CERVICAL KYPHOTIC MYELOPATHY IN A CHILD WITH MORQUIO-SYNDROME

A child with Morquio syndrome developed severe cervical kyphosis causi ng myelopathy. Decompression of the spinal cord was accomplished by an anterior approach using multilevel corpectomies and stabilization wit h calvarial bone grafts and halo immobilization. The case reported is unique in that cervical cord compression resulted from an uncommon deg ree of cervical kyphosis rather than the usual at lantoaxial instabili ty seen in patients with Morquio syndrome. The operative procedure des cribed shows another example of the usefulness of calvarial bone graft s for cervical spine fusions in children.
