![]() ![]() Some fractures may not be seen on plain X-rays. Diagnosis is typically suspected based on symptoms and confirmed with X-rays and a CT scan. Risk factors include osteoporosis and certain sports such as skiing. The cause is typically trauma such as a fall or motor vehicle collision. Complication may include injury to the artery or nerve, arthritis, and compartment syndrome. ![]() Symptoms include pain, swelling, and a decreased ability to move the knee. Patella fracture, fibular fracture, anterior cruciate ligament injury Ī tibial plateau fracture is a break of the upper part of the tibia (shinbone) that involves the knee joint. Suspected based on symptoms, confirmed with X-rays and CT scan Injury to the artery or nerve, compartment syndrome Pain, swelling, decreased ability to move the knee Often these types of fractures are accompanied by extensive soft tissue injuries and risk of compartment syndrome ( a painful condition where pressure within the muscles builds to dangerous levels).Medical condition Tibial plateau fractureĪ severe tibial plateau fracture with an associated fibular head fracture This is a high energy injury involving complex varus and valgus forces. Type VI - Plateau and metaphyseal-diaphyseal dissociation: The main feature of this type of fracture is a transverse subcondylar fracture with dissociation of the metaphysis from the diaphysis.Generally a small amount of metaphyis remains attached to the joint. May also include damage or injury to the anterior cruciate ligament and collateral ligaments. It is usually the result of a high energy injury with a pure axial load. Type V - Bicondylar: These fractures consist of a split fracture of the medial and lateral tibial plateau.May represent a reduced knee fracture-dislocation and subsequent ligament injuries are common. Most commonly associated with neurovascular injury. It is usually the result of a high energy injury and involves a varus force (pushing the knee outwards) with axial loading at the knee. Type IV – Medial plateau: This is a medial tibial plateau fracture with a split or depressed component.This classification of fracture is extremely rare and can result in joint instability. This is a low energy injury typically a result of osteoporotic changes in bone. Central depressions are more stable than lateral or posterior. Type III - Depression lateral plateau: This is a pure compression fracture of the lateral or central tibial plateau in which the articular surface of the tibial plateau is depressed.This is the most common classification of tibial plateau fracture. This is a low energy injury typically a result of osteoporotic changes in bone and occurs most commonly in older patients. Caused by a valgus force (pushing the knee inwards) on an axially loaded limb. Type II - Split depression lateral plateau: This is a combined cleavage and compression fracture and involves vertical split of the lateral condyle combined with depression of the adjacent load bearing part of the condyle. It is common to have a lateral tear to the meniscus. May be caused by a valgus (force pushing the knee inwards) combined with axial loading. It is usually the result of a low energy injury in young individuals with normal bone mineralisation. Type I- Split lateral plateau: This is a wedge-shaped pure cleavage fracture and involves a vertical split of the lateral tibial plateau.The severity correlates with the amount of energy and impact applied to the bone at the time of injury. Each increasing numeric fracture type denotes increasing severity. It consists of six condyle fracture types classified by fracture pattern and fragment anatomy. Multiple tibial plateau fracture classification systems have been developed but the most widely accepted and used system is the Schatzker Classification System. Classification of Tibial Plateau FracturesĪ tibial plateau fracture classification system was developed in order to assess the degree of injury and the appropriate treatment for each type of fracture. ![]()
