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.

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,

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.

Complications of Uncemented Total Hip Arthroplasty: Failure

, 2017
We present the case of a total hip arthroplasty (THA) complicated by deep infection performed in a patient diagnosed with osteonecrosis of the femoral head. In general, contemporary total hip arthroplasty provides excellent results. However, the outcomes

Performance of the resurfaced hip. Part 2: the influence of prosthesis stem design on remodelling and fracture of the femoral neck [PDF]

, 2010
Hip resurfacing is a popular treatment for osteoarthritis in young, active patients. Previous studies have shown that occasional failures – femoral neck fracture and implant loosening, possibly associated with bone adaptation – are affected by prosthesis

Vascularity of femoral head and its assessment after femoral neck fractures

Journal of Orthopaedic Diseases and Traumatology, 2018
Femoral neck fracture has an annual incidence of 1 per 1000 population; in young patients, functional prognosis is not good due to risk of osteonecrosis. Femoral head vascularity is mostly contributed by retinacular vessels and lateral epiphyseal artery.

Osteonecrosis of the Femoral Head with Collapsed Medial Lesion

, 2014
A 60-year-old female experienced the gradual onset of left hip pain without any triggering event. Radiographs showed vertical sclerosis in the center of the femoral head and the lesion inside the boundary demonstrated diffuse bony sclerosis.
