Intramedullary Fixation of Calcaneal Fractures: Early US Experience

Abstract

Category: Hindfoot; Trauma Introduction/Purpose: The fixation of displaced intraarticular fractures of the calcaneus have posed many challenges for the surgeon, including an anatomic reduction, fracture stabilization, and soft tissue concerns. The extensible lateral and sinus tarsi approaches must be delayed until soft tissues concerns resolve and despite this are susceptible to wound necrosis and skin infections. Intramedullary fixation allows immediate fixation without soft tissue compromise. Methods: The retrospective case series is comprised of 23 patients; 19 intramedullary fixation of the calcaneus and 4 primary arthrodesis with the FH Orthopedics CalcaNail. Fracture classification, timing to surgery, accuracy of reduction, complications, and outcome were recorded. Results: There were zero wound complications. Bohler’s angle was restored as well as articular surface. One patient required implant removal after healing seconding to prominent hardware. One patient required conversion to a subtalar arthrodesis. There were no implant mechanical failures. Conclusion: The intramedullary fixation of calcaneus fractures has been performed extensively outside the US with documented success. This series of early US experience exhibits similar utility. The ability to reduce the fracture intrafocally and stabilize with a minimally invasive approach have proven useful with no incidence of wound complications. Not to mention no delay from time of injury to surgery is needed.
