Revision surgery in high grade acetabular defects with thermodisinfected allografts.

Aim: Due to new medical knowledge and legal restrictions, it is increasingly difficult to run a traditional allogenic bone bank so that alternative bone substitutes and methods of processing are being sought worldwide.

Method: In a prospective clinical study, the biological efficacy of thermodisinfected and then cryopreserved allogenic bank bone was investigated in 19 acetabular revisions in 18 patients. Simultaneously a newly developed titanium reconstruction ring was used.
