Gender Correlation to the Prevalence of Pedal Neuromas in Various Interspaces - A Retrospective Study

Area of Science:

• Podiatric Medicine
• Radiology
• Orthopedic Surgery

Background:

• Morton's neuroma is a common digital nerve abnormality.
• Historically, it was thought to be more prevalent in women and in the third interspace.
• This study challenges traditional views by examining gender-specific variations in neuroma location.

Purpose of the Study:

• To evaluate the interspace location of Morton's neuromas.
• To determine if Morton's neuroma location varies between males and females.
• To investigate gender-specific differences in associated factors like plantar plate tears.

Main Methods:

• Retrospective analysis of 379 MRI reports for Morton's neuroma (ICD Code 355.6).
• Data collected included gender, age, laterality, trauma history, and interspace location (focus on 2nd and 3rd).
• Statistical analysis using Pearson Chi-Square and Mann-Whitney U tests (p<0.05).

Main Results:

• No significant gender-based differences in Morton's neuroma location (2nd vs. 3rd interspace).
• Age, laterality, and history of trauma did not significantly vary between genders.
• A statistically significant higher rate of plantar plate tears was observed in males (p=0.01).

Conclusions:

• Morton's neuroma location, laterality, and age distribution are similar in males and females.
• The higher prevalence of plantar plate tears in males warrants further investigation.
• Findings suggest a need to reconsider traditional assumptions about Morton's neuroma demographics.
