中英文字幕：莫顿神经瘤（Morton's neuroma）

　　神经瘤是神经组织的良性增生，可见于人体的多个部分。莫顿神经瘤 (Morton's neuroma) 累及的是足部的神经，多见于第三与第四足趾间的神经。莫顿神经瘤可引起足底尖锐、灼热样疼痛。足趾也可能会出现刺痛、灼热痛，或是麻木的感觉。

Morton's Neuroma

莫顿神经瘤

Overview（概述）

This condition is a thickening of the nerve sheath that surrounds a nerve in the ball of the foot. It most commonly develops between the third and fourth toes. It also commonly occurs between the second and third toes.

　　莫顿氏神经瘤是足底球形区（脚球，足底部足趾与跖骨相连处呈球形）某条神经周围的神经鞘增厚的一种病变。通常发生于3、4趾之间，也常见于2、3趾之间。

Causes（原因）

Morton's neuroma develops as a response to irritation, pressure or injury to a plantar nerve. It is commonly linked to footwear - especially women's shoes - that put pressure on the toes and don't provide proper space for them. High-heeled shoes and shoes with narrow toe boxes are common culprits.

　　莫顿氏神经瘤是由于足底神经受刺激、受压或受伤的结果。常与鞋子有关，尤其是增加脚趾压力且无充足脚趾空间的女鞋。高跟鞋以及足趾部位狭窄的鞋子是常见的罪魁祸首。

Symptoms（症状）

Symptoms of Morton's neuroma include a sharp, burning pain in the ball of the foot that may radiate to the toes. The toes adjacent to the neuroma may sting or tingle, or they may feel numb. The condition may also cause the sensation of standing on a pebble beneath the ball of the foot.

　　莫顿氏神经瘤的症状包括脚球处尖锐的、烧灼样的疼痛并可放射到足趾。与神经瘤毗邻的足趾可有刺痛和麻木。本病还可产生脚球处踩在小石子上的感觉。

Treatment（治疗）

Treatment depends on the severity of the neuroma. Conservative treatment options include flat shoes with roomy toe boxes, and the use of inserts, pads or cushions. Corticosteroid injections may also provide pain relief. If these options are not successful, surgery may be needed to decompress the nerve or to remove the enlarged portion.

　　根据神经瘤的严重程度来决定治疗方案。保守治疗方案包括穿足趾部宽松的平底鞋，使用插片、板及垫子。局部激素注射可能会缓解疼痛。如果这些方法无效，可能需要手术对神经进行减压，去除增生的部分。
