The concept and technique of performing a
tibio-talo-calcaneal arthrodesis with bulk structural
allograft fixated using a retrograde compression intramedullary nail as a
salvage procedure for failed total ankle replacement is not new.
However, when compared with primary tibio-talo-calcaneal
arthrodesis a higher complication rate exists with nonunion occurring in >50%,
infection in 20% and below-knee amputation in nearly 20%.One reason for the
high incidence of complications may be that the fibula is nearly universally
resected with this procedure.
Instead, vascularized pedicled bone graft augmentation of
these salvage arthrodesis procedures to treat failed total ankle replacement
seems a logical choice to enhance union rate and functional limb salvage.
