  12. Spine Pathology • Trauma • Degenerative disease • Tumors and other masses • Inflammation and infection • Vascular disorders • Congenital anomalies

  13. Trauma

  14. Evaluating Trauma • Fracture – plain film / CT • Dislocation – plain film / CT • Ligamentous injury – MRI • Cord injury – MRI • Nerve root avulsion – MRI

  15. Plain film findings may be very subtle or absent! Anterolisthesis of C6 on C7 (Why??)

  16. CT Fractures of C6 left pedicle and lamina

  17. CT – 2D Reconstructions Acquire images axially… …reconstruct sagittal / coronal

  18. 26M MVA

  19. Vertebral body burst fx with retropulsion into spinal canal 2D Reformats

  20. Vertebral Artery Dissection/Occlusion Secondary to C6 Fracture

  21. Hyperflexion fx with ligamentous disruption and cord contusion

  22. Nerve root avulsion Axial Coronal Sagittal

  23. Degenerative Disease

  24. Degenerative Disc (and Facet Joint) Disease Foraminal stenosis Thickening/Buckling of Ligamentum Flavum

  25. Degenerative Disc (and Facet Joint) Disease

  26. Degenerative Disc (and Facet Joint) Disease

  27. Lumbar Spinal Stenosis

  28. Lumbar Spinal Stenosis

  29. Lumbar Spinal Stenosis

  30. Lumbar Spinal Stenosis

  31. Lumbar Spinal Stenosis

  32. Lumbar Spinal Stenosis Disc bulge, facet hypertrophy and flaval ligament thickening frequently combine to cause central spinal stenosis Note the trefoil shape of stenotic spinal canal

  33. Lumbar Spinal Stenosis Disc bulge, facet hypertrophy and flaval ligament thickening frequently combine to cause central spinal stenosis Note the trefoil shape of stenotic spinal canal

  34. Neural foramen Foraminal Stenosis
