Introduction:Fractures of distal third femur may present difficulties in their treatment and require careful management to obtain good cosmetic and functional results. In recent years greater advances have been made in understanding the technique of internal fixation. Over the time different type of implants angle blade plate, rush rod, enders nail have been used for the fixation of these fractures. These devices are technically demanding and none of them can provide interfragmentary compression across intercondylar fracture surface. However it is documented that dynamic condylar screw can solve these problems with added advantages of early functional rehabilitation of knee, stable internal fixation and maintenance of joint congruity.
Aim: The study was conducted to evaluate the results of dynamic condylar screw in management of fracture distal third femur in adults, at the same time comparing the results with other studies.
Materials and Methods: The study was conducted on 30 patients of fractures of distal third femur treated by open reduction and internal fixation with dynamic condylar screw with a post operative follow up of one year. Releavant parameters like time of union, range of movements at knee and complication associated with these fractures treated with dynamic condylar screw were recorded. Schatzker and Lambert criteria were used to grade the result.
Results: Out of 30 patients, 26 (87%) were male and 4 (13%) were female. The cause of injury was road traffic accident in 27 (90%) cases. Average time of union was 15 weeks. In 21 patients (i.e. 70%) the range of movement of knee was 110° on above. Two patients (7%) had non union. There were 4 patients (13%) with knee stiffness and two (7%) with limb shorting up to 1.5cm. Infection was also noted in 2 patients (7%). The surgical outcome was excellent in 12 patients (40%), good in 9 patients (30%), fair in 5 patient (17%) and poor in 4 patient (13%).
Conclusion: The dynamic condylar screw is an easy, technically less demanding and effective method for treatment of fracture distal third femur.
