Presentation Transcript

  1. Ch. 24 Spine

  2. Objectives • Describe how the nervous system works. • Describe the peripheral and autonomic nervous systems. • Describe the function of the sympathetic system. • Explain common injuries to the spine. • Describe the management protocols for an athlete with a back injury. • Explain the symptoms of intervertebral disc herniation.

  3. Anatomy • There is a natural curvature to the spine • Sections • Cervical-7 • Thoracic-12 • Lumbar-5 • Sacrum-5 fused • Coccyx-3 or 4 fused

  4. Vertebrae • Bones in the spine are called vertebras • Irregular shaped bone • Different by section • Cervical smaller, lumbar larger • Body • Foramen • Spinous and transverse process

  5. Intervertebral Disc • Located in between each vertebrae • Allows for movement and flexibility in spine • Two parts • Nucleus pulposus • Jelly like part • Annulus fibrosus • Cartilage • Poor blood supply

  6. Abnormal Posture • Forward Head • Kyphosis-excessive roundedness in thoracic spine

  7. Abnormal Posture • Lordosis-excessive forward curve in lumbar spine • Scoliosis-abnormal side to side

  8. Cervical Injuries • Worst injuries occur with neck in flexion • Fracture of cervical vertebrae can cause quadriplegia • Paralysis of all 4 limbs • Should leave football helmets on

  9. Spondylolysis • Spondylolysis: Stress fracture or bone degeneration of the vertebrae • Spondylolisthesis: vertebrae slips onto the bone beneath it

  10. Disc Herniation • Nucleus pulposus seeps through the annulus fibrosus and presses on the spinal cord • Usually in older people • Unilateral leg pain

  11. Back Strain • Usually in erector spinae, latissimusdorsi, or trapezius muscles • Can be overuse or acute • RICE • E-stim • stretching

  12. Williams Flexion • Pelvic Tilt • Single knee to chest • Double knee to chest • Partial sit up • Hamstring stretch • Hip flexor stretch • Squat

  13. McKenzie Extension • Prone lying • Prone lying on elbows • Prone Press-Ups • Progressive extension with pillows • Standing extension
