COMPARATIVE STUDY OF INTERNAL FIXATION BY DIFFERENT IMPLANTS IN DISPLACED FRACTURED NECK OF FEMUR IN ADULTS

Treatment of fracture neck of the femur depends mainly upon the viability of the head of the femur and internal fixation remains the method of choice if head is viable. A total of 61 patients satisfying the inclusion criteria were allotted to the two treatment groups, either a cannulated cancellous screw system(CCS) or a dynamic hip screw with antirotation screw (DHS-AS).The two procedures were compared for the time taken for union and complications like osteonecrosis and non-union. Follow-up was done at 6 weeks, 3 months, 6 months and then 6 monthly for a maximum of 2 years. Rate of osteonecrosis was comparable for both procedures but non-union was significantly higher in patients treated with CCS and those with Pauwel’s type III fractures. By 6 months 83.61% of patients had achieved union. For CCS cases it was 70.97% and for DHS-AS it was 96.67% at 6 months follow up.
