Short-term outcomes for cervical disc replacement positive
Results of a recently published study demonstrated Mobi-C artificial disc replacement surgery had good clinical results; however, more data and longer follow-up times are needed to determine what long-term effects the surgery may have on patients with cervical spondylosis.
Researchers conducted a retrospective study of 65 patients who underwent Mobi-C artificial disc Mobi-C artificial disc (LDR) replacement surgery for cervical spondylosis at 10 centers. The average age of the patients was 44.8 years. Eight patients had C3–C4 replacement, 24 had C4–C5 replacement, 26 had C5–C6 replacement and seven had C6–C7 replacement.
The researchers reviewed the clinical and radiographic data from before surgery and for 7 days, and 1, 3, 6, 12, 24 and 36 months postoperatively. They also assessed clinical and neurological outcomes using the Japanese Orthopaedic Association (JOA) score, VAS, Neck Disability Index (NDI) scores and Odom’s criteria.
According to study data, patients saw significant improvements in JOA, NDI and VAS scores by 36 months postoperatively. The average preoperative JOA score was 11.1, which improved to 14.63 at 36 months postoperatively. Average preoperative VAS score was 6.89, which improved to 2 at 3 months postoperatively. Average preoperative NDI score was 36.93, which improved to 19.33 by 36 months postoperatively. Finally, Odom’s criteria evaluation showed that at 24 months, 31 patients were rated as excellent, 23 were rated as good, 11 were rated as fair and none were rated as poor. By 36 months, 34, 25, six and none of the patients were rated as excellent, good, fair and poor, respectively.
Additionally, intervertebral height of the treated segment was restored postoperatively, according to the researchers. – by Robert Linnehan
