title: Microsurgical replantation of a small segment of thumb volar skin.
abstract: This report presents a case of microsurgical replantation of a volar skin segment of the thumb. In a 24-year-old patient, a heavy object falling over the dominant thumb resulted in a crush-avulsion injury of a pure skin segment measuring 4 x 2 cm. Examination revealed that the distal fingertip as well as the bone-tendon structures remained intact. Exploration demonstrated that both neurovascular bundles were included in the avulsed skin segment. Microsurgical replantation was achieved successfully, repairing the radial digital artery at both ends with vein grafts as well as anastomosing a palmar vein. Both digital nerves were coapted proximally and distally. An excellent functional and cosmetic result was accomplished with a good sensory recovery. The authors conclude that microsurgical replantation should be attempted in cases of more proximal pure skin avulsions, even if the injury spares distal fingertip tissue or bone-tendon units. In such cases, replantation is superior to any other method of reconstruction. Liberal use of vein grafts is crucial to achieve success.
