Functional and radiological outcome of surgical fixation of distal femur fractures by DFLCP: A prospective study

Abstract

Objective: To study the functional and radiological outcome of fracture of distal femur treated by open reduction and internal fixation with locking compression plate. Design: Prospective study Methods: Data collected for the study is from the patients admitted in orthopedic department in k r hospital, Mysore with distal femur fracture AO 33A, AO 33B and AO33C during the period of august 2016 to September 2018 treated with open reduction and internal fixation with distal femur locking compression plate with 4.5 system. All patients were followed up for an average of 12 months. Outcome was assessed by neer’s score. Results: of 36 patients (14 female & 22males), mean age was 43 years (18 to 62 years) 24 cases were high energy trauma and out of 24, 6 patients had type I compound wound as per gustillio Anderson classification and remaining 12 patients had trivial trauma. Out of 36 fractures treated, 33 fractures showed radiological signs of union within 6 months, remaining 3 cases showed delayed union which united completely by the end of 12 months.1 patient required bone grafting, 3 patients got infected, 2 implant failure, Mean range of motion of all patients were 110 degree. Conclusion: Open reduction and internal fixation of distal femur fractures with locking compression plate provides the good angular stability, prevents varus collapse and is gratefully helpful in osteoporotic patients. Best results are optioned when standard protocol of locking plate fixation is followed with good soft tissue care, early knee bending exercises and physiotherapy
