Abstract：
BACKGROUND: Scoliosis behavior after curettage of spinal osteoid osteoma has been not clarified as most studies regarding scoliosis secondary to osteoid osteoma (OO) were case reports. The aims of this study were to investigate (1) clinical and radiographic features of scoliosis secondary to OO; (2) scoliosis behavior after Curettage of OO.
METHODS: A retrospective study was performed at patients who were diagnosed as OO clinically or pathologically from July 1998 to December 2019 in a single institution. Age, gender, location of pain, location of lesion and curve pattern of scoliosis were collected preoperatively. Intraoperative blood loss, operation time and surgical complications were documented. VAS scores and curve magnitude were collected pre- and postoperatively and at last follow-up.
RESULTS: The mean operation time was 124 ± 32 min and the average intraoperative blood loss was 274 ± 134 ml. The mean preoperative VAS score was 6.2 ± 2.7, and the mean postoperative VAS score was 2.1 ± 1.8. Thoracic scoliosis was improved from 22.7 ± 10.6° to 6.2 ± 4.3° after operation, and to 4.1 ± 4.3° at last follow-up. Lumbar scoliosis was improved from 18.1 ± 7.4° to 6.7 ± 5.2° after operation, and to 5.3 ± 3.9° at last follow-up. Trunk shift was improved from 34.7 ± 12.4 to 10.5 ± 7.2 mm after operation, and to 8.4 ± 5.6 mm at last follow-up. There was no significant differences as to sagittal radiographic parameters (P > 0.05).
CONCLUSIONS: Patients with spinal OO had a significantly high incidence of scoliosis. Patients could get rapid relief of pain and scoliosis with low occurrence. Night pain, pain at the concave side of curve, normal sagittal alignment could help differentiate it from scoliosis associated with lumbar disc herniation.

摘要：
背景：刮除脊柱骨样骨瘤后的脊柱侧凸行为尚未明确，因为大多数关于骨样骨瘤（OO）继发脊柱侧凸的研究都是病例报告。这项研究的目的是调查（1）OO继发脊柱侧凸的临床和影像学特征；（2）OO刮除后的脊柱侧凸行为。
方法：对1998年7月至2019年12月在单一机构中临床或病理诊断为OO的患者进行了回顾性研究。年龄,性别,疼痛的位置，术前收集病灶位置和脊柱侧凸曲线。术中失血,记录手术时间和手术并发症。术前、术后和末次随访时收集VAS评分和曲线大小。
结果：平均手术时间为124±32分钟，平均术中出血量为274±134ml。术前平均VAS评分为6.2±2.7，术后平均VAS评分为2.1±1.8。术后胸椎侧凸由22.7±10.6°改善为6.2±4.3°,末次随访至4.1±4.3°。术后腰椎侧凸由18.1±7.4°改善为6.7±5.2°,末次随访至5.3±3.9°。术后躯干移位从34.7±12.4提高到10.5±7.2mm，末次随访时达到8.4±5.6mm。矢状面X线参数差异无统计学意义(P>0.05)。
结论：脊柱OO患者脊柱侧凸的发生率明显较高。患者可以迅速缓解疼痛和脊柱侧弯，发生率低。夜痛，曲线凹侧疼痛，正常矢状位排列有助于将其与与腰椎间盘突出症相关的脊柱侧凸相鉴别。
