- Discussion:
- condition of fibula, whether frxed or intact, determines angulatory
behavior of these frx under wt bearing and functional conditions;
- isolated frx of
lateral plateau w/ intact fibula do not tend to collapse
further because of the support of the fibula;
- in contrast, frxs of both lateral plateau and fibula have tendency to collapse
into valgus because of the loss of support of the fibula;
- fractures of both condyles do not collapse or angulate when proximal
fibula is fractured and displaced;
- however, if fibula is intact, the
medial plateau usually collapses
creating a varus deformity;
