Do effects of humeral component retroversion on functional outcomes in reverse total shoulder arthroplasty for cuff tear arthropathy?
Range of motion after RTSA did not significantly differ between 20° and 0° humeral component retroversion angle. Most daily movements did not differ between the 2 groups, but patients in the 0° retroversion angle group scored better on activities related to internal rotation.
These results suggest that concurrent transient activation of the Wnt/β-catenin pathway could prevent radiation-induced salivary gland dysfunction.
