Relevance of Scapula Function and Preoperative Factor after Reverse Total Shoulder Arthroplasty

Abstract

Purpose: To confirm the relevance of preoperative factors based on post-reverse total shoulder arthroplasty (RTSA) scapula function using scapula-45 radiography.

Method: Twenty-eight patients were observed for more than 6 months after RTSA. We evaluated how the preoperative physical findings had an influence on their postoperative scapular index, which indicates postoperative scapula function.

Results: The only significant independent variable that could be extracted for the postoperative scapular index was the preoperative scapular index.

Conclusion: The only factor affecting the postoperative scapular index is the preoperative scapular index.
