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.

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.

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

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

Chinese Expert Consensus on the Clinical Application of Finerenone in Geriatric Comorbidities

AGING MEDICINE, EarlyView.
Mineralocorticoid receptor (MR) overactivation drives inflammation, oxidative stress, and fibrosis in the heart, kidneys, and vasculature, leading to cardiorenal dysfunction. MR signaling promotes hypertrophy, remodeling, and injury through pathways like oxidative stress and inflammation, resulting in vascular stiffness and progressive organ damage ...

Hip Arthroscopy in Adults Aged 40 or Older Produces Clinically Meaningful Symptom Improvement but Carries a Substantial Risk of Conversion to Total Hip Arthroplasty: A Systematic Review

Arthroscopy, EarlyView.
Purpose To report conversion rates to total hip arthroplasty (THA), patient‐reported outcome measures, and complication rates in adults aged ≥ 40 years undergoing hip arthroscopy since 2016. Methods MEDLINE, EMBASE, and PubMed were searched from January 2016 to March 2025, and pertinent data were abstracted from eligible studies according to the ...

Performance of the resurfaced hip. Part 1: the influence of the prosthesis size and positioning on the remodelling and fracture of the femoral neck

, 2010
Hip resurfacing is an established treatment for osteoarthritis in young active patients. Failure modes include femoral neck fracture and prosthesis loosening, which may be associated with medium-term bone adaptation, including femoral neck narrowing and ...

ANK1 and EPB41 Variants and The Risk of Glucocorticoid‐Induced Osteonecrosis

Arthritis &Rheumatology, EarlyView.
Objective Steroid‐induced osteonecrosis of the femoral head (SONFH) is a refractory skeletal disorder influenced by genetic and environmental factors. However, conclusive pathogenic genetic evidence remains elusive due to the limited exploration of rare damaging variants. In this study, we aimed to identify rare variants associated with SONFH.

Low expression of vascular endothelial growth factor and high serum level of cyclic guanine monophosphate as the risk factors of femoral head osteonecrosis in alcohol-exposed Wistar rat

Chinese Journal of Traumatology, 2020
Purpose: Severe damage to the femoral head in patients with osteonecrosis has a high impact on morbidity. Despite early diagnosis, the treatment outcome is still unsatisfactory.
