Abstract

<p>初発前思春期投球肘内側障害例の高分解能MRIを調査した．対象は，発症から4週間以内にMRI撮像できた15例である．単純X線で異常を認めたのは15例中9例のみであったが，MRIでは全例異常所見を呈していた．骨化核の異常が12例，軟骨膜の偏位が12例うち途絶は9例，尺側側副靱帯（UCL）またはその周囲組織損傷は14例，鉤状結節の異常は7例であった．前思春期の投球肘内側障害は，骨化核に形態学的な異常を認めずとも，骨化していない軟骨およびそれを取り巻く軟骨膜の異常と，UCLのたるみや信号上昇，そして周囲の軟部組織損傷が主体であり，その初発例は急性損傷の可能性が示唆された．</p>
