Prodisc-L: Lumbar intervertebral disc prosthesis
The Prodisc-L implants replace a lumbar intervertebral disc to restore the intervertebral disc height and maintain segmental movement.
What is the clinical problem?
Vertebral fusion is often used as the standard therapy for the surgical treatment of degenerative disc diseases in the lumbar spine. This procedure is successful in many patients but leads to the loss of mobility and flexibility in the operated segment.
The Prodisc L maintains the mobility between the vertebrae and in the operated segment. In addition, the adjacent segments are exposed to a lower load compared to fusion.
How does Prodisc L work?
The Prodisc L consists of a cranial and caudal implant endplate. The inlay is made of ultra high molecular weight polyethylene. In order to optimally adapt the lordosis, the endplates are available with different lordotic angles. The ball and socket joint principle of the prosthesis enables a physiological range of motion for flexion / extension, rotation and side inclination. To insert the implant, the intervertebral disc is removed via a ventral access and the segment is mobilized. To obtain optimal primary stability, a groove for the keel of the prosthesis is chiselled. The endplates are implanted and the inlay is inserted between the two endplates.
Results Prodisc L
With over 30 years of clinical experience and more than 400 studies, Prodisc L is one of the best documented lumbar disc prostheses. The results show a high patient satisfaction, reduced pain and a reduced degeneration of adjacent segments compared to the fusion.
