About

This study is to evaluate the correlation between muscle atrophy (MA), sagittal alignment, and stenosis degree in patients with lumbar spinal Stenosis (LSS). From existing radiological images, specific radiographic parameters will be extracted. General Information (Age, sex, levels of stenosis, duration of symptoms) will be extracted from patient files.

Enrollment: 165 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Diagnosis of degenerative lumbar spinal stenosis
• Upright standing sagittal plane X-ray of lumbar spine with clear visibility of pelvis sacrum and femoral head
• MRI of the lumbar region with clear visibility of different muscle atrophy grade
• Consent that health related information can be used for research was signed

Exclusion criteria

• Other spinal disease such as severe scoliosis, fracture, spondylolisthesis and ankylosing spondylitis.
• Neuromuscular diseases such as M.Parkinson or multiple sclerosis
• Previous surgery of the spine
