A combined radiomics-clinical nomogram for assessing MRI-defined femoral Head collapse status in osteonecrosis of the femoral Head. [PDF]

J Appl Clin Med Phys
Abstract Background Osteonecrosis of the femoral head (ONFH) frequently progresses to femoral head collapse, resulting in irreversible joint dysfunction and the need for total hip arthroplasty. Reliable assessment of magnetic resonance imaging (MRI)‐defined collapse status remains limited with conventional assessment methods.

Impact of Preoperative Non-Collapse and Collapse Durations on Total Hip Arthroplasty Outcomes in Nontraumatic Osteonecrosis of the Femoral Head. [PDF]

Orthop Surg
While total hip arthroplasty provides an equalized functional recovery regardless of preoperative disease duration, surgical timing significantly impacts postoperative pain. Specifically, operating during the 1–3‐year post‐collapse window is an independent risk factor for inferior pain relief, highlighting the critical impact of temporal factors on ...

Predicting the collapse of the femoral head due to osteonecrosis: From basic methods to application prospects

Journal of Orthopaedic Translation, 2017
Collapse of the femoral head is the most significant pathogenic complication arising from osteonecrosis of the femoral head. It is related to the disruption of the maintenance of cartilage and bone, and results in an impaired function of the vascular ...

AVASCULAR NECROSIS OF THE FEMORAL HEAD AFTER COVID-19: A CASE REPORT

Anti-Aging Eastern Europe, 2023
Avascular necrosis of the femoral head can traumatic or non-traumatic in origin. Embolism (hemoglobinopathies, dysbaric osteonecrosis), corticosteroid treatment, alcohol usage, pelvic irradiation, and genetic susceptibility are among the causes of this ...
