title: Isolated talonavicular joint arthrodesis through minimal incision surgery.
abstract: 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.
  
  
  CONCLUSIONS
  Isolated TNA by MIS could be an option for the treatment of TN arthritis, especially for patients at greater risk of wound healing complications.
  
  
  METHODS
  Level IV, case series.
