New keyhole surgery could ease neck pain without big incisions
NCT ID NCT06886802
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new, less invasive surgery called Posterior Uniportal Endoscopic Cervical Decompression for people with cervical spinal stenosis—a condition that pinches nerves in the neck, causing pain, numbness, or weakness. The surgery uses a small incision and a tiny camera to relieve pressure on the spine. Researchers will track 50 patients in Mexico over 12 months to see if the procedure improves nerve function and reduces disability, with the goal of offering a safer alternative to traditional open surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Posterior Uniportal Endoscopic Cervical Decompression (minimally invasive surgical procedure)
- What this could lead to
- If successful, this could offer a safer, less painful surgical option for cervical spinal stenosis, leading to quicker recovery and fewer complications than traditional surgery.
- What could go wrong
- This is a small, early-stage study with only 50 participants, so results may not apply to everyone. The procedure is still experimental and may not be better than standard surgery.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
• Patients with cervical spinal stenosis who continue to experience symptoms despite receiving complete conservative management for at least 3 months and who have chosen to undergo posterior uniportal endoscopic cervical decompression will be recruited consecutively. Recruitment will take place at the following healthcare centers: * Centro Médico Zambrano-Hellion, TecSalud (San Pedro Garza García, N.L.) and Clínica Cuauhtémoc y Famosa (Monterrey, N.L.) Patients will be recruited by Dr. Mario Benvenutti Regato, a neurosurgery specialist with over 7 years of experience performing endoscopic spine surgery. * Centro Médico Nacional Siglo XXI (Mexico City) Patients will be recruited by Dr. Félix Domínguez Cortinas, a neurosurgery specialist with over 10 years of experience performing endoscopic spine surgery. * Hospital Ángeles Tijuana (Tijuana, B.C.) Patients will be recruited by Dr. Alfonso García Chávez, a specialist in traumatology and orthopedics with over 10 years of experience perfor
