• » Rotator cuff imbalance, soft-tissue and capsular repair defects, and improper component sizing, positioning, and orientation can result in a high-stress environment at the periphery of the glenoid component-bone interface.
• » The optimal position and orientation of the glenoid for a given individual is currently unknown.
• » There have been advancements in glenoid design, with the advent of contemporary metal-backed and hybrid components, but their long-term efficacy has not been proven. Inset glenoid components have shown promising short- and mid-term results.
• » The augmented glenoid, which has shown satisfactory short-term results in the setting of posterior glenoid loss, is a potential option for glenoid bone loss that is too severe for eccentric reaming. It may be technically easier than bone-grafting, does not require union, and is not at risk of collapse or bone graft resorption.
• » Advances in surgical technique, including patient-specific instrumentation, may provide additional accuracy, especially in dysplastic and eccentrically worn glenoids; however, evidence for clinical benefit is still lacking.

解剖型全肩关节置换术中Glenoid设计的进展

• »肩袖的不平衡，软组织和囊的修复缺陷以及不正确的部件尺寸，位置和方向会导致关节盂部件-骨界面周围的高应力环境。
• »目前尚不清楚给定个体的关节盂最佳位置和方向。
• »随着现代金属背衬和混合组件的出现，关节盂设计有所进步，但长期效果尚未得到证实。插图关节盂部件显示出令人鼓舞的短期和中期结果。
• »增强型关节盂在短期后关节盂丢失的治疗中已显示出令人满意的短期结果，它是关节盂骨丢失的一种潜在选择，对于偏心扩孔而言，这太严重了。从技术上讲，它可能比植骨更容易，不需要联合，并且没有塌陷或植骨吸收的风险。
• »外科手术技术的进步，包括针对特定患者的仪器，可能会提供更高的准确性，尤其是在发育异常和偏心磨损的关节盂上；但是，仍然缺乏临床获益的证据。
