PCM Artificial Disc
A normal cervical disc can rotate forward, backward , left, right and side-to-side. The PCM Artificial Cervical disc achieves To prepare for insertion of the PCM Artificial disc, the diseased disc must be completely removed. After disc removal, the extraction of tissue fragments and other material that could be causing nerve compression follows. To insure the PCM device will fit properly, the designated area is shaped so that the edges of the device can be correctly seated. The process takes approximately two hours and the patient is ready for discharge the next day.

The cervical (neck) portion of the spine is joined by seven bones called vertebrae. Between each vertebra lies a sponge-like tissue called a disc. The disc stabilize the neck allowing the seven vertebrae to stick together during movement. With advancing age, the disc may break down causing the bones in the neck to slip or become unstable. Heavy labor or stress on the neck may can also cause disc tissue to become weak and bulge out from its original position in the neck. Symptoms such as numbness, tingling sensations, or a feeling of weakness in the neck and shoulders area follow a herniated (bulging) disc. In non-severe cases rest and conventional medications maybe all that is needed. If surgery is necessary, the faulty disc is usually completely removed and bone material is inserted in its place. A special plate and screws secure the bone material. With time the bone material fuses together and pain in the affected area diminishes. This method limits the range of motion in the neck because the disc responsible for movement in the problem area has been replaced with bone. The PCM Artificial Cervical Disc has been developed to preserve the range of motion in the neck by way of emulating natural cervical disc functions.
similar types of movement by utilizing two (Cobalt Chrome) endplates and a Polyethylene spacer. The spacer, or the area between the two endplates, gives the ball-in-socket effect, which allows the upper half to slide forward and backward relative to the lower.
