Cervical spine instability in rheumatoid arthritis

Area of Science:

• Orthopedics
• Rheumatology
• Neurosurgery

Background:

• Rheumatoid arthritis (RA) frequently impacts the cervical spine (CS), affecting over half of patients.
• RA can lead to ligamentous degeneration, instability, and subluxation in the CS.
• Cervical spine involvement in RA may cause asymptomatic or unrecognized spinal cord compression, risking severe neurological deficits or death.

Purpose of the Study:

• To highlight the diagnostic and therapeutic challenges of cervical spine involvement in RA.
• To emphasize the importance of early surgical intervention in preventing neurological deterioration.
• To discuss the optimal timing for prophylactic stabilization in RA patients with radiographic instability.

Main Methods:

• Review of current understanding of RA's impact on the cervical spine.
• Analysis of surgical goals and recent advancements in techniques.
• Discussion on the timing of surgical intervention based on clinical and radiographic evidence.

Main Results:

• Advances in surgical techniques and preoperative evaluation have improved safety and efficacy.
• Early surgical stabilization before neurological deficits offers better outcomes.
• The optimal timing for prophylactic stabilization in asymptomatic patients remains poorly defined.

Conclusions:

• Cervical spine RA requires careful diagnosis and management due to potentially severe consequences.
• Surgical intervention aims to stabilize the upper cervical spine, prevent neurological damage, and improve function.
• Further definition is needed regarding the timing of prophylactic surgery for patients with radiographic instability but no current neurological deficits.
