The Use of Resorbable Fixation for Posterior Cranial Vault Distraction Osteogenesis

Abstract

Summary: Posterior vault distraction osteogenesis (PVDO) 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. We describe a novel technique using the Synthes RAPIDSORB IPS resorbable fixation system for stable fixation of the distraction hardware for PVDO. In a retrospective review of our experience with the IPS system, there was no instance of hardware or fixation failure. This off-label use of the IPS system results in a significant reduction in operative time for hardware removal while allowing for a more limited dissection, which can help reduce devascularization of the bony regenerate, bony relapse, and other complications.
