The objective of this study was to describe the treatments used in France in patients with hangman's fractures. When the subject was dropped, the head would be forced into hyperextension by the full weight of the . Therefore, if the patient's history and physical examination findings suggest serious underlying bony pathology (even if initial screening radiographs were negative for a fracture), the radiographs should be repeated, or, if warranted, more advanced diagnostic imaging should be performed. Type I fractures involve an avulsion fracture of the tip of the odontoid and are thought to occur as a result of rotation and lateral flexion, which causes injury to the alar ligaments. The most widely used classification is that of Levine and Edwards, based on lateral X-ray. Even if the initial radiographs are negative for a fracture, additional diagnostic imaging may be necessary for a small number of patients, because they may have undetected injuries that would necessitate medical referral and preclude physical therapy intervention. Screws that backed out were associated with lack of engagement of the distal cortex of the odontoid tip. This practical handbook covers the diagnosis and management of fractures in adults and children. Based on the specificity of this rule (specificity=43%; 95% CI=40%, 44%), it would not have been surprising if the radiographs were indeed negative for a fracture, even though this patient was positive according to the rule. The patient is usually discharged within 48 hours. Non-contrast CT scan is adequate for evaluation of the bony anatomy for fracture. Approximately 9% to 20% of all cervical fractures are dens fractures. The Journal of bone and joint surgery. Neurosurgery. The majority of Hangmans fractures may be successfully treated with external orthosis alone. A screw is then inserted through the drill guide. If pain doesn't resolve with supportive care, referral to a spine surgeon for removal of fragments is indicated. Many classification schemes for odontoid fractures have been proposed, but the most commonly used is that described by Anderson and DAlonzo in 1974. H In typical hangman's fracture the pedicles of the axis break symmetrically. 2017 [PubMed PMID: 29181200], Levine AM,Edwards CC, The management of traumatic spondylolisthesis of the axis. Benefits of surgical hangman's fracture treatment. A fracture can be a partial or complete break . The Canadian C-Spine Rule that helps determine when radiographs of the cervical spine may be indicated in patients with neck pain caused by trauma. The first reports of odontoid fixation were reported by Nakanishi in 198059 and Bohler in 1982.60 These early reports involved extensive neck dissection and were not widely adopted. CT scan does not directly evaluate the spinal cord, soft tissue, or ligamentous construct. There is also a close relationship of the transverse foramen, which carries the vertebral artery through the cervical spine, with the C2 pedicle/pars interarticularis, which may slightly weaken this area allowing for a fracture to occur. Hangman's fracture classification Levine/Effendi classification The system of Effendi et al as modified by Levine and others is widely used in grading adult HF (not applicable to peds). , Cook JM, Bolton JE. Found inside Page 282Table 6.6.4 Classification of hangman's fractures Type and frequency Displacement and angulation Stability Treatment I Most common <3mm No angulation Stable Collar, halo-vest II Common >3mm Wedge compression of anterior C3 Unstable The bone known as C2 is broken as it is the second bone down from [] The drill is now passed through the body of C2 to the fracture line, and after the surgeon is assured that the spine remains aligned, a hole is drilled to and then through the posterior apex of the odontoid. History should also entertain fracture risk factors such as osteoporosis, metastatic burden, or vitamin D deficiencies. If the fracture is unstable, awake fiberoptic intubation is necessary. Assoc Prof Craig Hacking and Assoc Prof Frank Gaillard et al. The first-line investigation with percutaneous angiography is overly aggressive.[6][7]. A 37-year-old woman drove her car into the back of a parked fire truck at an estimated speed of 40 to 45 miles per hour. The purpose of this case report is to describe a patient referred for physical therapy treatment of neck pain who had an underlying hangman's fracture that precluded physical therapy intervention. The treatment of odontoid fractures has long been a topic of debate. Found inside Page 162FIGURE 8-11 Dens fracture types and bilateral fractures of the pars interarticularis (hangman's fracture). Atlas fractures are treated with halo brace immobilization or surgical fixation, depending on whether they are present in The two most common hardware failures were screw backout and screw pullout. , Cassidy JD, Dupuis P, et al. METHODS: Ten patients with Hangman's fracture treated at our hospital from 1988 to 2001 were analysed. Successful repair of thefractured bone(s)can lead to excellent recoverieswith a good long-term prognosis. The purpose of this review is to provide an evidence-based analysis of the literature and clinical outcomes associated with the surgical and nonsurgical management of hangman's fractures. The majority of missed injuries (77%) were due to inadequate conventional radiographs. link. Furthermore, MRI evaluation is mandatory in evaluating the transverse ligament for the surgical decision matrix of non-displaced type II odontoid fractures. Diagnosis is made with CT of the cervical spine. The patient underwent anterior odontoid screw fixation and was discharged the next day. A concise, case-based clinical resource on the topic of imaging in spinal trauma, highly illustrated throughout. Plain film imaging demonstrates a fracture through the C2 pedicle . Nykoliation A hangman s fracture occurs specifically to . He was seen by his primary care physician 1 week after his motor vehicle accident as his emergency department physician recommended. A doctor will stabilize the head and neck to prevent further damage, using a neck brace. There is also close apposition of the spinal cord to the axis of rotation, which minimizes the torsional forces on the spinal cord that would be present if the cord were located more posteriorly. 1970 Apr [PubMed PMID: 5425648], SCHNEIDER RC,LIVINGSTON KE,CAVE AJ,HAMILTON G, [PubMed PMID: 14288425], Robinson AL,Olerud C,Robinson Y, Epidemiology of C2 Fractures in the 21st Century: A National Registry Cohort Study of 6,370 Patients from 1997 to 2014. Review the treatment of insufficiency fractures in detail. Pathogenesis, diagnosis, and imaging are discussed, along with nonsurgical and surgical management options. His recreational activities included skiing and golfing; however, he could not participate in these activities currently because of his neck pain and an inability to turn his neck. The treatment of odontoid fractures has long been a topic of debate. Among all the other types of cervical fracture, this is rendered as the most common one. focal neurological deficit (ie, focal neurological deficit that could be in a spinal cord or spinal nerve distribution: OR=58; 95% CI=12.0, 283.0). Narrowing of the C23 disk space and degenerative changes involving the lower cervical spine with osteophyte formation were noted. We also studied fracture patterns and their treatment outcomes. Although successful, these techniques are not strong in extension and axial rotation. A cervical fracture is a break in a vertebra (bone) in your neck. The patient was restrained by a seat belt. Loss of rotary motion at C1-2 is usually in the 50% range.51,52 Anterior procedures involve direct screw fixation across the fracture line. CT scan is the most important modality for determining fracture etiology and ruling out an injury regarding a C2 fracture. Although Mower et al11 did not define the clinical characteristics of the patients who had important bony cervical spine injuries missed on initial screening radiographs, Blackmore et al10 defined the clinical predictors of cervical spine fractures and quantified the degree to which each of these clinical predictors influenced the probability of a fracture. Found insideThis book covers a full spectrum of trauma-related conditions impacting the cervical spine and multidisciplinary interventions including minimally invasive surgery, neurointerventional techniques, reconstructive therapy with bone grafts or | Find, read and cite all the . Indications for surgery include irreducible or unstable fracture for which reduction is impossible; significant neurological deficit; previous nonunion; prolonged delay in treatment; injuries that preclude halo placement, including skull fractures and chest or facial injuries; and patients at high risk for nonunion, including the elderly and debilitated.4749. A minor compression fracture often can be treated with over-the-counter (OTC) pain medication and a cervical collar or brace to immobilize the neck until the break heals. A hand drill or power drill can be used. Found inside Page 34Complications of fracture treatment such as halo pin loosening , infection , and skull often complicate the treatment of hangman's fractures . A refined evaluation protocol for at-risk patients using reformatted CT scans has decreased the likelihood of missed injuries and assists in treatment decisions.

Methods Forty-one patients with hangman's fractures were identified from 105 patients with axis fractures between 2007 and 2013 . Surgical management of these injuries can be approached either anteriorly or posteriorly. It is important to remember that halo-vest orthosis is not very well tolerated in the elderly population, and therefore collar is recommended as first-line management.[8][9][10].
