Overview
Classification
Paraplegia as a result of the infection can be classified into early and late paraplegia based on the activity of the tuberculous infection:
Based on the Onset of Paraplegia
Early Paraplegia
- It develops in the active stage of tuberculosis infection, commonly seen in adults within 2years of infection.
- The spinal compression is due to the pressure from the necrotic debris from the damaged bone and intervertebral disc, pus and the granulation tissue.
- Spinal compression in spinal tuberculosis can result from other causes causing compression such as subluxation and dislocation due to destruction of anterior column, compression fracture as a result of wide spread infection, spread of infection to the spinal cord, arterial thrombosis and formation of a intra or extramedullary tuberculoma of the spinal cord.
- Emergent treatment is warranted in patients presenting with early paraplegia.
Late Paraplegia
- It is a complication that develops in a patient with healed tuberculosis. The timing of presentation is variable and can occur 2 or 3 decades after the active infection. Typically it is defined as neurological symptoms appearing after 2years of primary infection.
Stages of Spinal tuberculosis
Stage | Description | Imaging Findings | Duration |
---|---|---|---|
I | Stage of implantation, Incipient stage or
Predestructive stage |
Straightening of the spine
or loss of curve |
< 3 months |
II | Stage of early destruction | Diminished disk space, paradiskal erosion, kyphosis
<10 degrees ( K1) |
2–4 months |
III | Stage of advanced destruction and collapse | 2 or more vertebral involvement with collapse. Kyphosis 11-60 (K3)
or Gibbus > 60 (K3) |
3–9 months |
IV | Stage of neurological involvement | Stage III or IV with 4 grades of paraplegia | Variable |
V | Stage of residual deformity and aftermath | Kyphosis K1, K2, K3, disease active locally grumbling, reactivated or
healed |
3–5 year |
