In this retrospective review, a control group of patients undergoing subtalar joint arthrodesis using a conventional bone graft was compared to a matched study grouputilizinga novel synthetic biphasic calcium phosphate (BCP) bone graft with advanced surface topography.Material and methods: Seventeen consecutive patients underwent subtalar joint arthrodesis using a novel BCP with a unique submicron surface topography, either as a standalone graft or mixed with bone marrow aspirate. Fusion outcomes were assessed via radiographs at six-weeks and twelve-weeks. Clinical outcomes were assessed via weight bearing status at six-weeks and twelve-weeks. These results were compared to a matched study group of 15 patients undergoing subtalar joint arthrodesis using a conventional bone graft.Results: Seventeen of seventeen (100%) ofpatients completed full follow up. Twelve ofseventeen patients had complete fusion at 12 weeks (70%)and four of seventeen patients (23%) had partial fusion at 12 weeks. One ofseventeen (5%) had revision arthrodesis. All patients were 100% weight bearing at 12 weeks. In the control group, fifteen of fifteen(100%) of patients completed full follow up. At 12 weeks, seven of fifteen (46%) had complete fusion, seven of fifteen (46%) had partial fusion, and one (6%) did not fuse and went on to revision surgery.Discussion and conclusions: This novel submicron surface topography BCP offers a promising bone graft substitute for arthrodesis of the subtalar joint. 0 0 0 0
