Expansive Laminoplasty for Cervical Myelopathy With Interconnected Porous Calcium Hydroxyapatite Ceramic Spacers

Abstract

The IP-CHA spacer contributed to high bone fusion rates of the spacers and hinges of the laminae, and there were no complications associated with their use. Cervical laminoplasty with the IP-CHA spacers is a safe and simple method that yields sufficient fixation strength and provides sufficient bone bonding within a short period of time after operation.
