Artificial cervical disc replacement for cervical disc herniation

  Artificial cervical disc replacement is now widely performed in clinical practice as a nonfusion technique, with the initial goal of preserving the mobility of the segment and avoiding stress concentrations in adjacent segments that can lead to accelerated degeneration.  It also reduces excessive stripping of the anterior fascia and cervical longus muscle and interference with adjacent segments. However, strict indications are required and not all patients are suitable for this technique. In some cases, single-segment decompression fusion should be preferred. Patients with instability of the segment, degenerative compression tissue ossification, severe stenosis of the articular eminence, bony spinal stenosis, severe osteoporosis, age over 55 years, spinal trauma, and tumors are contraindications to this technique.  At present, the complications of disc disuse and loss of mobility due to heterotopic ossification, and prosthesis displacement and revision have gradually attracted attention.
