Adjacent Segment Pathology after Anterior Cervical Fusion

Area of Science:

• Spine surgery
• Orthopedics
• Neurosurgery

Background:

• Anterior cervical fusion is a standard treatment for cervical spine conditions.
• Adjacent segment pathology (ASP) is a significant long-term complication following cervical fusion.
• Increased patient longevity and motion preservation technologies are driving more interest in ASP.

Purpose of the Study:

• To explore the multifactorial etiology of adjacent segment pathology (ASP).
• To understand the scope and nature of ASP after anterior cervical fusion.
• To identify factors contributing to ASP development.

Main Methods:

• Review of existing literature on cervical spine surgery and adjacent segment pathology.
• Analysis of biomechanical factors, surgical techniques, and patient-related variables.
• Discussion of the natural history of cervical disc disease in relation to ASP.

Main Results:

• ASP development is multifactorial, involving altered biomechanics and surgical factors.
• Patient-related factors like age, smoking, and gender may influence ASP.
• Postoperative alignment and surgical technique are potential contributors to ASP.

Conclusions:

• The etiology of adjacent segment pathology (ASP) is complex and not fully understood.
• Spine surgeons must minimize soft tissue disruption and optimize surgical technique to reduce ASP risk.
• Careful surgical planning and execution are crucial for long-term patient outcomes after anterior cervical fusion.
