The tarsocrural (TC) joint articulates the distal end of the tibia with the medial and lateral trochlear ridges of the talus. The proximal tubercle of the talus (PTT), on the proximal and medial aspect of the talus, has a groove through which the medial digital flexor tendon runs, which divides the PTT into a medial and plantar portion (Espinosa et al., 2013;Nixon, 2020). It is also an insertion point for a portion of the medial short collateral ligaments of the TC joint (Verwilghen et al., 2010). The TC joint is divided into distinctive compartments. Arthroscopic access to the four pouches of the TC joint is typically utilised for surgical intervention of TC joint pathology.Arthroscopic access to the plantaromedial pouch permits evaluation of the medial malleolus, the abaxial aspect of the medial trochlear ridge (MTR), the middle or deep part of the short medial collateral ligament and the long medial collateral ligament (Kummerle & Kummer, 2013).Fractures due to trauma are relatively common in foals, frequently secondary to external traumatic events. Fractures of the plantar region of the talus are infrequent in horses, and often difficult to diagnose. Though rarely reported, the most frequently identified fracture in the plantar aspect of the TC joint is fracture j5 of the PTT, and these fractures are usually extra-articular (Espinosa et al.,
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.
