Spinal Arachnoid Cyst: Treated with Pars Osteotomy and Recapping Laminoplasty: Report of 5 Cases / 대한척추외과학회지

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.
