Although treatment of children infected with HIV with protease inhibitors has improved the survival of these patients, various adverse side effects have been reported, including metabolic abnormalities, such as hyperlipidaemia. We describe a case of hip osteonecrosis in an adolescent with AIDS who was being treated with protease inhibitors. There is a possible relation with hyperlipidemia. F.M....

The efficacy of beta-tricalcium phosphate (beta-TCP) loaded with bone morphogenetic protein-2 (BMP-2)-gene-modified bone-marrow mesenchymal stem cells (BMSCs) was evaluated for the repair of experimentally-induced osteonecrosis of the femoral head in goats. Bilateral early-stage osteonecrosis was induced in adult goats three weeks after ligation of the lateral and medial circumflex arteries and...

We present a case of osteonecrosis of femoral head (ONFH) that occurred after stent angiography of femoral artery for the treatment of arteriosclerosis obliterans (ASO) of left inferior limb in a 76-year-old woman. No case of late collapse of femoral head as a complication of endovascular procedure such as stent placement has been previously documented. We considered that ONFH occurred after de...

The authors describe the case of a 51-year-old woman with an osteonecrosis of her right femoral head after treatment of an atypical subtrochanteric fracture caused by pycnodysostosis. She had this fracture after a low-trauma fall. She was of short stature with typical facial features, short stubby hands, and radiological features including open cranial sutures, obtuse mandible, and generalized ...

Case: A 58-year-old male was reviewed for bilateral hip pain 3 years post cardiac transplant, complicated by episodes of acute rejection, steroid induced diabetes, and cytomegalovirus hepatitis. He diagnosed with femoral head osteonecrosis subchondral collapse underwent staged cementless total arthroplasties. re-presented progressive right knee pain. Investigations revealed diaphyseal a rare in...

BACKGROUND AND PURPOSE One of the main concerns regarding resurfacing arthroplasty is the viability of the remaining part of the femoral head, and the postoperative risk of a femoral neck fracture or collapse. In contrast to radiographic methods, positron emission tomography using the radiotracer [18F]-fluoride (Fluoride-PET) enables us to visualize the viability of bone in the remaining part o...

Objective :The objective of this study is preserving the joint by preventing the collapse of femoral head in Osteonecrosis of femoral head (ONFH) Methods :In this study patients with early ONFH are treated with core decompression and augmented with bone marrow aspirate concentrate spread on a collagen scaffold . Results : Core decompression augmented with bone marrow aspirate concentrate seems ...

The article is based on the importance of applying means and methods specific to physical therapy in improvement Perthes disease. condition known as Perthes, Legg-Perthes, or Legg-Calve-Perthes disease an avascular osteonecrosis epiphysis femoral head. It assumed that through a kinetotherapeutic program appropriate patient's particularities, mobility coxofemoral joint will remain within normal ...

Bipolar hemiarthroplasty of the hip joint has been used for the treatment of femoral neck fractures and osteonecrosis of the femoral head.1-2 This prosthesis originally was believed to decrease shear stress on the acetabular cartilage, resulting in decreased migration.3,4 However, osteolysis of the acetabulum and migration of the head have been reported after bipolar hemiarthroplasty.5-7 This a...

Osteonecrosis of the femoral head occurs predominantly in younger patients, and without treatment most of them suffer from collapse of the femoral head and painful arthritis of the hip joint within several years. The ideal goal of early treatment is to delay or arrest the progression of the disease before articular collapse occurs. It has been well documented that without specific treatment app...
