The hemispherical Harris-Galante acetabular cup, inserted without cement -The results of an eight to eleven-year follow-up of one hundred and sixty-eight hips

We studied the results for 168 available hips from a series of 324 consecut ive primary total hip arthroplasties that had been performed with insertion of a Harris-Galante-I acetabular component without cement. The acetabulum had been reamed in a so-called line-to-line manner, acid the cup had been f ixed with one to four screws. A femoral component with a modular alumina-ce ramic head had been inserted with cement in all hips. The median duration o f follow-up was 112 months (range, 101 to 131 months). Of the original 324 hips, 109 could not be included in the clinical and rad iographic follow-up because the patients had died and thirty could not be i ncluded because the patients were not available for examination. Seventeen hips had had a revision of the acetabular cup: five, because of infection; five, because of dislocation; three, because of aseptic loosening; and four , because of technical failure. This left 168 hips for clinical and radiogr aphic follow-up; of these, fifteen had had a revision of the femoral compon ent only. Of the remaining 153 hips, which had not had a revision, 147 (96 percent) were considered by the patient to have a satisfactory, good, or ex cellent result, One hip was found to have a loose cup on radiographic evalu ation and was therefore considered to have failed, but the clinical functio n was good. We concluded that, with an overall rate of aseptic loosening of 1 percent ( four of 324) after an intermediate (ten-year) duration of follow-up, use of this cup has good results.
