Abstract

OBJECTIVE

The aim of this study was to compare the microarchitecture of the greater tuberosity with or without rotator cuff tear and to obtain optimum location for anchor screw insertion for rotator cuff repair.

METHODS

Twenty-five humeral heads were harvested from 13 male cadavers of mean age 58.4 years, including 6 humeri with rotator cuff tear and 19 intact humeri. Six regions of interest (proximal, intermediate, and distal zones of the superficial and deep regions) were divided into the anterior (G1), middle (G2), and posterior (G3) areas of the greater tuberosity. Trabecular bone volume and cortical thickness were evaluated.

RESULTS

Total trabecular bone volume was greater in subjects <50 years old than in subjects >50 years old but did not differ significantly in subjects with and without rotator cuff tear. Cortical thickness in both intact and torn rotator cuff groups was significantly greater in the proximal and intermediate zones than in the distal zone. Cortical thickness was related to anatomic location rather than age or cuff tear.

CONCLUSION

The optimal location for anchor screw insertion during rotator cuff repair is either the proximal or intermediate region of the greater tuberosity. Age has more influence in terms of trabecular bone volume loss than rotator cuff integrity.

摘要

目的

本研究旨在比较存在或不存在肩袖撕裂时大结节的微观结构，并确定肩袖修复时锚钉置入的最佳位置。

方法

从13具平均年龄58.4岁的男性尸体上获取25个肱骨头，其中包括6个存在肩袖撕裂的肱骨和19个完整的肱骨。将六个感兴趣区域（浅层和深层的近端、中间和远端区域）划分为大结节的前侧（G1）、中间（G2）和后侧（G3）区域。评估小梁骨体积和皮质厚度。

结果

<50岁受试者的总小梁骨体积大于>50岁受试者，但存在和不存在肩袖撕裂的受试者之间无显著差异。完整和撕裂肩袖组的近端和中间区域的皮质厚度均显著大于远端区域。皮质厚度与解剖位置有关，而非年龄或肩袖撕裂情况。

结论

肩袖修复时锚钉置入的最佳位置是大结节的近端或中间区域。年龄对小梁骨体积丢失的影响比肩袖完整性更大。
