Treatment of a patient with chronic causalgia after surgical removal of the neuroma in the second interdigital space

BACKGROUND: Morton’s neuroma is a common pathology of the forefoot. Etiopathologically, this disease can be attributed to nerve fibrosis, not a tumor. We now have various therapeutic options for neuromas, the most frequent of which is traction neurectomy. Recurrent pain affects up to 35% of patients with traction neurectomy, and one-third have recurrent stump neuroma produced by the proliferation of fibrous scar tissue around the remaining nerve elements. Conservative treatment methods are more commonly used to treat recurrent neuromas and residual pain, but surgical therapy is required in some cases. Despite the relatively high prevalence, the treatment of such patients is a challenging task for orthopedic traumatologists. CLINICAL CASE DESCRIPTION: We show the effective treatment of a patient with stump neuroma and primary Morton’s neuroma in two stages. The second interdigital space nerve was transposed, and the deep, transverse metatarsal ligament of the third interdigital space was dissected in the first stage. The second stage consists of removing the sensitive scar, resecting the plantar nerve of the third interdigital space, and performing a Weil osteotomy. CONCLUSION: Consistent use of conservative surgical procedures, appropriate revision of the subcutaneous nerve, and excision of a sensitive scar allows for a successful therapeutic outcome, pain alleviation, and the ability to wear normal shoes. © Eco-Vector, 2023.
