One trial compared the use of a circular fixator combined with insertion of percutaneous screws (hybrid fixation) versus standard open reduction and internal fixation (ORIF) in people with open or closed Schatzker types V or VI tibial plateau fractures. We judged the quality of most of the available evidence to be very low, meaning that we are very uncertain about these results. All six trials were small and at substantial risk of bias. Three trials evaluated different types of fixation and three analysed different types of bone graft substitutes.

Such injuries are primarily seen in women >50 years with osteoporosis resulting in a depressed pattern plateau fracture.We included six trials in the review, with a total of 429 adult participants, the majority of whom were male (63%).

Low-energy forces can cause a tibial plateau fracture usually in older patients with poor bone quality due to rotational forces.

Motor vehicle injuries are high energy and often result in splitting types of fractures as well as direct injury to the surrounding soft tissues.

The bumper of a car striking the lateral plateau during this vehicle–pedestrian-related injury causes a valgus mechanism of injury.

Most tibial plateau fractures result from motor vehicle-related injuries followed by sports-associated injuries.

The causes of most tibial plateau fractures are a valgus stress associated with an axial load.

Proximal tibial injuries can occur due to direct trauma or indirect mechanisms such as axial compression.

The peripheral part is flat and separated from femur by the lateral meniscus.

The central part is slightly concave and comes in direct contact with femoral condyle.

The articular surface is nearly circular.

The lateral condyle overhangs the shaft of tibia.

The peripheral part is flat and separated from femoral condyle by the medial meniscus.The central part of the medial condylar surface is slightly concave.The articular surface of medial condyle is oval and it is long axis is anteroposterior.The medial condyle is larger than the lateral condyle.The medial from the lateral tibial condyle are separated by the intercondylar eminence which serves as the attachment for the anterior cruciate ligament (ACL).The stronger of the two articular surfaces is the medial tibial condyle whereas the lateral tibial condyle is a weaker portion of the joint.The tibial plateau is the proximal portion of the tibia and forms the part of the knee joint.Majority of the weight in the lower leg is transmitted through tibia.Source: Case courtesy of Henry Vandyke Carter As osteocytes grow, viability of cells decrease thereby decreasing the bone mass density.Īnatomy of tibial plateau.

The capability of autophagy in cells decreases as they age, a major factor of aging.Autophagy is the mechanism through which osteocytes evade oxidative stress.Decrease in bone mass density involves following process:.Position of the knee and leg at the time of impact.The fracture pattern and severity of comminution depends on multiple factors including:.Various combinations of these variables lead to a variety of different fracture patterns. 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.
