切开复位克氏针或锁定钢板内固定治疗肱骨外科颈骨折的疗效观察

The effects of opening eduction kirschner wire or locking plate internal fixation in the treatment of humerus surgical neck fracture

目的探讨肱骨外科颈骨折克氏针内固定和锁定钢板内固定两种方法的疗效。方法对75例肱骨外科颈骨折患者进行随机分组,其中克氏针组38例,锁定钢板组37例,对两种内固定方法进行分析。结果两组骨折愈合时间比较,差异有统计学意义(t=9.7087,P<0.05)。采用Constant评分标准,克氏针组与锁定钢板组的优良率分别为73.7%和91.9%,差异有统计学意义(χ2=4.337,P<0.05)。结论克氏针内固定治疗肱骨外科颈骨折创伤小,骨折愈合时间短;但锁定钢板内固定治疗整体效果好,固定牢固,畸形愈合少。

Objective To explore the efficacy of opening eduction kirschner wire and locking plate internal fixation in the treatment of humerus surgical neck fracture. Methods A total of 75 patients with humerus surgical neck fracture were randomly divided into two groups,38 patients in treatment group （kirschner wire）and 37 patients in control group, analyzing the clinical datas of two methods of internal fixation. Results Comparing two groups of healing time of fracture, the differences were statistically significant （t = 9.7087, P 〈 0.05）. By the Constant grading standards, total excellent rate in observation group was 73.7%, was significantly lower than the control group（91.9%）, the differences were statistically significant （χ2=4.337,P 〈 0.05）. Conclusion Kirschner wire fixation in the treatment of humerus surgical neck fracture has the advantages of small trauma and shorting the fracture healing time;but the locking plate internal fixation treatmenthas has the advantages of being fixed firmly and less malunion, the overall effect is good.
