The Treatment

During the total disc replacement procedure, the diseased intervertebral disc is removed and replaced with a motion preserving Prodisc-Oblique implant. The Prodisc-O total disc replacement surgery is intended to:

 

–	Remove the diseased disc
–	Restore normal disc height
–	Significantly reduce discogenic pain
–	Preserve motion in the affected vertebral segment
–	Improve patient function

The Design

The Prodisc-O implant design is a further development of the Prodisc-L implant and is also based on a ball and socket principle. Except for the oblique keel, designed for the 45° antero-lateral approach, the shape and the biokenetics remain identical. The reason for the oblique approach is less need to mobilize the vessels within the Levels L1-L5. The Prodisc-O implant consists of three implant components – two metal endplates and a plastic inlay, as illustrated below:

The endplates have a patented 45° positioned keel for initial fixation to the vertebrae, and a plasma sprayed titanium coating on all bone-contacting surfaces to promote bony on growth. The Prodisc-O implant materials have historically been used in total joint replacement and have been used in spinal arthroplasty procedures for two decades.

 

The Prodisc-O implant is available in a variety of sizes to allow surgeons to accurately match the patient’s anatomy.

 

The Prodisc-O total disc replacement has been determined to be safe and effective in the treatment of degenerative disc disease (DDD) in the lower back. The Prodisc-O total disc replacement is clinically proven to maintain motion in the spine.
