title: Results of the surgical treatment of calcaneo-navicular coalito.
abstract: We present the results after surgical treatment in 15 patients who suffered from calcaneo-navicular coalitio. A total of 20 operations were performed on 19 feet (3 T-arthrodesis, 5 simple resections, 9 resections with fat interposition, 3 resections with muscle interposition). At the time of follow-up, the patients were examined clinically and radiologically. In addition, different functional tests were performed (heel-tip test, balance test, single-leg high jump, single-leg jumping course). Ten of 17 patients who underwent radiographic study at the follow-up had a successful result. Patients who had a coalitio showed a tibial rotation (heel-tip test) of 11.5 degrees, and those patients without a coalitio had a tibia rotation of 20.3 degrees. Concerning the functional outcome, 12 of 17 patients had a successful result. The range of motion of the subtalar joint did not correlate with the functional capacity of the ankle. Seven of 20 patients subjectively judged the outcome as a failure. The worst results were found in patients with pre-existing degenerative changes at the time of resection.
