英文摘要 | Between 1979 and 1994, 1 had experienced 2,743 hips in 2,276 patients undergoing total hip arthroplasty (THA). The mean age at operation was 50.8 years (range 17-89 years). More than 90% of the hips were cementless. Male was much more than female (1.5/1). The causes for THA were osteonecrosis 39.8%, osteoarthritis 31.6%, revision 18.7%, ankylosing spondylitis 3.5%, rheumatoid arthritis 1.9%, etc.. There were several types of prostheses used, including ceramic 7.9%, Roy Camille and Mecron 11.1%, PCA 28.1%, Osteonics 51.1%. There were 1,920 hips in 1,568 patients followed up for more than 2 years (2-17 years, average 8.5 years). Excellent and good clinical results achieved 84.8% according to our rating system (radiological + Clinical). Maro-intemloding typers of prosthes (eg. Ceramic, Roy Camille, and Mecron) had less satisfactory result (56%) than that of biological fixation types (e.g. PCA and Osteonics, 91%). About 91% of the patients after THA had pain free or mild pain. Total loosening rate was 12.3% and revision rate, 9.7%. The revision rate was higher in macro-interlocking group 27.6% (ceramic 15.6%, Roy Camille + Mecron 35.5%), but relatively lower in biological fixation group 4.9% (PCA 7.8%, Osteonics 3.9%). The overall occurrence of osteolysis was 15.9%. Other complications were: dislocation (5.4%), deep infection (0.7%), nerve palsy (0.3%), and ectopic ossification (1.3%) . In conclusion, the invention of THA had a great contribution for the human beings who had disable hip diseases, but still created other new problems. New biomaterials and new designs of prostheses to reduce stress shielding and wear, together with the decrease of patient's activity were the key points for the longevity of THA. |
