The natural history of Pott's kyphosis is different from that of other spinal deformities. After healing of the spinal infection, the post-tubercular kyphosis in adults is static but in children variable progression of the kyphosis is seen. The changes occurring in the spine of children, after the healing of the tubercular lesion, are more significant than the changes that occur during the active stage of infection. ⋯ Dislocation of facets at more than two levels can lead to the "Buckling collapse" of the spine, which is characteristically seen only in severe tubercular kyphosis in children. Age below 10 years, vertebral body loss of more than 1-1.5 pre-treatment deformity angle of greater than 30° and involvement of cervicothoracic or thoracolumbar junction are the other risk factors for deformity progression. In children, the kyphosis can progress even after healing of the spinal infection and hence children with spinal tuberculosis must be followed-up till skeletal maturity.

Bone and joint tuberculosis has increased in the past two decades in relation with AIDS epidemics. ⋯ Spinal tuberculosis is still a relative common extra spinal manifestation of spinal tuberculosis that requires a high degree of suspicion in order to avoid neurological complications and need of surgery.

Multicenter Study
Are intraspinal anomalies in early onset idiopathic scoliosis as common as once thought? A two centre United Kingdom study.
Rates of neural axis abnormalities in infantile and juvenile idiopathic scoliosis may be as high as 50 %. We aimed to determine the rates of neural axis abnormalities in early onset idiopathic scoliosis patients in a British population. ⋯ This multi-centre study on the largest number of British subjects to date helps to establish the rates of neural axis abnormalities.

To determine the mid-term clinical and radiographic impact of pedicle screw fixation in patients with adolescent idiopathic scoliosis (AIS). ⋯ Intermediate follow-up of patients with AIS treated with an all pedicle screw construct demonstrates maintenance of their coronal, and sagittal plane correction between 2- and 5-year follow-up. At 5 years, improvements in SRS scores were consistent with 2-year values, except for a decline in pain and mental health scores.

A retrospective case review. ⋯ Preoperative Halo-gravity traction followed by non-fusion and growing instrumentation may be effective and safe for young children of CSD associated with SSCM. But it is an ongoing study and additional large multicenter studies are necessary to further assess the safety and efficacy of non-fusion and growing instrumentation.
