Accessory bones of the ankle. [13]Accessory bones at the ankle mainly include: Os subtibiale, with a prevalence of approximately 1%. [14] It is a secondary ossification center of the distal tibia that appears during the first year of life, and which in most people fuses with the shaft at approximately 15 years in females and approximately 17 years in males.
Type 1: An os tibiale externum is a 2–3 mm sesamoid bone in the distal posterior tibialis tendon. Usually asymptomatic. Type 2: Triangular or heart-shaped ossicle measuring up to 12 mm, which represents a secondary ossification center connected to the navicular tuberosity by a 1–2 mm layer of fibrocartilage or hyaline cartilage. Portions of ...
Fracture of the navicular bone. The tibialis posterior is the only muscle that attaches to the navicular bone. The main portion of the muscle inserts into the tuberosity of the navicular bone. [3] An accessory navicular bone may be present in 2–14% of the general population. [4] [5] [6]
Tibial tuberosity fractures are infrequent fractures, most common in adolescents. In running and jumping movements, extreme contraction of the knee extensors can result in avulsion fractures of the tuberosity apophysis. [3] A cast is all that is required if the fragment is not displaced from its normal position on the tibia. However, if the ...
Studies have shown [3] that bimalleolar fractures are more common in women, people over 60 years of age, and patients with existing comorbidities. [3] A trimalleolar fracture is a fracture of the ankle that involves the lateral malleolus, the medial malleolus, and the distal posterior aspect of the tibia, which can be termed the posterior ...
The Gosselin fracture is a V-shaped fracture of the distal tibia which extends into the ankle joint and fractures the tibial plafond into anterior and posterior fragments. [1] The fracture was described by Leon Athanese Gosselin, chief of surgery at the Hôpital de la Charité in Paris. [2]
The Danis–Weber classification (often known just as the Weber classification) is a method of describing ankle fractures. It has three categories: [1] Type A. Fracture of the fibula distal to the syndesmosis (the connection between the distal ends of the tibia and fibula). Typical features: below level of the ankle joint; tibiofibular ...
