Pelvic tilt in neuromuscular disorders

The pelvic tilt is part of a complex deformity in which both the spine and the hip are involved. By viewing the different planes and analyzing the def orming forces, four different types of pelvic tilt in combination with spin al and hip deformities can be identified. In spina bifida patients congenit al deformities of the spine may add to the progression of scoliosis. Analyz ing our own patients we found that certain types of pelvic tilt can be rela ted to certain neuromuscular diseases. Moreover our results show that the p elvic tilt can be effectively corrected by spinal surgery, whereas no effec t of hip surgery could be demonstrated.
