cervical arthroplasty
A motion-preserving surgical procedure that replaces a cervical disc with an artificial disc prosthesis.
Full Definition
Cervical arthroplasty, also known as cervical disc replacement or artificial disc replacement, is a surgical alternative to fusion for treating cervical disc pathology. The procedure involves removing the degenerated disc and replacing it with a prosthetic device designed to preserve motion at the treated level. This motion preservation may reduce the risk of adjacent segment disease compared to fusion procedures. Patient selection is critical, with strict criteria including single-level disease, adequate bone quality, and absence of significant facet arthropathy or instability.
Usage
Usage note: Specify device manufacturer and model when applicable; ensure proper patient selection criteria are documented.
