KEY FACTS

  • Terminology

    • Imaging

      • Diagnostic Checklist

        TERMINOLOGY

        • Synonyms

          • Plantar fasciitis: Jogger's heel, tennis heel, policeman's heel, heel spur syndrome, calcaneal spur syndrome, plantar fasciopathy
          • Plantar fibromatosis: Ledderhose disease, plantar fibroma
        • Definitions

          • Plantar fascia = multilayered fibrous aponeurosis, 1-2 mm thick, with medial, central, and lateral bands
            • Supports long and short plantar ligaments in maintaining longitudinal arches of foot
              • Innervated by medial calcaneal nerve and 1st branch lateral plantar nerve
                • Entrapment of 1st branch lateral plantar nerve (Baxter neuropathy) can simulate plantar fasciitis
            • Medial band is least significant
              • Inserts into 1st metatarsophalangeal joint
            • Central band is largest; originates from medial tuberosity of calcaneum
              • Divides in forefoot into 5 bands that insert onto plantar plates of metatarsophalangeal joints 
            • Lateral band inserts into base of 5th metatarsal bone
          • Plantar fasciitis: Degeneration ± fibroblastic proliferation of plantar fascia insertion to medial tuberosity of calcaneus
            • As there is no clear inflammatory component, plantar fasciopathy may be more favorable term
          • Plantar fibromatosis: Nodular fibroblastic proliferation of plantar fascia separate from calcaneus
