目的： 探讨应用肩峰前外侧小切口治疗肱骨近端骨折的可行性、手术方法及疗效。方法： 选择2012年1月至2014年10月应用肩峰前外侧小切口入路治疗肱骨近端骨折患者32例，其中男19例、女13例，平均年龄46岁（22~78岁）。骨折原因：摔伤 21 例、车祸伤 11 例；按Neer分型：二部分骨折18例、三部分骨折12例、四部分骨折2例。复位骨折后，以肱骨近端解剖型锁定钢板固定，术后开始严格地被动练习肩关节功能。每月复查，待骨折愈合后开始持重练习。结果： 32例患者平均随访11个月（3~34个月），骨折全部愈合，无内固定物失效及钢板断裂，无伤口感染病例，肩关节ConstantMurley功能评分平均86分（69~100分）。结论： 应用肩峰前外侧小切口入路可以完成对肱骨近端骨折钢板内固定的手术治疗，但是对患者特点和骨折类型以及术者经验要求较高，临床实践中要注意适应征的选择，以达到良好的治疗效果。

Objective： To investigate the feasibility, surgical technique and effect of osteosynthesis for proximal humerus fractures through the minimal incision anterolateral acromion. Methods: In this study, 32 patients of proximal humeral fractures were selected and treated through the minimal incision anterolateral acromion between January 2012 and October 2014. Of these patients, there were 19 males and 13 females, with mean age 46 years old (range: 22-78 years). The mechanism of injury was a trauma of simple fall for 21 patients and motor vehicle accident for 11 patients. According to Neer classification, 18 cases had two-part fractures, 12 had three-part fractures, and 2 had four-part fractures. All patients were sustained operation of open reduction and internal fixation. The average delay between trauma and surgery was 4 d (0.5-10.0 d). The operations were performed in invariable operating room with general anesthesia. The fractures were reduced and immobilized with anatomical locking plate through the minimal  incision anterolateral acromion during operation. Patients were received passive motion after operation.  Results: All the 32 cases were followed up ranging from 3 to 34 months with an average of 11 months. All the fractures were healed. There was neither failure of internal fixation nor incision infection case. The functional results of the shoulder, according to Constant-Murley score was on an average 86 (range: 69-100). Conclusion: The treatment for proximal humeral fractures through the minimal incision anterola-teral acromion approach is a feasible and effective method, which shows good results for treating proximal humerus fractures with correct indication. There are several advantages compared with conventional deltopectoral   approach. They are minimal soft tissue disruption, minimal blood loss and easily to manipulate technique. But it required selection of indication strictly and surgeon’s experience.
