摘要: PURPOSE: To study the magnetic resonance (MR) imaging appearance of ulnar collateral ligament (UCL) and its insertion into medial epicondyle. MATERIALS AND METHODS: Sixteen normal 20 symptomatic elbows were examined with a 1.5-T unit. Normal imaged axial T2*-weighted three-dimensional Fourier transform sequences. Symptomatic coronal T1-, T2-, and/or short-inversion-time inversion-recovery RESULTS: In immature elbows, periosteum was seen as an extension UCL, enthesis had signal intensity characteristics that differed from those mature ligament. before epiphyseal fusion, segmentation subchondral bone resorption ossification center or without capsular tear. After full-thickness partial UCL tear at site insertion, subcortical resorption, seen. CONCLUSION: The MR char...
