Mechanisms of shoulder trauma: Current concepts

Figure 7 Computed tomography arthrography is useful in cases of false-negative magnetic resonance imaging results. A: Posterior labral tear on the sagittal view; B: Superior labral anterior posterior lesions are best detected on the coronal view; C: Computed tomography arthrogram is the modality of choice in cases of undetected subscapular tears. The sagittal view showed widening of the bicipital canal, which is an indirect sign of subscapularis rupture and delamination with penetration of contrast fluid into the tendon (orange arrow).
