[Axis deviation of lumbar spine due to abdominal expanding lesions in children (author's transl)]

The deviation of the physiologic lordosis of the lumbar spine is described in 40 cases of abdominal expanding lesions. One can find a lumbar kyphosis between L2 and L4 in retroperitoneal and a straightening between Th12 and L2 in intraperitoneal lesions. The evidence of a deviation of the lumbar axis is an indirect sign for further localisation of the tumor.
