Background: Morton's neuromas are abnormalities of the common digital nerve branch located between the lesser metatarsal heads. Historically, interdigital (Morton's) neuromas have been characterized as being most common in the third interspace and predominantly identified in females. The principal investigator observed Morton's neuromas commonly in both the 2nd and 3rd interspaces in both genders. To the best of our knowledge, no literature exists to evaluate Morton's neuroma location with a focus on each gender independently. The present study evaluates Morton's neuroma interspace location and if there is a variation between males and females.

Methods: In this retrospective study, 582 de-identified ProScan magnetic resonance imaging reports, with a diagnosis code for Morton's neuroma (ICD Code 355.6), were obtained from their centralized database. These reports were evaluated for patients scanned from January 2015-April 2016. Incomplete records and those where the radiologist findings were not consistent with Morton's neuroma were eliminated. For the remaining 379 patients, data was collected on several factors such as gender, laterality, history of trauma, plantar plate tear, age and interspace location. Special focus was given to second and third interspace Morton's neuromas. Data was then evaluated statistically utilizing the Pearson Chi-Square and Independent Samples Mann-Whitney U Test with statistical significance deemed p<0.05.

Results: No statistically significant distribution between gender and second and third interspace Morton's neuromas were noted. Additionally, right vs left foot, age and history of trauma did not vary between genders in a significant way. Lastly, there was a statistically significant difference between the presence of plantar plate tears between genders. Male patients with Morton's neuromas were found to have a higher rate of plantar plate tears (34/92, p=0.01).

Conclusion: Our study found that there was not a statistically significant difference between female and male and Morton's neuromas location, laterality or age.
