Fig. 1From: Clinical outcomes of laminoplasty for patients with lysosomal storage disease including mucopolysaccharidosis and mucolipidoses: a retrospective cohort study A 37-year-old male patient with MPS type II. Double door laminoplasty combined with C1 posterior arch resection and partial resection of the foramen magnum dorsal wall. A HA spacers were placed and ligated between the opened laminae. B Axial CT image of the lamina before operation. C Opened laminar and HA spacer (same level as B). D T2WI MR image of the cervical spine before operation. E T2WI MR image of the same patient at 6 months after surgery. Note that the cervical spinal canal was expanded. The high intensity area at the C1/2 level became more evident and that at the C5/6 level disappeared after surgery.
