Background
Gluteus medius (GM) tears are a common cause of hip pain but can be difficult to diagnose. This study evaluates a new clinical test—resisted internal rotation—for its ability to detect GM tears.
Methods
The study compared 50 patients with GM tears to 50 patients without symptoms. Both groups underwent clinical exams, MRI, and arthroscopy. The resisted internal rotation test’s accuracy was compared to other clinical tests and imaging results.
Key Findings
The resisted internal rotation test was highly accurate in detecting GM tears, with 92% sensitivity and 85% specificity. It outperformed traditional clinical tests in detecting GM tears.
Conclusions
The resisted internal rotation test is a reliable and accurate method for diagnosing gluteus medius tears in patients with hip pain.
What Does This Mean for Patients
If you're experiencing hip pain, your doctor may use the resisted internal rotation test to better diagnose a gluteus medius tear, which could lead to more accurate treatment options.
