Ideal management of the glenoid in anatomic shoulder arthroplasty remains controversial. Glenoid component loosening remains a common source of clinical concern and, in young, active patients, implantation of a glenoid prosthesis is often avoided. Efforts to decrease glenoid loosening have resulted in changes to prosthetic design and implantation techniques. Currently, a wide variety of glenoid component options are available, including metal-backed or all-polyethylene, bone ingrowth or ongrowth, inset, and augmented designs. Additionally, several alternatives are available for the young, active patient, including hemiarthroplasty, nonprosthetic resurfacing, and tissue interposition. Many recent clinical and biomechanical studies have examined these implant options. A thorough knowledge of glenoid anatomy, pathology, implant options, indications, and principles of implantation is necessary to optimize the outcome following anatomic shoulder arthroplasty.
在解剖型全肩关节置换术中，肩胛盂的理想处理方式仍存在争议。肩胛盂假体松动仍是临床常见的关注点，对于年轻、活动量大的患者，通常避免植入肩胛盂假体。为减少肩胛盂松动所做的努力导致了假体设计和植入技术的改变。目前，有多种肩胛盂假体可供选择，包括金属背衬或全聚乙烯、骨长入或骨附着、内嵌和增强型设计。此外，对于年轻、活动量大的患者还有几种替代方案，包括半关节置换、非假体表面置换和组织植入。最近许多临床和生物力学研究都对这些植入选项进行了考察。要优化解剖型全肩关节置换术后的效果，必须全面了解肩胛盂的解剖结构、病理、植入选项、适应证和植入原则。
