Background: Distal radius fractures are common, with volar locking plates widely used for fixation. Recent advancements with polyether ether ketone (PEEK) implants offer benefits including radiolucency and biocompatibility. However, data on the Avanti PEEK system for distal radius fractures is limited. This study analyzes a larger cohort to assess clinical and demographic factors associated with the system.
Methods: We conducted a retrospective review of 365 patients who underwent distal radius fracture fixation with the Avanti PEEK system between 2020 and 2024. Data on demographics, comorbidities, surgical details, functional outcomes (QuickDASH, PRWHE, ROM), and complications were analyzed.
Results:Complications included tenosynovitis (0.26%, 95% CI: 0.00-0.78%), tendon ruptures (0.26%, 95% CI: 0.00-0.78%), and pain requiring hardware removal (1.03%, 95% CI: 0.00-2.06%). There was no incidence of infection. The mean functional outcomes were: PRWHE 37.6 (95% CI: 34.2-41.1), Functional Subscore 20.3 (95% CI: 18.2-22.4), Pain Subscore 17.5 (95% CI: 15.9-19.2), and QuickDASH 30.6 (95% CI: 27.7-33.5). Range of motion (ROM) at 6 weeks, 3 months, and 6 months showed appropriate recovery (e.g., wrist flexion at 6 weeks: 43.7° (95% CI: 46.9°-50.7%); 3 months: 47.4° (95% CI: 51.1°-56.1%); 6 months: 40.8° (95% CI: 33.9°-56.9%)).
Conclusion:The Avanti PEEK system demonstrates favorable functional outcomes and low complication rates, suggesting it is a safe and effective alternative to traditional metallic fixation systems for distal radius fractures.
