Outcomes of triple arthrodesis with IOFIX type fixation: A prospective study.

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.
