Motion Preservation technologies in cervical Spine Surgery
A cervical discectomy and fusion (ACDF) has been a surgical option for the management of cervical disc disorders since 1958 (16). Over time, longterm outcome studies increasingly focused on adverse effects, specifically on the vertebrae and the intervertebral discs adjacent to the level fused (2,8,10). The concern that spinal fusion may potentially contribute to the acceleration of adjacent seg...
متن کاملLoad-displacement properties of lower cervical spine motion segments.
The load-displacement behavior of 35 fresh adult cervical spine motion segments was measured in compression, shear, flexion, extension, lateral bending and axial torsion tests. Motion segments were tested both intact and with posterior elements removed. Applied forces ranged to 73.6 N in compression and to 39 N in shear, while applied moments ranged to 2.16 Nm. For each mode of loading, princip...
متن کاملCoupled motion of cervical spine in three level hybrid constructs.
To compare the biomechanical characters of three-level anterior cervical fusion and hybrid constructs by measuring coupled motion changes of the cervical spine, Eighteen adult human cadaveric cervical spines were biomechanically investigated under eccentric displacement control in lateral bending and axial rotation by measuring vertebral motion (X, Y, Z -axis).The 3DPD condition displayed simil...
متن کاملUltrasound Imaging of Cervical Spine Motion for Extreme Acceleration Environments
Neck and back pain is one of the most common musculoskeletal complaints in personnel in variable acceleration environments such as astronauts and military pilots. Ultrasound is known for dynamic imaging and diagnostic workup of the axial and appendicular skeleton, but is not currently used to image the cervical spine, the injury of which may change the biomechanics of the cervical vertebrae, wh...
متن کاملThree-dimensional analysis of cervical spine segmental motion in rotation
INTRODUCTION The movements of the cervical spine during head rotation are too complicated to measure using conventional radiography or computed tomography (CT) techniques. In this study, we measure three-dimensional segmental motion of cervical spine rotation in vivo using a non-invasive measurement technique. MATERIAL AND METHODS Sixteen healthy volunteers underwent three-dimensional CT of t...
