Therefore, a systematic comparison of standard pure moment testing without compressive loading versus published and novel compressive loading techniques (follower load, axial load, and combined load) was performed. To achieve a pure moment test, a robot/UFS testing system was programmed with hybrid ...
STUDY DESIGN: Cervical facet capsular strains were determined during bending and at failure in the human cadaver. OBJECTIVE: To determine the effect of an axial pretorque on facet capsular strains and estimate the risk for subcatastrophic capsular injury during normal bending motions. SUMMARY OF BACK...
so named due to the bonyodontoid processprotruding upward into the ring of C1 with which it forms the atlanto-axial joint. Thissynovial jointpermits the atlas to rotate around the axis and accounts for nearly 50% of the rotational motion of the head.17Because they exhibit such unique morpholog...

Thus, given the same loading from the superior vertebral body, the novel prosthesis can disperse the axial load more evenly, resulting in a smaller pressure on the inferior segment, compared with the Prestige LP prosthesis. With regard to the IDP measurement in the fresh-frozen cadaveric ...
The axial force and the moment are measured at the same time point, and the critical values are 6806 N for tension, 6169 N for compression, 310 N-m for flexion, and 135 N-m for extension. The Nij cannot exceed 1.0 at any point in time during a crash test. Airbag interactions, ...

fusion group in flexion, extension, lateral bending, and axial rotation, respectively; the ROMs of C3/4 (P < 0.001) and C5/6 (P < 0.001) in the arthroplasty group were significantly higher than that in the fusion group in flexion, extension, lateral bending, and axial rotation, ...
To establish a generalized equivalent uniform dose (gEUD) -based prescription method for Image Guided Brachytherapy (IGBT) that reproduces the Gyn GEC-ESTRO WG (GGE) prescription for cervix carcinoma patients on CT images with limited soft tissue resolution. Methods The equivalence of two IGBT plan...
test subject to move his head in flexion, extension, lateral bending and axial rotation to the point of reaching the limits of the range of motion. Passive range of motion and passive load-displacement characteristics were measured by instructing the test subject to relax and then applying a ...
