This study describes the development and validation of a protocol for MRI assessment of the distal radial and ulnar periphyseal area in gymnasts and non-gymnasts. Three musculoskeletal radiologists established a checklist of 27 (peri)physeal abnormalities based on literature and clinical experience and five other musculoskeletal radiologists and residents evaluated 30 MRI scans of the wrists of young gymnasts and non-gymnasts using this checklist. The authors determined reliability using the intraclass correlation coefficient (ICC) and Fleiss’ kappa and found good-to-excellent inter-rater and intra-rater agreement (respective ICCs 0.60–0.91 and 0.60–0.78) for seven characteristics and fair-to-excellent agreement...
