Stable and unstable fractures A stable pelvic ring injury is usually defined as one that will (theoretically) allow full weightbearing without the risk of pelvic deformity. Of course one cannot actually perform the test in an acutely injured patient.However, because the mechanisms which cause these injuries are fairly consistent, typical patterns and displacements are defined which make it possible to deduce the mechanism of injury, the type of ligament damage and the degree of pelvic instability. Occasionally the decision on stability cannot be made until the patient is examined under anaesthesia. Several classifications are in use. The one presented here is based on that of Young and Burgess (1986; 1987). ---from 《Apley’s System of Orthopaedics and Fractures》 重点词汇整理： consistent /kənˈsɪstənt/adj. 始终如一的，一致的；坚持的 deduce /dɪˈduːs/vt. 推论，推断；演绎出 百度翻译： 稳定和不稳定骨折 稳定的骨盆环损伤通常被定义为（理论上）允许完全负重而无骨盆畸形的损伤。当然，在一个严重受伤的病人身上，我们不能真正地进行测试耐心点。不过由于造成这些损伤的机制是相当一致的，因此定义了典型的模式和位移，从而可以推断损伤的机制、韧带损伤的类型和骨盆不稳定的程度。有时，在病人接受麻醉检查之前，不能做出稳定性的决定。 有几种分类法正在使用中。这里介绍的是基于杨和伯吉斯（1986；1987）的观点。 |
