Metatarsalgia Etiology / Epidemiology / Natural History

  •  Metatarsalgia = nonspecific term for pain in the lesser metatarsalphalangeal joints.

Metatarsalgia Anatomy

  • The extensor digitorum longus and brevis are generally innervated by the deep peroneal nerve.
  • Plantar plate consists of the plantar aponeurosis and the plantar capsule.
  • Plantar fat pad: a protective fatty cushion beneath the metatarsal heads; normally connected to the bases of the phalanges.

Metatarsalgia Clinical Evaluation

  •  Anterior drawer test: hold the metatarsal head between the index finger and thumb; grasp the base of the proximal phalanx with the other hand and apply a dorsally directed force. Dorsal displacement and pain indicate metatarsophalangeal joint instability or MTP synovitis.

Metatarsalgia Xray / Diagnositc Tests

  •  Foot films generally normal.  

Metatarsalgia Classification / Treatment

  • Secondary treatment = rocker bottom soled shoe

Metatarsalgia Associated Injuries / Differential Diagnosis

  • Claw toe
  • Monoarticular nontraumatic synovitis
  • Morton's Neuroma
  • Metatarsophalangeal joint instability
