Osteosynthesis in digital replantation using bioabsorbable rods.
There are several fixation techniques for osteosynthesis in digital replantation. Kirschner wire fixation is used commonly but the wires protrude and disturb mobilization. Moreover, it requires removal. Since February 1995, the authors have been using a bioabsorbable rod made of poly-L-lactide as an intramedullary nail for osteosynthesis in digital replantation. The advantages of this technique include the absence of protruding hardware that would require removal and technical simplicity. This method has been applied for 15 arthrodeses (12 distal interphalangeal joints, 1 proximal interphalangeal joint, and 2 interphalangeal joints of the thumb) and for 11 diaphysis fractures (5 proximal, 5 middle, and 1 distal phalanx). All patients were observed until there was clinical and radiographic evidence of fusion (average interval to fusion, 8.4 wk). Bone resorption occurred in one patient. There were no cases of nonunion or infection. Poly-L-lactide rod fixation is a simple and effective technique.
