[Study on early repair of destructive hand injury and reconstruction of hand function].

OBJECTIVE

To investigate a clinical method in repairing destructive hand injury and reconstructing hand function in early stage.

METHODS

From January 1990 to June 1999, composite tissue transplantation was used to repair destructive hand damage and reconstruct hand function with vascular anastomosis in emergency (33 cases) or subemergency (126 cases). For the radial damage, combined flaps with toes was used to treat cicatricial contracture of thumb-web space. Opposing function of thumb was reconstructed by combined transplantation of short extensor muscle of great toe, short extensor muscle of toes or short abductor muscle of great toe in the same time of freeing the second toe. For no or deficient anastomosing vessels in donor site, "Y"--shaped reversal vein, anterograde bridging, or branches bridging of host vessels were applied.

RESULTS

All of tissue transplantation were survived, including combined tissue transplantation in 51 cases, composite tissue transplantation in 4 cases, tissue transplantation after replantation of severed wrist and finger in 4 cases, there were no infection or necrosis in all cases, and hand function recovered well.

CONCLUSION

It is an ideal procedure to repair destructive hand injury and reconstruct hand function by combined or composite tissue transplantation with vascular anastomosis in emergency or subemergency.
