Comparing Costs and Outcomes of Two Surgeries for Cervical Degenerative Disc Disease Anterior Cervical Discectomy With Fusion vs. Arthroplasty

What this Trial Is About

Researchers are evaluating two surgical techniques for treating cervical degenerative disc disease CDDD, which causes symptoms like radiculopathy and myelopathy. The study compares anterior cervical discectomy with fusion ACDF, a common surgery that fuses spinal segments, to anterior cervical discectomy with arthroplasty ACDA, which preserves motion at the operated segment. The main goal is to determine which technique is more cost-effective over the long term, considering both health outcomes and societal costs, as no clear consensus currently exists on this matter. Participants will be randomly assigned to receive either ACDF or ACDA surgery. Both procedures begin with removing the damaged disc through an anterior approach. In ACDF, a cage is implanted to fuse the vertebrae, while in ACDA, a cervical disc prosthesis is placed to preserve motion. These interventions can be performed at a single or multiple spinal levels. Postoperative care includes wound closure and drain placement as needed. During the study, participants will be followed for up to four years with assessments at baseline and every six months. Researchers will collect clinical and radiological data, including measures of neck disability, pain scales, anxiety and depression levels, and neurological function. They will also evaluate the development of clinical adjacent segment pathology CASP and perform a process evaluation related to the surgical treatment. The focus is on both the effectiveness and costs associated with each surgical technique from a societal viewpoint.
