摘要:


文题释义:

冈上肌腱:是冈上肌的肌腱部分,连接冈上窝与肱骨大结节上部。此次研究中,其宽度为(12.0±1.5) mm、厚度为(4.0±0.8) mm。肱骨外展时,应力非线性递增,0°-90°间峰值应力从33.6 MPa升至130.4 MPa。冈上肌腱在肩部运动中负责载荷传递,高应力下易损伤,与肩袖损伤关系密切,研究其应力变化有助于防治相关疾病。
盂肱关节:由肩胛骨关节盂和肱骨头构成,是肩关节关键部分,关节软骨厚约2.4 mm。研究显示,肱骨外展、前屈时,其应力随角度增加。外展时关节软骨应力刺激更明显,90°外展时峰值应力24.3 MPa,高于前屈的19.3 MPa。该应力变化与关节软骨退变相关,对临床防治盂肱关节疾病意义重大。

摘要
背景:肩关节是人体复杂且活动度大的关节,其正常运作对日常生活至关重要,但也易发生损伤,肩袖损伤、盂唇损伤和脱位等疾病较为常见。了解肩关节生物力学特性对预防和治疗相关疾病意义重大,而有限元分析为研究提供了有力工具。
目的:采用有限元法分析肱骨外展与前屈运动中冈上肌腱及盂肱关节的受力变化。
方法:构建肩关节三维有限元模型,在Mimics软件中提取肱骨与肩胛骨三维模型,于Geomagic软件处理并实体化。在SolidWorks软件装配、建立不同角度模型,构建冈上肌腱和关节软骨。于Ansys软件设置材料属性、接触关系等,观察并分析冈上肌腱和关节软骨应力变化。
结果与结论:①Ⅰ型肩峰形态在肱骨外展角≤90°时未诱发肩峰下撞击征;②冈上肌腱应力随肱骨外展角度呈非线性递增趋势;③盂肱关节软骨应力与外展/前屈角度呈显著正相关性;④外展状态下关节软骨应力负荷显著高于前屈状态(P < 0.01);⑤通过有限元分析首次揭示了Ⅰ型肩峰在0°-90°外展范围的生物力学安全性特征,量化了冈上肌腱及盂肱关节的应力-角度动态关系;但因模型简化和静态分析,结论需多模态体内实验验证,但研究结论仍可为相关病症干预策略奠定理论基础。

Abstract: BACKGROUND: The shoulder joint is a complex and highly mobile joint in the human body. Its normal operation is crucial for daily life, but it is also prone to injuries. Diseases such as rotator cuff injuries, labral injuries, and dislocations are relatively common. Understanding the biomechanical characteristics of the shoulder joint is of great significance for the prevention and treatment of related diseases. Finite element analysis provides a powerful tool for such research.
OBJECTIVE: To analyze the force changes of the supraspinatus tendon and glenohumeral joint during humeral abduction and flexion using finite element method.
METHODS: A three-dimensional finite element model of the shoulder joint was constructed. The three-dimensional models of the humerus and scapula were extracted in Mimics software. They were processed and solidified in Geomagic software. In SolidWorks software, the models were assembled and models at different angles were established, and the supraspinatus tendon and articular cartilage were constructed. In Ansys software, material properties and contact relationships were set, and the stress changes of the supraspinatus tendon and articular cartilage were observed and analyzed.
RESULTS AND CONCLUSION: (1) The type I acromion morphology did not induce subacromial impingement syndrome when the humeral abduction angle was ≤ 90°. (2) The stress of the supraspinatus tendon showed a non-linear increasing trend with the humeral abduction angle. (3) There was a significant positive correlation between the stress of the glenohumeral joint cartilage and the abduction/flexion angle. (4) The stress load of the articular cartilage in the abduction state was significantly higher than that in the flexion state (P < 0.01). (5) Through finite element analysis, this study for the first time revealed the biomechanical safety characteristics of the type I acromion within the abduction range of 0°-90°, and quantified the stress-angle dynamic relationship of the supraspinatus tendon and the glenohumeral joint. However, due to model simplification and static analysis, the conclusions need to be verified by multi-modal in vivo experiments. Nevertheless, this study has laid an important theoretical foundation for the intervention strategy of related diseases.
