Cervical discogenic pain originates from degenerated intervertebral discs and is a common condition in the middle-aged population. Cervical discs may herniate and give compressions to cervical nerves, with pain and functional limitation of the arms. DiscoGel is a device that can be useful in the treatment of cervical disc herniation, with very short operating time and low radiation dose.
Between March 2018 and April 2019 we performed this procedure on 38 patients with non-fissurated cervical herniation using 0.3-0.4 mL of DiscoGel injected under fluoroscopic guidance. The most common discs affected were C5-C6, C6-C7 and C4-C5. Outcomes were evaluated with Visual Analogue Scale (VAS) and Neuropathic Pain Symptom Inventory (NPSI) scores at 3, 6 and 12 months follow-up. A magnetic resonance imaging (MRI) scan of the cervical spine was performed 3 months after the procedure.
Postoperative examinations showed: VAS 2.15 ± 1.34 and NPSI 2.29 ± 0.71.Postoperative MRI performed 3 months after the procedure showed a good improvement of cervical disc herniation or bulging or protrusion. The mean dose area product (DAP) was 2803 mGy/cm with a mean fluoroscopy time of 4 minutes 22 seconds. DiscoGel is a suitable approach for non-fissurated cervical disc herniations, especially in patients that are not suitable for open surgery, with excellent postoperative results, fast recovery and a low radiation dose.
颈椎间盘源性疼痛源于退变的椎间盘，是中年人群中的常见病症。颈椎间盘可能会突出并压迫颈椎神经，导致手臂疼痛和功能受限。DiscoGel 是一种可用于治疗颈椎间盘突出症的设备，其手术操作时间极短，辐射剂量低。
2018 年 3 月至 2019 年 4 月，我们使用 DiscoGel 对 38 例非破裂性颈椎间盘突出症患者进行了治疗，注射剂量为 0.3-0.4ml，在透视引导下进行。受影响最常见的椎间盘为 C5-C6、C6-C7 和 C4-C5。通过视觉模拟量表（VAS）和神经病理性疼痛症状量表（NPSI）评分在术后 3、6 和 12 个月时进行评估。术后 3 个月时对颈椎进行磁共振成像（MRI）扫描。
术后检查显示：VAS 为 2.15±1.34，NPSI 为 2.29±0.71。术后 3 个月进行的 MRI 显示颈椎间盘突出症或膨出或突出得到了良好的改善。平均剂量面积乘积（DAP）为 2803mGy/cm，平均透视时间为 4 分 22 秒。DiscoGel 适用于非破裂性颈椎间盘突出症，尤其是对于不适合开放手术的患者，具有良好的术后效果、快速恢复和低辐射剂量。
