Exam of Thoracic & Lumbar Spine Flashcards
What is the medical term for abnormal increased concavity of the thoracic spine?
lordosis
What is the medical term for abnormal increased convexity of the lumbar spine?
kyphosis
What composes mechanics of the back?
vertebrae & IV discs
ligaments
large superficial & deep intrinsic muscles
Bony structures of spine
vertebral body supports weight bearing
posterior vertebral arch encloses the spinal cord
Inspection of spine
assess of erect position of head, neck & back
for smooth, coordinated neck movements
ease of gait
What to pay attention to during inspection
spinous processes (C7 & T1) paravertebral muscles on either side of midline iliac crests posterior superior iliac spine line drawn above PSIS (crosses SP of L4)
Back flexion muscles
psoas major, psoas minor, quadratus lumborum, ab muscles attaching to anterior vertebrae, int & ext obliques
Back extension muscles
deep intrinsic muscles of back (erector spinae & transversospinalis groups)
Back rotation muscles
ab muscles, intrinsic muscles of back
Back lateral bending muscles
ab muscles, intrinsic muscles of back
Spinal column ROM
if any of ROM produces pain or tenderness, w/ radiation into leg, proceed to neuro testing of lower extremities
Palpation of spine
SP of thoracic & lumbar spines
TP of thoracic & lumbar spines
paraspinal muscles of thoracic & lumbar spines
TART findings
Step off
occurs in spondylolisthesis (forward slippage of 1 vertebra) may compress spinal cord
if 1 SP is unusually prominent in relation to 1 above it
Sacroiliitis
tenderness over sacroiliac joints (palpate over PSIS)
Ankylosing spondylitis
tenderness over sacroiliac joints (palpate over PSIS)
