bilateral vertebral artery occlusion after cervical Spine Fracture dislocation
World Neurosurgery, 2019Co-Authors: Ben A Strickland, Courtney S Lewis, Martin H PhamAbstract:Background Vertebral artery injury is known to potentially occur in conjunction with blunt cervical Spine trauma. Rarely, these injuries present bilaterally as complete occlusions. Twelve cases of bilateral vertebral artery occlusions after closed cervical Spine trauma have been described in the reported data, nearly all of which demonstrated signs and symptoms of vertebrobasilar insufficiency and ischemia. Case Description Our patient presented after a traumatic C5-C6 flexion–distraction injury that had resulted in bilateral locked facets and spinal cord injury and bilateral vertebral artery occlusions at the V1 segment. However, our patient did not show any cranial symptoms despite his neurovascular injury. Conclusions We present our patient's case as a rare illustration of a bilateral vertebral artery occlusion after blunt cervical Spine trauma without clinical vertebrobasilar ischemic sequelae.

the incidence of vertebral artery injury after midcervical Spine Fracture or subluxation
Neurosurgery, 1994Co-Authors: Brian K. Willis, Frank Greiner, William W Orrison, Edward C BenzelAbstract:TWENTY-SIX PATIENTS WITH blunt trauma of the cervical Spine, producing a subluxation from a «locked» or «perched» facet, facet destruction with evidence of instability, or a Fracture involving the foramen transversarium, underwent preoperative vertebral angiography to determine the incidence of vertebral artery injury. The cenical Spine injury in all the patients was deemed unstable and in need of surgical stabilization. Spinal cord injury was present in one-half of the patients studied. Vertebral artery injury was identified angiographically in 12 patients (46%). Occlusion of the vertebral artery near its origin or at the level of the spinal injury was identified in nine patients. An intimal flap, arterial dissection, and a pseudoaneurysm were identified in the remaining three patients

the incidence of vertebral artery injury after midcervical Spine Fracture or subluxation
Neurosurgery, 1994Co-Authors: Brian K. Willis, Frank Greiner, William W Orrison, Edward C BenzelAbstract:: Twenty-six patients with blunt trauma of the cervical Spine, producing a subluxation from a "locked" or "perched" facet, facet destruction with evidence of instability, or a Fracture involving the foramen transversarium, underwent preoperative vertebral angiography to determine the incidence of vertebral artery injury. The cervical Spine injury in all the patients was deemed unstable and in need of surgical stabilization. Spinal cord injury was present in one-half of the patients studied. Vertebral artery injury was identified angiographically in 12 patients (46%). Occlusion of the vertebral artery near its origin or at the level of the spinal injury was identified in nine patients. An intimal flap, arterial dissection, and a pseudoaneurysm were identified in the remaining three patients. The injury involved the left vertebral artery in all but three patients. In none of the patients did the vertebral artery injury clearly result in neurological dysfunction or other sequelae. After cervical Spine Fracture or dislocation, vertebral artery injury is more prevalent than commonly believed. The possibility of vertebral artery injury should be considered during the establishment of clinical management schemes for blunt trauma of the cervical Spine.

Spine Fracture prevalence in a nationally representative sample of us women and men aged 40 years results from the national health and nutrition examination survey nhanes 2013 2014
Osteoporosis International, 2017Co-Authors: Felicia Cosman, John H Krege, Anne C Looker, John T Schousboe, Bo Fan, Sarafrazi N Isfahani, John A Shepherd, Kelly Krohn, P Steiger, Kevin E WilsonAbstract:Spine Fracture prevalence is similar in men and women, increasing from 90 %) individuals were unaware of their Spine Fractures, lateral Spine imaging is needed to identify these women and men. Spine Fracture prevalence was threefold higher in individuals meeting NOF criteria for Spine imaging (∼1 in 7 undergoing VFA). Identifying Spine Fractures as part of comprehensive risk assessment may improve clinical decision making.

Osteoporosis International, 2017Co-Authors: Felicia Cosman, John H Krege, Anne C Looker, John T Schousboe, Bo Fan, Sarafrazi N Isfahani, John A Shepherd, Kelly Krohn, P Steiger, Kevin E WilsonAbstract:Summary Spine Fracture prevalence is similar in men and women, increasing from <5 % in those <60 to 11 % in those 70–79 and 18 % in those ≥80 years. Prevalence was higher with age, lower bone mineral density (BMD), and in those meeting criteria for Spine imaging. Most subjects with Spine Fractures were unaware of them.
