Pathogenesis

Etiology

  • Trauma:
    • Over-reach.
    • Direct kick.
    • Kicking out at gates, metal sheeting.
    • Rolling and hitting sharp object.

Pathophysiology

  • Traumatic laceration at back of foot/limb   →   severance of flexor tendon(s)   →   loss of weight bearing capacity and stay apparatus   →   loss of limb stability   →   hyperextension of joint.
  • Hyperextension   →   tension and tearing of digital vessels and nerves   →   possible loss of digital arterial supply   →   limits healing capacity and   →   digital necrosis.
  • Calcaneal tendon:
    • Partial thickness tear can   →   full thickness with weight bearing.
