The ProDisc-L total disc replacement has been determined to be safe and effective in the treatment of degenerative disc disease (DDD) at one level from L3-S1. During the total disc replacement procedure, the diseased intervertebral disc is removed and replaced with a motion preserving ProDisc-L implant. The ProDisc-L total disc replacement surgery is intended to:
Remove the diseased disc
Restore disc normal height
Reduce discogenic pain
Provide the potential to preserve motion in the affected vertebral segment
The ProDisc-L implant design is based on a ball and socket principle. The ProDisc-L implant is composed of three implant components - two metal endplates and a plastic inlay, as illustrated below:
The endplates have a patented central keel and small spikes for initial fixation to the vertebrae, and a plasma sprayed titanium coating on all bone contacting surfaces to promote bony integration. The ProDisc-L implant materials have historically been used in hip and knee replacements and have been used in spinal arthroplasty procedures for two decades.
The ProDisc-L implant is available in a variety of sizes to allow surgeons to accurately match the patient's anatomy.
