With disease progression, avascular necrosis (AVN) of the femoral head may lead to a collapse of the articular surface. The exact pathophysiology of AVN remains unclear, although several conditions are known that can result in spontaneous cell death, leading to a reduction of trabecular bone and the development of AVN. Hip AVN treatment is stage-dependent in which two main stages of the disease can be distinguished: pre-collapse (ARCO 0-II) and post-collapse stage (ARCO III-IV, crescent sign). In the pre-collapse phase, core decompression (CD), with or without the addition of bone marrow (e...

BACKGROUND: Unstable slipped capital femoral epiphysis (SCFE) has a relatively high risk of avascular necrosis of the femoral head. Standard treatment for unstable SCFE is still controversial. We reviewed unstable SCFE case series treated with the standardized protocol, which consisted of percutaneous pinning after prolonged skeletal traction. METHODS: Our treatment regimen for unstable SCFE patients included 1 week or more of skeletal traction with the hip in a flexed position of 45 degrees, and subsequent percutaneous pinning after unintentional reduction...

Arthroscopic surgery for femoroacetabular impingement (FAI) is increasingly frequently performed. Initial reports were that complications were very low, but as experience has increased, a number of long-term complications, in addition to factors related to poor clinical outcomes, have been identified. This review describes the normal and abnormal postoperative imaging appearance of the hip after arthroscopy for FAI. Abnormalities discussed include incomplete resection or over-resection of the impingement lesion, heterotopic ossification, cartilage damage, chondrolysis, instability and dislocation, recurrent labral tear, adhesions, psoas atrophy, infection, and avascular necrosis...

Avascular necrosis (AVN) of the femoral head (FH) causes 5% to 12% of total hip arthroplasties (THA). It especially affects active male adults between the third and fifth decades of life. The exact worldwide incidence is unknown. There are only few data related to each country, but most of it relates to the United States.Non-surgical management has a very limited role in the treatment of AVN of the FH and only in its earliest stages. Core decompression (CD) of the hip is the most common procedure used to treat the early stages of AVN of the FH...

BACKGROUND: Acetabular fractures are quite challenging injuries for the orthopedic surgeon because of their low incidence and their deep and complex anatomy. The objective of this study was to evaluate surgeon-independent parameters that might influence radiographic outcome and early complication rates of high-energy acetabular fractures treated by open reduction and internal fixation via the Kocher-Langenbeck approach, the golden standard for posterior access. METHODS: One hundred sixty-seven consecutive patients (111 males and 56 females) with a mean age of 41...

BACKGROUND: Sickle Cell Disease (SCD) is associated with chronic multisystem complications that significantly influence the quality of life (QOL) of patients early in their life. Although sub-Saharan Africa bears 75% of the global burden of SCD, there is a paucity of data on these complications and their effects on the QOL. We aimed to record these chronic complications, to estimate the QOL, and to identify the corresponding risk factors in patients with SCD receiving care in three hospitals in Cameroon...

Bilateral avascular necrosis (AVN) following postictal bilateral fracture neck of the femur is a rare occurrence. Here, we report a case of bilateral AVN of the femoral head following an asynchronous bilateral postictal fracture neck of the femur. A 16-year-old autistic boy presented with left hip pain following an episode of seizures and radiographs showed Delbet type II fracture neck of the left femur. This was treated by closed reduction and cancellous screw fixation and skeletal traction for 6 weeks. At 3 months, follow-up radiograph showed union of the fracture, but he had developed segmental AVN with collapse of the head...

BACKGROUND AND OBJECTIVES: The efficacy of glucocorticoids (GCs) in treating systemic lupus erythematosus (SLE) is beyond doubt. However, GCs-related adverse effects (AEs) are multiple and serious. Despite the current available evidence suggesting to reduce daily doses of prednisone <7.5 mg/day, or even to withdraw it, in the real-life practice, it is not uncommon to see patients receiving medium doses (up to 30 mg/day prednisone or equivalent) or high doses (≥30 mg/day). METHODS: We systematically reviewed the literature with a priori strategy, to assess the rate of AEs related to medium or high doses of GCs in patients with SLE, analyzing randomized control trials with at least one of the treatment groups including GCs alone at medium or high doses...

BACKGROUND: Total hip arthroplasty is the most widely used procedure to treat avascular necrosis (AVN) of the femoral head. Few studies have compared the outcomes of THA in femoral head AVN and primary hip osteoarthritis. Therefore we performed a case-control study to compare THA for femoral head AVN vs. primary hip osteoarthritis in terms of: (1) prosthesis survival, (2) complication rates, (3) functional outcomes and radiographic outcomes, (4) and to determine whether specific risk factors for THA failure exist in femoral head AVN...

BACKGROUND: The modified Dunn procedure (open subcapital realignment via a surgical dislocation approach) has been shown to be a safe and effective way of treating acute, unstable slipped capital femoral epiphysis (SCFE). There is a paucity of literature comparing the modified Dunn procedure in stable SCFE. The purpose of this study was to compare acute, unstable versus chronic, stable SCFE managed with the modified Dunn procedure. METHODS: A retrospective chart review was performed on 44 skeletally immature patients who underwent the modified Dunn procedure for SCFE...

PURPOSE: Hip fractures in hemodialysis patients are accompanied by high rates of complications and morbidities. Previous studies have mainly reported on nonunion and avascular necrosis of femoral neck fractures in this patient group. In this study the complication and clinical results of hemodialysis patients with intertrochanteric fractures treated with proximal femoral intramedullary nailing have been investigated through comparison with patients with normal kidney function. MATERIALS AND METHODS: Forty-seven patients were included; the hemodialysis group (n=17) and the control group with normal kidney function (n=30)...

Transient osteoporosis of the hip (TOH) is a temporary clinical condition of unknown etiology which usually resolves with conservative therapy though may be complicated by fracture or progression to avascular necrosis (AVN). TOH may be slightly more prevalent in men but when it occurs in women, it is most often seen in the latter part of pregnancy. Though fracture is a rare complication of TOH when it occurs, it is most often associated with TOH occurring in pregnancy. Magnetic resonance imaging (MRI) is the best method to diagnosis TOH...

BACKGROUND: Many children with developmental dislocation of the hip especially in underdeveloped countries reach walking age and still remain undiagnosed, which can be detrimental to their growth and development. Because of the lack medical services often encountered in these regions, it would be attractive to find a cheap and effective treatment. Our work evaluated the results of treatment of these children by closed reduction with or without adductor tenotomy in a prospective study...
