Spinal cord stimulation for recurrent painful neuromas of the foot

The authors report the case of a patient affected by recurrent neuromas of the interdigital nerves of the left foot that appeared after surgery for Morton's disease. Implantation of spinal cord stimulation (SCS) system was performed after three unsuccessful surgical revisions, which demonstrated the presence of multiple neuromas growing at endings of the stumps of the nerves and fasciculi. The patient developed chronic neuropathic pain localized within the third metatarsal region of the left foot. Conservative treatments failed and autonomous gait became impossible. SCS immediately abolished pain and the patient was able to perform her normal daily activities within 1 month. At our knowledge, this is the first report in literature of SCS successfully employed for recurrent and refractory pain due to Morton's neuroma.
