Abstract Background Foot and ankle arthrodesis procedures are frequently performed in concert with the utilization of bone grafts. However, the availability of autologous bone is often limited, inaccessible, or not suitable, thus there is a need for bone graft substitutes with equally effective clinical outcomes. A next generation integrative bone matrix (IBM) has been developed that has intrinsic osteogenic, osteoconductive, and osteoinductive characteristics, and is a promising solution to mitigate complications such as nonunion and reduce the need for autologous bone graft harvest. Methods The charts of twenty subjects undergoing foot and ankle fusion procedures with INFLUX™ SPARC, a novel IBM, were retrospectively reviewed to determine initial clinical safety and efficacy of this next generation bone graft. Endpoints included the presence of complications or surgical reintervention, fusion rates as determined by standardized radiographic films, and patient-reported outcome measures at various time points up to 24 weeks. Results No major complications or surgical reinterventions were observed in this study. Complete radiographic fusion was achieved in all subjects by 24 weeks, with a mean overall fusion time of 8.5 ± 4.8 weeks. Subjective pain, function, and quality of life outcomes showed consistent improvements throughout the follow-up period, and all subjects (100%) achieved the minimum clinically significant mean improvements for all measures by week 24. Conclusions This study supports the use of this new IBM as a promising alternative to autologous bone grafting, offering high fusion success rates, low complications, and clinically meaningful improvements in patient-reported outcomes, particularly in higher-risk patient populations. Future investigations are needed to confirm these findings in larger and longer-term studies, and to explore the broader applications of this innovative bone graft. |
