Comparative Analysis between Dynamic Hip Screw and Cancellous Screw fixation for Fracture neck of femur

BACKGROUND: Fractures neck of femur are a common cause of morbidity and mortality in our community. Minimally displaced intracapsular fractures are treated with internal fixation by a dynamic hip screw (DHS) or three partially threaded cancellous screws. This prospective randomized controlled trial compares outcomes with these two fixation methods. METHODS: This is a prospective and retrospective study of 30 patients fracture neck of femur– 15 patients treated with dynamic hip screw and 15 patients treated with cancellous screw fixation. The study was done after getting clearance from Hospital ethical committee. Those who fulfilled the inclusion criteria given below, were invited to participate in the study. Informed consent was obtained from all the patients willing to take part in the study. Inclusion Criteria: Acute Fractures less than 3 weeks, Non comminuted fractures, Age above 16 yr and > 70 years. Exclusion Criteria: Age > 70 years and age < 16 years, Fracture duration greater than 3 weeks. CONCLUSION: In our study, patients treated with DHS had a higher union rate and lesser rate of complications. This may be attributed to several reasons: DHS produces a marked compressive effect leading to increased fracture healing and resistance to post-operative fragment spinning, we used a temporary second guide wire before lag screw insertion to control and minimize the rotation of the proximal fragment, the procedure of DHS fixation is simple when compared to cancellous screw fixation which needs surgical expertise. Hence from our study, we conclude that fracture neck of femur treated with Dynamic Hip Screw fixation gives results with a good functional outcome
