Multicenter Study
Analysis of risk factors for loss of lumbar lordosis in patients who had surgical treatment with segmental instrumentation for adolescent idiopathic scoliosis.
Iatrogenic flattening of lumbar lordosis in patients with adolescent idiopathic scoliosis (AIS) was a major downside of first generation instrumentation. Current instrumentation systems allow a three-dimensional scoliosis correction, but flattening of lumbar lordosis remains a significant problem which is associated with decreased health-related quality of life. This study sought to identify risk factors for loss of lumbar lordosis in patients who had surgical correction of AIS with the use of segmental instrumentation. ⋯ This study identified important risk factors for decrease of lumbar lordosis in patients who had surgical treatment for AIS with segmental pedicle screw instrumentation, including a high preoperative lumbar lordosis, surgical decrease of thoracic kyphosis, and factors attributable to a particular operating surgeon that were not quantified in this study.

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.

5-Aminolevulinic acid (5-ALA)-based fluorescence-guided surgery was shown to be beneficial for cerebral malignant gliomas. Extension of this technique for resection of meningiomas and cerebral metastasis has been recently evaluated. Aim of the present study is to evaluate the impact of fluorescence-guided surgery in spinal tumor surgery. ⋯ The present study demonstrates that spinal intramedullary gliomas and the majority of spinal intradural meningiomas are 5-ALA positive. As a surgical consequence, especially in intramedullary gliomas, the use of 5-ALA fluorescence seems to be beneficial.

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.
