Comparative study of subtalar arthrodesis after calcaneal frature malunion with autologous bone graft or freeze-dried xenograft
Fifteen consecutive patients with hindfoot pain after calcaneal fracture underwent subtalar arthrodesis using interposition iliac crest bone graft. Outcome and correction of calcaneal collapse were assessed before and after surgery with clinical examination, visual analogue scores, and standard x-rays while weightbearing. Eleven of the 15 patients were satisfied with the procedure. There were four failures due to transverse tarsal joint arthritis, overcorrection, and reflex sympathetic dystrophy. Radiographic examination revealed restoration of heel height, with 100% union rate of the arthrodesis. The described technique allows arthrodesis and correction of calcaneal collapse after calcaneal fracture.
