Background: The purpose of this study was to analyze bony fusion and functional outcomes after talonavicular arthrodesis (TNA) using an original minimally invasive surgery (MIS).
Methods: There was a total of 11 feet in 11 patients who underwent TNA and were followed up for 47 months (range 40.8-53.1). Functional outcomes were measured by AOFAS and quality of life by eight sections of SF-36.
Results: Radiographic and clinical consolidation was achieved in 10 of 11 cases. In the AOFAS score, physical function improved a mean of 34.4 points (95% CI: 23.2-45.6; p<.0001) and pain improved a mean of 23.6 points (95% CI: 17.4-29.8; p<.0001). One osteoporotic and rheumatic patient had a non-union. No cases of early complications, such as wound infections, neurovascular damage or delayed wound healing, occurred.
Conclusion: Isolated TNA by MIS could be an option for the treatment of TN arthritis, especially for patients at greater risk of wound healing complications.
Level of evidence: Level IV, case series.
