The standard approach was used for all surgeries. Graft materials included b-tricalcium phosphate, demineralized bone matrix, iliac crest autograft and allograft, and allograft cancellous chips. Successful subtalar fusion was determined clinically and radiographically.<h4>Results</h4>There was an 88% (37/42) union rate without graft use and an 83% (78/93) union rate with bone graft use. Odds ratio of union for graft versus no graft was 0.703 (95% CI, 0.237-2.08). The average time to union in the graft group was 3 ± 0.73 months and 3 ± 0.86 in the non-graft group, with no statistically significant difference detected (p = 0.56).<h4>Conclusion</h4>Graft use did not improve union rates for subtalar arthrodesis. <b>Level of Evidence IV, Case Series.</b>ArthrodesisBone transplantationCalcaneusSubtalar jointTransplantation, homologousJournal article2023-05-31
