Spondylosis

The aim of this study is to prospectively investigate the potential for bony fusion of ViviGen® bone graft substitute in comparison to rhBMP-2 in monosegmental ALIF procedure L5/S1 and in monosegmental XLIF procedure L4/5

The goal of this clinical trial is to evaluate safety and tolerability of multiple oral doses of EC5026 in male and female patients with neuropathic pain due to traumatic or non-traumatic (degenerative) spinal cord injury. The main question it aims to answer is whether EC5026 is safe and well tolerated in SCI patients with neuropathic pain. In addition, this trial will also study the effects of EC5026 on pain. Researchers will compare EC5026 to placebo. Participants will be asked to: * Take EC5026 or placebo in a masked fashion, once daily, for 14 consecutive days. * Undergo physical exams, vital signs assessments, ECGs, and blood draws * Complete assessments of pain, sleep, functional status, and perception of change

The study is a prospective, first-in-human, multi-center, non-randomized, single-arm study to assess the safety and efficacy of the CEM-Cage used with the CEM-Plate in patients who are appropriate candidates for a 2-level anterior cervical discectomy and fusion (ACDF). Fifty patients will be enrolled in the study and, after undergoing a 2-level ACDF, will be evaluated at 4 weeks, 3 months, 6 months, 12 months, 18 months, and 24 months.

Opioid overdose suppresses brainstem respiratory circuits, causes apnea, and may result in death. Epidural electrical stimulation (EES) at the cervical spinal cord facilitated motor activity in rodents and humans, and we hypothesized that EES of the cervical spinal cord could antagonize opioid-induced respiratory depression in humans. In this study, we will stimulate the spinal cord during surgery and assess its effects on respiratory function in human patients.
