Fig. 4From: Analysis of in vivo humeral rotation of reverse total shoulder arthroplasty patients during shoulder abduction on the scapular plane with a loadThe rotation angle of the humeral component relative to scapular component. Internal ( +) / external (-) rotation. The significance level adjusted by Bonferroni correction was 0.00714. A significant difference (P < 0.05) was found at 40 degrees shoulder abductionBack to article page
