[Cemented hip alloplasty. 11-13-year follow-up study of the Richards' series 2 hip prostheses].
The study comprises a follow-up (11-13 years) of an orthopaedic department's first 131 consecutive cemented total hip arthroplasties (THA). All operations were performed with Richards' Series 2. Posterior approach, plug, lavage, cementation with cement pistol, antibiotics and low-dose heparin. At the time of follow-up 44 patients (38%) were dead (= 49 THA), and 56 patients representing 65 THA (50%) were available for the follow-up, on average 11.95 years (11-13 years) after the operation. The patients hip/hips were examined as regards a) pain b) walking ability and c) hip-mobility (M. d'Aubigné) (HFI). A frontal x-ray of the pelvis and hip/hips was taken. The examining surgeon evaluated the hip/hips based on a clinical examination and the x-ray as 1 = stable, 2 = perhaps loose, 3 = most likely loose and 4 = definitely loose both with regard to the acetabular and femoral component. Pre-operatively 78% of the patients had an ideopathic coxarthrosis. Eight patients had considerable postoperative complications. Ten patients (7.8%) were reoperated during the examination period: two due to loosening of the total prosthesis, one due to loosening of the cup, three due to loosenings of the femoral component, two because of recurring luxations, one late (deep) infection and one fracture of the femur near the prosthesis. Preoperatively the patients' HFI was at 8.6, at follow-up 15.8. The clinical and the radiographic examination showed that 86% of the acetabular cups and 63% of the femoral components were fixed solidly.(ABSTRACT TRUNCATED AT 250 WORDS)
