[Preliminary clinical study on artificial cervical disc replacement by Mobi-C prosthesis]

Area of Science:

• Spine surgery
• Orthopedic biomechanics
• Degenerative cervical spine disease

Background:

• Anterior cervical discectomy and fusion (ACDF) is a common treatment for cervical disc disease.
• Artificial disc replacement (ADR) aims to preserve motion at the operated segment.
• The Mobi-C prosthesis is a specific implant used for ADR in the cervical spine.

Purpose of the Study:

• To evaluate the clinical application and short-term outcomes of the Mobi-C prosthesis in patients undergoing anterior cervical discectomy and artificial disc replacement (ADR).

Main Methods:

• A prospective study of 20 patients with degenerative cervical disease treated with Mobi-C prosthesis.
• Patients underwent anterior discectomy and ADR, with 25 prostheses implanted across various cervical segments.
• Clinical outcomes were assessed using cervical range of motion (ROM), the Cervical Outcome Assessment (COA) score, Neck Disability Index (NDI), and Visual Analogue Scale (VAS) score.

Main Results:

• No perioperative complications or heterotopic ossification were observed.
• Cervical ROM at the operated segment remained stable post-surgery.
• Significant improvements were noted in COA scores (indicating better spinal cord function), VAS scores (pain reduction), and NDI scores (reduced disability).

Conclusions:

• The Mobi-C prosthesis shows a satisfactory short-term curative effect for anterior cervical discectomy and ADR.
• This ADR technique effectively improves neurological function, reduces pain, and enhances the quality of life for patients with degenerative cervical disease.
