Combined Total Talus Replacement and Total Ankle Arthroplasty

$25.00

Avascular necrosis (AVN) of the talus remains a clinical challenge with suboptimal outcomes after treatment. In cases of extensive disease, the insufficient blood supply leads to a high rate of complications including non-union after surgical treatment. This, in conjunction with the development of premature adjacent arthritis represents a challenge for the treating surgeon. Nowadays, total ankle arthroplasty is a reasonable option for the treatment of end-stage ankle arthritis with improved short- and long-term outcomes. We present a technique for patients with end-stage ankle arthritis associated to extensive talar osteonecrosis, and patients with prior total ankle replacement and talar component collapse due to AVN. This technique provides a more anatomic treatment for patients with severely deficient bone stock due to talar necrosis with ankle arthritis or failed ankle replacement. Nonetheless, evaluation of the outcomes at long-term is needed. (Journal of Surgical Orthopaedic Advances 29(4):244–248, 2020)
