From 1979 to 1987, 55 total hip replacement operations performed on 51 patients with acetabular roof deficiency. The deficient acetabular roof was reinforced laterally with an autogenous bone graft from femoral head in 50 hips and with the iliac cortico-cancellous bone graft in 5 hips. All the bone graft were united well at the followup of 12 to 77 months (mean 29 months). There were three compications. One had early dislocation 3 days post-operatively. The other had late dislocation 2 years and 4 months after operation. Another one had aseptic loosening of the cup and femoral component three years and ten months later. However, they all got solid union eventually. With the numerical functional assessment (Table 2), the result got dramatical improvement from 29% to 94.6% good to excellent (Table 3). No statistic significance in hip score was noted between the cemented and noncemented groups (P>0.05) (Table 4). Absorption of lateral part of the bone graft was found in 37(67.3%) hips. We could find graft absorption was not a function of time and there was also no evidence of progressive radiolucency or graft absorption in this series.
