Brief Summary

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.

Outcome Measures

Primary Outcomes (7)

• Evolution of the sagittal spinal statics in the sitting position

  measurement of pelvic incidence (normal values between 35 and 85 degrees)

  At baseline

• Evolution of the sagittal spinal statics in the sitting position

  sacral slope (angle of inclination of the sacral plateau in profile to the horizontal (degrees))

  At baseline

• Evolution of the sagittal spinal statics in the sitting position

  pelvic version (angle between the vertical and the line joining the center of the femoral heads with the middle of the sacral plateau (in degrees))

  At baseline

• Evolution of the sagittal spinal statics in the sitting position

  lordoses cervicales (in degrees)

  At baseline

• Evolution of the sagittal spinal statics in the sitting position

  lumbar lordosis (in degrees)

  At baseline

• Evolution of the sagittal spinal statics in the sitting position

  thoracic kyphosis (in degrees)

  At baseline

• Evolution of the sagittal spinal statics in the sitting position

  Cobb angle (if scoliosis) (curvature greater than 10 degrees : definition of scoliosis; between 10 and 15 degree: benign scoliosis; between 15 and 35 degrees: moderate scoliosis; curvature greater than 35 degrees: significant scoliosis.)

  At baseline

Study Arms (1)

Child with Cerebral Palsy

Children and adolescents from 4 to 17 years old with cerebral palsy GMFCS III, IV or V followed in the Physical Medicine and Rehabilitation Department, Children's Rehabilitation Unit of the University Hospital of Nîmes (Carémeau Hospital)

Radiation: spine and pelvis radiography

Interventions

spine and pelvis radiography RADIATION

X-ray of the spine and pelvis from the front and the side will be performed under the standardized conditions that we put in place: in a sitting position on a specific modular chair.
