摘要:


文题释义:

PHILOS锁定钢板:是肱骨近端骨折最常用的固定方式。其特点是锁定螺钉的成角稳定性及肱骨头内多个角度螺钉的组合排列的结构能增加对肱骨头的把持,降低了内固定失效的风险,因此在临床广泛运用。
肱骨距螺钉:肱骨距是指肱骨头内下方解剖颈至外科颈弯曲处的致密骨板,它具有支撑肱骨头、防止其内翻塌陷的作用。临床上肱骨近端骨折常在此区域置入螺钉恢复肱骨内侧支撑,称为肱骨距螺钉。


背景:肱骨近端锁定内固定系统钢板是肱骨近端骨折最常用的固定方式,但临床上其失败率仍较高,螺钉的合理置入是影响内固定稳定性的重要因素。

目的:探讨在肱骨近端锁定内固定系统钢板治疗肱骨近端骨折中肱骨头螺钉的分布特点及对内固定失效的影响。
方法:对2017年1月至2021年12月在广州中医药大学第三附属医院收治的采用肱骨近端锁定内固定系统钢板内固定治疗的老年肱骨近端骨折患者进行回顾性分析,共纳入124例,其中男16例,女108例,年龄≥60岁,根据其术后是否出现内固定失效分为正常组(101例)和内固定失效组(23例)。收集患者年龄、性别、骨折类型、内侧柱完整性、钢板高度、颈干角、是否置入肱骨距螺钉、肱骨头螺钉数量,并根据术后数字X射线摄影正位片将肱骨头分为8个区,收集患者肱骨头螺钉在各区螺钉分布特点,绘制螺钉分布热力图。

结果与结论:①两组患者在年龄、性别、骨折类型、内侧柱完整性、钢板高度、颈干角、是否置入肱骨距螺钉、肱骨头螺钉数量方面均无统计学差异(P > 0.05);②但热力图显示,在正常组中肱骨头螺钉分布均匀,主要分散在4,6,7区;而内固定失效组的螺钉分布不均匀,主要集中在4,6区;此外,在肱骨距螺钉理想区域(7/8区)中,正常组螺钉明显多于内固定失效组;③提示在肱骨近端锁定内固定系统钢板治疗肱骨近端骨折过程中,肱骨头螺钉均匀分布是保证内固定效果的关键,合理的肱骨头螺钉分布有助于提高治疗效果和内固定成功率。

Abstract: BACKGROUND: Proximal humerus internal locking system locking plate is the most commonly used fixation method for proximal humeral fractures, but its failure rate is still high in clinical practice. Reasonable screw placement is an important factor affecting the stability of internal fixation.
OBJECTIVE: To investigate the distribution of humeral head screws in the treatment of proximal humeral fractures with proximal humerus internal locking system plate and its influence on internal fixation failure.
METHODS: From January 2017 to December 2021, data from patients with proximal humeral fractures undergoing proximal humerus internal locking system plate in Third Affiliated Hospital of Guangzhou University of Chinese Medicine were retrospectively analyzed. A total of 124 patients were enrolled, including 16 males and 108 females, at the age of ≥60 years. According to whether there was internal fixation failure after operation, they were divided into normal group (n=101) and internal fixation failure group (n=23). The patient’s age, gender, fracture type, the integrity of the medial column, plate height, neck-shaft angle, whether the talus screw was inserted, and the number of humeral head screws, were collected. The humeral head was divided into eight zones according to the postoperative digital radiography anteroposterior film, and the distribution characteristics of the screws in each zone were collected, and the heat map of the screw distribution was drawn.
RESULTS AND CONCLUSION: (1) There were no significant differences between the two groups in age, gender, fracture type, the integrity of the medial column, plate height, neck-shaft angle, whether to insert talus screws, and the number of humeral head screws (P > 0.05). (2) The heat map showed that the humeral head screws were evenly distributed in the normal group, mainly scattered in zones 4, 6, and 7. However, the screw distribution in the internal fixation failure group was not uniform, mainly concentrated in zones 4 and 6. In addition, in the ideal area of talus screws (7/8 zone), there were significantly more screws in the normal group than in the internal fixation failure group. (3) It is indicated that in the treatment of proximal humeral fractures with proximal humerus internal locking system plate, the uniform distribution of humeral head screws is the key to ensuring the internal fixation effect. A reasonable distribution of humeral head screws helps to improve the treatment effect and the success rate of internal fixation.  

Key words: proximal humerus fracture, proximal humerus internal locking system, locking plate, humeral head screw distribution, internal fixation failure
