摘要: Objective: The goal of this study is to characterize the in situ 6-degree-of-freedom kinematics of the head, 3 vertebrae (T1, T8, and L2), and the pelvis in a 40 km/h frontal impact.关键词:frontal impact spine kinematics helical axis ...
Linear motion is necessary in pedicle based posterior fixation surgeries of the lumbar spine for distraction or compression of the vertebrae, and many current technologies and methods distract and compress only one side of the vertebrae at a time.Tsuge, Brandon Yukio...

Direct repair of multiple pars interarticularis defects after a positive staged pars infiltration test can restore anatomic stability, relieve back pain, and preserve a greater range of motion of the lumbar spine in young patients with intact disc height. 展开 ...
System for stabilizing the spine and reducing spondylolisthesis A system for achieving reduction of curvature of the lumbar region of the spine associated with spondylolisthesis includes transverse plates affixed to vertebrae L4 and L5 and sacral plates affixed to opposite sides of the sacrum. These ....
In cases where surgery includes both lumbar and thoracic vertebrae, patients will be eligible if 50 % or more of the vertebra involved are in the lumbar region. Study procedure Recruitment and sample size The recommended sample size for logistic regression ana- lysis is a minimum of 5 outcome ...

The single IMU was attached to the second lumbar vertebrae using an elastic band (Figure 1b). Multiple IMUs could induce physical burden and discomfort in the elderly in an actual daily living environment [24,25]. Thus, a single IMU was used in this study, and the position of the IMU ...
