Proposal of a Cervical Sagittal Classification System to Guide Surgical Treatment for Adult Cervical Deformity

We define normative cervical alignment utilizing the MEANS cohort and propose a classification system to identify the spinal region driving the cervical deformity. Types 1A-B represent well-compensated alignment. Type 2 and 3 were considered to have deformities in the cervical spine and thoracolumbar spine, respectively. Type 4 spines have a combined deformity. This can help guide the surgeon to determine the appropriate region that should be addressed with surgery.

Abstract

We define normative cervical alignment utilizing the MEANS cohort and propose a classification system to identify the spinal region driving the cervical deformity. Types 1A-B represent well-compensated alignment. Type 2 and 3 were considered to have deformities in the cervical spine and thoracolumbar spine, respectively. Type 4 spines have a combined deformity. This can help guide the surgeon to determine the appropriate region that should be addressed with surgery.
