BACKGROUND Favourable clinical outcomes achieved with liver transplantation may be jeopardised by corticosteroid-induced osteoarticular complications, such as osteoporosis or aseptic osteonecrosis. CASE REPORT A previously unreported joint complication in liver transplant recipients is described. METHODS Retrospective study of liver transplant recipients in whom destructive joint disease de...

About 1 in 3 people suffer from bone and joint disease, which is a disease of bone and cartilage cells. Osteonecrosis of the femoral head (ONFH) is a typical example of bone and joint disease involving bone cell necrosis. Osteonecrosis of the femoral head leads to the occurrence of premature osteoarthritis of the hip and collapse of the cartilage cells, and there is currently no effective drug ...

Osteonecrosis or avascular necrosis (AVN) of the hip is a progressive disease mainly affecting adults in their third, fourth or fifth decade of life. Studies into the natural history of the disease suggest that femoral head collapse occurs within 2-3 yrs with associated degenerative changes and at that stage arthroplasty is the most reliable treatment option. Therefore prevention of femoral hea...

Purpose. The purpose of our study is to evaluate the therapeutic efficacy of short-segment percutaneous pedicle screw fixation with polymethylmethacrylate (PMMA) augmentation for the treatment of osteoporotic thoracolumbar compression fracture with osteonecrosis. Methods. Osteoporotic thoracolumbar compression fractures with avascular necrosis were treated by short-segment PPF with PMMA augment...

Avascular osteonecrosis of the femoral head (AONFH) usually goes through the four stages described by Arlet and Ficat: normal radiographs, heterogeneity and sclerosis of the femoral head, subchondral fracture with an individualized sequestrum, and secondary osteoarthritis. Arlet and Ficat individualized a specific pattern of AONFH which they called ischemic hip disease, in which cartilage damag...

Osteonecrosis is an ischemic process in the juxta-articular bone. Two forms of osteonecrosis are distinguished, one in which infarction occurs in bone marrow, causing no clinical signs, and another involving the cortical medulla, with a more florid clinical picture. Multifocal osteonecrosis is defined as a disease affecting three or more separate anatomical regions. Its preferential locations i...

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...

Osteonecrosis of the femoral head (ONFH), also known as femoral head avascular necrosis, is a pathological state with a number of possible etiologies including steroid administration, alcohol abuse, traumatic events, vascular injury and idiopathic origins. ONFH causes a reduction in the vascular supply to the subchondral bone of the femoral head, which results in osteocyte death and the collaps...

OBJECTIVES Talar neck and body fractures are unusual fractures. The purpose of this study is to determine the prevalence of long term results. MATERIAL AND METHODS A retrospective analysis was carried out including 11 patients that underwent surgical treatment for body or neck talus fractures between January 1997 and December 2005. Final follow-up examination included a clinical evaluation (A...
