Dynamic cervical stabilization: a multicenter study

Area of Science:

• Orthopedic surgery
• Spinal biomechanics
• Degenerative cervical disorders

Background:

• Degenerative cervical disorders necessitate innovative treatments.
• Motion-preserving implants aim to improve patient outcomes.
• The dynamic cervical implant (DCI) represents a novel approach.

Purpose of the Study:

• To validate the clinical concept of the dynamic cervical implant (DCI).
• To analyze the clinical and radiological performance of the DCI.
• To assess the DCI's efficacy in treating degenerative cervical disorders.

Main Methods:

• Prospective clinical study involving 175 patients with degenerative cervical disorders.
• Patients underwent discectomy and DCI implantation, with a 2-year follow-up.
• Clinical outcomes assessed using NDI, SF-12, and VAS; radiological outcomes via ROM and cervical alignment analysis.

Main Results:

• Significant improvements in VAS neck/arm pain, NDI, and SF-12 scores (p < 0.001).
• Slight reduction in ROM at the treated level, with no significant adjacent level changes.
• Six adverse events related to surgery or the device were documented.

Conclusions:

• The DCI demonstrates good clinical outcomes and excellent radiological results.
• The dynamic cervical implant is a safe and efficient treatment option.
• DCI is a viable solution for patients suffering from degenerative cervical disorders.
