C2 to C4 posterior cervical segmental arthrodesis.2. Posterior cervical instrumentation with C2 pars screws, as well as C3 and C4 lateral mass screws, using the StrykerOASYS system.3. Use of BIO4 allograft.4. Harvest of local bone autograft from spinous processes.5. Bone marrow aspiration from right superior posterior iliac crest via separate stab incision.6. Use and interpretation of neurophysiologic monitoring.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARY16

6/17/2021CERVICAL FUSION CASE (CONTINUED)INDICATIONS: This 59-year-old female has been experiencing worsening neck pain and was diagnosed with C2-3anterolisthesis with evidence of dynamic instability Posterior cervical instrumented fusion was recommended to stabilizeher cervical spine. The risks, benefits, and alternatives to surgery were reviewed at length with the patient and spouse.Risks include but are not limited to bleeding, infection, need for future procedures including extension of fusion;pseudoarthrosis, failure of implants, permanent neurologic deficit such as numbness, weakness; wound problems,medical complications, and even stroke, coma, paralysis, and death. The patient acknowledged these risks, allquestions were answered, and she asked to proceed.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARYCERVICAL FUSION CASE (CONTINUED)DESCRIPTION OF PROCEDURE: The patient was brought to the operating room where she was intubated andsedated by the Anesthesia team without incident. Neurophysiologic monitoring was set up, and she was then flipped tothe prone position with her head secured in a 3-point Mayfield device. Post-flip neurophysiologic data remained stable.Intraoperative fluoroscopy was used to mark the appropriate level for the skin incision. The skin was sterilely preppedand draped in standard fashion. A final timeout was performed to verify the correct patient, procedure, and surgical site.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARY17

6/17/2021CERVICAL FUSION CASE (CONTINUED)A 15-blade was used to make a midline posterior cervical incision from approximately C2 to C4. The Bovieelectrocautery continued the soft tissue dissection down to the posterior cervical fascia. The dissection then continued inthe midline avascular plane down to the C2 to C4 spinous processes. A subperiosteal dissection was performed toexpose the C2 through C4 lamina and lateral masses. A Penfield 1 dissector was used to continue the dissection toexpose bilateral C2 pars. Care was taken not to disrupt the C1-2 or C4-5 facet joints.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARYCERVICAL FUSION CASE (CONTINUED)Intraoperative fluoroscopy was used to confirm the appropriate starting point along C2 for the C2 pars screws. A pilothole was made with the high-speed drill. Screw trajectories were drilled under direct fluoroscopic guidance, as well aswith direct visual confirmation of the medial border of the pars. The screw trajectories were tapped and a ball-tip probeconfirmed no breaches. A 3.5 x 18 mm biased-angle screw was placed on the right, while a 3.5 x 16 mm biased-anglescrew was placed on the left.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARY18

6/17/2021CERVICAL FUSION CASE (CONTINUED)Attention was then turned towards the C3 and C4 lateral mass screws. Of note, the patient had particularly small lateralmasses, which thereby necessitated extending the fusion down to C4 in order to ensure a greater purchase.Intraoperative fluoroscopy was again used to confirm appropriate starting points. The high-speed drill was used tocreate pilot holes in bilateral C3 and C4 lateral masses. A hand-twist drill was then used to drill the screw trajectoriesaccording to the Magerl technique. The trajectories were tapped and the ball-tip probe again ensured no breaches.Then, 3.5 x 10 mm biased-angle screws were placed bilaterally at C3 and, on the left at C4, a 3.5 x 14 mm biased-anglescrew was placed on the right at C4 and was left somewhat proud, as this lateral mass was quite deeper whencompared C3.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARYCERVICAL FUSION CASE (CONTINUED)Next, 40 mm titanium alloy rods were placed within the tulip heads, where they were secured with cap screws. AP andlateral x-rays confirmed appropriate positioning of all screws and the cap screws were then final tightened.A stab incision was made over the right posterior superior iliac crest with a 15 blade. A Jamshidi needle was tapped intoplace in order to aspirate approximately 5 mL of bone marrow aspirate. The bone marrow aspirate was combined with 5mL of BIO4 allograft, as well as bone which had been morselized from the C2 through C4 spinous processes. TheJamshidi needle was removed in its entirety and the stab incision was covered with Dermabond.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARY19

6/17/2021CERVICAL FUSION CASE (CONTINUED)The facet joints and lateral masses were decorticated with a high-speed drill. BIO4 allograft was then packed into agreatly expanded left C2-3 facet joint after its cartilaginous surface had been disrupted. The remaining BIO4 andautograft were then packed laterally adjacent to the rod, as well as over the previously decorticated lamina from C2 toC4. The wound was irrigated with copious amounts of antibiotic-containing solution. Exquisite hemostasis wasachieved with the bipolar. The wound was then closed in layers using 0 Vicryl for the muscle and fascia, followed by 2-0Vicryl for the subcutaneous tissue, 3-0 Vicryl for the dermis, and lastly a running 3-0 nylon on the skin. All counts werecorrect x2 at the conclusion of the procedure. No apparent complication was noted. The neurophysiologic monitoringremained stable throughout the entire case.The patient was extubated in the operating room and transported to the recovery area in stable condition.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARYREVIEW THE DOCUMENTATIONWHAT PART OF THE SPINE WAS INVOLVED?

6/17/2021THORACIC FUSION CASE (CONTINUED)DESCRIPTION OF PROCEDURE: Patient was induced under general anesthesia, and an endotracheal tube wasplaced. The patient was then placed in the prone position on Jackson frame. All the pressure points were padded. Iproceeded to localize the levels of T7 to T10 with lateral fluoroscopy, and I marked my incision in the midline.After adequate time-out and after adequate administration of preoperative antibiotics, Decadron as IV, and keeping themean arterial pressure above 90 at all times, I proceeded to make my incision with a 10 blade and achieved adequatesharp dissection through the dermis, subcutaneous tissue, and fascia with monopolar cautery and performedsubperiosteal dissection of the multifidus muscle off the spinous process, lamina, and facets bilaterally at the level of T7,T8, T9, T10, including the transverse processes.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARYTHORACIC FUSION CASE (CONTINUED)At this time, I proceeded to perform a laminectomy at T7, 8, 9, and 10, a 4-level laminectomy, for excision of epiduraltumor, finding tumor along the inferior aspect of T8, full aspect of T9, and partially T10, epidural tumor intimatelyattached to the dura, if not invading the dura on the left side, and mostly on the left side, displacing the spinal cordtowards the right side. Tumor was removed, and I saw the tumor was invading the dura mostly on the left side. Therewas a small amount of spinal fluid leak, which was repaired with fat graft and dural sealant. Adequate hemostasis wasachieved with bipolar coagulation and FloSeal.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARY22

6/17/2021THORACIC FUSION CASE (CONTINUED)After resection of epidural tumor and dural repair, I proceeded to perform an intraoperative CT scan with the O-arm toobtain 3D landmarks for neuronavigation after placing a clamp on the spinous process of T7. We proceeded to placebilateral pedicle screws at the level of T7, bilateral pedicle screws at the level of T8, right-sided pedicle screw at the levelof T9, and bilateral pedicle screws at the level of T10. These were placed under neuronavigation with Stealth spinalneuronavigation, and placement of hardware was confirmed with another O-arm spin, intraoperative CT scan confirmingadequate placement of hardware. After this, one rod was placed on each side, secured to the screw heads with the useof set screws, and the construct was finalized and locked. After the construct was finalized, posterolateral arthrodesisbilaterally with high-speed drill, decortication, and placement of morcellized allograft placed bilaterally at the level of T7T8, T8-T9, and T9-T10, three levels total.YES HIM Consulting, Inc. 2021 CONFIDENTIAL AND PROPRIETARYTHORACIC FUSION CASE (CONTINUED)Two #10 JP flat drains were placed in the epidural space through 2 separate incisions. The drains were secured to theskin with the use of Vicryl stitches, and then after copious irrigation with bacitracin irrigation and adequate hemostasiswith bipolar coagulation and FloSeal, I proceeded to perform closure of the fascia with interrupted sutures of 0 Vicryl,closed this with the interstitial dermis with interrupted sutures of 2-0 Vicryl, and the skin was closed with a running 4-0Rapide reabsorbable suture. The area was dressed in sterile fashion. The patient was allowed to wake up, extubated,and transferred to the postoperative area for further postop care.
