Abstract


Background: Distal femur fractures are high velocity injuries which accounts for 7-10% of all femoral fractures. These injuries are complex injuries which are difficult to manage. Despite advances in techniques and implants, treatment remains a challenge, in many situations.

Methods: We present a retrospective review of 8 cases, involved in high velocity road traffic accident who presented to emergency department at St. John’s Medical College, Bangalore, Karnataka, India between September 2011 to December 2015, with complex open fracture of the distal femur with bone loss. All were managed with initial wound debridement and skeletal traction. Subsequently fractured femur was reconstructed with distal femoral locking plate stabilization, along with autogenous non vascularised fibular graft and cortical-cancellous graft bridging the bone defect. Radiological union, functional outcome measured with Tegner and Lyslom scores, KOOS score and complications were assessed.

Results: At average 5 years follow up, all the fractures have united well, with good functional outcome. X-ray showing united fracture with incorporation of the fibular graft. According to Tegner and Lyslom scoring, 6 patients had good rating, 2 had satisfactory rating. Average KOOS score was 82.15. Shortening of 2 cm and 4 cm in couple of patients was the major complication.

Conclusions: Delayed primary surgery, using autologous non vascularised free fibular graft in conjunction with a locking compression plate, with autogenous cortico-cancellous graft is an effective, less technically demanding and cost effective means of reconstruction option to manage bone defects in complex open fractures of the distal femur. An overall acceptable results in terms of fracture union, fibular incorporation, adequate restoration of knee motion and early rehabilitation can be expected.
