Objective: To evaluate the correlation between the treatment, the characteristics of the lesions and the clinical outcome of patients with traumatic injuries to the craniocervical junction. Methods: This was a retrospective study of patients treated conservatively or surgically between 2010 and 2013 with complete data sets. Results: We analyzed 37 patients, 73% were men with mean age of 41.7 years. Of these, 32% were submitted to initial surgical treatment and 68% received conservative treatment...

BACKGROUND: Multiple fractures of the atlas and axis are rare. The management of multiple fragment axis fractures and unstable atlas fractures is still challenging for the spinal surgeon. There are no published reports of similar fractures with 3-part fracture of axis associated with an unstable atlas fracture. CASE SUMMARY: We present a patient with concurrent axis and atlas fractures, which have not been reported. The patient suffered hyperextension injury with neck pain and numbness of the bilateral upper extremity associated with weakness after a 2-m fall...

The surgical fracture fixation of the odontoid process (dens) of the second cervical vertebra (C2/axis) is a challenging procedure, particularly in elderly patients affected by bone loss, and includes screw positioning close to vital structures. The aim of this study was to provide an extended anatomical knowledge of C2, the bone mass distribution and bone loss, and to understand the implications for anterior screw fixation. 120 standard clinical quantitative computed tomography (QCT) scans of the intact cervical spine from 60 female and 60 male European patients, aged 18-90 years, were used to compute a three-dimensional statistical model and an averaged bone mass model of C2...

AIMS: Rates of mortality as high as 25% to 30% have been described following fractures of the odontoid in the elderly population. The aim of this study was to examine whether easily identifiable variables present on admission are associated with mortality. PATIENTS AND METHODS: A consecutive series of 83 elderly patients with a fracture of the odontoid following a low-impact injury was identified retrospectively. Data that were collected included demographics, past medical history and the results of blood tests on admission...

Fractures of the odontoid process seem to have an unclear and not well-understood behavior. This is well demonstrated in the literature as there is a disagreement in many fields, including the patterns of fractures, the percentage of pseudarthrosis or the appropriate treatment that is required. This situation makes the fracture itself a "challenging" one. Indeed, despite the existence of extensive literature, there are still many unresolved problems concerning these fractures. We recognize six main classification schemes of the odontoid process fractures which clearly demonstrate the presence of differences but, also, the disadvantages that these classifications are related to...

BACKGROUND: Establishing a clear treatment paradigm for octogenarians with type II odontoid fractures in hampered by a literature replete with level III articles. METHODS: In the study by Graffeo et al., the authors evaluated 111 patients over the age of 79 (average age: 87) with type II odontoid fractures undergoing nonoperative (94 patients) vs. operative intervention (17 total; 15 posterior and 2 anterior). They studied multiple variables and utilized several scales [abbreviated injury scale (AIS), injury severity score (ISS), and the Glasgow coma scale (GCS)] to determine the outcomes of nonoperative vs...

Objective: Anterior odontoid screw fixation for type II odontoid fracture is the ideal management option. However in the context of unavailability of an O-arm or neuro-navigation and poor images from the available C-arm may be an obstacle to ideal trajectory and placement of the odontoid screw. We herein detail  our surgical technique so as to ensure a correct trajectory and subsequent good fusion in Type II odontoid fractures. This may be advantageous  in clinical set ups lacking state of the art facilities...

STUDY DESIGN: Retrospective cohort analysis. OBJECTIVE: To compare 30-day perioperative clinical outcomes of surgical odontoid stabilization by an anterior or posterior operative approach in elderly patients. SUMMARY OF BACKGROUND DATA: Surgical stabilization of odontoid fractures is superior to nonoperative management in geriatric patients. How elderly patients with odontoid fractures fare after anterior and posterior approaches, however, is not well defined...

Background: Treatment of type II fractures of the odontoid process is still controversial. Besides conservative treatment, there are surgical options, including anterior screw fixation, as first described by Böhler and Magerl, or procedures using a dorsal approach. Many authors prefer dorsal fusion of C1 and 2, due to the reliable, biomechanical stability. In this context, pedicle screw fixation, as described by Harms, and transarticular screw fixation of the atlantoaxial joints, as described by Magerl, have to be mentioned...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To evaluate the utilization and effectiveness of halo-vest (HV) immobilization for type II odontoid fractures from 2004 to 2014. SUMMARY OF BACKGROUND DATA: Controversy persists regarding the optimal treatment method for odontoid fractures in the elderly. Management options include immobilization in a cervical orthosis, HV immobilization, and operative intervention. Over the past decade, high mortality and morbidity rates have been reported following HV immobilization in this patient population...

Odontoid fractures are the most common cervical fracture type among the elderly population. Several treatment options exist for these patients, ranging from immobilization with a semirigid orthosis to surgical arthrodesis. This report reviews the key points in the management of odontoid fractures in the aged patient, including diagnosis, the various forms of conservative therapies, and the options for surgical intervention.

OBJECTIVE: To analyze the characteristics of type-II odontoid fractures (TII-OF); the clinical and radiographical factors that influence surgical planning in eight Latin American centers. METHODS: Retrospective chart review of 88 patients reported with TII-OF between 2004 and 2015 from eight Latin American centers. The studied parameters were: (I) demographic data, (II) cause of fracture, (III) clinical and neurologic presentation, (IV) characteristics of the fracture (degree of odontoid displacement, displacement of the odontoid relative to the C2 body, anatomy of the fracture line, the distance between fragments, presence of comminution, contact area between the odontoid and the C2 body, (V) type of treatment, (VI) clinical and radiographic outcome...

INTRODUCTION: The aim of this systematic review was to compare the halo and hard collar in the management of adult odontoid fractures. METHODS: Systematic and independent searches on MEDLINE (PubMed) and the Cochrane database. INCLUSION CRITERIA: (1) clinical outcomes, (2) in adults (≥18), (3) with odontoid fractures, (4) immobilised using a halo or hard collar, (5) in multiple (>5) patients. Treatment failure rates were calculated as the proportion requiring operative intervention...

OBJECTIVE The goal of this study was to demonstrate the clinical and technical nuances of a minimally invasive, dorsolateral, tubular approach for partial odontoidectomy, autologous bone augmentation, and temporary C1-2 fixation to treat dens pseudarthrosis. METHODS A cadaveric feasibility study, a 3D virtual reality reconstruction study, and the subsequent application of this approach in 2 clinical cases are reported. Eight procedures were completed in 4 human cadavers. A minimally invasive, dorsolateral, tubular approach for odontoidectomy was performed with the aid of a tubular retraction system, using a posterolateral incision and an oblique approach angle...

Fractures of the second cervical vertebra (C2, axis) are common in adult spine surgery. Those fractures occurring in younger adult patients are often associated with high-energy mechanism trauma, resulting in a "Hangman's Fracture." Management of these fractures is often successful with nonoperative means, though surgery may be needed in those fractures with greater displacement and injury to the C2-C3 disc. Older patients are more likely to sustain fractures of the odontoid process. The evidence supporting surgical management of these fractures is evolving, as there may be a mortality benefit to surgery...
