Paralysis, muscle imbalance, and spasticity resulting from myelomening
ocele produce orthopedic deformities that often require surgical corre
ction. Spinal deformities in myelomeningocele are nearly universal, an
d are difficult to treat because of the absence of posterior elements.
Hip dislocations frequently occur, but rarely require treatment. Seve
re foot deformities are seen in up to 80% of children.
