Lésions du labrum acétabulaire

Abstract

The acetabular labrum is an important intraarticular structure of the hip. In terms of pathology, a significant risk exists in two situations: during traumatic dislocation of the hip (its interposition during the setting should be detected and treated), and in patients with insufficient acetabular covering (basal disinsertion in a hypertrophic labrum may be treated provided bone covering is undertaken in combination). Apart from these cases, idiopathic labral tears may be related with microtraumatic injuries, and be a part of femoroacetabular impingement. Some unclear joint abnormalities may be associated. Tomodensitometry and MRI can allow the visualisation of the labral tear. Hip arthroscopy is a well recognised technique that has a diagnostic role in this disease and that allows the resection of labral tears. These labral lesions are rarely isolated, and their prognosis is closely related to the associated cartilage lesions.
