Prospective cohort study. ⋯ In this sample of workers' compensation recipients, the high procedure cost of SCS was not counterbalanced by lower costs of subsequent care, and SCS was not cost-effective. The benefits and potential cost savings reported in RCTs may not be replicated in workers' compensation patients treated in community settings.

Controlled Clinical Trial
Gastroesophageal reflux after anterior cervical surgery: a controlled, prospective analysis.
Prospective controlled clinical study. ⋯ Compared to the lumbar control group, patients in the cervical group had increased incidence, and severity of GERD-like symptoms in the early postoperative period.
-
A case report. ⋯ The case report highlights the clinical significance of the atypical posterior SN that could be a channel for large disc extrusion after a traumatic event in Scheuermann's disease and the clinical importance of surgeon's close attention to the possibility of abruptly progressing neurologic compromise in this situation.

This longitudinal experimental study was conducted to investigate electrophysiologic characteristics, pain behavior, and histological changes in a rat model of lumbar disc herniation. ⋯ Neuropathic pain and pathologic changes in spinal nerve fibers probably remain even after ASAs in EMG have disappeared in our rat model of lumbar disc herniation. These results provide baseline data concerning the natural courses of electrophysiologic findings and of radicular pain in patients with intervertebral disc herniation.

Review
Safety and effectiveness of bone allografts in anterior cervical discectomy and fusion surgery.
Systematic review. ⋯ ACDF with allograft, ACDF with autograft, ACDF with cage, and cervical disc arthroplasty show similar improvements in pain, function, and quality of life with correspondingly low adverse event rates. All ACDF procedures result in high fusion rates.
