Case series reports on a new endoscopic technique showing improved outcomes in cervical radiculopathy, suggesting a promising surgical option.

This study aims to evaluate the feasibility and outcomes of uni-portal non-coaxial spinal endoscopic surgery via a crossing midline approach for cervical radiculopathy.
Conducted a retrospective, single-center study on four patients with cervical radiculopathy due to bony foraminal stenosis.
The surgical procedure involved removal of V-point osteophytes, excision of herniated nucleus pulposus, and preservation of the lateral bony structure of the facet joint.
Patients were followed for outcomes such as Visual Analogue Scale (VAS) and Japanese Orthopaedic Association (JOA) scores.
Mean operative time was 168.5 minutes with blood loss averaging 15 mL.
VAS scores improved by an average of 1 point, while JOA scores improved by 16 points at 1 month postoperatively.
All four incisions healed within 2 weeks without complications at the 6-month follow-up.
