Finger pulp reconstruction with free flaps from the upper extremity

Although never exceeding a few square centimeters, finger pulp defects are reconstructive challenges due to their special requirements and lack of neighboring tissue reserve. Local flaps are the common choice in the management of this injury. However, the development of microsurgery and clinical practice have greatly boosted the application of different free flaps for finger pulp reconstruction with excellent results, especially when local flaps are unsuitable or impossible for the coverage of large pulp defects. These flaps are all located in the same operation field and can be performed under one tourniquet; therefore, they are more convenient with better patients' compliance in clinical setting. Nonetheless, there is still no consensus about which type of these flaps should be preferred among various finger pulp reconstructive options. In this article, we attempt to review articles describing finger pulp reconstruction using free flaps from the upper extremity from the literature. We summarize the clinical applications of these free flaps and detail their advantages and drawbacks, respectively. The algorithm of flap selection for finger pulp reconstruction based on our experience and literature review is also discussed.
