We hypothesized that inherited thrombophilia and hypofibrinolysis were risk factors for osteonecrosis of the femoral head. We compared measures of thrombophilia and hypofibrinolysis in referred new adult patients with idiopathic osteonecrosis (n = 71) or secondary osteonecrosis (n = 62) with the same measures in sex- and race-matched healthy control subjects. Heritable thrombophilic Factor VIII...
Nontraumatic osteonecrosis of the femoral head is still a challenging problem in orthopedic surgery. It is responsible for 10% of the 500,000 hip replacement surgeries in the USA and affects relatively young, active patients in particular. Main reasons for nontraumatic osteonecrosis are glucocorticoid use, alcoholism, thrombophilia, and hypofibrinolysis (Glueck et al., 1997; Orth and Anagnostak...
[Purpose] This study aimed to determine the effectiveness and mechanisms of extracorporeal shock wave therapy in the treatment of femoral head osteonecrosis. [Subjects and Methods] Histomorphometric analysis of necrotic femoral head in rabbits treated with shock waves was performed. Bilateral osteonecrosis of femoral heads was induced with methylprednisolone and lipopolysaccharide in eight rabb...
Osteonecrosis has long been recognized as a complication of systemic steroid use and was initially believed to occur only in patients who received high doses (equivalent to more than 4000 mg of prednisone) for extended periods (3 months or longer). Previous sporadic case reports have described patients in whom osteonecrosis developed following relatively brief courses (7 days) of lowdose, orall...
background: legg-calve´-perthes disease is a juvenile idiopathic osteonecrosis in which the blood supply of femoral head is not sufficient and the bone dies provisionally. the aim of this study is to evaluate outcome of femoral osteotomy in children with lcpd in our university hospital. methods: in a descriptive analytic study, between 2008 and 2013, patients with the diagnosis of legg-calve’...
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...
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 ...
Spontaneous subcapital fracture (SSF) of femoral neck in pre-existent osteonecrosis head (ONFH) is a rare presentation. Only few cases have been reported so far and majority them to unilateral hip involvement. We retrospectively reviewed clinical-radiological data 10 patients (12 hips) with SSF complicating ONFH. All underwent uncemented total arthroplasty. the available publications English la...
Sickle cell trait is a benign haemoglobin disorder which rarely results in disease or complications. A few cases of osteonecrosis have been reported in the literature in parts of the world with advanced health care system. There are various predispositions to developing avascular necrosis in general, while the sickle beta globin gene inheritance is the most efficient factor. Injection drug abus...
