Abstract
Abstract: Autogenous bone constitutes the gold standard for grafting in oral and maxillofacial procedures. Tibial graft harvest has become an attractive alternative to iliac crest harvesting since it can be performed as an in-office surgical procedure, and since it provides comparably low complication rates and an acceptable graft yield. Unlike the iliac crest, the proximal tibia is primarily a load-bearing structure which transmits multiple body-weight loading on a repetitive basis. Despite the underlying concern regarding structural compromise at the donor site, no study to date has investigated the effect of graft harvesting on the compliance and structural integrity of the tibial plateau. This biomechanical study quantified the effect of geometrically defined graft harvest defects on the deformation of the tibial plateau under load.
