螺纹加压骨针固定治疗手部骨折的临床疗效

The clinical efficacy of pressurized bone needle on hand fracture fixation

目的探讨手部骨折螺纹加压骨针固定的疗效，为手部骨折患者的治疗提供数据支持。方法选取2010年1月-2014年1月接受治疗的126例手部骨折患者，按随机数字表法分为观察组63例和对照组63例；观察组使用螺纹加压骨针进行治疗，对照组采用常规克氏针固定法。对比两组患者治疗结果、并发症例数、早期松动和晚期松动情况、疗效情况及术中出血量、住院时间等指标和预后情况。结果观察组患者并发症例数、早期松动和晚期松动情况均显著优于对照组，组间差异有统计学意义（P〈0．05）；观察组治疗优良率（85．7％）显著高于对照组（63．5％），组间差异亦有统计学意义（P〈0．05）；两组术中出血量、住院时间等指标比较，观察组亦优于对照组，差异有统计学意义（P〈0．05）；观察组手部关节恢复好的例数显著高于对照组，差异有统计学意义（P〈0．05）。logistic回归分析发现，恢复效果与患者年龄、伤口异物以及手术时间存在明显负相关性，与抗菌药物的使用呈明显的正相关性。结论螺纹加压骨针治疗手部骨折疗效显著，特别是在治疗掌、指骨折中具有独到的优势，有利于患者的预后，是一种有效的治疗方式。

Objective To investigate clinical efficacy of pressurized bone needle on hand fracture fixation. Methods 126 patients of hand fractures were randomly divided into observation group （63 cases） and control group （63 cases）. The observation group was treated with bone needle. The control group was treated with conventional Kirschner wire fixation. The complications, the efficacy of the situation, blood loss, hospital stay indexes and prognosis were observed. Results The effect, complications in patients with early and late loose loose situation were different between observation group and control group （P〈0. 05）. The excellent effective rate of observation group and control group were 85.7 % and 63.5% （P〈0.05）. The blood loss and hospital stay of observation group were better than that of control group. The recovery effect was negative correlation with patient age, foreign bodies in the wound and surgery time and positive correlation with antibacterial drug use. Conclusion It is effective to treat hand fracture with pressurized bone needle, especially in treatment of palm and finger fractures.
