Soft Tissue Management of Partial Hand Amputation

Abstract

Conventional teaching in the management of partial hand amputations prioritizes residual limb length, often through local, regional, or distant flaps. While multiple options exist to provide durable soft tissue coverage, only a few flaps are thin and pliable enough to match that of the dorsal hand skin. Despite debulking, excessive soft tissues from previous flap reconstructions can interfere with residual limb function, prosthesis fit, and surface electrode recording for myoelectric prostheses. With rapid advances in prosthetic technology and nerve transfer techniques, patients can achieve very high levels of function following prosthetic rehabilitation that rival, or even outpace, traditional soft tissue reconstruction. Therefore, our reconstruction algorithm for partial hand amputations has evolved to the thinnest coverage possible, providing adequate durability. This evolution has provided our patients with faster and more secure prosthesis fitting with better surface electrode detection, enabling earlier and improved use of simple and advanced partial hand prostheses.
