Abstract:
Objective To develop self-locking cannulated compression anti-rotation blade and investigate its design characteristic and manipulation techniques. Methods Femoral neck fracture model was made by osteotomy on seven cadaver femurs and then fixed by self-locking cannulated compres-sion anti-rotation blade under fluoroscopic guidance according to designed procedures. After fixation, bio-mechanic test was performed to evaluate fixation stability. Results Cannulated self-locking compres-sion anti-rotation blade was tightly impacted in proximal femur and compression detected during the process of locking, with successful manipulation and stable fixation. Conclusion Because of advanced design characteristic and simple manipulation, self-locking cannulated compression anti-rotation blade can be a substitute for cannulated cancellous lag screw in treatment of femoral neck fractures.
