Isolated talonavicular (TN) arthrodesis has been described for treatment of rigid and flexible PCFD for patients that are older and less active whose deformity is still correctable through the TN joint. The purpose of this study was to evaluate radiographic and clinical outcomes in patients with PCFD treated with isolated triplanar correction with a TN joint arthrodesis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Forty-nine patients (53 feet) with flexible PCFD underwent isolated TN arthrodesis. Weightbearing radiographs were performed pre- and postoperatively, and measurements included lateral talar\u2013first metatarsal angle, calcaneal pitch, TN coverage angle, and the anteroposterior (AP) talar\u2013first metatarsal angle. The Foot and Ankle Ability Measure (FAAM) and Veterans-Rand 12-Item Health Survey (VR-12) scores were also collected.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Thirty-five females and 14 males were evaluated with a mean age of 63\u2009years, at an average follow-up of 41.3\u2009months. Significant improvements were found radiographically. Lateral radiographs demonstrated improvements in lateral talar\u2013first metatarsal angle from 25.2 degrees preoperatively to 9.5 degrees postoperatively ( P\u2009&lt;\u2009.001) and calcaneal pitch from 14.9 degrees preoperatively to 17.5 degrees postoperatively ( P\u2009&lt;\u2009.001). AP radiographs showed the TN coverage angle improving from 35.0 degrees to 4.9 degrees postoperatively ( P\u2009 &lt;\u2009.001) and AP talar\u2013first metatarsal angle improving from 17.3 degrees to 5.9 degrees postoperatively ( P\u2009&lt;\u2009.001). Clinical outcomes were improved in the FAAM pain score (48.6 to 39.2, P\u2009=\u2009.130), FAAM ADL score (53.8 to 69.2, P\u2009=\u2009.002), FAAM Sport score (29.5 to 40.7, P\u2009=\u2009.099), and the overall FAAM score (47.7 to 63.1, P\u2009=\u2009.006).
