THE EVALUATION OF HIP JOINT SPACE IN CLINICALLY NORMAL HIPS AS AN INDICATOR OF EARLY OSTEOARTHRITIS
Abstract:
Osteoarthritis is a main reason of pain in elderly, the joint space width being the most used
criteria in the assessment of the hip joint articular cartilage thickness. The aim of our study was to
measure a set of parameters on clinically asymptomatic patients with normal radiographic aspect of
hips and to compare the results with the joint space width. The recorded parameters were: gender,
age, center-edge angle of Wiberg, neck-shaft angle and acetabular depth. The Wiberg angle was
inversely associated with the joint space width and the mean acetabular depth was 12.5 mm, positively
associated with the superomedial joint space width. A head-neck ratio of 1.35 and neck-shaft angle
were not correlated with the joint space width values. The Wiberg angle can be considered a
radiological parameter inversely related to the joint space width of the hip joints. We found no
association between aging and hip joint space narrowing.
