The specific aims of this experiment were (1) to develop a clinically relevant model of anteroinferior shoulder dislocation in the apprehension position to compare the biomechanics of the intact anterior capsuloligamentous structures, and (2) to evaluate the initial strength of an open Bankart and of a coracoid abutment procedure. Fifteen shoulders from deceased donors were used. For the intact shoulders, mean peak load was 486 N, and stiffness was 26,7 N/mm. For the Bankart repair, the mean peak load was 264 N, and mean stiffness was 14.1 N/mm. Transosseous repairs failed by suture pullout through soft tissues. For the coracoid abutment repair, the mean peak load was 607 N and stiffness was 25.57 N/mm. This study reveals that the biomechanical performance of the Bankart and coracoid abutment repairs fails to reproduce the properties of the natural intact state.
（1）建立一个在恐惧位下临床上相关的肩前下脱位模型，以比较完整的前囊韧带结构的生物力学；（2）评估开放性Bankart修复术和喙突对接手术的初始强度。使用了15个来自已故捐赠者的肩部标本。对于完整的肩部，平均峰值负荷为486N，刚度为26.7N/mm。对于Bankart修复，平均峰值负荷为264N，平均刚度为14.1N/mm。经骨修复因缝线通过软组织拉出而失败。对于喙突对接修复，平均峰值负荷为607N，刚度为25.57N/mm。本研究表明，Bankart修复和喙突对接修复的生物力学性能未能重现自然完整状态的特性。
