[Tests for evaluating various methods of bone fixation in digital replantation]

Clinical results comparing different methods of bony fixation in 50 replanted digits in a series of 41 patients over a 13 year period are presented. The analysis was restricted only to replantantions involving sharp amputations of the proximal phalanx in order to restrict this study to a relatively homogenous group of patients. Evaluated techniques included: single and crossed Kirschner wire, intraosseous wire with or without Kirschner wire support, intramedullary splintage and intramedullary screws. Angulation deformities and delayed union were most common in cases treated with Kirschner wire technique. Nonunion was noted in 1 case (2%) stabilized with a single Kirschner wire. Angulation deformities were noted in 6 cases (12%). No such complications were noted in cases treated with intramedullary splintage and intramedullary screws. The best stabilizing effect and the most rapid union was noted in cases treated with intramedullary screws.
