The purpose of this research was to see if there were any differences in peak pressure, contact time, pressure-time integrals, and geometric variables such as forefoot width, foot length, coefficient of spreading, and arch index between subjects with Morton's neuroma (MN) and control subjects.
Dynamic peak plantar pressure, contact time, pressure-time integral, and geometric data were extracted using the EMED-X platform in 52 subjects with MN and 31 control subjects. Differences in peak pressure, contact time, pressure-time integral, and geometric data between participants with and those without MN were determined using independent-samples t tests. There were no significant differences in age, weight, height, and body mass index between patients with MN and control subjects.
There were no significant differences in the peak pressures of all masked areas and pressure-time integrals under metatarsal 2 to 4 heads between patients with MN and control subjects. In addition, no significant differences were observed between patients with MN and control subjects in geometric measurements of forefoot length, width, coefficient of spreading, foot progression angle, and arch index.
No relationship was found in this study between peak pressure, contact time, and pressure-time integral under the metatarsal heads, forefoot width, foot length, coefficient of spreading, and foot progression angle in a symptomatic MN group compared with a control group. The need to perform osteotomies to treat MN not associated with other lesser metatarsal phalangeal joint pathologies is questionable.
Level III, Case-Control Study.
本研究的目的是观察 Morton 神经瘤（MN）患者与对照受试者在峰值压力、接触时间、压力-时间积分以及诸如前足宽度、足长、展开系数和足弓指数等几何变量方面是否存在差异。
使用 EMED-X 平台提取了 52 例 MN 患者和 31 例对照受试者的动态足底峰值压力、接触时间、压力-时间积分及几何数据。采用独立样本 t 检验确定有 MN 患者与无 MN 患者在峰值压力、接触时间、压力-时间积分和几何数据方面的差异。MN 患者与对照受试者在年龄、体重、身高和体重指数方面无显著差异。
MN 患者与对照受试者在所有隐蔽区域的峰值压力以及第 2 至 4 跖骨头下的压力-时间积分方面无显著差异。此外，MN 患者与对照受试者在前足长度、宽度、展开系数、足前进角和足弓指数的几何测量方面也未观察到显著差异。
与对照组相比，本研究未发现有症状的 MN 组在跖骨头下的峰值压力、接触时间和压力-时间积分、前足宽度、足长、展开系数和足前进角之间存在关联。对于治疗与其他较小跖趾关节病变无关的 MN 而进行截骨术的必要性值得怀疑。
III 级，病例对照研究。
