Abstract

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.

摘要

背景

本研究的目的是评估在使用IOFIX系统对距舟关节和跟骰关节进行三关节融合术时患者报告的结局指标（PROMS）、影像学结局和并发症。

方法

前瞻性收集数据。对连续29例患者进行术后1年的随访。分析的结局指标包括融合率、美国矫形足踝协会（AOFAS）评分、视觉模拟量表（VAS）、患者满意度和并发症。

结果

90%实现了完全融合。术前AOFAS评分均值从42（95%置信区间：22 - 43）提高到术后的75（95%置信区间67 - 82），VAS均值从6.5（95%置信区间4.9 - 8.6）提高到4（95%置信区间3.1 - 4.9），p < 0.001。早期并发症发生率为13%。1年后，86%的患者满意，并发症发生率为3%。
