[Intra-articular injury patterns as evidence of mechanical hip disorders].

Abstract

FAIS is a well-defined clinical entity with morphological alterations, whether constitutional or acquired, that can lead to damage of the labrum and acetabular cartilage following distinct injury patterns with subsequent osteoarthritis. The combination pathology of cam and pincer deformity is the most common variant. The characteristic changes of the chondrolabral complex that are caused by the dysplasia differ from these FAIS changes. Furthermore, femoral torsion also has an impact on the clinical appearance of Cam- or Pincer-FAIS.
