This study assesses the relationship of CSA, cranialization and radiographic glenoid loosening following TSA in the long-term follow-up.
26 shoulders with TSA were examined radiographically postoperatively and after a mean 12.6 years. Severe cranialization was defined as direct humeral contact with the acromion and/or acetabularization of the acromion.
A CSA ≥35° was associated with severe cranialization. Glenoid loosening was present in 6/24 shoulders (25%). Severe cranialization was associated with glenoid loosening (p = 0.003).
A postoperative CSA ≥ 35° was associated with severe humeral cranialization after TSA in the long-term follow-up. Severe cranialization correlated with glenoid loosening.Level of evidence IV - retrospective cohort study.
本研究在长期随访中评估全肩关节置换术(TSA)后肱骨头颈干角(CSA)、颅化及影像学上的关节盂松动之间的关系。
对26例接受TSA的肩关节进行术后及平均12.6年后的影像学检查。严重颅化定义为肱骨头与肩峰直接接触和/或肩峰髋臼化。
CSA≥35°与严重颅化相关。24例肩关节中有6例(25%)出现关节盂松动。严重颅化与关节盂松动相关(p = 0.003)。
在长期随访中,TSA术后CSA≥35°与严重的肱骨头颅化相关。严重颅化与关节盂松动相关。证据等级IV - 回顾性队列研究。
