title: Sagittal X-ray parameters in walking or ambulating children with cerebral palsy.
abstract: Adolescents with cerebral palsy (CP) who walk or ambulate often have an abnormal clinical and radiological spinal profile during pubertal growth compared with adolescents of the same age without neuromotor impairments. Therefore, in the following study, we aimed to conduct a radiological assessment of static data on the lumbar-pelvic-femoral complex in ambulatory children with CP to compare these data with those of an asymptomatic population. The CP population was comprised of 119 children and the asymptomatic population was comprised of 652 children. The large format (30×90cm) sagittal X-rays were taken while subjects were in a comfortable position in which knees and hips were in maximal extension. Analyses were performed using Optispine(®) software to measure the parameters of an X-ray of the profile of the spine, pelvis and femurs. Comparing, the two populations, we found no difference in the shape parameter (pelvic incidence) but we did find significant differences in the positional parameters (pelvic tilt and sacral slope) of the pelvis. We found a difference in the curvature and orientation of lumbar lordosis as well as in the number of vertebrae involved in the kyphosis and its orientation. There was also a significant difference in the C7 plumb line. We can say that the CP population is not structurally different from the control population, but that parameters become disturbed during growth. These disturbances should be identified and monitored so that changes can be detected early and progression can be prevented.
