全螺纹钉加拉力螺钉内固定治疗股骨颈骨折的临床应用

Analysis of Clinical Effects of the Internal Fixation of Complete Thread Screw with Lag Screws for Femoral Neck Fractures

目的:观察分析全螺纹钉加拉力螺钉内固定治疗股骨颈骨折的临床疗效。方法:选取76例股骨颈骨折患者为研究对象,将所有患者随机均分为对照组(n=38)和观察组(n=38)。对照组患者行3枚半螺纹拉力螺钉内固定手术,观察组行1枚全螺纹空心螺钉加2枚半螺纹拉力螺钉内固定手术,其中全螺纹螺钉置于股骨颈后壁。所有患者手术后进行随访,采用Harris标准对髋关节康复情况进行评定。结果:治疗后,两组患者髋关节康复状况进行对比,观察组优良率高于对照组,差异具有统计学意义(P<0.05)。观察组中有7例股骨颈伴有后壁碎裂的骨折患者无股骨颈缩短、退针等并发症出现。结论:采用1枚全螺纹空心螺钉与2枚半螺纹拉力螺钉相结合的改进螺钉内固定方式,可以增强股骨颈骨折的稳定性,有效地控制股骨颈骨折愈合过程中的股骨颈缩短及退针等并发症,具有临床推广价值。

Objective To observe and analyze the clinical effect of treatment of femoral neck fracture with internal fixation with total screw and tension screw. Method 76 cases of femoral neck fracture were selected as the research object,all patients were randomly divided into control group （n = 38） and observation group （ n = 38 ） . The control group was operated with 3 lag screws while observation group was operated with 1 complete thread screw and 2 lag screws,and the complete thread screw was fixed in the back wall of femoral neck. All patients were followed up after surgery,and the hip joint rehabilitation was evaluated by Harris standard. Results After treatment,the two groups of patients with hip joint rehabilitation status were compared,the obser-vation group was better than the control group, the difference was statistically significant （ P 〈 0. 05 ） . In the observation group, there were 7 cases of femoral neck with fractures of the posterior wall of patients without femoral neck shortening,withdrawal and other complications. Conclusion Theinternal fixation method with 1 complete thread screw and 2 lag screws can improve the sta-bility, and effectively control the complications in the agglutination,which is an effective means of treatment and has clinical pop-ularization value.
