Biomechanical stability using four different posterior cervical fixation techniques was evaluated in human cadaveric spine. ⋯ All four reconstruction techniques restored the stability of the cervical motion segment to at least the level of the intact motion segment before destabilization. An alternative cervical posterior fixation technique, the Wavy Rod system, was considered the most effective technique in stabilizing a cervical motion segment, particularly in axial compression and flexion extension loading.

Qualitative study design, using semi-structured interviews. ⋯ Improvement of the quality of back pain care may still be possible. Implementation strategies should aim at training physicians in communication skills, especially about subjects for debate, where patients' beliefs and experiences color their expectations.

A feasibility study was performed to determine the efficacy of computer assistance in endoscopic spine surgery. ⋯ This technique allows the possibility of computed tomography and magnetic resonance imaging-based, image-guided endoscopic surgery. It is probable that in the near future, as image fusion technology improves, the fluoronavigation based on fluoroscopic images would enable to navigate on multimodal images. Otherwise the technique described in this article is the only reproducible one that allows computed-tomography-based computer assistance during endoscopic procedures.
