Replantation of articular composite tissue masses severed from extremities

SummaryThe techniques and outcomes of in situ replantation are discussed for managing 5 cases of articular composite tissue masses severed from an extremity (digit). All 5 cases treated with in situ replantation survived. Rehabilitation was performed after surgery. Follow-ups of 2–5 years showed good appearance, satisfactory functional and sensory recovery. In situ replantation is indicated for an articular composite tissue masses severed from an extremity (digit), if its structure is complete and a blood supply vessel in the mass is available for anastomosis. Replantation can achieve better outcomes than transfer or grafting of adjacent skin or osteocutaneous flaps, or transplantation of a metatarsophalangeal or interphalangeal joint.
