STUDY DESIGN Pelvic dynamic analysis in adolescents with idiopathic scoliosis (AIS). OBJECTIVE To examine and characterize pelvis dynamics in AIS. SUMMARY OF BACKGROUND DATA Although studies have examined spine and pelvis postural differences between female adolescents with and without scoliosis much is still unknown about the dynamics of pelvis in(More)
STUDY DESIGN Three-dimensional (3D) analysis of the spinopelvic alignment in adolescent idiopathic scoliosis (AIS). OBJECTIVE To study the 3D pelvic alignment with respect to the spinal deformities in AIS subgroups. SUMMARY OF BACKGROUND DATA Spinopelvic alignment is subject to change in scoliosis. Many sacropelvic parameters were developed to(More)
BACKGROUND Posterior spinal surgical correction is performed to correct spinal deformities in adolescent idiopathic scoliosis. Although the relative spino-pelvic alignment changes after spinal surgery, pelvis remains unfused in idiopathic scoliosis surgery. The impact of the spinal fusion on the transferred load to the pelvis via sacrum is not documented in(More)
Posterior spinal fusion and instrumentation is used to correct the spinal deformities in scoliosis. However the effects of this intervention on the biomechanical loading of the distal unfused vertebrae particularly the sacrum are not well documented. The objective of this study was to develop the patient-specific models to simulate the biomechanical loading(More)
Posterior spinal instrumentation and fusion techniques are used over decades to correct spinal deformities higher than 40 degrees in scoliotic subjects [1]. Although these methods are successfully decreased the spinal curvature in scoliosis, the biomechanical loading of the distal unfused vertebrae is not well studied after operation. Among unfused(More)
BACKGROUND The pelvis maintains an important role in transferring loads from the upper body to the lower extremities and hence contributes to the standing postural balance. Even though changes in spino-pelvic relative alignment are involved in the pathophysiology of scoliosis, the mechanism through which the transferred load between the spine and pelvis is(More)
