3. Introduction
ā¢ TB spine is an infection of the spine caused by M. tuberculosis resulting in
spondylodiscitis, abscess formation, and mechanical instability of the spine.
ā¢ Pottās paraplegia ā paraplegia resulting from tuberculosis of the spine
ā¢ Oldest disease Known to man yet still of public health importance
ā¢ Frequently encountered extrapulmonary form of tuberculosis.
ā¢ Early diagnosis and prompt treatment are necessary to prevent permanent neurological
disability and to minimize spinal deformity.
4. Introduction
ā¢ Found in Egyptian mummies dating back to 3400 BC
ā¢ Percival Pott in 1779 presented the classic description of spinal
tuberculosis.
ā¢ Robert Koch 1882 discovered Mycobacterium tuberculosis
5. Epidemiology
ā¢ Global TB burden
ā¢ 8-10 million new cases per year worldwide
ā¢ Over one million deaths annually
ā¢ The highest incidence occurs in Sub-Saharan Africa and south-east
Asia
ā¢ The highest prevalence is in the Indian sub-continent
ā¢ In endemic countries TB Spine
ā¢ Common in children and young adults
ā¢ Common cause of nontraumatic paraplegia
ā¢ Equally affects males and females
6. Epidemiology
ā¢ 10% of Extra Pulmonary TB have skeletal involvement
ā¢ TB spine accounts for 50% of TB of the MSS
ā¢ 1-2% of all cases of TB
7. Risk factors
ā¢ Immune-deficiency states
ā¢ Overcrowding
ā¢ low socioeconomic status
ā¢ Significant exposure to active TB patients
ā¢ High risk occupations such as healthcare workers
10. PATHOLOGY
ā¢ A secondary form of TB
ā¢ AETIOLOGY; Caused mainly by M. tuberculosis and occasionally by M. bovis,
M. africanum, M. microti
ā¢ M. Tb is an acid-fast bacillus, non-flagellated obligate aerobe.
ā¢ Weakly Gram +ve.
ā¢ Stained with Zehl-Neilson stain, cultured on Lowenstein-Jensen medium.
ā¢ No toxin or biofilm
ā¢ Caseous granuloma
ā¢ Spread is chiefly hematogenous
ā¢ Blood supply favors bony involvement on each side of the bone sparing the
disc in adults
11. Pathology
Focus of infection (primary site) lungs, Lymph node
Route of infection: hematogenous spread (paravertebral venous
plexus of Bateson).
Infection begins in the metaphysis of vertebral body
Advances and destroys the cortex, intervertebral disc and
adjacent vertebrae
Infectious exudate may spread beneath the anterior longitudinal
ligament to neighboring vertebrae
12. Pathology
ā¢ Tissue necrosis and breakdown of inflammatory cells result in a paraspinal
abscess.
ā¢ The pus may be localized, or it may track along tissue planes.
ā¢ Progressive necrosis of bone leads to a kyphotic deformity.
ā¢ Typically, the infection begins in the anterior aspect of the vertebral body adjacent
to the disk.
ā¢ The infection then spreads to the adjacent vertebral bodies under the longitudinal
ligaments.
ā¢ Noncontiguous (skip) lesions are also seen occasionally
14. Types of Lesion
1. Paradiscal (commonest)
2. Central
3. Anterior
4. Appendicular
5. Articular(synovial)
15. Lesion
ā¢ Paradiscal
ā¢ Commonest
ā¢ Spread is via arteries
ā¢ Adjacent to intervertebral disc space
ā¢ Subsequent destruction of
subchondral bone
ā¢ Disc space is reduced
ā¢ Central type
ā¢ Spread is via Batson plexus of veins
ā¢ The lesion is in the central portion of
the body and extends centrifugally to
involve the whole body of the
vertebrae
ā¢ Body yields under gravity and muscle
action to compression and collapse
ā¢ Disc space intact
16. Lesion
ā¢ Anterior
ā¢ Destruction of the cortical bone
with spread to the subperiosteal
and sub-ligamentous plane
ā¢ Stripping of periosteum with
Subsequent ischemia with
resultant vertebral body collapse
ā¢ Appendicular(uncommon)
ā¢ The pedicle and lamina of the
vertebrae are primarily affected
ā¢ Spread is via the posterior external
venous plexus
ā¢ Involves posterior arch without
the involvement of vertebral body
17. Pathological sequelae.
ā¢ Paravertebral abscesses e.g. cold abscess in the neck,Psoas,lumbar
abscesses
ā¢ Gibbus , kyphosis
ā¢ Paraplegia: the most serious complication
ā¢ Tuberculous meningitis-rupture of abscess into dura-pachymeningitis;
arachnoiditis= paralysis

59. Surgical Approaches
ā¢ For spinal TB in the cervical spine, an anterior approach is most
common.
ā¢ For the thoracic spine:
ā¢ anterior and anterolateral decompression by thoracoabdominal approach
ā¢ posteriorly there is costo-transversectomy
ā¢ lumbar level spinal TB:
ā¢ Posterior
ā¢ anterior
ā¢ antero-lateral
61. Posterior approach
ā¢ Commonly used approach
ā¢ The ability to achieve adequate exposure for circumferential
spinal cord decompression, and better deformity control through
pedicle screws
ā¢ Possibility of extension of instrumentation
ā¢ Avoidance of thoracotomy-related complications
ā¢ Transpedicular decompression and posterior instrumentation
facilitates faster recovery and also prevents deformity
progression and neurological sequelae in early disease
62. Combined approaches
Indications
ā¢ Osteoporotic bones,
ā¢ Multiple vertebral body involvement
ā¢ Severe kyphotic deformities.
ā¢ severe destructive lesions and junctional pathologies that are inherently unstable
ā¢ Posterior instrumentation with anterior decompression and fusion can be
performed in 1 or 2 stages.
ā¢ Anterior debridement removes infected foci and allows for direct neural
decompression and rigid anterior reconstruction.
ā¢ Posterior instrumentation enables better deformity correction and reduces the
stress on grafts placed anteriorly, thus helping in maintaining sagittal deformity
correction.
ā¢ it is associated with high morbidities
63. INDICATION FOR INSTRUMENTATION
ā¢ Pan vertebral disease: Instrumentation should be done to prevent
subluxation /dislocation of the spine.
ā¢ Long segment disease: Disease of 4 or more vertebral bodies.
ā¢ In the lumbar & cervical spine: There are no costotransverse &
costovertebral articulations as in the dorsal spine.
ā¢ When kyphosis correction is done
ā¢ Injunctional areas such as the CD spine and DL spine
64. Treatment: Surgery
ā¢ Surgery: Abscess drainage
ā¢ Indication

Editor's Notes
Our definition for close contact included either high exposure rates (>15 hours) in 1 or more weeks or high total exposure (>180 hours) during the index patientās infectious period.
Chest xray has a sensitivity of 96% and low specificity of 46% for diagnosis of pulmonary TB
MDR-TB is resistance to Rifampicin and INH
XDR-TB(Extensively Drug āResistance TB ) is defined as resistance to INH and Rifampicin along with resistance to any flouroquinolone and at least one injectable second-line drug.
