Q

why sacrotuberous and sacrospinous so important

A

The sacrotuberous and sacrospinous ligaments create the greater sciatic foramen and the lesser sciatic foramen. The largest nerve in the body, the sciatic nerve, passes through the greater sciatic foramen formed by these ligaments. Trauma to these ligaments, and the consequent inflammation, can lead to sciatic nerve pain, which runs down through the leg along the course of the nerve.

standing forward bend
IS dysfunction follow with sacral positionals ilium moving on the sacrum
43
seated forward bend
SI dysfunction follow with sacral positionals sacrum moving on the stabilized ilium
44
straight leg raise
may indicate problems at the sciatic nerve, SIJ, lumbar spine pain at 30: hip or inflammed nerve pain from 30-60: sciatic nerve if df increases pain: nerve room or sciatic nerve irritation (laseague sign) pain between 70-90: SIJ
45
kernig test
pt supine with knee and hip flexed to 90 passively extending knee to elicit pain in the hamstrings back pain may be a sign of nerve root irritation
46
brudzinski sign
supine flexing the neck causes a flex flexion of one or both knees and increase in pain may indicate lumbar disc or nerve root irritation
47
well straight leg raise
supine unaffected leg passively extended into hip flexion produce low back pain can radiate along sciatic nerve nerve root inflammation or disk herniation
48
milgrim test
INSTRUCT: pt supine, raises both of pt's legs 2-3 inches off the table and instructs pt to hold legs off the table for 30 seconds POSITIVE: inability to perform test and/or low back pain INDICATES: weak abdominal muscles or SOL The test increases subarachnoid pressure and is positive when the patient is unable to hold the position for 30 seconds without pain, indicating pathology within or outside the spinal cord sheath, such as a herniated disc
49
hoover test
``` supine cup both calcanei active straight leg raise of one side if cheating/lying, there wont be any downward pressure on the side that isnt being raised malingering ```
50
bowstring test
sciatic nerve irritation affected side is lifted until pain is felt the knee is flexed until pain is relieved at which pressure is applied to popliteal fossa positive indicates a radioculopathy if lowered leg and ad dorsi and neck flexion: nerve root
51
FABERS
flexion, abduction, external rotation supine and figure 4 position may produce pain in the inguinal region indicating a hip pathology overpressure to knee produces pain SIJ
52
FADIR
flexion, adduction, internal rotation supine laying test positive if pt indicates increase in low back pain - lumbar pathology
53
SI compression and distraction
compression or gapping anterior sacroiliac ligaments pt reports posterior gluteal or leg pain test is positive SIJ or sprain
54
knees to chest test
pulling knees to chest bilaterally will increase symptoms in the lumbar spine single knee to check causes pain in the posterolateral thigh= sacrotuberous pain in PSIS when pulling single leg to opposite shoulder= sacroiliac ligament
55
baby cobra
``` press ups extend the spine see if pain radiates into buttocks/thigh which indicates herniated disk if pain localizes or more generalizes be more conservative and perhaps surgical ```
56
reverse straight leg raise
prone lifts affect leg pain in low back= L4 nerve root
57
spring test
Prone position, downward pressure is applied to the spinous process to assess anterior/posterior motion determine hyper/hopemobility of a specific segment
58
prone knee flexion test
athlete prone with knees extended, also prone with knees flexed to 90°; compare lengths by inspecting the heels a. (+) test: short side=posteriorly rotated SI
59
whiplash
symptoms caused by sudden, uncontrolled extension and flexion of the neck, often in a automobile accident or big fall on tailbone
60
wryneck
spasmodic torticollis
61
torticollis
Torticollis is a problem involving the muscles of the neck that causes the head to tilt down. The term comes from two Latin words: tortus, which means twisted, and collum, which means neck. Sometimes it's called “wryneck.” If your baby has the condition at birth, it's called congenital muscular torticollis
62
scheuermanns kyphosis
increase growth in the posterior t/spine as compared to the anterior t/s leading to a wedged vertebrae
63
sciatica
pain that follows the pathway of the sciatic nerve, caused by compression or trauma of the nerve or its root *paul telling us about the wallet in the back pocket
64
herniated lumbar disc
Description: Prolapse of the annulus fibrosis of lumbar disc into spinal canal. S/S: Lower back pain, radicular leg pain such as numbness, pins/needles, and tingling more commonly in one leg than the other. dissipating pain. Most note that sitting is their most uncomfortable position. Standing and lying supine is most comfortable. Physical exam: No back tenderness, straight-leg raise increases radicular pain. Other: L4/5 is most common. Rarely causes cauda equina syndrome Imaging: X-Rays, MRI (w/o contrast) Tx: NSAID, PT, Medrol Dosepak (PO steriods), Epidural steriod injections, surgical (only for neuro involement or cauda equina syndrome)
65
spondylolisthesis/lysis
spondylolisthesis/lysis spondylolisthesis is considered a complication of spondylysis may be some slipping of one vertebrae onto the one below results in hypermobility of a vertebral segment L5-S1 most common (step deformity)
66
spondylosis
degeneration of the vertebrae and a defect in the pars interarticularis (the region between the superior and inferior articulating facet congenital weakness and occurs as stress fracture no symptoms unless disc herniation or sudden traumatic hyperextension begins unilaterally and can extend bilaterally
67
traction
treatment choice for small protrusion of the nucleus pulposus subatmospheric pressure is created which puts nucleus into its original position as well tightening of the longitudinal ligament which also tend to push protrusion back towards its original position
68
pivms
``` passive intervertebral movements done in side lying flexion, extension, SB, Rotation important to go slow will indicate hyper/hypo mobility of a vertebral joint and symmetry ```
69
alar ligament
extends from sides of the dens to lateral margins of foramen magnum resists rotation at c0-2
70
accessory movements of c/spine
rotate to the L R: anterior and inferior L: posterior and inferior to increase stability
71
biconvex joint
atlas and axis on occiput
72
apical ligament
The apical ligament is a small ligament that joins the apex (tip) of the dens of C2 to the anterior margin (basion) of the foramen magnum. It is the weak, fibrous remnant of the notochord and does not contribute significantly to stability.
73
anterior atlantoacxial
strong membrane, fixed, above, to the lower border of the anterior arch of the atlas; below, to the front of the body of the axis. limits extension
74
posterior atlantoaxial
The posterior atlantoaxial ligament is a broad, thin membrane attached, above, to the lower border of the posterior arch of the atlas; below, to the upper edges of the lamina of the axis. It is a continuation of the Ligamentum flavum, and is in relation, behind, with the obliqus capitis inferior muscle limits flexion
