What type of joint joins the distal end of the tibia and fibula?

The correct response highlights that the joint connecting the distal ends of the tibia and fibula is classified as a syndesmosis. This type of joint is a fibrous joint in which the bones are connected by a ligament or an interosseous membrane. In the case of the distal tibiofibular joint, the fibrous tissue serves to stabilize and maintain the positions of the two bones, allowing for a small degree of movement while ensuring integrity during weight-bearing and locomotion.

Understanding the characteristics of syndesmosis provides insight into its functional importance, particularly in relation to the ankle's stability. This joint type is essential for proper walking mechanics, as it helps absorb and distribute the forces that occur during activities like running and jumping. In contrast, other joint types listed, such as synovial or ball and socket joints, allow for greater mobility rather than stability, which differentiates them from the syndesmosis at the distal end of the tibia and fibula.
