An accurate description of the biomechanical behavior of the spine is crucial for the planning of scoliotic surgical correction as well as for the understanding of degenerative spine disorders. The current clinical assessments of spinal mechanics such as side-bending or fulcrum-bending tests rely on the displacement of the spine observed during motion of the patient. Since these tests focused solely on the spinal kinematics without considering mechanical loads, no quantification of the mechanical flexibility of the spine can be provided. ⋯ In summary, the SST seems suitable to provide pre-operative information on the complex functional behavior and stiffness of spinal segments under physiological loading conditions. Such tools will become increasingly important in the future due to the ever-increasing complexity of the surgical instrumentation and procedures.

Comparative Study
Effect of vertebroplasty with bone filler device and comparison with balloon kyphoplasty.
To evaluate the effect of vertebroplasty with a bone filler device compared with balloon kyphoplasty. ⋯ Vertebroplasty with a bone filler device could achieve equivalent compression reduction and bone cement leakage rate, as well as greater sponge-type bone cement distribution, which were advantages over balloon kyphoplasty.

To introduce a modified technique of thoracoplasty (short apical rib resection thoracoplasty (SARRT)) and compare its clinical, functional radiological outcomes and postoperative lung functions with conventional thoracoplasty (CT) in scoliosis surgery. ⋯ SAART is effective in correcting the rib deformity without altering the pulmonary functions and SAART has less number of pulmonary complications as compared to CT.

Comparative Study
Altered head orientation patterns in children with idiopathic scoliosis in conditions with sensory conflict.
Idiopathic scoliosis (IS) is the most common spinal deformity in adolescents. Defective postural equilibrium may be a contributing factor. The information of the three sensory systems combined enables the formation of a central representation of head position and body posture. Comparison of head angles of girls with and without scoliosis may result in a difference in head orientation. ⋯ The differences between groups for different age categories suggest that the process of development of sensory integration for estimation of verticality appears to be different for girls with scoliosis.

The sagittal vertical axis (SVA) is a meaningful measurement and widely used for evaluating sagittal balance, and is considered a design standard for surgery, including most ankylosing spondylitis (AS) kyphotic deformity planning. However, recent research indicates that the C7 plumb line is actually not the center of gravity (CG) line. Therefore, whether there is a better radiological marker as the CG of the trunk for AS thoracolumbar kyphosis remains unknown. This research is to investigate a radiological marker for the CG of the trunk in lateral radiographs for AS thoracolumbar kyphosis. ⋯ The hilus pulmonis fell approximately on the hip axis both pre- and post-operatively. It was a better marker as the center of gravity of the trunk for deformity planning for AS thoracolumbar kyphosis.
