Abstract

Introduction

The acetabular labrum is a critical structure within the hip joint. Abnormality of the acetabular labrum is a significant cause of pain, and it plays an integral role in the development of osteoarthritis. This article reviews the normal anatomy and anatomical variants of the acetabular labrum and describes the technique for performing magnetic resonance arthrography. This article also reviews the diagnostic criteria and classification of tears of the acetabular labrum.

Conclusion

Magnetic resonance arthrography offers the best imaging of the acetabular labrum. The acetabular labrum has little anatomical variation. Irregularity of the labrum and fluid is associated with labral tear. Magnetic resonance arthrography is specific to the diagnosis of the acetabular labrum.
