頚髄症における術前の頚部愁訴―前向き研究

Preoperative Neck Symptoms of the Compressive Cervical Myelopathy Patients. : Prospective Study

　圧迫性頚髄症に対し手術を施行した59名の，術前の頚部愁訴をNeck Pain and Disability Scaleを参考にして，前向きに調査した．術前から何らかの頚部愁訴を有する症例が80％に認められ，その頚部愁訴の程度は，正常人と比較すると明らかに高度であった．しかし，圧迫性頚髄症における術前の頚部愁訴の程度は，JOAスコアといった従来の頚髄症の重症度の評価法とは有意な相関関係を見出せなかった．圧迫性頚髄症の症例では，術前より何らかの頚部愁訴が存在することが多く，その評価方法にはJOAスコアとは異なった，独立した評価方法が必要である．

　We assessed the preoperative neck symptoms of 59 patients with compressive cervical myelopathy by means of a modified version of the Neck Pain and Disability Scale. The results showed that 80％ of the 59 patients had some neck symptoms before the operation. Neck symptoms of the preoperative cervical myelopathy patients were significantly more severe compared with those of the healthy persons. However, the preoperative neck symptoms of the cervical myelopathy patients were not significantly correlated with their JOA scores. Many cervical myelopathy patients have some neck symptoms, and an independent method, not the JOA score, needs to be used to evaluate their neck symptoms.
