Use of Resorbable Fixation for Posterior Cranial Vault Distraction Osteogenesis.

Abstract

Posterior vault distraction osteogenesis traditionally relies on the use of cranial distractors affixed with titanium screws to the posterior cranial vault transport segment to allow for expansion of intracranial volume. The authors describe a novel technique using the resorbable fixation Synthes Rapidsorb Injectable Polymer System for stable fixation of the distraction hardware for posterior vault distraction osteogenesis. In a retrospective review of their experience with the system, there was no instance of hardware or fixation failure. This off-label use of Rapidsorb system resulted in a significant reduction in operative time for hardware removal and allowed for a more limited dissection, which can help reduce the incidence of devascularization of the bony regenerate, bony relapse, and other complications.
