If the tibia and fibula form an angle greater than 90 degrees compared to the lateral border of the foot, what is the position of the foot?

When the tibia and fibula form an angle greater than 90 degrees in relation to the lateral border of the foot, this indicates that the foot is in a plantarflexed position. Plantarflexion occurs when the toes point away from the shin, which typically involves the ankle being positioned beyond a straight line, allowing for a more extended angle.

In this position, the heel is raised, and the foot points downward, resulting in the tibia and fibula creating an obtuse angle with respect to the lateral side of the foot. This can often be observed in activities such as standing on tiptoes or during specific exercises that require the toes to extend away from the body.

In contrast, dorsiflexion describes the scenario where the toes are brought closer to the shin, resulting in an angle that is less than 90 degrees, while neutral describes a resting position with the foot aligned neat to the tibia and fibula. Supination relates to the rolling of the foot outward, which does not specifically influence the angle formed by the tibia and fibula in relation to the lateral border of the foot.
