An in vitro biomechanical study of the effectiveness of halo-vest fixation. ⋯ The present results, which document snaking motion of the cervical spine due to the halo-vest, indicate that an inadequately fitting or loose vest may significantly diminish its immobilization capacity leading to delayed healing or nonunion.

A 2-group experimental design. ⋯ After IMF, control subjects use a rigid proprioceptive postural control strategy, rather than the normal "multisegmental" control, which is similar to people with LBP. This results in decreased postural stability. These results suggest that IMF might be a factor in the high recurrence rate of LBP.

The assignment of adolescent idiopathic scoliosis (AIS) curves into curve types (1-6), as described by Lenke et al, was evaluated by 12 independent observers using the original description versus a decisional tree algorithm. ⋯ Transfer of a computer algorithm, a decision tree, to a clinical diagram improved both accuracy ofAIS classification. Algorithmic diagrams could prove beneficial to increase classification reliability due to their systematic approach.

A descriptive cadaveric study measuring arterial tension. ⋯ The results of this study would be useful for not only spinal surgery but also other vascular surgeries, particularly, in cases where patients with conditions such as atherosclerosis or stenosis.
