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

Curved Intertrochanteric Varus Osteotomy vs Total Hip Arthroplasty for Osteonecrosis of the Femoral Head in Patients Under 50 Years Old [PDF]

, 2020
Background: Given recent advances in total hip arthroplasty (THA), curved intertrochanteric varus osteotomy (CVO) is not indicated as a treatment for osteonecrosis of the femoral head (ONFH), unless indicated to maintain long-term hip function and ...

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.

Scintigraphic assessment of bone status at one year following hip resurfacing : comparison of two surgical approaches using SPECT-CT scan [PDF]

, 2012
Objectives: To study the vascularity and bone metabolism of the femoral head/neck following hip resurfacing arthroplasty, and to use these results to compare the posterior and the trochanteric-flip approaches.

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.

A Rabbit Model of Avascular Necrosis of Femoral Head Using Surgical Trauma and Systemic Steroids

Bezmiâlem Science, 2020
Objective:Avascular necrosis of the femoral head (ANFH) is a disease caused by the diminished circulation of the femoral head. The incidence of the disease is increasing and it has heavy socioeconomical burden.

AAV-Anti-miR-214 Prevents Collapse of the Femoral Head in Osteonecrosis by Regulating Osteoblast and Osteoclast Activities

Molecular Therapy: Nucleic Acids, 2019
Osteonecrosis of the femoral head, an intractable but common disease that eventually triggers collapse of the femoral head, is characterized by increased osteoclast activity and markedly decreased osteoblast activity in the necrotic region of the femoral

Accuracy of MRI diagnosis of early osteonecrosis of the femoral head: a meta-analysis and systematic review

Journal of Orthopaedic Surgery and Research, 2018
Objective To evaluate the overall diagnostic value related to magnetic resonance imaging (MRI) in patients with early osteonecrosis of the femoral head. Methods By searching multiple databases and sources, including PubMed, Cochrane, and Embase database,

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.

Factors associated with dislocation after total hip arthroplasties performed for nontraumatic osteonecrosis of the femoral head: a multicenter cohort study of 5,983 hips

Acta Orthopaedica
Background and purpose: Nontraumatic osteonecrosis of the femoral head (ONFH) patients are at a higher dislocation risk after primary total hip arthroplasties (THAs) than osteoarthrosis patients.
