What Is Spinal Stenosis?
Spinal stenosis means the spaces inside the spine have narrowed. The old site described this as pressure on the spinal cord or nerves. In the lower back, stenosis often affects walking tolerance. In the neck, stenosis can affect both nerve roots and the spinal cord.
Why It Happens
- Arthritis and bone spurs: Facet joints enlarge and reduce nerve space.
- Thickened ligaments: Ligamentum flavum can buckle into the canal.
- Disc degeneration or herniation: Disc changes narrow the canal or foramina.
- Spondylolisthesis: A slipped vertebra can worsen narrowing.
- Congenital narrow canal: Some patients are born with less available space.
Symptoms
Lumbar stenosis can cause low-back pain, buttock pain, leg numbness, cramping, heaviness, or weakness with standing or walking. Cervical stenosis can cause neck pain, arm symptoms, balance problems, or hand clumsiness. Seek urgent care for sudden weakness, bowel or bladder changes, saddle numbness, or rapid balance decline.
Diagnosis
PPSI reviews your symptom pattern, walking tolerance, posture, strength, reflexes, and sensation. MRI is often used to confirm the location and severity of narrowing. X-rays can identify instability, arthritis, and spondylolisthesis. EMG/NCS can help confirm nerve involvement when symptoms overlap with neuropathy.
Treatment Options
Non-surgical care may include flexion-based physical therapy, core and hip strengthening, walking modifications, medication guidance, and activity planning. Image-guided epidural steroid injections or selective nerve-root blocks may reduce nerve inflammation and improve function. Spine surgery consultation is considered for severe stenosis, progressive weakness, myelopathy, or persistent walking limitation despite conservative care.
PPSI Care Path
We focus on what stenosis is preventing you from doing: walking, working, sleeping, or caring for family. The plan may combine pain management, rehabilitation, and surgical review so you understand both short-term relief and long-term options.
Frequently Asked Questions
Why does leaning forward help?
Leaning forward can temporarily open the spinal canal in lumbar stenosis, which is why shopping-cart posture may feel better.
Can stenosis be treated without surgery?
Yes, many patients improve with therapy, injections, medication guidance, and activity changes. Surgery is reserved for selected cases.
Is cervical stenosis more serious?
It can be if the spinal cord is compressed. Balance problems, hand clumsiness, or bladder changes need prompt evaluation.
