2 Neck And Spine Sports Medicine Chapter 20

3 Vocabulary  Annulus Fibrosis- periphery of the intervetebral disk, strong fibrosis tissue  Axial Loading -Direct blow to the top of your head  Cervical nerve stretch syndrome- brachial plexus injury  Cyanosis- blue/gray color of the face  Kyphosis-Thoracic curvature of the spine, humpback  Nucleus Pulposus- the inside of the intervetebral disk. Jelly like substance  Paraplegia- paralysis of the lower extremity  Quadriplegia- paralysis of the upper/lower extremities  Sciatica- inflammation of the sciatic nerve in your lumbar spine  Scoliosis- lateral curvature of the spine  Spondylolisthesis- forward slipping of the vertebrae L5 most common  Spondylolysis- stress fracture of the pars interarticuylaris of the vertebrae I knew that word!!

4 Anatomy  Characteristics  33 indiv. Bones or vertebrae  24 moveable  9 immovable  The spine allows for a high degree of flexibility  Cervical  7 vertebrae, first 2 = atlas and axis. Function is to support the head and permit cervical rotation  Thoracic  12 vertebrae. #1-10 articulate with the ribs. Muscles that attach to the thoracic vertebrae= trapezius, rhomboid, latissmus dorsi  Lumbar  5 vertebrae and is considered the largest and strongest  Sacrum  As a child grows up, the bottom 5 vertebrae fuse together. Weight is transmitted through the sacroiliac joint  Coccyx  consist of 4 separate vertebrae which the lower 3 fuse together in adulthood.







11 Brachial Plexus Sensory Muscle movement  C5 lateral upper arm (deltoid) Shoulder abduction (deltoid), elbow flexion (biceps  C6 Lateral forearm 1st/2nd phalange Elbow flexion (biceps), wrist extension  C7 3rd phalange Elbow extension (triceps), wrist flexors, finger extensors  C8 4th/5th phalange, medial forearm Finger flexors, finger abduction/adduction  T1 medial elbow finger abduction/adduction


13 Nerve Roots

14 Injuries to neck  Brachial plexus injury  Nerves that could be involved and should be evaluated:  C5-T1 nerve roots  Peripheral nerves  Radial nerve  Wrist/thumb extension  Dorsal web space between thumb and index finger  Ulnar nerve:  Abduction of 5 th phalange  Distal ulnar aspect of little finger  Median Nerve  Thumb pinch  Distal radial aspect of 2 nd phalange  Axillary nerve  Deltoid movement  Lateral arm silver dollar patch in the middle of the deltoid  Musculocutaneous nerve  Biceps  Lateral forearm

15 Neurological Exam Sensation Testing If there is nerve root compression, sensation can be disrupted

16 Lumbar Plexus Sensory Muscle movement  L3 Distal anterior thigh Knee extension  L4 Patella and medial surface of tibia Dorsi flexion (anterior tibialis)  L5 Top of foot Great toe extension  S1 Lateral surface of foot/5 th metatarsal Ankle Eversion

17 Mechanism of Injury pg 413  An axial load to the top of the head  a flexion force  a hyperextension force  a flexion-rotation force  a hyperextension-rotation force  a lateral flexion force

18 Evaluation of neck and spine injuries.

19 Postural Malalignments

20 Low Back Injuries  History  radiating pain  pain when?  weakness  loss of function  tingling or numbness  check posture  constant pain My aching back

21 Lumbar plexus nerve roots Sensory Muscle movement  L1,2,3,4 Upper to Mid to lower thigh Quadriceps: Knee extension  L4 Medial lower leg Tibialis anterior: Foot dorsiflexion/inversion  L5 Lateral leg and dorsum of foot Extensor hallicus longus: great toe extension  S1 Lateral foot Peroneal longus/brevis: foot eversion

22 Rehabilitation for your low back  Williams low back exercises  Laying down, sitting, driving, standing, lifting, and carrying

23 Injuries  stingers  burners  strains/sprains  fractures  disc problems  spondylolisthesis  spondylolysis  sciatica  scoliosis  kyphosis

24 Injuries to neck  Cervical sprain or whiplash  S/S=  Pain in the neck like a muscle strain but is pt tender over the spinous processes (lig.). Pain may appear the day after the trauma  RX:  Dr., collar, RICE, NSAID’s, contrast therapy and possibly traction  Acute Torticollis (wryneck)  S/S=  Pt tender, muscle spasm, head ROM is limited  Rx:  Contrast therapy, gentle traction, rotation and lateral bending stretching, wear a soft collar possibly, usually lasts for 2-3 days

25 Injuries  Low back strain:  2 causes: sudden extension and trunk rotation  Chronic strain associated with poor posture  S/S= pain in the low back  Rx: ice, ice massage, massage, stretching and rest. Work on good posture

26 Spondylolysis and Spondylolisthesis  Common is activities that cause hyperextension.  Gymnastics, lifting weights, blocking in football, serving in tennis, spike in volleyball, butterfly stroke  S/S= pain over the low back after exercise not during.  Rx: rest and exercises to stabilize the area

27 Lumbar sprains and/or herniated lumbar disc  Mechanism of injury:  bending forward and twisting while lifting.  S/S=  pain is localized but radiates if lumbar disc is herniated down the back of your legs  RX:  RICE to reduce pain, strengthening exercises for abdominals and back extensors. Stretching and good posture need to be preformed daily

28 Low back special evaluation tests  Straight leg raise (SLR)  Used for evaluation of sciatic nerve problem, sacroiliac joint, and lumbar spine  Compression distraction tests  For sacroiliac (SI) joint
