Area of Science:

  • Orthopedics
  • Radiology
  • Anatomy

Background:

  • The acetabular labrum is crucial for hip joint function.
  • Labral tears are a common cause of hip pain.
  • Labral pathology is implicated in osteoarthritis development.

Purpose of the Study:

  • To review the normal anatomy and MR appearance of the acetabular labrum.
  • To discuss imaging techniques for labral evaluation.
  • To cover clinical presentations of labral tears and associated conditions.

Main Methods:

  • Review of current literature on acetabular labrum anatomy and imaging.
  • Discussion of magnetic resonance (MR) imaging findings.
  • Synthesis of information on clinical presentations and associated pathologies.

Main Results:

  • Detailed description of normal acetabular labrum anatomy and MR characteristics.
  • Explanation of imaging modalities for labrum assessment.
  • Discussion of labral tear etiologies, including developmental dysplasia and femoroacetabular impingement.

Conclusions:

  • The acetabular labrum is vital for hip biomechanics and health.
  • Accurate imaging and understanding of associated conditions are key for diagnosing labral pathology.
  • Further research may clarify controversies such as the sublabral sulcus.
