A single-centre retrospective study of prospectively collected data. ⋯ Treatment of far lateral nerve root compression showed an overall good patient-reported outcome, but with less improvement with advanced CSCA. Modified approaches and techniques might be preferable for levels L5/S1.

This study is a systematic review. ⋯ This systematic review summarizes the heterogeneous evaluations of ergonomics in spine surgery. Overall, upwards of three-quarters of spine surgeons have reported musculoskeletal discomfort, most commonly presented as back pain, neck pain, and hand/wrist discomfort. These symptoms are often exacerbated by the use of loupes, operating bed height, and extended periods of time in various positions. Studies demonstrate that physical discomfort is associated with the surgeons' mental and emotional well-being, leading to stress, burnout, and reduced job satisfaction, all of which impact patient care.

Comparative Study
Biomechanical Comparison of Different Surgical Strategies for Skip-level Cervical Degenerative Disc Disease: A Finite Element Study.
We constructed finite element (FE) models of the cervical spine consisting of C2-C7 and predicted the biomechanical effects of different surgical procedures and instruments on adjacent segments, internal fixation systems, and the overall cervical spine through FE analysis. ⋯ Noncontiguous ACDF with zero profile can reduce the stress on adjacent intervertebral disks and endplates, resulting in a reduced risk of adjacent segment disease development. However, the high cortical bone stress caused by the Zero-P device may influence the risk of fractures.

Observational Study
Natural History of IntraDiscal Vacuum Phenomenon and its role in Advanced Disc Degeneration.
Observational serial computed tomography (CT) analysis of the lumbar spine in a normal-aging population. ⋯ As disc degeneration advances, the associated IDVP persists in most cases, displaying a plateauing of severity over long periods, but rarely with progression to autofusion.

A prospective, comparative study on clinical, radiographic, and health-related quality of life (HRQoL) outcomes in adolescents with acute spondylolysis treated with a rigid thoracolumbar orthosis (Boston brace) or with a placebo (elastic lumbar support) with a 2-year follow-up time. ⋯ II.
