Morphological and Mechanical Evaluation of the Cancellous Bone in the Rat Femoral Head after Traumatic Osteonecrosis

Journal of Biomechanical Science and Engineering, 2006
Over 7000 patients are suffering from osteonecrosis of the femoral head annually in Japan. The patients have to undergo surgical treatments if the femoral head collapsed. The mechanism of femoral head collapse is still unclear, although morphological and

Cell-based Treatments of Femoral Head Osteonecrosis: A Literature Review [PDF]

Reviews in Clinical Medicine, 2018
The preferred desire of orthopedic surgeons is to preserve the femoral head in the early stages of femoral head osteonecrosis; however, hip arthroplasty is needed in most cases.

Knee loading protects against osteonecrosis of the femoral head by enhancing vessel remodeling and bone healing [PDF]

, 2015
Osteonecrosis of the femoral head is a serious orthopedic problem. Moderate loads with knee loading promote bone formation, but their effects on osteonecrosis have not been investigated.

Etiology of avascular osteonecrosis of the femoral head

Morphologie, 2021
Avascular osteonecrosis of the femoral head (ONFH) is one of the causes of hip pain that clinicians need to know about. In many cases, it is a fortuitous discovery when pelvic X-rays is performed for another reason. In the other cases, pain reveals the disease. For the rheumatologist, a major part of the job is to look for a cause.

The effect of core decompression on local expression of BMP-2, PPAR-γ and bone regeneration in the steroid-induced femoral head osteonecrosis

BMC Musculoskeletal Disorders, 2012
Background To investigate the efficacy of the sole core decompression surgery for the treatment of steroid-induced femoral head osteonecrosis. Methods The model was established by administration of steroids in combination with horse serum.

Legg-Calvé-Perthes disease and the risk of injuries requiring hospitalization [PDF]

, 2012
Background and purpose Previous studies have suggested that Legg-Calvé-Perthes disease (LCPD) is associated with repetitive trauma, coagulation problems and anatomical abnormalities of the blood supply to the femoral head. The hypothesis that repetitive

Application of OCT for osteonecrosis using an endoscopic probe based on an electrothermal MEMS scanning mirror

International Journal of Optomechatronics, 2021
Osteonecrosis becomes a more widespread problem as the population is getting older. Current osteonecrosis diagnosis not only requires invasive procedures but also often leads to surgical replacement.

Efficacy of autologous bone marrow buffy coat grafting combined with core decompression in patients with avascular necrosis of femoral head: a prospective, double-blinded, randomized, controlled study [PDF]

, 2014
Introduction Avascular necrosis of femoral head (ANFH) is a progressive disease that often leads to hip joint dysfunction and even disability in young patients.

Apoptosis in the Osteonecrosis of the Femoral Head

Clinics in Orthopedic Surgery, 2010
Osteonecrosis of the femoral head is classified into idiopathic and secondary forms. A number of etiological factors in the development of osteonecrosis have been suggested but the biological mechanisms are still unclear. Recently, some reports suggested that the apoptosis is closely related to osteonecrosis of the femoral head.
