9. Arise frfom ventral root
and gray rami
communicants near DRG
Innervates PLL,ant
dura,post annulus,blood
vessels
ALL,lat & ant annulus –
sympathetics
SP.VIP,CGRP
10. FACET JOINT PAIN
Innervated by medial branches of dorsal primary rami
Facet capsule-contains encapsulated,non encapsulated & free
nerve endings
Mechanoreceptors-inflamation sensitizes these to movements of
facet jt
Nociceptors-unmyelinated & plexiform fibres sensitizes to
chemical or mechanical stimulus
11. mechanism
Injury to articular cartilage as in OA
DEGEN changes of facet jt-static n dynamic compression of
nerve root-lateral recess stenosis
Blockage of facet by synovial fold
18. duration of pain
Acute- strains, sprains
Chronic- degenerative conditions
a/c on chronic
Radiation of pain
Nature of pain
Aggravating/relieving factors
19. Nature and intensity of pain
Discogenic- focal,aching in nature,increased with activity causing
axial loading,decreased with rest
Facetal pain-pain on extension of spine
(Can be of muscle strain)
Degenerative-Pain and stiffness in morning
Inflammatory-prolonged pain with stifness > 1hr
Tumour/infection- Night Pain unrelieved by rest
21. Neurogenic claudication
Diffuse pain n numbness
Progressive loss of walking ability/forward stooping walking
Symptoms produced by activities causing extension of spine,
relieved by flexion
To r/o vascular claudication
23. Occupational history-return to heavy physical work may not
be possible
Family n social history- assess pts resources and support for
treatment plan
Other systems assessment-CVS,PULMO,GI ,GU,ENDO
25. INSPECTION
Gait
Antalgic one leg-nerve root irritation,muscle weakness
Sciatica :walk with hip more extended & knee more flexed
High stepping : foot drop -to clear the ground
Spastic:drags the foot
26. Trendelenburgs : L5 - abductor lurch
S1- extensor lurch
toe walking not possible
L4-heel walking not possible
56. Piriformis syndrome
Entrapment of sciatic nerve by the piriformis as it passes thru the
sciatic notch
Causes:hypertrophy
Trauma
Excessive exercises
Spasm n inflammation
Anomalies of piriformis
Pseudo aneurysm of inf gluteal artery
Traumatic myositis ossifcans
57. Clinical features
History of trauma to SI or gluteal region
Exacerbation of symptoms by lifting leg or
stooping/difficulty in walking
Tenderness over sciatic notch
Sausage shaped mass over piriformis
Felt by rectal exmn-pathognomonic
58. Positive SLR,Lasegue sign
Freiberg sign-pain with forced int rotation of extended thigh
Positive sign of Pace and Nagle-pain with resistance to
abduction n ER the thigh
Tibial nerve is less affected than peroneal
66. Plain Xray
AP
Alignment of vertebral column
Lesion of pedicles/ TP
Side to side collapse
Paravertebral soft tissue shadows
scoliosis
67. Lateral view
Shape n size of vertebralbody
Anterior n posterior walls integrity
Superior n inferior surfaces of body
Wedging
Disc space
Spinal canal-between post end of body n lamina-space
occupied by cord
68. oblique views-for pars defects
Scannograms-to view the entire spinal column
Ct-demonstrates bony lesions better
Mri- demonstrates soft tissues better
Scrrening of whole spine
