VASCULARISED PERIOSTEAL TRANSFER – A SURGICAL TECHNIQUE TO ACHIEVE NEW BONE FORMATION IN TRAUMA

Abstract

It has long been recognised that the periosteal membrane has osteogenic capability and experimental studies have concluded that periosteum transplanted to a distant site could also be osteogenic. This ability of periosteum to generate new bone at distant sites may have clinical application. In the laboratory setting however periosteal flaps in animals have demonstrated variable results. Little clinical work using the technique of periosteal transfer has been reported, with only individual case reports in the literature.

A clinical review of a series of three fracture patients in whom vascularised periosteal transfer has been used is presented. Cases involved a primary bony defect at the fracture site (first metatarsal), established non-union (tibia) or post-traumatic AVN (talar dome). The technique is described and clinical follow-up of the patients is presented.

In each instance evidence of lasting new bone formation was demonstrated clinically and radiologically.

The efficacy of this technique in forming new bone is demonstrated. The technique may have utility alongside other techniques in cases where new bone is required.
