Information for the public
Inserting an implant (called an annular disc implant) involves closing the hole that is left in a torn disc after any bulging material has been removed during surgery. Typically, the implant used to close the hole is made of a metallic part that is inserted into the bone next to the torn disc and a mesh part made of woven plastic-like material that is inserted into the tear. You will be given a general anaesthetic. A type of X‑ray, fluoroscopy, may be used during the procedure to help the surgeon put the implant in the correct place.
