Toe-to-hand transfer for traumatic digital amputations in children and adolescents.
In the period from July of 1990 to August of 1994, 45 toe or toe tissue transfers were performed in 28 children and adolescents with traumatic amputation of digits. The average age at the time of transfer was 12 years (range, 3 to 16 years), and the median age was 10 years. The methods of reconstruction included transfer of 6 trimmed great toes, 2 great toe pulps, 24 second toes, 1 vascularized metatarsophalangeal joint from the second toe, 2 third toes, 4 combined second and third toes. and 1 combined third and fourth toes. All of the transferred toes, except one second toe, ultimately survived. Exploration and reanastomosis were required in three cases owing to arterial insufficiency. Partial pulp loss occurred in two digits. Follow-up ranged from 1 to 5 years (average, 3 years). Bony union occurred uneventfully in all patients. Two-point discrimination averaged 5 mm (static) and 6 mm (moving). Active range of the motion averaged 69, 38, and 13 degrees at the metaphalangeal proximal interphalangeal and distal interphalangeal joints of the reconstructed fingers, respectively, and 15 degrees at the interphalangeal joint of the reconstructed thumbs. None of the children required subsequent tenolysis. Pulp plasty was performed in nine digits in seven patients. Radiologically, the transferred phalanges showed the some growth as the non-transferred ones. Trimming the great toe before transfer did not result in premature physeal closure or growth retardation. The donor foot maintained a satisfactory appearance. None of the patients complained of difficulty in running or jumping. Toe-to-hand transfer in children, performed meticulously, can provide a valuable option for reconstruction of traumatic digit loss.
