Post-Traumatic Avascular Necrosis of the Talus Treated by Vascular Pedicle Graft using Lateral Tarsal Artery

Avascular necrosis is a significant late complication of talar neck fracture. However, treatment for early stage avascular necrosis has been not established. Two patients with post-traumatic avascular necrosis of talus treated with vascular pedicle graft using lateral tarsal artery were reviewed to determine the efficacy of procedure. The procedure involved grafting the lateral tarsal artery and vein into a hole made in the talus through a anterolateral approach. Follow-up was 12 and 24 months respectively. Two patients had significant pain relief, improved function, no worsening of their radiologic staging. The results are promising enough to recommend consideration of this procedure in early stages of avascular necrosis.
