Randomized Controlled Trial
Circumferential fusion is dominant over posterolateral fusion in a long-term perspective: cost-utility evaluation of a randomized controlled trial in severe, chronic low back pain.
Cost-utility evaluation of a randomized, controlled trial with a 4- to 8-year follow-up. ⋯ Circumferential fusion is dominant over instrumented posterolateral fusion, that is, both being significantly cheaper and significantly better in a long-term, societal perspective.

Observational cohort study. ⋯ Stable vertebral fractures in childhood with no neurologic deficits at injury do not render more degenerative changes than can be expected according to age, but they are associated with more Schmorl's nodes at adjacent disc levels.

An in vitro biomechanical study. ⋯ Extrapolation of the present results indicated dynamic spinal cord compression of up to 88% in those with stenotic canals and 35% in those with normal canal diameters. These results are consistent with the wide range of neurologic injury severity observed clinically due to bilateral facet dislocation.

Case Reports
Brachial neuritis: an under-recognized cause of upper extremity paresis after cervical decompression surgery.
Case series. ⋯ Brachial neuritis appears to be an under-recognized cause of delayed-onset shoulder pain associated with upper extremity weakness that develops as a consequence of the stress of surgery rather than as a complication of surgical technique.
