The ankle joint is formed by the bony mortise of the tibia and fibula around the talar trochlea. Its inherent bony stability depends on mortise integrity — fibular fracture or syndesmotic disruption widens the mortise and increases tibiotalar contact pressure dramatically. The ankle joint is the most commonly injured major joint in sport.
Ankle fractures are classified by the Weber system based on fibular fracture level relative to the syndesmosis. Operative versus non-operative management decisions hinge on ankle mortise stability — an unstable fracture pattern (widened medial clear space, fibular fracture with syndesmotic injury) requires ORIF. Total ankle arthroplasty for end-stage ankle osteoarthritis has improved significantly with third-generation implants.
