Diagnosis:  Burst fracture of C5 with a flexion teardrop-type of mechanism.  Cord contusion with intramedullary hemorrhage, small epidural hematoma, and small herniated nucleus pulposus at C3-4 and C5-6.

The burst fracture seen here involving C5 also has characteristics of a flexion teardrop fracture. Burst fractures are produced by a combination of flexion and axial loading while flexion teardrop fractures involve such severe flexion that the anterior corner (teardrop) is separated from the posterior half of the body, which is displaced into the spinal canal, damaging the cord.  The MR shows clear evidence of this type of mechanism in the disruption of the anterior longitudinal ligament and partial disruption of the posterior longitudinal ligament.

診斷:C5爆裂性骨折伴屈曲淚滴型機制,。脊髓挫傷伴髓內出血，硬膜外小血腫,，C3-4,、C5-6處髓核小疝。圖中C5所示的爆裂骨折也具有屈曲淚滴骨折的特點,。爆裂性骨折是屈曲和軸向載荷共同作用的結果,，而屈曲淚滴骨折屈曲嚴重，導致前角(淚滴)與淚滴體后半部分分離,，而后半部分移位進入椎管,，損傷脊髓。MR明確顯示了這種機制在前縱韌帶斷裂和后縱韌帶部分斷裂中的作用,。
