Short-term effectiveness of polyaxial locking plate for fixation of femoral neck fracture in middle-aged and elderly patients

To evaluate the feasibility and short-term effectiveness of polyaxial locking plate for fixation of femoral neck fracture in the middle-aged and elderly patients. A retrospective analysis was made on the clinical data of 13 patients with femoral neck fracture undergoing fixation with polyaxial locking plates between September 2013 and June 2015 (group A) and 13 patients with femoral neck fracture undergoing fixation with three cannulated screws in the same period (group B). There was no significant difference in gender, age, side, cause of injury, Garden type, type of fracture position, type of Pauwels angle, Singh index, time between injury and operation, and preoperative complications between 2 groups ( >0.05). The femoral neck shortening at 1 year postoperatively, and fracture nonunion, femoral head necrosis, and Harris hip score at last follow-up were compared between 2 groups. The follow-up time was (19.23±3.98) months in group A and (18.00±3.61) months in group B, showing no significant difference betwe
