Bone scintigraphy can identify acetabular labral tears, a common cause of hip pain. Specific uptake patterns in the acetabular rim are characteristic of these tears, aiding diagnosis.

Area of Science:

  • Orthopedics
  • Radiology
  • Sports Medicine

Background:

  • Acetabular labral tears are a significant cause of hip pain, particularly in young adults with hip dysplasia and older individuals with degenerative hip conditions.
  • Accurate diagnosis is crucial for effective management and treatment planning.

Purpose of the Study:

  • To evaluate the utility of bone scintigraphy in diagnosing acetabular labral tears.
  • To identify characteristic scintigraphic patterns associated with labral tears.

Main Methods:

  • Retrospective analysis of bone scintigraphy in 27 patients with confirmed acetabular labral tears (diagnosed via MRI/arthroscopy).
  • Comparison with bone scintigraphy findings in 30 patients without labral tears, investigated for other hip pain causes.

Main Results:

  • Patients with labral tears exhibited hyperemia and increased delayed uptake in the superior or superomedial acetabulum.
  • A distinct "eyebrow" pattern of uptake was observed in cases of superomedial tears.
  • These specific scintigraphic patterns were not present in patients without labral tears.

Conclusions:

  • Increased uptake in the superior or superomedial acetabular rim is a characteristic finding of acetabular labral tears.
  • The absence of this specific scintigraphic pattern holds a high negative predictive value for diagnosing labral tears.
