The relative contribution of intervertebral disc and vertebral wedging to the development of thoracic kyphosis and lumbar lordosis in asymptomatic adolescents

چکیده
Methods and materials A retrospective study of 170 asymptomatic adolescent volunteers was performed and all of them had the standing whole-spine lateral radiography. All subjects were divided into 3 groups by age: Group A (10-12 years), Group B (13-15 years), and Group C (16-18 years). Four different radiographic parameters were measured: lumbar lordosis (LL, L1-L5), thoracic kyphosis (TK, T4-T12), wedging angle of each disc and vertebra between T4 and L5. In addition, the percent of the sum of T4-T12 disc/vertebral wedging angle in the TK and the sum of the L1-L5 disc/vertebral wedging angle in the LL were calculated.

Vertebral body or intervertebral disc wedging: which contributes more to thoracolumbar kyphosis in ankylosing spondylitis patients?
Both vertebral body wedging and disc wedging are found in ankylosing spondylitis (AS) patients with thoracolumbar kyphosis. However, their relative contribution to thoracolumbar kyphosis is not fully understood. The objective of this study was to compare different contributions of vertebral and disc wedging to the thoracolumbar kyphosis in AS patients, and to analyze the relationship between th...

BACKGROUND Hueter-Volkmann's law regarding growth modulation suggests that increased pressure on the end plate of bone retards the growth (Hueter) and conversely, reduced pressure accelerates the growth (Volkmann). Literature described the same principle in Rat-tail model. Human spine and its deformity i.e. scoliosis has also same kind of pattern during the growth period which causes wedging in...
