Most people have heard of a segond fracture (avulsion fracture of the lateral tibeal platuea) seen on knee xrays which is a marker for Anterior Cruciate Ligament and medial meniscus injuries.
多数人可能知道膝关节X线片所示的Segond骨折（外侧胫骨平台撕脱性骨折），是前交叉韧带和内侧半月板受损的标志。

However, there is also a Reverse Segond Fracture that is another benign appearing avulsion fracture of the medial tibeal plateau that is marker for significant injury to the Posterior Cruciate Ligament (PCL). 
然而也有一种反向Segond骨折，是内侧胫骨平台的良性撕脱骨折，它是后交叉韧带严重受损的标志。

If a Segond or Reverse Segond Fracture is seen consider immobilzing the patients knee until they can follow up with Orthopedics and/or get an MRI to determine if additional injuries are present.
如果出现Segond或反向Segond骨折，建议固定患者膝部直到骨科医生进行治疗以或行MRI以确定是否同时有其他的损伤。
