Osteonecrosis of the femoral head is a disorder that leads to collapse and osteoarthritis in young patients. This study examines the effectiveness of pulsed electromagnetic fields [PEMF] in the treatment of osteonecrosis of the head in precollapse bone stages. A retrospective evaluation was done of 51 patients including 70 hips with symptomatic osteonecrosis of the hip treated with pulsed elect...

BACKGROUND Anterior cruciate ligament (ACL) reconstruction is performed commonly, with a low risk of complication. Osteonecrosis of the knee is a potentially devastating condition and has been observed both spontaneously and after meniscectomy, although osteonecrosis has not been described as a complication after ACL reconstruction. PURPOSE To describe the development of osteonecrosis of the ...

Aim. This article covers the authors‘ experience with the treatment of bisphosphonate-related osteonecrosis of the jaw in 11 individuals. Methods. A retrospective study of patients diagnosed and treated for bisphosphonate-related osteonecrosis of the jaw at the Department of Dentistry, University Hospital Hradec Králové during the period January 2006 to October 2012.

BACKGROUND Bisphosphonate Osteonecrosis of the Jaw (BRONJ) is a newly recognized condition reported in patients treated with aminobisphosphonates (BF). BRONJ is defined as the presence of exposed necrotic alveolar bone that does not resolve over a period of 8 weeks in a patient taking bisphosphonates who has not had radiotherapy to the jaw. Treatment protocols have been outlined, but trials and...

Corticosteroid can induce osteonecrosis in children with leukemia. Few studies have been designed to assess the influence of a wide range of cumulative steroid dose on this side effect. Prevalence, risk factors of symptomatic osteonecrosis and its impact on adults' Quality of Life were assessed in 943 patients enrolled in the French "Leucémies de l'Enfant et de l'Adolescent" (LEA) cohort of chi...

Osteonecrosis of the femoral head during pregnancy, or shortly thereafter, is a rare clinical problem. Little is known about pregnancy as an etiological factor for femoral head osteonecrosis with only 40 reported cases in the literature. Furthermore, single or dual dose steroid-induced multifocal osteonecrosis is a controversial topic with only a handful of published cases. We present a case of...

Idiopathic osteonecrosis of the hip in twins The pathogenesis of osteonecrosis is not completely understood.' 3 Circulatory impairment leading to bone necrosis is one of the principal features. Many clinical disorders have been associated with osteonecrosis but in most cases a specific pathogenic mechanism remains unclear. Several mechanisms may explain the interruption of the blood supply such...

Glucocorticoids are important therapy for acute lymphoblastic leukemia (ALL) and their major adverse effect is osteonecrosis. Our goal was to identify genetic and nongenetic risk factors for osteonecrosis. We performed a genome-wide association study of single nucleotide polymorphisms (SNPs) in a discovery cohort comprising 2285 children with ALL, treated on the Children's Oncology Group AALL02...

The incidence and clinical and magnetic resonance imaging features of osteonecrosis of the hip were evaluated in patients with aplastic anemia. Two hundred and forty-one patients with aplastic anemia were examined using MR imaging of bone marrow during the five years from 1994 to 1998. Osteonecrosis of the hip was observed on MR imaging in nineteen (15 males and 4 females, mean age 35 yr) of th...
