PURPOSE: The authors have analyzed clinical and radiological results of the femoral neck fractures to evaluate the difference Knowles pin and cannulated screw fixation group. MATERIALS AND METHODS: The patients were devided into two group retrospectively, Group I included 35 cases that were treated with Knowles pin fixation for femoral neck fracture and Group II included 30 cases that were treated with cannuled screw fixation for femoral neck fracture. Clinical information included operation time, total blood loss and functional outcome. Postoperative X-ray information included Garden alignment index, duration of union and complication(P>0.05). RESULTS: There was no difference between the two fixation group regarding duration of union, functional outcome by Lanceford's method and complication(P>0.05). CONCLUSION: Knowles pin fixation and cannulated screw fixation were considered to be proper as a fixaton method in a fracture of the femur neck.
