Radiographic changes following anterior cervical fusion

Area of Science:

• Orthopedics
• Neurosurgery
• Spinal Surgery

Background:

• Cervical spondylosis is a common degenerative condition.
• Anterior cervical fusion is a surgical treatment option.
• Adjacent segment disease is a potential complication.

Purpose of the Study:

• To evaluate long-term radiographic changes after anterior cervical fusion.
• To assess the incidence and location of degenerative changes adjacent to fused segments.

Main Methods:

• Retrospective review of nine patients.
• Comparison of preoperative cervical spine films with radiographs 7-15 years post-fusion.
• Radiographic assessment for degenerative changes.

Main Results:

• Eight of nine patients showed increased degenerative disease.
• Degeneration primarily occurred below the fusion level.
• Degeneration was also observed above and below the fusion in some cases.

Conclusions:

• Anterior cervical fusion may be associated with accelerated adjacent segment degeneration.
• Altered biomechanical forces or natural disease progression may contribute to these changes.
• Further research is needed to determine the exact cause.
