We have reviewed a single surgeon's experience with isolated talonavicular
fusion in 16 patients with talonavicular arthritis. Fixation was either by
staples or screws. Fifteen solid unions were achieved in the 16 patients wh
o were followed (mean: 51 months). The average Ankle-Hindfoot Scale improve
d from 77.2 preoperatively to 92.9 postoperatively (p < 0.001). Subjectivel
y, 15 patients were satisfied and one patient dissatisfied with the results
. Further osteoarthritis in the adjacent joints was noted in five patients.
We concluded that isolated talonavicular fusion is an effective method of
treatment of talonavicular arthritis regarding pain relief and functional i
mprovement. Though osteoarthritis was found in some adjacent joints postope
ratively, the results were still satisfactory.
