Summary

This study tests a minimally invasive surgery called ULBLD for people with lumbar spinal stenosis—a condition that narrows the spine and causes pain or numbness. The surgery uses a small incision and a camera to relieve pressure on nerves. Researchers will track 78 patients in Mexico for 12 months to see if it improves disability, pain, and nerve function compared to their pre-surgery state.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
unilateral laminotomy with bilateral lumbar decompression (ULBLD) using endoscopic uniportal technique
What this could lead to
If successful, this could offer a less painful, faster-recovery surgical option for people with lumbar spinal stenosis.
What could go wrong
This is a small, early-stage case series without a comparison group, so results may not apply to everyone. Surgery always carries risks like infection or nerve damage.

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 lumbar spinal stenosis who continue to experience symptoms despite receiving complete conservative management for at least 3 months and who have chosen to undergo ULBLD using endoscopic uniportal technique 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
