Spine Flashcards
Spine - 3 Key Function
Protect cord and Nerves Structural Support for Body, Permit Standing Enable Easy and Flexible Movements
Five Regions of Spine
Cervical - 7 - arms, neck, upper trunk - nerves exit above Thoracic - 12 - trunk, abs - nerves exit below Lumbar - 5 - legs Sacrum - 5 Fused - bladder, bowel, sex organs Coccyx - 4 Fused
Vertebre Anatomy Pedicle, Transverse Process, Lamina, Spinous Process, Vertebral Foramen
Vertebre Anatomy
Facets and Lamina
Facets - Flexible joints connecting vertebra Lamina - Flat Plates create outer wall of vertebral canal
Spine Anatomy Spinal Cord, Dura, Pedicle, Facet Joint, Vertebra, Intervertebral Disk, Nerve Root
Spine Anatomy
Point at which spinal cord ends? Bundle of nerves that continues?
Conus Medullaris Cauda equina
Bones in spine? How many have invertebratal disks?
33 Vertebra 24 seperated by disks
Conditions leading to spine surgery (4)
Herniated Nucleus Pulposus Spondylosis Sentosis Spondylolisthesis
Herniated Nucleus Pulposus
Herniated Nucleus Pulposus - disk degen, inner core leak
Spondylosis
Spondylosis - degen process, caused by OA, DDD, spine stenosis
Sentosis
Sentosis - Cavity narrows compressing cord
Spondylolisthesis
Spondylolisthesis - defect in spine causes vertebra to slip, two types: Degenerative - joint weakens Isthmic - vertebra fractures
Foreman
Opens for spinal nerves to exit
Spine Discectomy, Laminectomy
Disc - bone and disc material removed Laminectomy - Spinous Process and Lamina removed
ACDF
Anterior Cervical Discectomy and Fusion
