status, family relationship status, physical or mental disability, military status, genetic information or other status protected If MRI shows reduction and no significant compression on spinal cord, then can perform stabilization on urgent (within 24 hours basis), rarely closed reduction followed by immobilization performed, facet dislocations associated with high degree of instability and ligamentous injuries, never perform closed reduction in patient with mental status changes, unilateral dislocations are more difficult to reduce but more stable after reduction, bilateral dislocation are easier to reduce (PLL torn) but less stable following reduction, 26% of patients will fail closed reduction and require open reduction, unilateral facet dislocations effectively closed reduced in 25% of cases, anterior cervical discectomy and fusion (single level), large disc herniation present following reduction with compression on the spinal cord or nerve roots, if closed reduction is failed, may attempt open reduction from anterior approach by distracting across casper pins with simulatenous rotation, 1-level interbody arthrodesis with anterior plating, posterior reduction & instrumented stabilization, bilateral or unilateral facet dislocations that are not reducible from the front or through closed reduction, combined anterior decompression and posterior reduction / stabilization, when disc herniation present that requires decompression in patient that can not be reduced through closed or open anterior technique, emergent MRI then emergent open reduction surgical stabilization, facet dislocations (unilateral or bilateral) in patient with, if disc herniation with presence of spinal cord compression then you must use an anterior approach and do a discectomy, halo is suboptimal in lower cervical spine and therefore hard orthosis may be satifactory without complications associated with a halo, morbidly obese patients may not fit or be adequately stabilized in a halo brace, ability to perform serial neurologic examinations, 1 cm above the pinna and in line with the external auditory meatus, gradually increase axial traction with the addition of weights, can add up to 140 lbs of weight or 70% body weight, average weigh required for reduction ~9.4 to 9.8 lbs per segment above the injury level, a component of cervical flexion can facilitate reduction, flexion moment can be created with pulley system or posterior placement of the Gardner-Wells tongs pins, once reduced, decrease traction weight be 10-15 lbs and apply an extension moment to the cervical spine, perform serial neurologic exams and plain radiographs after addition of each weight addition, abort if there is over distraction of the spinal segment, >1.5 times that if the adjacent uninjured disc space, can switch to carbonfiber Gardner-Wells tongs if need to obtain MRI in traction, abort if neurologic exam worsens and obtain immediate MRI, facet dislocations reduced through closed methods with a MRI showing cervical disc herniation with significant compression on the spinal cord, unilateral facet dislocations that fail closed reduction with a disc herniation with significant compression on the spinal cord, can be used to reduce a unilateral facet dislocation, generous removal of the anterior-inferior aspect of the cephalad vertebra, unilateral dislocations can be reduced by distracting vertebral bodies with caspar pins and then rotating the proximal pin towards the side of the dislocation, bilateral dislocations are reduced by placing converging Caspar pins (10-20 angle) and then compressing the ends together to unlock the facets, posterior directed force applied to rostral vertebral body with currette, alternatively, lamina spreaders applied to the endplates, not effective for reducing bilateral facet dislocations, often the PLL and posterior ligaments are disrupted, excessively large graft may be used to obtain a press-fit interbody graft, will demonstrate the facet joints being gapped posteriorly, over distraction also has risk of added spinal cord injury, when unable to reduce by closed or anterior approach, no anterior compression of spinal cord(no disc herniation), instrumentation performed with lateral mass screws, Penfield 4 inserted between facets and used to lever back into position, can remove the superior aspect of the superior facet of the caudad vertebrae to facilitate difficult reductions, distraction of the affected level between the affected spinous processes or lamina with use of lamina spreaders, usually have to fuse two levels due to inadequate lateral mass purchase at level of dislocation, go anterior first, perform discectomy, position plate but only fix plate to superior vertebral body, this way the plate will prevent graft kick-out but still allows rotation during the posterior reduction, this technique eliminates the need for a second anterior procedure, tissue trauma from injury increases risk of infection, unilateral dislocations treated with immobilization, treated with anterior diskectomy, reduction, and interbody fusion, higher risk in the multitraumatized patient, due to prolonged recumbency and need to tracheostomy, occurs in up to 11% of patients with cervical spine injuries, increased risk when injury involves lateral mass and transverse process, related to anterior reduction and fixation, primary repair with throacic surgeon upon identification, rarely result in meningitis if ther inner table of the skull is violated, lower probability of motor improvement with increasingly severe neurologic injury, increased age associated with decreased neurologic recovery, poor motor recovery potential with spinal cord hematoma. ttWKNZ, EuAtGY, UbN, xfu, vhRV, YVcBSM,
