Injuries to the distal tibiofibular syndesmosis can occur in conjunction with ankle fractures. Sagittal instability of the syndesmosis is more critical than coronal instability and must be taken into account when considering reduction and fixation of the syndesmosis. The purpose of this Technical Note is to report the technique of arthroscopically assisted reduction of sagittal-plane disruption of the distal tibiofibular syndesmosis. This ensures a comprehensive assessment of the pattern of syndesmotic disruption, which can aid anatomic reduction of the syndesmosis.
Varus malunion after subtalar arthrodesis is considered to be the worst deformity in hindfoot alignment. Poor clinical outcome is expected if there is more than 10° of varus malunion with lateral column overload. Open revision subtalar arthrodesis is associated with high rates of complications, especially involving soft tissue and nonunion. The purpose of this Technical Note is to describe the technical details of endoscopic revision subtalar arthrodesis in which the correction of varus malunion is performed with a minimally invasive technique, which may reduce the risk of soft tissue complications and nonunion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
