including physical therapy, anti-inflammatories, pain clinic and epidural blocks and the patient elected to proceed.The risks of surgery, which include but are not limited to infection, failure of operation, need for future operations, possibility of injury to arteries, nerves, and veins, possibility of permanent numbness, tingling, weakness, loss of bowel and bladder function, the risk to adjacent levels, need for future surgery, possibility of pedicle screw fracture or displacement or loosening, possibility of failure of fusion, the fact that smoking adversely affects the fusion, the prolonged period of recovery including up to one year to eighteen months for bone healing and up to two years for nerve healing.The patient understands the risk of surgery, they understand there are no promises or guarantees and they elected to proceed informed consent is obtained.The pa was present for the entire procedure and participated is all aspects of the care.He functioned as a first

fashion all bony prominences are adequately padded so there is no evidence of any areas where there is any pressure on the skin or bony prominences or nerves.A pause was then used for keystone and surgical consent verification.Once this was completed surgical prep was performed and the back prepped and draped in the usual sterile fashion.A single incision was made over the back dissection was carried to the level of the spinous process.Kocher was placed.Lateral x-ray was obtained for verification of the level.During this time, the paraspinous muscles were reflected off the tips of the spinous process and past the facet joints to the transverse processes.The facet joints and transverse processes are exposed, and isolated central decompressive laminectomy was then performed at l3-s1 using leksell rongeur and kerrison.The lateral recesses were completely decompressed.Neurolysis was performed using 4.0 curved and straight curettes.The patient was found to have severe central canal,

bilaterally.Following this, a rod was then placed into the wound, distraction was carried out when necessary.Bone marrow aspiration was then performed using the trocar and the iliac crest 60 cc of bone marrow was then mixed with allo-autograft and placed over decorticated transverse processes.The construct was tightened into position and an x-ray was obtained for verification and position of the hardware.The neural foramina were once again palpated for a final time to ensure there was no evidence of any residual nerve compression.The fascia was then reapproximated with #1 vicryl over a medium hemovac drain, subcutaneous tissue was closed with 2-0, the skin was closed with 4-0 and steri-strips were applied.The patient tolerated the procedure well and was taken to the recovery room in satisfactory condition.There were no complications.Specimen(s) removed: scar, arthritis, disc, spur.Operation: decompressive lumbar laminectomy l3-s1 with foraminotomies with discectomy with posterolateral fusion l3-51 with bone marrow aspiration with allo/autograft posterolateral fusion l3-s1 with segmental pedicle screw fixation l3-s1.(b)(6) 2020: the patient returns to office and she had s/p decompressive lumbar laminectomy and fusion with instrumentation.She reports she is feeling significantly better.She went to florida for six weeks and reports it has been great.Radiographs:

and past the facet joints to the transverse processes.The facet joints and transverse processes are exposed and isolated.The previous hardware was identified and removed, and the fusion was explored.The sacral screws were broken bilaterally, and the broken screw removal set was used and the screws were removed.Revision decompressive laminectomy was then performed at l2-s1 using leksell rongeur and kerrison.The lateral recesses were completely decompressed.Neurolysis was performed using 4.0 curved and straight curettes.The patient was found to have severe central canal, lateral recess and foraminal stenosis.This was completely decompressed.Using curved and straight curettes as well as kerrison¿s, removal of ligamentum flavum, hypertrophic facet joints, and foraminotomies was then performed.Discectomy was then performed using a 15-scalpel blade and pitutaries at l5-s1.Angled dural separators were then passed x3 sequentially into each neuro-foramina to make sure that all nerve roots wore free.Once it had been ascertained that there was no evidence of any residual central canal, lateral recess or foraminal stenosis attention was then turned to placement of the bmp.Bone marrow aspiration was then performed using the trocar and the iliac crest 60 cc of bone marrow was then mixed with allo-autograft and placed over decorticated transverse processes.The neural foramina were once again palpated for a final time to ensure there was no evidence of any residual nerve compression.The fascia was then reapproximated with #1 vicryl over a medium hemovac drain, subcutaneous

movements especially into the right leg.Recent mri discussed with patient.She will follow up with ortho spine.Scan results: 29-jul-2021: lumbosacral view ¿ comparison: ct of lumbar spine from 25/jun/2021.Impression: 1.Lateral intraoperative film demonstrates laminectomy changes in the lower lumbar spine and interval removal of the previously seen fusion hardware from l3 through s1.Minimal anterolisthesis of l4 on l5.Refer to the operative report for further real-time findings.02-sept-2022: mri lumbosacral spine with and without contrast.9/5/2022 there graft history: low back pain, right sided, sciatica multiplanar, multi sequential magnetic resonance imaging of the lumbosacral spine was obtained both before and after the uneventful administration of 10 cc mv contrast.There are no similar examinations for comparison at this institution.Postoperative findings seen within the mid and lower lumbar spine, with posterior decompression at each of these levels.There is straightening of the posterior soft tissues and there appears to be a small contained simple appearing fluid collection measuring 1.4 x 22 x 5.2 cm in ap, transverse and cranial caudal dimensions.There is no evidence of unexpected, abnormal enhancement.These findings are probably related to seroma.The conus terminates at l1, demonstrates normal signal morphology and the nerve roots are grossly unremarkable.There is no evidence of abnormal enhancement of the conus or the nerve roots.There is some anterolisthesis of l3 upon l4 and l4 upon l5 and there is slight levo scoliosis of the lower lumbar spine.There is no compression fracture seen.There is no traumatic malalignment.Some heterogeneity of the marrow spaces consistent with fatty marrow conversion.There is no infiltrative signal abnormality to suggest a marrow placing process.No pathologic edema on the fluid sensitive sequence.There is scattered disc space height loss at multiple levels without evidence of abnormal enhancement.At t11-t12, t12-l1, l1-l2, normal.No significant spinal canal stenosis or neural foraminal narrowing.At l2-l3, mild facet changes without significant spinal canal stenosis or neural foraminal narrowing.At l3-l4.Unroofing of the disc with posterior decompression.The thecal sac is patent and the neural foramina are slightly narrowed on the left and patent on the right.At l4-l5, unroofing of the disc and there has been posterior decompression with a patent thecal sac overall.Facet changes are seen bilaterally and there is minimal right-sided neural foraminal narrowing.Left neural foramen is patent.At l5-s1, facet changes bilaterally and posterior decompression.A disc spur herniation without significant spinal canal stenosis and there is minimal left-sided neural foraminal narrowing.Right neural foramen is patent.Limited assessment of the retroperitoneal soft tissues and appears final soft tissues are within normal limits.
