Current understanding of interdigital neuroma is based on Gauthier’s conclusion in 1979 that the symptom complex was a result of an entrapment neuropathy of the interdigital nerve by the overlying transverse metatarsal ligament. Presently, no definitive single etiology has been confirmed. Additional potential pathoetiologies include the aberrant anatomy of the plantar nerve in this location, trauma and extrinsic mass effect above or below the level of the transverse metatarsal ligament.(3,6) The histological appearance of the affected nerve, however, is consistent and suggests that “neuroma” is a misnomer for this condition. The nerve tissue demonstrates demyelination and deposition of amorphous eosinophilic material, but no exuberant proliferation of nerve endings characteristic of neuroma.(3)
