who presents with post-traumatic spinal deformity and hardware failure.Imaging reveals l1 burst fracture, treated with t12-l2 fusion with fracture of bilateral l2 screws and rod pull out.She has a focal kyposis, on supine imaging, from t12- l2 of 38 degrees.There is no fusion across the surgical segment.Treatment options were discussed including observation, conservative and surgical.After review of neurological exam, clinical history, and radiological studies, surgery is offered to the patient to entail, removal of instrumentation, t10 to l3 fixation and fusion, l1 pedicle subtraction (3 column) osteotomy, and bilateral paraspinal thoracic muscle flaps.The indications, methods, alternatives, and risks of spinal fusion surgery were described in detail to the patient.Indications include decompression of the thecal sac and nerve roots to alleviate the patient's symptoms, as well as stabilizing degenerated motion segments.Methods include an open surgical approach utilizing fixation hardware.Alternatives include continued conservative therapy with injections, physical therapy, and analgesic medications versus an anterior approach.Risks of surgery include, but are not limited to death, coma, paralysis, infection, need for additional surgery, spinal fluid leak, delayed spinal instability, nerve root injury, etc.Additional risks include hardware failure, graft failure, pseudoarthrosis, adjacent level disease, and the need for additional surgery.Medical complications including deep venous thrombosis and pulmonary embolism, pneumonia, urinary tract infection, cerebrovascular accident, blindness, and myocardial infarction, etc., were also reviewed.Operative findings: baseline emgs remained stable.All lumbar screws stimulated to at least 20ma without emg response.Fluoroscopy at the end of the case showed proper hardware placement with excellent reduction in kyphosis.Due to the patient's previous decompression, fixation, fusion and severe focal kyphosis, this case constituted a complex procedure.Each and every aspect of the case, from positioning through exposure, decompression, instrumentation and closure required an additional 50% effort.Given the degree of correction we obtained with positioning, was smaller than expected, we felt a pedicle subtraction osteotomy would not provide enough correction to bring her thoracolumbar junction into neutral alignment.Therefore an intraoperative decision was made to perform a complete vertebral column resection, schwab grade 5 osteotomy, at l1 and fuse the segments with a small interbody cage from t12-l2 and anterior arthrodesis.In addition, given the complete vertebral column resection we decided to make our distal instrumented level l4 rather than l3 to provide a stronger structural base of the construct.Description of procedure: following the induction of general anesthesia, baseline ssep,meps and emgs were obtained.These remained constant throughout the entire case.The patient was carefully positioned on the operative table in the prone position with their chest and abdomen supported on the jackson table.A midline thoracolumbar incision over the planned site was plotted with a surgical marker over her previous incision.The posterior region was prepped and draped in the usual sterile fashion.Following universal timeout, an incision was made from the top of t10 to the bottom of l4 excellent hemostasis was maintained throughout the entire case, utilizing the bipolar, aquamantus and bovie electrocautery devices.A subperiosteal dissection was undertaken along the lamina and retractors were placed.The transverse processes were exposed bilaterally at these levels and decorticated.The prior segmental fixation was directly beneath the skin and had eroded through the muscle layer.It was a t12 through l2 non segmental fixation with a cross-link from the medtronic solera system.We removed the locking caps from the screws and remove the set caps and rods as well as the cross link, we inspected the posterior fusion and it was well fused at t12 and l1, but not down to l2.The l2 pedicle screws had fractured in the middle of the screw shanks, as read seen on preoperative imaging.In order to remove the retained shanks, we drilled around the entry site for the fractured l2 pedicle screws, and using a clamp, were able to helicopter the retained screws out of the body.Given that bone had already overgrown these retained screw shanks, this maneuver to remove them required significant time and effort.We upsized screws at the same holes using 6.5 mm globus creo pedicle screws at l2.A clamp was affixed to the spinous process of t9 and to this, we attached the o-arm star array.The field was then flooded with irri gation and covered with sterile drapes.The o-arm was brought into the field and an intraoperative ct scan was performed of the spine.The scan was uploaded to a separate stealth station for use with neuro-navigation.Using navigation assistance, the pedicles bilaterally at t10, t11, t12, l3 and l4 were cannulated and tapped.7.5 mm and 6.5 mm globus creo screws were then placed into these pedicles.Attention was then turned to the decompression.A significant amount of time was spent elevating the epidural scar over the l1 lamina.We were able to obtain a reasonable epidural plane resected all of the epidural scar.We then extended the laminectomy is widely at l1, and performed laminectomies at t12 and l2 to widely decompress the central canal.The pars and l1-2 facet joints were also removed.The bone was saved for eventual arthrodesis autograft.Given the need to correct the kyphosis significantly, we performed a posterior column osteotomy at t12 by resecting the complete facet joints at t12-l1 as well as the pars interarticularis at t12 to release the level.We skeletonized the t12 nerve roots with this maneuver.Intraoperative x-ray was checked and we felt that close to 45° of kyphotic correction was needed at her focal l1 kyphosis and this would not be able to be obtained with a standard 3 column osteotomy.I needed to perform a vertebral column resection and kyphectomy and interbody arthrodesis at l1 in order to obtain this corr ection and changed the operative plan.The l1 pedicles were skeletonized and ligament was removed as were the transverse processes.We then followed the l1 nerve roots out laterally to completely decompress them past the lateral border of the l2 pedicles.Bilateral pediculectomies were performed at l1 to bring the dissection down to the ventral canal level.Temporary rods were then placed across the l1 level to stabilize the spine during the vertebral column resection.In order to perform the kyphectomy, we dissected in a subperiosteal fashion around the lateral borders of the l1 vertebral body with care not to violate the segmental vessels, which had to be coagulated on the right side.Cottonoids were placed in the lateral gutters to keep this lateral exposure of the vertebral body.We then used a combination of osteotomes and the drill perform a complete l1 corpectomy.Bone was saved for eventual arthrodesis.We skeletonized the lateral cortical borders as well as a ventral cortical border of the l1 vertebral body.We then performed discectomies at t12-l1 and l1-l2 to prepare these endplates for arthrodesis by this lateral extra cavitary approach at l1.Once the disks were removed on either end of the dissection and the entire vertebral body was removed, rongeurs were used to remove the lateral cortical borders of l1.We then advanced the cottonoids from a lateral to medial fashion under the ventral border of the spinal column to obtain circumferential dissection.The anterior cortical wall of the l1 vertebral body was then removed with a kerrison to constitute the schwab grade 5 osteotomy or kyphectomy at l1.Overall, this maneuver was quite challenging given the degree of kyphosis and the degree of correction needed and required significantly more additional time and effort than in a standard case.Zimmer trellos tlif banana interbody cage trials were used to side the graft.After the preparation of the endplates was performed, a 16 mm height, 0° lordotic, 32 mm length zimmer trellos titanium cage was selected and packed with a combination of infuse bmp as well as autograft.It was inserted through a right lateral extra cavitary approach into the interspace between the t12 and l2 vertebral bodies and centered against the anterior longitudinal ligament.This constituted the arthrodesis with lateral extra cavitary technique from t12-l2.Once in position, the temporary rods were gently released and compression was applied to sear the interbody in place.By levering the posterior column of the spine across his interbody, we were able to significantly improve the kyphosis at the vertebral column resection site, and l1 obtained nearly parallel endplates at t12 and l2.Globus creo tulip heads were removed at select screws and creo amp double tulip heads were placed to allow for better satellite rod fixation.A temporary rod was provisionally tightened, while the other one was removed.Using the new invasive bandini system, a 5.5 mm titanium rod was cut and contoured and placed into the pedicle screws from t 10 through l4.We then provisionally tighten this and perform the same bending and cutting of the other sidedrod.The rods were then placed over the inner tulip heads and carefully reduced with reduction towers to improve the patient's overall sagittal and coronal alignment.Set caps were provisionally tightened.This added to the neutral alignment restoration.All set caps were locked, tightened and torque tightened to constitute the segmental fixation from t10-l4.In performing this fixation, we were able to treat her nonhealing l1 fracture and open manner, orif lumbar fracture.Additional satellite 5.5 mm titanium rods were then applied to the offset connectors from the amp heads bilaterally, and were placed across the l1 vertebrectomy level.Set caps were placed and final tightened on both sides to yield a four-rod construct.The placement of the satellite rods took additional time and effort, but we felt it was necessary given the severe instability of the spine after the kyphectomy.Final radiography showed excellent restoration of alignment without any hardware complications.The wound was copiously irrigated with 1 l of antibiotic solution and a pulse irrigation system.Transverse processes at all the vertebral levels had been decorticated earlier in the surgery, a small amount of duraseal was placed over the exposed dura, although there was no spinal fluid leak.A mixture of infuse bmp, stryker dbm and xemplifi dbm and the patient's own bone were packed into the interstices at all levels to constitute the allograft and autograft posterolateral fusions from t10-l4.Given the patient's previous scarring from prior surgeries, as well as the length of the incision and dissection, an intraoperative decision was made to perform a bilateral thoracolumbar muscle advancement flap closure.The purpose of the flap closure was to close the fascia in watertight fashion and allow a tension-less skin closure, as well as to allow appropriate soft tissue coverage of the spinal instrumentation.The flap will be fed by branches of the lumbar and thoracic segmental arteries which were protected throughout the dissection and closure.We isolated the right thoracolumbar araspinal muscle and used bovie cautery to dissect above this in the subfascial plane.This was done laterally with avoidance of coagulating the skin perforators in the soft tissue.Once adequate lateral dissection was completed, we performed the same flap isolation on the left side.The deep aspect of the flaps had already been elevated off the transverse processes during the earlier part of the spinal dissection.Back cuts in the muscle were made as nee ded to allow for mobilization medially.Vancomycin powder was placed in the deep cavity and two 19 fr blake drain was tunneled out from the deep compartment on the hardware.The muscle flaps were advanced from lateral to medial and the closed with interrupted imbricating horizontal mattress suture using 0 vicryl.Two additional 19 fr blake drain were placed in the subfascial space and the fascia was closed with 0-vicryl.The deep subcutaneous tissues were closed with 0 and 2-0 vicryl.The skin was closed with 4-0 monocryl and prenio dermabond after the installation of marcaine.There were no intraoperative complications.The sponge and needle counts were reported to be correct x2, as verified by the operating room staff.Estimated blood loss:

12/03/2020 reviewed in epic.Mri t and l-spine w/o contrast 11/27/20: 1.Overall stable postsurgical changes of posterior spinal fusion from t12 to l2 with ll laminectomy.The fractured l2 pedicle screws are better visualized on prior lumbar spine ct.2.Associated moderate to severe chronic l1 vertebral burst fracture with minimal fracture retropulsion is unchanged.3.Patent thoracic spinal canal and foramina.Plan: - checking bmp, cbc, coags now - maintain normotension - jp drains x4 to bulb suction incisional pico intact - advance diet as tolerated - pain control with pca and prn medications - mobilize as tolerated plan: - checking bmp, cbc, coags now - maintain normotension - jp drains x4 to bulb suction incisional pico intact - advance diet as tolerated - pain control with pca and prn medications - mobilize as tolerated imaging reviewed in epic.12/03/2020 imaging results: recording parameters: pf1, pf2, cv, cp3, cp4, cpz, and fpz.Free-running and triggered emg of left and right iliopsoas (l1-l3), vastus lateralis (l2-4), tibialis anterior (l4-5), lateral gastrocnemius (l5-s2) and abductor hallucis (s1-s2) muscle groups transcranial electrical motor evoked potentials recorded from the abductor pollicis brevis referenced to the abductor digiti quinti minim' muscle groups, the tibialis anterior referenced to the gastrocnemius muscle groups, and the abductor hallucis muscle groups.Free-running eeg recorded with bipolar derivation, using modified international 10/20 placements: c3-fpz, c4-fpz.Description: intraoperative neurophysiological monitoring was performed using a combination of upper and lower extremity somatosensory evoked potentials, transcranial electrical motor evoked potentials, free-running and triggered emg of l1-s2 innervated muscle groups and free-running eegs.A real-time connection with the examining neurologist was established and maintained throughout the operative procedure by the monitoring technologist.Upper extremity somatosensory evoked potentials were recorded centrally at the cervical and cortical levels following ulnar nerve stimulation at the wrists.Lower extremity somatosensory evoked potentials were recorded centrally at the cervical and cortical levels following posterior tibial nerve stimulation at the ankles.Tcemeps were recorded peripherally from the upper and lower extremities following alternating polarity motor strip stimulation.Post-prone positioning tcemep recording responses to motor cortex stimulation were clear and reproducible bilaterally.No significant surgically related changes in amplitude or latency of the somatosensory evoked responses or tcemeps were noted throughout the surgical procedure.At closing, responses were judged to be essentially unchanged from those of post-positioning baselines.Free-running emg of l1-s2 innervated muscle group was monitored continuously throughout the operative procedure with no sustained neurotonic discharges seen.Triggered emg was performed following the placement of each pedicle screw via a sterile ball-tip probe held by the surgeon.The resulting intensity values required to elicit a response from each placement were reported to the surgeon.The resulting intensity values required to elicit a response from each placement were 10 ma or above.Free-running eeg remained symmetrical throughout the procedure with no focal changes noted to occur.Conclusion: these results suggest the absence of untoward, secondary effects on the anterior and posterior column function as a consequence of this surgical procedure.In addition, absence of sustained neurotonic discharges on free-running emg suggests that the nerve roots monitored remained undisturbed.All values elicited by triggered emg during pedicle screw placement were reported to the surgeon.Performed: 12/03/20 final report x-ray lumbar spine one view history: the film taken in the or.Findings: transpedicular screws extending from the lower thoracic and 4 vertebrae, harrington type rods, an intervertebral metallic cage at l1-l2, surgical markers are noted.X-ray chest ap history: confirm central line placement comparison: 3 days prior findings: a right ij route large bore central venous catheter is seen with the tip at the caring.Another catheter which could be coaxial extends further distally with the tip overlying right atrium.Multiple leads and tubes overlying the chest obscured the details.There is no pneumothorax.There is trace bilateral pleural effusions.Multiple surgical staples overlying the lower chest and upper abdomen are new.The spinal orthopedic hardware is changed in the interim.Impression: right ij central venous catheter as above apparently in satisfactory position.No pneumothorax.Clinical indication: shortness of breath comparison: 12/3/2020 the patient is rotated to the left.The cardio mediastinal contours are stable.The lung volumes remain low.Central vascular engorgement and bilateral interstitial and patchy airspace opacity centered on the perihilar lungs have slightly worsened, suggesting worsening pulmonary edema.Pneumonitis should be excluded clinically.There is no pneumothorax.Support lines are stable.Clinical indication: constipation comparison: none technique: single, frontal radiograph of the abdomen.Findings: the bowel gas pattern demonstrates diffuse gaseous distention of small bowel loops.Colon is stool-filled.The regional skeleton is intact.Technique: two views of the lumbar spine.Indication: s/p t10 -
