Objective:
To compare the differences of bony union in autograft, allograft and their mixture-graft.
Methods:
The postoperative X-ray films of revision total hip arthroplasties with acetabular bonegraft were observed in 41 patients. They were women, aged at operation from 44 to 86 years (average 65 years). Follow-up ranged from 12 to 72 months (average 29 months). At the operation, autogenous bone was taken from the iliac-crest and homologous bone was from banked bone i.e. femeral head taken previously. Of these, 18 were autografts, 8 allografts, and 15 mixture-grafts. Bone incorporation was observed postoperatively on 6-week, 3-month, 6-month, 12-month and over 12-month films.
Results:
At 6 weeks, graft absorption appeared in 31% patients (13/41). At 3 months, bridging trabeculation across the graft-host interface was present in 88% patients, (36/41). At 6 months, graft remodelling began in 39% patients (16/41). At 12 months, graft remodeling was considered in 37 patients, and radiolucent prothesis in 4 (infection in 3 patients and graft absorption).
Conclusion:
No difference is observed in the time and the condition of bone union between autograft and allograft, autograft or allograft and their mixture graft.
