The Bipolar Hip: Combined Acetabular and Femoral Pathomorphology Determine Hip Motion

Hip-femoral acetabular impingement.

Magnetic resonance imaging (MRI) has become a valuable technology for the diagnosis and treatment of femoroacetabular impingement (FAI). This article reviews the basic pathophysiology of FAI, as well as the techniques and indications for MRI and magnetic resonance arthrography. Normal MRI anatomy of the hip and pathologic MRI anatomy associated with FAI are also discussed. Several case examples...

Hip Anatomy in Femoral Acetabular Impingement

The acetabular cartilage complex is interposed between Figure 1: Hip Growth the ilium, ischium, and the pubis. This complex is composed of epiphyseal growth-plate cartilage adjacent to these bones and articular cartilage around the acetabular cavity. Interstitial growth of the triradiate cartilage leads to expansion and enlargement of the acetabulum (25). Development of the acetabulum and femor...

Arthroscopic management of hip pathomorphology.

The role for the arthroscopic correction of femoroacetabular impingement continues to evolve. As the understanding of hip pathomorphology improves and arthroscopic techniques for managing these disorders advance, the indications for arthroscopic femoroacetabular correction become clearer. Attention to detail with respect to diagnoses and surgical management is critical to optimize outcomes in t...

Hip-preserving surgery: understanding complex pathomorphology.

Introduction Recent evidence suggests that abnormal hip morphology may be the primary cause of osteoarthritis of the hip in young adults. Hip pathomorphology is manifested as acetabular deficiency or malorientation, or as femoral deformity or malorientation, and most commonly as a combination of these problems. Contemporary surgical intervention for hip preservation has been directed toward cor...
