Abstract

【緒言】上腕骨小頭離断性骨軟骨炎（以下OCD）に対する治療は術前画像評価と術中のICRS分類によって決定するが，ICRS分類では骨軟骨片の組織強度は考慮にない．今回，CT西中分類と術中empty signを基に骨軟骨片の温存が可能と判断した1例について報告する．<BR> 【症例】15歳男児，左肘痛．半年前から左肘痛を認め，単純X線岩瀬分類で遊離期巣内型，CT西中分類でstage3aのため手術の方針とした．術中所見ではICRS分類OCDⅢだったが，empty signは陰性であった．骨軟骨片の温存が可能と判断し，吸収ピンで骨軟骨片を固定した．3週間の外固定を行い，術後3カ月から投球動作を開始した．部活内のトラブルで野球からは離れたが，術後1年9カ月で良好な骨癒合が得られた．<BR> 【考察】CT西中分類で軟骨下骨の連続性が残存し，術中のempty signが陰性であれば，組織の温存が可能と考えられる．
