| Popis: | Background: Nonunion after ankle or hindfoot arthrodesis is associated with poor outcomes. Cellular bone allograft is an alternative to autograft for use in these procedures. The purpose of this study was to prospectively evaluate the early efficacy and safety of cellular bone allograft use in hindfoot and ankle arthrodesis procedures. Methods: Fourteen patients undergoing hindfoot or ankle arthrodesis supplemented with cellular bone allograft were prospectively enrolled. Computed tomography (CT) scans were obtained postoperatively at set time points and reviewed by 3 fellowship-trained foot and ankle surgeons as well as 1 musculoskeletal radiologist. Primary outcome was CT-verified union, defined as >25% of joint surface. Complications were recorded and revision procedures offered as indicated. Results: CT-verified union rate during the study period was 76.7% (23 of 30 joints). Union was 100% for the ankle joint (2 of 2), 50% for the talonavicular joint (5 of 10), 100% for the calcaneocuboid joint (8 of 8), and 80.0% for the subtalar joint (8 of 10). One patient underwent revision fusion procedure, and 1 patient underwent hardware removal during the study period. Conclusion: Our initial experience suggests that use of cellular bone allograft augmentation in hindfoot and ankle arthrodesis may offer an alternative to autograft without potential of donor site morbidity. Level of Evidence: Level IV, case series. |
