MRI of normal shoulder intratendinous signal MRI of rotator cuff full-thickness tear. Magnetic resonance imaging and ultrasound [46] are comparable in efficacy and helpful in diagnosis, although both have a false positive rate of 15–20%. [47] MRI can reliably detect most full-thickness tears, although very small pinpoint tears may be missed.
Empty beer can test: a positive test indicates rotator cuff tear, specifically, supraspinatus muscle tear; Drop arm test: a positive test indicates a supraspinatus tear; External Rotation test: a positive test indicates an infraspinatus or teres minor tear; Lift-off test: a positive test indicates subscapularis pathology
On non-contrast MRI or CT arthrography imaging, lesions might be harder to find, but the more recent 3T MRI scanners might increase the pick-up rate in the absence of contrast. [4] The accepted gold standard for identifying or detecting the glenolabral articular disruption lesion is MR arthroscopy (MRA).
Anterior shoulder dislocation and/or repeated anterior shoulder subluxations. [2] Diagnostic method: X-ray and MRI. Differential diagnosis: Anterior labroligamentous periosteal sleeve avulsion, Rotator Cuff Tears, SLAP Lesion, Impingement, Perthes lesion, Glenolabral articular disruption, Humeral avulsion of the glenohumeral ligament.

Medical history (the patient tells the doctor about an injury). For shoulder problems the medical history includes the patient's age, dominant hand, if injury affects normal work/activities as well as details on the actual shoulder problem including acute versus chronic and the presence of shoulder catching, instability, locking, pain, paresthesias (burning sensation), stiffness, swelling, and ...
If conservative measures are unsuccessful, surgery can be trialed. Surgery to cut the adhesions (capsular release) may be indicated in prolonged and severe cases; the procedure is usually performed by arthroscopy. Surgical evaluation of other problems with the shoulder, e.g., subacromial bursitis or rotator cuff tear, may be needed.
Shoulder arthrography can be used to study tears of the rotator cuff, glenoid labrum and biceps. [2] The type of contrast injected into the joint depends on the subsequent imaging that is planned. For pneumoarthrography, gas is used, for CT or radiographs, a water-soluble radiopaque contrast, and for MRI, gadolinium. Double-contrast ...
Ultrasonography, arthrography and MRI can be used to detect rotator cuff muscle pathology. MRI is the best imaging test prior to arthroscopic surgery. [2] Due to lack of understanding of the pathoaetiology, and lack of diagnostic accuracy in the assessment process by many physicians, [19] several opinions are recommended before intervention.
