ARTIFICIAL CERVICAL DISC REPLACEMENT

An artificial cervical disc is an implant inserted between two vertebrae in the neck to replace a damaged disc and keep the disc mobile and prevent adjacent segment degeneration (ASD). It is an alternative to the commonly performed anterior cervical discectomy and fusion (ACDF), a surgical procedure that is designed to remove the disc and stop motion at that segment by fusion.

Artificial disc replacement (ADR) surgery—also known as a total disc arthroplasty or total disc replacement (TDR)—is typically performed for a patient with a cervical disc herniation that is causing significant neck pain and/or arm pain  with/ without neurological deficit like numbness or weakness in the limbs. It is generally offered when nonsurgical treatment options have failed.

 

CASE STUDY

A 31 years old female was admitted with history of neck pain for 2 years with pain radiating upto left index finger on the dorsal aspect. She also complained of numbness of the left thumb and index finger for four months.  

PROCEDURE - C6-7 anterior cervical microdiscectomy along with placement of artificial cervical disc under general anesthesia (Medtronic-prestige).
