Retrograde intramedullary Huckstep nailing for supracondylar fracture of femur after total knee arthroplasty.

Supracondylar fracture of femur after total knee arthroplasty (TKA) presents a challenge for orthopedic surgeons. It is controversial to treat such a fracture by using closed method or open method. Nonunion, malunion, knee rigidity and other complications in prolonged immobilization were noted in the closed method. Implant migration, infection, nonunion and malunion were also reported in open reduction treatment because of the difficulty to achieve rigid fixation. In this periprosthetic fracture, retrograde intramedullary Huckstep nailing provides a better chance to get rigid fixation compared with other fixation device, especially in osteopenic bone. We reported 2 cases with supracondylar fracture of femur after total knee arthroplasty that have been successfully treated with retrograde intramedullary nailing.
