Sclerotic zone in femoral head necrosis: from pathophysiology to therapeutic implications
EFORT Open Reviews, 2023 This review summarizes the sclerotic zone's pathophysiology, characterization, formation process, and impact on femoral head necrosis. The sclerotic zone is a reaction interface formed during the repair of femoral head necrosis.

Current Reviews in Musculoskeletal Medicine, 2012 Femoral head fractures may present in various patterns with or without associated fractures around the hip. As a result, the treating orthopaedic surgeon must understand not only the fracture pattern, but also patient-related fractures and the relevant operative exposures and reconstructive options to achieve the best functional outcome while ...

Osteonecrosis of the Femoral Head
JAAOS: Global Research and Reviews, 2022 Osteonecrosis of the femoral head is a progressive and debilitating condition with a wide variety of etiologies including trauma, steroid use, and alcohol intake. Diagnosis and staging are based on imaging including MRI at any stage and plain radiography in more advanced lesions.

Effect of geometrical, operational and material parameters in the lubrication regime of hard-on-hard hip implants [PDF]
Materials Chemistry and Physics 317 (2024) 129171, 2023 Several factors, such as the material, geometry, roughness, relative angular movement and loading conditions, influence the hip implant's lubrication regime, thereby affecting the friction and wear performance including longevity. In this study, a ball-on-plane model is considered to predict the lubrication regime across the entire gait cycle for the ...

Nontraumatic Osteonecrosis of the Femoral Head: Where Do We Stand Today?: A 5-Year Update.
Journal of Bone and Joint Surgery. American volume, 2020 Clinicians should exercise a high level of suspicion in at-risk patients (those who use corticosteroids, consume excessive alcohol, have sickle cell disease, etc.) in order to diagnose osteonecrosis of the femoral head in its earliest stage.

Femoral Neck Angle Impacts Hip Disorder and Surgical Intervention: A Patient-Specific 3D Printed Analysis [PDF]
ACM International Conference Proceeding Series 2019, 2020 The purpose of this study is to investigate the femoral neck angulation for prediction of the complication associated with dynamic hip screw (DHS) surgery and hip deformity. Three sample patients' MRI images were selected to calculate the femoral neck angles.

Effect of Femoral Head Necrosis Cystic Area on Femoral Head Collapse and Stress Distribution in Femoral Head [PDF]
, 2021 Abstract Objective:Osteonecrosis of the femoral head (ONFH) is a common and difficult disease. The effect of cystic area on femoral head mechanics in patients with ONFH is unknown. The purpose of this study was to investigate the effect of cystic areas of osteonecrosis of the femoral head on stress distribution and disease progression in the ...
