Randomized Controlled Trial Multicenter Study Comparative StudyLower incidence of dysphagia with cervical arthroplasty compared with ACDF in a prospective randomized clinical trial.
The current study of 251 consecutive 1-level anterior cervical reconstructions was undertaken to compare the incidence of dysphagia between cervical disk replacement and conventional anterior cervical fusion and instrumentation. ⋯ In a prospective randomized clinical study the incidence of postoperative dysphagia and the long-term resolution of the dysphagia was greatly improved in the PCM group compared with the instrumented ACDF control group.

Randomized Controlled TrialTumor necrosis alpha-blocking agent (etanercept): a triple blind randomized controlled trial of its use in treatment of sciatica.
Triple blind randomized controlled study. ⋯ Small numbers of trial participants limited statistical analysis. The trend appears to show no benefit to the use of etanercept over placebo in the pharmacologic treatment of sciatica.

Comparative Study Clinical TrialNormal functional range of motion of the cervical spine during 15 activities of daily living.
Prospective clinical study. ⋯ By quantifying the amounts of cervical motion required to execute a series of simulated ADLs, this study indicates that most individuals use a relatively small percentage of their full active ROM when performing such activities. These findings provide baseline data which may allow clinicians to accurately assess preoperative impairment and postsurgical outcomes.

Comparative StudyA short report comparing outcomes between L4/L5 and L5/S1 single-level discectomy surgery.
Prospective cohort study. ⋯ This is the first study comparing a discectomy outcome at L4/L5 and L5/S1 with complete preoperative data. No significant difference exists between the 2 levels in terms of postoperative outcome. Surgical procedures such as fusion or arthroplasty should not be carried out synchronous with primary discectomy for radiculopathy. The lack of a difference between L4/L5 and L5/S1 reinforces the fact that the mechanical environment does not affect outcome and should not influence treatment.

Clinical outcomes after microendoscopic discectomy for recurrent lumbar disc herniation.
Retrospective review of consecutive case series. ⋯ MED is a safe and effective surgical approach for the treatment of recurrent lumbar disc herniation. Standardized measures of outcome show that MED for recurrent herniation produces improvement in pain, disability, and functional health that is at least comparable with outcomes reported for conventional open microdiscectomy.
