rotation. discosteophyte complex and loss of disc height, chondrosseous spurs of facet and uncovertebral joints, between posterior edge of uncinate and lateral edge of PLL, usually presents with myelopathic symptoms, combined cervical root compression and distal nerve compression, decreased axoplasmic flow from root compression predisposes downstream nerves to peripheral entrapment syndromes, C6/7 disease will affect the C7 nerve root, facet hypertrophy and osteophytes can impinge on nerve root posteriorly, loss of disc height can decrease volume of neuroforamen, osteophytes from posterior joint can impinge on exiting nerve anteriorly, thick fibrous outer layer of the intervertebral disc, "cushioning" between the vertebral bodies, contains type II collagen and glycosaminoglycans (GAGs), GAGs contains a high negative charge and attacts large amounts of water molecules, 90% water content in patients under 30 years of age, decreases to 70% by eighth decade of life, key differences between cervical and lumbar spine are, cervical spine C6 nerve root travels above C6 pedicle (mismatch), lumbar spine L5 nerve root travels under L5 pedicle (match), extra C8 nerve root (no C8 pedicle) allows transition, horizontal (cervical) vs. vertical (lumbar) anatomy of nerve root, because of vertical anatomy of lumbar nerve root, a paracentral and foraminal disc will affect different

flexion of middle and index finger (difficulty with fine motor function), C8 radiculopathy is extremely rare and often manifests similarly as ulnar neuropathy, simultaneous extension, rotation to affected side, lateral bend, and vertical compression reproduces symptoms in ipsilateral arm, narrowing of the intervertebral foramina causes exacerbation of symptoms, specific, but not sensitive for radiculopathy, shoulder abduction (lifting arm above head) often relieves symptoms, valuable physical exam test to differentiate cervical pathology from other causes of shoulder/arm pain, check for findings of myelopathy in large central disc herniations, AP, lateral, oblique views of cervical spine, obtain flexion and extension views if suspicion for instability, degenerative changes of uncovertebral and facet joints, disc space narrowing & endplate sclerosis, important to look for sagittal alignment and spinal canal diameter, best view to identify foraminal stenosis caused by

adjacent level disease remains unclear, some studies show 3% per year for all approaches, systematic reviews have demonstrated no difference in ASD rate between CDA and ACDF, lower neck pain intensity and frequency with CDA, high incidence of heterotopic bone formation, techniques (very few substantiated by evidence), immobilization for short period of time (< 1-2 weeks) may help by decreasing inflammation and muscles spasm, prolonged immobilization should be avoided, injection consisting of steroid and local anesthetic, studies have shown no difference in long-term pain relief with local anesthetic alone and combined steroid, transverse incision for 1- and 2-level disease, longitudinal incision for multilevel disease and corpectomies or patients with short and thick necks, increased risk of thoracic duct injury with left-sided approach, lower risk of recurrent laryngeal nerve injury with left-sided approach, recurrent laryngeal nerve passes between trachea and esophagus, retractor displacement compresses nerve against inflated endotracheal tube, cuff deflation can theoretically decrease recurrent laryngeal nerve injury, placement of bone graft increases disk height and decompresses the neural foramen through indirect decompression, corpectomy and strut graft may be required for multilevel spondylosis, anterior plating functions to increase fusion rates and preserve position of interbody cage or strut graft, increased cost and complication risk for increased exposure, decreases implant extrusion and graft collapse, historically, plating required bicortical fixation (Caspar plates), intraoperative fluoroscopy used to prevent over penetration of screws, modern plating contains constraining mechanism to allow sufficient fixation with unicortical screws, allow controlled settling of the interbody construct and physiologic loading of the graft, theoretical benefit of increased fusion rates and decreased screw pull out, maintains screws at fixed angles through plate (similar to locking plate), no difference in fusion rates with single-level disease with plating compared to no plating, increased fusion rate, decreased graft complications, lower reoperation rate, and earlier return to work with plating in multilevel disease, careful dissection of the inner and outer tables of the ilium, higher potential for disease transmission, higher

stripping from lamina and spinous process, lateral exposure to the lateral border of the lateral mass, no difference in effectiveness of decompression compared to open foraminotomy, if anterior disc herniation is to be removed, then superior portion of inferior pedicle should be removed, nerve root decompressed posteriorly, superiorly, and inferiorly, avoids problems associated with anterior procedure, more difficult to remove discosteophyte complex, significant muscle pain and spasm (muscle splitting approach), 5 to 10% for single level fusions, 30% for multilevel fusions, improved fusion rates seen with posterior fusion, most common nerve injury from this operation, anatomic course of the nerve differs on the right and left side.
