✦ Synopsis
Objective:
The aim of this study was to investigate the relationship between abnormal acetabular labrum depicted by radial magnetic resonance and progressive joint space narrowing (jsn) of hip dysplasia.
Methods:
Subjects were 23 joints [21 patients; mean age: 35.1 years (16-53 years)] that had acetabular dysplasia with lateral center-edge angle of wiberg (ce angle) greater than 5 degrees and smaller than 25 degrees (mean, 16.4 degrees ), which did not show any arthrotic changes on plain radiograms and were followed up for 3 years or longer. radial images of acetabular labrum were classified into three stages.
Results:
Progression of jsn was not significantly related to ce angle but to progression of mri stage (p=.006). in multivariate analysis, one rank progression of mri stage was significantly associated with progression of jsn (adjusted or=11.41, 95% ci: 1.51-86.24, p=.018).
Conclusion:
Our findings showed that in patients whose acetabular dysplasia has 5-25 degrees ce angle, mri staging based on radial mri is a better factor for prediction of progression of jsn than ce angle.
