Comparison of osteoporotic intertrochanteric fracture fixation using a proximal femoral nail with a helical blade and lag screw type proximal femoral nail
Abstract:The aim of the study was to compare clinical and radiological results between the helical blade lag screw (proximal femoral nail antirotation II [PFNA II]) and the traditional lag screw (Zimmer Natural Nail [ZNN]) in the operative treatment of osteoporotic femur intertrochanteric fractures. We selected 182 patients who could be observed for at least 1 year from among 352 patients who received surgical treatment for osteoporotic isolated femur intertrochanteric fractures between January 2013 and December 2016. … Show more
