Radiographic evaluation of osteochondritis dissecans of the humeral capitellum: A systematic review

J Orthop. 2021 Sep 14:27:114-121. doi: 10.1016/j.jor.2021.09.005. eCollection 2021 Sep-Oct.


Background: The purpose of this study was to evaluate radiographic-based classification systems for osteochondritis dissecans (OCD) of the capitellum and determine their agreement with intraoperative findings.

Methods: Using PRISMA guidelines, we analyzed 44 studies utilizing a total of 19 classification systems.

Results: Magnetic resonance imaging (MRI)-based systems showed better predictive value of intraoperative staging, and the Itsubo and Kohyama classifications showed best predictive value for lesion stability.

Conclusions: No classification system effectively correlated with intraoperative findings. A combination of radiograph, MRI, and computed tomography will most accurately determine OCD lesion stability.

Level of evidence: IV, Systematic Review.
