DOI: 10.1177/2309499020908721 Abstract The exact reconstruction of the tibial plateau and articular surface is the main operative aim in the treatment of tibial plateau depression fractures. An excellent example of how detecting a lipohemarthrosis on a horizontal beam lateral knee radiograph can alert the reader to the presence of a radiographically occult intra-articular fracture. Greater axial loading leads to an increased likelihood of bicondylar involvement. This fracture typically happens after a fall or a motor vehicle accident. In particular, the cartilage meniscus and the cruciate ligaments attach there. The ramifications of missing this important fracture can be profound. Low-signal intensity in the tibial plateau corresponds to the site of fracture. Lipohemarthrosis results from an intra-articular fracture with escape of fat and blood from the bone marrow into the joint, and is most frequently seen in the knee, associated with a tibial plateau fracture or distal femoral fracture; rarely a patellar fracture. May palpate crepitus from subcutaneous fracture fragments. Fractures of the tibia can involve the tibial plateau, tibial tubercle, tibial eminence, proximal tibia, tibial shaft, and tibial plafond. The common peroneal nerve crosses the. The femoral and tibial plateau fractures are open with no gross contamination, and there is an ipsilateral Morel-Lavelle lesion of the . not well established. which is the source of the lipohemarthrosis. It is common for CT to be performed to review the extent of the fracture prior to surgery. [1] 2 case question available Case Discussion This case represents a Schatzker type V fracture. A tibial plateau fracture is an injury in which you break your bone and injure the cartilage that covers the top end of your tibia (bottom part of your knee). On the AP projection, increased trabecular density beneath the lateral tibial plateau is abnormal. . xctmri 201105 indications. . The tibial plateau is a critical weight-bearing area located on the upper tibia. Most commonly, lipohemarthroses are produced with minimally displaced fractures of the tibial plateau Since cross-table lateral views of the knee in which the x-ray beam is horizontal are commonly performed in trauma patients, lipohemarthroses are more commonly seen with this joint Three bands can normally be distinguished Distal femur fracture. In this case a significant fracture of the lateral t. ct. Axial bone window. The symptoms of a tibial plateau fracture are: Pain On Bearing Weight.

Type 1 is a split-off fracture of the lateral tibial plateau without compression of the plateau ( 2 ). Lipohemarthrosis indicates either a fracture with intra-articular extension or significant intra-articular soft tissue injury (ligamentous or meniscal). Bedside ultrasound may reveal lipohemarthrosis, suggesting a radiographically occult and subtle tibial plateau fracture. AP, lateral, oblique views (internal for lateral plateau, external for medial plateau). [1] This fracture involves the proximal (upper) portion of the tibia which extends through the articular surface (into the knee joint). Line drawings of Schatzker types IV, V, and VI tibial plateau fractures. Type IV is similar to type I fracture, except that it involves the medial tibial plateau as opposed to the lateral plateau. Line drawings of Schatzker types IV, V, and VI tibial plateau fractures. It is quite a serious injury. Lipohemarthrosis (presence of fat and blood from bone marrow in the joint space after an intraarticular fracture) seen on X-ray in a person with a subtle tibial plateau fracture. A. They can occur in younger individuals who sustain a high energy trauma or, with increasing age, lesser degrees of trauma and underlying bone pathology such as osteoporosis, metabolic bone disease, and malignancy.

RF 2C3N9KK - x-ray image of Right knee AP view showing Total knee arthroplasty and fractures of the tibial plateau with plate and screw fixation. which is the source of the lipohemarthrosis. 3 Outcomes after tibial plateau fractures are predicted primarily by the adequacy of reduction and alignment obtained and associated soft tissue damage. Tibial plateau fractures usually occur due to high-energy trauma, characteristically produced by varus or valgus forces coupled with axial loading. Knee dislocation. 1 Outside these cases, tibial plateau fractures are relatively uncommon. . This finding is more specific for intra-articular fractures than serous joint effusions alone. In this case a significant fracture of the lateral tibial plateau is revealed upon CT evaluation. The presence of a lipohemarthrosis or a simple joint effusion was also noted. For selected cases, a novel technique with the use of balloon tibioplasty in combination of bioabsorbable calcium phosphate cement is available. [1] People are generally unable to walk.

In addition to the cortical irregularity in the medial tibial plateau (the fracture), there is a large joint effusion, best seen on the lateral view. Tibial Plateau Fracture Surgery is required when the bone breaks into two or more fragments and surgery is normally needed. Tibial plateau fractures most often occur in the setting of high-energy injuries as a result of a valgus or varus force on the knee with or without axial loading. Three layers of effusion are demonstrated on this proton density sequence: fat, red blood cells, and serum. Lipohemarthrosis results from an intra-articular fracture with escape of fat and blood from the bone marrow into the joint, and is most frequently seen in the knee, associated with a tibial plateau fracture or distal femoral fracture; rarely a patellar fracture. The joint effusion contains a straight line, representing a fluid-fat level, with the lighter fat from the bone marrow ("lipo") floating above the heavier blood ("heme"). A tibial plateau fracture affects the knee joint, stability and motion. Depending on the view, lipohemarthrosis might be the only clue to a . RF DCG3T8 - Anatomy of human knee joint. They have also been described in hip, shoulder, elbow and wrist fracture --------- A fracture of the upper tibia (shin bone) may result in injury to both the bone and the soft tissues of the knee region.
