U-T Flap for Distal Symes Toe Amputation. A New Flap Adapted to Diabetic Ulcers of the Pulp of the Lesser Toes

Abstract

The surgical management of diabetic ulcers of the tip of the toes complicated with osteomyelitis of the distal phalanx usually consists of the excision of the bone and soft tissue using a distal Symes toe amputation. This surgery is usually conducted through 2 coronal flaps. When the ulcer is away from the nail or extends further on the plantar side of the pulp, wound closure could be difficult to achieve resulting in wound dehiscence. In addition, the remaining toe is often too short when compared with the neighboring digits. The objective of this surgical technique is to propose a new flap design that could be simple and easy to learn, mainly when dealing with small-to-moderate–sized wounds. The U-T flap is designed to reduce wound complications and yield better esthetics. We found the U-T flap to be a reproducible technique with better outcomes in terms of surgical wound healing and final toe length, after excision of distal infected toes.
