Scoliosis, Vertebral body scalloping, Fibrous dysplasia, Tibial Pseudoarthrosis, Sphenoid bone deformity, Mental impairment, seizures, hearing loss, exopht halmosis, decreased visual acuity, and GI bleeding eventually occur
When a patient is standing an inclination or listing to one side or the other may be a sign of a possible \_\_\_\_ \_\_\_\_, secondary to a\_\_\_\_\_ \_\_\_\_
sciatic scoliosis, herniated disc
sharp kyphosis in the lower thoracics, affecting the normal lordosis of the lumbar spine
gibbus deformity
palpable or visible step-off from onenprocess to another maybe indicative of a
spondyloslisthesis
anterior or posterior displacement
of a vertebrae with pars defect indicates
spondylolysis (oblique views)

_____ lies at the L3-L4 disc
space at the point where the _____ divides into the common iliacs.
umbilicus, aorta
the primary function of the _______ _____ is to protect the motion segment from anterior shear forces, excessive rotation, and flexion
zygapophyseal joint
Connects two consecutive laminae
Ligamentum flavum
Connects two consecutive spinal processes
Interspinous ligament
Connects the tips of two adjacent spinous processes
Supraspinous Ligament
Functions to restrain flexion, extension, axial rotation, and side bending of L-5 on S-1
Iliolumbar Ligament
separates paravertebral
compartments, and do not have any
mechanical function
intertransverse, transforaminal, and mamillo-accessory (resemble the membranous part of the fascial system)
lumbar spine stabilizer for breathing
Quadratus Lumborum
provide segmental stiffness and control motion
Lumbar multifidus (LM)
Assists the in transmission of extension forces during lifting activities
Thoracolumbar
fascia
Stabilizes the spine against anterior shear and flexion moments
Thoracolumbar
fascia (TLF)
takes origin from the anterior portion of the T12- L5 vertebral bodies and discs- the main hip flexor
Psoas
Pain from a ____
abscess increases
when the hip is
actively flexed
psoas
gives off branches to the hamstrings and then divides into 2 terminal branches – the tibial and the peroneal divisions
sciatic
A disc pathology or a space- occupying lesion can cause the \_\_\_\_ nerve to be tender to palpate
sciatic
To palpate the sciatic nerve –
locate midpoint
between the ____ ____ and the
_____ ____
ischial tuberosity, greater trochanter
A disc is named
after the vertebrae
_____
above
A disc pathology
affects the nerve
root ____
below
little pieces of the
nucleus pulposus protrude into the annular
fibers (weaken annular fibers)
Protrusion
nucleus pops out of the annular fibers NOT yet torn fibers , just stretched
Prolapse aka Bulge
fibers torn,
nucleus bursts into the PLL –
PLL is torn, patient
often describes a shredding noise
Extrusion aka Herniation
multiple pieces of the
nucleus (particles) are in the spinal canal
Sequestration –
_______ joints are innervated by the medial branches of the dorsal rami
zygapophyseal
lateral aspect of IVDs are innervated by
sympathetic innervation
posterior-lateral aspect, outer half of the IVD
sinuvertebral nerve and the grey rami communicants
____ degrees of freedom are available at
the lumbar spine
Six right and left Sagittal (flexion and extension) • Coronal (side bending) • Transverse (rotation)

13°, 5 degrees
•Although ____ alignment provides some
valuable information, a positive correlation
has not been made between _____
alignment and pain

quality, quantity
The key muscle tests examine the integrity of the

isometric tests, the contraction should be

repeated ______ to assess for fatiguability, which could indicate spinal nerve root
compression.

Acute phase goals
• Decrease pain, inflammation, and muscle
spasm
• Promote healing of tissues
• Increase pain-free range of segmental motion
• Regain soft tissue extensibility
• Regain neuromuscular control
• Allow progression to the functional stage
functional phase goals
• Correction of imbalances of strength and
flexibility
• Incorporate neuromuscular re-education
• Strengthening of entire kinetic chain
• Postural correction and retraining
• To initiate and execute functional activities
without pain and while dynamically stabilizing
the spine in an automatic manner
