fracture c2 conséquences

Symptoms of a minor C2 fracture can include problems moving the neck, pain, swelling, tenderness, trouble swallowing, loss of feeling or a tingling sensation in the arms and legs,numbness or pain at the base of the head, double vision, or loss of consciousness. The most commonly utilized classification system for fracture of the odontoid process is the Anderson and D’Alonzo system, which identifies three types of fractures (1) (Fig. 2013 Jun 1. Previous publications find among odontoid fractures a distribution of 0–4% of type 1, 60–80% type 2, and 20–39% type 3 according to Anderson and D’Alonzo [10, 14, 17–19]. La réduction du déplacement entraîne une instabilité. 2009 May. Chen YR, Boakye M, Arrigo RT, Kalanithi PS, Cheng I, Alamin T, et al. Patients treated for C2 fractures at the university hospitals, but with a home address, at the time of injury, outside of the county were excluded. 24 (6):891-6. Gary Godorov, MD Staff Physician, Department of Emergency Medicine, Bellflower Medical CenterDisclosure: Nothing to disclose. The study was approved by the Regional Ethics Committee of Uppsala (number 2010/131/1).

Conservative treatment consists of closed reduction that is obtained under fluoroscopic guidance via application of compression and extension and is followed by halo-vest immobilization. After placement of bilateral C1and C2 screws and rods, one can place a cross link and compress the rods together, thereby reducing the fracture. Several treatment options are available for type II fractures, the first being conservative external fixation with halo or tong traction in weighted extension for 1 week. [20] Clinical and radiographic resultsshowed significantly less operating time and less blood loss in the percutaneous anterior screw fixation group. Generally, up to 50% of rotation is lost with these techniques. The details in various age and gender groups are presented in Table 1. The vertebrae enclose and protect the spinal cord. Odontoid fractures were classified, according to Anderson and D’Alonzo [14], into type 1, type 2, and type 3 referred to as O1, O2, and O3 in the text, tables, and figures, using the modified classification system by Grauer et al. Chapman J, Smith JS, Kopjar B, Vaccaro AR, Arnold P, Shaffrey CI, et al. The diagnostic procedure applied in this relatively recent cohort includes cervical computed tomography being more sensitive than plain radiographs, which were used in most previously published studies [24]. J Bone Joint Surg Am. There is no population-based data available on the C2 fracture subgroup distribution with regard to patient age. C2 Vertebrae Fracture Shilpakar et al looked at all treatment options and associated rates of complications. Suggest Treatment Indicate how you would treat this patient by completing the following brief survey. Doctors have used this term since 1965, when some doctors used it to describe traumatic spondylolisthesis involving the pars interarticularis of C2 on both sides. [19]  They concluded that all odontoid fractures without dislocation should be treated with rigid external immobilization and that all odontoid fractures with dens dislocation exceeding 5 mm should be considered for surgery. This study aims at establishing the distribution of C2 fracture subtypes, as well as the age and gender specific annual incidence of various C2 fracture subgroups, and to present the current treatment strategies related to these fractures in a well-defined regional cohort. The mean age for odontoid fractures was years, for Hangman’s fractures years, and for atypical fractures years of age. [15], distinguishing odontoid fracture type 2 and shallow type 3, could have led to a lower proportional estimate of odontoid fractures type 2. There were 183 odontoid fractures, 26 Hangman’s fractures, and 24 atypical C2 fractures. The study found that the risk of fusion failure was 37.5 times greater in patients in whom surgery was delayed for more than 1 week and 21 times greater in patients with a fracture gap of greater than 2 mm. Background: Cervical 2 (C2) fractures in the elderly are common, and the incidence of these fractures has been increasing. Morbidity and mortality of C2 fractures in the elderly: surgery and conservative treatment. Treatment of these fractures is cervical orthosis, unless more aggressive measures are needed to secure a concomitant unstable fracture. The hangman’s fracture refers to a break in a bone known as C2, because it is the second bone down from the skull in your cervical (neck) vertebrae. 1265365-overview Share cases and questions with Physicians on Medscape consult. The patients were subdivided according to age classes, <70 and ≥70 years. The observed annual increase of incidence of odontoid fractures can be caused by a detection bias. [Medline]. Beyond that, improved diagnostic protocols, that is, the standardised use of CT scans in cervical injury treatment algorithms, decreased the possibility of missed fractures, which artificially increases the incidence of fractures. Only patients with pure C2 body fractures were included in this study. Abnormal movement of neck bones or pieces of bone can cause a spinal cord injury resulting in loss of sensation, paralysis, or usually instant death. No patient in our dataset was referred with delay; therefore we consider the number of missed spinal injuries negligible. Wang J, Zhou Y, Zhang ZF, Li CQ, Zheng WJ, Liu J. Eur Spine J. Ying Z, Wen Y, Xinwei W, Yong T, Hongyu L, Zhu H, et al. Fracture des cervicales C1 et C2. [Full Text]. Conséquences d'une fracture des cervicales " Lorsqu'il n'y a pas d'atteinte neurologique, la récupération est généralement assez bonne " explique le chirurgien. During our radiographic analysis and patient history screening, no cases had to be excluded as false-positive, confirming the quality of diagnosis coding. Neurosurgery. If adequate results are not achieved after closed reduction and traction, open reduction with anterior cervical plating is the next step. 38 (13):1098-104. In this case, surgical reduction and stabilization is mandated and is accomplished with lateral mass plates, interspinous wiring, or bilateral oblique wiring. A dataset of all patients treated between 2002 and 2014 for C2 fractures was extracted from the regional hospital information system. Procedures, 2001 Over the investigated years there was change in odontoid fracture subgroup distribution. 2007 Jul. [Medline]. Levine and Edwards classification is used to classify hangman fractures of C2 (also known as traumatic spondylolisthesis of axis).. Aydinli U, Kara GK, Ozturk C, Serifoglu R. Surgical treatment of odontoid fractures with C1 hook and C2 pedicle screw construct. C2 fractures were classified into odontoid fractures types 1, 2, and 3, Hangman’s fractures types 1, 2, and 3, and atypical C2 fractures. The proportion of elderly ≥70 years decreased from 15.7% in 2002 to 14.9% in 2014. 2013. The currently available data on the distribution of C2 fracture subtypes is sparse. With only 26 cases in our cohort, the plotted distribution of Hangman’s fracture subtypes lacks detail (Figure 2). Society With regard to the treatment of odontoid type 3 fractures there is a consensus on nonsurgical treatment, such as a collar or halo-vest [37, 38]. Methods. • C2 fractures most common • Younger patients: C1 and C2 Hangman’s fractures more common • Odontoid fractures evenly distributed – Younger patients have higher energy injuries Ryan and Henderson Injury 1992 . The demographic changes may also have affected the incidence of C2 fractures. Patients that did not fulfil the criteria of any of these classification systems were classified as atypical C2 fractures—referred to as A. Complications secondary to posttraumatic degenerative changes may eventually warrant atlantoaxial arthrodesis. Cervical vertebrae support your head and allow your neck to bend and twist. There was a higher proportion of odontoid fractures type 3 among elderly compared to the younger age group (Figure 1). C1-C2 Fracture with atlantoaxial subluxation. 70 (5):1055-9; discussion 1059. . Effects of age group and gender on treatment allocation and C2 fracture distribution were tested with Chi-square test. • Tipo II: presenta un desplazamiento >4mm, una angulación >11º y alteración discal C2-C3. Malunion is a potential complication. 233 patients (female 51%, age years) were treated for a C2 fracture. A study of institutionalization in late life,”, A. Nourbakhsh, R. Shi, P. Vannemreddy, and A. Nanda, “Operative versus nonoperative management of acute odontoid type II fractures: a meta-analysis—clinical article,”, A. F. Joaquim and A. The currently available data on the distribution of C2 fracture subtypes is sparse. The proportion of O2 decreased compared to O3 from 2002 to 2014 in the age group ≥ 70 years (). osteogenesis imperfecta) and thus prone to fractures from forces that would be insufficient to cause fractures … Characteristics of the OD group were compared to the non OD group (Table2). 4—28-year-old man with atypical hangman’s fracture. Conneely M, Park J, Demos TC. Upper cervical spine injuries: a management of a series of 70 cases. A fracture of the C2 vertebra is known as a hangman’s fracture or axis vertebra fracture. Repeated imaging is used to monitor the healing process with a variable time course. [Medline]. Knowledge of the practice of the different types of C1-C2 and C2 screw fixations is indispensable. From 2002 to 2014 we could observe an increase in the odontoid fractures type 2 incidence, from 7 to 16 per 100,000 person-years. Se trata de una lesión estable, por lo que su tratamiento es la inmovilización con collarín rígido. Il peut y avoir des petites séquelles telles que des douleurs chroniques ou des troubles fonctionnels. This group comprises multiple fracture types and fracture mechanisms [9, 26]. C2 fractures can be subdivided into odontoid fractures, Hangman’s fractures, and atypical fractures [9]. Factors affecting this are amount and position of displacement, degree of angulation, ability to obtain and hold a reduced fracture, age of the patient, and tolerance to halo immobilization. However, in the age group ≥ 70, the annual incidences of O2 and O3 fractures together almost tripled from 7.4 per 100,000 person-years in 2002 to 22.1 per 100,000 person-years in 2014 (Figure 3). 2007 Jul. Annual incidence of odontoid fractures (all types) in patients ≥ 70 years (dotted), divided into subgroups of odontoid fracture type 2 (orange) and type 3 (grey) during the years 2002 to 2014. Neurosurgery. Management of acute odontoid fractures: operative techniques and complication avoidance. Spine (Phila Pa 1976). Cho DC, Sung JK. Your healthcare provider will talk to you about your medical history and recent injuries and do a physical exam. In this case, the patient has an upper cervical axial fracture of C2 as well as a lower cervical C6 fracture. 22 (2):91-5 2017, Article ID 8321680, 7 pages, 2017. https://doi.org/10.1155/2017/8321680, 1Department of Surgical Sciences, Uppsala University Hospital, Uppsala, Sweden, 2Stockholm Spine Center, Stockholm, Sweden, 3Department of Orthopaedics, Skåne University Hospital, Malmö, Sweden. Surgical options include C2 transpedicular screws and anterior cervical plating. Comparison of percutaneous and open anterior screw fixation in the treatment of type II and rostral type III odontoid fractures. Nizare el F, Abdelali B, Fahd DH, Yassad OM, Rachid G, Rachid el M, et al. B. Drabier, M. N. Hadley, and V. K. H. Sonntag, “Acute axis fractures: analysis of management and outcome in 340 consecutive cases,”, T. J. Choma, G. R. Rechtine, R. A. McGuire, and D. S. Brodke, “Treating the aging spine,”. The reason for this specific population development is most likely the urban nature of the included municipalities and the migration of the younger population towards cities in Sweden [30]. This study presents reliable subset proportions of C2 fractures in a prospectively collected regional cohort. Common hardware failures include screw bending and breaking, loosening of implants, and hardware failure secondary to osteoporotic bone. Nonunion and malunion are potential complications. 95 (8):729-35. If reduction is acceptable (with less than 4 mm of displacement and less than 10º of angulation), treatment progresses with halo-vest immobilization for 12-16 weeks. The 7 cervical vertebrae are called C1 through C7. This finding is not uncommon among spinal fractures [6, 7]. a)Lésions nerveuses. 2013. In the US there is a trend towards surgical management of these fractures [1, 12, 23, 27, 32–34]. C1 C2 Fracture Complications. Surgical treatment options for these fractures include C2 transpedicular screw fixation along with odontoid screw fixation. Neurosurgery. Three types of C2 odontoid fractures: type I is an oblique fracture through the upper part of the odontoid process; type II is a fracture occurring at the base of the odontoid as it attaches to the body of C2; type III occurs when the fracture line extends through the body of the axis.
