Summary
Cervical disc arthroplasty using the ProDisc-C demonstrated significant improvements in pain and function for cervical spondylosis patients. This study found no device-related complications or adjacent segment fusions after one year.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Cervical spondylosis is a degenerative condition affecting the cervical spine.
- Anterior cervical decompression and total-disc replacement are emerging treatments.
- The ProDisc-C is a specific device for cervical disc arthroplasty.
Purpose of the Study:
- To prospectively evaluate the safety and efficacy of the ProDisc-C for cervical arthroplasty.
- To assess outcomes in patients with symptomatic cervical spondylosis.
Main Methods:
- Prospective study of 16 patients undergoing anterior cervical discectomy and ProDisc-C arthroplasty.
- Performed 12 single-level and 4 two-level procedures (20 prostheses).
- Assessed pain, disability, and radiographic outcomes at multiple time points up to 12 months.
Main Results:
- Significant improvements in neck and arm pain and disability scores were observed by 3 months and sustained at 1 year.
- No additional fusion surgeries were required.
- Maintained disc motion (4-12 degrees) and reported no surgery- or device-related complications.
Conclusions:
- Preliminary results show ProDisc-C arthroplasty significantly improves pain and function in cervical spondylosis.
- No spontaneous fusions occurred at the surgical or adjacent levels.
- Long-term studies are needed for definitive recommendations.
