The Spine
• The functions of the spinal column include:– Supporting the majority of body weight
– Supporting the head, trunk, and UEs against the forces of gravity
– Protection of the spinal cord
– Shock absorption
– Providing a stable structure by which we can maintain an upright posture
Magee, 2008. pg. 92
![Page 3: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/3.jpg)
Spinal Design
• 33 vertical segments, divided into 5 regions:
– Cervical (7)
– Thoracic (12)
– Lumbar (5)
– Sacral (5 - fused)
– Coccygeal (4 - fused)
Dutton, 2012. pg. 259
![Page 4: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/4.jpg)
Spinal Design• 2 functional pillars that assist spine
functionality
• Anterior Pillar: vertebral bodies and
intervertebral disks provide hydraulics,
weight bearing ability and shock-absorption
• Posterior Pillar: consists of articular
processes, facet joints, transverse processes,
and spinous processes. This allows spinal
movement and serves as the attachment for
posterior musculature.
Dutton, 2012. pg. 260
![Page 5: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/5.jpg)

THE INTER-VERTEBRAL DISC
• The inter-vertebral disc
• fibro-cartilagenous tissue
– in between vertebral bodies consisting
• an outer layer (annulus)
• an inner layer (nucleus pulposus)
• The inter-vertebral disc provides:
– Shock absorbtion
– Movement between vertebrae
– Separation between the vertebrae
– To allow passage of nerve roots through the inter-vertebral foramina
Magee, 2008. pg. 516-517
![Page 7: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/7.jpg)
Spinal Mobility
• Flexion:
– Occurs in the sagittal plane
– Anterior portion of the vertebral bodies
approximate and the spinous processes
separate
• Extension:
– Occurs in the sagittal plane
– Anterior portion of the vertebral bodies
separate and the spinous processes
approximate
Dutton, 2012. pg. 262
![Page 8: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/8.jpg)
Spinal Mobility
• Lateral Flexion
– Occurs in the frontal plane
– The vertebral bodies approximate on the side
toward which the spine in bending, and
separate on the opposite side
• Rotation
– Occurs in the transverse pain
– The body of the vertebra will rotate towards the
side in which the person is moving as the
spinous process moves toward the opposite
side
Dutton, 2012. pg. 263
![Page 9: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/9.jpg)
Spinal Mobility
• Shear
– Occurs in sagittal, frontal, and transverse
planes
– When the body of the superior vertebra
translates over the body of the inferior vertebra
• Distraction/Compression
– Occurs in the transverse plane
– Result of longitudinal forces
– Vertebral bodies move either towards or away
from other vertebral bodies
Dutton, 2012. pg. 263

TEST
• The patient is seated on a
plinth with the examiner resting
the palmar surface of his or her
hands on top of the patient’s
head.
• The patient will then laterally
flex the head while the tester
applies a downward pressure.
– This is to be done with lateral
flexion bilaterally

Low Back Pain
Did you know that it is….
• the 2nd leading cause of physician visits in the
United States
• affects approximately 80% of the adult
population at some point in their lives
• one of the leading causes of Physical
Therapy referrals in the orthopedic setting
![Page 51: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/51.jpg)
Some of the primary causes of low back pain
include:
• Muscle Strains
• Ligamentous Sprains
• Disk Injuries
• Spondylolisthesis
• Spinal Stenosis
• Spinal Fractures
![Page 52: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/52.jpg)
The Inter-vertebral Disc
• Health of the intervertebral disc maintains the
health of the integrity of the mechanics of the
spine
• Low back pain may be due to
– Aging
• Reduces the moisture content in the disc
– Reduces overall height
– account for 20-25% of the total length of the
vertebral column
– natural degeneration of the disc
– trauma, inter-vertebral discs can be
responsible for causing low back pain in many
individuals.

A general term used to describe when there is any change in the shape of the annulus
2 Disc protrusion
The nucleus of the disc bulges against an intact annulus
2 Extruded disc
The nucleus of the disc bulges through the annulus however remains within the posterior longitudinal ligament
3 Sequestrated disc The nucleus of the disc breaks
through all barriers and is free within the spinal canal

Inter-vertebral Disc Herniations
Treatment will depend upon– Pain
– Flexibility
– Strength
– Dermatomal and myotomal involvement
– Pain with movement
– Patient understanding
• This may include:
– physical agents
– therapeutic exercise
– therapeutic activity
– strengthening
– flexibility training
– patient education
– body mechanics training
– manual intervention

Surgical Intervention for lumbar disk disease
• Discectomy
– Surgical removal of the herniated disk material
• May also be performed with laminectomy
• Microdiscectomy
– Surgical removal of only the portion of the disk
that is impinging on the spinal nerve root
• Requires decreased recovery time
• Percutaneous discectomy
– Decompression of the disk performed through
needles
Dutton, 2012. pg. 343
![Page 56: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/56.jpg)
The Spine
• Scoliosis
– a lateral curvature of the spine
– usually demonstrated by an abnormal
curve and a second curve that results due
to compensatory movements in the
opposite direction.
• This results in a deformity resembling
the letter S.
Shankman, 2011. pg. 337
![Page 57: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/57.jpg)
The Spine
• Functional scoliosis
– not caused by an actual spinal deformity
• secondary to another condition
– such as leg length discrepancy
• The curvature usually resolves itself
when the primary condition is
addressed.
Dutton, 2012. pg. 307
![Page 58: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/58.jpg)
The Spine
Non-functional (structural) scoliosis
• the opposite of functional scoliosis
• the curvature is incorporated into the natural
growth and development of the spine
• curvature and the vertebral bodies are rotated
toward the convexity.
![Page 59: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/59.jpg)
The Spine
More severe cases of scoliosis
• may require bracing
• to prevent further curvature of the spine from
occurring
– bracing is not intended to correct the curvature
already in place
– prevents further curvature
• minimal correction may occur
Shankman, 2011. pg. 338

The Spine
Lordosis:
• an abnormal anterior
convexity of the
lumbar spine
• Persons with lumbar
lordosis will present
as if they are sticking
out their stomach and
their buttocks.
**Both Kyphosis and
Lordosis can be
congenital,
neuromuscular, or
postural**

Spondylolisthesis
• Congenital
– Results from dysplasia of the 5th lumbar and
sacral arches and zygapophyseal joints
• Isthmic
– Caused by a defect in the pars interarticularis
resulting from an acute or stress fracture or an
elongation of the pars
• Degenerative
– Usually affects older population
– Most common at L4-L5 level
• Traumatic
– Occurs with fracture or dislocation of the
zygapophyseal joint
• Pathologic
– Resulting from a systemic disease causing
weakness of the pars, pedicle, or
zygapophyseal jointDutton, 2012. pg. 346

Spinal Fractures
• Lumbar spinal fractures are usually a result of a traumatic event and may be classified according to the mechanism of injury (compression, flexion, extension, etc…)
• Compression fractures are most commonly noted in the osteoarthritic population as a result of a rapid deceleration when transferring to a seated position.
Shankman, 2011. pg. 330
![Page 73: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/73.jpg)
Spinal Fractures
• Spinal fractures will most likely be
immobilized
– Casting
– Bracing
– until such time that physical therapy
intervention is appropriate

Special Tests for the Lumbar Spine
WELL LEG RAISE TEST:
– the patient lying
supine on a plynth
– the examiner holds
the calcaneous of the
uninvolved leg and
places their superior
hand on the anterior
surface of the
patient’s thigh to
prevent knee flexion
– the examiner
passively flexes the
patient’s hip while
maintaining the knee
in extension
Cook, 2013. pg. 301
![Page 76: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/76.jpg)
Special Tests for the Lumbar Spine
• A positive result for the Well Leg Raise
Test is demonstrated with complaints of
pain on the involved side, indicating
vertebral disk damage.
![Page 77: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/77.jpg)
Special Tests for the Lumbar Spine
SLUMP SIT TEST:– The patient sits at the end of a table with the arms
behind the back and legs together.
– The patient slumps as far as possible, producing full trunk flexion
– If no changes are noted, the examiner asks the patient to extend their knee or passively extends one of the pt’s knees, symptoms are assessed
– If no changes are noted still, the examiner passively dorsiflexes the pt’s ankle with the knee in extension, symptoms are assessed.
– Neck flexion is then added to assess symptoms, then released to see if symptoms subside
– This is to be performed on bilateral LE’s
Cook, 2013. pg. 302
![Page 78: THE SPINE - Mercer County Community College - MCCC - West Windsor, NJ](https://reader031.vdocument.in/reader031/viewer/2022012011/613d39db736caf36b75ad07b/html5/thumbnails/78.jpg)

Special Tests for the Lumbar Spine
VALSALVA’S MANEUVER:
– The patient should sit with the examiner next
to the patient
– The tester asks the patient to hold their
breath and bear down as if having a bowel
movement
• This test is considered positive if
– increase in pain secondary to the increase in
intrathecal pressure.
– May indicate:
• herniated disk, tumor, or osteophyte in the lumbar
cana.
• pain may be localized or referred to a
corresponding dermatome

Special Tests for the Lumbar Spine
• FABER TEST: (also known as the Patrick Test)
– This test is used to determine iliopsoas,
sacroiliac, and/or hip joint abnormalities.
• The patient lies supine on a table
• The examiner passively flexes, ABDucts,
and externally rotates the involved LE until
the foot rests on top of the opposite knee.
• The examiner then provides a gentle,
downward pressure on both the knee of
the painful side and the ASIS of the non-
painful side
