Ankle arthrodesis. Clinical and conceptual applications.

Ankle fusion provides an excellent salvage for an otherwise intolerable deformity or painful joint derangement. It is the only available alternative for a failed ankle prosthesis. It produces a serviceable foot when done in proper perspective for the appropriate indication. It produces a good result when consolidation occurs and the remaining tarsal joints have preserved integrity. Improvement in occupational and daily activities can be anticipated when arthrodesis and correct alignment are obtained.
