交通事故によるCRPS（complex regional pain syndrome）の判例検討

Precedents of CRPS (Complex Regional Pain Syndrome) Due to Traffic Accidents

　CRPS（complex regional pain syndrome）に関する交通事故の損害賠償判例18例を賠償科学的に分析した．後遺障害は重く（14級から5級），賠償額は高額なもの（平均1704万円）になっていたが，6例は心因的素因減額をされていた．診断までの期間は平均8カ月かかっており，6例は症状固定後に診断されていた．CRPSの診断を争点とした例は8例，うち3例は鑑定によってCRPS診断を否定されていた．CRPSは早期治療が重要な疾患なので，当初の診断はoverdiagnosisでもよいが，加害者側の理解を得て被害者の心因的要素によるCRPSの悪化を防ぐためには，骨シンチグラフィーや皮膚血流量などの客観的基準による診断を推奨する．

　Eighteen traffic accident trials concerning CRPS were analyzed. It is the problem that victims have severe after-effect with even small accidents. Six cases were diagnosed with CRPS after treatments had finished. Eight were at issue CRPS diagnosis in courts, and three of these were denied. Even though they were authorized grade 5-14^th with after-effect, six had compensatory damages deducted due to psychological factors. Early diagnosis and treatment are important, but accurate diagnosis under the criteria (especially objective one including bone scintigraphy and skin blood flow) should be done in order to make the assailants understand about CRPS. This could prevent victims from getting worse from psychological factors.
