2. EXAMINATION
Aim of examination is:
• to pick up findings suggestive of TB
• to localise the site of lesion(superficial,deep, rotatory palpation)
• find skip lesions (radiologically)
• to detect any associated complications
Physical general examination - to detect active or healed
primary lesion. The patient may have some other systemic
illness ( diabetes, HTN, jaundice etc)
3. • Gait - Patient walks with short steps in order to avoid jerking
the spine. In TB of cervical spine, the patient often supports
his head with both hands under the chin and twists his whole
body in order to look sideways. In Dorsal Spine TB, Military
attitude is seen.
• Attitude and deformity - Tb of cervical spine patient has a
stiff, straight neck. In dorsal spine TB, part of the spine
becomes prominent (gibbus or kyphus)
4. • Tenderness - Elicited by pressing upon the side of spinous
swelling on — the back, along the chest wall or spinous
process.
• Movement - Limited spinal movements.
• Para-vertebral swelling - A superficial cold abscess may
present
5. • Neurological examination - Thorough neurological
examination of the — limbs, upper or lower, depending on the
site of TB should be performed. In addition to motor, sensory
reflexes examination, an assessment should be made of urinary
or bowel functions.
1. whether or not there is any neurological compression
2. level of neurological compression
3. severity of neurological compression
8. Psoas Abscess
• It is purulent collection within the psoas Muscle, which mostly
spreads through the hematogenous route.
9. •
Early onset paraplegia
(group A)
⚫Appears within 2 years of
onset – during the Active
phase
⚫Underlying pathology
-Inflammatory edema
-TB Granulation tissue
⚫Good prognosis
Late onset paraplegia
(Group B)
⚫Appears more than 2 years of
disease in vertebral column
⚫Underlying pathology –due to
mechanical pressure on cord
⚫Poor prognosis
Classification of TB Paraplegia
11. Clinical features of Pott’s Paraplegia:-
⚫Spontaneous muscle twitching in lower limbs
⚫Clumsiness while walking
⚫Extensor plantar response
⚫Exaggerrated reflexes – Sustained clonus of patella and ankle
⚫Motor affected first – then Sensory
⚫Sense of position and vibration – last to disappear
12. TREATMENT
⚫Conservative plan
⚫Middle path regime
⚫Radical surgery approach
⚫Supportive treatment like
1)rest
2)braces
3)high protein diet
4)Urinary tract care
5) improve immune status
13. •
Bactericidal drugs Dose
Isoniazid 5 mg/kg (300-400mg in single/two
divided doses)
Rifampicin 10-15 mg/kg (450-600mg in
single/two divided doses)
Streptomycin 20 mg/kg ( max 1gm)
Pyrazinamide 40 mg/kg in single/two divided doses
Ethambutol 15-25 mg/kg in single/two divided doses
Bacteriostatic drug Dose
1st line chemotherapy drugs:-
14. Treatment Regime
• Intensive phase- HRZE for 5-6 months
• Continuation phase HR for 9-10 months
• 10mg pyridoxine is given to prevent neurological
deformity
16. Middle Path Regimen
• Rest in hard bed
• Chemotherapy
• X ray and ESR once in 3 months
• MRI/CT at 6 months interval for 2 yrs
• Gradual mobilization is encouraged in absence of neural deficit
with spinal braces and back extension exercises at 3 to 9 weeks
17. • Abscesses- aspirate when near surface and instill 1gm
streptomycin +/- INH in solution
• Excisional surgery for posterior spinal disease
• Operative debridement – if no arrest after 3-6 months of ATT/
with recurrence of disease
• Post op spinal brace- 18 months to 2 years
18. Indication for surgery in patients with
spinal TB & paraplegia
• Absolute Indications –
• Onset of paraplegia during conservative treatment
• Persistent or complete loss of motor power for 1 month despite
conservative treatment
• Paraplegia accompanied by uncontrolled spasticity
• Severe paraplegia of rapid onset
• Paraplegia of flexion
• Flaccid paraplegia
• Complete sensory or motor loss more than 6 months
19. • Relative Indications-
• Recurrent paraplegia
• Paraplegia with onset in old age
• Painful paraplegia
• Complications like UTI and Stones
20. Surgeries for Pott’s Paraplegia
• Antero-Lateral Decompression (M/c) – spine is opened up
from the lateral side and access is made to the front and side of
the cord. The cord is laid free from granulation tissue, caseous
material, bony spur or seqestrum.
• Posterior Decompression
• Costo-Transversectomy- removal of 2 inches of rib and
transverse process -> pus drained
22. • Radical debridement and arthrodesis (Hongkong Operation)
• Laminectomy and posterior stabilisation – indicated in spinal
tumor syndrome and paraplegia resulting from posterior spinal
disease.
23. Spinal Braces
⚫Spinal braces are mostly used forambulation of cases of spinal
tuberculosis.
⚫Commonly used spinal braces for lesions from fourth dorsal to
second lumbarvertebra are jewett(milwaukee) brace, ASHE
(anteriorspinal hyperextension) brace , taylor brace.

Type A –
Abscess
Caseous tissue
Ischaemic lesion of cord (Rare)
Type B - TB Debris
TB Sequestra from body and disc
Localized Internal gibbus
Canal stenosis / Severe kyphotic deformity
Recommended for tuberculous lesions in dorsal if the number vertebra involved is more than 2 or there is panvertebral disease
MORE ACCEptable in young women and girls, as it gets hidden under clothes. It runs from symphysis pubis to manubrium sterni
BECAUSE it leaves the Back , particularly free except the occipital pad.
