title: Instrumented stabilization in spinal tuberculosis.
abstract: Spinal tuberculosis (TB) produces neurological complications and grotesque spinal deformity, which in children increases even with treatment and after achieving healing. Long-standing, severe deformity leads to painful costo-pelvic impingement, respiratory distress, risk of developing late-onset paraplegia and consequent reduction in quality and longevity of life. The treatment objective is to avoid the sequelae of neural complications and achieve the healed status with a near-normal spine. In TB, the spine may become unstable if all three columns are diseased. Pathological fracture/dislocation of a diseased vertebral body may occur secondary to mechanical insult. Surgical decompression adds further instability, as part of the diseased vertebral body is excised. The insertion of a metallic implant is to provide mechanical stability and the use of an implant in tubercular infection is safe. Indications for instrumented stabilisation can be categorised as: (a) pan vertebral disease, in which all three columns are diseased; (b) long-segment disease, in which after surgical decompression a bone graft >5 cm is inserted with instrumentation to prevent graft-related complications and consequent progression of kyphosis and neural complications and (c) when surgical correction of a kyphosis is performed when both anterior decompression and posterior column shortening is required. The implant choice should be individualised according to the case. Pedicle screw fixation in kyphus correction in healed disease is a most suitable implant. Hartshill sublaminar wiring stabilisation in active disease is a suitable implant to stabilise the spine, taking purchase against healthy posterior complex of the vertebral body to save a segment.
