Artificial Disc Replacement for Ruptured Disc

An artificial disc replacement for ruptured disc is an increasingly popular back surgery for those with this type of condition as it allows the flexibility and motion of the spine to be maintained.  This is in stark contrast to the stiffness that occurs with spinal fusion procedures and also reduces the risk of placing extra stress on surrounding tissues and discs.  Adjacent segment syndrome and spinal fracture is , therefore, less of a risk and further surgery is also less likely.  A  number of different technologies are in use in the US, and some surgeons have been using the technique in Europe since the 1990s.  Unfortunately, the documentation of the surgeries conducted many years ago fails to provide sufficient detail to allow long-term results to be clarified.  It is thought, due to laboratory testing, the the artificial discs have a lifespan sufficient to remain in place and functional even in those having the back surgery in their thirties or forties.  However, it remains a possibility that the prosthesis will need replacing.

Various artificial disc models include the Prodisc-C™ by Synthes Spine Solutions and the PCM cervical artificial disc by Cervitech, both of which have undergone clinical trials to assess their risks and benefits.  The Bryan™ Cervical Disc Prosthesis by Medtronic Sofamor Danek is a different type of artificial disk made from metal and polyurethane like the others but designed to maintain motion and act as a shock absorber.  Clinical trials of the Bryan model found nearly all patients to have excellent or good outcomes at their last follow-up.  The majority of patients had their flexion and extension neck motion maintained, and no significant incidence of subsidence or migration of the devices has been documented.
