Retrospective study with independent evaluation of patient outcomes approximately 1 year post-intradiscal electrothermal therapy (IDET). OBJECTIVE.: To assess functional status, symptoms, and subsequent treatments of patients treated with IDET.
IDET was introduced as a procedure for discogenic pain. Several studies reported improvement in >70% of patients.
Seventeen physicians referred 60 patients. Each patient had a positive discogram and had been treated with IDET. Patients were contacted approximately 1 year post-IDET, answered a telephone interview, and completed a self-administered questionnaire. Overall patient satisfaction, pain, functional and work status, analgesic usage, and subsequent treatments were noted. Kaplan-Meier survival curve was generated to predict the percentage that would undergo lumbar surgery after IDET.
Average age was 40 years (range 25-64 years) with 66% males and 34% females. Of the 44 patients who responded, 6 patients had a lumbar surgery within 1 year. Their outcomes were excluded from descriptive analysis; 97% continued to have back pain, 11 (29%) reported more pain post versus pre-IDET, 15 (39%) had less pain, and 11 (29%) reported no change; 11 (29%) reported using more pain medication post-IDET, 10 (26%) used the same, 12 (32%) used less, and 5 (13%) used none; 19 (50%) were dissatisfied with IDET, 14 (37%) were satisfied, and 5 (13%) were undecided; 20 (53%) would have the procedure again, 12 (31%) would not, and 6 (16%) were unsure. Most patients wore a brace >6 hours/day after surgery (duration 1-15 months). Sixteen (42%) were employed full-time pre-IDET and 11 (29%) were employed full-time post-IDET.
At 1-year post-IDET, half of patients were dissatisfied with their outcome. The percentage of patients on disability remained constant. The estimated proportion of patients undergoing fusion was predicted to be 15% at 1 year and 30% at 2 years.
对接受椎间盘内电热疗法（IDET）后约1年的患者结局进行独立评估的回顾性研究。
评估接受IDET治疗的患者的功能状态、症状及后续治疗情况。
IDET作为一种治疗椎间盘源性疼痛的方法被引入。多项研究报告称超过70%的患者病情有所改善。
17名医生转诊了60例患者。每名患者椎间盘造影呈阳性且接受过IDET治疗。在IDET治疗后约1年与患者取得联系，进行电话访谈并让其完成一份自填式问卷。记录患者的总体满意度、疼痛情况、功能及工作状态、止痛药物使用情况以及后续治疗情况。绘制Kaplan-Meier生存曲线以预测IDET治疗后接受腰椎手术的患者百分比。
患者平均年龄40岁（范围25 - 64岁），男性占66%，女性占34%。在44名有回应的患者中，6例在1年内接受了腰椎手术。他们的结局被排除在描述性分析之外；97%的患者仍有背痛，11例（29%）报告IDET治疗后疼痛较治疗前加重，15例（39%）疼痛减轻，11例（29%）报告无变化；11例（29%）报告IDET治疗后使用了更多止痛药物，10例（26%）用量相同，12例（32%）用量减少，5例（13%）未使用；19例（50%）对IDET治疗不满意，14例（37%）满意，5例（13%）未决定；20例（53%）愿意再次接受该治疗，12例（31%）不愿意，6例（16%）不确定。大多数患者术后每天佩戴支具超过6小时（持续时间1 - 15个月）。IDET治疗前16例（42%）为全职工作，IDET治疗后11例（29%）为全职工作。
IDET治疗后1年，一半的患者对其治疗结果不满意。残疾患者的比例保持不变。预计1年后接受融合手术的患者比例为15%，2年后为30%。
