Assessment of the reliability of standardized magnetic resonance imaging (MRI) interpretations and measurements. ⋯ Classification of disc morphology showed substantial intra- and inter-reader agreement, whereas thecal sac and nerve root compression showed more moderate reader reliability. Quantitative measures of canal and thecal sac area showed good reliability, whereas measurement of disc fragment area showed more modest reliability.

Retrospective study. ⋯ Microscope-assisted "free-hand" C1 lateral mass screws insertion is a feasible and reproducible technique. which offers an alternative method of screw insertion without cumbersome and potentially harmful fluoroscopy.
-
A prospective, cohort evaluation of 262 consecutive patients who underwent transforaminal endoscopic excision for recurrent lumbar disc herniation, after previous discectomy. ⋯ ETD for recurrent disc herniation seems to be an effective method with few complications and a high patient satisfaction.
-
Retrospective case review of children completing dual growing rod treatment at our institutions. Patients had a minimum of 2 years follow-up. ⋯ Dual growing rod technique resulted in 5.7 +/- 2.9 cm of spinal growth during a 4.37 +/- 2.4 year treatment period. There was significantly greater growth and correction achieved in those lengthened more frequently.

Multicenter Study Comparative Study
Traumatic thoracic and lumbar spinal fractures: operative or nonoperative treatment: comparison of two treatment strategies by means of surgeon equipoise.
A center parallel cohort study with blinded inclusion based on clinical equipoise. ⋯ Overall outcome of nonoperative and operative treatment in middle-long-term follow up is comparable, although there seems to be a difference in neurologic recovery patterns. Studies on the cost-effectiveness of treatment options and the patterns of recovery within 2 years after injury would assist in guideline development and stimulate interest for future research.
