“…Though this attempt to create more space for the MN by cutting the DTML is a very common technique, no publication has been found that measures this space and that connects it with MN. For this reason, our results may be reinforced amidst the great variety of surgical techniques which aim at freeing the DTML to create more space for the MN [ 30 , 31 , 32 , 33 , 34 , 35 , 36 ].…”

Morton’s neuroma (MN) is a common condition in clinical practice. The compressive etiology is the most accepted, in which compression occurs in the tunnel formed by the adjacent metatarsals, the deep transverse metatarsal ligament (DTML) and the plantar skin. Ultrasound (US) is a reliable method of study. The presence of insufficient space under the DTML may be related to the appearance of MN. Objectives: To verify the relationship between MN and the space under the DTML between the metatarsal heads of the third (M3) and the fourth (M4) metatarsals using US. Methods: This is a cross-sectional epidemiological study. The research study using the ultrasound (US) technique was carried out on 200 feet belonging to 100 patients aged 18 to 65 of both sexes, with a control group formed by 62 patients and a study group formed by 38 patients diagnosed with MN. Results: The presence of MN and the factors associated with it were studied in 100 patients using ultrasound (US). The assessment and comparison with US of the space inferior to the DTML between M3 and M4 in control groups and patients with MN show that patients with MN have a smaller size in the variable “h” (height or distance DTML-plantar skin), in the variable “b” (base or intermetatarsal distance M3 and M4) and in the variable “s” (surface of the parallelogram “h” × ”b”). The predictors of MN are a decrease in dimension “b” and an increase in weight. Sitting in an office chair and the use of a bicycle, due to equinus, have an influence on the space below the DTML, reducing it and promoting the appearance of MN. Conclusions: The two US measurements (“h” and “b”) in the space below the DTML are smaller in patients with MN than in the asymptomatic group. A shorter distance between M3 and M4, and an increase in BMI are predictors of MN.
