Increasing the angle between caudal screw and the transverse plane may aggravate the risk of femoral head necrosis by deteriorating the fixation stability in patients with femoral neck fracture

European Journal of Medical Research
Necrosis of the femoral head is the main complication in femoral neck fracture patients with triangle cannulated screw fixation. Instant postoperative fixation instability is a main reason for the higher risk of femoral head necrosis.

Three-dimensional distribution of subchondral fracture lines in osteonecrosis of the femoral head

Journal of Orthopaedic Translation
Objective: To investigate the characteristics of three-dimensional distribution of subchondral fracture lines on the surface of the osteonecrosis femoral head, and to discuss the underlying mechanisms that contribute to its collapse.

A Rabbit Model of Avascular Necrosis of Femoral Head Using Surgical Trauma and Systemic Steroids

Bezmiâlem Science, 2020
Objective:Avascular necrosis of the femoral head (ANFH) is a disease caused by the diminished circulation of the femoral head. The incidence of the disease is increasing and it has heavy socioeconomical burden.

The influence of femoral head size following total hip replacement and hip resurfacing on hip biomechanics during walking, stair use and sit-to-stand [PDF]

Due to geometrical features, it is claimed that larger femoral heads in total hip replacement (THR) are superior in achieving normal biomechanics than smaller ones; and that hip resurfacing (RSF) is superior to THR. This has not been conclusively proven.

The use of 3D surface analysis techniques to investigate the wear of matt surface finish femoral stems in total hip replacement [PDF]

, 2006
Total hip replacement is one of the most common surgical procedures carried out both in the UK and Worldwide. With an increasing number of younger patients undergoing the procedure, there is an emphasis on increasing the longevity of prostheses.

Axial STIR MRI: A faster method for confirming femoral head reduction in DDH

Journal of Children's Orthopaedics, 2009
Purpose Non-concentric reduction of the femoral head within the acetabulum is detrimental to its delicate cartilaginous structure and may result in a growth disturbance.

A Rare Form of Microcephalic Primordial Dwarfism due to NSMCE2 Deficiency (Seckel Syndrome Type 10): A Report of Macular Involvement

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic variants in NSMCE2 (MMS21), which encodes the SUMO E3 ligase subunit of the SMC5/6 chromatin‐maintenance complex, have recently been implicated in microcephalic primordial dwarfism (MPD), corresponding to Seckel syndrome type 10 (OMIM #617246).

The ratio between the screw distance and femoral neck width on lateral radiography is a reliable predictor of femoral head necrosis: a clinical review and corresponding numerical simulations

Journal of Orthopaedic Surgery and Research
Background Fixation instability serves as an initial trigger for femoral head necrosis in patients with femoral neck fractures undergoing internal fixation. The configuration of screw trajectories is critical in determining the stability of the fixation.

Osteonecrosis of the Femoral Head Caused by Bone Marrow Blockage: A Case Report

Journal of Orthopaedic Surgery, 2006
Interruption of the blood flow may occur in intraosseous arteries within the femoral head. We report a 72-year-old woman who developed osteonecrosis of the femoral head 11 months after surgery involving massive cementing of a segmental distal femoral ...

Femoroacetabular Impingement (FAI) Syndrome : the medical imaging perspective [PDF]

, 2014
Introduction: Sports persons, physicians, orthopods and radiologists have become increasingly aware of the extra stress that is imposed on the hip joints with excessive activity particularly when superadded weight bearing and asymmetrical variations from
