Functional outcomes of primary subtalar arthrodesis in sanders type IV calcaneal fractures, a case series()

BACKGROUND: Primary subtalar arthrodesis (PSTA) is a valid option in treating Sanders IV calcaneal fractures with few studies to assess its outcomes. METHODS: Seventeen patients with Sanders IV calcaneal fractures were managed by open reduction and primary subtalar arthrodesis. Functional outcomes were measured by AOFAS-AHS and FAAM-ADL. We also documented time to return to work, union rate, wound complications and the need for second surgeries. RESULTS: Fourteen patients were followed for two years. At final follow-up, the mean AOFAS-AHS score was 74.42 ± 1.95, while the mean FAAM- ADL score was 59.21 ± 1.6. CONCLUSION: PSTA is a valid option in treating these severe fractures. It may reduce the overall disability time.
