The Spine
Chapter 25
Anatomy of the Spine
Bones of the vertebral column
• Cervical (7), thoracic (12), lumbar (5), sacral (5
fused), coccyx (4+ fused)
– Intervertebral Disks - shock absorbers
• Ligamentous Structures (anterior and posterior
longitudinal and supraspinous)
Muscles of the Spine (superficial and deep)
• Erector spinae muscle group: superficial portion
• Interspinalis, multifidus, rotatores, and
semispinalis : Deep portion
Spinal Cord, Nerves and Peripheral Branches
1. Disc
2. Body
3. Dura mater
4. Epidural
space
5. Spinal cord
6. Subarchnoid
space
Preventing Injuries to the Spine
Cervical Spine
• Strengthening – protect by resisting excessive
motion
• Range of Motion – flexibility
• Using correct techniques
Lumbar Spine
• Avoid Stresses – completing ADLs properly
• Correct Biomechanical Abnormalities – strength
and flexibility in the core
• Correct techniques when lifting
Assessment of the Spine
History “very important” – R/O cord injury
Observation
• posture and movement evaluation
– Fatback: decrease lumbar curve with increase pelvic
– Swayback:hip exten. at hip, flex of thoracic on lumbar
spine; lumbar in lordosis, thoracic in kyphosis
– Lordosis:increase in lumbar curve
– Scoliosis: lateral curvature of spine
– Kyphosis: increase in thoracic curve
– proximal to distal; muscles
and bony prominence
Special Tests
• stress tests
• Range of Motion
Neurological Exam
• reflex
Palpation
Injuries to the Spine
Cervical Sprain (whiplash) –cervical sprain
• Etiology:sudden snap of the head
• Signs and Symptoms: similar to sprain but last
longer
• Management: Referral to r/o fracture an
neurological problems; collar, RICE, NSAIDs, etc
Spine Injuries
Acute Toticollis (Wryneck)
• Etiology: cold draft of air or head in unusual position for
extended period of time
• Signs and Symptoms:point tender, muscle spasm
• Management: r/o more serious injury; break pain spasm cycle
Cervical Cord and Nerve Root Injuries
• Etiology
–
–
–
–
Laceration : dislocation or fracture
Hemorrhage: dislocation, fx, sprain and strains
Contusion: violent force to neck that does not cause dislocation
Spinal Shock: severe twist or snap; transient signs of spinal cord
injury
• Signs and Symptoms: paralysis, motor and sensory systems
affected
• Management
Injuries to the Spine
Brachial Plexus Neurapraxia (Burner)
• Etiology: stretch or compression of brachial plexus
• Signs and Symptoms: burning sensation, numbness, tingling,
weakness
• Management: once symptoms resolve, athlete can return
Cervical Spine Stenosis
• Etiology: narrowing of spinal canal; congential or developed
• Signs and Symptoms: transient quadriplegia; persistent
burners; weakness
• Management: referral for diagnosis; advise to D/C
participation
Injuries to the Spine
Mechanisms
• Congenital: spondylolisthesis (forward subluxation
of 5th vertebrae); abnormal bony structure )length,
width of vertebrae), etc
• Idiopathic (mechanical or traumatic)
– Mechanical: faulty posture, bad mechanics
– Back Trauma: injuries occuring in competition; WATCH
OUT FOR MIS-MANAGEMENT
– Recurrent or chronic low back pain: malalignment, nerve
rot compressions, muscle weakness
Injuries to the Spine
Herniated Lumbar Disk: usually L4-L5 or L5-S1
• Etiology: forward bending and twisting
• Signs and Symptoms:Radiating pain unilaterally
• Management: pain control; if persists, surgery may be
indicated
Spondylolysis (degeneration of vertebrae) and
Spondylolisthesis (slipping of the vertebral disk)
• Etiology: hyperextension, direct blow, sudden twist
• Signs and Symptoms: aching pain, change positions often,
possibly some neurological symptoms
• Management: bracing, rest, rehab focuses on trunk
strengthening
Injuries to the Spine
Coccyx Injuries: sprain, subluxations, fractures
• Etiology: direct impact
• Signs and Symptoms: refer for x-ray, pain
• Management: ring seat, analgesics
Sacroiliac Joint Dysfunction(sprain, inflammation,
hypermobility, hypomobility)
• Etiology: twisting, falling, landing heavy on one leg, etc
• Signs and Symptoms: tenderness over site, guarding, pain,
ASIS or PSIS asymmetrical
• Management: manage pain, mobilizations, exercises to
strengthen and re-align
Rehabilitation Principles for the
Spine
Joint Mobilization (decrease pain, increase mobility,
increase ROM)
Flexibility Exercises
Strengthening Exercises
Techniques for the Low Back
•

•
•
•
Pain Control (mobs, traction, modalities, etc)
General Body Conditioning
Joint Mobilization Traction
Flexibility Exercises
