  • Pathophysiology
  1. Mechanisms: Joint degeneration with an increased risk of repeated Fracture and deformity
    1. Loss of proprioception
    2. Autonomic Dysfunction (vasomotor control loss)
  2. Typically affects weight bearing joints (knee, ankle and foot)
  • Causes

  2. Great joint instability and Hypermobility
  • Imaging
  1. Severe joint degeneration
  • Complications
  1. Wound ulcers (high risk of Osteomyelitis)
