Objective
Assess whether calcified labra cause an apparent radiographic joint space narrowing and evaluate outcomes following acetabuloplasty and labral reconstruction.
Key Findings
Calcified labral tissue can mimic joint space narrowing on radiographs without corresponding cartilage damage.
Arthroscopic acetabuloplasty combined with labral reconstruction resolves this radiographic illusion.
Patients experienced significant improvements in pain and hip function with no major cartilage deterioration.
Conclusion
Surgical treatment effectively addresses the misleading radiographic appearance caused by calcified labra, leading to improved clinical outcomes.
What Does This Mean for Providers?
Recognize calcified labrum as a potential source of apparent joint space narrowing to avoid misdiagnosing osteoarthritis.
Consider arthroscopic acetabuloplasty and labral reconstruction to restore function and relieve symptoms in these patients.
Use this understanding to guide diagnostic imaging interpretation and surgical planning to optimize patient outcomes.
