Objective To explore the effect and clinic value of appplying cannulated screws on medial humeral epicon-dyle fractures. Methods From August 2005 to March 2012,15 consecutive patients(male 13,female 2;right elbow 11,left elbow 4;mean age 16 years;range 11 to 23 years) suffered from medial epicondylar fractures were treated with cannulated screws in open reduction and internal fixation(ORIF). All patients had medial humeral epicondyle fractures with displacement >1cm or had epi-condyle fractures accompanying elbow dislocations and with entrapment of the fragments in the elbow joint after manipulative reduc-tion of elbow dislocation. Of the 15 patients, 7 complicated with elbow dislocation and 1 had ulnar nerve disfunction syndrome. The duration time between the injury and operation ranged from 3 to 6 days. All the patients were followed up and evaluated. The outcome was evaluated by bone union and elbow function. Results All cases were followed up for 13-24 months with an average of 15 months. All the incisions were healed primarily and there were neither failures of the implantation divices nor early physeal growth cessations. All patients had union of the medial epicondyle with the mean healing time of 10 weeks and there were no avas-cular necroses ( AVN) of bone. According to Mayo Elbow Performance Score ( MEPS) for the function of elbow joint, among these 14 cases was excellent, 1 was good. Conclusion ORIF with cannulated screws is an ideal surgical method for treatment of medial humeral epicondyle fractures with larger than 1cm of displacement or with fragment being entrapped in the joint.%目的 探讨空心螺钉治疗肱骨内上髁骨折的临床疗效及应用价值. 方法 回顾性分析我院收治的采用空心螺钉治疗的15例肱骨内上髁骨折患者资料. 所有患者均骨折块移位大于1cm或伴有肘关节脱位并且复位后骨折块嵌顿在关节间隙中,即Ⅱ度~Ⅳ度肱骨内上髁骨折. 其中男13例,女2例;右侧11例,左侧4例;年龄11~23岁,平均年龄16岁;合并明确肘关节脱位7例,合并尺神经损伤症状1例. 受伤至手术时间3~6d. 对术后患者骨折愈合情况及肘关节功能情况进行随访. 结果 15例患者获得随访,随访时间13~24个月,平均15个月. 所有患者术后切口均一期愈合,无内固定失效、骨骺早闭、骨块缺血坏死,所有随访患者获得骨性愈合,平均愈合时间12周,根据Mayo肘关节功能评分( MEPS) ,肘关节功能优14例,良1例. 结论 空心螺钉治疗肱骨内上髁骨折可以早期进行功能锻炼,肘关节功能恢复好,临床疗效满意.
