Diagnosis and Management of Chronic Labral Tear with Secondary Adhesive Capsulitis
Clinical Presentation and Diagnosis
- The American College of Radiology suggests that clicking with circumduction is highly suggestive of labral pathology, as the torn labral fragment mechanically catches during shoulder rotation 1, 3
- A mechanism of direct impact from a significant fall creates sufficient force to cause labroligamentous injury, which is a common post-traumatic soft-tissue injury 1, 2, 4
- Labral tears frequently persist chronically if untreated, continuing to cause mechanical symptoms and pain years after the initial injury 3
- The American College of Radiology recommends obtaining standard shoulder radiographs to exclude fracture, dislocation, or significant osteoarthritis 4
- Radiographs can also identify bony Bankart lesions or Hill-Sachs deformities from the original trauma 3
Diagnostic Imaging
- The American College of Radiology states that MR arthrography is the gold standard for diagnosing labral tears and is superior to noncontrast MRI for detecting labroligamentous injuries 1, 2, 4
- In chronic cases, MR arthrography is preferred over noncontrast MRI because there will be no acute joint effusion to outline the labral tear 1, 2
Physical Examination and Pitfalls
- The American College of Radiology suggests performing O'Brien's test or crank test to provoke labral symptoms and clicking 3
- Assessing for painful arc and impingement signs can help evaluate for concurrent rotator cuff pathology 1, 3
- It is critical not to assume that chronicity means the condition is stable or benign, as chronic labral tears can cause progressive cartilage damage and secondary osteoarthritis 3
- The American College of Radiology advises against ordering noncontrast MRI as the initial advanced imaging in chronic cases, as MR arthrography provides superior visualization of labral pathology 1, 2, 4
