Objective: To evaluate the clinical outcomes and radiological union of distal third femur fractures by using distal femur locking plate, in Zagazig university hospitals and KafrSaad emergency hospital. Design: Clinical trial. Methods: Data collected for the study was from the patients admitted in orthopedic department in Zagazig university hospitals and KafrSaad emergency hospital, with distal femur fracture AO 33,during the period of August 2019 to July 2020 and 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 6 months. Outcomes were assessed by Neers score. Results: Outof 12 patients (4 were females&8were males), mean age was 45.6 years (20 to 70 years). 10 cases wereduo to high energy trauma and 2 cases wereduo to low high energy trauma.5 out of total 12 cases had open fractures and rest 7 cases had closed fractures.Out of total 12 cases, five cases were extra-articular and rest 7 cases were intra-articular. Out of 12 fractures treated, 8 fractures showed radiological signs of union within 12-16 weeks,3 fractures showed radiological signs of union within 20 weeks and one fracture showed radiological signs of union within 24 weeks.1 patient got superficial infection and no implantfailure, mean range of motion of all patients was 113°. Conclusion:ORIF of distal femur fractures with locking compression plate provides good angular stability, restoration of limb alignment, length, rotation and give a good purchase in osteoporotic patientswith minimal complications. Best results are optioned when standard protocol of locking plate fixation is followed with good soft tissue care, early knee bending exercises and physiotherapy.
