THE STANMORE TOTAL HIP-ARTHROPLASTY - A 15 TO 20-YEAR FOLLOW-UP-STUDY

An ongoing study was made of 804 primary Stanmore total hip prostheses implanted in 839 patients between 1973 and 1991. The earliest survivi ng implants were brought back for radiologic and clinical review in 19 95 at an average of 17 years after surgery. The remainder of the patie nts still living were sent a questionnaire to assess their current sta tus. Survivorship was 95% at 10 years, 85% at 15 years, and 73% at 20 years. The average Merle d'Aubigne-Postel score was excellent up until 14 years. Patient satisfaction remained high until 22 years. Overall, 10% of the prostheses had failed. The results of this study suggest t hat the Stanmore prosthesis is capable of producing satisfactory long- term results that compare favorably with those of other cemented prost heses.
