What this Trial Is About
Degenerative spine conditions are common in older adults and can cause significant health problems. When treatments like physiotherapy and pain medications don’t work, surgery may be needed. This research focuses on a newer surgical method called unilateral biportal endoscopy (UBE) for lumbar decompression and aims to evaluate spinal stability after this procedure, especially since traditional surgeries sometimes lead to spine instability. The study involves patients aged 50 and older undergoing lumbar decompression surgery using the UBE technique. Researchers will assess spinal stability by performing dynamic X-rays three months after surgery. These X-rays will measure abnormal spine movement to determine if UBE surgery preserves spinal stability and potentially reduces the need for spinal fusion surgeries. Participants will have dynamic radiography before surgery and again three months afterward to check for spine movement and stability. The study will also track pain, disability, complications, and vertebral mobility at three months. The overall goal is to understand how well spinal stability is maintained after UBE surgery, with follow-up lasting at least three months post-operation.
