Long-term effects of toe transfers on the donor feet.

The purpose of this study was to assess the long-term consequences to the donor site of microvascular transfer of one or two toes. This was achieved retrospectively by patient-reported, clinician-based and functional testing. Weight-bearing radiographs were taken of both feet. Seventy-four patients (80 feet, 84 transferred toes) participated in this study. After a median of 16 years follow-up, most patients reported no or only minor complaints concerning the donor site. Cold intolerance and pain during exertion were the most commonly reported complaints. According to the two functional scores used, 92% of patients reported no or minor complaint and 83% of patients received a good result at the donor feet. Maintaining first ray alignment and avoiding early postoperative complications predicted a better outcome. Even though donor site ramifications should be expected after microvascular transfer of toes, patient satisfaction remains high.
