S^3肱骨近端锁定钢板治疗肱骨近端骨折短期疗效分析

Initial outcome and efficacy of S^3 proximal humerus locking plate in the treatment of proximal humerus fractures

目的探讨S3肱骨近端锁定钢板治疗肱骨近端骨折的短期疗效。方法应用S3肱骨近端锁定钢板治疗肱骨近端骨折22例,按Neer分型,其中二部分骨折4例,三部分骨折11例,四部分骨折7例。结果随访时间3～15个月,平均6.2个月。术后肩关节功能参照Neer功能评分标准,优17例,良4例,可1例,优良率为95.5%。结论新型的S3肱骨近端锁定钢板独特的设计理念给肱骨近端骨折复位后提供了牢固的软骨下支撑和内固定支架,应用该钢板治疗肱骨近端骨折可获得较好的固定效果。

Objective To explore the initial outcome and efficacy of S3 proximal humerus locking plate in the treatment of proximal humerus fractures. Methods Twenty-two patients with proximal humerus fracture were treated with the S3 proximal humerus locking plate. Most of the fractures were complex, two-part （ n = 4）, three-part （ n = 11 ） and four-part （ n = 7 ） fractures according to the Neer classification of the proximal humerus fractures. Results All patients were followed up for 3 - 15 months. There were no complications related to the implant including loosening or breakage of the plate. Good and excellent results were documented in 17 patients and fair results in 4 patients according the Neer scores of shoulder. Conclusion New design concepts of S3 proximal humerus plate provide the subchondral support and the internal fixation support. With the addition of the proper exercise of the shoulder joint, the outcomes would be satisfied.
