Circumferential Decompression Technique of Posterior Endoscopic Cervical Foraminotomy

Area of Science:

• Neurosurgery
• Spinal Surgery
• Minimally Invasive Procedures

Background:

• Cervical osseous foraminal stenosis (COFS) arises from uncinate process and facet hyperostosis.
• The optimal surgical treatment for COFS is currently debated.
• Radiculopathy is a common symptom of COFS.

Purpose of the Study:

• To evaluate the safety and efficacy of posterior endoscopic cervical foraminotomy using the circumferential decompression technique for COFS.
• To assess the impact of this technique on patient-reported outcomes and cervical spine stability.

Main Methods:

• 24 patients with COFS and radiculopathy underwent posterior endoscopic cervical foraminotomy.
• Outcomes were assessed using the Neck Disability Index (NDI), Visual Analogue Scale (VAS), and modified MacNab criteria.
• Cervical spine stability was evaluated by measuring intervertebral range of motion (ROM) and slippage distance.

Main Results:

• Significant improvements in NDI and VAS scores for arm/neck pain were observed postoperatively.
• High patient satisfaction rates were reported (91.7% by day 3, 100% at final follow-up).
• No significant changes in intervertebral ROM or slippage distance indicated preserved cervical spine stability.

Conclusions:

• Posterior endoscopic cervical foraminotomy with circumferential decompression is a safe and effective treatment for COFS.
• The procedure successfully alleviates radiculopathy symptoms.
• Cervical spine stability and physiological mobility are preserved after surgery.
