- see: stability of weber b fractures:
- isolated Weber B fractures (no medial injury) can be treated w/ a cast if there is upto 3 mm of fibular displacement;
- it has been observed that x-rays tend to over-estimate displacement (as compared to CT scans) and because the apparent displacement may be mostly due to
internal rotation of the proximal fibula as compared to pathologic external rotation of the external fibula;
- some orthopaedist will treat the fracture in a short leg cast and will have the patient return to clinic in 3 days;
- if displacement occurs, then the frx is unstable and requires ORIF;
- alternatively the surgeon can order a "AP stress view" w/ a lateral directed force inorder to look for displacement
