THORACOLUMBAR Flashcards
True Ribs
Ribs 1-7
False Ribs
Ribs 8-10
Floating Ribs
Ribs 11-12
Caliper Action
11-12 (lateral)
Bucket Handle Rotation
7-10 (forward, backward, and lateral)
Pump Handle Action
1-6 (anteroposterior)
Spondylosis
degenerative changes in the intervertebral disc
Spondylolysis
defect in the pars interarticularis or arch of vertebra
Spondylolisthesis
anterior displacement
Retrolisthesis
backward displacement
Lumbarization
S1 becomes the sixth lumbar vertebrae
Sacralization
L5 fuses with sacrum and coccyx
Lumbar Facet
carries 20-25% of axial loading
T7
greatest spinous process angulation; upper limb rotation alternates with lower limb rotation
Annulus Fibrosus
outer layer; strength and torsional movements
Nucleus Pulposus
85-90% of water; decreases to 65% with age; avascular; slightly posterior
Schmorl’s Nodules
herniations of nucleus pulposus
Disc Protrusion
disc bulges posteriorly without rupture of annulus fibrosus; affects nerve root below
Disc Prolapse
annulus fibrosus contains the nucleus
Disc Extrusion
annulus fibrosus is perforated and disc material flows into the epidural space
Sequestrated Disc
discal fragments form outside the disc proper
Cauda Equina
saddle anesthesia; bladder/ bowel dysfunction
Lifting a 20kg with back bent and knees forward
169% of disc pressure at L3
Walking
15% of disc pressure at L3
Coughing or Straining
5-35% of disc pressure at L3
Bending Forward
150% of disc pressure at L3
Scheuermann’s Disease
13-16 years old
Idiopathic Scoliosis
adolescents
Lumbar Disc Problems
15-40 y/o
Ankylosing Spondylitis
18-45 y/o
male
Spondylosis and OA
> 45 y/o
Malignancy
> 50 y/o
Scoliosis and LBP gender predisposition
females d/t menstruation
(ask: changes in menstruation, altered pain pattern, irregular menstruation, swelling of abdomen and breast)
Pain in thoracic disc lesion
no pain in active movements
Pain in nerve root/ spondylosis of thoracic
“through the chest pain”
Pain in breathing
pulmonary issues; trauma, structural deformities, thoracic pathologies
Pain referred around the chest
costovertebral in origin
Pain on true thoracic ribs
Localized
Constant ache
mechanical, inflammation
Pain on movement
mechanical stimulus
Pain accumulates with activity
repetitive mechanical stress, inflammation, and degenerative disc
Pain increases with sustained posture
fatigue on supporting muscles, gradual creep of tissues
Latent nerve root pain
Movement produces acute and temporary neuropraxia
Facet syndromes
local pain but can also be referred; ROM is same (restricted from the beginning)
Mechanical LBP/ Lumbago
unilateral with no referral to knee (muscle strain/ sprain);
Muscles and Ligaments Affectation
movements will decrease and pain will increase
Bilateral pain
disc injury, central protrusion, spondylolisthesis, spinal stenosis, metastasis
Thoracic Nerve Pain
severe referred in a sloping band along intercostal space
Lumbar Disc Protrusion
pain in back and buttocks
Lumbar and Sacroiliac Pain
back and posterior leg (lateral aspect)
Hip Pain
groin and anterior thigh (medial side of knee)
Pressure on nerve root sheath d/t disc lesion
pain followed by paresthesia
Paresthesia without pain
cord compression, diabetes, pernicious anemia, multiple sclerosis
Upper lumbar/ lower thoracic disc lesions
septic, metabolic disorders, tumors, rheumatic inflammation
Dural Pain
coughing, sneezing, straining on thoracic region
extra segmental and felt at larger areas in the lumbar
Radicular Pain
felt on 1 dermatome in lumbar
Aggravating Movements in Thoracic
active use of arms
pushing and pulling
Costal Pain
overhand arm motions and breathing
Intrathecal Pressure
lumbar spine affectation (neurological tissue)
Disc Pathology
inc in sitting, light twisting, and bending
Relieving Factors in Thoracic
raising or bracing arms facilitates accessory muscles of respiration
Acute Back Pain
3-4 weeks
Subacute Back Pain
up to 12 weeks
Chronic Back Pain
> 3 mos
accompanied by deconditioning syndrome
Predictors of Chronicity within 6-8 weeks of Back Pain (Yellow Flags)
nerve root pain/ spinal pathology
severity of pain during acute phase
beliefs about pain being work related
psychosocial aspects of work
psychological distress
compensation
time off work
longer someone is off work= lower probability to return to work
