Introduction:
Tibiotalocalcaneal (TTC) arthrodesis is a critical surgical intervention for advanced hindfoot and ankle pathologies, offering pain relief, stabilization, and functional alignment restoration. Intramedullary nail fixation, particularly with dynamic compression (DC) nails, has emerged as a promising solution for addressing high nonunion rates associated with standard static compression (SC) nails. This study compares union and complication rates between DC and SC nails in TTC arthrodesis using the Nationwide Readmissions Database.
Methods:
This retrospective cohort study used the Nationwide Readmissions Database to identify cases of TTC fusion with DC and SC nails based on ICD-10-PCS codes. Propensity score matching (1:1) controlled for confounders, including age, sex, and comorbidities. Primary outcomes included complications such as thromboembolism, wound dehiscence, cellulitis, implant-related complications, nonunion, malunion, and infections. Secondary outcomes included 30-day and 31-90-day readmission rates. Statistical significance was set at P < 0.05.
Results:
The study analyzed 311 cases (149 with DC, 162 with SC). Demographic and comorbidity distributions were balanced after matching. Nonunion rates were significantly lower in the DC group (6.0%) compared with the SC group (17.3%; P = 0.002). Overall complication rates were comparable (DC: 30.2% vs. SC: 35.2%, P = 0.350).
Discussion:
DC devices demonstrated markedly reduced nonunion rates compared with SC nails, likely because of the continuous compression provided by the nitinol-based design. This novel finding validates the biomechanical advantages of devices using DC in TTC fusion and aligns with previous research advocating for such devices.
Conclusion:
DC nails offer an advancement in TTC arthrodesis by markedly reducing nonunion rates. Future studies should focus on cost-effectiveness, long-term outcomes, and patient-specific optimization to further refine treatment protocols.
