Femoral Anteversion and the Neck-shaft Angle: Relationship with Hip Osteoarthritis
نویسندگان
چکیده
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. RESULTS It was observed that there was no significant variation in femoral anteversion between the diseased and healthy hips. There was strongest agreement between observers 1 and 2 in relation to both the diseased hips (cases) and the healthy hips (controls). Moreover, no significant agreement was found between observers 1 and 3 (p = 0.13) and between observers 2 and 3 (p = 0.12), in relation to the neck-shaft angle of the control hips. CONCLUSION Although there was no relationship between femoral anteversion and the neck-shaft angle in the patients with unilateral hip osteoarthritis, the present study showed that there was also no relationship with these angular deviations.

Background and Objective: Arthrosis of the hip joint is one of the most common complications of patients and many efforts have been made to find its etiology. One of the subjects important for researchers is morphologic parameters of the hip joint and its relationship with osteoarthritis of this joint. Since these parameters themselves are affected by physical parameters of the body and the rac...
متن کاملInvestigation of association between hip morphology and prevalence of osteoarthritis
The cause of hip osteoarthritis (OA) remains unclear, morphologic abnormality of hip was thought to be a contributing factor to hip OA. The hypothesis was that there were subtle anatomical morphology differences of the hip between normal and OA subjects; the objective of this study was to explore these anatomical differences which are predisposing to hip OA based on CT 3D reconstruction. Ninety...
متن کاملAcetabular and proximal femoral alignment in patients with osteoarthritis of the dysplastic hip and its influence on the progression of disease.
In order to evaluate the relationship between acetabular and proximal femoral alignment in the initiation and evolution of osteoarthritis of the dysplastic hip, the acetabular and femoral angles were calculated geometrically from radiographs of 62 patients with pre-arthrosis and early osteoarthritis. The sum of the lateral opening angle of the acetabulum and the neck-shaft angle was defined as ...

Background and purpose: Ôsteoarthrisis is the most common disease of mobile and axial joints, its etiology is not clearly known yet. Biomechanical and biological theories are suggested for its etiology. The relationship between proximal femoral anatomy and osteoarthrisis of the hip is under controversy. Materials and methods : 73 individuals, 34 with osteoarthrisis and 39 control cases wer...
متن کاملThree-dimensional anatomy of the hip in osteoarthritis after developmental dysplasia.
Using radiography and computer tomography (CT) we studied the morphology of 83 hips in 69 Caucasian adults with osteoarthritis secondary to developmental dysplasia of the hip (DDH). A previously published series of 310 hips with primary osteoarthritis was used as a control group. According to the Crowe classification, 33 of the dysplastic hips were graded as class I, 27 as class II and 23 as cl...
