E Preoperative Plan 1 Identifies area of decompression on preoperative imaging 2 Execute surgical walkthrough describe steps to the attending prior to the start of the case describe potential complications and list steps to avoid them F Room Preparation 1 Surgical instrumentation laminectomy set 2 Room setup and equipment table standard radiolucent table with Wilson frame vs. Jackson spine flat top table C-arm c-arm perpendicular to table microscope (optional) microscope in from opposite side of C-arm 3 Patient positioning prone with arms at 90° max abduction and flexion to prevent axillary nerve injury foam padding on chest so that nipples are pointing midline straight down pads over ASIS and gel pads on knees bilateral TED hose and SCDs G Superficial Dissection to Expose Spinous Process 1 Localize level of incision with anatomic or radiographic landmarks 2 Make midline incision. midline incision with 10blade overlying the spinous processes between paraspinal muscles (erector spinae) ~3-4cm in length for single level 3 Dissect subcutaneous tissue down to fascia insert cerebellar retractors x2 for fascial exposure 4 Cauterize lumbodorsal fascia over spinous processes to just lateral of midline H Deep Dissection down to Lamina 1 Subperiosteal dissection with Cobb along spinous processes 2 Subperiosteal dissection of lamina cranial to caudal down to lamina 3 Place probe under lamina to identify level radiographically 4 Use Cobb to strip laterally along lamina until facet capsules identified but not violated 5 Place deep retractors for better visualization I Laminectomy and Central Decompression 1 Remove spinous processes of operative levels with rongeur save as bone graft for fusion 2 Remove lamina and identify origin of ligamentum flavum begin with decompression into canal into inferior half of lamina of cephalad vertebrae first with small curette burr lamina and to thin and then complete resection with Kerrison rongeurs 3 Resect ligamentum flavum gently retract ligamentum flavum with woodsen elevator resect remaining lamina and ligamentum with Kerrison rongeur of cephalad vertebrae resect ligamentum from superior lamina of inferior lamina use Kerrison to resect caudad lamina from inferior vertebra J Lateral Recess and Foraminal Decompression 1 Perform Medial facetectomy decompress medial aspect of facet on each side (2-3 mm of medial facet) 2 Decompress lateral recess locating pedicle key to safe decompression kerrison to undercut medial edge of superior facet of caudad vertebra until medial edge of pedicle visualized identify osteophytes that could impinge exiting nerve root around pedicle undercut remaining superior facet using kerrison rongeur no more than 50% superior facet should be resected 3 Confirm exiting and descending nerve roots are well decompressed descending nerve root should be visualized 4 Check to make sure no disc herniation. Dural sac/nerve root may be retracted to see if there is bulging disc is present K Wound Closure 1 Irrigation, hemostasis, and drain flush out spine with saline bulb irrigation 2 Deep closure close fascia with 0-vicryl need water tight closure and need to decrease dead space for hematoma 3 Superficial closure subcutaneous with 2-0 vicryl skin closure with buried 3-0 monocryl 4 Dressing soft incision dressings over spine
