Isolated third-toe transfer: Indications, technique, and reliability

Background: Isolated third-toe transfer is a versatile and safe technique when indicated. Methods: Between January of 1984 and January of 2003, 37 isolated third-toe transfers were performed in 31 patients. Results: Only one partial loss was noted among 37 transfers. There were 24 male and seven female patients, with an average age of 27.4 years (range, 7 to 43 years). Twenty-five patients received additional toe transfers. Secondary surgery was performed in 17 toes of 15 patients to improve the functional and cosmetic results. Patients were followed for 2 to 180 months (average, 36 months) and no significant donor-site morbidity was seen. Conclusions: Basically, the indications for isolated third-toe transfer are evaluated in two groups. Third-toe transfer is absolutely indicated when it is necessary for restoring basic hand functions in multiple-finger amputations. It is indicated because both second toes are transferred or the remaining second toe is adjacent to the previously transferred great toe. The other absolute indication is the unavailability of second toes because of trauma or deformity. Third-toe transfer is indicated relatively if it is used for additional reconstruction when basic hand functions are regained or already exist. Another relative indication is its better size match for proposed reconstruction. Second and third dorsal and plantar metatarsal arteries can be used as the pedicle artery for third toe-transfer; however, if second-toe transfer has already been performed or is planned, the third plantar or dorsal metatarsal artery should be used. Isolated third-toe transfer is a useful and reliable technique, especially in multiple-finger amputation reconstruction.
