What is it? The FDA Approved PRODISC®-L Total Disc Replacement is an artificial intervertebral disc made from metal and plastic that is used to treat pain associated with degenerative disc disease (DDD). DDD is defined as discogenic back pain (pain resulting from a degenerated intervertebral disc) with degeneration of the disc confirmed by patient history and radiographic studies. The PRODISC®-L Total Disc Replacement is implanted to replace a diseased or damaged intervertebral disc during a surgical procedure called spinal arthroplasty.

How does it work? The PRODISC®-L Total Disc Replacement consists of three parts:

1. Two metal (cobalt-chrome alloy) endplates that are anchored to the top and bottom surfaces of the spinal bones (vertebrae)
2. A plastic (ultra-high molecular weight polyethylene, or UHMWPE) inlay that fits between the two endplates
The plastic inlay and endplates help restore the natural distance between the two vertebrae (disc height). The top (superior) endplate can slide over the domed part of the inlay, which can allow movement at the level where it is implanted.

When is it used? The PRODISC®-L Total Disc Replacement is indicated for spinal arthroplasty in patients who:

1. are skeletally mature
2. have degenerative disc disease (DDD) at one level in the lumbar spine (from L3-S1)
3. have no more than Grade 1 spondylolisthesis at the involved level
4. have had no relief from pain after at least six months of non-surgical treatment

What will it accomplish? The PRODISC®-L Total Disc Replacement is used to replace a damaged intervertebral disc. The device may restore disc height, may reduce pain, and may allow movement at the level where it is implanted.

The artificial disc mimics a portion of the behavior of a normal cervical disc. The normal cervical disc allows motion but is restrained at endpoint of motion. That is- the normal disc acts like a bushing where motion at the extreme limits is dampened by the fibers of the annulus. The artificial disc does not have this constraint and this can occasionally put more stress on the facets than the normal disc would. Also, the artificial disc does not have shock absorption capabilities like the normal disc does. This rigidity in compression can allow increased wear. The disc is made of chrome-cobalt alloy. This alloy obscures MRI images so assessment of this segment in the future can become more difficult.

The good news is that this disc seems to have similar results as a normal ACDF fusion does. It may stand the test of time but if it does fail, in general it is relatively easy to repair with a fusion.

What is it? The FDA Approved ProDisc™-C Total Disc Replacement is a device made from metal and plastic that is placed between two adjacent vertebral bodies (neck bones) to replace a diseased cervical disc. The ProDisc™-C Total Disc Replacement consists of three parts:

1. Two metal (cobalt-chrome alloy) endplates that are anchored to the top and bottom surfaces of the adjacent vertebral bodies
2. A plastic (ultra-high molecular weight polyethylene or UHMWPE) inlay that fits between the two endplates

How does it work? The plastic inlay and endplates are intended to restore the natural distance between the two vertebrae (disc height). The top (superior) endplate can slide over the domed part of the plastic inlay, which can allow movement at the level where it is implanted.

When is it used? The ProDisc™-C Total Disc Replacement is intended to be used in skeletally mature patients (people who have stopped growing) for reconstruction of the disc from C3-C7 following removal of the disc at one level for intractable symptomatic cervical disc disease (SCDD), a condition that results from a diseased or bulging disc.

What will it accomplish? The device is intended to stabilize the operated spinal level. Unlike a fusion procedure, the ProDisc™-C Total Disc Replacement is designed to allow motion at the operated spinal level. The effects of the diseased disc removal should include pain relief and improved function.

When should it not be used?The ProDisc™-C Total Disc Replacement should not be implanted in patients with an active infection, allergy to any of the device materials, osteoporosis, marked cervical instability, severe spondylosis, clinically compromised vertebral bodies at the level to be treated, and SCDD at more than one level.
