Acetabular labrum tears. Diagnosis and treatment.

An acetabular labrum tear was diagnosed and treated in 56 hips in 55 patients. Mechanical hip pain after a relatively minor injury with an associated click characterized the history. The tear of the labrum was shown with arthrography in 88% of the patients. Overall, 89% of the patients were improved by the diagnosis and treatment of an acetabular labrum tear: all 7 patients treated nonsurgically and 42 of 46 patients treated surgically. In recent years, it has been possible to arthroscopically confirm the diagnosis and treat some of these patients.
