Femoral Anteversion and the Neck-shaft Angle: Relationship with Hip Osteoarthritis
OBJECTIVE To compare the existence of agreement between measurements of anteversion of the femoral neck and the degrees of osteoarthritis and abnormality of the neck-shaft angle in patients with unilateral idiopathic hip osteoarthritis, among three evaluators. METHODS Forty-two patients with unilateral hip osteoarthritis were evaluated by means of simple radiography and computed tomography. ...
متن کاملFemoral Version, Neck-Shaft Angle, and Acetabular Anteversion in Chinese Han Population
Anatomic data regarding femoral version, neck-shaft angle, and acetabular anteversion are still limited in Chinese Han adult population. The aim of this study was to investigate the effects of age, sex, and body laterality on the 3 important anatomic indicators in Chinese Han healthy adults. Measurements were performed independently by 3 experienced observers using the picture archiving and com...
متن کاملMeasurement of Collo-diaphyseal Angle and Femoral Neck Anteversion Angle of Femur Bone
Introduction: The femur is the weight-bearing typical long bone of lower limb which extends from the pelvis to the knee. Anthropometry provides scientific method and technique for taking various measurements in different geographic regions and races. Aim: The purpose of the study was to measure the average collo-diaphyseal angle (CDA) and femoral neck anteversion (FNA) of dry fully ossified fem...
متن کاملFemoral Neck Shaft Angle in Men with Fragility Fractures
Introduction. Femoral neck shaft angle (NSA) has been reported to be an independent predictor of hip fracture risk in men. We aimed to assess the role of NSA in UK men. Methods. The NSA was measured manually from the DXA scan printout in men with hip (62, 31 femoral neck and 31 trochanteric), symptomatic vertebral (91), and distal forearm (67) fractures and 389 age-matched control subjects. Age...
متن کاملThe Modified Femoral Neck-Shaft Angle: Age- and Sex-Dependent Reference Values and Reliability Analysis
Background. The femoral neck-shaft angle (NSA) is of high importance for the diagnostics and treatment of various conditions of the hip. However, rotational effects limit its precision and applicability using plain radiographs. This study introduces a novel method to measure the femoral NSA: the modified NSA (mNSA), possibly being less susceptible against rotational effects compared to the conv...
