Trunk kinematics and the influence on valgus knee stress in persons with high sacral level myelomeningocele.

Historically, trunk movement has been thought to be reactionary to lower body motions. The excessive trunk movement in patients with myelomeningocele may be a primary mechanism during ambulation. The purpose of this study was to quantify three-dimensional trunk movement in patients with myelomeningocele.

Spastic hemiplegic cerebral palsy and the femoral derotation osteotomy: effect at the pelvis and hip in the transverse plane during gait.

Gait analysis techniques were used to evaluate the outcome of the femoral derotation osteotomy in children with hemiplegic cerebral palsy. Seventy-one patients were evaluated and classified according to the Winters and Gage scale. Nine of the 13 patients classified as type IV underwent a femoral derotation osteotomy.
