Randomized Controlled Trial Comparative StudyRecurrent lumbar disc herniation after conventional discectomy: a prospective, randomized study comparing full-endoscopic interlaminar and transforaminal versus microsurgical revision.
Prospective, randomized, controlled study of patients with recurrent lumbar disc herniations after conventional discectomy, 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, recurrent lumbar disc herniations can be sufficiently removed using the full-endoscopic technique. Full-endoscopic surgery is a sufficient and safe supplementation and alternative to microsurgical procedures.

Randomized Controlled Trial Comparative StudyLumbar spinal fusion versus anterior lumbar disc replacement: the financial implications.
Cost-identification analysis with retrospective and calculated cost. ⋯ The hospital cost of disc replacement surgery is similar to TLIF and ASF (when rhBMP-2 cost is excluded) and is significantly less expensive than ASF/PSF.

Randomized Controlled Trial Multicenter StudyMotion analysis of bryan cervical disc arthroplasty versus anterior discectomy and fusion: results from a prospective, randomized, multicenter, clinical trial.
Prospective, randomized, multicenter clinical trial. ⋯ The Bryan disc treatment, on average, maintained flexion/extension range of motion without degradation over 24 months. No ectopic bridging ossification was seen in any of the Bryan discs and no subsidence or displacement of the Bryan disc occurred.

Randomized Controlled TrialReliability of a magnetic resonance imaging-based grading system for cervical intervertebral disc degeneration.
This was a radiographic reliability study of a novel grading system for cervical intervertebral disc degeneration. ⋯ This grading system is comprehensive and easily applicable with sufficient reproducibility. It can be used as a common nomenclature for research and discussions.

Randomized Controlled TrialPosition of interbody spacer in transforaminal lumbar interbody fusion: effect on 3-dimensional stability and sagittal lumbar contour.
Biomechanical study. ⋯ Difference in ROM and NZ between anterior (TLIF-A) or posterior (TLIF-P) positions was not statistically significant. Similarly, both positions did not influence segmental lordosis.
