In recent years, an appreciation for the dynamic relationship between glenoid and humeral-sided bone loss and its importance to the pathomechanics of glenohumeral instability has substantially affected modern treatment algorithms. However, comparatively less attention has been paid to the influence of glenoid version on glenohumeral instability. Limited biomechanical data suggest that alterations in glenoid version may affect the forces necessary to destabilize the glenohumeral joint. However, this phenomenon has not been consistently corroborated by the results of clinical studies. Although increased glenoid retroversion may represent an independent risk factor for posterior glenohumeral instability, this relationship has not been reliably observed in the setting of anterior glenohumeral instability. Similarly, the effect of glenoid version on the failure rates of surgical stabilization procedures remains poorly understood.
近年来，人们对肩盂和肱骨头侧骨量丢失之间的动态关系及其对肩盂不稳定的病理力学的重要性有了更深入的了解，这极大地影响了现代治疗方案的制定。然而，人们对肩盂形态的影响关注较少。有限的生物力学数据表明，肩盂形态的改变可能会影响使肩盂关节不稳定所需的力。但是，临床研究的结果并没有一致证实这一现象。虽然肩盂后倾增加可能是肩盂后向不稳定的一个独立危险因素，但在肩盂前向不稳定的情况下，这种关系尚未得到可靠的观察。同样，肩盂形态对手术固定失败率的影响也知之甚少。
