Case Series: Allograft Tibiotalocalcaneal Arthrodesis Utilizing Fresh Talus

Blog Article

Background: Talar body osteonecrosis can be a difficult condition to treat.Recent reports highlight a high rate of failure with the use of femoral head allograft.Additionally, higher rates of failure have been reported in diabetics and smokers.

Our emtek 2113 institution attempted a novel technique utilizing fresh allograft talus in attempt to improve on a reported 50% nonunion rate.Methods: Five patients who underwent tibiotalocalcaneal (TTC) fusion utilizing fresh talar allograft were clinically and radiographically reviewed to evaluate fusion rates and functional outcomes.Results: Our case series of 5 patients had a 100% union rate, including 2 former smokers and 2 diabetic patients.

There were no infections or complications.Functional outcomes also improved in our series of patients postoperatively as noted by their FAAM and SF-36 scores.Conclusion: TTC fusion using fresh allograft talus has a higher union rate than reported with femoral head allograft.

This case series requires g5210t-p90 further study to evaluate whether this technique can be used beyond patients with osteonecrosis of the talus.Level of Evidence: Level IV, case series.
