HGP 인공고관절 전치환술에 대한 임상적 고찰

Abstract

Authors studied and analyzed 48 patients (51 hips) who received the Harris-Galante type noncemented total hip replacement since 1984. The average follow up was three years. 1. There were 37 male (40 hips) and 11 female (11 hips). The average age was 50 years ranging from 24 to 71 years. 2. the causes were avascular necrosis in 40, femur neck fractures in 7, and osteoarthritis in 4 hips. 3. The only intraoperative complication was a calcar crack in one hip. Postoperative complications were one dislocation and five greater trochanter detachments. 4. We found the radiodense line around the femoral stem in 25 hips, the radiodense line around the acetablar cup in 15 hips and sclerosis around the femoral stem tip in 18 hips. 5. The average preoperative Harris-Score was 44.8 points (range, 10-76 points) and imp¬roved to 93.6 points (range, 73-100) points at the last follow up. 6. Postoperative hip pain occurred in 7 hips. The pain character was an intermittent inguinal and greater trochanter pain, and mostly appeared after long distance walking. In addition, thigh pain occurred in 6 hips and knee pain was seen in 1 hip. 7. Early clinical results of HGP total hip replacements are excellent in 43 hips and good in 7 hips at average of 36 months.
