|Latin||Condylus lateralis femoris|
|Anatomical terms of bone|
The lateral condyle is one of the two projections on the lower extremity of femur. It is the more prominent and is the broader both in its antero-posterior and transverse diameters.
The most common injury to the lateral femoral condyle is an osteochondral fracture combined with a patellar dislocation. The osteochondral fracture occurs on the weight-bearing portion of the lateral condyle. Typically, the condyle will fracture (and the patella may dislocate) as a result of severe impaction from activities such as downhill skiing and parachuting.
Open Reduction & Internal Fixation surgery is typically used to repair an osteochondral fracture. For a Type B1 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 extends to the proximal metaphysis or distal diaphysis.
