Comparison of Patient Demographics by Imaging Study Use

	Mean Age, y (P Value)	Mean CCI (P Value)	Patient Sex, % Male (P Value)
Anterior shoulder stability surgery
XR only	37.2 (P = .01)	0.65 (P = .66)	66.6% (P < .001)
MRI only (with or without XR)	35.5 (P = .01)	0.63 (P = .55)	67.7% (P < .001)
CT only (with or without XR)	38.6 (P < .001)	0.93 (P < .001)	69.5% (P < .001)
CT and MRI (with or without XR)	33.5 (P < .001)	0.74 (P = .001)	80.0% (P = .reference)
Posterior shoulder stability surgery
XR only	44.2 (P = .34)	0.88 (P = .05)	67.6% (P = .90)
MRI only (with or without XR)	39.3 (P < .001)	0.82 (P = .74)	64.5% (P = .53)
CT only (with or without XR)	45.8 (P = .17)	0.91 (P = .66)	75.5% (P = .22)
CT and MRI (with or without XR)	40.1 (P = .02)	1.11 (P = .004)	68.2% (P = reference)

NOTE. This table demonstrates differences in patient age, sex, and between patients who obtained different preoperative imaging workups before anterior or posterior shoulder stabilization surgery.

CCI, Charlson Comorbidity Index; CT, computed tomography; MRI, magnetic resonance imaging; XR, plan radiograph.
