The possibility of human error always exists in any operation. But surgeons who have advanced to the level of training required to perform artificial disc replacements (ADRs) rarely have these kinds of problems.
Complications such as bleeding, blood clots, or infection can occur in anyone having any type of surgery. Most of the time, the problems that develop after ADRs include slipping or sinking of the device.
Occasionally movement of the implant can be traced to improper locking at the time of the operation. Most of the time there's no way to predict or prevent migration.
Rarely a technical error such as putting the implant device in place backwards can occur. In such cases a second operation is needed to remove and replace the ADR. Implants come in different sizes (up to 12 for some devices). In a small number of patients, even the smallest implant can still be too large. In such cases, the implant may have to be removed and the spine fused instead.
You'll want to have confidence in your surgeon before having this operation. Don't hesitate to share your concerns. Ask him or her what to expect and even what kinds of complications other patients have had with this procedure.
Studies show a high rate of patient satisfaction with this treatment. The majority of patients report less pain, improved function, and decreased disability. And keeping spinal range of motion is the best advantage over having a spinal fusion.
