During the period 1979 through 1986, 69 acetabular reconstructions in 63 pa
tients were performed with the use of autologous morcellized bone-grafts be
cause of acetabular bone stock loss. Nine cases (10 hips) were lost to foll
ow-up. Eleven patients (12 hips) died <10 years after surgery; none had a r
evision. The results for the remaining 43 patients (47 hips) were reviewed
at an average interval of 12.3 years (range, 10-17 years). No preoperative
Harris hip score was available. The average Harris hip store at follow-up w
as 88 (range, 60-100). Radiographically, all grafts united. One hip develop
ed a deep infection. Three other hips (6%) were revised because of aseptic
loosening of the acetabular component. An additional 3 acetabular component
s were considered radiographic failures. Excluding the infected case, the o
verall survival rate of these acetabular reconstructions with a revision as
endpoint was 94% at an average follow-up of 12.3 years. Reconstruction of
acetabular bone stock loss with autologous morcellized bone-grafts is an at
tractive technique with a good potential for long-term success.
