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. Stress, which can lead to an avulsion of this kind, almost always occurs during knee flexion and internal tibial rotation, and in most cases only after damage to the primary ACL stabilizer. Examination of 151 ACL ruptures revealed a Ségond fracture in 9% of patients. Nearly all were caused by sports injuries and, understandably, the accident mechanism always included knee flexion and internal rotation of the tibial. In a similarly large number of other knee injuries without damage to the ACL, only one case of a Ségond fracture was found. This phenomenon, which is easy to detect by radiograph, can thus be regarded as a strong indication of the presence of a ligament injury.
胫骨外侧平台撕脱骨折，即外侧关节囊征，越来越多地与前交叉韧带（ACL）断裂相关。这种现象，即Segond骨折，是半月板胫骨韧带的骨性撕脱。可导致这种撕脱的应力几乎总是在膝关节屈曲和胫骨内旋时发生，且在大多数情况下仅在主要的ACL稳定器受损后出现。对151例ACL断裂患者的检查发现，9%的患者存在Segond骨折。几乎所有病例都是由运动损伤引起的，且可以理解的是，事故机制总是包括膝关节屈曲和胫骨内旋。在同样数量的其他未损伤ACL的膝关节损伤中，仅发现1例Segond骨折。这种通过X线片易于检测到的现象，因此可被视为韧带损伤存在的有力指征。
