[Surgical therapy of severe knee flexion and hip flexion contractures in caudal regression syndrome].

In severe cases of caudal-regression syndrome one usually can find hip-flexion and knee-flexion-contractures, which can hardly be treated. We report about a new possibility of operative treatment. In this case we correct the contractures with a shortening of the proximal part of the femur and with a resection-arthrodesis of the knee-joint. The clinical result, which we obtained by this way, allows the orthotic management with an orthoprosthesis. The maintaining mobility of the hip joint and the sitting-comfort is very sufficient.
