Medical Eponyms

Morton metarsalgia (1876)

In 1876 Morton described a series of 15 patients of his own and one of a colleague who all shared the same complaints, which he termed metatarsalgia and which he attributed to an injury to the fourth metatarsophalangeal joint.

  • Morton neuroma – benign, perineural fibrotic lesion of a common digital nerve
  • Morton neuralgia, metatarsalgia (1876)


In 1835, Filippo Civinini of Pistoja (1805-1844) described in the anatomic letter entitled “Su un nervoso gangliare rigonfiamento alla pianta del piede” (“On the neural ganglion swelling of the foot sole“) – the fusiform (gangliare) swelling (rigonfiamento) in the common plantar digital nerve to the third interspace. However there was no clinical description (metarsalgia) involved in this report.

Review of the historical writings demonstrates that Morton did not describe a painful condition related to a common plantar digital nerve of any web space but rather a painful condition related to the fourth metatarsophalangeal joint. He treated this painful condition by resection of the joint and the nerves, probably on both sides of that joint.
