1 Spine Outline Sports Med

2 Anatomy Bones of the Vertebral Column Bones of the Vertebral Column 33 vertebrae 33 vertebrae 24 movable (true) 24 movable (true) 9 immovable (false) 9 immovable (false) Movable Movable Cervical, thoracic, lumbar Cervical, thoracic, lumbar Immovable Immovable Sacrum, coccyx Sacrum, coccyx

3 Cervical Spine 7 Vertebrae 7 Vertebrae C1 Atlas C1 Atlas Supports head Supports head Has no body or spinous process Has no body or spinous process Movements = flexion, extension, lateral movements Movements = flexion, extension, lateral movements C2 Axis C2 Axis Allows rotation Allows rotation

4 Thoracic Spine 12 Vertebrae 12 Vertebrae Articulate with the ribs Articulate with the ribs

5 Lumbar Spine 5 vertebrae 5 vertebrae Major support of the low back Major support of the low back Largest and thickest Largest and thickest

6 Sacrum Coccyx Fusion of 5 vertebrae in adults Fusion of 5 vertebrae in adults Sacroiliac joint Sacroiliac joint While sitting weight is transmitted through these joints While sitting weight is transmitted through these joints Also known as the tailbone Also known as the tailbone

7 Intervertebral Disks Between each of the cervical, thoracic, and lumbar vertebrae lies disks Between each of the cervical, thoracic, and lumbar vertebrae lies disks Each disk is composed of annulus fibrosus and the nucleus pulposus Each disk is composed of annulus fibrosus and the nucleus pulposus Annulus fibrosus Annulus fibrosus Forms the periphery of the disk Forms the periphery of the disk Composed of strong, firbrous tissue Composed of strong, firbrous tissue Nucleus pulposus Nucleus pulposus In the center of the annulus fibrosus In the center of the annulus fibrosus Shock absorption Shock absorption

8 Ligamentous Structures Anterior longitudinal ligament Anterior longitudinal ligament Wide strong band extends the full length of the anterior surface of vertebrae Wide strong band extends the full length of the anterior surface of vertebrae Posterior longitudinal ligament Posterior longitudinal ligament Inside the canal and extends the full length of the posterior aspect Inside the canal and extends the full length of the posterior aspect Supraspinous Supraspinous Connects spinous processes Connects spinous processes

9 Muscles of the Spine Superficial Superficial Erector spinae Erector spinae Extends the spine Extends the spine Deep Deep Go from vertebrae to vertebrae Go from vertebrae to vertebrae Extend and rotate the spine Extend and rotate the spine multifidus multifidus

10 Spinal Nerves and Peripheral Branches 31 pairs of spinal nerves 31 pairs of spinal nerves Each has specific area of sensory called dermatomes Each has specific area of sensory called dermatomes Loss of sensation = nerve damage Loss of sensation = nerve damage Nerves form a plexus Nerves form a plexus

11 Movements of the verterbral column Flexion Flexion Extension Extension Right and left lateral flexion Right and left lateral flexion Rotation to the left and right Rotation to the left and right

12 Preventing Injuries to the Spine Cervical Cervical Can be life threatening Can be life threatening Strengthening is critical Strengthening is critical Bull the neck Bull the neck Isometric, isotonic, isokinetic contractions can be used Isometric, isotonic, isokinetic contractions can be used Watch for spearing Watch for spearing

13 Preventing injuries to the spine Lumbar Lumbar Low back pain is the most common Low back pain is the most common Avoid unnecessary strain Avoid unnecessary strain Be aware of posture anomalies of the athlete Be aware of posture anomalies of the athlete Abdominal strength is essential Abdominal strength is essential
