Segond fracture
Segond Fracture
Segond fracture (pronunciation: /səˈɡɒnd ˈfræk.tʃər/) is a type of avulsion fracture in the knee, specifically at the lateral aspect of the tibial plateau. This fracture is typically associated with anterior cruciate ligament (ACL) injuries.
Etymology
The Segond fracture is named after Paul Ferdinand Segond, a French surgeon who first described this type of fracture in 1879.
Description
A Segond fracture is characterized by a small avulsion fracture (typically 1 cm or less) that occurs at the anterolateral aspect of the tibial plateau. This fracture is caused by the forceful pull of the iliotibial band or the anterior oblique band (a ligamentous attachment of the fibular collateral ligament to the mid part of the lateral tibial plateau).
Clinical Significance
A Segond fracture is often indicative of an injury to the ACL. It is seen in up to 75% of ACL injuries and is therefore considered a pathognomonic sign of this type of injury. Other associated injuries can include meniscal tears and other ligamentous injuries.
Diagnosis
Diagnosis of a Segond fracture is typically made through radiographic imaging, such as an X-ray or MRI. The fracture is usually visible on the anteroposterior view of the knee.
Treatment
Treatment of a Segond fracture typically involves addressing the associated ACL injury. This can include surgical reconstruction of the ACL, followed by physical therapy.
