Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: 1.Age >=18 years; 2.Definitive diagnosis of lumbar spinal stenosis with failure of standardized conservative treatment and remaining surgical indications; 3.Preoperative magnetic resonance imaging (MRI) and computed tomography (CT) findings consistent with clinical symptoms and signs; 4.Undergoing unilateral bilateral endoscopic lumbar decompression surgery (UBELD); 5.Postoperative follow-up duration of no less than 3 months with complete clinical data, imaging data, and follow-up records.
Exclusion criteria
Exclusion criteria: 1.Patients with grade III or higher pars interarticularis fissure-related spondylolisthesis, coronal Cobb angle =20°, or other significant lumbar instability; 2.Previous lumbar surgery at the same segment requiring revision; 3.Concurrent severe spinal conditions such as lumbar fractures, infections, tumors, or ankylosing spondylitis; 4.Associated neurodegenerative disorders including Alzheimer's disease or Parkinson's disease; 5.Inadequate follow-up or incomplete clinical data. According to the original study, during outcome evaluation, cases of structural failure due to recurrent stenosis or insufficient decompression, as well as those failing to meet minimal clinically important differences (MCID) due to preoperative overly low objective disability index (ODI), were excluded from the slow functional improvement assessment to minimize bias and enhance study population homogeneity.
