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.

Randomized Controlled Trial Comparative Study
Full-endoscopic interlaminar and transforaminal lumbar discectomy versus conventional microsurgical technique: a prospective, randomized, controlled study.
Prospective, randomized, controlled study of patients with lumbar disc herniations, operated either in a full-endoscopic or microsurgical technique. ⋯ The clinical results of the full-endoscopic technique are equal to those of the microsurgical technique. At the same time, there are advantages in the operation technique and reduced traumatization. With the surgical devices and the possibility of selecting an interlaminar or posterolateral to lateral transforaminal procedure, lumbar disc herniations outside and inside the spinal canal can be sufficiently removed using the full-endoscopic technique, when taking the appropriate criteria into account. Full-endoscopic surgery is a sufficient and safe supplementation and alternative to microsurgical procedures.

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.
