Evaluating The Safety and Effectiveness of The NeoDisc™ Versus ACDF in Subjects With Single-Level Cervical Disc Disease

Summary

The purpose of the study is to evaluate the safety and effectiveness of the NeoDisc compared to anterior cervical discectomy and fusion (ACDF) for the treatment of single-level cervical disc disease, by demonstrating non-inferior comparative results at the 24 month follow-up period pertaining to (1) improvement in the Neck Disability Index (NDI) score, (2) revision/reoperation/removal rate, (3) complication rate, and (4) maintenance or improvement in neurologic status.

Detailed description

The NeoDisc is an artificial cervical intervertebral disc replacement intended for clinical use following a discectomy. Implantation of the device will result in artificial replacement of a pathologically damaged or surgically removed cervical disc. Use of the device also obviates the need to harvest bone graft from the patient's iliac crest, a common and painful part of current surgical techniques. The NeoDisc is indicated for cervical spinal arthroplasty in skeletally mature subjects with symptomatic cervical disc disease at one level from C3 to C7. Symptomatic cervical disc disease is defined as image-confirmed herniated disc, spondylosis, and/or loss of disc height, with functional neurological deficit (i.e., exhibits at least one sign associated with cervical level to be treated, including abnormal reflex, decreased motor strength, abnormal dermatome sensitivity, or pain in a dermatomal distribution).
