in reply to: Upcoming L5-S1 procedure #36139
Hey doc – a few years ago at a different level I had an L3-4 microdiscectomy, a surgery that introduced an infection that required PICC line antibiotics. You were greatly helpful to me during that time with many answers on the forum. Thank you. The disc at that level eventually so deteriorated and causing me pain (bone on bone almost) that I had a fusion. There have been no other issues at that level.
The plan with the L5-S1 surgery seems to be to remove any extruded disc material, and also to do a procedure to remove part of the bone to allow the nerve more room. I will inquire about a laminotomy vs. laminectomy.
Thank you for the reply!
in reply to: Upcoming L5-S1 procedure #36134UPDATE: reply from surgeon’s PA on similar query, this makes more sense to me now, but would still be good to hear your thoughts based on MRI and proposed plan.
UPDATE from surgeon’s office:
This procedure (Minimally invasive laminectomy) is basically almost the same as the first lower back surgery you had–the Microdiscectomy. It just differs in that we do not remove an extruded disc fragment. We just remove the little portion of the bone that is pinching the nerve. So it is actually a smaller procedure than the Microdiscectomy and you do not have as many postop restrictions. It is outpatient so you will go home the same day. Just no BLT for 2 weeks after surgery then get you into PT. But you can do the elliptical, bike, walk on the treadmill 2 weeks after surgery. You can lift your daughter but I would be careful in the first several days/week after surgery and use proper lifting techniques:)
We would only remove something at the time of the procedure. If it is just a broad-based disc bulge we don’t remove that because we would have to cut a hole in the disc and that could cause more disc material coming out after surgery and having to go back in. When we get down there and if we see any extruded material we will remove that and if there is already a hole in the disc we will interrogate that but we try really hard not to create our own hole in the annulus.
in reply to: Sciatica following L3-4 XLIF?? #35078Thank you! I will follow up in a few weeks after seeing my surgeon for a physical exam.
in reply to: Sciatica following L3-4 XLIF?? #35076Followed up with my surgeon after he read the above results. He basically said there was nothing on the MRI that would be related to an ache or radiculopathy in the low back down to the lower part of my right leg. He said this MRI was probably my best ever. I agree it does sound pretty good. So now I don’t know what to do/think. He said to make an appointment so he could see me in person to help further diagnose.
Could anything obscured by the cage / hardware be causing this?
Otherwise, I guess I have to chalk it up to an irritated and angry nerve unrelated to herniation or compression?
Thank you,
Joshuain reply to: Sciatica following L3-4 XLIF?? #35075Hi doctor, here is the new MRI, any idea based on this what might be causing the back/nerve pain down my leg?
EXAM: MRI LUMBAR SPINE WITHOUT AND WITH CONTRAST
HISTORY: Acute onset low back pain with left lower extremity radiculopathy.
TECHNIQUE: Multiplanar, multi-sequential MRI of the lumbar spine was obtained on a 3T scanner using a standard protocol.
Contrast: 15 mL gadoterate meglumine from a 15 mL vial.
COMPARISON: MRI lumbar spine 1/18/2022.
FINDINGS:
For purposes of this dictation, the last well-formed disc space will be labeled L5-S1.
OSSEOUS STRUCTURES: Patient is status post interval L3-4 discectomy, placement of intervening L3-4 metallic artificial disc and posterior instrumented metallic spinal fusion via left-sided interlocking metallic rod transfixed by left-sided L3 and L4 pedicle fixation screws.
There are no compression fractures.
Redemonstrated, small chronic T11-12 through L2-3 endplate Schmorl’s nodes.
No marrow edema or destructive marrow process.ALIGNMENT: Redemonstrated, anterior grade 1 retrolisthesis L2-3.
SPINAL CORD, CONUS MEDULLARIS AND SPINAL CANAL: Conus medullaris is at T12-L1.
There are no enhancing mass lesion, abnormal signal or abnormal enhancement involving the distal thoracic spinal cord, conus medullaris or cauda equina nerve root sheaths.
There are no intraspinal masses.PARASPINAL AND INTRA-ABDOMINAL SOFT TISSUES: No paraspinal masses.
INCLUDED THORACIC SPINE AND SACRUM: Unremarkable.
DISCS: Mild L2-3 disc space narrowing is redemonstrated.
The following axial levels are imaged and detailed below:
L1-L2: No disc bulging or herniation. No spinal canal or neuroforaminal stenosis.
L2-L3: Uncovering of the disc by spondylolisthesis.
Mild enhancing disc bulging. No spinal stenosis or foraminal narrowing. Stable findings.L3-L4: No disc bulging or herniation. No spinal canal or neuroforaminal stenosis.
L4-L5: No disc bulging or herniation. No spinal canal or neuroforaminal stenosis.
L5-S1: No disc bulging or herniation. No spinal canal or neuroforaminal stenosis.
IMPRESSION:
1. Status post interval L3-4 discectomy, L3-4 metallic artificial disc and left-sided posterior instrumented metallic spinal fusion L3-4.
2. No new disc herniations or spinal stenosis.
3. Degenerative grade 1 retrolisthesis L2-3 with mild disc bulging. Stable.
4. Otherwise no significant interval change.Thank you for the opportunity to participate in the care of this patient.

ANTERIOR
INCISION AND EXPOSURE: Following surgical time-out and radiographic localization, a 4 cm incision was made in the left flank over the L3-4 disc space in a transverse manner. Electrocautery was utilized to achieve hemostasis. Blunt dissection was utilized to dissect through the subcutaneous fat. With great care in the lumbar fascia was incised with Metzenbaum scissors. The external oblique, internal oblique and transversalis musculature was spread bluntly. The transversalis fascia was snipped and the retroperitoneal space was entered. Digital dissection was utilized to develop the plane lateral to the psoas and to reflect the peritoneal sac anteriorly. Retroperitoneal fat was gently dissected. The psoas muscle was palpated.
SEQUENTIAL TUBE DILATION: Sequential tube dilation was performed with the NuVasive NeuroVision system with triggered EMG hunting algorithms and fluoroscopic guidance gently spreading the fibers of the psoas muscle and docking on the left L3-4 disc annulus. A K wire was inserted into the left L3-4 disc annulus for stabilization. The Maxcess retractor also under triggered EMG and docked on the disc. This was also performed under fluoroscopic guidance. The lateral annulus was visualized. A hand-held EMG probe was utilized to confirm that no neurologic structures were within the surgical field. Microscopic magnification and microsurgical techniques were also utilized for hemostasis and to confirm that no neurologic structures were at risk.
EXPLORATION OF LEFT LUMBAR PLEXUS: The left L3 nerve root was visualized and explored status-post discitis with extradiscal and foraminal extension resulting in radiculopathy. Neuroloysis of the left L3 nerve root and lumbar plexus was performed utilizing surgical microscopy and microsurgical techniques. At the the completion of the this portion of the procedure, the L3 nerve root and component of the lumbar plexus was free of further compression.
ANTERIOR DISCECTOMY: An annulotomy was performed in the left lateral annulus followed by discectomy with pituitary rongeurs and Kerrison rongeurs. A sharp Cobb was utilized to elevate the cartilaginous endplates were well was left to them off of the cephalad aspect of L4 and the caudad aspect of L3. The remaining cartilaginous endplates were removed. There was no gross evidence of infection in this disc. Similarly, the bone was of good quality. Ring curettes and rasps were utilized to prepare the endplates with healthy bleeding bone.BONE MARROW HARVEST: 10cc of bone marrow was harvested from S1 utilizing a Jamshidi needle and syringe for autologous fusion purposes.
ILIAC CREST BONE MARROW HARVEST: A Jamshidi needle was inserted through a separate fascial incision and separate skin incision into the left posterior superior iliac spine. 5 cc of bone marrow was aspirated in order to combine with of ethos tricalcium phosphate allograft for fusion purposes.
ANTERIOR LUMBAR INTERBODY FUSION: An appropriate-sized NuVasive titanium cage was chosen with a 55 mm x 22 mm lordotic footprint 8mm cage chosen. This was filled with a combination of local autogenous bone graft saved from the endplate shavings, allograft with bone marrow aspirate and extra small infuse. The cage was then inserted under fluoroscopic guidance. Excellent distraction and fit was noted.
