[Radiologic analysis of osseous changes in coxarthrosis].
Morphologic and osteogenetic changes of the hip joint in patients with coxarthrosis were studied. Examination included 224 patients treated and operated on Department of Orthopaedics, Clinic Hospital Osijek. Coxarthrosis was proved in 331 hips, 183 cases (55,29%) referred to a secondary and 148 844,71%) to primary arthrosis. Osteogenetic changes on the head of femur were found in 148 x-rays (44,71%). The upper osteophyte of the head of femur was found in 79 x-rays of the hip (22,36%) but lower osteophyte of the head of femur only in 26 cases (7,85%). In 48 x-rays (14,50%) osteophytes were found both on the upper and lower sides of the head of femur. 217 x-rays of hips (65,56%) proved the existence of medial cervial osteophyte, according to frequency mostly type 1. Osteophyte of the roof of acetabulum were expressed on 158 x-rays (44,73). The double bottom of the acetabulum was studied on several measurement levels and showed from 0,24 to 2,35 mm observed from cranial to caudal measurement levels. The studies proved that the patients with coxarthrosis experienced a number of morphological and osteogenetic changes on the head and neck of femur as well as on the acetabulum. Their features on x-rays will depend on the cause and degree of the development of coxarthrosis.
