Background:
The aim of this study was to evaluate the patient reported outcome measures (PROMS), radiological outcome and complications when performing a triple arthrodesis using the IOFIX system for the talonavicular and calcaneocuboid joints.
Methods:
Data was collected prospectively. Twenty-nine consecutive patients were reviewed 1 year postoperative. Outcomes analysed were rate of fusion, American Orthopaedic Foot and Ankle Society (AOFAS) score, Visual Analogue Scale (VAS), patient satisfaction and complications.
Results:
Complete fusion was achieved in 90 %. The mean preoperative AOFAS score improved from 42 (95 % confidence interval: 22-43) to 75 (95 % confidence interval 67-82) postoperative and the mean VAS improved from 6.5 (95 % confidence interval 4.9-8.6) to 4 (95 % confidence interval 3.1-4.9), p < 0.001. There was an early complication rate of 13 %. After 1 year 86 % were satisfied and there was a complication rate of 3 %.
Conclusions:
This study suggests that the IOFIX system offers a reliable and performant alternative technique for patients undergoing a triple arthrodesis.
Level Of Evidence:
Level II, prospective cohort study.
