Researchers examined 21 patients who underwent 27 total disc arthroplasties using Medtronic Sofamor Danek’s Bryan cervical disc after anterior cervical discectomy. After an eight-year postoperative review, 19 of the patients were able to perform daily tasks without limitations.
Additionally, 20 of the patients reported fair to excellent outcomes according to the Odom criteria and 78 percent of the operated segments were mobile. The functional prostheses moved an average of 10.6 degrees, similar to the range of movement of the adjacent non-operative segments.
In 48 percent of the patients, herniated ossification was evident in the operated segments and restricted movement of the prosthesis was reported in nine cases. Five of the six patients who received bilevel arthroplasties developed heterotopic ossification. There were no reported cases of migration, subsidence, loosening or wear of the prosthetic.
