Study of Sagittal Pelvic Statics in the Sitting Position in Children With Cerebral Palsy

Cerebral palsy is the leading cause of motor disability in children. Children with little or no walking (GMFCS III, IV and V) represent 43% of children with cerebral palsy, the majority of whom present pelvic and spinal deformities in the frontal and sagittal planes. However, sagittal pelvic spinal statics have been little studied, especially in the sitting position, which is the functional position of these children.Moreover, there are currently no recommendations on how to perform follow-up radiographs of the spine in children who do not walk much.A better understanding of pelvic and sagittal spinal statics would help prevent deformities and their complications.Standardizing the method of performing pelvic-spinal radiographs in the sitting position will make monitoring of spinal statics more reliable.
