ABSTRACT
We have reviewed a single surgeon's (M.S.) experience of talonavicular arthrodesis in 7 feet in 7 patients with isolated talonavicular arthritis. A standard dorsomedial approach was used to the talonavicular joint. Fixation was performed with 5.5-mm, partially threaded, cancellous screws. The visual analog scale for the foot and ankle (VASFA) was used to measure the preoperative and postoperative results in the categories of pain, function, other complaints, and total score. The follow-up period was 17 to 90 months (mean 48). The overall VASFA score ranged from +19.2 to +57.6 (mean +33.2, p < .01). The VASFA score for pain ranged from +19 to +74.8 (mean +51.3, p < .01). The VASFA score for function ranged from +12.5 to +68.2 (mean +28.3, p < .01). The VASFA score for other problems ranged from +12 to +45.8 (mean +25.5, p < .01). None of the 7 feet required revision, and all 7 patients were satisfied with the outcome and would have the operation again. We have concluded that, taking into account the small power of the present study, talonavicular arthrodesis is a successful treatment for isolated talonavicular arthritis.
