Final answer:
Tibial torsion refers to medical conditions involving the bones and ligaments of the leg, specifically injuries like high ankle sprains and Pott's fractures, which affect the tibia and fibula.
Step-by-step explanation:
Tibial torsion is a term related to the medical field, specifically to orthopedics, which pertains to injuries and conditions of the bones and joints. When one experiences an injury that leads to a lateral twisting of the leg while the foot is planted, it can result in the stretching or tearing of the tibiofibular ligaments, leading to a syndesmotic ankle sprain or a "high ankle sprain". This injury is associated with the syndesmosis — a fibrous joint that connects the distal ends of the tibia and fibula above the ankle.
Another related injury is an eversion sprain, which involves the stretching of the deltoid ligament on the medial side of the ankle. If a person lands awkwardly or receives a forceful hit while the foot is planted, this can lead to a Pott's fracture and dislocation of the ankle joint. In such cases, the talus is displaced laterally, which can result in the fracture of the distal fibula and, in severe cases, can also shear off the posterior margin of the tibia.
