“…48,49 Although there is a gap in the CDA literature regarding implant design and its impact on wear, there is extensive literature in adult reconstruction supporting the use of polyethylene polymer, and the use of highly cross-linked ultrahigh molecular weight polyethylene has become the standard of care in total hip arthroplasty. 79,80 Similarly, studies on disc arthroplasty are beginning to show similar trends in wear patterns for metal-onpolymer compared with metal-on-metal designs. [50][51][52] While metal-on-metal designs can decrease the amount of wear debris, they have been associated with metal hypersensitivity and complications leading to implant failure.…”

Study Design: A narrative review. Objective: This review discusses the short and long-term complications associated with cervical disk arthroplasty (CDA). Summary of Background Data: CDA is a safe and effective motion-sparing alternative to fusion for the treatment of cervical disk pathology in patients with cervical radiculopathy or myelopathy. Although CDA offers advantages over fusion within a narrower set of indications, it introduces new technical challenges and potential complications. Methods: A systematic search of several large databases, including Cochrane Central, PubMed, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry, was conducted from January 2005 to August 2023 to identify published studies and clinical trials evaluating cervical disk replacement complications and outcomes. Results: Short-term complications are primarily related to surgical approach and include dysphagia reported as high as ~70%, laryngeal nerve injury ~0%–1.25%, Horner syndrome ~0.06%, hematoma ~0.01%, gross device extrusion ~0.3%, whereas long-term complications include adjacent segment disease reported at ~3.8%, osteolysis ~44%–64%, heterotopic ossification ~7.3%–69.2%, implant failure ~3.3%–3.7%, and implant wear, which varies depending on design. Conclusions: Approaches for mitigating complications broadly include meticulous dissection, intraoperative techniques, and diligent postoperative follow-up. This review emphasizes the need for a comprehensive understanding and management of complications to enhance the safety, reproducibility, and success of CDA. As CDA continues to evolve, there remains a critical need for ongoing research to delve deeper into evaluating risk for complications and long-term patient outcomes.
