BACKGROUNDS: Although most displaced femoral neck fractures of young patients can be repositioned successfully by closed reduction, there are still some can not repositioned successfully by this way and open reductions are required. This type of fracture was defined as irreducible displaced femoral neck fracture in this study. The purpose of this study was to introduce a new technique using anteromedial femoral neck plate with cannulated screws fixation by open reduction for the treatment of irreducible displaced femoral neck fractures in young patients...

INTRODUCTION: Total hip replacement (THR) surgery is still evolving in Nigeria with increasing awareness as more cases are being done. This has attraction for individuals who hitherto had no solutions for their hip pathologies. These are mostly complex primary hips which present challenging technical difficulties with increased risk of complications, thus requiring detailed planning to ensure successful operation. This work aims to present the pattern of complex primary hips presenting for THR, the challenges and complications...

Femoral nerve palsy after total hip arthroplasty is an uncommon complication. We present a case report of delayed-onset femoral nerve palsy associated with iliopsoas hematoma and bursitis 10 years after primary total hip arthroplasty in a 57-year-old male patient with avascular necrosis of the femoral head. The patient visited our clinic due to swelling of the inguinal area with sudden-onset knee extension weakness. Radiologic examination at admission revealed suspicion of bursitis and hematoma on iliopsoas muscle...

A 33-year-old woman with history of HIV presented with 4 months of gradually progressing right hip pain and was found to have avascular necrosis (AVN) of both femoral heads. She had no other risk factors for AVN including sickle cell disease, systemic lupus erythematosus, prolonged steroid used or trauma. She initially failed conservative management and ultimately had bilateral hip core decompressions. After decompression therapy, the left femoral head collapsed and patient underwent a left total hip arthroplasty...

Intracapsular cuneiform osteotomy was initially introduced to restore the morphology of the proximal femur after slipped capital femoral epiphysis (SCFE). However, whether this procedure results in a higher risk of avascular necrosis (AVN) or lower incidence of cam deformity than in-situ pinning is unclear. The aim of this study was to compare the outcomes of intracapsular cuneiform osteotomy and in-situ pinning to treat SCFE in children. Twenty-three children who suffered from SCFE underwent either intracapsular cuneiform osteotomy (eight patients, eight hips) or in-situ pinning (15 patients, 18 hips) between 2006 and 2014...

The treatment of slipped capital femoral epiphysis (SCFE) in North America has seen a change over the past 15 to 20 years due to a better understanding of the blood flow supplying the femoral head, the ability to monitor the pressure/flow in real time and greater access to the deformity with the development of surgical approaches providing that access. These advances have mainly affected the treatment of the unstable SCFE to mitigate the risk of avascular necrosis but have also been utilized for the stable SCFE when severe deformity remains...

INTRODUCTION: Treatment of developmental dysplasia of hip (DDH) diagnosed after 10 years of age is extremely difficult because of the soft tissue and bone deformities. In this study, we evaluated short-term results of a single-stage procedure performed with surgical hip dislocation, femoral shortening and capsular arthroplasty. PATIENTS AND METHODS: A retrospective review of charts of five patients with DDH, older than 10 years, who underwent capsular arthroplasty at Ghurki Trust Teaching Hospital between 2013 and 2015 was performed...

Background: Kidney transplant recipients (KTRs) are at increased risk of avascular necrosis (AVN) due to bone disorder, steroid use and common comorbidities. However, knowledge on risk factors and outcomes of AVN among KTRs in the modern era of immunosuppression remains scarce. Methods: We analysed 765 KTRs between 2001 and 2013 for AVN. Cases of symptomatic AVN were diagnosed by hip X-ray, radioisotope bone scan or magnetic resonance imaging. We evaluated risk factors and clinical characteristics of AVN...

The majority of injuries during a football game are contusions, sprains and/or strains in the thigh, knee and ankle. Hip dislocations account for 2-5% of total hip dislocations, and they can be posterior or anterior. Major complications of traumatic hip dislocation include avascular necrosis of femoral head, secondary osteoarthritis, sciatic nerve injury and heterotopic ossification. On the occasion of a case of a 33-year-old football player, who suffered a posterior hip dislocation, associated with a posterior wall fracture of the acetabulum, while playing football, we review the literature and analyze the various mechanisms of injury, the possible complications and the management including surgery and rehabilitation...

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...

BACKGROUND: Previous reports on patients with developmental dysplasia of the hip (DDH) showed that the prereduced femoral head was notably smaller and more nonspherical than the intact head, with growth failure observed at the proximal posteromedial area. We evaluated the shape of the femoral head cartilage in patients with DDH before and after reduction, with size and sphericity assessed using 3-dimensional (3D) magnetic resonance imaging (MRI). METHODS: We studied 10 patients with unilateral DDH (all female) who underwent closed reduction...

There is a lack of high quality evidence available to guide clinical practice in the treatment and management of developmental dysplasia of the hip (DDH). Evidence has been limited by persistent confusion on diagnostic and classification terminology, variability in surgeon decision making and a reliance on single centre, retrospective studies with small patient numbers. To address gaps in knowledge regarding screening, diagnosis and management of DDH, the International Hip Dysplasia Institute began a multicentre, international prospective study on infants with hips dislocated at rest...

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...

BACKGROUND: When treatment of acute septic arthritis of the hip is delayed, severe sequelae can occur. This may take the form of coxa breva, vara, or valga. Pseudoarthrosis of the femoral neck is a rare complication with only a few studies to guide treatment. QUESTION/PURPOSES: In a small series of patients with pseudarthrosis of the femoral neck after acute septic arthritis, we wanted to determine (1) whether femoral neck union can be achieved using a variety of surgical approaches; (2) whether these patients satisfied criteria outlined by Hunka and Choi, defined as a stable hip, a flexion arc ≥ 70° and no fixed adduction or abduction contractures, fixed flexion deformity not more than 20°, pain relief, and restoration of activities of daily living after surgery; and (3) any treatment-related complications if observed...

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...

BACKGROUND: Pelvic radiotherapy is a treatment delivered to an estimated 150,000 to 300,000 people annually across high-income countries. Fractures due to normal stresses on weakened bone due to radiotherapy are termed insufficiency fractures. Pelvic radiotherapy-related interruption of the blood supply to the hip is termed avascular necrosis and is another recognised complication. The reported incidences of insufficiency fractures are 2.7% to 89% and risk of developing avascular necrosis is 0...
