BACKGROUND: A reduced @entity5529 ( @entity5529 ) is thought to be responsible for subcoracoid impingement. This only accounts for @entity179 . In traumatic tears, the subcoracoid space should be normal. HYPOTHESIS: The @entity5529 in @entity1 with @entity1796 is larger than that in @entity1 with degenerative tears and does not differ from @entity1 with an intact subscapularis tendon. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A total of 83 @entity1 with arthroscopically certified @entity924 were included in the study. Forty-four @entity1 had degenerative causes (group 1), and 39 had traumatic causes (group 2). The control group consisted of 20 @entity1 with @entity1796 and arthroscopically proven, intact subscapularis tendons (group 3). On preoperative axial magnetic resonance imaging, the distance between the @entity5529 was measured, and the values of the 3 groups were compared using the t test. RESULTS: The mean (  SD) @entity5529 in @entity1 with @entity179 was 8.6    2.0 mm (range, 4.0-13.2 mm) and was significantly (P = .0003) smaller than that in @entity1 with traumatic tears (10.2    2.0 mm; range, 6.6-16.2 mm) or controls (10.4    1.8 mm; range, 6.8-14.0 mm). The @entity5529 of controls and @entity1 with traumatic tears did not differ significantly (P = .7875). A @entity5529 of less than 6 mm only occurred in @entity1 with @entity179 . CONCLUSION: The hypothesis that the @entity5529 in @entity1 with @entity179 is significantly smaller than that in @entity1 with traumatic tears or intact subscapularis tendons was confirmed. The @entity5529 in @entity1 with traumatic tears does not differ from that in controls. A @entity5529 of less than 6 mm only occurs in @entity1 with @entity179 .
