Researchers examined 45 patients with cervical disc herniation who received 51 Bryan cervical disc prostheses. Single-level disc procedures were performed in 39 cases and bi-level in six cases.
After an average follow-up of 35 months, patients showed significant improvement in neurological symptoms. The neck disability score was reduced from 43.5 to 28.4 at the final follow up. Range of motion at the implant level was 9.3 degrees postoperatively and no patient experienced a migration of the artificial disc greater than 2 millimeters.
There was some difficulty reported in matching implants for a small group of patients due to the variation of anatomic index for Asian patients.
