Retrograde Intramedullary Nail With Femoral Head Allograft for Large Deficit Tibiotalocalcaneal Arthrodesis.

Background: Large bone defects present a difficult task for surgeons when performing single-stage, complex combined hindfoot and ankle reconstruction. There exist little data in a case series format to evaluate the use of frozen femoral head allograft during tibiotalocalcaneal arthrodesis in various populations in the literature.

Methods: The authors evaluated 25 patients from 2003 to 2011 who required a femoral head allograft and an intramedullary nail. The average time of final follow-up visit was 83 ± 63.6 weeks (range, 10-265).

Results: Twelve patients healed the fusion (48%). Twenty-one patients resulted in a braceable limb (84%). Four patients resulted in major amputation (16%).

Conclusion: This series may allow surgeons to more accurately predict the success and clinical outcome of these challenging cases.

Level Of Evidence: Level IV, case series.
