A three-dimensional virtual reality model for limb reconstruction in burned patients

Abstract

Electrical burns are a common cause of injuries. Despite many developments in the treatment of high-tension electrical burns, this type of injury still shows high-morbidity rates. Recently, the use of free flaps for reconstruction in burned patients has increased due to advances in the field of microvascular free tissue transplantation [1]. Free flaps have reached a high level of sophistication. For instance, reexpanded flaps, composite tissue flaps, fascial flaps, multiple autologous flap transplantations and combined flaps (‘‘chimeric flaps’’) based on a single vascular pedicle have been performed in patients with severe burns and large defects in extremities [2]. Traditional methods of learning have helped generations of surgeons to familiarize themselves with flaps anatomy. Nevertheless, even texts with the highest level of accuracy and image quality are limited by the two-dimensional nature of printed material, which cannot impart three-dimensional (3D) views. Video material is similarly limited as to deliver a 3D experience. Another restriction of most traditional methods for the study of anatomy relates to the lack of interactivity and feedback. As a supplement to the knowledge gained from books and observation, cadaver dissections can play an
