What type of fracture is associated with an ACL injury?

A Segond fracture is a specific type of fracture that is closely associated with an anterior cruciate ligament (ACL) injury. This fracture is characterized by a small avulsion fracture of the lateral aspect of the tibia, just below the joint line, and it typically occurs due to the mechanism of injury associated with ACL tears. When the ACL is subjected to excessive stress or a sudden twist, it can lead to an avulsion of the bone at the attachment site, resulting in a Segond fracture.

In the context of knee injuries, recognizing a Segond fracture is essential because its presence often indicates a significant ligamentous injury, including the potential for ACL tears. The identification of this type of fracture on imaging studies serves as an important diagnostic clue that guides further management of knee injuries.

Other types of fractures listed, such as patellar fractures, scaphoid fractures, and Colles fractures, do not commonly correlate with ACL injuries and arise from different mechanisms. Each of these fractures involves different anatomical regions and impact mechanisms that do not typically implicate the ACL.
