Comparative Study
Comparison among load-, ROM-, and displacement-controlled methods used in the lumbosacral nonlinear finite-element analysis.
For lumbosacral nonlinear analysis, the characteristics and differences between the load- and range-of-motion (ROM)-controlled methods (LCM and RCM) were compared using the numerical approach. ⋯ The superiority of the computational efficiency of the DCM compared with its counterparts makes it the improved strategy for executing lumbosacral nonlinear analysis.

Factors influencing on retro-odontoid soft-tissue thickness: analysis by magnetic resonance imaging.
A retrospective, consecutive case series. ⋯ There is association between age, sex, degenerative cervical spine changes, and dialysis with retro-odontoid soft-tissue thickness. With dialysis, retro-odontoid soft-tissue thickness increases with increasing duration. Thus, reviewing magnetic resonance image from daily practice indicates that cervical spine degeneration is associated with the development of retro-odontoid pseudotumors.
