Case: A 41-year-old woman presented 5 years after glenohumeral arthrodesis. She experienced symptomatic relief following conversion to reverse total shoulder arthroplasty, regaining nearly full passive range of motion and >50% of normal active forward flexion, abduction, internal rotation, and external rotation.
Conclusion: Conversion from glenohumeral arthrodesis to reverse total shoulder arthroplasty in a patient with a functioning deltoid and adequate bone stock may provide symptomatic relief and improved function in the setting of symptomatic glenohumeral arthrodesis refractory to conservative measures.
