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.
