L4 and L5 are the last two vertebrae in your back before you hit your tailbone.
To fuse them, the surgeon will physically break the bones and put bone graft over them (bone graft can be from a bone bank or harvested from the patient's ribs or hip bone). When the bone heals, the graft will become part of the vertebrae, making the two vertebrae one solid bone.
Because bone takes about six months to heal, the surgeon will secure the fusion with titanium rods and screws to hold it in place until the fusion takes.
After the bone is fused, there is no need for the metal hardware. However, because the metal hardware is harmless, it won't be removed unless there are complications.

Causes of spinal dissication?
what is mutilevel dissication. l3 andl4 l4 and l5 l5 and s1
What is posterior disc herniation of the L5 S1 impinging on the anterior aspect of the spinal cord?
Posterior means "rear" - Anterior means "front. What the report is saying is that the L5/S1 disk is herniated at the back of the disk (posterior) and is impinging on the front of the spinal cord as a result. This is very common for that particular disk, as well as the L4/5 disk.
What is posterior disc herniation of the L5-S1 impinging on the anterior aspect of the spinal cord?
Posterior means "rear" - Anterior means "front. What the report is saying is that the L5/S1 disk is herniated at the back of the disk (posterior) and is impinging on the front of the spinal cord as a result. This is very common for that particular disk, as well as the L4/5 disk.
What is the spinal root of the tibial nerve?
L4,l5,s1,s2,s3
What does L4-5 Annular bulge touching thecal sac resulting in moderate central stenosis with bilateral centrally located L5 neural abutment mean?
There's a bulge pushing through the ring holding the vertebral disk between L4 and L5. The bulge is narrowing the opening for the spinal cord somewhat, and is also touching both sides of the nerves coming off the spinal cord at L5.
Sciatica reflects neuritis in a nerve from the?
Nerve root outlet of the spinal cord, most often between L4-L5 or L5-S1.
What does diffuse disc bulge at L4-L5 causing mild narrowing of bilateral foramina indicative of?
What the radiology report indicates is that you've got a herniated disk at the L4/5 vertebrae, which is pressing forward into the spinal cord passageway. The foramen is the narrow passage in the vertebrae where the spinal cord runs through.
What is grade 1 degenerative anterolisthesis of L4 on L5. Degenerative disc space narrowing and facet arthrosis L4-L5 and L5-S1 and resultant canal stenosis and neural foraminal narrowing at L4-L5 and?
What all can they do for it because I'm in pain all the time. Plus I have a buling disk. I'm doing therapy and its not helping.
What are L4 and L5?
They could be several things. Many different systems use an alphanumerical combination to record and file thinsg, and the terms L4 and L5 can refer to some specific things depending on what field you work in. Examples commonly used are the lumbar verebrae L4 and L5 in anatomy, and the LaGrangian points L4 and L5 in astronomy. The lumbar vertibrae L4 and L5 are the sciatic region of the back and are the most common area of disk compression failure, leading to chronic sciatica and other lower body nerve compromise.
What does encroachment of the ventral subarachnoid space in the L4-L5 level mean?
Encroachment: Taking up space to which it's not entitled.ventral: belly sidesubarachnoid space: the area just under the membranes surrounding the spineL4-L5: the space between the fourth and fifth lumbar vertebrae.So, to sum up, something (probably a herniated disk?) is taking up space on the belly side of the spinal cord between L4 and L5. It's not pressing the cord, but it is crowding the space between the spinal cord and the surrounding membrane.
Where in the vertebrae is a spinal tap done?
In rare instances, such as a spinal fluid blockage in the middle of the back, a doctor may perform a spinal tap in the neck.
What is Nerve root clumping at L4 L5 and L5 S1?
Nerve root clumping is usually indicative of arachnoiditis, a painful, progressive spinal condition. Please research arachnoiditis.
