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 assistant and helped facilitate the case.Procedure: after adequate general anesthesia was obtained the patient was placed prone on a jackson table, the back was prepped and draped in the usual stented 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, lateral recess and foraminal stenosis.This was completely decompressed.Using curved and straight curettes as well as kerrison¿s, removal of

all nerve roots were 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 pedicle screws.The pedicle screw starting hole position was identified followed by placement of pedicle finder.Once pedicle verified, the top was then used with placement of a ball probe with verification and visualization of pedicles to ensure there is no breach of the pedicle or nerve root contact once this was performed, the screws was then measure and placed.6.5 x 40 screws were used at l3-l5.7 5x 35 mm screws were used in s1 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: plain films are performed today and reviewed to evaluate the fusion demonstrate decompression and fusion with instrumentation doing well.Impression: spinal stenosis, scoliosis s/p decompression, and fusion doing well.(b)(6) 2021: the patient returns for reevaluation.She is s/p decompression and fusion with instrumentation l3-s1.Unfortunately, she had broken screws un the sacrum.She has pain in the area where the heads of the screws are likely rubbing.Radiographs: plain films are performed today and reviewed to evaluate the fusion demonstrate broken pedicle screw in the sacrum.Impression: s/p decompression and fusion l3-s1 for spondylolisthesis with spinal stenosis and broken hardware.(b)(6) 2021: indications: patient presented to the office with chief complaint of severe pain in the back with radiation to the buttock and leg.The patient reports the pain is severe and incapacitating to the point that the patient is unable to function.All therapeutic

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.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 pituitaries 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
