Answer

Candidates for TMA are chosen on the basis of limited irremediable tissue loss, typically occurring as a result of infection or ischemic changes in the foot. [3] The essential factor that must be taken into consideration is the individual patient's vascular sufficiency, which directly affects healing after amputation.

The clinical indications for TMA are as follows:

  • Chronic forefoot ulceration
  • Forefoot gangrene (multiple digits)
  • Combination of the above (potentially complicated by diabetes mellitus [4] )
  • Severe crushed forefoot (not salvageable)
