NuVasive® ACP System Study

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is to evaluate the safety and performance of anterior cervical spine surgery using the NuVasive anterior cervical plate (ACP) System as measured by reported complications, radiographic outcomes, and patient-reported outcomes (PROs).

Detailed Description
-----------------
This study is a prospective, uncontrolled, multicenter study to evaluate the safety and performance of the NuVasive ACP System in patients who undergo anterior cervical spine surgery. Consecutive patients at a given site who meet eligibility requirements will be asked to consent to participate in the study. These patients will present with pathologic conditions in the cervical spine that are amenable to surgical treatment and will be screened prior to study enrollment. Once enrolled in the study, subjects will undergo anterior cervical spine surgery using the NuVasive ACP System based on the surgeon's standard of care. At least 75 subjects will be enrolled and will be followed for 24 months after the surgery.

Eligibility Criteria
-----------------
Inclusion Criteria: Patients who are ≥18 years of age at the time of consent Have planned anterior cervical (C2 to C7) spine surgery using the NuVasive ACP System in conjunction with a NuVasive interbody implant or vertebral body replacement device (VBR), or a structural bone allograft spacer, for treatment of any of the following conditions: degenerative disc disease, as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies trauma (including fractures) tumors involving the cervical spine cervical spinal deformity (kyphosis, lordosis, or scoliosis) failed previous cervical fusion(s) (e.g., pseudoarthrosis) cervical spondylolisthesis cervical spinal stenosis Able to undergo surgery based on physical exam, medical history, and surgeon judgment Understands the conditions of enrollment and is willing to sign an informed consent form to participate in the study Exclusion Criteria: Procedures performed with interbody implants with integrated vertebral body screw(s) Patient is involved in active litigation relating to the spine (worker's compensation claim is allowed if it is not contested) Use of bone growth stimulators postoperatively Active smoking within 6 weeks of surgery Patient has known sensitivity to materials implanted Systemic or local infection (latent or active) or signs of local inflammation Patient has inadequate bone stock or quality, or a physical or medical condition that would prohibit beneficial surgical outcome based on surgeon judgment Pregnant, or plans to become pregnant Patient is a prisoner Patient is participating in another clinical study that would confound study data
