One bone forearm with vascularized fibular graft. Clinical experience and literature review

Abstract

One-Bone-Forearm (OBF) is a procedure in which the proximal stump of the ulna is fixed to the distal stump of the radius. Historically, the indications for OBF have been represented by forearm instability due to trauma, infection, tumor resection, and congenital deformities with severe radius and ulna bone loss. When major bone loss prevents direct fixation between ulna and radius a Vascularized Fibular Bone Graft (VFBG) may allow forearm bone reconstruction and fixation. In this study we report our clinical experience in 4 cases of OBF with VFBG performed in 3 patients. Compared to standard OBF technique with direct osteodesis, OBF with VFBG showed similar clinical results and high rate of healing even in case of bone infection. Moreover, composite osteocutaneous VFBG might concurrently allow to treat local soft tissue defects.
