BACKGROUND Avascular necrosis after arthroscopic surgery of the knee has already been published. The purpose of this article is to report on the frequently misdiagnosed entity of osteonecrosis of the medial tibial plateau. CASE PRESENTATION Charts and radiographs of a consecutive series with isolated medial tibial plateau osteonecrosis were analyzed. The criterion for inclusion was the absenc...

Introduction: Avascular necrosis (AVN) of the femoral head is a leading cause of end-stage joint disease in the young population that can conduct patients to total hip replacement in early life. There are various risk factors including, trauma, corticosteroids, thrombosis, hypertension, and alcohol. There is a growing number of femoral head AVN patients with a history of self-medication with he...

Cancer patients have a better prognosis now than in the past. An estimated 66% of patients diagnosed with cancer between 1996 and 2004 were alive at 5 years.1 As patients are living longer after treatment, long-term complications associated with treatment are becoming a greater issue. Avascular necrosis, also referred to as osteonecrosis, ischemic necrosis, subchondral avascular necrosis, asept...

To explore the correlation analysis between level of coagulation function and osteonecrosis femoral head is main objective study. Osteonecrosis end point disease process due to inadequate blood flow bone tissue, later in disease, collapse, arthritis or even hip replacement surgery may be required. Therefore, it called avascular necrosis a common intractable orthopedics clinic. According statist...

Avascular necrosis of the femoral head is caused by a multitude of etiologic factors and is associated with collapse with a risk of hip arthroplasty in younger populations. A focus on early disease management with the use of stem cells was proposed as early as 1985 by the senior author (PH). We undertook a systematic review of the medical literature to examine the progress in cell therapy durin...

ABSTRACT A 47-year-old gentleman, with underlying seborrhoeic dermatitis that was treated with steroid therapy, and hepatitis B, presented with pain in his right hip. He was diagnosed with stage 2 osteonecrosis of the right hip (Ficat and Arlet classification). Core decompression and bone grafting was performed but recovery was complicated by a surgical site infection. Wound debridement, remova...

Three men (aged 33, 44 and 45 years, CD4(+) T-cell nadir 86 cells/mm(3), 99 cells/mm(3) and 12 cells/mm(3), respectively) were admitted to the Department of Infectious Diseases (Treichville Hospital, Abidjan, Côte d'Ivoire) for hip pain and impaired mobility. Their last available CD4(+) T-cell counts were 243 cells/mm(3), 245 cells/mm(3) and 8 cells/mm(3), respectively. They had all received an...

UNLABELLED Avascular necrosis of the first metatarsal head is a well-known, albeit rare, complication associated with hallux abductovalgus surgery. In this report, we describe the case of a 51-year-old male who developed osteonecrosis of the first metatarsal head 1 year after undergoing an isolated cheilectomy for the treatment of hallux rigidus. To our knowledge, this is the first published re...

BACKGROUND Avascular necrosis of bone (osteonecrosis) can cause structural failure and subsequent deformation, leading to joint dysfunction and pain. Structural failure is the result of resorption of necrotic bone during revascularization, before new bone has formed or consolidated enough for loadbearing. Bone resorption can be reduced by bisphosphonates. If resorption of the necrotic bone coul...
