Cervical Disc Arthroplasty (CDA)

Cervical disc arthroplasty (CDA) is mostly used for cervical radiculopathy symptoms mainly caused by soft disc herniation, with segments still having mobility and without obvious instability or severe degeneration. If conservative treatment is ineffective or there is a risk of neurological damage, a specialist can evaluate whether it is suitable. The decision depends on factors such as intervertebral height, vertebral alignment, facet joints, and bone density shown on imaging, and considers device size matching.
