ASES (patient), median (IQRc) (n)
VAS pain (0–10)	0.5 (0, 3)	2.4 (0, 7.3)	0.5244	0 (0, 0)
Function subscore	43.3 (33.3, 48.3)	48.3 (15, 50)	0.5114	37.5 (33.3, 41.7)
ASES total score	89.2 (72.2, 98.3)	96.7 (30, 98.3)	0.9637	87.5 (83.3, 91.7)
VR-12, median (IQRc) (n)

Mental component score	55.1 (43.4, 61)	54.6 (38.8, 58.2)	0.5679	49.1 (46.2, 52.1)
SANE score, median (IQRc) (n)	85 (70, 95)	75.1 (35, 97.1)	0.7699	85.2

ASES = American Shoulder and Elbow Score, LTO = lesser tuberosity osteotomy, SANE = Single Assessment Numeric Evaluation, ROM = range of motion, VR-12 = Veteran Rand

^aStatistical tests performed on healed vs. nonunion nondisplaced groups. Displaced group were included in the table for descriptive purposes. Chi-square or Fisher exact tests were used for categorical data and Wilcoxon rank-sum tests were used for continuous non-normally distributed data to determine statistical significance between groups at an alpha level of 0.05.

^cThe IQR within parentheses is also the range for the displaced LTO group because of the low sample sizes of completed PROs.

^bThe first surgery occurrence was used for the patient specific data and associated comparative analyses.
