摘要
目的探讨应用多轴锁定钢板内固定治疗中老年股骨颈骨折的可行性及近期疗效。方法回顾性分析2013年9月—2015年6月采用多轴锁定钢板内固定治疗的13例股骨颈骨折患者临床资料(A组),并与同期采用3枚倒"品"字形平行滑动加压空心螺钉内固定治疗的13例股骨颈骨折患者(B组)进行比较。两组患者性别、年龄、侧别、致伤原因、Garden分型、骨折部位分型、Pauwels角分型、Singh指数、受伤至手术时间、合并症等一般资料比较差异无统计学意义(P>0.05),具有可比性。比较两组患者术后1年颈短缩发生情况,末次随访时记录骨折不愈合、股骨头缺血性坏死发生率,并行髋关节Harris评分。结果两组患者均获随访,A、B组随访时间分别为(19.23±3.98)、(18.00±3.61)个月,差异无统计学意义(t=2.063,P=0.417)。随访期间A组未出现股骨头缺血性坏死;B组有1例发生股骨头缺血性坏死,二期行股骨头置换治疗;两组股骨头缺血性坏死发生率比较差异无统计学意义(χ2=0.000,P=1.000)。其余患者骨折均骨性愈合。末次随访时A组髋关节Harris评分为(85.23±2.95)分,显著高于B组的(81.92±3.64)分(t=2.064,P=0.018)。两组患者均未发生感染及内固定物切出等并发症。A组1例术后1个月出现大腿外侧酸痛,术后3个月基本缓解。术后1年A组均未发生股骨颈短缩,B组发生Ⅰ度短缩3例、Ⅱ度短缩2例、Ⅲ度短缩8例,两组比较差异有统计学意义(Z=–4.714,P=0.000)。结论多轴锁定钢板内固定治疗中老年股骨颈骨折相较于传统空心螺钉固定不显著增加股骨头坏死风险,在预防术后股骨颈短缩及改善功能方面有明显优势。
Objective 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. Methods 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 （P〉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.Results 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 between 2 groups （t=2.063, P=0.417）. No femoral head necrosis occurred in group A, but head necrosis occurred in 1 case of group B, and hemiarthroplasty was performed. There was no significant difference in the rate of femoral head necrosis between 2 groups （χ2=0.000, P=1.000）. Bone union was obtained in the other patients of 2 groups. The Harris hip score of group A （85.23±2.95） was significantly higher than that of group B （81.92±3.64） at last follow-up （t=2.064, P=0.018）. No infection or internal fixation failure occurred in 2 groups. One case had pain at the outer thigh at I month after operation in group A, but pain relief was achieved at 3 months after operation. At 1 year after operation, no femoral neck shortening occurred in group A, but degree I, II, and III femoral neck shortening was observed in 3, 2, and 8 cases of group B, respectively, showing significant difference between 2 groups （Z=-4.714, P=0.000）.
