|
In the thoracic and lumbar region where does the nerve root exit.
|
Below its corresponding vertebrae so L4 exits between L4 and L5
|
|
|
Which muscle is the primary flexor of the Hip and what is its orgins and insertions
|
Iliopsoas:
O: T12-L5 I: Lesser Trochanter of femur SD: Of Iliopsoas |
|
|
Musles of the Erector Spinae group.
|
S: Spinalis
I: Iliocostalis LO: LOngissmus |
|
|
Facet Trophism:
|
An Asyymetry of the facet joint angles: Usually they are alingled backward and medial in the lumbar spine..in facet trophism they are more alingned in the coronal plane.
|
|
|
Sacralization:
|
Boney deformity Transverse processes of L5 are Long and Articulate with the Sacrum
|
|
|
Lumbarilization:
|
Failure of the fusion of S1 with the rest of the Sacrum
|
|
|
Spina Bifida
|
Anamoly in which there is a defect in the closure of the lamina of the vertebral segment
|
|
|
Spina Bifida Occulta
|
No herniation thru the defect....Only physical sign is a patch of hair ..No nuero defecit
|
|
|
Spina Bifida Meningocele
|
A Herniniation if the meninges.
|
|
|
Spina Bifida MYELOmeningocele
|
Herniation of meninges and nerve root thru the defect..ass. w/ nuero defecits
|
|
|
What is the main motion of the lumbar spine
|
Flexion/Extension
|
|
|
Motion of L5 on the sacrum
|
Sidebending of the L5 will ENGAGE SACRUM TO THE SAME side
ROtation L5 will engage Sacrum to the opposite side |
|
|
Lumbosacral angel/ Ferguson's angle
|
The Lumbosacral angle is caused by the INTERSECTION of a horizontal line and the Line of inclination of the sacrum...
NORMAL LUMBOSACRAL angle 25-35: Increase causes SHEAR stress--> Low back pain |
|
|
Lumbosacral Spine Somatic Dysfunction
|
Pain in low back butt
Ache or muscle spasm S/S:: Increased Pain with prolonges standing.sitting TX: OMT counterstrain/ME/HVLA |
|
|
How does a herniated nucleus pulposus present
|
Due to narrowing of PLL
Herniated disc in lumbar region Disk herniation between L3/L4: Will AFFECT NERVE root of L4 Numbness or tigling down leg, burning/shooting pain S/S weakness decreased reflexes: Dermotomal defecit: + STriaght Leg raising test MRI: BEST REST FOR no More than 2 days. |
|
|
PSOAS SYndrome
|
Flexion/ Contracture of the Iliopsoas: Prolonged position shorten the PSOAS..
Non-Neutral dysfunction of L1/L2..+ SIde shift to contralateral side...Oblique axis and contralateral piriformis spas, + Thomas test Tender pnt. medial 2 ASIS. |
|
|
FLEXION CONTRACTURE of ILIOPSOAS
|
Non-Nuetral DYsfunction of L1 or L2
|
|
|
Describe the path of Spinal Stenosis
|
1.) Hypertrophy of facet joints
2.) Ca2+ Deposits w/ ligamentum flavum and PLL 3.) Loss of Intervertebral disc height. Worse with Extension X-Ray: Osteophytes and decreased Intervertebral disk space present |
|
|
Describe SPondolisthesis
|
Anterior Displacement of 1 vert. in relation to the one below
Occurs @ L4/L5 Due to fatigue fractures of the Pars iNtercularis of the vertebrae S/S: Increased PAIn on Extension: Tight Hamstrings Bilaterally, Stiff legged-waddeling gait.. + Step off sign TX: HVLA iS CONTRAINDICATED, Heal lifts if needed |
|
|
What is the grading of SPONDOLITHESIS
|
Grade 1: 0-25%
Grade 2: 25-50% Grade 3: 50-75% Grade 4: >75% LATERAL X-ray |
|
|
SPONDILOLYSIS
|
Defect of PARS intercularis WITHout ANTERIOR SLIPPAGE
Collar of scotty dog OBLIque X-ray |
|
|
SPONDyLOSIS
|
DEGENERATIVE changes in the intervertebral disk and ankylosing of adjacent vert. bodies
|
|
|
Cuada Equina Syndrome
|
Pressure on nerve roots of the cauda equina massive disk herniation
Low back pain: Sharp SADDLE ANESTHESIA, Decreased DTR, Decreased Rectal Sphinchter tone and LOSS of bowel and bladder control |
