a

Lumbar Laminectomy and Fusion Presented by Spine Nevada, Reno Spine Surgeons and Spine Center

a lumbar laminectomy infusion is a

procedure used to decompress and

stabilize the lumbar spine this relieves

pain and weakness caused by narrowing of

the spinal canal a condition called

spinal stenosis spinal stenosis is

defined by the excessive bone and

ligament growth of the spinal canal

this results in narrowing which

compresses the nerve roots leading to

shooting pain down the back and legs and

possible numbness and weakness in some

cases the bulging of a herniated disc

can contribute to the condition of

spinal stenosis in a laminectomy the

bony arch called the lamina is

completely removed to alleviate the

pinched nerve roots using fluoroscopy a

special type of x-ray the treatment

region is located and an incision is

made on the patient's lower back in an

open laminectomy the spinous process is

exposed by dissecting the muscle on both

sides of the spine a self-retaining

retractor is placed and access to both

sides of the lamina is achieved this

procedure results in more tissue trauma

than the alternative minimally invasive

bilateral laminotomy

the spinous process the part of the

vertebra that protrudes down the back of

your spine is first removed to better

access the damaged parts of the lamina

to achieve nerve root decompression the

surgeons at spine Nevada will thin out

the lamina on both sides of the spine

using high speed drills special biting

instruments are then used to extract

pieces of the thickened ligament the

surgeon tests the nerve roots to check

if pinching still occurs bone spurs

around the foramina openings where the

nerve roots exit the spine may be

cleared in order to achieve full nerve

root decompression graft material is

laid on the transverse processes and

facet joints lateral mask screws are

then placed on either side of the

vertebra and a rod system is secured to

stabilize the spine as it heals over

time the graft material will fuse with

the vertebral tissue above and below

forming a bone mass called a fusion the

wound is closed with absorbable sutures

and a dressing is applied at spine

Nevada this procedure is generally

performed as an outpatient procedure
