indication of fasciotomy四肢の激しい腫脹を呈する外傷や下肢動脈塞栓解除術後の患者が異常な四肢の痛みや痺れを訴えたときは，筋区画症候群を疑い筋区画内圧測定をおこなう。内圧測定は，測定したい筋区画の筋内に針を刺し，圧トランスデューサに接続する。筋区画内圧が30mmHgを超える症例では筋区画症候群を合併する危険性が高く，筋膜切開を考慮する。筋区画内圧が40mmHg以上，拡張期血圧との差が20mmHg以下のときには積極的に筋膜切開をおこなう。 orthopedicsemergency medicine国試過去3年 Sep 22, 2020, 2:00 AM HirotoShishido

Initial test
May be normal in early stages
More advanced lesions appear as a subchondral bony fragment surrounded by radiolucency.
