Mw. Fox et Bm. Onofrio, TRANSDURAL APPROACH TO THE ANTERIOR SPINAL-CANAL IN PATIENTS WITH CERVICAL SPONDYLOTIC MYELOPATHY AND SUPERIMPOSED CENTRAL SOFT DISC HERNIATION, Neurosurgery, 34(4), 1994, pp. 634-640
WE PRESENT SEVEN patients with multilevel cervical spondylotic myelopa
thy and superimposed midline soft disc herniation who were treated by
decompressive laminectomies of the spondylotic segments followed by tr
ansdural excision of the anteriorly located disc extrusion. There was
no perioperative neurological morbidity or mortality associated with t
his operation, and no patients have developed postoperative kyphotic d
eformity with an average follow-up of 50.1 months (range, 24 to 87 mo)
. Two patients had full neurological recovery, whereas five patients h
ad improvement in their preoperative neurological status. We conclude
that a posterior transdural approach may offer an alternative surgical
option for select patients with multilevel cervical spondylosis with
superimposed midline soft disc herniation in whom multiple segment dec
ompression plus access to the anterior spinal canal is necessary.
