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.

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.
