Function of the anterior column vs the posterior column in the lumbar spine

Anterior: weightbearing

Posterior: guiding motion

200

Orientation of cervical, thoracic and lumbar facets

C: 45 degrees

T: 60 degrees

L: 90 degrees

300

Anterior innominate rotation: what does the short arm and long arm of the innominate do?

Short arm glides inferior on short arm of sacrum

Long arm glides posterior on long arm of sacrum

400

Pubococcygeus: Origin, insertion and actions

O: posterior surface of pubis and anterior obturator fascia

I: coccyx and distal sacrum

A: supports pelvic viscera, sacral counternutation

Do some math:

BW: 100 lbs, Sacral angle: 30 degrees

What is the normal force and anterior shear?

Normal force: 100 lbsxcos(30) = 86.6 lbs

Anterior shear: 100 lbs x sin(30) = 50 lbs

Explain the difference between SLR and crossed SLR, then what is normal, referred, HS or neurodynamic findings with SLR

Crossed SLR: doing SLR on the opposite leg and then having symptoms on the untested side, HNP finding

30-70 degrees: neurodynamic or HS (differentiate with head movement)

above 70: likely referred

0-30: should feel nothing
