This causes the lateral part of the distal femur and the lateral tibial plateau to come into contact, compressing the tibial plateau and causing the tibia to fracture. The name of the injury is because it was described as being caused by the impact of a car bumper on the lateral side of the knee while the foot is planted on the ground, although ...
compression fracture of lateral tibial plateau: forced valgus of knee when struck from side by car bumper: Bumper fracture at TheFreeDictionary.com: Chance fracture: George Quentin Chance: horizontal fracture of vertebral body: hyperflexion of spine, seen in car accidents when lap belts were used: Chance fracture at Wheeless' Textbook of ...
The patella plays no significant role in the posterolateral corner. The bony shape of the posterolateral knee, with the two convex opposing surfaces of the lateral femoral condyle and the lateral tibial plateau, makes this portion of the knee inherently unstable compared to the medial aspect. Thus, it has a much higher risk of not healing ...
Originally described by Dr. Paul Segond in 1879 [6] [7] after a series of cadaveric experiments, the Segond fracture occurs in association with tears of the anterior cruciate ligament (ACL) (75–100%) and injury to the medial meniscus (66–75%), lateral capsular ligament (now known as the Anterolateral ligament, or ALL), as well as injury to the structures behind the knee.
Tibial plateau fracture; Bumper fracture – a fracture of the lateral tibial plateau caused by a forced valgus applied to the knee; Segond fracture – an avulsion fracture of the lateral tibial condyle; Gosselin fracture – a fractures of the tibial plafond into anterior and posterior fragments [16]
The lateral condyle is the lateral portion of the upper extremity of tibia. [1] It serves as the insertion for the biceps femoris muscle (small slip).
Treatment may include physical therapy or, if that fails, surgery. [1] ACS is an emergency, and outcome largely depends on the time to diagnosis and treatment. [12] If treated within 3 hours, the prognosis is favorable. [12] Complications and permanent damage can occur. [13] ACS occurs in about 1-10% of those with a tibial shaft fracture. [6]
The menisci are C-shaped wedges of fibrocartilage located between the tibial plateau and femoral condyles. The menisci contain 70% type I collagen. [11] The larger semilunar medial meniscus is attached more firmly than the loosely fixed, more circular lateral meniscus. The anterior and posterior horns of both menisci are secured to the tibial ...
