Preoperative thoracic kyphosis influences clinical outcomes and joint range of motion after reverse shoulder arthroplasty: A retrospective study from the FP-UCBM shoulder study group
Retrospective trial examines how thoracic kyphosis impacts shoulder function after surgery, suggesting alignment matters.
Key Points
This research investigates how preoperative thoracic kyphosis impacts postoperative shoulder function in patients undergoing reverse shoulder arthroplasty.
Retrospective review of 110 patients who underwent reverse shoulder arthroplasty from 2020 to 2022.
Thoracic kyphosis was measured using the Cobb angle on chest radiographs and patients were grouped based on angle severity.
Clinical outcomes were assessed using various scores and range of motion measurements, with follow-up lasting at least 2 years.
Patients with Cobb angle ≥47° had significantly lower shoulder flexion (132.7° vs 149.4°, p=0.031) and abduction (122.9° vs 142.1°, p=0.035).
This group also displayed lower average constant scores (CS) (75.1 vs 83.3, p=0.048).
No significant differences were found in SANE or VAS pain scores among the groups.
