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.

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.

Spontaneous femoral neck fracture resulting from osteonecrosis involving lateral femoral head-neck junction: a retrospective study

BMC Musculoskeletal Disorders, 2023
Background Spontaneous femoral neck fracture is a rare condition that remains controversial due to limited reported cases. This retrospective study aims to provide further insights into the etiology and characteristics of the disease. Method We conducted

Proper mechanical stress promotes femoral head recovery from steroid-induced osteonecrosis in rats through the OPG/RANK/RANKL system

BMC Musculoskeletal Disorders, 2020
Background Long-term use of steroid may lead to osteonecrosis of the femoral head (ONFH). Mechanical stress may help bone formation and remodeling. This study aimed to probe the role of mechanical stress in the femoral head recovery in rats.

Osteonecrosis of the Femoral Head: Update Article.

Revista brasileira de ortopedia, 2022
Among the pathologies that affect the hip joint, osteonecrosis of the femoral head (ONFH) is probably the most intriguing and challenging. It consists of a multifactorial disease with a highly-variable spectrum in its clinical presentation. It has a devastating effect, due to disabling painful conditions, both for usual activities and sports. Given the

Femoral Osteotomies for Osteonecrosis of the Femoral Head

Biologic Orthopedics Journal, 2021
Transtrochanteric rotational osteotomy (TRO) and transtrochanteric curved varus osteotomy (TCVO) are considered as representative joint-preserving procedures for osteonecrosis of the femoral head. Compared with TRO, TCVO has shorter operation time, less bleeding, lower incidence of osteophyte formation, and lower rate of femoral head collapse. Surgical

Atraumatic osteonecrosis of the humeral head: pathophysiology and current concepts of evaluation and treatment

JSES Reviews, Reports, and Techniques, 2022
The humeral head is considered the second most common site for osteonecrosis to occur after the femoral head. As seen in the femoral head, the circulatory implications characteristic of this condition are attributable to the interaction between a genetic

Prescribing of medication to prevent glucocorticoid harms in patients with Polymyalgia Rheumatica: a cross‐sectional study and two emulated target trials in the Clinical Practice Research Datalink Aurum

Arthritis &Rheumatology, Accepted Article.
Objectives Polymyalgia rheumatica (PMR) is a common indication for long‐term glucocorticoid (GC) treatment. Bone‐ and gastro‐protective medications are recommended for those at high‐risk of adverse events from GCs but no trials have evaluated their effectiveness in PMR.

Femoral neck fracture after femoral head necrosis: a case report and review of the literature

BMC Musculoskeletal Disorders, 2023
Introduction Pathological fractures of the femoral neck caused by necrosis of the femoral head are extremely rare. Here, we report a rare case of bilateral femoral head osteonecrosis extending to the femoral neck, with bilateral pathological fractures of
