Background:
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.

Methods:
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.

Results:
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.

Conclusion:
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.

Is Morton’s neuroma in a pes planus or pes cavus foot lead to
differences in pressure distribution and gait parameters?

Morton’s neuroma (MN) is a compressive neuropathy of the common digital plantar nerve
causing forefoot pain. Foot posture and altered plantar pressure distribution have been identified
as predispoing factors, however no studies have compared individuls with different foot postures
with MN. Thus, we aimed to compare the effect of MN on spatiotemporal gait parameters and
foot-pressure distribution in individuals with pes planus and pes cavus. Thirty-eight patients with
unilateral MN were evaluated between June and August 2021. Nineteen patients with bilateral
pes planus and 19 age and gender-matched patients with pes cavus who had no prior surgery were
recruited. A Zebris FDM–THM–S treadmill system (Zebris Medical GmbH, Germany) was used to
evaluate step length, stride length, step width, step time, stride time, cadence, velocity, footpressure distribution, force and whole stance phase, loading response, mid stance, pre-swing
and swing phase percentages. There were no significant differences between the groups in
spatiotemporal gait parameters (p > 0.05). Patients with pes planus displayed the following results for step length (49.36 ± 8.38), step width (9.05 ± 2.12), stance phase percentage (65.92 ±
2.11), swing phase percentage (34.08 ± 2.12), gait speed (2.96 ± 0.55), and cadence (100.57 ±
8.84). In contrast, patients with pes cavus displayed the following results for step length (49.06 ±
8.37), step width (8.10 ± 2.46), stance phase percentage (64.96 ± 1.61), swing phase percentage
(34.79 ± 1.60), gait speed (2.95 ± 0.65), and cadence (99.73 ± 13.81). Foot-pressure distribution values showed no differences were detected in force, forefoot, and rearfoot pressure distribution, except for midfoot force (p < 0.05). The forefoot, midfoot, and rearfoot pressure values
for the pronated group were 32.14 ± 10.90, 13.80 ± 3.03, and 22.78 ± 5.10, and for the supinated group were 33.50 ± 11.49, 14.23 ± 3.11 and 24.93 ± 6.52. MN does not significantly
affect spatiotemporal gait parameters or foot-pressure distribution in patients with pes cavus or
pes planus.
