RESUMEN
PURPOSE: To evaluate bioabsorbable poly-DL-lactic acid (PDLLA) intramedullary rods for fracture fixation of amputated digits. METHODS: From October 2005 to October 2007, we used bioabsorbable rods made of PDLLA as intramedullary fixation in osteosynthesis procedures in 9 cases of digital replantation. Four cases involved the middle phalanx and 5 the proximal phalanx. The amputation level was diaphyseal in all cases. All patients were followed up from 6 months to 2 years, with an average of 13 months. RESULTS: All fractures healed in 6 to 8 weeks. There were no infections. There was no evidence of hardware failure at 4 weeks after surgery. According to the Tamai et al criteria, the results were excellent in 8 cases and good in 1. CONCLUSIONS: Using bioabsorbable PDLLA rods for intramedullary fixation can be an effective technique for replantation with fractures through the proximal or middle phalanges. Bioabsorbable rods can provide rigid stable fixation, which allows early mobilization.
