The 3D-Printed Titanium Truss Cage for the Treatment of Concurrent Complex Malunion, Synostosis and Large Bone Defect Following Forearm Injuries: A Case Report

Abstract

A 28-year-old man sustained a complex forearm injury from high-energy trauma, causing ulnar nerve injury, a bone defect, forearm malunion and synostosis. A 3D-printed titanium truss cage was used to solve these problems. This patient achieved union of the bone defect, was pain-free and had no recurrent synostosis 2 years after reconstructive surgery. The advantages of the 3D-printed titanium truss cage included anatomical fit, immediate mobilisation and low morbidity of the donor side of the bone graft. This study reported a promising result from using 3D-printed titanium truss cages to manage complex forearm bony problems. Level of Evidence: Level V (Therapeutic)
