摘要:

背景:肱骨近端骨折最佳修复方法目前仍存争议。尽管不同的内固定方式被用于修复肱骨近端骨折,但是所有内固定方法均存在较高的术后并发症,如螺钉切割琥珀螺钉退出、骨不连及肩峰撞击征等。考虑到传统内固定的缺点,作者设计了一种新型肱骨近端翼式解剖钢板用于修复肱骨近端骨折。
目的:评估肱骨近端翼式解剖钢板置入内固定修复肱骨近端骨折的临床效果和并发症。
方法:回顾性分析2012年9月至2013年9月采用自制新型肱骨近端翼式解剖钢板置入内固定修复肱骨近端骨折患者60例,骨折根据Neer分型:二部分骨折24例,三部分骨折31例,四部分骨折5例。按Constant-Murley评分评定肩关节功能,采用目测类比评分评定患肩疼痛度。
结果与结论:60例患者内固定后获得12-24个月随访,均获得骨性愈合,骨折愈合时间12-20周,平均(15.3±2.7)周。末次随访时Constant-Murley评分为45-98分,平均(81.5±14.6)分。肩关节疼痛目测类比评分为0-7分,平均(0.9±0.9)分。60例患者中共有11例(18%)出现并发症,其中3例(5%)发生螺钉穿出肱骨头关节软骨骨面、1例(2%)出现螺钉轻度退出、5例(8%)发生肱骨头内翻成角畸形(其中2例合并有螺钉穿出软骨面)、2例(3%)发生肱骨头坏死、1例(2%)发生肩峰撞击征,1例(2%)发生切口浅表感染。未出现肱骨头坏死、内固定失败等并发症。提示自制新型肱骨近端翼式解剖钢板置入内固定修复肱骨近端骨折,可以取得满意的固定效果,能够有效降低内固定后肩峰撞击征的发生,有利于肩关节功能恢复,是值得推荐的一种内固定物。

Abstract:

BACKGROUND: The best repair method for proximal humeral fractures remains controversial at present. Although different techniques have been described for proximal humerus fractures, all these techniques have high postoperative complications, such as cut-out or back-out of the screws, nonunion, and subacromial impingement. Given the shortcomings of conventional plate fixation system, we had designed a new type of proximal humeral wing-shape anatomical plate for the repair of proximal humeral fractures.
OBJECTIVE: To evaluate clinical outcomes and complications of proximal humeral wing-shape anatomical plate fixation for proximal humerus fractures.
METHODS: A total of 60 patients with proximal humerus fractures who underwent proximal humeral wing-shape anatomical plate fixation from September 2012 to September 2013 were retrospectively analyzed. According to 
Neer classification system, 24, 31 and 5 patients had 2-part, 3-part, and 4-part fractures, respectively. Functional evaluation of the shoulder was done using Constant-Murley score and Visual Analogue Scale was utilized for assessing the degree of shoulder pain.
RESULTS AND CONCLUSION: All 60 patients were followed up for 12-24 months after fixation, and obtained bone healing. The healing time was 15.3±2.7 weeks (range 12-20 weeks). At the final follow-up, the Constant-Murley score was 81.5±14.6 (range 45-98). The mean Visual Analogue Scale score was 0.9 ± 0.9 points (range 0-7 points). During the follow-up, the overall rate of complications was 18% in 11 cases of 60 cases, including intraarticular screw penetration in 3 patients (5%), back-out of the screws in 1 patient (2%), varus malunion in 5 (8%) patients (containing 2 cases combined with screw penetration), humeral head necrosis in 2 patients (3%), subacromial impingement in 1 patient (2%) and superficial infection of incision in 1 patient (2%). No cases of avascular necrosis or hardware failure were noted. Above data suggested that self-made new-type proximal humeral wing-shape anatomical plate fixation for repairing proximal humerus fractures can obtain satisfactory outcomes, effectively reduce the incidence of postoperative subacromial impingement, is helpful to the recovery of shoulder function, and deserves to be further used.
