Pushing the Limits in Extremity Reconstruction Using Virtual Surgical Planning: A Case Series Study.

Abstract

Technology is advancing in benefit to solving complex problems. Preoperative planning is essential in any reconstructive process given the importance of achieving good results. New technologies facilitate the process to anticipate intraoperative findings. Virtual surgical planning has contributed in the evolution of craniomaxillofacial surgery. However, limited reports have been published regarding its usefulness in extremity reconstruction. The aim of this study was to push the limits and evaluate the use of virtual surgical planning with three-dimensional images for reconstruction of complex extremity defects using a free, open-source software. Patient candidates for upper or lower extremity microsurgical reconstruction with multiple defects or defects requiring reconstruction of various tissue components were included. Computed tomography angiography images were analyzed for virtual surgical planning using Horos software (Horos, Annapolis, Md.). Two upper and eight lower extremities were reconstructed with free flaps using virtual surgical planning; six cases had multiple defects, and four cases underwent different tissue components reconstruction. The postoperative period was uneventful, and there was no flap failure. A didactic video of the process and examples of some cases are presented. Virtual surgical planning is a powerful planning method, and the authors propose its use in complex extremity defects reconstruction. Therapeutic, IV.
