title: Endoscopic treatment of calcaneo-fibular impingement.
abstract: The calcaneo-fibular impingement syndrome is frequent after calcaneal fracture and is linked to the decreased space between the tip of the fibula and the lateral wall of the calcaneus. The reasons for the painful symptoms are mixed with both bony and soft tissue involvement. The abnormal bony contact between the lateral calcaneal cortex and the tip of the fibula depends mainly on the size and localization of the lateral exostosis of the calcaneal wall. The soft tissue impingement is due to the fibrosis and scar tissues in the lateral gutter and to the compression of the peroneal tendons in the retromalleolar groove and under the tip of the malleolus. A 2-portal endoscopic technique is described for the treatment of calcaneo-fibular impingement with bone resection, soft tissue debridement and peroneal tendons release. One of the advantages of this endoscopic technique is the possibility of an assessment and treatment of associated lesions in the same procedure. A subtalar joint fusion can be done before if needed under arthroscopic control. As this endoscopic technique is very efficient to relieve symptoms of calcaneo-fibular impingement and is focused on the most relevant symptoms, it can thus be indicated for most of cases of calcaneal malunions, whatever the type of malunion and depending of the painful symptoms.
