Lumbar spinal stenosis refers to the narrowing of the spinal canal in the lumbar spine causing compression over spinal cord and nerves. It is the most prevalent of leg pain and neurogenic claudication symptom.
The most common cause of lumbar spine stenosis is the age-related degeneration in the joints, disc and hyperthrophy of ligament flavum in the lumbar spine.
Symptoms -Pain, weakness, and numbness in the legs and buttocks
 Loss of sensation in the feet
 Loss of bladder/bowel function
 Claudication- difficulty in walking
Daignosis – It includes detailed physical examination of the patient with looking for signs of spinal stenosis, such as loss of sensation, weakness, and abnormal reflexes.
The imaging test may be require –
 X-rays of your lumbar spine. These may show bone growths called spurs that push on spinal nerves and/or narrowing of the spinal canal.
 CT scan or MRI scan can give a more detailed information of spinal canal and neural structures and bone.

When should I consult to doctor?
Consult your doctor if you have:
 Loss of bowel or bladder control
 Severe or increasing numbness between your legs, inner thighs, or back of your legs
 Severe pain and weakness that spreads into one or both legs, making it hard to walk or get out of a chair.
Treatment –
Conservative therapy – It includes certain Medication and physical therapy including back muscles stretching and strenghtening excercises. In addition to that,
the therapies may also include massage, chiropractic practices, and acupuncture.
Surgical option-Surgery is recommended to those patients who don’t respond to conservative treatment and medications.There are different types of spinalsurgeries available, and depending on case to case basis, a surgeon will help to determine what procedure might be appropriate for the patient.
A patient may be considered a candidate for surgery if:
 Back and leg pain limits normal activity or impairs quality of life;
 Progressive neurological deficits develop (leg weakness, foot drop, numbness in the limb);
 Loss of normal bowel and/or bladder functions;
 Difficulty standing or walking;
 Medications and physical therapy are not effective;


Surgical treatments involve the removal of bone spurs with removal of hypertrophied ligament flavum and widening the space between vertebrae. The most common
surgery for lumbar canal stenosis is decompression surgery(laminectomy), in which the laminae is removed to widen the spinal canal with or without removing the disc
and fixing the spine with screws. The fixation and decompression surgery is done through various approaches like Transforaminal Lumbar Interbody Fusion (TLIF),
ANTERIOR lUMBAR INTERBODY FUSION( ALIF ), Posterior Lumbar Interbody Fusion (PLIF), Posterolateral Fusion, and Instrumented Fusion(PLF).
