Abstract
|
|
|
Spinal arachnoid cysts are a rare disease with an unknown origin. Because of their broad base, a total laminectomy with or without fusion has been the treatment of the choice. We encountered 5 patients with a spinal arachnoid cyst who were treated by recapping laminoplasty after pars osteotomy. This procedure has not been reported in Korea. All patients showed neurological recovery with no recurrence of the cyst. The findings on the stressed plain film confirmed bony union and stability of the posterior element.
No complications such as postoperative spinal canal stenosis, facet arthrosis or kyphosis were observed. Among the various surgical options for the extirpation of arachnoid cysts, recapping laminoplasty appears to be a good but technically demanding procedure.
