Weber Classification (Ankle Fractures)
Classifies ankle fractures by level of fibular fracture relative to the ankle syndesmosis to guide management.
Score interpretation
Weber A: Infrasyndesmotic fracture. Syndesmosis intact. Stable injury.
→ Non-operative: below-knee cast or aircast boot for 6 weeks. Partial weight-bear from day 1 if undisplaced. Orthopaedic outpatient follow-up.
Weber B: Transsyndesmotic fracture. Syndesmosis may be intact or disrupted. Stability determined by medial side.
→ Assess medial side (deltoid ligament / medial malleolus). If stable (intact medial side, no displacement): non-operative in cast. If unstable: ORIF. Stress XR if unclear.
Weber C: Suprasyndesmotic fracture. Syndesmosis disrupted. Usually unstable.
→ Operative management (ORIF) typically required. Syndesmotic screw if diastasis confirmed. Orthopaedic review. NWB until fixation.
