Osteochondritis dissecans (OCD) of the femoral head is not a common source of hip pain. Hip arthroscopy is becoming a more frequent indication for intra-articular pathologies of the hip. Osteochondral autologous transplantation is a promising technique that theoretically can reconstruct osteochondral lesions of the femoral head. We describe our technique for arthroscopic antegrade osteochondral...

Background.Avascular necrosis of the femoral head continues to represent a major challenge for the orthopaedist and trauma surgeon. A fully effective method of treatment is yet to be introduced. After femoral head collapse, only total hip replacement can help the patient. Our study aims to assess the effects of treatment of avascular necrosis of the femoral head with extra corporeal focused sho...

Osteochondral lesions of the femoral head are uncommon and few studies have reported their imaging findings. Since joints are at risk of early degeneration after osteochondral damage, timely recognition is important. Osteochondral lesions of femoral head may often be necessary to differentiate from avascular necrosis. Here, we report a case of osteochondral lesions on bilateral femoral heads. T...

Of 899 patients with sickle-cell disease, aged between 6 and 28 years, who attended clinics in the Guinea Savannah of Nigeria in 1982 and 1983, 29 had symptoms of avascular necrosis of the femoral head. This group was studied in detail. Twenty-eight patients had haemoglobin-SS electrophoretic patterns and one had haemoglobin-SC. The male to female ratio was 1 to 1.6, and most of the patients we...

A 11 year old boy was brought to the accident and emergency department with a painful left hip after having been injured it in a tackle in a casual game of rugby. On examination the hip was found to be flexed, adducted and internally rotated with no distal neurovascular deficit. All movements of that hip were extremely painful. Posterior dislocation of hip was confirmed by radiograph (fig 1).Th...

We describe a rare association of Cushing's disease causing avascular osteonecrosis of the femoral head in a patient with operated pituitary macroadenoma. Avascular necrosis of the femoral head (AVN) is not a common cause of musculoskeletal disability. Though AVN of the hip is a well-recognized complication of steroid treatment, it is rare in cases of endogenous hypercortisolism. To our knowled...

INTRODUCTION Avascular necrosis of the head of femur (AVNF) has frequently been reported with sickle cell anemia but is not commonly associated with beta thalassemia. CASE REPORT We report a case of 14-year-old male with transfusion-dependent thalassemia (TDT) and hepatitis C, who developed bilateral atraumatic AVNF requiring surgical correction. The likely etiopathogenesis and the review of ...

This paper presents a supervised texton based approach for the accurate segmentation and measurement of ultrasound fetal head (BPD, OFD, HC) and femur (FL). The method consists of several steps. First, a non-linear diffusion technique is utilized to reduce the speckle noise. Then, based on the assumption that cross sectional intensity profiles of skull and femur can be approximated by Gaussian-...

BACKGROUND Conventional technique of valgus osteotomy of the proximal femur involves removal of a partial or full thickness lateral based wedge from the peritrochanteric region. The purpose of this article is to describe a novel technique of valgus subtrochanteric osteotomy for proximal femur nonunion. METHODS 11 patients with proximal femur nonunions {intracapsular fractures--7, extracapsula...

We quantified differences in trabecular volumetric bone mineral density (BMD) of the femoral head between patients with proximal femoral fractures and healthy subjects in the control group by using quantitative computed tomography (QCT) with the purpose of providing guidance for the choice of head screw in the intramedullary nail fixation. Participants suffering from intertrochanteric fractures...
