title: Endoscopic resection of a calcaneonavicular coalition.
abstract: Calcaneonavicular coalition is a congenital anomaly characterized by a connection between the calcaneus and the navicular. Surgery is required in case of chronic pain and after failure of conservative treatment. The authors present here the surgical technique and results of a 2-portals endoscopic resection of a calcaneonavicular synostosis. Both visualization and working portals must be identified with accuracy around the tarsal coalition with fluoroscopic control and according to the localization of the superficial peroneus nerve, to avoid neurologic damages during the resection. The endoscopic procedure provides a better visualization of the whole resection area and allows to achieve a complete resection and avoid plantar residual bone bar. The other important advantage of the endoscopic technique is the possibility to assess and treat in the same procedure-associated pathologies such as degenerative changes in the lateral side of the talar head with debridement and resection.
