Inclusion criteria

Inclusion criteria: 1. Age > 75 years, regardless of gender. 2. Confirmed diagnosis of single-level or two-level lumbar spinal stenosis (central canal or lateral recess stenosis) by MRI or CT imaging. 3. Clinical presentation of typical neurogenic intermittent claudication, with or without neurological deficits in the lower extremities (pain, numbness, muscle weakness). 4. Symptoms significantly affecting quality of life (ODI > 40%) after failure of at least 3 months of rigorous conservative treatment. 5. American Society of Anesthesiologists (ASA) classification < III, and deemed able to tolerate endoscopic surgery after multidisciplinary evaluation. 6. Voluntary participation in this study and provision of signed informed consent.

Exclusion criteria

Exclusion criteria: 1. Presence of lumbar spondylolisthesis > Grade II, or evidence of significant lumbar instability confirmed by dynamic radiographs. 2. History of prior lumbar surgery at the same spinal segment (revision surgery). 3. Spinal stenosis caused by non-degenerative conditions (e.g., tumor, tuberculosis, fracture, ankylosing spondylitis). 4. Presence of severe spinal deformity (Cobb angle > 20°). 5. Presence of severe mental illness or cognitive impairment (e.g., severe Alzheimer's disease) that would preclude cooperation with scale assessments. 6. Presence of severe coagulation dysfunction or inability to discontinue anticoagulant medication.
