[Thumb reconstruction with cryopreserved autogenous thumb skeleton and microneurovascular flap].

This paper describes a procedure for thumb reconstruction using autogenous cryo-conserved bone from the thumb itself. In a case of severe explosion injury, the thumb and index finger were amputated at the carpometacarpal joint level and the remaining fingers at the distal interphalangeal joint level. Severe soft tissue damage and lesion of both the superficial and deep palmar arterial arches rendered customary surgical procedures for thumb reconstruction impossible. The cryo-conserved bone was replanted following soft tissue healing and then covered with a free radial forearm flap. This procedure resulted in a stable and painfree thumb and provided satisfactory grip.
