BACKGROUND: There is no consensus about the duration of post-operative immobilization in the treatment of DDH (developmental dysplasia of hip). Our aim in this study is to compare between two post-operative immobilization protocols for patients undergoing open reduction. MATERIALS AND METHODS: Thirty-eight hips in 32 patients assigned to group A were immobilized in hip spica for four weeks followed by abduction brace application which was gradually weaned through the periods of several months and 29 hips in 24 patients assigned to group B immobilized in hip spica for 12 weeks without further bracing...

Developmental dysplasia of the hip (DDH) in infants under 6 months of age is typically treated by the Pavlik harness (PH). During successful PH treatment, a subluxed/dislocated hip is spontaneously reduced into the acetabulum, and DDH undergoes self-correction. PH treatment may fail due to avascular necrosis (AVN) of the femoral head. An improved understanding of mechanical factors accounting for the success/failure of PH treatment may arise from investigating articular cartilage contact pressure (CCP) within a hip during treatment...

INTRODUCTION: Bernese-type triple pelvic osteotomy (BTPO) combines periacetabular and triple innominate osteotomy techniques. However, studies that evaluate the clinical and radiographic outcomes of BTPO are scarce. The aim of this study is to report on the clinical and radiographic outcomes of ambulatory children with developmental dysplasia of the hip (DDH) or Legg-Calvé-Perthes disease (LCPD) managed with BTPO that were older than five years of age at the time of surgery. MATERIALS AND METHODS: We retrospectively reviewed the records of 27 consecutive patients with DDH or LCPD (mean age 7...

We report 2 cases of patients with solid tumors and coagulopathy who experienced avascular necrosis (AVN) of the bone following chemotherapy. Both cases exhibited nontraumatic bilateral AVN of the femoral heads, and one also showed bilateral AVN of the humeral heads. One case had multiple thromboembolic complications, including pulmonary obstructive syndrome and paraneoplastic pain. The other showed multiple paraneoplastic syndromes, with hypercalcemia and thrombocytosis. Groin pain and claudication of the lower extremities developed and persisted...

This research focuses on femoral head wedge resection for the treatment of avascular necrosis (AVN) of the femoral head. A 9-year-old girl presented to the emergency room complaining of right hip pain that occurred after a pedestrian car accident. After 8 months of internal fixation using cannulated screws for Delbet-type 2 fracture of the femoral neck, AVN of the femoral head developed in the patient. Even though valgus-derotation-extension intertrochanteric osteotomy was performed for the treatment of AVN, it progressed further and femoral head wedge resection was performed to recover the femoral head sphericity...

INTRODUCTION: Developmental dysplasia of the hip (DDH) affects 4-6 per 1000 live births in developed countries. Effective treatment to realign the hip is necessary to avoid long-term morbidities and maximise functional outcome. Treatment options depend on patient age but typically involve hip bracing and/or reduction under general anaesthetic. Some centres also employ prereduction hip traction. Historical papers suggest traction reduces risk of avascular necrosis (AVN) femoral head and reduces requirement for open reduction...

Slipped capital femoral epiphysis (SCFE) is not frequently encountered during routine practice and diagnosis and treatment are often delayed. It is important to understand symptoms and imaging features to avoid delayed diagnosis. After the diagnosis is made correct classification of the disease is required. The classification should be based on the physeal stability in order to choose safe and effective treatment. However, surgeons should bear in mind that the assessment is challenging and actual physeal stability is not always consistent with the stability predicted by a clinical classification method...

Objective This study aimed to assess the principal risk factors that could lead to the most common long-term complications of slipped capital femoral epiphysis, such as avascular necrosis, chondrolysis, and hip impingement. Methods We conducted a single-centre, retrospective study and evaluated patients (70 patients, 81 hips) who were treated for slipped capital femoral epiphysis from 2010 to 2015 and who underwent pinning. We measured the severity of displacement radiologically using the Southwick angle. Postoperative radiographs were evaluated for the most frequent long-term complications of avascular necrosis (AVN), chondrolysis, and femoral acetabular impingement (FAI)...

The treatment of developmental dysplasia of the hip (DDH) in children remains controversial. We describe the clinical and radiological outcomes of  47 hips in 43 children treated with open surgery by one surgeon between 2004 and 2008 for DDH. The mean age at operation was 25 months (5 to 113) with a mean follow up of  89 months  (22 to 169). At the latest follow up 40 of the 45 hips where Severin grades were recordable (89%) were graded as excellent or good, Severin class I or II. Clinically significant AVN (grade II to III  according to the Kalamchi and MacEwen classification) was seen in 6  (13%) of the hips...

Osteochondromas are usually extra-articular lesions originating from the metaphysis of long bones. Intra-articular osteochondromas may also occur, causing pain and discomfort and restricting the range of motion. Osteochondromas of the femoral neck are intra-articular lesions that are difficult to access for surgical resection, particularly when located posteriorly. We herein present a rare case of an intra-articular osteochondroma involving the posteroinferior aspect of the femoral neck associated with secondary synovial osteochondromatosis (SOC) of the hip joint in a 25-year-old woman...

BACKGROUND: Developmental dysplasia of the hip (DDH) diagnosed in older postnatal children can be effectively treated by closed reduction (CR) alone. However, no prospective or comparative trial to explore the differential effectiveness of CR between non-walking and walking postnatal children has yet been reported. This study investigated the clinical and radiologic outcomes of CR in the age range of interest (12-18 months old) via a prospective trial and compared these results with those of a younger age group who also underwent CR...

BACKGROUND: Escalated BEACOPP (eBEACOPP) is an effective but fairly toxic regimen for treatment of Hodgkin lymphoma (HL). Avascular necrosis of femoral head (AVN) was previously reported to be increased in patients treated with eBEACOPP, but so far no systematic analysis of its frequency has been published. AIMS: We aimed to analyze frequency and identify possible risk factors for AVN development in patients treated with eBEACOPP. METHODS: We identified 26 patients treated with eBEACOPP for newly diagnosed high-risk advanced stage HL, 25 patients alive at the time of study...
