Flexion-type Salter II fracture of the proximal tibia. Proposed mechanism of injury and two case studies.

An uncommon fracture of the proximal tibial epiphysis is described in two cases. A flexion-type Salter II fracture of the proximal tibia resulting from a partially closed physis can be reduced easily and appears to have no long-lasting effects. Radiographic review of the adolescent knees showed that physeal closure of the proximal tibial epiphysis proceeds from posterior to anterior, thereby making this particular fracture more likely during this phase of development.
