ABSTRACT
Longitudinal plantar approaches are generally considered at risk for wound healing
problems. Thus, we wanted to investigate long-term outcomes after a primary Morton's
neuroma excision through a longitudinal plantar approach. A retrospective study of
patients with primary neuroma excision was conducted. Twenty-four patients (28 feet)
were evaluated at a mean 9-year follow-up (range, 6-14) by a single trained examiner
using a specific postoperative evaluation protocol, including AOFAS Forefoot subjective
and objective scores. Good-to-excellent outcomes were reported in 25 (89.3%) cases.
A hypertrophic scar formation and keratosis occurred in only 2 cases (7.1%). All the
patients, with a single exception, achieved full weightbearing with a postoperative
shoe from the first day after the operation. A longitudinal plantar approach can lead
to long-term, good-to-excellent outcomes with no case of recurrence or reoperation.
Accurate wound closure and immediate weightbearing with a postoperative shoe can minimize
the rate of complications. This approach should be considered for primary resection
of Morton's neuromas.
