Morton's neuroma is a common cause of metatarsalgia. This study evaluated the efficacy of ultrasound guided alcohol injection as a treatment for this condition.
Data from 87 treatment courses were included in this study with a mean follow of 14.3 months.
Technical success was 100%. One patient developed symptoms consistent with an allergic reaction to the injection and one patient declined further injection because of periprocedural pain. Partial or total treatment response was achieved in 66%, with 32% of patients having complete resolution of pain. The median visual analogue score (VAS) decreased from 8 pre-procedure to 4 post-procedure (p < 0.0001). Procedural success was greater in patients under 55 years old and in those with solitary neuromas. Seventeen patients (20%) went on to have surgery due to continuing pain.
Ultrasound guided alcohol ablation for the treatment of Morton's neuroma was a safe procedure that significantly reduced pain and may offer an alternative therapy to surgery.
Morton 神经瘤是导致跖痛症的常见原因。本研究评估了超声引导下酒精注射治疗这种疾病的疗效。
本研究纳入了 87 次治疗过程的数据，平均随访时间为 14.3 个月。
技术成功率为 100%。1 名患者出现与注射过敏反应相符的症状，1 名患者因围手术期疼痛而拒绝进一步注射。66%的患者获得部分或完全治疗反应，32%的患者疼痛完全缓解。中位数视觉模拟评分（VAS）从术前的 8 分降至术后的 4 分（p<0.0001）。55 岁以下患者和单发神经瘤患者的手术成功率更高。17 名患者（20%）因持续疼痛而继续接受手术。
超声引导下酒精消融治疗 Morton 神经瘤是一种安全的方法，可显著减轻疼痛，并可能为手术提供替代疗法。
