Disc replacement using Pro-Disc C versus fusion: a prospective randomised and controlled radiographic and clinical
Summary
Artificial disc replacement preserves cervical spine motion better than anterior cervical discectomy and fusion (ACDF). Both treatments reduce pain, but disc prostheses maintain more segmental motion in the first six months post-surgery.
Area of Science:
- Orthopedic surgery
- Spinal biomechanics
- Degenerative disc disease research
Background:
- Anterior cervical discectomy and fusion (ACDF) is standard for cervical degenerative disc disease.
- ACDF can lead to adjacent segment degeneration.
- Dynamic stabilization, including artificial disc replacement, aims to preserve motion.
Purpose of the Study:
- To analyze cervical spine segmental motion after artificial disc replacement.
- To compare motion and clinical outcomes of disc prostheses versus ACDF.
Main Methods:
- Prospective controlled study with 25 patients (disc prosthesis vs. ACDF).
- Radiostereometric analysis quantified intervertebral motion at multiple postoperative time points.
- Clinical outcomes assessed using visual analogue scale and neuro-examination.
Main Results:
- Both disc prosthesis and ACDF reduced segmental motion over time.
- ACDF showed a significantly greater loss of segmental motion compared to disc prostheses at 3, 6, 12, and 24 weeks.
- Significant postoperative pain reduction in neck and arm was observed in both groups, with no significant difference.
Conclusions:
- Cervical spine disc prostheses preserve segmental motion in the initial six months post-surgery.
- Early clinical results of disc prostheses are comparable to ACDF.
- Artificial disc replacement shows potential for maintaining spinal biomechanics compared to fusion.

01:27Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
01:23Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
