Recently, there has been an emphasis placed on incorporating fundamental radiology in graduate level physical therapy curricula; however, the majority of practicing physical therapists never received formal radiology instruction. As health care changes, so must the role of the physical therapist. In a managed care environment, it is essential that physical therapists recognize basic radiographic findings and understand their clinical ramifications. The purpose of this article is to review the literature and provide commentary on avulsion fractures of the lateral tibial condyle, known as Segond fractures. Segond fractures typically occur by forced internal tibial rotation with the knee flexed. This mechanism placed tremendous force on the middle portion of the lateral capsule and associated meniscotibial ligament and results in a small bony avulsion. The Segond fracture is an important radiographic sign that is critical to recognize because it is generally associated with anterior cruciate ligament disruption.
最近，人们开始重视将基础放射学纳入研究生阶段的物理治疗课程；然而，大多数执业物理治疗师从未接受过正规的放射学指导。随着医疗保健的变化，物理治疗师的角色也必须随之改变。在管理式医疗环境中，物理治疗师认识基本的影像学表现并理解其临床意义至关重要。本文的目的是回顾相关文献，并对外侧胫骨髁撕脱骨折（即Segond骨折）进行评述。Segond骨折通常在膝关节屈曲时因胫骨被迫内旋而发生。这种机制会在外侧关节囊中部及相关的半月板胫骨韧带处施加巨大力量，导致小的骨撕脱。Segond骨折是一个重要的影像学征象，必须予以识别，因为它通常与前交叉韧带断裂相关。
