  • Short-term effectiveness of femoral neck system in the treatment of femoral neck fracture

    ObjectiveTo investigate the short-term effectiveness of femoral neck system (FNS) in the treatment of femoral neck fracture.MethodsThe clinical data of 34 patients with femoral neck fracture admitted between January 2019 and April 2020 who met the selection criteria were retrospectively analyzed and divided into group A (19 patients were treated with conventional cannulated screw internal fixation) and group B (15 patients were treated with FNS internal fixation) according to the different methods of internal fixation. There was no significant difference between the two groups in general data such as gender, age, affected side, cause of injury, fracture type, and time from injury to operation (P>0.05). The operation time, intraoperative blood loss, fluoroscopy frequency, and fracture healing time were recorded and compared between the two groups. X-ray film and CT examinations were performed postoperatively to evaluate fracture reduction and internal fixation, and the shortening of the femoral neck on the affected side was measured compared with that on the healthy side. The Harris score was used to evaluate hip function.ResultsThere was 1 unsatisfied reduction case in groups A and B respectively, the rest of the patients in both groups were obtained satisfied reduction. There was no significant difference in the quality of reduction between the two groups (Z=–0.195, P=0.854). There was no significant difference in operation time between the two groups (t=0.649, P=0.064). The intraoperative blood loss in group A was significantly less than that in group B, and the fluoroscopy frequency was significantly more than that in group B, with significant differences (P<0.05). Except for 1 case in group A with screw out at 3 months after operation and no obvious callus formation, all fractures in the two groups reached clinical healing, and there was no significant difference in fracture healing time between the two groups (t=–0.127, P=0.899). There was no necrosis of femoral head in the two groups. At last follow-up, there were 4 cases of femoral neck shortening in group A and 2 cases in group B. The hip function of both groups recovered well, and there was no significant difference in Harris score at last follow-up (t=0.956, P=0.346).ConclusionThe treatment of femoral neck fracture using FNS has less trauma. Compared with cannulated screw internal fixation, it can reduce the intraoperative fluoroscopy frequency and obtain satisfactory short-term effectiveness.
