Evaluation of Transverse Acetabular Ligament Assessment due to Acetabular Labral Tear in Patients Undergoing Magnetic Resonance Arthrography

Abstract

Objective:In this study, we investigated the relationship between labral tear with its stage and transverse acetabular ligament (TAL) morphology in patients who underwent magnetic resonance arthrography (MRA) examination for acetabular labral tear.Method:Radiological images of 55 patients who applied to our hospital with MRA for acetabular labral pathology were evaluated. Labral lesions were classified as post-traumatic (1A, 2A and 3A) and dysplastic (1B, 2B and 3B) according to the Czerny staging system. The widest contact surface and TAL area with the TAL femoral head were measured in MRAs of patients. In the statistical analysis, the widest contact surface of TAL with the femoral head and TAL area were compared to the right and left sides and according to the Czerny classification.Results:When labral pathologies were evaluated according to the Czerny classification, the widest contact surface of TAL with the femoral head and TAL area, left and right sides, and double groups (1-2,1-3,2-3) in Czerny 1-2-3 classification were compared as post-traumatic (1A, 2A and 3A) and dysplastic (1B, 2B and 3B) lesions of the labrum. As a result, no statistically significant difference was observed (p>0.05).Conclusion:There was no significant relationship between the staging of acetabular labral pathologies and TAL morphology, suggesting that TAL cannot be shown as a predisposing factor in terms of acetabular labral tear.
