Conditions
Summary
A single-center, prospective cohort trial aims to provide stronger evidence regarding the impact of degenerative spondylolisthesis on the clinical outcome of unilateral biportal endoscopy for lumbar spinal stenosis
Eligibility
Min Age: 50 YearsMax Age: 80 Years
Inclusion Criteria5
- Age range: 50-80 years
- Diagnosis of LSS affecting 1-2 vertebral levels
- Predominant manifestation of neurogenic intermittent claudication, with ineffective conservative treatment for at least 3 months

- Willingness to participate in the study and complete follow-up assessments.
Exclusion Criteria7
- Diagnosis of isthmic lumbar spondylolisthesis or lumbar DS of grade ≥II
- Evidence of instability at the affected vertebral level (intervertebral angle change \> 15° and/or vertebral translation ≥ 4.5 mm in standing flexion-extension radiographs of the lumbar spine)
- History of prior surgery at the affected vertebral level
- Presence of scoliosis with a Cobb angle \>20º
- Presence of other conditions affecting the lumbar spine (infection, tumor, fracture, neurological diseases, and others)
- Medical disorders that preclude surgical tolerance
