RESUMO
Background: Among diabetics, patients with peripheral neuropathy are at increased risk of developing complications following an ankle fracture. While the outcomes in these patients treated nonoperatively have been poor, the outcomes in those undergoing open reduction and internal fixation are at the best modest. We hypothesize that closed reduction and internal fixation with tibiotalocalcaneal nail is an effective primary procedure in this complication prone patient group. Methods: A retrospective review of diabetic patients with peripheral neuropathy who underwent acute treatment of an ankle fracture with closed reduction and internal fixation with a tibiotalocalcaneal nail at two Level 1 trauma centers was performed. 30 patients were identified and divided into 2 groups with respect to their postoperative weight bearing protocol: 20 patients in the early weight bearing (EWB) group and 10 patients in the touch-down weight bearing (TDWB). The primary outcome was the rate of return to baseline function and the secondary outcomes included the incidence of wound dehiscence, wound infection, implant failure, loss of fixation, loss of reduction and amputation. Results: In the EWB group, 15/20 patients returned to their baseline function, 5/20 had wound dehiscence and infection, 2/20 had implant failure, 5/20 had loss of fixation, 4/20 had loss of reduction, and 4/20 underwent amputation. In the TDWB group, 9/10 patients returned to their baseline function, 1/10 had implant failure, 1/10 had loss of fixation. No patients from this group had loss of reduction or underwent amputation. Conclusion: Treatment with tibiotalocalcaneal nail is an effective primary procedure in this complication prone group of patients, assuming that weight bearing is delayed for six weeks to protect soft tissues and surgical incisions. Level of Evidence: Level IV, retrospective case series.
