Effect of the critical shoulder angle on severe cranialization following total shoulder arthroplasty
Purpose - This study assesses the relationship of CSA, cranialization and radiographic glenoid loosening following TSA in the long-term follow-up. - Methods - 26 shoulders with TSA were examined radiographically postoperatively and after a mean 12.6 years. Severe cranialization was defined as direct...

| Summary: | Purpose - This study assesses the relationship of CSA, cranialization and radiographic glenoid loosening following TSA in the long-term follow-up. - Methods - 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. - Results - 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). - Conclusion - 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. |
