The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement.It originates from the lateral edge of the medial femoral condyle and the roof of the intercondyle notch [5] then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface.
On the posterior surface of the condyle the linea aspera (a ridge with two lips: medial and lateral; running down the posterior shaft of the femur) turns into the medial and lateral supracondylar ridges, respectively. The outermost protrusion on the medial surface of the medial condyle is referred to as the "medial epicondyle" and can be ...
Anterior-posterior (AP) and lateral radiographs are typically obtained. [4] In order to rule out other injuries, hip, pelvis, and knee radiographs are also obtained. [5] The hip radiograph is of particular importance, because femoral neck fractures can lead to osteonecrosis of the femoral head. [4]
Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). [2] As with any injury , an understanding of the anatomy and functional interactions of the posterolateral corner is important to diagnosing and treating the injury.
Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
A traction splint most commonly refers to a splinting device that uses straps attaching over the pelvis or hip as an anchor, a metal rod(s) to mimic normal bone stability and limb length, and a mechanical device to apply traction (used in an attempt to reduce pain, realign the limb, and minimize vascular and neurological complication) to the limb.
The linea aspera is a prominent longitudinal ridge or crest, on the middle third of the bone, presenting a medial and a lateral lip, and a narrow rough, intermediate line. It is an important insertion point for the adductors and the lateral and medial intermuscular septa that divides the thigh into three compartments .
Open reduction and internal fixation surgery is typically used to repair an osteochondral fracture. For a AO Type B1 [2] [circular reference] partial articular fracture of the lateral condyle, interfragmentary lag screws are used to secure the bone back together. Supplementation of buttress screws or a buttress plate is used if the fracture ...
