Study Notes
Weber's Classification of Ankle Fractures
- Type A: Characterized by a transverse fibula fracture occurring below the syndesmosis, potentially accompanied by a fracture of the medial malleolus.
- Type B: Defined by an oblique fibula fracture aligned with the level of the syndesmosis, also possibly associated with a medial malleolus fracture.
Variants of Type B Fractures
- Type B1: Represents an isolated Type B fracture.
- Type B2: This variant includes a Type B fracture accompanied by a lesion affecting the medial side, such as a malleolus or ligament injury.
- Type B3: Involves a Type B fracture along with a medial lesion and a fracture at the posterolateral aspect of the tibia.
Type C Fractures
- Type C: Refers to fractures positioned above the syndesmosis, which become disrupted and widened, often linked with a medial malleolus fracture affecting the deltoid ligament.
- Type C1: Involves a diaphyseal fracture of the fibula, presenting as a simple fracture.
- Type C2: Similar to Type C1 but characterized by a complex diaphyseal fracture of the fibula.
- Type C3: Associated with a fracture of the proximal tibia.
Surgical vs. Conservative Treatment
- Surgery is indicated for bimalleolar fractures, undisplaced Type C fractures, and any displaced Type A, B, or C fractures.
- Undisplaced Type A and B fractures can typically be managed with conservative treatment.
Healing Timeline
- Tibia fractures generally take about 10-12 weeks to heal.
- Fibula fractures have a shorter healing period of around 6 weeks.
Ankle Ligament Anatomy
- The deltoid ligament comprises four key structures: the anterior and posterior tibiotalar ligaments, the tibionavicular ligament, and the tibiocalcaneal ligament.
- Lateral ankle ligaments include the anterior and posterior talofibular ligaments, the calcaneofibular ligament, and the lateral talocalcanean ligament.
