可膨胀髓内钉治疗肱骨干骨折的临床研究

目的通过对可膨胀髓内钉治疗肱骨干骨折的回顾性研究，探讨可膨胀髓内钉治疗肱骨干骨折的优势。方法我科2009年3月至2011年4月采用可膨胀髓内钉（Fixion系统）治疗肱骨干骨折17例。AO分形：A2型7例、A3型6例、B2型4例。手术时间：伤后2～7d，平均4．5d。均为闭合损伤，无血管、神经损伤。均采取闭合复位，顺行置入可膨胀髓内钉（Fixion系统）。本研究纳入病例均根据辩证结合中药治疗。结果所有患者术后获得7～13个月（平均9．8个月）随访。依据Neer评估标准，优9例、良5例、可3例。优良率82．3％。结论可膨胀髓内钉治疗肱骨干骨折具有微创、简便、并发症少等优点，是治疗肱骨干骨折简单，有效的方法，值得临床推广。
