Evaluation of deltoid muscle quality in reverse shoulder arthroplasty: correlation of MRI findings with postoperative function and strength
Question RTSA success is measured by functional outcomes, but the relationship between postoperative imaging findings and functional results remains unclear. Findings Lower CSA and increased FI of deltoid, particularly anterior, were associated with reduced function and strength after RTSA. Clinical relevance Metal artifact-reduced MRI can assess postoperative deltoid FI and CSA, providing objective imaging biomarkers that complement clinical functional testing in the evaluation of patients following RTSA.
