Endoscopic excision of symptomatic nonunion of anterior calcaneal process.

Most fractures of the anterior process of the calcaneus are successfully treated with cast immobilization. Large fragments might be amenable to open reduction and internal fixation. The correct initial diagnosis and treatment are important, particularly if the fracture fragment is large. An improper initial diagnosis will lead to painful nonunion requiring surgical intervention. We present a case of symptomatic nonunion of the anterior calcaneal process that was successfully treated by endoscopic resection of the fragment. The adjacent structures can be examined arthroscopically for concomitant lesions and treated accordingly.
