Grip reconstruction by double-toe transplantation in cases of a fingerless hand and a handless arm

In two cases, a grip reconstruction by double toe-to-hand transfer is demonstrated. In the first patient, all fingers of the left hand were amputated at the metacarpophalangeal joint level. The second and third fingers were reconstructed by transplantation of the second toe from the left foot and the third toe from the right foot. Although the distal and the middle phalanx of the transplanted third toe had to be amputated because of mummification 2 weeks after the transplantation and was covered with a groin flap, good function of the newly formed grip can be demonstrated. The second patient is a 21-year-old man with amputation of both hands at the wrist. A grip formation on the right lower arm was performed by transplantation of the second toe of each foot together with the metatarsal bone and a dorsalis pedis flap. Both metatarsal bones were fixed to the ulna and radius with metal plates, and tendons and nerves, together with a vascular supply, were reconstructed. One year after the operation, a follow-up study demonstrates good function of the newly formed "hand." The patient is able to use his two new "fingers" during daily life, mainly to hold small objects. A myoelectric prosthesis has been placed on the patient's left arm, and the patient uses this to hold bigger objects. Restoration of sensation and the range of movement of the newly formed right "hand" are demonstrated and discussed.
