✓ A retrospective study was made of 173 cases of acute cervical spine injury with halo vest management to compare initial injury features with outcome. The object was to determine whether a mathematical model could be developed enabling a prediction to be made at the time of the initial assessment as to the probability of success or failure of conservative management using the halo vest alone, and thus perhaps avoid lengthy, unsuccessful treatment. Patients with facet joint dislocation were found to form a distinct subgroup of the injury population. Of the 70 patients in this subgroup, 44% achieved stability with the halo vest alone, but half of these had a “poor anatomical result.” No mathematical model or associated injury features could be found to assist in the outcome prediction in this subgroup. Of the 103 patients without facet joint dislocation, 70% achieved stability with the vest alone and over 75% of these had a “good anatomical result.” A useful model of outcome prediction was found for this subgroup by logistic regression analysis; the two most important predictors in the model were the amount of subluxation and the degree of angulation in the sagittal plane.

✓ A 10-year-old boy had a sore throat, followed in 4 weeks by acute rheumatic fever and in 6 weeks by atlanto-axial dislocation. Reduction of the dislocation by means of a halo vest relieved his pain, but the cervical spine remained unstable after 3 months of immobilization and required an occiput-C1–2 fusion and rib graft to stabilize the atlanto-axial joint. This is the eighth reported case of atlanto-axial dislocation associated with acute rheumatic fever. The features of previous cases are summarized and the clinical aspects, mechanisms, diagnosis, and treatment of atlanto-axial dislocation are reviewed.

Object. Confirmation of cervical spine stability is difficult to obtain in the comatose or obtunded trauma patient. Concurrent therapies such as endotracheal intubation and the application of rigid cervical collars diminish the utility of plain radiographs. Bony as well as supportive soft-tissue structures must be evaluated before the cervical spine can be determined to be uninjured. Although major injuries to extradural soft-tissue structures in the awake trauma patient are frequently excluded by physical examination, when the patient is obtunded the physical examination may be unreliable. Therefore, an enhanced diagnostic method for the evaluation of soft-tissue injury is desirable. The authors conducted a study in which magnetic resonance (MR) imaging was used as such a method to assess posttraumatic spinal stability in the comatose or obtunded patient. Methods. Early, limited (sagittal T1- and T2-weighted) MR imaging was performed posttruama in 121 patients to assess soft-tissue injury. In all patients the mechanism of injury potentially could be associated with cervical spine instability, and each patient was endotracheally intubated because of head injury or severe multisystem injuries. All patients underwent imaging studies within 48 hours of injury and were either treated or cleared and spinal precautions were discontinued. Patients were excluded from this study if they had an obvious cervical spine injury identified on the initial radiographic studies or if they were determined to be too medically unstable to undergo MR imaging within the acute period (<48 hours postinjury). Thirty-one (25.6%) of the 121 patients were found to have sustained significant injury to the paravertebral ligamentous structures, the disc interspace, or the bony cervical spine. These injuries were undetected by plain radiography. The other 90 patients (74.4%) were determined within 48 hours not to have sustained a soft-tissue injury. Eight patients (6.6%) ultimately underwent surgery to treat the cervical spine injury, and MR imaging was the first test that identified the injury in each of these patients. There were no complications related to imaging procedures. Conclusions. Sagittal T1- and T2-weighted MR imaging appears to be a safe, reliable method for evaluating the cervical spine for nonapparent injury in comatose or obtunded trauma patients. In the early postinjury period, nursing and medical care are thereby facilitated for patients in whom occult injury to the spine is ruled out and for whom those attendant precautions are unnecessary.

✓ Because it is often difficult to diagnose accurately the structurally intact cervical spine after acute trauma, a series of patients was evaluated with magnetic resonance (MR) imaging to assess its efficacy for the evaluation and clearance of the cervical spine in a trauma victim in the early posttrauma period. Ultralow-field MR imaging was used to evaluate 174 posttraumatic patients in whom physical findings indicated the potential for spine injury or minor radiographic findings indicated injury. This series includes only those patients who did not appear to harbor disruption of spinal integrity on the basis of a routine x-ray film. None had clinically obvious injury. Of the 174 patients, 62 (36%) had soft-tissue abnormalities identified by MR imaging, including disc interspace disruption in 27 patients (four with ventral and dorsal ligamentous injury, three with ventral ligamentous injury alone, 18 with dorsal ligamentous injury alone, and two without ventral or dorsal ligamentous injury). Isolated ligamentous injury was observed in 35 patients (eight with ventral and dorsal ligamentous injury, five with ventral ligamentous injury alone, and 22 with dorsal ligamentous injury alone). One patient underwent a surgical fusion procedure, 35 patients (including the one treated surgically) were placed in a cervical collar for at least 1 month, and 27 patients were placed in a thermoplastic Minerva jacket for at least 2 months. All had a satisfactory outcome without evidence of instability. The T2-weighted sagittal images were most useful in defining acute soft-tissue injury; axial images were of minimal assistance. Posttraumatic soft-tissue cervical spine injuries and disc herniations (most likely preexisting the trauma) are more common than expected. A negative MR image should be considered as confirmation of a negative or “cleared” subaxial cervical spine. Diagnostic and patient management algorithms may be appropriately tailored by this information. Thus, MR imaging is useful for early acute posttrauma assessment in a very select group of patients.

Object. The authors tested the hypothesis that initial alignment of the head—neck complex affects cervical spine injury mechanism, trauma rating, injury classification based on stability, and fracture pattern. Methods. Thirty intact human cadaveric head—neck complexes were prepared by fixing the thoracic end in polymethylmethacrylate. The cranium was unconstrained. The initial spinal alignment was described in terms of eccentricity, defined as the anteroposterior position of the occipital condyles with respect to the T-1 vertebral body. The specimens were subjected to impact loading delivered using an electrohydraulic testing device. Outcomes after injury were identified using radiography and computerized tomography. The mechanisms of injury were classified according to fracture pattern into compression—extension, compression—flexion, hyperflexion, and vertical compression. Trauma was graded according to the Abbreviated Injury Scale rating system. Based on clinical assessment, injuries were classified as stable or unstable. Injuries were also classified into bone fracture or nonfracture groups. Analysis of variance tests were used to determine the influence of eccentricity on spinal injury outcomes. Eccentricity significantly influenced the mechanism of injury (p < 0.0001), trauma rating (p < 0.005), and fracture (p < 0.0001) classification. Statistically significant differences, however, were not apparent when the classification of injury was based on stability considerations. Conclusions. Spinal alignment is a strong determinant of the biomechanics of impact-induced cervical spine injury.

✓ A case of cervical spine injury related to bungee jumping is presented. Surgical intervention resulted in resolution of the patient's quadriparesis. The incidence of serious injury connected with this pastime is not inconsiderable, and it is recommended that safer jumping practices be followed. Inspection of bungee equipment and certification of instructors is now voluntary but should be mandated. Jumping heights should be limited and the use of air cushions encouraged.

Object. Diagnosing and managing cervical spine trauma in head-injured patients is problematic due to an altered level of consciousness in such individuals. The reported incidence of cervical spine trauma in head-injured patients has generally ranged from 4 to 8%. In this retrospective study the authors sought to define the incidence of cervical injury in association with moderate or severe brain injury, emphasizing the identification of high-risk patients. Methods. The study included 447 consecutive moderately (209 cases) or severely (238 cases) head injured patients who underwent evaluation at two Level 1 trauma centers over a 40-month period. Of the 447 patients, 24 (5.4%) suffered a cervical spine injury (17 men and seven women; mean age 39 years; median Glasgow Coma Scale [GCS] score of 6, range 3–14). Of these 24 patients, 14 (58.3%) sustained spinal cord injuries (SCIs), 14 sustained injuries in the occiput—C3 region, and 10 underwent a stabilization procedure. Of the 14 patients with SCIs, nine experienced an early hypotensive and/or hypoxic insult. Regarding the mechanism of injury, cervical injuries occurred in 21 (8.2%) of 256 patients involved in motor vehicle accidents (MVAs), either as passengers or pedestrians, compared with three (1.6%) of 191 patients with non-MVA-associated trauma (p < 0.01). In the subset of 131 MVA passengers, 13 (9.9%) sustained cervical injuries. Patients with an initial GCS score less than or equal to 8 were more likely to sustain a cervical injury than those with a score higher than 8 (odds ratio [OR] 2.77, 95% confidence interval [CI] = 1.11–7.73) and were more likely to sustain a cervical SCI (OR 5.5, 95% CI 1.22–24.85). At 6 months or more postinjury, functional neurological recovery had occurred in nine patients (37.5%) and eight (33.3%) had died. Conclusions. Head-injured patients sustaining MVA-related trauma and those with an initial GCS score less than or equal to 8 are at highest risk for concomitant cervical spine injury. A disproportionate number of these patients sustain high cervical injuries, the majority of which are mechanically unstable and involve an SCI. The development of safer and more rapid means of determining cervical spine integrity should remain a high priority in the care of head-injured patients.

✓ The authors present the case of a 15-year-old Jehovah's Witness with a hematocrit level of 19% who was 4 months pregnant and had a two-level spondyloptotic cervical spine fracture. The patient was transferred to Georgetown University Medical Center with C-5 quadriplegia 3 weeks after having been injured in an automobile collision. The neurosurgical issues in this case included addressing a rare cervical spine injury, assessing and treating a vertebral artery injury, and performing surgery on a pregnant minor with severe anemia who held strong Jehovah's Witness beliefs. An ethics consultation was convened to determine the validity of a pregnant minor's refusal to undergo transfusion on the grounds of her religious beliefs. This case illustrates the potential benefits of thorough technical and ethical evaluations and reveals how they may contribute to the delivery of care in complex neurosurgical cases. To the authors' knowledge, this is the first two-level spondyloptotic cervical spine fracture dislocation to be reported in the literature. The added complexities of the case, given that the patient was an anemic, adolescent, pregnant Jehovah's Witness who refused blood transfusion, also appear to be unprecedented.

✓ The indications for surgical fusion, as opposed to halo fixation, in the management of cervical spine injury are still unclear. At St. Louis University Medical Center a conservative protocol has been adopted to treat almost all cervical spine fractures with halo fixation. To determine what factors have contributed to failure of halo fixation, the records and radiographs of all patients with cervical spine injuries who were treated at that institution between 1984 and 1986 were reviewed. During this interval, 124 patients were treated, consisting of 93 men and 31 women between 6 and 94 years old. Of these, 15 (12%) had cervical fusion without preoperative halo device application. This group included eight patients with old injuries and delayed diagnosis, three with nonreducible locked facets, and four with miscellaneous indications. The remaining 109 patients were treated with halo vests. Four died before completing the 3-month standard treatment. Of those completing the treatment, 48 had C1–2 level injuries and 57 had C3–T1 level injuries. Sixteen patients (15%) failed their halo treatments and required surgical fusion: eight while still in halo fixation and eight after they had completed treatment with a halo device. Failure of halo treatment was indicated by recurrent dislocation in 13 patients and increased neurological deficit in three. Thirteen of the patients who failed treatment had C3–T1 injuries and three had C1–2 injuries. Of 27 patients with odontoid fractures, only two (7.4%) failed halo fixation. There were no failures in 11 patients with hangman's fractures. Of the 57 patients with C3–T1 injuries, 13 (23%) failed treatment, nine of whom had locked or “perched” facets. The factors causing failure of halo fixation were analyzed. The overall success rate was 85%, suggesting that the halo vest can be used to treat most patients with cervical spine injuries. Under certain circumstances (in the presence of old injuries, difficult reduction, or locked or “perched” facets), surgery may be indicated to avoid unnecessary delay in definitive management.
