Cervical spine disc replacement, also known as cervical disc arthroplasty, is a surgical procedure performed to treat damaged or degenerated discs in the neck. It involves making an incision in the front of the neck to access the affected area. The damaged disc is removed, creating space between the adjacent vertebrae. An artificial disc made of metal or a combination of metal and plastic is then inserted into the disc space. This replacement disc is designed to restore normal disc height and function, allowing for natural movement of the cervical spine. The procedure helps alleviate pain, maintain mobility, and reduce the risk of adjacent segment degeneration.
