Comparative Study
Comparison between Oxford Cobbmeter and digital Cobbmeter for measurement of Cobb angle in adolescent idiopathic scoliosis.
The purpose of this study was to compare Cobb angle measurements performed using an Oxford Cobbmeter and digital Cobbmeter in a series of 20 adolescent idiopathic scoliosis (AIS) patients. ⋯ We conclude that the smart phone with integrated Tiltmeter and Cobbmeter application is an equivalent Cobb measurement tool to the Oxford Cobbmeter. The advantages of smart phone are the accuracy of determining the most inclined vertebrae and accordingly more precise Cobb angle measurement. The new smart phones with these integrated applications may be really helpful to the spine surgeons, especially in hospitals where PACS or Oxford Cobbmeter is not available.

Different treatment methods including immediate mobilization with or without brace, bed rest or immobilization using thoracolumbosacral orthosis have been applied for stable compression fractures of the pediatric spine. The aim of this study was to evaluate the influence of bracing on the remodeling capacity of pediatric thoracolumbar type A 1.2 impaction fractures. Additionally, the prevalence of pain and functional disabilities were assessed. ⋯ A significant remodeling capacity of thoracolumbar vertebral impaction fractures sustained in childhood is demonstrated. Bracing does not seem to influence the long-term outcome of these injuries. More studies have to be performed to define the role of bracing in these fractures.

To characterize the sagittal alignment of each Lenke type and investigate the relationship between coronal and sagittal deformities in adolescent idiopathic scoliotic (AIS) patients. ⋯ The influence of coronal deformity on sagittal parameters was limited and mainly reflected in the deviation of TK. Most coronal and sagittal parameters were not significantly correlated, and the coronal deformity types did not change the global sagittal postural patterns.

Lumbar disc herniation (LDH) in children is rare. Few studies have evaluated the outcome of surgery and none in a prospective study design. ⋯ Operative treatment of LDH in growing individuals leads to very good outcome with high degree of patient satisfaction.

Comparative Study
Comparison of the scoliosis curve patterns and MRI syrinx cord characteristics of idiopathic syringomyelia versus Chiari I malformation.
Although the more readily available MR imaging has brought about more incidental findings of idiopathic syringomyelia (IS), no published study has specifically addressed the clinical and imaging features of IS-associated scoliosis. Since IS and Chiari I malformation (CMI)-type syringomyelia are hypothesized to share a common underlying developmental pathomechanism, this study aimed to investigate the scoliosis curve patterns and MRI syrinx cord characteristics of patients with IS comparing with those seen in CMI. ⋯ Radiological characteristics of scoliosis were found to be similar between idiopathic and CMI-type syrinx in both the coronal and sagittal planes, adding further evidence to the concept that these entities may be part of a spectrum of disease sharing a common pathophysiological mechanism. The thoracic spine in IS patients tended to be convex to the deviated side of syrinx, which indirectly supported the likely role of spinal cord dysfunction in the pathogenesis of syrinx-associated spinal deformities.
