Biomechanics of the upper cervical spine ligaments in axial rotation and flexion-extension: Considerations into the clinical framework.

ABSTRACT:

Context

The motion of the upper cervical spine (UCS) has a great interest for analyzing the biomechanical features of this joint complex, especially in case of instability. Although investigators have analyzed numerous kinematics and musculoskeletal characteristics, there are still little data available regarding several suboccipital ligaments such as occipito-atlantal, atlantoaxial, and cruciform ligaments.

Objective

The aim of this study is to quantify the length and moment arm magnitudes of suboccipital ligaments and to integrate data into specific 3D-model, including musculoskeletal and motion representation.

Materials and methods

Based on a recent method, suboccipital ligaments were identified using UCS anatomical modeling. Biomechanical characteristics of these
