276.Burst fracture of C5(4）

Although there are small disk fragments at C3-4 and C5-6, the cord injury here tells us that this patient probably will not do well even with surgery.  That in fact proved to be the case.  The MR does show a small epidural hematoma, which is not producing any significant compression.  It also delineates the ligamentous injuries well, enabling us to clarify the mechanism of injury, which was not entirely clear from the plain film and CT since the fragments had been reduced to a degree more than that usually seen with flexion teardrop-type injuries.  Note that, while the MR demonstrates vertebral body fractures well, it does not demonstrate the posterior element fractures as nicely as CT, although they are definitely visible .

虽然C3-4和C5-6处有小的椎间盘碎片，但是脊髓损伤告诉我们这个病人即使手术，预后运动功能也不理想。事实证明确实如此。磁共振显示一个小的硬膜外血肿，没有产生任何明显的压迫。它也很好地描述了韧带损伤，使我们能够清楚的了解损伤的机制，这一点在平片和CT上显示的并不清楚，因为这些碎片的减少程度比屈曲泪滴型损伤的常见程度要高。值得注意的是，MR虽然能很好地显示椎体骨折，但不能像CT那样很好地显示后段骨折，尽管它们确实可见。

Notes:

1. epidural [ˌɛpɪˈdʊrəl, -ˈdjʊr-] adj. 硬（脑）膜上的，硬脑膜外的

2. hematoma [ˌhi:mə'toʊmə] n. 血肿
