Overview

The pattern of fracture and degree of comminution are the resultant of several factors or variables such as the nature of injury, the bone quality, the age and weight of the patient, the energy involved, and the position of the knee and leg at the time of impact. Various combinations of these variables lead to a variety of different fracture patterns.

Mechanism of Fracture

  • Proximal tibial injuries can occur due to direct trauma or indirect mechanisms such as axial compression.[5]
  • The causes of most tibial plateau fractures are a valgus stress associated with an axial load.
  • Most tibial plateau fractures result from motor vehicle-related injuries followed by sports-associated injuries.
  • The bumper of a car striking the lateral plateau during this vehicle–pedestrian-related injury causes a valgus mechanism of injury.
  • Motor vehicle injuries are high energy and often result in splitting types of fractures as well as direct injury to the surrounding soft tissues.
  • Low-energy forces can cause a tibial plateau fracture usually in older patients with poor bone quality due to rotational forces.
  • Such injuries are primarily seen in women >50 years with osteoporosis resulting in a depressed pattern plateau fracture.
