Severe Pott's Kyphosis in a 19-Month-Old Child: Case Report and Review of Literature

BACKGROUND: Spinal osseous tuberculosis, or Pott's spine, although very common in endemic countries, has a lower incidence in very young children. However, the infection has the propensity to cause greater vertebral destruction in this age group, leading to severe structural kyphotic deformity and associated neurologic deficits. We report the case of a 19-month-old child with severe tubercular kyphotic deformity of the upper thoracic spine managed with posterior vertebral column resection (VCR) and nonfusion posterior pedicle screw instrumentation. CASE DESCRIPTION: This 19-month-old boy presented with 1-month history of spontaneous-onset, progressive, painful rigid kyphotic deformity of the upper back associated with spastic paraparesis with bowel and bladder incontinence. Magnetic resonance imaging showed severe destruction of bodies of D4-D7 vertebrae with cord edema and draping of the spinal cord over the internal gibbus at D4-D7 Surgery was performed with a restricted anterior fusion via single-stage posterior VCR at D4- D7 with nonfusion pedicle screw instrumentation from D1 to D9, with subsequent extension of instrumentation to D10 after 4 months. CONCLUSIONS: Multilevel posterior VCR with a restricted fusion and non-fusion pedicle screw instrumentation beyond the resection site can be safely done in young children (age <3 years) requiring rigid tubercular kyphotic deformity correction. However, these patients require regular follow-up and may need multiple surgeries.
