Table 2.

Indications for ankle arthrodesis.

  • - Idiopathic end-stage osteoarthritis (OA) of the ankle (Tanaka 3B, 4)

  • - Post-traumatic ankle OA (80% of total)

  • - Inflammatory arthritis

  • - Young and active patients*

  • - Avascular necrosis of the talus^

  • - Infectious sequelae

  • - Congenital malformations

  • - Neurological foot with malalignment

  • - Failed total ankle arthroplasty (TAA) ^^

*Classic indication currently under debate: there are good results of TAA in patients under 55 years of age. ^In severe necrosis (>75% of the total talus) tibiotalocalcaneal (TTC) arthrodesis may be necessary to provide stability. ^^In cases of severe bone stock loss during TAA revision surgery, TTC arthrodesis with allograft is the technique of choice.
