Abstract

BACKGROUND

Morton's neuroma is a mechanically induced degenerative neuropathy.

METHODS

We compared clinical and MRI findings in 76 feet treated operatively for Morton's neuroma and 40 feet with different pathologies (controls).

RESULTS

In the 'treatment group' web space tenderness (WST) was positive in 95%, foot squeeze (SQU) in 88%, plantar percussion (PLP) in 61%, and toe tip sensation deficit (TTSD) in 67%. MRI identified neuromata in 97%. Histological examination confirmed neuroma excision in 99%. Frequency of positive tests was significantly higher in the treatment group compared to controls. MRI revealed (asymptomatic) neuromata in 10/40 (25%) feet in the control group. TTSD was similarly positive in asymptomatic and symptomatic neuromata. TTSD in association with any other test being positive, was significantly more frequent in symptomatic neuromata.

CONCLUSIONS

The diagnosis of Morton's neuroma, based on clinical and imaging findings, was accurate. Positive clinical testing was more frequent in the 'treatment' group compared to the 'control' group.

摘要

背景

Morton 神经瘤是一种机械性诱导的退行性神经病。

方法

我们比较了 76 例手术治疗的 Morton 神经瘤患者（治疗组）和 40 例不同病理患者（对照组）的临床和 MRI 表现。

结果

在“治疗组”中，95%存在跖间区压痛（WST），88%存在足挤压（SQU），61%存在足底叩击（PLP），67%存在趾端感觉缺失（TTSD）。MRI 发现神经瘤 97%。组织学检查证实神经瘤切除 99%。与对照组相比，治疗组的阳性检查频率显著更高。MRI 显示对照组中 10/40 只（25%）无症状神经瘤。无症状和有症状神经瘤的 TTSD 均为阳性。TTSD 与任何其他阳性检查联合，在有症状神经瘤中更为常见。
