Unstable Weber B Fractures: Cast vs Surgery

Study compares treatment approaches for a type of lateral malleolus fracture deemed unstable on stress testing

Category	Detail
Condition	Unstable Weber B ankle fractures
Key Mechanisms	Assessment of fracture stability via external rotation stress testing
Target Population	Skeletally mature patients aged 16 years and older with isolated Weber B fibula fractures
Care Setting	Specialist university hospital trauma center

Cast immobilization showed no worse functional outcomes than surgery at 2 years post-injury.
Surgery remains the main treatment despite evidence supporting nonoperative options.
Treatment-related adverse events were more frequent in the surgical group.
No significant differences in secondary outcomes between cast and surgery.
A standard below-the-knee cast provides adequate stabilization for these fractures.

Surgery carries risks of treatment-related adverse events, including infections and delayed healing.

Patients with unstable Weber B ankle fractures and congruent mortise.

Cast immobilization is effective and may reduce the risk of surgical complications.

Prioritize nonoperative management when feasible for unstable Weber B fractures.
Ensure thorough patient education on the risks associated with surgical intervention.
