CUMULATIVE REVISION RATE WITH THE SCAN HIP(R) CLASSIC-I TOTAL HIP-PROSTHESIS - 1,660 CASES FOLLOWED FOR 2-12 YEARS

We analyzed the cumulative revision rate in 1,474 patients (1,660 hips ) operated on with a cemented Scan Hip(R) Classic I prosthesis from No vember 1983 to January 1994 at Lund University Hospital. The revision rate was analyzed for 3 diagnoses-arthrosis, rheumatoid arthritis and complication after a hip fracture-and for 2 head diameters-22 and 32 m m. Until January 1996, 36 hips were revised: 31 because of aseptic loo sening, 3 because of dislocation and 2 because of infection, The overa ll revision rate was 5.6% after 10 years and was similar in arthrosis, rheumatoid arthritis and fracture cases. Due to revisions because of dislocation in the 22 mm group, the total revision rate was lower in t he 32 mm group (p = 0.03).
