Unstable Weber B Fractures: Cast vs Surgery

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

1

Cast immobilization for unstable Weber B ankle fractures yields functional outcomes comparable to surgery at 2 years postinjury.
2

The SUPER-FIN trial involved 126 patients with unstable Weber B fractures, randomly assigned to cast or surgical treatment.
3

No significant differences were found in secondary outcomes, including pain and ankle function, between cast and surgery groups.
4

Surgery was associated with more treatment-related complications, including infections and hardware removal procedures.
5

The study supports conservative treatment approaches for maintaining ankle mortise congruency in isolated unimalleolar fractures.
