When spinal stenosis causes nerve or spinal cord compression, surgery may be recommended if symptoms don’t improve with nonsurgical care. Two procedures patients often hear about are laminectomy and laminoplasty.

What they have in common

Both procedures:

relieve pressure by creating more space in the spinal canal
are commonly used for stenosis-related symptoms
may be paired with other procedures when needed

What is a Laminectomy?

A laminectomy removes part (or all) of the lamina, the bony “roof” at the back of the spinal canal, to relieve pressure on nerves or the spinal cord.

Key features:

removes bone to decompress
can be done in the cervical or lumbar spine
sometimes paired with fusion if stability is a concern

What is a Laminoplasty?

A laminoplasty reshapes and repositions the lamina (often like a “hinge”) to expand the spinal canal without fully removing the bone. It is most commonly performed in the cervical spine.

Key features:

expands the canal while preserving more anatomy
typically used for cervical spinal cord compression
may help preserve motion compared with fusion in select cases

Key differences at a glance

Laminectomy

removes the lamina
may be more common in lumbar stenosis
may require fusion if instability is present

Laminoplasty

repositions the lamina (does not fully remove it)
most commonly used in the cervical spine
often used for spinal cord compression (myelopathy)

When one may be preferred

Laminectomy may be recommended when:

stenosis is in the lumbar spine
there is nerve root compression causing leg symptoms
decompression is needed and stability is acceptable (or fusion is planned)

Laminoplasty may be considered when:

stenosis is in the cervical spine
spinal cord compression is present
preserving motion is a goal in appropriate patients

Recovery differences (general)

Both require gradual activity progression and sometimes physical therapy
Laminoplasty is commonly a cervical procedure; recovery details depend on cord compression severity
Laminectomy recovery varies widely by location and whether fusion is included
