| Abstract: | When a functionally important digit is injured as part of a multiple digit injury, transpositional digital replantation is worth considering to preserve greater hand function and to avoid or minimize the necessity for secondary reconstructive procedures. We present two such cases with transpositional digital replantation. The indications for this technique are: 1) multiple digit injury, 2) severe crush injury, 3) the possibility of preserving more and better joints in some fingers, and 4) injury distal to Tamai's zone V (11). The benefits of this procedure are that function can be better with the more completely preserved digits replanted into the most useful positions and of similar lengths. Difficulties are encountered when there are large discrepancies in size of surviving digits, and problems with soft-tissue coverage, tendon repair, a 'step' at the fracture site after bone fixation, and with vessel anastomosis. Use of this procedure can result in preservation of hand function and fewer secondary reconstructive procedures. |
