In Vivo Three-Dimensional Kinematics of the Cervical Spine during Head Rotation in Patients with Degenerative Cervical Spine
INTRODUCTION: In vivo three-dimensional (3D) kinematic changes associated with degeneration of the cervical spine have not previously been well described since they are too complicated to elucidate using conventional radiography or computed tomography techniques. We have developed a 3D imaging system to evaluate the relative motion of individual cervical vertebra in vivo and reported the kinema...

ABSTRACT Low back pain is the most common musculoskeletal disease and has a high prevalence rate in community that causes a significant morbidity, mostly due to degenerative discovertebral disease. MRI is the best and noninvasive method for assessing degenerative discovertebral disease. This study was conducted to determine MRI findings in degenerative discovertebral disease. This descri...
متن کاملMotion compensation associated with single-level cervical fusion: where does the lost motion go?
STUDY DESIGN Seven adult human cadaveric cervical spines (C2-T1) were biomechanically tested in a programmable testing device. OBJECTIVE Compare the effects of incremental single-level fusion at different levels of the cervical spine. SUMMARY OF BACKGROUND DATA Clinical studies have reported degenerative symptomatic disc disease at disc levels adjacent to fusion. No known study has attempte...
متن کاملKinematic evaluation of the spine: a kinetic magnetic resonance imaging study.
Kinetic magnetic resonance images (kMRIs) of 587 lumbar and 459 cervical spines of symptomatic patients in axially loaded, upright neutral (0 degrees), flexion (40 degrees), and extension (-20 degrees) positions were evaluated. Imaging took 10 to 12 minutes to complete in each position. Cervical kinematics were significantly affected by intervertebral disc degeneration, cervical cord compressio...
متن کاملDegenerative Changes of Spine in Helicopter Pilots
OBJECTIVE To determine the relationship between whole body vibration (WBV) induced helicopter flights and degenerative changes of the cervical and lumbar spine. METHODS We examined 186 helicopter pilots who were exposed to WBV and 94 military clerical workers at a military hospital. Questionnaires and interviews were completed for 164 of the 186 pilots (response rate, 88.2%) and 88 of the 94 ...
