The syndesmotic ligament connects the two bones of the leg; this is often referred to as the ankle sydesmosis, or just syndesmosis. These bones, the tibia, and fibula are between the knee and ankle joints. The tibia is the larger shin bone that supports most of the weight of the body, and the fibula is the smaller bone on the outside of the leg.
Arthritis can affect any of your joints, including those in your feet. Joint damage from arthritis can cause pain, swelling, and physical changes to the joints.
A Maisonneuve fracture is a specific type of ankle fracture that occurs when the ankle is forcefully twisted outwards (external rotation). The fracture is important because treatment almost always requires surgery, and without a careful examination of the ankle (and the knee), it's possible to misdiagnose this injury.
