Analyse cinématique tridimensionnelle du rachis cervical sain et pathologique in vivo.

Abstract : The cervical spine is composed of hard and flexible components connecting the chest and the skull. Cervical mechanical disorders and their consequences are a current problem. Biomechanics provides relevant tools to quantify the kinematic of the cervical spine in order to obtain objective data supporting the clinical diagnosis or the evaluation 'of the therapeutic treatment effectiveness. The aim of this Ph.D. thesis is to improve the analysis of the impact of cervical degenerative or traumatic diseases on the 3D kinematics of the cervical spine in vivo. A global approach characterizing the 3D nobilities of the cervical spine was developed using a non-invasive specific protocol that has been evaluated in regards of the accuracy and the reproducibility. The cervical kinematic characterization, according to age and gender, were obtained on a large database of asymptomatic subjects. This database was used as a reference to demonstrate the feasibility of the quantification of pathological impact on the cervical kinematic in regards of different pathologies. A segmental approach has been proposed to quantify the contribution of each cervical unit in spinal movement. A 3D reconstruction method of the cervical spine from biplane X-rays was implemented in order to quantify the 3D segmental cervical spine magnitude in the 3 space planes during pseudo-dynamic X-rays.Thi s study proposes an original and relevant approach combining global and segmental point of view in order to characterize cervical performances. This study led to relevant perspectives about the combination of cervical global and segmental approach in order to better understand and quantify cervical disorders.
