acetabular medial wall defect after loosening of the acetabular component. The mass formation was caused simultaneously by changes secondary to polyethylene wear, a tiny delamination of the porous titanium mesh coating and a broken antirotational tab on the acetabular cup, all of which may have served as sources of metal particles. A careful evaluation of the patient′s history, symptoms, X-ray findings and computed tomography scans should always be performed to ensure accurate diagnosis.

  4. Vascular injuries during total hip revision

    Although most patients undergoing a revision total hip replacement (THR) will have an uneventful procedure, in others the potential of serous vascular injuries is real. Migrating prosthesis or excessive cement may be in compromising positions adjacent or adherent to vessels and pose a particular danger at surgery with inadvertent lacerations of vessels such as the internal and external iliac arteries. In out study of 20 patients with THR, CT with two-dimensional reconstructions is used to define vessel position. In eight of these patients, the hip prosthesis or displaced cement lies within 5 mm of major vessels. In patients with dislocation of the acetabular cup, the potential of vascular injury is highest

  5. Hip pain is more frequent in severe hip displacement: a population-based study of 77 children with cerebral palsy.

    Ramstad, Kjersti; Terjesen, Terje

    2016-05-01

    The aim of this study was to assess whether hip pain was associated with radiographic hip displacement (migration percentage, MP) in a population-based cohort of children with cerebral palsy. Seventy-seven children, mean age 9.5 (SD 1.6) years and Gross Motor Function Classification System level III-V, were assessed. Caregivers responded to the Child Health Questionnaire pain questions and located recurrent pain on a body map. Hip pain was reported in 22 children (29%) and 27 hips (18%). Hip pain was significantly more frequent in hips with MP more than or equal to 50%, in children with spastic quadriplegia, and in those with Gross Motor Function Classification System level V. We conclude that severe hip displacement with MP more than or equal to 50% was associated with hip pain, whereas slight or moderate subluxation did not influence the occurrence of such pain.

    2014-01-01

    There is a high rate of mortality in elderly patients who sustain a fracture of the hip. We aimed to determine the rate of preventable mortality and errors during the management of these patients. A 12 month prospective study was performed on patients aged > 65 years who had sustained a fracture of the hip. This was conducted at a Level 1 Trauma Centre with no orthogeriatric service. A multidisciplinary review of the medical records by four specialists was performed to analyse errors of management and elements of preventable mortality. During 2011, there were 437 patients aged > 65 years admitted with a fracture of the hip (85 years (66 to 99)) and 20 died while in hospital (86.3 years (67 to 96)). A total of 152 errors were identified in the 80 individual reviews of the 20 deaths. A total of 99 errors (65%) were thought to have at least a moderate effect on death; 45 reviews considering death (57%) were thought to have potentially been preventable. Agreement between the panel of reviewers on the preventability of death was fair. A larger-scale assessment of preventable mortality in elderly patients who sustain a fracture of the hip is required. Multidisciplinary review panels could be considered as part of the quality assurance process in the management of these patients. Cite this article: Bone Joint J 2014;96-B:1178–84. PMID:25183587

    BACKGROUND Pain associated with coxarthrosis, typically occurring in middle-aged and elderly patients, very commonly causes considerable limitation of motor fitness and dependence on pharmacotherapy. This article provides an assessment of a rehabilitation program with tailored water exercises in patients with osteoarthritis before and after total hip replacement. MATERIAL AND METHODS A total of 192 patients (the mean age 61.03±10.89) suffering from hip osteoarthritis (OA) were evaluated before and after total hip replacement (THR). The clinical study covered measurements of hip active ranges of motion (HAROM) and the forces generated by pelvis stabilizer muscles. Pain intensity was assessed according to analogue-visual scale of pain (VAS) and according to the Modified Laitinen Questionnaire. The patients were divided into 6 groups (4 treatment and 2 control). We compared 2 rehabilitation programs using kinesitherapy and low-frequency magnetic field. One of them also had specially designed exercises in the water. Statistical analysis was carried out at the significance level α=0.05. This was a cross-sectional study. RESULTS A positive effect of water exercises on a number of parameters was found in patients with OA both before and after total hip replacement surgery. We noted a significant reduction of pain (pwater exercises most significantly reduced pain in patients with OA before and after total hip replacement surgery. 2. Inclusion of water exercises in a rehabilitation program can reduce the use of medicines in patient with OA and after THR. PMID:27455419

    PURPOSE: To investigate the effect on hip-flexion strength of a 6-week hip-flexor training programme using elastic bands as resistance. We hypothesized that the training group, compared to a control group, would increase their hip-flexion strength more. METHODS: Thirty-three healthy subjects (45...... % females), 24(5) years of age, were included in a randomized controlled trial and allocated to heavy strength training of the hip-flexor muscles or to control (no strength training). Strength training of the hip-flexors (dominant leg) was performed three times 10 min per week for 6 weeks. The strength...... training group progressed from 15 repetition maximum (RM) (week 1) to 8 RM (week 6). Isometric hip-flexion strength (primary outcome) was measured by a blinded assessor using a reliable test procedure. RESULTS: In the strength training group, the isometric hip-flexion strength of the trained leg increased...

    Hip fracture is one of the most common injuries among the elderly and, because the population is aging, it is expected to remain a major clinical challenge and public health problem for the foreseeable future. The clinical importance of early mobilization and prompt participation in physical therapy after hip fracture surgery is now widely recognized. Because postoperative pain can impair mobility and delay physical therapy, much attention is now being paid to finding more effective ways of controlling pain after hip fracture. Oversedation with opioid drugs inhibits communication between the patient and the health care team, can delay ambulation and rehabilitation therapy, and may increase the probability of the patient requiring a skilled nursing facility, which adds further cost to the overall health care system. Multiple pain pathways contribute to the perception of postoperative pain, and although opioids are highly effective in blocking nociceptive pain through inhibition of the mu receptors, they do not block other pain pathways. Multimodal analgesia involves the use of several anesthetic and analgesic modalities that are strategically combined to block pain perception at different sites in the peripheral and central nervous systems. This balanced, multifaceted approach provides more effective control of postoperative pain than opioid drugs alone, allows lower doses of opioids to be used as part of the multimodal regimen (thereby reducing the risk of opioid-related adverse events and complications), and may facilitate more rapid recovery and improve certain outcome measures related to recovery time. One prospective randomized study evaluating the clinical value of multimodal pain management in elderly patients undergoing bipolar hip hemiarthroplasty found that a multimodal regimen, including preemptive pain medication and intraoperative periarticular injections, reduced pain on postoperative days 1 and 4, and reduced overall opioid use.

  3. Greater Hip Extension but Not Hip Abduction Explosive Strength Is Associated With Lesser Hip Adduction and Knee Valgus Motion During a Single-Leg Jump-Cut

    Cronin, Baker; Johnson, Samuel T; Chang, Eunwook; Pollard, Christine D.; Norcross, Marc F.

    2016-01-01

    Background: The relationships between hip abductor and extensor strength and frontal plane hip and knee motions that are associated with anterior cruciate ligament injury risk are equivocal. However, previous research on these relationships has evaluated relatively low-level movement tasks and peak torque rather than a time-critical strength measure such as the rate of torque development (RTD). Hypothesis: Females with greater hip abduction and extension RTD would exhibit lesser frontal plane...

  5. Theoretical and practical aspects in total uncemented hip arthroplasty by using short femoral stem prosthesis

    Moga, M; Pogarasteanu, ME; Barbilian, A

    2015-01-01

    Hip arthrosis, primary or secondary, is an osteoarthritic degenerative process that affects the hip joint. Primary hip arthrosis has an unknown etiology, and secondary hip arthrosis has well defined causes; of these causes, some are known to lead to arthrosis of the hip in the young age patient. The surgical treatment aims either to preserve the patient’s hip joint, or to replace the joint. The most commonly used procedure at this time is the total hip arthroplasty. The femoral component may ...

  6. Greater Hip Extension but Not Hip Abduction Explosive Strength Is Associated With Lesser Hip Adduction and Knee Valgus Motion During a Single-Leg Jump-Cut

    Cronin, Baker; Johnson, Samuel T.; Chang, Eunwook; Pollard, Christine D.; Norcross, Marc F.

    2016-01-01

    Background: The relationships between hip abductor and extensor strength and frontal plane hip and knee motions that are associated with anterior cruciate ligament injury risk are equivocal. However, previous research on these relationships has evaluated relatively low-level movement tasks and peak torque rather than a time-critical strength measure such as the rate of torque development (RTD). Hypothesis: Females with greater hip abduction and extension RTD would exhibit lesser frontal plane hip and knee motion during a single-leg jump-cutting task. Study Design: Descriptive laboratory study. Methods: Forty recreationally active females performed maximal isometric contractions and single-leg jump-cuts. From recorded torque data, hip extension and abduction RTD was calculated from torque onset to 200 ms after onset. Three-dimensional motion analysis was used to quantify frontal plane hip and knee kinematics during the movement task. For each RTD measure, jump-cut biomechanics were compared between participants in the highest (high) and lowest (low) RTD tertiles. Results: No differences in frontal plane hip and knee kinematics were identified between high and low hip abduction RTD groups. However, those in the high hip extension RTD group exhibited lower hip adduction (high, 3.8° ± 3.0°; low, 6.5° ± 3.0°; P = .019) and knee valgus (high, –2.5° ± 2.3°; low, –4.4° ± 3.2°; P = .046) displacements during the jump-cut. Conclusion: In movements such as cutting that are performed with the hip in a relatively abducted and flexed position, the ability of the gluteus medius to control hip adduction may be compromised. However, the gluteus maximus, functioning as a hip abductor, may take on a pivotal role in controlling hip adduction and knee valgus motion during these types of tasks. Clinical Relevance: Training with a specific emphasis on increasing explosive strength of the hip extensors may be a means through which to improve frontal plane hip and knee

  7. HIP10680/HIP10679: a visual binary in the $\\beta$ Pictoris Association with the fastest rotating member

    Messina, Sergio; Zambelli, Roberto

    2015-01-01

    We present the results of a multi-filter photometric monitoring of the wide binary HIP10680/HIP10679. We found both component to be variable with amplitude up to $\\Delta$V = 0.03 mag in the case of HIP10680 and $\\Delta$V = 0.07 mag in the case of HIP10679. We could measure the rotation periods P = 0.2396d of the hotter F5V component HIP10680 and P = 0.777d of the cooler G5V component HIP10679. We found that the rotation axes of both components are aligned with an inclination $i$ = $\\sim$ 10$^{\\circ}$. Although the two components have a mass difference not larger than 15%, they exhibit a significant difference between their rotation periods. Such difference may arise either from different initial rotation periods or to different disc life times. For instance, the slower rotating component HIP 10679 hosts a well know debris disc.

  8. The Hip Lag Sign--prospective blinded trial of a new clinical sign to predict hip abductor damage.

    Alexander Kaltenborn

    Full Text Available This study introduces and validates the Hip Lag Sign, a new clinical parameter to determine hip abductor damage, which appears to be one major cause for greater trochanteric pain syndrome. 26 patients who underwent standardized MRI-examination were prospectively enrolledbetween October 2009 and March 2012. A standard physical examination of the hip was performed, including the Hip Lag Sign as it is defined for the first time in this work. Hip Lag Sign results were statistically compared toMR images, to pain levels measured with the visual analogue scale and to results of the modified Harris Hip Score as a universal and well established diagnostic tool for the hip. Chi2- and Mann-Whitney-U-analysis were applied. Diagnostic accuracy was tested with 2×2-table-calculations.Kappa statistics were used to analyze inter-observer variability. A positive Hip Lag Sign is significantly associated with MRI-proven hip abductor damage (p<0.001. The Hip Lag Sign has a sensitivity of 89.47% and a specificity of 96.55%. The positive and negative predictive values are 94.44%, resp. 93.33%. Its diagnostic Odds Ratio is 239.000 (p<0.001; 95%-CI: 20.031-2827.819. The number needed to diagnose was 1.16.Inter-observer consistency was 98.1% and kappa statistics for inter-observer variability were 0.911. The Hip Lag Sign is specific and sensitive, easy and fast to perform and allows a reliable assessment on the hip abductors' status, especially when there is no access to further diagnostic devices such as MRI for example due to restricted resources like in developing countries. Thus, we recommend the inclusion of the Hip Lag Sign into everyday hip examinations, especially dealing with patients suffering from greater trochanteric pain syndrome.

    The appearance and distribution of the intra-articular plicae of the hip have been addressed in few reports in the anatomic and radiological literature. This study aims to determine the prevalence of visible synovial hip plicae using MR arthrography and to measure the association of visible synovial hip plicae with MR arthrographic diagnosis of labral tears, femoroacetabular impingement, and osteoarthritis. Following institutional review board approval, 63 direct MR arthrographic examinations of the hip in 61 patients with a clinical history of hip pain were retrospectively reviewed by two experienced musculoskeletal radiologists in consensus. The following variables were measured using a binary system (0 = absent; 1 = present): labral plica, neck plica, ligamental plica, labral tear, femoroacetabular impingement, and osteoarthritis. The surgical reports and arthroscopic images of 10 patients were reviewed. Statistical analysis was performed using the Fisher's exact test. In all 63 cases at least one plica was visualized on MR-arthrographic images. Labral, neck, and ligamental plicae were found with a prevalence of 76, 97, and 78%, respectively. There was no statistically significant association between the presence of labral tears, femoroacetabular impingement, and osteoarthritis among patients with visible labral, neck, and ligamental plicae. The prevalence of labral tears, femoroacetabular impingement, and osteoarthritis in our patient population was 79, 28, and 28%, respectively. The presence of intra-articular plicae was the only MR-arthrographic finding in 5 of our 63 symptomatic cases. Visible labral, neck, and/or ligamental plicae are highly prevalent on MR-arthrographic images of the hip performed in the setting of hip pain. There was no statistically significant association between the presence of labral tears, femoroacetabular impingement, and osteoarthritis and visible labral, neck, and ligamental plicae. (orig.)

    2008-06-15

    To evaluate the CT images of reduced hips after posterior hip dislocation and to propose specific diagnostic criteria based on the CT results. We retrospectively reviewed the CT findings on 18 reduced hips from 17 patients with radiographs and clinical histories of traumatic posterior hip dislocations by evaluating 18 corresponding CT scans for joint space asymmetry, intra-articular abnormalities (intra-articular fat obliteration, loose bodies, and joint effusion), changes in posterior soft tissue (capsule, muscles, and adjacent fat), the presence, and location of fractures (acetabulum and femoral head). All 18 hips (100%) showed posterior soft tissue changes. In total, 17 hips (94.4%) had intra-articular abnormalities and 15 hips (83.3%) had joint space asymmetries. In addition, 17 hips (94.4%) had fractures involving the acetabula (15 cases, 88.2%) the femoral head (13 cases, 76.5%), or on both sides (11 cases, 64.7%). The most frequent fracture location was in he posterior wall (13/15, 86.7%) of the acetabulum and in the anterior aspect (10/13, 76.9%) of the femoral head. Patients with a prior history of posterior hip dislocation showed specific CT findings after reduction, suggesting the possibility of previous posterior hip dislocations in patients.

  12. Differential diagnosis of pain around the hip joint.

    Tibor, Lisa M; Sekiya, Jon K

    2008-12-01

    The differential diagnosis of hip pain is broad and includes intra-articular pathology, extra-articular pathology, and mimickers, including the joints of the pelvic ring. With the current advancements in hip arthroscopy, more patients are being evaluated for hip pain. In recent years, our understanding of the functional anatomy around the hip has improved. In addition, because of advancements in magnetic resonance imaging, the diagnosis of soft tissue causes of hip pain has improved. All of these advances have broadened the differential diagnosis of pain around the hip joint and improved the treatment of these problems. In this review, we discuss the causes of intra-articular hip pain that can be addressed arthroscopically: labral tears, loose bodies, femoroacetabular impingement, capsular laxity, tears of the ligamentum teres, and chondral damage. Extra-articular diagnoses that can be managed arthroscopically are also discussed, including: iliopsoas tendonitis, "internal" snapping hip, "external" snapping hip, iliotibial band and greater trochanteric bursitis, and gluteal tendon injury. Finally, we discuss extra-articular causes of hip pain that are often managed nonoperatively or in an open fashion: femoral neck stress fracture, adductor strain, piriformis syndrome, sacroiliac joint pain, athletic pubalgia, "sports hernia," "Gilmore's groin," and osteitis pubis.

  13. Hip and pelvis diseases on lumbar AP radiographs including both hip joints

    To determine the frequency of diseases of the hip and pelvis, as seen of plain radiography of the lumbar spine in patients with suspicious lumbar disease, and to evaluate the methods used of lumbar spine radiography in Korea. Sixty university and training hospitals were randomly selected and asked to describe the projections, film size and radiographic techniques employed for routine radiography in patients with suspected disease of the lumbar spine. Plain radiographs of 1252 patients, taken using 14' x 17' film and depicting both hip joints and the lumbar region, were analysed between March 1999 and February 2000. In 15 patients (1.2%), the radiographs revealed hip or pelvic lesions, confirmed as follows: avascular necrosis of the femoral head (n=11, with bilateral lesions in four cases); sustained ankylosing spondylitis (n=2); acetabular dysplasia (n=1); and insufficiency fracture of the pubic rami secondary to osteoporosis (n=1). In 11 of the 20 hospitals which responded, 14' x 17' film was being used for lumbar radiography, while in the other nine, film size was smaller. Plain radiography of the lumbar spine including both hip joints, may be a useful was to simultaneously evaluate lesions not only of the lumbar spine but also of the hip and/or pelvis

    Full Text Available The aim of this study was to assess the influence of bone mineral density and hip geometry on the fragility fracture of femoral neck and trochanteric region. There were 95 menopausal females of age ≥ 50 years with fragility fracture of hip, including 55 cases of femoral neck fracture and 40 cases of trochanteric fracture. Another 63 non-fractured females with normal bone mineral density (BMD were chosen as control. BMD, hip axis length, neck-shaft angle and structural parameters including cross surface area, cortical thickness and buckling ratio were detected and compared. Compared with control group, the patients with femoral neck fracture or trochanteric fractures had significantly lower BMD of femoral neck, as well as lower cross surface area and cortical thickness and higher buckling ratio in femoral neck and trochanteric region. There were no significant differences of BMD and structural parameters in the femoral neck fracture group and intertrochanteric fracture group. Hip axis length and neck-shaft angle were not significantly different among three groups. The significant changes of BMD and proximal femur geometry were present in the fragility fracture of femoral neck and trochanteric region. The different types of hip fractures cannot be explained by these changes.

  15. Cartilage restoration technique of the hip.

    Mardones, Rodrigo; Larrain, Catalina

    2016-04-01

    Hip cartilage lesions represent a diagnostic challenge and can be an elusive source of pain. Treatment may present difficulties due to localization and spherical form of the joint and is most commonly limited to excision, debridement, thermal chondroplasty and microfractures. This chapter will focus in new technologies to enhance the standard techniques. These new technologies are based in stem cells therapies; as intra-articular injections of expanded mesenchymal stem cells, mononuclear concentrate in a platelet-rich plasma matrix and expanded mesenchymal stem cells seeded in a collagen membrane. This review will discuss the bases, techniques and preliminary results obtained with the use of stem cells for the treatment of hip cartilage lesions. PMID:27026816

  16. An unusual pain in the hip

    Bangera, Sachin; Dunkow, Paul; Weerasinghe, Suboda; Murugesan, Senthil V.

    2016-01-01

    A 68-year-old previously healthy man presented with increasing right hip pain of 6 months duration. On examination he was found to have a hard mass in the right hip arising from the pelvic bone. Imaging studies were in keeping with a sarcoma arising from the right iliac bone. However, biopsy of this bony lesion confirmed this to be a metastatic adenocarcinoma rather than a primary bone malignancy. Further imaging and a subsequent colonoscopy revealed the primary to be a colonic adenocarcinoma. The unique and unusual nature of this case was the presentation as a solitary bony metastasis from a colonic primary. There is no previously documented report in the literature of such a rare presentation of a colonic adenocarcinoma as a solitary bony lesion mimicking a primary sarcoma in the absence of other signs or symptoms.

    Full Text Available Hip resurfacing technique is a conservative arthroplasty used in the young patient in which the femoral head is reshaped to accept metal cap with small guide stem. In the present investigation, a hybrid composite-metal resurfacing implant is proposed. The cup is made of carbon fiber/polyamide 12 (CF/PA12 covered with a thin layer of cobalt chrome (Co-Cr. Finite element (FE method was applied to analyze and compare the biomechanical performances of the hybrid hip resurfacing (HHR and the conventional Birmingham (BHR. Results of the finite element analysis showed that the composite implant leads to an increase in stresses in the cancellous bone by more than 15% than BHR, indicating a lower potential for stress shielding and bone fracture and higher potential for bone apposition with the HHR.

    2011-12-01

    Full Text Available Abstract Background A discrepancy in leg length and femoral offset restoration is the leading cause of patient dissatisfaction in hip replacement surgery and has profound implications on patient quality of life. The aim of this study is to compare biomechanical hip reconstruction in hip resurfacing, large-diameter femoral head hip arthroplasty and conventional total hip replacement. Method Sixty patient's post-operative radiographs were reviewed; 20 patients had a hip resurfacing (HR, 20 patients had a Large Head Metal-on-metal (LHM hip replacement and 20 patients had a conventional small head Total Hip Replacement (THR. The leg length and femoral offset of the operated and unoperated hips were measured and compared. Results Hip resurfacing accurately restored hip biomechanics with no statistical difference in leg length (P = 0.07 or femoral offset (P = 0.95 between the operated and non-operative hips. Overall HR was superior for reducing femoral offset discrepancies where it had the smallest bilateral difference (-0.2%, P = 0.9. The traditional total hip replacement was least effective at restoring the hip anatomy. Conclusion The use of a larger-diameter femoral head in hip resurfacing does not fully account for the superior biomechanical restoration, as LHM did not restore femoral offset as accurately. We conclude that restoration of normal hip biomechanics is best achieved with hip resurfacing.

    Hip arthroplasty has become a common and still increasing procedure for the treatment of osteoarthritis, advanced head necrosis, post-inflammatory arthritis or rheumatoid arthritis.Radiography is the most important imaging modality for monitoring the normal, asymptomatic hip arthroplasty. Radiographs are obtained at the end of a surgical treatment, to exclude complications like fracture or component misplacement. In the follow-up radiographs are used for the diagnosis of loosening and infection of the hip arthroplasty as well as soft tissue ossification. Together with the history and clinical information, the analysis of morphological findings allows to find the grade of loosening. MRI has been advocated in the diagnosis of infection, in particular in the localisation of soft tissue involvement.Imaging, especially by radiographs, is used for the evaluation of the normal and complicated follow-up of hip arthroplasty.

  5. Cementless isoelastic RM total hip prosthesis1

    Bombelli, Renato; Mathys, Robert

    1982-01-01

    Some surgeons are beginning to doubt the reliability of bone cement in joint replacements. In 1967 Robert Mathys conceived the idea of an isoelastic prosthesis made of plastic, which would anchor into the bone without cement. He developed the idea by extensive tests in animals and, in 1973, the first human RM cementless hip prosthesis was inserted by E Morscher. In this paper the concept of the cementless isoelastic prosthesis is developed by Robery Mathys, and Professor Bombelli records his ...

  6. Medical images of the hip joint

    Up-to date techniques of sectional imaging of selected planes and ultrasonic methods have contributed considerably to improved diagnostic accuracy in the identification of hip joint anomalies in infants. Even though these innovations deserve to be valued highly the more conventional diagnostic methods are far from being superfluous and continue to be used on a routine basis in radiology. The relevant methods of focussing and ranges of use for standard and special projections are therefore surveyed in the following. (orig./GDG)

  7. The anatomy of the hip abductor muscles.

    Flack, N A M S; Nicholson, H D; Woodley, S J

    2014-03-01

    The anatomy of the hip abductors has not been comprehensively examined, yet is important to understanding function and pathology in the gluteal region. For example, pathology of the hip abductor muscle-tendon complexes can cause greater trochanteric pain syndrome, and may be associated with gluteal atrophy and fatty infiltration. The purpose of this study was to investigate the detailed morphology of gluteus medius (GMed), gluteus minimus (GMin), and tensor fascia lata (TFL), and determine whether the muscles comprised anatomical compartments. The gluteal region from 12 cadavers was dissected and data collected on attachment sites, volume, fascicular and tendinous anatomy, and innervation. Three sites of GMed origin were identified (gluteal fossa, gluteal aponeurosis, and posteroinferior edge of the iliac crest) and the distal tendon had lateral and posterior parts. GMed was the largest in volume (27.6 ± 11.6 cm(3); GMin 14.1 ± 11.1 cm(3); TFL 1.8 ± 0.8 cm(3)). Fascicles of GMin originated from the gluteal fossa, inserting onto the deep surface of its distal tendon and the hip joint capsule. TFL was encapsulated in the fascia lata, having no bony attachment. Primary innervation patterns varied for GMed, with three or four branches supplying different regions of muscle. Distinct secondary nerve branches entered four regions of GMin; no differential innervation was observed for TFL. On the basis of architectural parameters and innervation, GMed, and GMin each comprise of four compartments but TFL is a homogenous muscle. It is anticipated that these data will be useful for future clinical and functional studies of the hip abductors. PMID:23625344

    One of the most important issues in the modern total hip arthroplasty (THA) is the bearing surface. Extensive research on bearing surfaces is being conducted to seek an ideal bearing surface for THA. The ideal bearing surface for THA should have superior wear characteristics and should be durable, bio-inert, cost-effective, and easy to implant. However, bearing surfaces that are currently being implemented do not completely fulfill these requirements, especially for young individuals for whom...

  9. Imaging of neuropathies about the hip

    Neuropathies about the hip may be cause of chronic pain and disability. In most cases, these conditions derive from mechanical or dynamic compression of a segment of a nerve within a narrow osteofibrous tunnel, an opening in a fibrous structure, or a passageway close to a ligament or a muscle. Although the evaluation of nerve disorders primarily relies on neurological examination and electrophysiology, diagnostic imaging is currently used as a complement to help define the site and aetiology of nerve compression and exclude other disease possibly underlying the patient’ symptoms. Diagnosis of entrapment neuropathies about the hip with US and MR imaging requires an in-depth knowledge of the normal imaging anatomy and awareness of the anatomic and pathologic factors that may predispose or cause a nerve injury. Accordingly, the aim of this article is to provide a comprehensive review of hip neuropathies with an emphasis on the relevant anatomy, aetiology, clinical presentation, and their imaging appearance. The lateral femoral cutaneous neuropathy (meiralgia paresthetica), femoral neuropathy, sciatic neuropathy, obturator neuropathy, superior and inferior gluteal neuropathies and pudendal neuropathy will be discussed

  10. Friction measurement in a hip wear simulator.

    Saikko, Vesa

    2016-05-01

    A torque measurement system was added to a widely used hip wear simulator, the biaxial rocking motion device. With the rotary transducer, the frictional torque about the drive axis of the biaxial rocking motion mechanism was measured. The principle of measuring the torque about the vertical axis above the prosthetic joint, used earlier in commercial biaxial rocking motion simulators, was shown to sense only a minor part of the total frictional torque. With the present method, the total frictional torque of the prosthetic hip was measured. This was shown to consist of the torques about the vertical axis above the joint and about the leaning axis. Femoral heads made from different materials were run against conventional and crosslinked polyethylene acetabular cups in serum lubrication. Regarding the femoral head material and the type of polyethylene, there were no categorical differences in frictional torque with the exception of zirconia heads, with which the lowest values were obtained. Diamond-like carbon coating of the CoCr femoral head did not reduce friction. The friction factor was found to always decrease with increasing load. High wear could increase the frictional torque by 75%. With the present system, friction can be continuously recorded during long wear tests, so the effect of wear on friction with different prosthetic hips can be evaluated. PMID:27160557

  12. Plastazote abduction orthosis in the management of neonatal hip instability.

    Eberle, Charles F

    2003-01-01

    Since 1987, 113 consecutive newborns with either Ortolani-positive or provocative-positive hip examinations in the newborn nursery have been treated with a Plastazote hip abduction orthosis when diagnosed and followed to determine if the method was safe, effective, and easy to use. Ortolani-positive hips often had bilateral abnormalities in the hip examination, were frequently associated with breech position, and were anatomically more dysplastic than those hips that were unstable by provocative testing. No patient developed ischemic necrosis during follow-up. Only two had additional treatment of their unstable hips. The rest had excellent results. Parents and caregivers found the device easy to use. The orthosis is recommended as the primary method for managing newborns with clinical instability to either the provocative or Ortolani test as being safe, effective, and easy to use across all skill levels.

    2014-01-01

    PURPOSE: Low eccentric strength of the hip abductors, might increase the risk of patellofemoral pain syndrome and iliotibial band syndrome in runners. No normative values for maximal eccentric hip abduction strength have been established. Therefore the purpose of this study was to establish...... normative values of maximal eccentric hip abduction strength in novice runners. METHODS: Novice healthy runners (n = 831) were recruited through advertisements at a hospital and a university. Maximal eccentric hip abduction strength was measured with a hand-held dynamometer. The demographic variables...... associated with maximal eccentric hip abduction strength from a univariate analysis were included in a multivariate linear regression model. Based on the results from the regression model, a regression equation for normative hip abduction strength is presented. RESULTS: A SIGNIFICANT DIFFERENCE IN MAXIMAL...

  14. Evaluation of Two Total Hip Bearing Materials for Resistance to Wear Using a Hip Simulator

    Kenneth R. St. John

    2015-06-01

    Full Text Available Electron beam crosslinked ultra high molecular weight polyethylene (UHMWPE 32 mm cups with cobalt alloy femoral heads were compared with gamma-irradiation sterilized 26 mm cups and zirconia ceramic heads in a hip wear simulator. The testing was performed for a total of ten million cycles with frequent stops for cleaning and measurement of mass losses due to wear. The results showed that the ceramic on UHMWPE bearing design exhibited higher early wear than the metal on highly crosslinked samples. Once a steady state wear rate was reached, the wear rates of the two types of hip bearing systems were similar with the ceramic on UHMPWE samples continuing to show a slightly higher rate of wear than the highly crosslinked samples. The wear rates of each of the tested systems appear to be consistent with the expectations for low rates of wear in improved hip replacement systems.

    2005-01-01

    Full Text Available Background: High rates of loosening of cemented implants led to change in technique of fixation of the implant. Methods: Fifty-nine hips were operated in 42 patients with non-cemented acetabular and cemented femoral components between January 1999 and July 2003. The average age of the patient was 45.2 years in our study. Preoperative diagnosis was avascular necrosis (28, ankylosing spondylitis (18, fracture neck femur (9, rheumatoid arthritis (2 and osteoarthritis (2. Results: At an average follow up of 3.6 years (range 1.2-5.8 years excellent to good results were obtained 92% according to Harris hip criteria. No radiological loosening was noted in any femoral or acetabular component on follow up. One poor result was seen in a case of bilateral ankylosing spondylitis operated on one side. Conclusion: Hybrid THA provides a viable and highly acceptable method of treatment of diseases of hip in young patients.

    2008-01-01

    The use of computer navigation during hip resurfacing has been proposed to reduce the risk of a malaligned component and notching with subsequent postoperative femoral neck fracture. Femoral component malalignment and notching have been identified as the major factors associated with femoral neck fracture after hip resurfacing. We performed 37 hip resurfacing procedures using an imageless computer navigation system. Preoperatively, we generated a patient-specific computer model of the proxima...

  19. Muscle mass and function after total hip arthroplasty

    Rasch, Anton

    2009-01-01

    Osteoarthritis (OA) of the hip is a common disease among elderly causing pain, joint stiffness and reduced mobility. Outcome studies have shown total hip arthroplasy (THA) to be a successful surgical procedure. Studies of muscle strength and function after THA are more scarce and results vary. It has been suggested that unloading of the OA limb due to pain, results in hip and thigh muscle weakness and atrophy causing an abnormal gait and impaired postural control. Muscle atr...

    A normally functioning hip joint is imperative for athletes who use their lower extremities with running, jumping, or kicking activities. Sports-related injuries of the hip and groin are far less frequent than injuries to the more distal aspect of the extremity, accounting for less than 10% of lower extremity injuries. Despite the lower incidence, hip and groin injuries can lead to significant clinical and diagnostic challenges related to the complex anatomy and biomechanical considerations o...

  4. Wear prediction of ceramic-on-ceramic hip artificial joints

    Askari, E; Flores, Paulo; Dabirrahmani, D.; Appleyard, R.

    2015-01-01

    Wear can influence the lifetime and performance of implants and has been found to be a key factor in primary failure of artificial hip joints. The present study aims to present a spatial multibody dynamic model to predict wear in ceramic-on-ceramic hip implants. The problem was formulated by developing a spatial multibody dynamic model of a hip prosthesis taking three-dimensional physiological loading and motion of the human body into account. Then, the Archard wear model was inte...

  5. The influence of heterotopic ossification on functional status of hip joint following total hip arthroplasty

    Purpose: The functional failure induced by heterotopic ossification (HO) following total hip arthroplasty (THA) was analyzed and correlated to the radiologic failure. Patients and methods: From July 1997 to July 2001, 315 patients (345 hips) received THA indicated by a hypertrophic osteoarthritis of higher degree (Kellgren grade III, IV). All patients were irradiated prophylactically for prevention of HO on the evening before surgery with a 7-Gy single fraction. The patients' median age was 66.3 years. Radiologic failure was assessed by comparison of pre- and postoperative hip X-rays (immediately and 6 months after surgery). Analysis of radiographs was performed according to the Brooker Score. Clinical failure was appraised by measurement of passive range of motion (ROM) of the hip joint with a standard goniometer. The t-test was used for statistical analysis. Results: 281 patients (81.5%) did not develop HO. HO of Brooker grade I or II was found in 58 patients (16.8%). Six patients (1.7%) developed HO Brooker grade III or IV. There was a significant negative correlation between the degree of radiologic and clinical failure. ROM differed significantly between patients with HO Brooker grade 0, I, II and patients with HO Brooker grade III, IV. Comparing the pre- and postoperative ROM, all patients with Brooker grade 0, I and II showed a significant improvement of flexion, internal and external rotation, abduction and adduction movement. Patients with HO Brooker grade III and IV showed no improvement of ROM in the postoperative follow-up. Conclusion: The development of HO following THA influences the physical function of the hip joint dependent on the degree of ossification. HO of lower degree (Brooker I, II) does not influence the clinical outcome, whereas HO of higher degree (Brooker III, IV) reduces the function of hip arthroplasty. Therefore, the purpose of a prophylactic therapy must be to reduce HO of higher degree. (orig.)

    Background Pain associated with coxarthrosis, typically occurring in middle-aged and elderly patients, very commonly causes considerable limitation of motor fitness and dependence on pharmacotherapy. This article provides an assessment of a rehabilitation program with tailored water exercises in patients with osteoarthritis before and after total hip replacement. Material/Methods A total of 192 patients (the mean age 61.03±10.89) suffering from hip osteoarthritis (OA) were evaluated before and after total hip replacement (THR). The clinical study covered measurements of hip active ranges of motion (HAROM) and the forces generated by pelvis stabilizer muscles. Pain intensity was assessed according to analogue-visual scale of pain (VAS) and according to the Modified Laitinen Questionnaire. The patients were divided into 6 groups (4 treatment and 2 control). We compared 2 rehabilitation programs using kinesitherapy and low-frequency magnetic field. One of them also had specially designed exercises in the water. Statistical analysis was carried out at the significance level α=0.05. This was a cross-sectional study. Results A positive effect of water exercises on a number of parameters was found in patients with OA both before and after total hip replacement surgery. We noted a significant reduction of pain (pdegree of degenerative deforming lesions and the effects of the treatment process (p<0.01). Conclusions 1. The rehabilitation program including water exercises most significantly reduced pain in patients with OA before and after total hip replacement surgery. 2. Inclusion of water exercises in a rehabilitation program can reduce the use of medicines in patient with OA and after THR. PMID:27455419

  7. Neurovascular lesion after total hip arthroplasty in congenital hip dysplasia: Case report

    Stojković-Jovanović Tatjana

    2013-01-01

    Full Text Available Introduction. Nowadays, the total hip arthroplasty is a very frequent surgical intervention. In some cases, vascular and nerve injuries may happen around the hip with total hip arthroplasty. Although they are very rare, they may be very dangerous for the patient in some cases. This paper presents a case of a female patient, in whom the nervous fibularis lesion was detected after the total hip arthroplasty, and the occlusion of the iliac femoral artery was revealed later during physical therapy. Case Report. We described a case of a 32-year-old female patient, in whom the nervous fibularis lesion was detected after the total hip arthroplasty. The patient was referred to a ward for physical therapy. On the 19th postoperative day, she felt a vigorous ache and numbness on the left operated leg during stimulation of the paretic fibular musculature. Clinically weak inguinal arterial pulse was detected. After the examination, iliac-femoral occlusion was diagnosed. The patient was referred to the vascular surgeon. In the next few months, she was treated conservatively and eventually underwent surgery. The revascularization was achieved with a satisfactory effect. A year after the total hip replacement, the patient continued with rehabilitation and physical treatment, which lasted one and a half month and had an incomplete functional result - the patient walked with a walking stick and had weak fibular musculature of a severe degree. The vascular status of the leg was good. Conclusion. In this case, neurovascular lesions led to an incomplete functional recovery of the patient and compromised the expected treatment outcome. According to the scoring system used to assess the functionality, the result was marked as poor.

  8. Results of hip resurfacing for developmental dysplasia of the hip of Crowe type Ⅰ and Ⅱ

    2008-01-01

    Background Recently, the new generation of metal-on-metal total hip resurfacing arthroplasty is well known for preserving the proximal femoral bone stock, minimizing the risk of postoperative dislocation using large femoral heads, and expecting low wear of metal-on-metal articulation for longer prosthesis survival. It also has the advantage in biomechanical loading in the proximal femur. The osteoarthritis secondary to developmental dysplasia of the hip (DDH) has been the most common reason for total hip arthroplasty. Most of the patients are young and active, who require improved range of motion of the hip besides relief of the pain, even expect to resume the ability to run and jump after the joint arthroplasty, thus to be allowed an active lifestyle. The objective of the current study was to evaluate the early outcome of resurfacing arthroplasty for the mild DDH cases (Crowe type Ⅰ and Ⅱ).Methods Between September 2005 and May 2007, twenty-one consecutive patients (twenty-six hips) with the diagnosis of osteoarthritis secondary to DDH underwent metal-on-metal resurfacing arthroplasty. The average age at the time of surgery was 46.5 years (range, 37-59 years). Six patients (28.6%) were male and fifteen (71.4%) were female. Clinical and radiographic results were observed. The follow-up was performed at 6 weeks, 3, 6, 9 months and then yearly.Results All patients were followed for a mean of 18 months (9-29 months). During the follow-up period no complications, such as dislocation of hip joints, infection or femoral neck fracture occurred. The clinical outcomes, as rated with the Harris hip score, improved significantly compared with the preoperative ratings. The mean postoperative Harris hip score was 90.7, compared to 35.5 preoperatively. The radiographic analysis showed that all prostheses were fixed with no radiolucencies. All of the patients who had equal limb lengths preoperatively had equal lengths postoperatively. Of the nine patients with preoperative

  9. MR findings of transient synovitis of the hip

    To evaluate the MR findings of transient synovitis of the hip in children. Between 1993 and 1997, MR imaging was performed in 30 children (male:female 22:8) in whom transient synovitis had been clinically diagnosed. In 20 of these 30 patients, Gd-enhanced study was also performed. The signal intensity of bone marrow of the femur, the synovial enhancement pattern and the amount of hip joint effusion in affected hips were evaluated; the last -mentioned was determined using the volume measurement method. In 29 patients (97%), no abnormal signal intensity was seen in bone marrow of the femur in affected hips. Gd-enhanced MR imaging revealed synovial enhancement of affected hip joints, as follows: minimal enhancement in eight patients (40%), moderate enhancement in eight (40%), and strong enhancement in four (20%). No abnormal enhancement was demonstrated in bone marrow of the femur or adjacent soft tissue. The mean amount of joint effusion of affected hips was 2.7±1.7 (range, 0.2-18.9)ml; statistically, this was much greater than that of contralateral hip (p less than 0.01). The MR findings of transient synovitis of the hip in children were normal bone marrow signal intensity of the femoral head, moderate or strong synovial enhancement, and asymmetric hip joint effusion.

  12. Characteristics of children with hip displacement in cerebral palsy

    Wagner Philippe

    2007-10-01

    Full Text Available Abstract Background Hip dislocation in children with cerebral palsy (CP is a common and severe problem. The dislocation can be avoided, by screening and preventive treatment of children with hips at risk. The aim of this study was to analyse the characteristics of children with CP who develop hip displacement, in order to optimise a hip surveillance programme. Methods In a total population of children with CP a standardised clinical and radiological follow-up of the hips was carried out as a part of a hip prevention programme. The present study is based on 212 children followed until 9–16 years of age. Results Of the 212 children, 38 (18% developed displacement with Migration Percentage (MP >40% and further 19 (9% MP between 33 and 39%. Mean age at first registration of hip displacement was 4 years, but some hips showed MP > 40% already at two years of age. The passive range of hip motion at the time of first registration of hip displacement did not differ significantly from the findings in hips without displacement. The risk of hip displacement varied according to CP-subtype, from 0% in children with pure ataxia to 79% in children with spastic tetraplegia. The risk of displacement (MP > 40% was directly related to the level of gross motor function, classified according to the gross motor function classification system, GMFCS, from 0% in children in GMFCS level I to 64% in GMFCS level V. Conclusion Hip displacement in CP often occurs already at 2–3 years of age. Range of motion is a poor indicator of hips at risk. Thus early identification and early radiographic examination of children at risk is of great importance. The risk of hip displacement varies according to both CP-subtype and GMFCS. It is sometimes not possible to determine subtype before 4 years of age, and at present several definitions and classification systems are used. GMFCS is valid and reliable from 2 years of age, and it is internationally accepted. We recommend a hip

  13. Comparison of three methods to diagnose hip dysplasia in dogs

    The present study was designed to compare the usefulness of goniometry, radiography and distraction index in diagnosis of hip dysplasia in dogs. During the study 25 clinical cases (50 joints) suspected for hip dysplasia were evaluated. Norberg angle was found to have a significant positive correlation with extension, flexion, abduction, and adduction angles and a significant negative correlation with distraction index (DI) measurements. It could be inferred that all the six parameters (NA, DI, extension, flexion, abduction, and adduction) were reliable indicators for early diagnosis of hip dysplasia.Goniometry could be used as a safe and easy method for preliminary suspicion of hip dysplasia

  17. Hip and pelvis diseases on lumbar AP radiographs including both hip joints

    To determine the frequency of disease, and to evaluate the methods used for lumbar spine radiography in Korea. Sixty university and training hospitals were randomly selected and asked to describe the projections, film size and radiographic techniques employed for routine radiography in patients with suspected disease of the lumbar spine. Plain radiographs of 1215 patients, taken using 14x17 inch film and depicting both hip joints and the lumbar region, were analysed between March 1999 and February 2000. In 15 patients (1.2%), the radiographs revealed hip or pelvic lesion, confirmed as follows: avascular necrosis of the femoral head (n=11, with bilateral lesion in four cases); sustained ankylosing spondylitis (n=2); acetabular dysplasia (n=1); and insufficiency fracture of the pubic rami secondary to osteoporosis (n=1). In 11 or the 20 hospitals which responded, 14x17film was being used for lumbar radiography, while in the other nine, film size was smaller. Plain radiography of the lumbar spine including both hip joints, may be a useful way to simultaneously evaluate lesions not only of the lumbar spine but also of the hip and/or pelvis

  1. Primary abductor hip contracture as diagnostic, prognostic and therapeutic problem in child hip pathology

    Pajić Miloš

    2007-01-01

    Full Text Available Coxa obliqua represents a special functional entity in the pathology of the child hip. Authors have confirmed the results of S.L. Weissman and B. Strinovic which claimed that the abductor contracture of the hip was a primary congenital condition that developed as a result of intrauterine malposition, leading later to the contralateral adductor contracture. Critical period for the development of complications was between 6 and 8 month after birth, adductor contracture might keep persisting together with the development of acetabular dysplasia, and later on with ipsilateral subluxation. This malformation has usually been diagnosed within 3 and 6 months of age. It could be connected with some other signs of malposition, such as plagiocephaly, torticollis or infantile thoracic C scoliosis. For the diagnosis of coxa obliqua, the examination of hips in the prone position was very important and the ultrasonic and radiological examinations were crucial. The applied treatment used to be exclusively physical rehabilitation. Wide diapering has been contraindicated. In this study, we included 2,500 newborns, 1,300 boys and 1,200 girls (5,000 hips. In 22 cases of coxa obliqua (10‰, the excellent results were obtained in 96% of cases. In two unsuccessfully treated cases, a contralateral dysplasia developed, and in one untreated, subluxation. The authors are advocating a systematic and early detection and treatment of the primary coxa obliqua. .

  2. Inequalities in use of total hip arthroplasty for hip fracture: population based study

    Metcalfe, David; Griffin, Xavier L; Costa, Matthew L

    2016-01-01

    Objectives To determine whether the use of total hip arthroplasty (THA) among individuals with a displaced intracapsular fracture of the femoral neck is based on national guidelines or if there are systematic inequalities. Design Observational cohort study using the National Hip Fracture Database (NHFD). Setting All hospitals that treat adults with hip fractures in England, Wales, and Northern Ireland. Participants Patients within the national database (all aged ≥60) who received operative treatment for a non-pathological displaced intracapsular hip fracture from 1 July 2011 to 31 April 2015. Main outcome measures Provision of THA to patients considered eligible under criteria published by the National Institute for Health and Care Excellence (NICE). Results 114 119 patients with hip fracture were included, 11 683 (10.2%) of whom underwent THA. Of those who satisfied the NICE criteria, 32% (6780)received a THA. Of patients who underwent THA, 42% (4903) did not satisfy the NICE criteria. A recursive partitioning algorithm found that the NICE eligibility criteria did not optimally explain which patients underwent THA. A model with superior explanatory power drew distinctions that are not supported by NICE, which were an age cut off at 76 and a different ambulation cut off. Among patients who satisfied the NICE eligibility, the use of THA was less likely with higher age (odds ratio 0.88, 95% confidence interval 0.87 to 0.88), worsening abbreviated mental test scores (0.49 (0.41 to 0.58) for normal cognition v borderline cognitive impairment)), worsening American Society of Anesthesiologists score (0.74, 0.66 to 0.84), male sex (0.85, 0.77 to 0.93), worsening ambulatory status (0.32, 0.28 to 0.35 for walking with a stick v independent ambulation), and fifths of worsening socioeconomic area deprivation (0.76 (0.66 to 0.88) for least v most deprived fifth). Patients receiving treatment during the working week were more likely to receive THA than at the

  3. Return to Play Following Hip Arthroscopy.

    Lee, Simon; Kuhn, Andrew; Draovitch, Pete; Bedi, Asheesh

    2016-10-01

    Femoroacetabular impingement may be particularly disabling to the high-demand athlete, especially those with significant cutting and pivoting requirements. If nonoperative treatment fails to adequately alleviate symptoms or sufficiently restore function in the athlete, hip arthroscopy can lead to improved pain, improved range of motion, and high rates of return to play with proper postoperative rehabilitation. The rate of return to previous level of competition is also high with accurate diagnosis and well-executed correction of deformity. A clear understanding of the etiology, diagnosis, management, and outcomes is essential for clinicians to optimally help patients to return to play. PMID:27543404

  4. Hip Instability: Current Concepts and Treatment Options.

    Dumont, Guillaume D

    2016-07-01

    Instability of the hip can manifest in a wide range of settings, with presenting symptoms including subtle discomfort at end range of motion or more dramatic dislocation of the joint. It can result from traumatic injury with dislocation or subluxation; atraumatic capsular laxity; structural bony abnormality, such as acetabular dysplasia; and iatrogenic injury. Initial treatment of the concentrically reduced joint often begins with physical therapy to strengthen dynamic stabilizers and to allow time for resolution of acute symptoms. Surgical treatment is aimed at repairing injured soft tissue structures, including static stabilizers, and addressing underlying bony structural deficiencies. PMID:27343395

  5. Hip labral cyst caused by psoas impingement.

    Tey, Marc; Alvarez, Sonia; Ríos, Jose L

    2012-08-01

    Hip labral impingement can cause labral tears and secondary paralabral cyst formation. Femoroacetabular impingement is the main cause of labral impingement, but other conditions such as iliopsoas tendon impingement are described. There is no description of labral cyst resulting from psoas impingement treated arthroscopically in the literature. We present the case of a young sportsman with groin pain caused by psoas impingement with a labral tear and secondary paralabral cyst who was treated arthroscopically by cyst debridement, psoas tenotomy, and labral repair.

  10. Hip and knee arthroplasty: quo vadis?

    Ho, J; Meis, J. F. G. M.; Nabuurs-Franssen, M.H.; Voss, A.

    2015-01-01

    Despite of the steady decrease of surgical site infection (SSI) over the last two decades, the incidence of SSI after hip and knee arthroplasty has recently surged. This may be explained by technical changes that may result in an increased risk of SSI, such as the broad implementation of fast track programs, and/or early interventions on suspected SSI. By definition, early intervention may lead to a higher SSI score, even in the absence of a true SSI. In any case, the reverse trend of SSI war...

  11. A novel DXA-based hip failure index captures hip fragility independent of BMD.

    Sievänen, H; Weynand, L S; Wacker, W K; Simonelli, C; Burke, P K; Ragi, S; Del Rio, L

    2008-01-01

    Capability of a novel dual-energy X-ray absorptiometry (DXA)-based hip failure index (HiFI) to discriminate between hip fracture cases and controls was evaluated. Given the constraints of planar DXA, the femoral neck was assumed a foam-filled ( approximately trabecular bone), thin-walled ( approximately cortical bone) sandwich structure, while HiFI estimated the critical force sufficient to buckle the wall of such a structure. Proximal femur DXA data from 1379 women aged 65yr and older, 268 with prior hip fracture were used. Comparison between standard areal bone mineral density (BMD), femur strength index (FSI), and HiFI was based on areas under receiver operatoring characteristic curves (AUC). The mean femoral neck BMD (SD) was 0.689 (0.109) g/cm(2) among the cases and 0.768 (0.119) g/cm(2) among the controls; the mean FSI 1.33 (0.36) and 1.54 (0.41), and the mean HiFI -0.28 (0.14) and -0.18 (0.15), respectively; all intergroup differences were highly significant (pHiFI remained significant (pHiFI. In conclusion, HiFI may capture structural traits that account for femoral neck fragility independently of BMD or FSI. Obviously, the use of actual geometric and structural information from three-dimensional imaging of the femoral neck would help diminish the crude assumptions of the present DXA approach and reveal the true potential of the HiFI approach to gauge hip fragility and identify at-risk individuals for hip fractures.

  12. Hybrid SPECT/CT for the assessment of a painful hip after uncemented total hip arthroplasty

    The diagnosis of hip pain after total hip replacement (THR) represents a highly challenging question that is of increasing concern to orthopedic surgeons. This retrospective study assesses bone scintigraphy with Hybrid SPECT/CT for the diagnosis of painful THR in a selected cohort of patients. Bone SPECT/CT datasets of 23 patients (mean age 68.9 years) with a painful hip after THR were evaluated. Selection of the patients required an inconclusive radiograph, normal serum levels of inflammatory parameters (CRP and ESR) or a negative aspiration of the hip joint prior to the examination. The standard of reference was established by an interdisciplinary adjudication-panel using all imaging data and clinical follow-up data (>12 month). Pathological and physiological uptake patterns were defined and applied. The cause of pain in this study group could be determined in 18 out of 23 cases. Reasons were aseptic loosening (n = 5), spine-related (n = 5), heterotopic ossification (n = 5), neuronal (n = 1), septic loosening (n = 1) and periprosthetic stress fracture (n = 1). In (n = 5) cases the cause of hip pain could not be identified. SPECT/CT imaging correctly identified the cause of pain in (n = 13) cases, in which the integrated CT-information led to the correct diagnosis in (n = 4) cases, mainly through superior anatomic correlation. Loosening was correctly assessed in all cases with a definite diagnosis. SPECT/CT of THA reliably detects or rules out loosening and provides valuable information about heterotopic ossifications. Furthermore differential diagnoses may be detected with a whole-body scan and mechanical or osseous failure is covered by CT-imaging. SPECT/CT holds great potential for imaging-based assessment of painful prostheses

    2004-01-01

    Objective:To evaluate the outcome of total hip arthroplasty (THA) with cementless cups and femoral head autografts for patients with hip dysplasia and osteoarthritis.Methods: Between 1995 and 2002, we implanted 23cementless cups and femoral head autografts in 20 patients with hip dysplasia and osteoarthritis. In this study, a retrospective study was made on 21 hips in 20 patients (18females and 2 males, aged 50 years on an average) with developmental hip dysplasia treated by THA with acementless cup and femoral head autograft. The acetabular cup was placed at the level of the true acetabuinm and all the patients required autogenous femoral head grafts due to acetabular deficiency. The average rate of the acetabular cup covered by the femoral head autograft was 31%(ranging from 10% to 45%). Eight hips had less than 25%cup coverage and thirteen between 25% and 50%. The average follow-up period was 4.7 years (range, 1-8 years).The replacing outcome was evaluated by modified Harris hip score. Preoperative and follow-up radiographs were made.Results: All the autografts were united to the host bones. No autograft was collapsed or no component from the hip was loosed in all the patients. According to the modified Harris hip score, the average hip score increased from 46 before operation to 89 at the final review. Before operation, the leg-length discrepancy was greater than 2 cm in all the patients except one with bilateral hip dysplasia.After operation, only 2 out of 20 patients had a leg-length discrepancy greater than 1 cm. Three hips showed minor bone resorption in the lateral portion of the graft, which did not support the cup. Three hips developed Grade 1Brooker heterotopic ossification and one developed Grade 2.Conclusions: THA with a cementless cup and a femoral head autograft for patients with osteoarthritis resulted from hip dysplasia can result in favorable outcomes. This method can provide reliable acetabular fixation and restore the acetabular bone stock in

  14. Development of HIP bonding procedure and mechanical properties of HIP bonded joints for reduced activation ferritic steel F-82H

    Structural materials of blanket components in fusion DEMO reactors will receive a neutron wall load more than 3-5MW/m2 as well as exposed by surface heat flux more than 0.5MW/m2. A reduced activation ferritic steel F-82H has been developed by JAERI in collaboration with NKK from viewpoints of resistance for high temperature and neutron loads and lower radioactivity. This study intends to obtain basic performance of F-82H to establish the fabrication procedure of the first wall and blanket box by using Hot Isostatic Pressing (HIP) bonding. Before HIP bonding tests, effects of heat treatment temperature and surface roughness on mechanical properties of joints were investigated in the heat treatment tests and diffusion bonding tests, respectively. From these results, the optimum HIP bonding conditions and the post heat treatment were selected. Using these conditions, the HIP bonding tests were carried out to evaluate HIP bondability and to obtain mechanical properties of the joints. Sufficient HIP bonding performance was obtained under the temperature of 1040degC, the compressive stress of 150MPa, the holding time of 2h, and the surface roughness ∼μ m. Mechanical properties of HIP bonded joints with these conditions were similar to those of as-received base metal. An oxide formation on the surface to be bonded would need to be avoided for sufficient bonding. The bonding ratio, Charpy impact value and fatigue performance of the joints strongly depended on the HIP conditions, especially temperature, while micro-structure, Vickers hardness and tensile properties had little dependence on the HIP temperature. The surface roughness strongly affected the bonding ratio and would be required to be in the level of a few μ m. In the HIP bonding test of the welded material, the once-melted surface could be jointed by the HIP bonding under the above-mentioned procedure. (J.P.N.)

  18. Extreme Kinematics in Selected Hip Hop Dance Sequences.

    Bronner, Shaw; Ojofeitimi, Sheyi; Woo, Helen

    2015-09-01

    Hip hop dance has many styles including breakdance (breaking), house, popping and locking, funk, streetdance, krumping, Memphis jookin', and voguing. These movements combine the complexity of dance choreography with the challenges of gymnastics and acrobatic movements. Despite high injury rates in hip hop dance, particularly in breakdance, to date there are no published biomechanical studies in this population. The purpose of this study was to compare representative hip hop steps found in breakdance (toprock and breaking) and house and provide descriptive statistics of the angular displacements that occurred in these sequences. Six expert female hip hop dancers performed three choreographed dance sequences, top rock, breaking, and house, to standardized music-based tempos. Hip, knee, and ankle kinematics were collected during sequences that were 18 to 30 sec long. Hip, knee, and ankle three-dimensional peak joint angles were compared in repeated measures ANOVAs with post hoc tests where appropriate (p<0.01). Peak angles of the breaking sequence, which included floorwork, exceeded the other two sequences in the majority of planes and joints. Hip hop maximal joint angles exceeded reported activities of daily living and high injury sports such as gymnastics. Hip hop dancers work at weight-bearing joint end ranges where muscles are at a functional disadvantage. These results may explain why lower extremity injury rates are high in this population.

    2010-10-01

    Failed treatment of an intertrochanteric fracture typically leads to profound functional disability and pain. Salvage treatment with hip arthroplasty may be considered. The aim of this study was to evaluate the results and complications of hip arthroplasty performed as a salvage procedure after the failed treatment of an intertrochanteric hip fracture. Twenty-one patients were treated in our hospital with hip arthroplasty for failed treatment of intertrochanteric hip fracture. There were sixteen women and five men with a mean age of 75.8 years (range 61-85 years). Fourteen patients had failure of a previous nail fixation procedure, five had failure of a plate fixation, one of hip screws fixation and one of Ender nail fixation. In 19 out of 21 patients we performed a total hip arthroplasty-14 cases used modular implants with long-stems and five cases used a standard straight stem. In 2 of 21 cases we used a bipolar hemiarthroplasty. A statistically significant improvement was found comparing pre and postoperative conditions (p < 0.05). Our experience confirms that total hip arthroplasty is a satisfactory salvage procedure after failed treatment of an intertrochanteric fracture in elderly patients with few serious orthopaedic complications and acceptable clinical outcomes.

  5. HIP ROTATIONAL VELOCITIES DURING THE FULL GOLF SWING

    Heather Gulgin

    2009-06-01

    Full Text Available Since labral pathology in professional golfers has been reported, and such pathology has been associated with internal/external hip rotation, quantifying the rotational velocity of the hips during the golf swing may be helpful in understanding the mechanism involved in labral injury. Thus, the purpose of this study was to determine the peak internal/external rotational velocities of the thigh relative to the pelvis during the golf swing. Fifteen female, collegiate golfers participated in the study. Data were acquired through high-speed three dimensional (3-D videography using a multi-segment bilateral marker set to define the segments, while the subjects completed multiple repetitions of a drive. The results indicated that the lead hip peak internal rotational velocity was significantly greater than that of the trail hip external rotational velocity (p = 0.003. It appears that the lead hip of a golfer experiences much higher rotational velocities during the downswing than that of the trail hip. In other structures, such as the shoulder, an increased risk of soft tissue injury has been associated with high levels of rotational velocity. This may indicate that, in golfers, the lead hip may be more susceptible to injury such as labral tears than that of the trailing hip

  11. Imaging of sports-related hip and groin injuries.

    Lischuk, Andrew W; Dorantes, Thomas M; Wong, William; Haims, Andrew H

    2010-05-01

    A normally functioning hip joint is imperative for athletes who use their lower extremities with running, jumping, or kicking activities. Sports-related injuries of the hip and groin are far less frequent than injuries to the more distal aspect of the extremity, accounting for less than 10% of lower extremity injuries. Despite the lower incidence, hip and groin injuries can lead to significant clinical and diagnostic challenges related to the complex anatomy and biomechanical considerations of this region. Loads up to 8 times normal body weight have been documented in the joint in common daily activities, such as jogging, with significantly greater force expected during competitive athletics. Additionally, treatment for hip and groin injuries can obviate the participation of medical and surgical specialties, with a multidisciplinary approach frequently required. Delay in diagnosis and triage of these injuries may cause loss of time from competition and, potentially, early onset of degenerative changes. Magnetic resonance imaging (MRI) of the hip has proven to be the gold standard for the diagnosis of sports-related hip and groin injuries in the setting of negative radiographs. With its exquisite soft tissue contrast, multiplanar capabilities, and lack of ionizing radiation, MRI is unmatched in the noninvasive diagnosis of intra-articular and extra-articular pathology, as well as intraosseous processes. This review focuses on MRI of common athletic injuries of the hip and groin, including acetabular labral tears, femoral acetabular impingement syndrome, muscle injuries around the hip and groin (including athletic pubalgia), and athletic osseous injuries.

  14. Paralytic dislocations of the hip in adolescence: Orthopaedic treatment

    Čobeljić Goran

    2009-01-01

    Full Text Available Paralytic dislocation of the hip in adolescence is not typical, but presents a serious problem whether diagnosed primarily in adolescence or due to the lack of treatment or failed treatment in earlier age. It is characteristic of cerebral palsy and myelomeningocele. If the paralytic dislocation of the hip in adolescence is asymmetric, then pelvic obliquity, leg-length discrepancy, imbalance in sitting position, scoliosis and secondary spondylosis with all its consequences ensue. Complications like hip pains due to secondary arthrosis and walking ability impairment are frequent in ambulatory patients. The dislocation is the result of muscle imbalances in the hip region. The diagnosis is based on Illness history, clinical examination, neurological examination and radiography. Treatment is mostly operative, except in cases of pelvic symmetry and absence of difficulties. Pelvic and/or femoral osteotomy with or without open reduction of the hip is done in ambulatory patients with cerebral palsy. Soft-tissue surgery, hip flexors release and tenotomy of the hip adductors, are done in non-ambulatory patients with cerebral palsy. In patients with myelomeningocele soft-tissue surgery, hip flexors release and tractus iliotibialis resection on the lower side of the pelvis, are done regardless of the ability to walk. The same bone surgery procedures as in cerebral palsy are done only in ambulatory patients with unilateral dislocations if soft-tissue surgery failed.

  18. Structural integrity evaluation for HIP bonded fusion DEMO reactor component

    HIP (Hot Isostatic Pressing) is applicable to fabrication technology for in-vessel components of fusion DEMO reactor, which has been fabricated by ferritic steel F82H. Verification of structural integrity of HIP bonded joint is one of the most important subjects on the development of fusion DEMO reactor component. Even now structural integrity evaluation method for HIP bonded joint is not enough estimated. This paper describes the results of low cycle fatigue test and inelastic analysis using HIP-element model under the bending load of fusion DEMO reactor. Low cycle fatigue strength and fracture/deformation mode has been obtained. SEM-observation was performed at the fracture surface of HIP-element model and the bonded joints between cooling tubes and plate were inspected. (author)

  19. Influence of anaesthesia on canine hip dysplasia score.

    Genevois, J-P; Chanoit, G; Carozzo, C; Remy, D; Fau, D; Viguier, E

    2006-10-01

    Hip dysplasia (HD) scores, based on the five grades, as defined by the Fédération Cynologique Internationale, were compared between anaesthetized (group 1, n = 3839) and non-sedated non-anaesthetized dogs (group 2, n = 1517). Each dog was radiographed in the standard ventro-dorsal hip joint extended position. Each radiograph was evaluated by the same reader blinded regarding the dog's status of anaesthesia. Results showed that there was a significant difference in hip dysplasia prevalence between group 1 (22%) compared with group 2 (9%) (P < 0.005). This difference was the result of a lower rate of hip-joint laxity assessment and the measurement of Norberg-Olsson angle <105 degrees in group 2 compared with group 1. The acetabular and femoral morphologies were not significantly different between the groups. The data confirm that the scoring of dogs for HD on standard radiographs with the hip joints extended is influenced by anaesthesia. PMID:16970631

  2. The innervation of canine hip joint capsule: an anatomic study.

    Huang, C H; Hou, S M; Yeh, L S

    2013-12-01

    To clarify the contributions of the nerves supplying the canine hip joint capsule for clinical application, cadaver study of six healthy mongrel dogs was performed. The pelvises and hindlimbs of cadavers were dissected and fixed in formaldehyde. Innervation of the joint capsule was investigated with the aid of an operative microscope. As a result, the canine hip joint capsule receives multiple innervations from articular branches of four nerves. They are articular nerve fibres of femoral, obturator, cranial gluteal and sciatic nerves from the cranioventral, caudoventral, craniolateral and dorsolateral directions of the joint, respectively. No branch originating from the caudal gluteal nerve was observed innervating the hip joint capsule. Our data provides useful information for research on the canine hip joint, including pain analysis with hip disorders and surgical nerve blockade to relieve pain. PMID:23410229

  3. Current Challenges in Pain Management in Hip Fracture Patients.

    Sanzone, Anthony G

    2016-05-01

    The high incidence of hip fracture, together with considerable associated morbidity, mortality, and cost of care, makes this injury a major clinical challenge. Of particular importance is the pain associated with hip fracture, which can have potentially severe consequences and may lead to delayed recovery. The prevailing opioid-dependent model of analgesia, however, presents multiple drawbacks and risks that can compromise outcomes in the hip fracture population. The pain management process has essential preoperative, intraoperative, and postoperative components, yet data on the comparative effectiveness of different pain management interventions in patients undergoing surgery for hip fracture are not clear cut. A Cochrane database review that included 83 different pain management studies indicated that there are not enough well-designed studies to show unequivocally which pain management approaches work well after hip fracture surgery. Yet a growing body of data on certain interventions, such as nerve blocks and multimodal analgesia, supports consideration of these options. PMID:27101319

  4. Bernese periacetabular osteotomy for hip dysplasia: Surgical technique and indications.

    Kamath, Atul F

    2016-05-18

    For young, active patients with healthy hip cartilage, pelvic osteotomy is a surgical option in to address hip pain and to improve mechanical loading conditions related to dysplasia. Hip dysplasia may lead to arthrosis at an early age due to poor coverage of the femoral head and abnormal loading of the joint articulation. In patients with symptomatic dysplasia and closed triradiate cartilage (generally over age 10), including adolescents and young adults (generally up to around age 40), the Bernese periacetabular osteotomy (PAO) is a durable technique for addressing underlying structural deformity. The PAO involves a modified Smith-Petersen approach. Advantages of the Bernese osteotomy include preservation of the weight-bearing posterior column of the hemi-pelvis, preservation of the acetabular blood supply, maintenance of the hip abductor musculature, and the ability to effect powerful deformity correction about an ideal center of rotation. There is an increasing body of evidence that preservation of the native hip can be improved through pelvic osteotomy. In contrast to hip osteotomy and joint preservation, the role of total hip arthroplasty in young, active patients with correctable hip deformity remains controversial. Moreover, the durability of hip replacement in young patients is inherently limited. Pelvic osteotomy should be considered the preferred method to address correctable structural deformity of the hip in the young, active patient with developmental dysplasia. The Bernese PAO is technically demanding, yet offers reproducible results with good long-term survivorship in carefully selected patients with preserved cartilage and the ability to meet the demands of rehabilitation.

  5. Hip injuries in children and adolescents.

    Craig, C L

    1980-10-01

    Hip injuries in children present a wide spectrum of problems. Frequently because of the severity of the trauma involved, other injuries may take precedence and may require modification of the usual approaches to treatment. However, certain precepts are essential to the successful treatment of these injuries and should be kept in mind regardless of the milieu in which they are found. In the child with a hip dislocation, the potential presence of an acetabular, femoral head, femoral shaft, patellar or tibial plateau fracture must always be considered. Specialized x-ray views are necessary for this evaluation. Laminography and arthrography may also be required. The essential feature of successful subsequent treatment is a gentle closed reduction performed within 24 hours of injury. Treatment of displaced fractures of the femoral neck remains an unresolved issue. Accurate reduction held with adequate internal fixation would appear to offer the best chance for a successful result. The possible complications of avascular necrosis, delayed union and non-union, coxa vara, premature closure of the epiphyseal plate, and shortening should be appreciated. Early institution of appropriate treatment may mitigate the ultimate effect of these potentially devastating problems. PMID:7454245

  6. Robot-assisted total hip arthroplasty.

    Banerjee, Samik; Cherian, Jeffery J; Elmallah, Randa K; Pierce, Todd P; Jauregui, Julio J; Mont, Michael A

    2016-01-01

    Precise and accurate biomechanical reconstruction during total hip arthroplasty (THA) is essential for durable long-term survivorship. Accurate fit of cementless hip implants is also crucial to reduce micromotion between the bone-implant interfaces to allow for stable osseointegration. Robotic technology aims to minimize potential human errors and improve implant alignment and fit, and address persisting concerns with modern-day cementless THA. Although robotic THA dates back to the early 1990s, concerns with increased operating times, costs, and complications led to its withdrawal. However, semi-active systems have renewed interest in robot-assisted joint arthroplasty. We reviewed the current technology, its potential benefits, and the reported clinical and radiographic outcomes. Early evidence suggests that robotic use may lead to more accurate reconstruction of radiographic parameters, such as implant positioning, fit, center-of-rotation, and leg-length discrepancy. Further research is needed to determine if these will translate into better outcomes and improved implant longevity to justify increased costs. PMID:26592900

    2014-12-01

    Full Text Available Aim: The purpose of the study was to determine the prevalence, incidence, and etiology as well as the risk factors for developmental dysplasia of the hip in newborns in whom we performed ultrasonography for screening using Graff’s method in our clinic. Methods: We retrospectively evaluated 2632 hip ultrasonography records of 1316 babies performed between 2008 and 2013. We analyzed the questionnaires of the Turkish Pediatric Orthopaedic Society which were filled by the physician during examination. The babies were divided into two groups according to ultrasonographic hip angles as pathological and normal. Results: The study is made on 1316 babies [680 girls (51.6%, 636 boys (48.4%]. The risk for developmental dysplasia of the hip was higher in girls, babies with a family history, babies with metatarsus adductus and those have been swaddled before. The mean gestational age and gestational weight was statistically significantly lower in the pathological group (p=0.0011. Conclusion: In our cross-sectional study, the incidence of developmental dysplasia of the hip was 0.5%. Female gender, positive family history of developmental dysplasia of the hip,metatarsus adductus and swaddling are still risk factors. Researching risk factors carefully, patient education and adding hip ultrasonograpy to newborn routine screening program are important measures in preventing developmental dysplasia of the hip.

  12. Protocol of plain radiographs, hip ultrasound, and triple phase bone scans in the evaluation of the painful pediatric hip

    A useful protocol for the evaluation of hip pain in the pediatric patient, using a combination of plain radiographs, hip ultrasound (US), and triple phase radionuclide bone scans is presented. Patients with hip pain were initially evaluated by plain radiographs of the pelvis and hips. If no diagnosis was reached, the hips were studied for effusions by real-time hip ultrasonography. If an effusion was present, the joint was aspirated for diagnosis. If no effusion was present by US or if no diagnosis was reached by aspiration, triple phase radionuclide bone scans were performed. Fifty patients were evaluated by this prospective protocol, and the diagnosis was reached in 48 of the 50 cases (10 by plain radiographs, 16 by US, and aspiration of the joint, and 22 by triple phase bone scans). Hip effusions were found in 20 patients by US, with no false positives or false negatives. Previous studies for detecting effusions by US have emphasized absolute measurements of the capsular width, but we report a typical appearance of the hip capsule when fluid is present (a bulging convex capsule). When no effusion is present, the capsule is concave and parallels the long axis of the femoral neck

  14. Characterization of the Neural Anatomy in the Hip Joint to Optimize Periarticular Regional Anesthesia in Total Hip Arthroplasty.

    Simons, Matthew J; Amin, Nirav H; Cushner, Fred D; Scuderi, Giles R

    2015-01-01

    The purpose of the current study was to identify and map the periarticular neural anatomy of the hip to optimize periarticular injection techniques in total hip arthroplasty. A literature review of common search engines was performed using terms associated with hip innervation and 17 met the inclusion criteria. The studies addressed both gross and microscopic neural anatomy of the human hip joint, and the findings summarize key areas of hip mechanoreceptors and free nerve endings to provide a framework for targeted periarticular hip infiltration. Grossly, the hip joint is supplied by the femoral, obturator, sciatic, and superior gluteal nerves, as well as the nerve to the quadratus femoris. The greatest concentration of sensory nerve endings and mechanoreceptors is found at the anterior hip capsule, especially superiorly. The labrum is most highly innervated from the 10 to 2 o'clock position. After the cup and liner are placed, periarticular injections should be infiltrated toward the remnant labrum from 10 to 2 o'clock. Before stem insertion, the visible periosteum may then be injected circumferentially about the femur. The anterior and superior capsular tissue, if retained, is routinely infiltrated at the time of capsular repair. Depending on surgical approach, the fascia and incised soft tissue are infiltrated before final closure. PMID:26731384

    2012-01-01

    Background Developmental dysplasia encompasses a wide spectrum of hip pathology ranging from a shallow acetabulum to a completely dislocated ‘high-riding' hip.It is a common cause of secondary osteoarthritis in young adults and is the underlying diagnosis in up to 48% of patients requiring total hip arthroplasty (THA) for coxarthrosis.The aim of this study was to evaluate efficiency and safety of THA using Zweymüller hip implant in the treatment of severe osteoarthritis secondary to developmental dysplasia of the hip (DDH) in adults.Methods From January 2000 to February 2008,35 patients (40 hips) with developmental dysplasia of the hip were included.Five were male and 30 were female,with ages ranging from 26 to 65 years and an average age of 45 years.According to Hartofilakidis classification,there were type Ⅰ in 5 hips,type Ⅱ in 20 hips,type Ⅲ in 15 hips.All the patients were performed the THA using the Zweymüller hip implant.The preoperative average Harris score was 44.The bilateral arthroplasty was performed in 5 patients and the unilateral arthroplasty in 30 patients.The patients mainly suffered from pain and claudication.Clinical and radiological results were analyzed.The Harris score was used for outcome measurement.Results Thirty five patients (40 hips) were followed and the mean follow-up period was 46 months (ranged from 24 months to 96 months).The latest follow-up average Harris score was 88.9 (97.1% of good rate).All the patients were pain-free and there was no sign of infection,aseptic loosening and subsidence.Conclusions In summary,THA using Zweymüller hip implant is a good treatment method for severe osteoarthritis secondary to DDH in adults.The key techniques for the total hip replacement are as follows:good preoperative plan,firmly placing the acetabular component in the true acetabulum,proper preparation of proximal femur,suitable femoral component choosing and improving the techniques of the bone graft.

    Before the re-introduction of the current generation of total hip resurfacing arthroplasty, component loosening and osteolysis were of great concern to the orthopaedic community. Early, mid- and long-term clinical results are encouraging, but component loosening still exists. Macroscopic, contact radiographic and histopathological analyses after undecalcified preparation of bone tissue specimens were performed. To investigate the frequency and morphological patterns of the loosening of the femoral component, we analysed a series of 190 retrieved femoral remnants that were revised for aseptic failures. Thirty-five (18.4%) hips were revised for clinical and/or radiographic loosening of the femoral component. Pseudoarthrosis (n = 17; median in situ time: 16 weeks, interquartile range [IQR]: 9 to 34), collapsed osteonecrosis (n = 5; median in situ time: 79 weeks, IQR: 63 to 97), cement-socket debonding (n = 3; median in situ time: 89 weeks, IQR: 54 to 97) and at later follow-up bone-cement loosening (n = 10; median in situ time: 175 weeks; IQR 112 to 198; p =0.005) were distinct patterns of the femoral remnant-implant loosening. Fibrocartilaginous metaplasia of interface bone trabeculae (n = 38; median in situ time: 61 weeks, IQR: 32 to 138) was strongly associated with femoral component loosening (p = 0.009). Both the trabecular hyperosteoidosis (n = 32; median in situ time: 71 weeks, IQR 50 to 129) and excessive intraosseous lymphocyte infiltration (n = 12; median in situ time: 75 weeks, IQR 51 to 98) at the bone-cement interface correlated strongly with fibrocartilaginous metaplasia (p = 0.001 and p = 0.016 respectively) and all three lesions were associated with the female gender (p = 0.021, p = 0.009, and p = 0.051). Femoral component loosening at early follow-up was mostly caused by pathological changes of the femoral remnant bone tissue: pseudoarthrosis and collapsed osteonecrosis. Fibrocartilaginous metaplasia was frequently observed in hips with femoral

    2010-02-15

    The aim of this study is to evaluate the MR imaging features of patients with external snapping hip syndrome. We retrospectively reviewed 63 hip MR images. The images were analyzed according to the thickness and contour of the iliotibial band and the gluteus maximus, the presence of bone marrow edema, bursitis, joint effusion and other associated findings. The MR imaging of 22 hips with snapping hip syndrome depicted the causes of external snapping hip syndrome in twenty cases (90%). The MR imaging features of the snapping hip included thickening of the iliotibial band in twelve cases (55%) and/or thickening of the anterior band of the gluteus maximus in nineteen (86%), and a wavy contour of the iliotibial band or the anterior band of the gluteus maximus in ten cases (45%). These findings show a significant p value (<0.01). The majority of patients with snapping hip syndrome revealed thickening of the iliotibial band, thickening of the anterior band of the gluteus maximus and wavy contour of the those structures on MR imaging.

  1. Assessment of hip dysplasia and osteoarthritis: Variability of different methods

    Troelsen, Anders; Elmengaard, Brian; Soeballe, Kjeld (Orthopedic Research Unit, Univ. Hospital of Aarhus, Aarhus (Denmark)), e-mail: a_troelsen@hotmail.com; Roemer, Lone (Dept. of Radiology, Univ. Hospital of Aarhus, Aarhus (Denmark)); Kring, Soeren (Dept. of Orthopedic Surgery, Aabenraa Hospital, Aabenraa (Denmark))

    2010-03-15

    Background: Reliable assessment of hip dysplasia and osteoarthritis is crucial in young adults who may benefit from joint-preserving surgery. Purpose: To investigate the variability of different methods for diagnostic assessment of hip dysplasia and osteoarthritis. Material and Methods: By each of four observers, two assessments were done by vision and two by angle construction. For both methods, the intra- and interobserver variability of center-edge and acetabular index angle assessment were analyzed. The observers' ability to diagnose hip dysplasia and osteoarthritis were assessed. All measures were compared to those made on computed tomography scan. Results: Intra- and interobserver variability of angle assessment was less when angles were drawn compared with assessment by vision, and the observers' ability to diagnose hip dysplasia improved when angles were drawn. Assessment of osteoarthritis in general showed poor agreement with findings on computed tomography scan. Conclusion: We recommend that angles always should be drawn for assessment of hip dysplasia on pelvic radiographs. Given the inherent variability of diagnostic assessment of hip dysplasia, a computed tomography scan could be considered in patients with relevant hip symptoms and a center-edge angle between 20 deg and 30 deg. Osteoarthritis should be assessed by measuring the joint space width or by classifying the Toennis grade as either 0-1 or 2-3

    Full Text Available Aim: We aimed to determine the frequency of cases with developmental hip dysplasia during the neonatal period and the associated risk factors. Methods: Hip ultrasound images of 258 full-term newborns aged one month were evaluated prospectively in conjunction with physical examination for developmental hip dysplasia in GATA well baby outpatient clinic. Results: The incidence of developmental hip dysplasia was 0.3% in one-month-old, healthy, full-term babies included in the study. 44% of them were male and 56% were female. The mean birth weight was 3311.8±511.4 g. 48% of all births were spontaneous vaginal deliveries and 52% cesarean deliveries. A history of oligohydramniosis was present in 8% of cases, 1% had breech presentation, 7% had a family history of developmental dysplasia and 7% had been swaddled. Additional congenital anomaly and torticollis were not detected at the physical examination of the babies. The risk factors were determined to be twin birth and female gender in the only baby who had developmental hip dysplasia (Type 2a. Conclusion: Developmental hip displasia is a significant public health concern in developing countries. Physical examination performed in conjunction with hip ultrasonography routinely in the neonatal period may contribute to the early diagnosis and treatment.

  3. MR imaging of transient osteoporosis of the hip: An update on 155 hip joints

    Highlights: •Characteristics of TOH are described based on the largest series of patients in the literature. •The chance of regional migratory osteoporosis progression is estimated to be 19.4%. •The pattern of bone marrow edema with respect to symptom duration is described. •The prevalence of subchondral microfractures is high in TOH patients. •Microfractures are not complicated with avascular necrosis or articular collapse. -- Abstract: Purpose: Transient osteoporosis of the hip (TOH) presents with acute onset pain and bone marrow edema (BMe) on MR imaging. The purpose of this study is to revise the MR imaging characteristics of TOH by analyzing the data derived from 155 hip examinations. We also sought to explore the relationship between the duration of symptoms and the presence of sparing and subchondral fractures. Materials and methods: MR images of 155 hips (141 TOH patients) were retrospectively evaluated for the presence of insufficiency fractures and the morphology of BMe. Sparing of the medial bone marrow of the femoral head was recorded together with demographic and clinical data. Progression to regional migratory osteoporosis (RMO) and postpartum cases were also recorded. Results: Our population consisted of 76.4% male and 23.6% female patients. RMO progression was recorded in 19.4% and 4 postpartum cases displayed bilateral disease. Sparing of the medial bone marrow was present at 87.7% of patients and disappeared as the disease progressed (P = 0.005). BMe was restricted within the femoral head in 11.0%, extended to the femoral neck in 40% and to the femoral shaft in 49% of the cases studied. Subchondral fractures were present at 48.7% of the hips. Conclusion: This study describes TOH patient characteristics, the MR imaging findings (BMe pattern, microfractures), their association with symptom duration and the chance of progressing to RMO

    Highlights: •Characteristics of TOH are described based on the largest series of patients in the literature. •The chance of regional migratory osteoporosis progression is estimated to be 19.4%. •The pattern of bone marrow edema with respect to symptom duration is described. •The prevalence of subchondral microfractures is high in TOH patients. •Microfractures are not complicated with avascular necrosis or articular collapse. -- Abstract: Purpose: Transient osteoporosis of the hip (TOH) presents with acute onset pain and bone marrow edema (BMe) on MR imaging. The purpose of this study is to revise the MR imaging characteristics of TOH by analyzing the data derived from 155 hip examinations. We also sought to explore the relationship between the duration of symptoms and the presence of sparing and subchondral fractures. Materials and methods: MR images of 155 hips (141 TOH patients) were retrospectively evaluated for the presence of insufficiency fractures and the morphology of BMe. Sparing of the medial bone marrow of the femoral head was recorded together with demographic and clinical data. Progression to regional migratory osteoporosis (RMO) and postpartum cases were also recorded. Results: Our population consisted of 76.4% male and 23.6% female patients. RMO progression was recorded in 19.4% and 4 postpartum cases displayed bilateral disease. Sparing of the medial bone marrow was present at 87.7% of patients and disappeared as the disease progressed (P = 0.005). BMe was restricted within the femoral head in 11.0%, extended to the femoral neck in 40% and to the femoral shaft in 49% of the cases studied. Subchondral fractures were present at 48.7% of the hips. Conclusion: This study describes TOH patient characteristics, the MR imaging findings (BMe pattern, microfractures), their association with symptom duration and the chance of progressing to RMO.

  5. Comparison of radiographic and radionuclide hip arthrography in determination of femoral component loosening of hip arthroplasties

    Radiographic examination of a patient experiencing pain following total hip arthroplasty is an important step in the systematic approach to evaluating component loosening, even though the information yielded is often equivocal and nondiagnostic in assessing component loosening. The radiographic criteria for loosening are especially difficult to assess following revision surgery, for radiolucent lines frequently exist at the bone-cement interface immediately following implantation. The advent of noncemented hip prostheses poses another problem: the routinely noted disruption of bone-cement of prosthesis-cement interfaces is not present with uncemented prostheses. As the criteria for loosening of the noncemented prostheses are still evolving, plain radiographic examination is frequently nondiagnostic. Femoral component loosening is difficult to detect with standard contrast arthrography because the bone, metal, surrounding radiopaque cement and contrast agents have similar or identical radiographic appearances. In contrast arthrography, if the prosthesis is loose the injected agent opacifies the radiolucent zone encircling the prosthesis or cement mangle. Because of the similarity in the appearances of these agents and the surrounding structures on x-ray films, interpretation is difficult. The inclusion of subtraction techniques in routine contrast arthrography has improved its accuracy; however, these techniques require special equipment and demand precise patient positioning. The purpose of this study is to introduce a new form of hip arthrography using a radionuclide agent in place of the contrast agent. A comparison of the results using these two techniques is presented

    -joint degeneration and dysplasia. Sequential body mass index (BMI) measurements from 1976 to 1992, age, exposure to daily lifting and hip dysplasia were entered into logistic regression analyses. The prevalence of hip dysplasia ranged from 5.4% to 12.8% depending on the radiographical index used. Radiological hip OA...... prevalence was 1.0--2.5% in subjects <60 years of age and 4.4--5.3% in subjects >or=60 years of age. While radiological OA was significantly influenced by hip dysplasia in men and hip dysplasia and age in women, the risk of THR being performed was only influenced by BMI assessed in 1976. Hip......We investigated the radiological and epidemiological data of 4,151 subjects followed up from 1976 to 2003 to determine individual risk factors for hip osteoarthritis (OA), hip pain and/or treatment by total hip replacement (THR).

    2010-04-01

    We investigated the incidence, risk factors and outcome of acute renal dysfunction (ARD) in patients with a fractured neck of femur. 170 consecutive patients were prospectively included in the Scottish Hip Fracture Audit database and retrospectively analysed. Historically, lack of consensus definition has hindered accurate reporting of ARD. ARD was defined using the 'RIFLE' criteria. 27 patients (16%) developed ARD. Risk factors were male sex, vascular disease, hypertension, diabetes, chronic kidney disease and pre-morbid use of nephrotoxic medications (pARD group 19%, 22% and 41% respectively, versus 0%, 4% and 13% in the non-ARD group (pARD group. Pre- and post-operative complications were 12 and 5 times more frequent respectively in the ARD group (p<0.01). Awareness of risk factors and serial measurements of renal function allow early identification and focused monitoring of these patients. PMID:19729159

    1992-01-01

    Twenty-nine patients due to have a total hip replacement had their systemic systolic and segmental blood pressures measured prior to operation and 1 and 6 weeks postoperatively. No patients had signs of ischemia. The segmental blood pressure was measured at the ankle and at the toes. A significant...... drop was found in all pressures 1 week postoperatively. The decrease followed the systemic pressure and was restored to normal after 6 weeks. In a group of six patients with preoperatively decreased ankle pressure, a significant transient further decrease in the ankle-toe gradient pressure was found on...... the operated side. None of the patients had symptoms from the lowered pressure. We conclude that in patients without signs of ischemia, the postoperative segmental pressure decrease is reversible and therefore not dangerous....

  10. Space orientation of total hip prosthesis

    A method for in vivo determination of orientation and relation in space of components of total hip prosthesis is described. The method allows for determination of the orientation of the prosthetic components in well defined anatomic planes of the body. Furthermore the range of free motion from neutral position to the point of contact between the edge of the acetabular opening and the neck of the femoral component can be determined in various directions. To assess the accuracy of the calculations a phantom prosthesis was studied in nine different positions and the measurements of the space oriented parameters according to the present method correlated to measurements of the same parameters according to Selvik's stereophotogrammetric method. Good correlation ws found. The role of prosthetic malpositioning and component interaction evaluated with the present method in the development of prosthetic loosening and displacement is discussed.

  11. Toe scratches cause scabby hip syndrome lesions.

    Hargis, B M; Moore, R W; Sams, A R

    1989-08-01

    Scabs and scratches in the hip region of chicken carcasses have become the single most common cause of downgrading and required trimming at processing in some areas of the United States. Repeatable correlations with microbiological agents, environment, and nutrition have not been observed. The present report provides evidence that scabs and scratches, present at processing, are the result of injuries inflicted by toenails of birds as they climb on one another. Onychectomy (removal of approximately two-thirds of the distal phalanx) of all four digits of each foot prior to chick placement resulted in 3.7 and 4.8-fold reduction in subjective lesion scores and 7 to 10-fold increases in the percentage of USDA Grade A carcasses at a commercial processing plant.

    BACKGROUND: Transfusion with red blood cells (RBC) may be needed during hip revision surgery but the appropriate haemoglobin concentration (Hb) threshold for transfusion has not been well established. We hypothesized that a higher transfusion threshold would improve ambulation after hip revision...... patients received RBC. CONCLUSIONS: A Hb transfusion threshold of 8.9 g/dL was associated with a statistically significantly faster TUG after hip revision surgery compared to a threshold of 7.3 g/dL but the clinical importance is questionable and the groups did not differ in Hb at the time of testing....

  15. Hip dysplasia in the cat: a report of three cases

    Hip dysplasia was diagnosed in three cats. Two were presented with a history of hindlimb lameness and the other had a history of constipation. All were confined for two weeks and showed considerable clinical improvement. At follow-up examination the cats were free of clinical signs despite the deterioration in the radiological appearance of their hips. Luxation or subluxation of the hips, insufficient development of the craniolateral acetabular edges, loss of the arched shape of the cranial subchondral acetabular bones, shallow acetabula and secondary degenerative changes on the femoral heads and necks were the main radiological findings in the affected cats

    One of the factors that contribute to the quality of total hip prostheses is the degree of accuracy in the manufacturing of the joint surfaces. The dimensional control of joint components is important because of its direct influence on the durability and, consequently, in the patients’ life quality. This work presents studies on the form and roughness of orthopedic hip prostheses marketed in Brazil. The results provide data for quality control of the surfaces of the femoral heads and acetabular components of hip prostheses and indicate the need of improvement in the procedures used to this control.

    2009-01-01

    Full Text Available Background: The best method of treating intractable hip pain in an unsalvageable hip joint in a child is still a subject open to debate. We believe that hip arthrodesis in such patients provides a painless and stable hip for most activities of daily living in our challenging rural terrain. Therefore, we conducted this study to assess the functional ability of children with painful hip arthrosis treated by arthrodesis of the hip. Materials and Methods: A retrospective evaluation of 28 children (out of 35 who had an arthrodesis of the hip performed between 1994 and 2008 was carried out. The average age was 14 years, with 12 males and 16 females. There was involvement of the right hip in 13 and left in 15 cases. The average duration of follow-up was 4.87 years. The preferred position of the hip for arthrodesis was 20-30° of flexion, neutral abduction-adduction, and neutral rotation, irrespective of the method of fixation. Results: The average duration of clinical and radiological arthrodesis was found to be 4 months (2-6 months. At the last follow-up, all patients were painfree and had good ambulatory capacity. The average Modified Harris Hip Score increased from 53 to 84 and the average post-surgical limb length discrepancy was 1.3 cm, which was well tolerated in all cases. Patients, however, had difficulty in squatting and had to modify their posture for foot care, putting on shoes, etc. Also, some patients complained of ipsilateral knee, contralateral hip, or low back pain with prolonged activity, but this was not severe enough to restrict activity except in one case that was known to have juvenile rheumatoid arthritis and needed ambulatory aid. Conclusion: In an environment where pathology generally presents very late and often in a dramatic manner, where the patient′s socioeconomic status, understanding, compliance, and the logistics of follow-up are consistently a challenge in management, hip arthrodesis has been an important procedure for

    To determine the usefulness of MR imaging for differentiation between infectious and non-infectious bursitis. MR images of 16 patients (18 lesions) in whom bursitis around the hip had been diagnosed were analyzed for homogeneity of the bursa, the presence of septation, the enhancement pattern, and associated findings. Clinical data (symptoms and signs, laboratory data, aspiration of the bursa, and surgical findings) were available for correlation. The location of bursitis was trochanteric (n=3D9), ischiogluteal (n=3D5), iliopsoas (n=3D3), or ischiotrochanteric (n=3D1). Etiologies included infection in seven cases (3 pyogenic; 4 tuberculous) and noninfection in 11 (6 inflammation; 3 hemorrhage; 2 metabolic disease). In seven patients with infectious bursitis, T1-weighted enhanced image revealed thick rim enhancement of the bursa (n=3D7) association with changes in bone marrow signal intensity (n=3D2), bone erosion (n=3D2), and cellulitis (n=3D1). Of 11 cases of noninfectious bursitis, three demonstrated typical signal characteristics of hematoma within the distended bursa. In six of seven patients who underwent contrast-enhancement, thick and thin peripheral enhancement of the bursa was noted. Bone erosion was found in one case of tuberculous bursitis and two of metabolic disease. Internal septation (n=3D4) and internal debris (n=3D3) were found in both infected and noninfected patients. MR imaging plays an important role in the diagnosis of bursitis around the hip. MR findings of thick rim enhancement, associated cellulitis, and changes in bone marrow signal intensity are suggestive of infectious bursitis.=20.

  7. From "They" Science to "Our" Science: Hip Hop Epistemology in STEAM Education

    Dolberry, Maurice E.

    Hip hop has moved from being considered a type of music into being understood as a culture in which a prominent type of music originates. Hip hop culture has a philosophy and epistemological constructs as well. This study analyzed those constructs to determine how conceptions of science factor in hip hop worldviews. Pedagogical models in culturally responsive teaching and Science, Technology, Engineering, Arts, and Mathematics (STEAM) education were also examined to discern their philosophical connections with hip hop culture. These connections were used to create two theoretical models. The first one, Hip Hop Science, described how scientific thought functions in hip hop culture. The second model, Hip Hop STEAM Pedagogy, proposes how hip hop culture can inform STEAM teaching practices. The study began by using Critical Race Theory to create a theoretical framework proposing how the two theoretical models could be derived from the philosophical and pedagogical concepts. Content analysis and narrative inquiry were used to analyze data collected from scholarly texts, hip hop songs, and interviews with hip hop-responsive educators. The data from these sources were used initially to assess the adequacy of the proposed theoretical framework, and subsequently to improve its viability. Four overlapping themes emerged from the data analyses, including hip hop-resistance to formal education; how hip hop culture informs pedagogical practice in hip hop-responsive classrooms; conceptions of knowledge and reality that shape how hip hoppers conduct scientific inquiry; and hip hop-based philosophies of effective teaching for hip hoppers as a marginalized cultural group. The findings indicate that there are unique connections between hip hop epistemology, sciencemindedness, and pedagogical practices in STEAM education. The revised theoretical framework clarified the nature of these connections, and supported claims from prior research that hip hop culture provides viable sites of

    Highlights: • MR is the preferred imaging modality for diagnosing acetabular labral tears. • The diagnostic performance of MR arthrography are superior than conventional hip MR. • The hip MR arthrography is recommended for diagnosing acetabular labral lesions. - Abstract: Objective: To evaluate the value of hip MR for diagnosing acetabular labrum tears, and to further compare the diagnostic performances of conventional MR with MR arthrography in acetabular labrum tears. Methods: 90 patients undergoing both hip MR examination and subsequent hip arthroscopy were retrospectively evaluated. Of these patients, 34 accepted both conventional MR and MR arthrography; while the other 56 only underwent conventional MR examination. All hip MR images were independently reviewed by two radiologists, and further compared with the results of hip arthroscopy. Results: 59 of 90 patients were confirmed with acetabular labral tears by hip arthroscopy and 31 without tears. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of conventional MR for evaluating the acetabular labral tears were 61.0%, 77.4%, 83.7% and 51.1% (radiologist A), and 66.1%, 74.2%, 82.9% and 53.4% (radiologist B), respectively, with good consistency between the two observers (K = 0.645). The sensitivity, specificity, PPV and NPV of MR arthrography for assessing the acetabular labral tears were 90.5%, 84.6%, 90.5% and 84.6% (radiologist A), and 95.2%, 84.6%, 90.9% and 91.7% (radiologist B), respectively, with excellent good consistency between the two observers (K = 0.810). The sensitivity and NPV of MR arthrography for diagnosing the acetabular labral tears were significantly higher than those of conventional MR (both P < 0.05). Conclusion: Hip MR arthrography is a reliable evaluation modality for diagnosing the acetabular labral tears, and its diagnostic performance is superior to that of conventional MR at 3.0 T.

    2005-01-01

    In a longitudinal case-control study, we followed 81 subjects with dysplasia of the hip and 136 control subjects without dysplasia for ten years assessing radiological evidence of degeneration of the hip at admission and follow-up. There were no cases of subluxation in the group with dysplasia....... Neither subjects with dysplasia nor controls had radiological signs of ongoing degenerative disease at admission. The primary radiological discriminator of degeneration of the hip was a change in the minimum joint space width over time. There were no significant differences between these with dysplasia...... and controls in regard to age, body mass index or occupational exposure to daily repeated lifting at admission.We found no significant differences in the reduction of the joint space width at follow-up between subjects with dysplasia and the control subjects nor in self-reported pain in the hip.

  1. Hip arthroplasty. Part 1: prosthesis terminology and classification

    Hip arthroplasty is an extremely common orthopaedic procedure and there is a wide array of implants that are in current use in the UK. The follow-up of patients who have undergone insertion of a hip prosthesis is shifting from a consultant-lead hospital service towards primary care. As this change in patient care continues it becomes increasingly important that an accurate description of the radiographic features is communicated to the primary-care practitioner so appropriate specialist input can be triggered. This review focuses on the terminology and classification of hip prostheses. This acts as a precursor for Part 2 of this series, which describes the normal and abnormal radiographic findings following hip prosthesis insertion.

  8. CONGENITAL DISLOCATION OF RIGHT HIP JOINT: IMPORTANCE OF DYNAMIC ASSESSMENT

    Pranita viveki

    2014-11-01

    Full Text Available Congenital Dislocation of Hip (CDH, is one of the most common congenital diseases in the orthopedic field. It is also known as Developmental Dysplasia of Hip. The condition can be diagnosed by clinical, ultrasonographic and radiological examination. Here we are reporting two days old male baby with congenital dislocation of right hip joint. The goal of treatment is to obtain a reduction to provide an optimal environment for femoral head and acetabular development. Early diagnosis is the most crucial aspect of the treatment of children with congenital dislocation of hip. If dislocation remains undiagnosed or neglected, the secondary pathological changes take place. Education of primary care colleagues, in making the diagnosis and prompt referral for management is recommended.

  12. [Pavlik's method in developmental dysplasia of the hip].

    Bialik, Viktor

    2007-01-01

    One of the worst complications following treatment of developmental dysplasia of the hip is avascular necrosis. In the first half of the 20th century, the incidence of this problem reached up to 30% of treated children. To avoid this complication, Arnold Pavlik developed a new method in the late 1940s and called it a dynamic approach to treatment, which was based on the ingenious idea that the hip is an organ of movements and needs movement to be healed. Healing is accomplished by using stirrups as an aid to attaining flexion of the hips and knees, whereby the child achieves a normal hip nonviolently by himself. Pavlik's method spread slowly throughout the world and this literature review points out problems with this method, and summarizes the rates of success achieved and avascular necrosis reported by various authors.

    Full Text Available Improved hip kinematics and bone preservation have been reported after resurfacing total hip replacement (THRS. On the other hand, hip kinematics with standard total hip replacement (THR is optimized with large diameter femoral heads (BFH-THR. The purpose of this study is to evaluate the functional outcomes of THRS and BFH-THR and correlate these results to bone preservation or the large femoral heads. Thirty-one patients were included in the study. Gait speed, postural balance, proprioception and overall performance. Our results demonstrated a non-statistically significant improvement in gait, postural balance and proprioception in the THRS confronting to BFH-THR group. THRS provide identical outcomes to traditional BFH-THR. The THRS choice as bone preserving procedure in younger patients is still to be evaluated.

  6. Lower-limb valgus deformity associated with developmental hip dysplasia

    GUO Sheng-jie; ZHOU Yi-xin; YANG De-jin; YANG Xu-cheng

    2012-01-01

    Background Treating developmental dysplasia of the hip is often challenging.The difficulties include not only the hip surgery itself but also the treatment of the associated lower-limb valgus deformity However,there have been very few studies on such deformity in patients with developmental hip dysplasia.In this study,we investigated the prevalence and severity of lower-limb valgus deformity,along with the relationship between the severity ef valgus deformity and mechanical alterations of the hip or the ipsilateral knee.Methods Two hundred and six affected lower limbs of 116 adult patients with untreated developmental dysplasia of the hip were included in the study,grouped according to the severity of hip dysplasia.Each study participant's radiographs were measured to quantitatively evaluate the mechanical axis deviation of the lower limb,and further to evaluate the prevalence and severity of the lower-limb valgus deformity.Some mechanical alterations of the hip and the ipsilateral knee were also measured on the radiographs.Results Of the affected lower limbs,14.1% had valgus deformities.Study participants with Crowe typeⅢ?hip dysplasiahad the most severe deformity and the highest prevalence of deformity.Severity of valgus deformity had a strong positive correlation with the lateral migration of the femoral head but not with the superior migration.A decreased lateral distal femoral angle contributed to the lower-limb valgus deformity,and the lateral distal femoral angle had a strong negative correlation with the severity of valgus deformity.Conclusions Hip dysplasia is commonly associated with lower-limb valgus deformity,and the severity of the lower-limb valgus deformity is mostly affected by lateral migration but not superior migration of the femoral head.The valgus deformity may originate mainly in the distal femur,in addition to the hip joint itself.These findings can be taken into account when planning to treat the patients with hip dysplasia.

  7. Large head metal-on-metal cementless total hip arthroplasty versus 28mm metal-on-polyethylene cementless total hip arthroplasty: design of a randomized controlled trial

    2008-01-01

    Abstract Background Osteoarthritis of the hip is successfully treated by total hip arthroplasty with metal-on-polyethylene articulation. Polyethylene wear debris can however lead to osteolysis, aseptic loosening and failure of the implant. Large head metal-on-metal total hip arthroplasty may overcome polyethylene wear induced prosthetic failure, but can increase systemic cobalt and chromium ion concentrations. The objective of this study is to compare two cementless total hip arthroplasties: ...

  9. Sonographic guidance for infant hip reduction under anesthesia

    An initial attempt to reduce a hip dislocation in a 15-month-old by palpation under general anesthesia led to the subsequent discovery of a posterior subluxation by CT. During the second attempt, sonographic guidance in the operating room was used to show concentric reduction both before and after the application of a spica cast. Successful reduction was later confirmed by CT. Imaging by real-time sonography can be useful in monitoring infant hip reduction. (orig.)

    2004-03-01

    Full Text Available Hip fracture, the most dramatic complication of osteoporosis, constitutes a serious health problem of the elderly, with great socioeconomic consequences. Hip fracture epidemiology has been studied by many investigators. Until now, there are no reported studies in Iran regarding this issue. We studied hip fractures that occurred in Iran in 2003 and compared the findings with those of other countries. Data used were obtained from the Iranian Multicenter Study on Accidental Injuries, a large-scale population-based study conducted in 9 provinces across the country. The study was conducted by the Ministry of Health and Medical Education and continued for 135 days (4.5 months in all centers, beginning in a date between 15 June 2003 and 15 July 2003 for each center. A total of 1482 new cases of hip fracture (1079 male, 403 female were recorded during the study period. The crude annual incidence of hip fracture (per 100000 person-years was 59.8 in men and 23.5 in women. The incidence rates increased exponentially after the age of 60 in both genders and nearly tripled after each decade. In comparison with hip fracture incidence rates of other countries, Iranian rates are considerably lower than other Asian, European, and American countries. The reasons for this low incidence rate remain uncertain. With increase in life span, rapid economic development and aging of the population, hip fracture will become a major health problem in Iran and studies are needed to increase awareness of osteoporosis and to monitor the epidemiology of hip fractures.

The purpose of this biomechanical study was to determin...

  2. Effect of increased pushoff during gait on hip joint forces.

    Lewis, Cara L; Garibay, Erin J

    2015-01-01

    Anterior acetabular labral tears and anterior hip pain may result from high anteriorly directed forces from the femur on the acetabulum. While providing more pushoff is known to decrease sagittal plane hip moments, it is unknown if this gait modification also decreases hip joint forces. The purpose of this study was to determine if increasing pushoff decreases hip joint forces. Nine healthy subjects walked on an instrumented force treadmill at 1.25 m/s under two walking conditions. For the natural condition, subjects were instructed to walk as they normally would. For the increased pushoff condition, subjects were instructed to "push more with your foot when you walk". We collected motion data of markers placed on the subjects' trunk and lower extremities to capture trunk and leg kinematics and ground reaction force data to determine joint moments. Data were processed in Visual3D to produce the inverse kinematics and model scaling files. In OpenSim, the generic gait model (Gait2392) was scaled to the subject, and hip joint forces were calculated for the femur on the acetabulum after computing the muscle activations necessary to reproduce the experimental data. The instruction to "push more with your foot when you walk" reduced the maximum hip flexion and extension moment compared to the natural condition. The average reduction in the hip joint forces were 12.5%, 3.2% and 9.6% in the anterior, superior and medial directions respectively and 2.3% for the net resultant force. Increasing pushoff may be an effective gait modification for people with anterior hip pain. PMID:25468661

Higher than anticipated early revision rates have been reported by several joint registries. Failed MOM hips present with a spectrum of symptoms and findings and traditional methods of failure must be considered in addition to the failure modes that appear to be unique to the MOM bearing couple. Metal hypersens...

  12. Effect of Posture on Hip Angles and Moments during Gait

    Lewis, Cara L.; Sahrmann, Shirley A.

    2014-01-01

    Anterior hip pain is common in young, active adults. Clinically, we have noted that patients with anterior hip pain often walk in a swayback posture, and that their pain is reduced when the posture is corrected. The purpose of this study was to investigate a potential mechanism for the reduction in pain by testing the effect of posture on movement patterns and internal moments during gait in healthy subjects. Fifteen subjects were instructed to walk while maintaining three postures: 1) natura...

    Woo, Daniel

    2013-01-01

    This paper examines Hip Hop as a social space with mixed implications for contemporary Asian-Black relations. Through establishing common grounds based on mutual interests and shared cultural identities, Hip Hop bears the potential to facilitate meaningful cross-racial exchange. Concurrently it may exacerbate existing tensions, shaped by dominant cultural politics that have situated these groups in tandem. The growing emergence of Asian American rappers has brought accusations of cultural mis...

    1985-01-01

    Limp and pain are common findings about the hip and knee in growing children. Epiphyseal growth peculiarities in children account for many of the specific disease entities. Simple but specific physical examination and mandatory simple X-rays will virtually always give or exclude a diagnosis. problems about the hip are usually serious, for example Legg-Perthes, slipped epiphysis and septic arthritis. Most childhood knee problems are annoying but not serious. Chondromalacia patellae and Osgood-...

    2016-01-01

    Due to the increasing elderly population, the prevalence of osteoporotic hip fractures in Japanese patients continues to rise. It is well established that patients with either hip fracture or both symptomatic and asymptomatic morphometric vertebral compression fracture (VCF) have a poor health prognosis compared with the general population. The purpose of this study was to retrospectively investigate vertebral fracture rates among patients with hip fracture and their influence on mortality. We examined 182 cases of osteoporotic hip fracture in patients admitted to our institution between January 2009 and May 2011. The average age at the time of fracture was 85 years. Radiographs of the lumbar spine were obtained from all of the participants and the lateral spinal radiographs were examined for evidence of VCF. The patients were classified into two groups, those with VCF and those without. A VCF was identified in approximately 78 % of the patients. The mortality rate 1 year after the hip fracture was approximately 22 % and it was significantly higher in patients with VCF. Through multivariate statistics we found that VCF, post-operative complication, loss of ambulation after operation and medication for osteoporosis were statistically significant. In other words, VCF, post-operative complication and loss of ambulation were considered to be poor prognostic factors and medication for osteoporosis was likely to improve the prognosis. We concluded that the risk of mortality after hip fracture is significantly greater in patients who also have VCF compared to patients without VCF, and that medication for osteoporosis is likely to improve prognosis.

  16. Childhood idiopathic chondrolysis of the hip: MRI features

    Childhood idiopathic chondrolysis of the hip (ICH) causes progressive destruction of the articular cartilage of the hip joint with associated bone remodelling. The MRI features of this disease have not previously been described. To document the MRI features of childhood ICH and determine which features may help distinguish ICH from other causes of hip joint destruction in the paediatric population. A retrospective review of the MRI examinations of children with clinically diagnosed ICH. All children had undergone synovial biopsy and/or joint aspiration with plain hip radiography to exclude causes of secondary chondrolysis. Ten MRI examinations were performed on six children. Cartilage loss, small hip joint effusions, bone remodelling and significant regional muscle wasting were seen in all children. Cartilage loss was most severe in the central part of the joint. Synovial enhancement was not a constant feature of ICH. Serial imaging in three children showed disease progression. MRI in ICH clearly demonstrates cartilage loss and enables delineation of bone and muscle abnormalities. It is helpful in the differential diagnosis of hip joint disease in children and may provide further information on the progression and aetiology of ICH. (orig.)

    2004-03-01

    Background: Various qualitative and quantitative radiological geometrical parameters can be of great help when assessing dysplasia of the hip joint and in understanding developmental processes of the infant hip. There are few data on the normal values of the hip joint at different ages. Objective: To perform radiographic measurements on hip joints considered to be anatomically normal and to provide data for each age group, thus describing features of the radiographic development of the hip. Materials and methods: Radiographs were examined from 355 children (age 0-16 years) undergoing examination for scoliosis (long film), urography or plain abdominal radiography. Qualitative and quantitative signs were observed and measured, focusing on the Hilgenreiner, Wiberg and Idelberger angles and the decentric distance. Results: Before the age of 9 years measurable data from neighbouring age groups differed significantly, indicating typical radiological changes of the joint. For the same age range, qualitative changes could also be observed. After 9 years of age, radiological development of the normal hip joint during childhood is much slower. (orig.)

  19. Bilateral inferior dislocation of the hip-a case report

    Bhagwat Kishan R

    2012-04-01

    Full Text Available 【Abstract】Inferior dislocation of the hip is the ra-rest type in hip dislocation. Very few cases have been re-ported in the anglophonic literature, most of which involved the pediatric age group. Surprisingly, we came across a 30-year-old patient with a bilateral inferior hip dislocation. He had sustained a road traffic accident and the attitude of both hip joints was flexion and abduction. The diagnosis was confirmed by radiographs which revealed the long axis of the femur at an angle of 110 (right degrees and 100 (left degrees respectively away from the axis. Closed reduction under sedation was successfully performed. Skin traction for a period of 6 weeks was advised and the follow-up re-vealed an excellent result. We present the details of this case, the first of its kind along with a review of the literature, discussing the various modes and mechanisms of injury inducing inferior dislocation of the hip. Key words: Hip dislocation; Joints; Femur

  20. Impact of hip prosthesis on dose distribution of pelvic radiotherapy

    Objective: To study the scattering effect of Co-Cr-Mo hip prosthesis which was high Z material for patients undergoing pelvic irradiation. Methods: The hip prosthesis was set in water phantom (30 cm x 30 cm x 30 cm), determining points were chosen on the entrance side of both 6 MV and 10 MV beams at the distance of 0.5 cm, 1.0 cm, 2.0 cm to the hip prosthesis, and also on the exit side of both 6 MV and 10 MV beams at the distance of 3.0 cm, 5.0 cm, 7.0 cm to the hip prostheses. Dose behind the hip prosthesis at depths of 5.0 cm and 10.0 cm for 6 MV and 10 MV beams are also measured. Results: The dose deviation on the beams' entrance side is between 0 to 5.0%, the backscatter effect was more obviously with the higher energy beam. The dose deviation on the beams' exit side was between 21.6%-30.8%. With the same field size and depth, dose deviation becomes smaller when the beam energy was higher; while with the same energy and depth, dose deviation becomes smaller when the field size was bigger. Dose profiles behind the head of the hip prosthesis indicate obvious attenuation of the beam. Conclusions: Beam arrangements that avoid the prosthesis should be considered first or we should at least reduce the weight of the beam that pass through the prosthesis. (authors)

    Bigaard, J; Frederiksen, K; Tjønneland, A; Thomsen, B L; Overvad, K; Heitmann, B L; Sørensen, T I A

    2004-01-01

    OBJECTIVE: To investigate whether waist and hip circumferences, in addition to body mass index (BMI), are related to all-cause mortality. We studied these associations and tested the usefulness of the waist-to-hip ratio for mortality prediction. DESIGN: A Danish prospective cohort study with data...... inverse for both men and women, but only after adjustment for waist circumference, or BMI, or both. The mortality rate ratios of mutually adjusted waist and hip circumferences were 0.63 (95% CI: 0.56, 0.71), and 0.70 (95% CI: 0.63, 0.79) times higher per 10% larger hip circumference in men and women......, respectively, and 1.45 (95% CI: 1.34, 1.57) and 1.22 (95% CI: 1.14, 1.31) times higher per 10% larger waist circumference. The adequacy of the waist-to-hip ratio as a substitute for separate measurements of waist and hip circumferences depended on which other variables the analysis was adjusted for, indicating...

  2. Total hip arthroplasty in paralytic dislocation from poliomyelitis.

    Laguna, Rafael; Barrientos, Jesús

    2008-02-01

    This article presents a case of a patient with degenerative hip disease in paralytic dislocation by poliomyelitis. Poliomyelitis is an acute infection disease caused by a group of neurotrophic viruses, which has a special affinity by the anterior horns cells of the spinal cord and for certain motor nuclei of the brain stem. Paralysis is a flaccid type and characteristically paralysis is asymmetrical. It is said that the joints of the affected limb by poliomyelitis are protected from the development of osteoarthritis. Hip dislocation in poliomyelitis is an acquired deformity caused by flaccid paralysis and the resulting muscular imbalance. In young children, when the gluteus maximus and medius muscles are paralyzed and the hip flexors and adductors are of normal strength, eventual luxation of the hip is almost inevitable. Hip osteoarthritis in a limb with poliomyelitis is an unusual entity because these limbs do not support excessive loads. In patients who present with the residual effects of poliomyelitis including degenerative disease and hip dysplastic, surgery is one of the most difficult challenges faced by reconstructive surgeons. In such cases, surgeons should attempt to optimize the component position and choice, surgical approach, and soft tissue tensioning because stability of the prosthesis can be problematic.

    2008-01-01

    Full Text Available Background: Total hip athroplasty with the anterior surgical approach is advised because the dissection is entirely within intermuscular planes. In this report we describe a minimally invasive technique of anterior total hip arthroplasty, with the early outcomes. Materials and Methods: The technique of minimally invasive total hip arthroplasty with anterior approach (Smith-Petersen is described. We reviewed data on 100 consecutive patients who underwent anterior total hip arthroplasty with uncemented components. Mean patient age was 61 years (range 33-91. Mean patience BMI 29.8 (range 18.1-51.8. Results: Minumum follow up duration is 10 months. The mean duration of surgery was 53 min (range 34-87 with mean blood loss 185 cc (range 65-630, and the mean incision length was 10.4 cm. Clinical and radiographic outcomes were similar to historical outcomes of standard total hip arthroplasty. Conclusions: With proper surgeon training, minimally invasive total hip replacement with the anterior surgical interval is safe and efficacious.

  4. Injuries about the hip in the adolescent athlete.

    Kovacevic, David; Mariscalco, Michael; Goodwin, Ryan C

    2011-03-01

    Athletic injuries in or around the hip in the adolescent athlete encompass possible causes such as a single, traumatic event to those of repetitive microtrauma. The injuries may involve the bone or the soft tissues, with former involving the epiphysis, apophysis, metaphysis, or diaphysis, whereas the latter includes muscles and tendons. With the improvements in surgical technique and instrumentation for hip arthroscopy and the development of magnetic resonance arthrography, clinicians have been able to diagnose and treat labral tears, hip instability, snapping hip, loose bodies, chondral injuries, and femoroacetabular impingement. The clinician needs to consider acquired conditions that may have coincidentally become apparent as a result of the adolescent's participation in an organized sports program. These include slipped capital femoral epiphysis, Legg-Calvé-Perthes disease, and pathologic lesions and fractures. This study reviews the more common acute and chronic overuse injuries in or around the hip in the adolescent athlete and discusses hip injury prevention in this active patient population.

  5. Primary synovial osteochondromatosis of the hip: extracapsular patterns of spread

    To identify patterns of extracapsular extension of synovial osteochondromatosis of the hip. Seven cases of synovial osteochondromatosis of the hip were retrospectively reviewed. Imaging performed included conventional radiography (n=7), arthrography (n=1), CT (n=3) and MR imaging (n=3). Disease extent on imaging was assessed for each patient and the presence of intra-articular effusion, capsular abnormality and osteochondral bodies recorded. The presence and distribution of extra-articular spread was also assessed and correlated with the surgical findings. In all cases diagnosis was confirmed by biopsy, with all patients undergoing tumor resection with or without synovectomy. In five cases (5/7) disease extended beyond the hip capsule, while the remaining two cases (2/7) were confined to the hip joint. These findings were confirmed at surgery. Two distinct patterns of extracapsular spread were identified. The first pattern, noted in three cases, involved tumor extension along iliopsoas. The second pattern, noted in five cases, involved tumor extension along the obturator externus fat plane. In three cases both patterns were present. Extra-articular spread of synovial osteochondromatosis is common. Patterns of extra-articular spread may be predictable based on involvement of recognized periarticular bursae of the hip joint. Bursal patterns of extra-articular spread include extension into the iliopsoas bursa as well as communication along the obturator externus bursa of the hip. (orig.)

  6. Lower limb length and offset in total hip arthroplasty.

    Flecher, X; Ollivier, M; Argenson, J N

    2016-02-01

    Restoration of normal hip biomechanics is a key goal of total hip arthroplasty (THA) and favorably affects functional recovery. Furthermore, a major concern for both the surgeon and the patient is preservation or restoration of limb length equality, which must be achieved without compromising the stability of the prosthesis. Here, definitions are given for anatomic and functional limb length discrepancies and for femoral and hip offset, determined taking anteversion into account. Data on the influence of operated-limb length and offset on patient satisfaction, hip function, and prosthesis survival after THA are reviewed. Errors may adversely impact function, quality of life, and prosthetic survival and may also generate conflicts between the surgeon and patient. Surgeons rely on two- or three-dimensional preoperative templating and on intraoperative landmarks to manage offset and length. Accuracy can be improved by using computer-assisted planning or surgery and the more recently introduced EOS imaging system. The prosthetic's armamentarium now includes varus-aligned and lateralized implants, as well as implants with modular or custom-made necks, which allow restoration of the normal hip geometry, most notably in patients with coxa vara or coxa valga. Femoral anteversion must also receive careful attention. The most common errors are limb lengthening and a decrease in hip offset. When symptoms are caused by an error in length and/or offset, revision arthroplasty may deserve consideration. PMID:26797005

  7. PRIMARY CEMENTLESS TOTAL HIP ARTHROPLASTY IN ANKYLOSING SPONDYLITIS

    Nageshwara Rao

    2015-12-01

    Full Text Available INTRODUCTION Ankylosing Spondylitis (AS, family of Spondyloarthritides (SpAs, is a chronic inflammatory disease affecting the axial skeleton, the entheses and occasionally the peripheral joints. The shoulders and hips are considered axial joints and involvement occurs in up to 50% of patients and is more common than involvement of the more distal joints. Aim of our study is to evaluate outcome of Cementless Total Hip Arthroplasty (THA in ankylosing spondylitis. MATERIALS AND METHODS We prospectively and retrospectively reviewed 27 hips in 20 patients who underwent cementless THA between 2007-2013. Mean age of patient was 31.5 years. We analysed demographic data, preoperative deformity, Harris Hip Score, ambulatory status, need for walking aids. RESULTS All patients experienced significant improvement in function, range of motion, posture and ambulation. Postoperative Harris Hip Score improved from 18.95 to 89.35; 90% are completely pain free, 5% have occasional discomfort and 5% have mild-to-moderate pain. CONCLUSION Cementless THA for deformed hips in young patients with AS is worthwhile surgical intervention, as it increases the mobility of the patient, improves the ability to sit comfortably, decrases the morbidity of the disease. However, the technically demanding nature of the procedure should not be underestimated.

    2015-12-01

    Full Text Available Normal hip range of motion (ROM is essential in running and transfer of energy from lower to upper extremities during overhead throwing. Dysfunctional hip ROM may alter lower extremity kinematics and predispose athletes to hip and groin injuries. The purpose of this study is characterize hip internal/external ROM (Arc and its effect on the risk of hip, hamstring, and groin injuries in professional baseball players. Bilateral hip internal and external ROM was measured on all baseball players (N=201 in one professional organization (major and minor league during spring training. Players were organized according to their respective positions. All injuries were documented prospectively for an entire MLB season (2010 to 2011. Data was analyzed according to position and injuries during the season. Total number of players (N=201 with an average age of 24±3.6 (range=17-37. Both pitchers (N=93 and catchers (N=22 had significantly decreased mean hip internal rotation and overall hip arc of motion compared to the positional players (N=86. Players with hip, groin, and hamstring injury also had decreased hip rotation arc when compared to the normal group. Overall, there is a correlation between decreased hip internal rotation and total arc of motion with hip, hamstring, and groin injuries.

  10. Delayed cementless total hip arthroplasty for neglected dislocation of hip combined with complex acetabular fracture and deficient bone stock

    Gavaskar Ashok S

    2012-12-01

    Full Text Available 【Abstract】Total hip arthroplasty (THA for an un-treated acetabular fracture is technically challenging and the long-term result is not so favorable. A 45-year-old fe-male patient with untreated column and comminuted poste-rior wall fracture of the acetabulum was treated in our insti-tution by reconstruction of the posterior wall using iliac strut autograft and plate stabilization of the posterior col-umn with cancellous grafting and cementless THA in a single stage. At 3 years’ follow-up, the patient was independently mobile without limb length discrepancy. Radiological evalu-ation showed well integrated components and bone grafts. No evidence of aseptic loosening or osteolysis was found. This report aims to emphasize that bony acetabular recon-struction allows the use of primary hip components, which improves prosthesis longevity and preserves bone stock for a future revision.

  11. Cell therapy of hip osteonecrosis with autologous bone marrow grafting

    Hernigou Philippe

    2009-01-01

    Full Text Available Background: One of the reasons for bone remodeling leading to an insufficient creeping substitution after osteonecrosis in the femoral head may be the small number of progenitor cells in the proximal femur and the trochanteric region. Because of this lack of progenitor cells, treatment modalities should stimulate and guide bone remodeling to sufficient creeping substitution to preserve the integrity of the femoral head. Core decompression with bone graft is used frequently in the treatment of osteonecrosis of the femoral head. In the current series, grafting was done with autologous bone marrow obtained from the iliac crest of patients operated on for early stages of osteonecrosis of the hip before collapse with the hypothesis that before stage of subchondral collapse, increasing the number of progenitor cells in the proximal femur will stimulate bone remodeling and creeping substitution and thereby improve functional outcome. Materials and Methods: Between 1990 and 2000, 342 patients (534 hips with avascular osteonecrosis at early stages (Stages I and II were treated with core decompression and autologous bone marrow grafting obtained from the iliac crest of patients operated on for osteonecrosis of the hip. The percentage of hips affected by osteonecrosis in this series of 534 hips was 19% in patients taking corticosteroids, 28% in patients with excessive alcohol intake, and 31% in patients with sickle cell disease. The mean age of the patients at the time of decompression and autologous bone marrow grafting was 39 years (range: 16-61 years. The aspirated marrow was reduced in volume by concentration and injected into the femoral head after core decompression with a small trocar. To measure the number of progenitor cells transplanted, the fibroblast colony forming unit was used as an indicator of the stroma cell activity. Results: Patients were followed up from 8 to 18 years. The outcome was determined by the changes in the Harris hip score

    2013-01-01

    The conflict thesis and the segmented assimilation theory account for two of the most significant trends in American immigration and ethnicity studies. Both of these major theoretical styles are utterly pessimistic towards interethnic relations in the United States and assimilation into African American urban culture. I have asked in this thesis if the experiences and the history of hip-hop culture can counterbalance these negative interpretations of interethnic relations. Hip-hop culture has...

  15. Two Different Total Hip Arthroplasties for Hartofilakidis Type C1 Developmental Dysplasia of Hip in Adults

    Ya-Ming Chu; Yi-Xin Zhou; Na Han; De-Jin Yang

    2016-01-01

    Background: Total hip arthroplasty (THA) in developmental dysplasia of the hip (DDH) is more complex than the normal hip, with large replacement risks and many complications.Although nonosteotomy THA is convenient to perform, femoral osteotomy shortening can avoid blood vessel and nerve traction injuries.This study aimed to compare osteotomy THA with nonosteotomy to determine reasonable options for operative management of DDH.Methods: Data on 48 DDH patients who underwent THA were analyzed retrospectively.The patients were divided into two groups: Group A 29 cases (nonosteotomy), and group B 19 cases (osteotomy).Harris and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, limb length discrepancy (LLD), radiological data on the hip, and claudication were evaluated.Data were analyzed by using paired-sample Student's t-test, independent-sample Student's t-test, and Pearson's Chi-square test;the test level was α =0.05.Results: Postoperative Harris (90.7 ± 5.1) and WOMAC scores (88.0 ± 10.6) were significantly improved compared with preoperative Harris (44.8 ± 5.7) and WOMAC scores (42.0 ± 5.3) in group A (P < 0.05).Postoperative Harris (90.4 ± 2.8) and WOMAC scores (88.2 ± 5.9) were significantly improved compared with preoperative Harris (44.4 ± 4.2) and WOMAC scores (43.2 ± 4.3) in group B (P < 0.05).One case of dislocation occurred in group A;after closed reduction, dislocation did not recur.In group A, 2 patients developed cutaneous branch injury of the femoral nerve, which spontaneously recovered without treatment.Postoperative LLD >2 cm was seen in one case in group A and five cases in group B.Postoperative claudication showed no significant difference between the two groups (P > 0.05).No patients developed infection;postoperative X-rays showed that the location of the prosthesis was satisfactory, and the surrounding bone was not dissolved.Conclusions: THA is effective and safe for DDH.For unilateral high dislocation

  16. Influence of Different Hip Joint Centre Locations on Hip and Knee Joint Kinetics and Kinematics During the Squat

    Sinclair Jonathan

    2014-12-01

    Full Text Available Identification of the hip joint centre (HJC is important in the biomechanical examination of human movement. However, there is yet to be any published information regarding the influence of different HJC locations on hip and knee joint kinetics during functional tasks. This study aimed to examine the influence of four different HJC techniques on 3- D hip and knee joint kinetics/kinematics during the squat. Hip and knee joint kinetics/kinematics of the squat were obtained from fifteen male participants using an eight camera motion capture system. The 3-D kinetics/kinematics of the squat were quantified using four hip joint centre estimation techniques. Repeated measures ANOVAs were used to compare the discrete parameters as a function of each HJC location. The results show that significant differences in joint angles and moment parameters were evident at both the hip and knee joint in the coronal and transverse planes. These observations indicate that when calculating non-sagittal joint kinetics/kinematics during the squat, researchers should carefully consider their HJC method as it may significantly affect the interpretation of their data.

  17. Adult Hip Flexion Contracture due to Neurological Disease: A New Treatment Protocol—Surgical Treatment of Neurological Hip Flexion Contracture

    Alberto Nicodemo

    2014-01-01

    Full Text Available Congenital, traumatic, or extrinsic causes can lead people to paraplegia; some of these are potentially; reversible and others are not. Paraplegia can couse hip flexion contracture and, consequently, pressure sores, scoliosis, and hyperlordosis; lumbar and groin pain are strictly correlated. Scientific literature contains many studies about children hip flexion related to neurological diseases, mainly caused by cerebral palsy; only few papers focus on this complication in adults. In this study we report our experience on surgical treatment of adult hip flexion contracture due to neurological diseases; we have tried to outline an algorithm to choose the best treatment avoiding useless or too aggressive therapies. We present 5 cases of adult hips flexion due to neurological conditions treated following our algorithm. At 1-year-follow-up all patients had a good clinical outcome in terms of hip range of motion, pain and recovery of walking if possible. In conclusion we think that this algorithm could be a good guideline to treat these complex cases even if we need to treat more patients to confirm this theory. We believe also that postoperation physiotherapy it is useful in hip motility preservation, improvement of muscular function, and walking ability recovery when possible.

  18. Total hip arthroplasty in patients with avascular necrosis of the hip. Follow-up observations on cementless and cemented operations.

    Katz, R L; Bourne, R B; Rorabeck, C H; McGee, H

    1992-08-01

    Thirty-one patients with avascular necrosis of the hip were treated by 34 total hip arthroplasties (THAs). All patients were observed prospectively with a minimum two-year follow-up evaluation (average, 46 months; range, 24-84 months). Twenty had cemented arthroplasties using contemporary cementing techniques. This included insertion of a medullary plug, cleansing of the canal with a medullary brush, pulsatile lavage irrigation, and insertion of the cement with a cement gun. In 14 hips, a cementless prosthesis was used. Patients were rated using a modified Harris hip score. Sequential postoperative roentgenograms were analyzed in each patient. The overall Harris hip score ratings were 88 in the cemented and 84 in the noncemented groups. Mechanical failure with loosening of the femoral component occurred in one patient who developed deep sepsis. Significant thigh pain occurred in four patients in the noncemented group. Previous studies in the literature have generally reported unfavorable results in patients with avascular necrosis of the hip treated with THA. Using cementless and cemented fixation with contemporary cementing techniques, improved results can be expected. A high incidence of thigh pain (29%) in the cementless group remains a problem.

  19. Effect of hip prostheses on radiotherapy dose

    A small but growing proportion of patients requiring radiotherapy for prostate cancer have one or two hip prostheses which may shadow the target and affect the dose distribution. Approximately 10 such patients are treated at the Illawarra Cancer Care Centre per year. Hence a study was undertaken to examine the accuracy of various treatment methods that involve some of the treatment fields travelling through the prosthesis. A fixed-field measurement showed a dose reduction of 52% in the shadow of the prosthesis. A Monte Carlo simulation confirmed an increase in dose on the distal surface of the prosthesis of 35%. Of more clinical relevance, however, is the dose distribution due to the overall combined field treatment. Using a power law correction benchmarked against thermoluminescent dosimeters and Gafchromic film, three different beam set-ups for patient treatment were planned and the dose variation analysed. A four-field brick technique gave a dose variation across the target volume of ± 15% whereas a dual arc technique gave a dose variation of only ± 5%. A four-field oblique technique gave a dose variation of only ± 2% across the target volume but the oblique field technique included extra dose to the rectum.

    Full Text Available The purpose of this study was to analyse a new concept of using the the minimally invasive direct anterior approach (DAA in total hip replacement (THR in combination with the leg positioner (Rotex- Table and a modified retractor system (Condor. We evaluated retrospectively the first 100 primary THR operated with the new concept between 2009 and 2010, regarding operation data, radiological and clinical outcome (HOOS. All surgeries were perfomed in a standardized operation technique including navigation. The average age of the patients was 68 years (37 to 92 years, with a mean BMI of 26.5 (17 to 43. The mean time of surgery was 80 min. (55 to 130 min. The blood loss showed an average of 511.5 mL (200 to 1000 mL. No intra-operative complications occurred. The postoperative complication rate was 6%. The HOOS increased from 43 points pre-operatively to 90 (max 100 points 3 months after surgery. The radiological analysis showed an average cup inclination of 43° and a leg length discrepancy in a range of +/- 5 mm in 99%. The presented technique led to excellent clinic results, showed low complication rates and allowed correct implant positions although manpower was saved.
