9    Neuropathic Osteoarthropathy

Definition

Neuropathic osteoarthropathy refers to massively destructive atrophic/hypertrophic joint disease of neurogenic origin.

Pathology

  exact cause unknown (proprioceptor impairment?)

  mechanical and vascular factors contribute equally to subsequent disintegration of the knee joint

  neurotraumatic causes of vascular changes lead to productive and resorptive joint changes

  increased vulnerability of bone to normal and increased mechanical stresses

Etiology

  tabes dorsalis

  amyloidosis

  congenital form

  knee joint extremely rarely involved in:

Clinical Signs

  joint swelling

  hypermobility of the joint

  uncharacteristic pain symptoms ranging from none to massive pain

  depending on underlying disease

Diagnostic Evaluation

(→ method of choice)

Recommended Radiography Projections

  anteroposterior (AP)

  lateral

Findings (Fig. 9.1)

  marked sclerosis

  articular destruction

  fragmentation
