Comparison of autograft and allograft fixation in Pemberton osteotomy.

UNLABELLED: This retrospective study compared the results of autograft and allograft fixation in 29 children (36 hips) who underwent Pemberton osteotomy. Autograft fixation was used in 21 hips and allograft fixation was used in 15 hips. In the autograft group, 76% of patients had a successful result; 4 of 8 of patients with a neuromuscular disorder in this group had a successful result. In the allograft group, 93% of patients had a successful result; 6 of 7 of patients with a neuromuscular disorder in this group had a successful result. Pemberton osteotomy performed with allograft fixation provided similar or better results than autograft, especially in children with neuromuscular disorders. LEVEL OF EVIDENCE: diagnostic study, Level III-2 (retrospective cohort study).
