Calcaneonavicular coalition treated by resection and interposition of the
extensor digitorum brevis muscle. Gonzalez-P; Kumar-SJ Alfred I. duPont Institute, Wilmington, Delaware 19899. J-Bone-Joint-Surg-Am. 1990 Jan; 72(1): 71-7 Seventy-five feet in forty-eight patients that had calcaneonavicular coalition were evaluated at two to twenty-three years after resection of the coalition and interposition of the extensor digitorum brevis muscle. The result was excellent or good in fifty-eight feet (77 per cent). Three feet that were rated initially as having a fair result improved over time, and at the last follow-up the result in those feet was rated as good. Only five feet (7 per cent) had a poor result. The best results were in patients who had a cartilaginous coalition and who were less than sixteen years old at the time of operation.
