Purpose
To characterize clinical, radiographic, histologic, and arthroscopic features of amorphous calcifications in the acetabular labrum.
Methods
Retrospective review of 16 patients undergoing hip arthroscopy with labral calcifications; symptoms, imaging, and intraoperative findings analyzed.
Key Findings
- Mostly female patients, average age 37.
- All presented with anterior groin pain and labral tears associated with femoroacetabular impingement (FAI).
- Calcifications (~3.2 mm) distinct from os acetabuli, located in anterosuperior labrum.
Conclusion
Amorphous labral calcifications represent a distinct pathology strongly linked to FAI and labral tears.
What This Means for Patients
Groin pain patients with labral calcifications should be evaluated for FAI, which may contribute to symptoms treatable with surgery.
What Does This Mean for Providers?
- Consider amorphous calcifications as a marker for underlying FAI in patients with labral pathology.
- Imaging and arthroscopic evaluation should include assessment for calcifications when symptoms persist.
- Surgical planning may need to address calcifications alongside labral repair.
