Since the advent of Neer's total shoulder arthroplasty in 1974, glenoid implant design has evolved to optimize patient function and increase implant longevity. Glenoid loosening continues to be a major cause of total shoulder arthroplasty failure due to both patient and implant factors. The more recent development of posterior augmented glenoids, peg fixation with ingrowth potential, inlay implants, zoned conformity implants, and convertible glenoids have all shown promising results in improving glenoid fixation and survival in different clinical circumstances. The increased utilization of 3D CT scans, preoperative planning, and patient-specific instrumentation has paralleled innovation in glenoid implants with the aim of improving the accuracy of glenoid implant placement to further optimize patient function and implant longevity. Specific indications for the variety of glenoid implants available today are still being studied. The shoulder arthroplasty surgeon should consider patient and implant factors and patient goals when determining the appropriate implant for each individual.
自1974年尼尔(Neer)全肩关节置换术问世以来,肩胛盂植入物的设计不断演变,以优化患者功能并延长植入物使用寿命。由于患者和植入物自身的因素,肩胛盂松动仍然是全肩关节置换术失败的主要原因。后增型肩胛盂、具有向内生长潜力的 peg 固定、嵌体植入物、分区顺应性植入物和可转换肩胛盂等较新的进展,在不同临床情况下改善肩胛盂固定和生存率方面均显示出了令人鼓舞的结果。三维CT扫描、术前规划和患者特异性器械的更多使用,与肩胛盂植入物的创新同步进行,目的是提高肩胛盂植入物放置的准确性,以进一步优化患者功能和植入物使用寿命。目前可用的各种肩胛盂植入物的具体适应症仍在研究中。肩关节置换外科医生在为每个患者确定合适的植入物时,应考虑患者、植入物因素以及患者的目标。
