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.

Gait analysis in low lumbar myelomeningocele patients with unilateral hip dislocation or subluxation.

The surgical indications for the treatment of unilateral hip dislocations or subluxations in patients with low lumbar myelomeningocele remain highly debatable. This study examines the influence of unilateral hip dislocation or subluxation on the gait of these patients using three-dimensional gait analysis. Twenty patients with a diagnosis of low lumbar myelomeningocele underwent three-dimensional gait analysis.

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.
