Inclusion criteria
Inclusion criteria: 1. Clear diagnosis of lumbar spinal stenosis; 2. Clinical symptoms include intermittent claudication, leg pain or numbness, consistent with CT and MRI features; 3. Non-surgical treatment >= 3 months with no significant symptom relief or progressive worsening; 4. Meets the indications for UBE technique and surgical treatment; 5. Suitable anatomical structure: no severe variation in local lumbar anatomy, appropriate for UBE surgical operation; 6.

Surgical contraindications: Presence of severe coagulation disorders, active infections, malignant tumors, or severe cardiopulmonary dysfunction (such as NYHA heart function class = III), and other systemic surgical contraindications; 2. Spinal structural abnormalities: Presence of severe scoliosis, lumbar spondylolisthesis (grade II or above), or spinal fractures requiring open reduction; 3. Previous surgical history: History of open surgery or internal fixation implantation in the same lumbar segment (which may affect navigation positioning or UBE operation); 4.
