【摘要】：[目的]比较多枚空心螺钉与动力髋螺钉(DHS,Dynamic Hip screw)内固定治疗股骨颈骨折的疗效。[方法]2013年2月~2016年3月共收治67例股骨颈新鲜骨折患者,58例获得随访。其中男24例,女34例;年龄22~65岁,平均43.2岁。多枚空心螺钉固定35例,DHS固定23例。根据骨折Garden分型,其中空心钉组GardenⅠ型9例,Ⅱ型12例,Ⅲ型10例,Ⅳ型4例;DHS组Ⅰ型2例,Ⅱ型4例,Ⅲ型11例,Ⅳ型6例。记录手术时间,术中出血量,输血情况,二次手术,并发症发生率,髋关节功能Harris评分。[结果]平均随访25.6个月,两组术后切口均一期愈合。手术时间空心钉组平均(39.57±12.96)min,DHS组平均(48.06±13.04)min,出血量空心钉组平均(20.86±25.2)ml,DHS组平均(65.43±37.9)ml,差异均有统计学意义(P0.05)。输血例数空心钉组5例,DHS组3例,差异无统计学意义(P0.05)。空心钉组骨折愈合时间平均(14.11±6.34)周,DHS组(9.39±1.95)周,差异有统计学意义(P0.05)。末次随访空心钉组和DHS组Harris评分分别为(91.2±11.16)分和(95.39±3.07)分,差异无统计学意义。空心钉组有3例(8.57%)股骨头缺血坏死,1例(2.86%)进行髋关节置换。DHS未发现股骨头缺血坏死病例。空心钉组18例(51.43%)存在股骨颈短缩,其中14例(40%)因螺钉突出不适要求行内固定取出;DHS组6例(26.09%)存在轻度股骨颈短缩,无因内固定物突出原因要求取出内固定者。[结论]空心钉和DHS治疗股骨颈骨折都可获得较高的骨折愈合率,DHS固定具有骨折愈合快,股骨颈短缩发生率低,再次手术率低的优点。
[Abstract]:[objective] to compare the efficacy of multiple hollow screws and dynamic Hip screwfixation in the treatment of femoral neck fractures. [methods] A total of 67 cases of fresh fracture of femoral neck were treated from February 2013 to March 2016. 58 cases of fresh fracture of femoral neck were followed up. There were 24 males and 34 females, aged 2265 years, with an average age of 43.2 years. 35 cases were fixed with multiple hollow screws and 23 cases were fixed with DHS. According to the Garden classification of fracture, there were 9 cases of Garden type 鈪，
