Treatment of osteonecrosis of the femoral head using autologous cultured osteoblasts: a case report

Journal of Medical Case Reports, 2008
Introduction Osteonecrosis of the femoral head is a progressive disease that leads to femoral head collapse and osteoarthritis. Our goal in treating osteonecrosis is to preserve, not to replace, 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.

Fracture-dislocations of the femoral head

Orthopaedics & Traumatology: Surgery & Research, 2013
This review describes bone and nerve injury mechanisms during a femoral head fracture-dislocation and outlines a novel classification system that uses computed tomography scanning (CT scan) to help determine how to best treat these fractures in an emergency setting or in chronic cases.

The Impact of Varying Femoral Head Length on Hip External Rotation During Posterior-approach Total Hip Arthroplasty

Arthroplasty Today, 2023
Background: Prior investigations of total hip arthroplasty (THA) have studied the effects of prosthetic femoral head size and stem offset on hip range of motion (ROM), impingement risk, and overall hip stability to optimize the return to activities of ...

Efficacy of artificial femoral head replacement for femoral head avascular necrosis

Medicine, 2019
Abstract Background: Femoral head avascular necrosis (FHAN) is one of the most common progressive orthopedic disorders. Previous studies have reported that artificial femoral head replacement (AFHR) can effectively treat patients with FHAN. However, no systematic review has investigated the efficacy of AFHR for FHAN. This study

A novel model of traumatic femoral head necrosis in rats developed by microsurgical technique

BMC Musculoskeletal Disorders, 2022
Background Clinical angiography and vascular microperfusion confirmed that the femoral head retains blood supply after a collum femur fracture. However, no animal model accurately mimics this clinical situation.

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...
