Segond fracture | Radiology Reference Article - Radiopaedia.org
2024年4月20日 · Segond fracture is an avulsion fracture of the knee that involves the lateral aspect of the tibial plateau and is very frequently (~75% of cases) associated with disruption of the anterior cruciate ligament (ACL). On the frontal knee radiograph, it may be referred to as the lateral capsular sign.
Lateral Capsular Sign - gentili.net
Lateral Capsular Sign: Frontal radiographs of the knee which reveal a small fleck of bone adjacent to the lateral aspect of the lateral tibial plateau. This "lateral capsular sign" is a simple radiographic finding visible on the routine AP knee x-ray, which indicates severe lateral capsular injury and should alert the examiner to the ...
2018年2月2日 · Segond fractures typically occur by forced internal tibial rotation with the knee flexed. This mechanism places tremendous force on the middle portion of the lateral capsule and associated meniscotibial ligament and results in a small bony avulsion.

2024年11月15日 · The lateral capsular sign, also known as segond fracture, best seen on anteroposterior knee radiographs, is suggestive of severe lateral capsular ligament injury and is highly associated with anterior cruciate ligament tear. It may also be associated with medial and lateral meniscal tears.
Lateral tibial avulsion fractures and disruptions to the anterior ...
Avulsion fractures of the lateral tibial plateau, known as the lateral capsular sign, are increasingly associated with anterior cruciate ligament (ACL) ruptures. This phenomenon, known as the Ségond fracture, is a bony avulsion of the menisco-tibial ligament.
Lateral capsular sign: x-ray clue to a significant knee instability
A simple radiographic finding is described, visible on the routine anteroposterior knee x-ray, which indicates severe lateral capsular injury and should alert the examiner to the high probability of anterior cruciate and medial ligamentous damage.
Segond Fracture - The Emergency Physio
The Segond fracture (or lateral capsular sign) is an avulsion fragment of the lateral tibial plateau, which corresponds to the distal insertion point of the lateral capsular ligament or lateral meniscotibial ligament.
