脊椎手術の各種患者自己評価法の検討(第2報) : 頸椎疾患の分析  [in Japanese] Patients' Self Assessments of the Cervical Surgery : Short Term Results  [in Japanese]

目的:頸椎手術例に対して各種スケールで患者自己記入式評価を行い,より正確な術後成績の評価方法を追求することを目的に,結果を検討した.対象と方法:2005年7月〜2006年9月に頸椎手術を受けた114例を対象とした.Visual Analogue Scale (VAS), Neurological Cervical Spine Scale (NCSS), Neck Disability Questionnaire Index (NDI), Short-Form 36 (SF-36)を,術前,術後2週,3カ月,6カ月,12カ月の5回調査した.0ne-way ANOVAにて回答を解析し,Scheffe法で検定を行った.結果および結論:2005年7月〜2007年7月に528件の回答を得た.男性73例,女性32例,平均年齢58.6歳,平均経過観察期間17.1ヵ月であった.NCSSは調査期間中に有意差のある変化を観察できなかったが,VAS, NDI, SF-36のBodily Pain (BP), Mental Health (MH)では3ヵ月以後に有意差のある改善を認めた.

Object: The authors investigated patients' self assessments of cervical surgery and evaluated the short-term results. Materials and Methods: Our center had 114 cervical surgeries from July, 2005 to September, 2006 and we investigated all cases. Patients assessed Visual Analog Scale (VAS), Neurological Cervical Spine Scale (NCSS), Neck Disability Questionnaire Index (NDI) and Short-Form 36 (SF-36) v2 at admission, 2 weeks, 3 months, 6 months and 12 months of post operation. Data was analyzed by one-way ANOVA, and then differences among means were analyzed using the Scheffe method (p<0.05). Results: 105 patients (73 men and 32 women) responded to the scales at admission and returned 528 answers for 24 months. The mean age was 58.6 years (16〜86). The mean follow-up period was 17.1 months (range, 10〜24). We observed that VAS, NDI, SF-36-BP and MH improved significantly (p<0.01) from 3 to 6 months after the operations. NCSS, SF-36-PF, RP, SF, GH, VT and RE didn't improve significantly. Conclusions: VAS, NDI and SF-36-BP and MH had significantly improved from after 3 to 6 months with the cervical operations.
