MRI is essential in all cases of Segond fractures to identify internal derangement. In a patient with arm pain and paresthesias, which of the following symptoms or physical exam findings supports a cervical radiculopathy as opposed to a peripheral neuropathy. indications. (SBQ11AN.18) He reports the pain began following a tennis match and has not improved with time. 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 nerve roots, because of horizontal anatomy of cervical nerve root, a central and foraminal disc will affect the same nerve root, may present with insidious onset of neck pain that is worse with vertebral motion, origin may be discogenic, or mechanical due to facet arthrosis, unilateral dermatomal numbness & tingling, numbness and pain at the base of the neck, pain and numbness in the superior shoulder and lateral upper arm, brachioradialis and wrist extension weakness, most commonly affected nerve root in cervical radiculopathy in several studies, weakness to distal phalanx 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 osteophytes, important to look for angular or translational instability, look for compensatory subluxation above or below the spondylotic/stiff segment, changes often do not correlate with symptoms, 70% of patients by 70 yrs of age will have degenerative changes seen on plain xrays, persisent symptoms despite 6 weeks of conservative treatment, T2 axial imaging is the modality of choice and gives needed information on the status of the soft tissues, loss of CSF signal around the cord and nerve root, foraminal stenosis with nerve root compression (loss of perineural fat), has high rate of false positive (28% greater than age of 40 will have findings of HNP or foraminal stenosis), >50% over the age of 40 years will have a degenerated disc, gives useful information on bony anatomy including osteophyte formation that is compressing the neural elements, useful as a preoperative planning tool to plan instrumentation, detect ossification of the posterior longitudinal ligament, may not be as evident on MRI or radiography, study of choice to evaluate for postoperative pseudoarthosis, useful in patients who cannot have an MRI due to pacemaker, etc, useful in patients with prior surgery and hardware causing artifact on MRI, intrathecal injection of water soluble contrast given via C1-C2 puncture and allowed to diffuse caudally, lumbar puncture and allowed to diffuse proximally by putting patient in Trendelenburg position, controversial and rarely indicated in cervical spondylosis, approach is similar to that used with ACDF, risks include esophageal puncture and disc infection, may be useful to distinguish peripheral from central process (ALS), fibrillations and positive sharp waves in the affected distribution, may not manifest until 3 weeks after onset of symptoms, paraspinal muscles are affected before appendicular muscles, sensory nerve action potentials are typically normal, compression is usually proximal to the dorsal root ganglion, compound muscle action potential proportional decrease to muscle atrophy, Selective nerve root corticosteroid injections, may help confirm level of radiculopathy in patients with multiple level disease, and when physical exam findings and EMG fail to localize level, 75% of patients with radiculopathy improve with nonoperative management, improvement via resorption of soft discs and decreased inflammation around irritated nerve roots, indicated after resolution of symptoms and repeat MRI demonstrating no cord compression, studies have shown return to play expedited with brief course of oral methylprednisolone (medrol dose pack), no increased risk of subsequent spinal cord injury, selective nerve root corticosteroid injections, may be considered as therapeutic or diagnostic option, provides long-term relief in 40-70% of cases, increased risk when compared to lumbar selective nerve root injections with the following rare but possible complications, including, persistent and disabling pain that has failed, progressive and significant neurologic deficits, static neurologic deficit associated with significant radicular pain, remains gold standard in surgical treatment of cervical radiculopathy, single level ACDF is not a contraindication for return to play for athletes, very high success rate with single level disease, higher rate of pseudoarthrosis with multilevel procedures, 20% for single level ACDF vs >50% for multilevel ACDF, pseudoarthrosis rate does not appear to correlate with clinical outcomes, isolated unilateral nerve root compresssion, 98% excellent outcomes reported in literature, may be used in osteophytic foraminal narrowing, high risk patients with anterior approach, reduces the risk of iatrogenic injury with anterior approaches, no difference in outcomes compared to ACDF, faster return to work and lower treatment cost than ACDF, single level disease with minimal arthrosis of the facets, no difference in arm pain, NDI, SF-36 scores, and neurologic improvement, effect on 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 pseudoarthrosis rates (41% vs 27%), higher graft subsidence rates (28% vs 16%), soft collar immobilization for short period of time, prolonged immobilization in hard collar if anterior plating not used, range of motion and strengthening beginning at 6 weeks, complications of anterior surgery including persistent swallowing problems, anterolateral approach to the cervical spine, medial to the anterior tubercle of the transverse process, potential risk of sympathetic chain and vertebral artery injury, limits epidural bleeding (less engorgement of veins compared to prone positioning), muscle 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.
