What is considered the gold standard for identifying a labral tear?

The gold standard for identifying a labral tear is arthroscopic surgery of the shoulder. This is primarily because arthroscopy allows for direct visualization of the labrum, which provides conclusive evidence of any tears or associated pathology. During this minimally invasive procedure, the surgeon can assess the condition of the shoulder joint structures, thereby confirming the diagnosis and potentially addressing any issues found during the process.

While Magnetic Resonance Imaging (MRI) is a useful non-invasive tool that can suggest the presence of a labral tear, it may not always provide definitive results due to limitations such as the quality of imaging and the possibility of false positives or negatives. Ultrasound can offer real-time imaging but lacks the sensitivity and specificity of arthroscopy for assessing complex shoulder structures. X-ray imaging is primarily used for evaluating bone conditions and does not directly visualize soft tissue structures like the labrum. Therefore, when a definitive diagnosis is required, arthroscopy remains the most reliable method.
