Cervical arthroplasty results similar in patients with myelopathy, radiculopathy
Cervical arthroplasty produced similar results in patients with cervical spondylotic myelopathy or radiculopathy caused by degenerative disc disease at 3-year follow-up, according to study findings.
Researchers retrospectively analyzed 151 patients with cervical spondylotic myelopathy (CSM) or radiculopathy caused by degenerative disc disease who underwent single- or double-level cervical arthroplasty in the study. They reviewed patients’ radiographic studies and clinical outcome measurements, which included VAS neck and arm pain, Japanese Orthopaedic Association (JOA) and Neck Disability Index (NDI) scores.
Among the patients involved in the study, 72 myelopathy patients and 53 radiculopathy patients had at least 24 months of follow-up data; mean duration of follow-up was 36.4 months.
VAS neck and arm, JOA and NDI scores showed significant improvement after surgery in both groups, according to the researchers.
There were no significant differences observed between the groups with regard to the retention of spinal motion on radiographic evaluation. Additionally, no secondary surgeries were reported in either group at a mean of more than 3 years after surgery.
The researchers concluded that cervical arthroplasty is an option for patients who have CSM caused by degenerative disc disease and require anterior surgery.
