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...

REVIEW
Megan E Gornet, Michael P Kelly
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...

A rare case of atlantoaxial lateral mass joint interlocking secondary to traumatic posterolateral C1,2 complete dislocation associated with type II odontoid fracture is herein reported and the impact of atlantoaxial joint interlocking on fracture reduction discussed. A 72-year-old man presented with traumatic atlantoaxial lateral mass joint interlocking without spinal cord signal change, the diagnosis being confirmed by radiography and 3-D reconstruction digital anatomy. Posterior internal fixation was performed after failure to achieve closed reduction by skull traction...

Anterior odontoid screw fixation has been proved to be effective but technically challenging because the difficult approach is associated with high risks of screw malposition and damage to surrounding vital structures. Navigation techniques are therefore increasingly being used to improve safety and accuracy. However, no robot-assisted odontoid screw fixation has yet been reported. We here report a 61-year-old woman with a type II dens fracture on whom anterior odontoid screw fixation was performed under the guidance of a newly developed robotic system (TiRobot, co-designed by Beijing Jishuitan Hospital and TINAVI Medical Technologies)...

OBJECTIVE: To evaluate the long term C1-C2 fusion rates, fracture healing and functional outcomes in geriatric patients with type II odontoid fracture treated with posterior fixation with polyaxial C1 lateral mass screws and C2 pars screws. METHODS: Twenty-one consecutive patients between 2005 and 2011 with Anderson and D'Alonzo type II odontoid fracture underwent a posterior atlanto-axial fixation with polyaxial C1 lateral mass screws and C2 pars screws. A long-term clinical and radiological follow-up was achieved in all patients with a mean follow-up period of 53...

OBJECTIVE: We hypothesized that the entry site of the basivertebral vein into the basivertebral foramen of C2 might localize the subdental synchondrosis between the odontoid process and body of C2, which may be helpful for odontoid fracture classification. METHODS: Twenty-five dry adult C2 specimens underwent thin cut CT and were sectioned sagittally. The basivertebral foramen was then correlated to internal bony anatomy. 50 MRIs were reviewed and the location of the subdental synchondrosis determined...

AIMS: We performed a retrospective, comparative study of elderly patients with an increased risk from anaesthesia who had undergone either anterior screw fixation (ASF) or halo vest immobilisation (HVI) for a type II odontoid fracture. PATIENTS AND METHODS: A total of 80 patients aged 65 years or more who had undergone either ASF or HVI for a type II odontoid fracture between 1988 and 2013 were reviewed. There were 47 women and 33 men with a mean age of 73 (65 to 96; standard deviation 7)...

STUDY DESIGN: Retrospective review. PURPOSE: We retrospectively reviewed our patients with ankylosing spondylitis (AS) to identify their patterns of spinal fractures to help clarify management strategies and the morbidity and mortality rates associated with this group of patients. OVERVIEW OF LITERATURE: Because of the brittleness of bone and long autofused spinal segments in AS, spinal fractures are common even after minor trauma and often associated with overt instability...

STUDY DESIGN: Retrospective comparative clinical case series. OBJECTIVE: Burst C2 fractures are very rare. Treatment options include conservative treatment or fusion (anterior, posterior, or anterior and posterior). Anterior fusion addresses mainly hangman component. The bursting body usually needs posterior or combined anterior-posterior fusion, but both permanently sacrifice atlantoaxial motion. Can anterior-"first" approach preserve C1-C2 motion and restore function? METHODS: We report nine cases of burst C2 combined with C2-C3 spondylolisthesis and an odontoid fracture...

OBJECTIVE Type II odontoid fracture is a common injury among elderly patients, particularly given their predisposition toward low-energy falls. Previous studies have demonstrated a survival advantage following early surgery among patients older than 65 years, yet octogenarians represent a medically distinct and rapidly growing population. The authors compared operative and nonoperative management in patients older than 79 years. METHODS A single-center prospectively maintained trauma database was reviewed using ICD-9 codes to identify octogenarians with C-2 cervical fractures between 1998 and 2014...

OBJECTIVE As odontoid process fractures become increasingly common in the aging population, a technical understanding of treatment approaches is critical. 3D image guidance can improve the safety of posterior cervical hardware placement, but few studies have explored its utility in anterior approaches. The authors present in a stepwise fashion the technique of odontoid screw placement using the Medtronic O-arm navigation system and describe their initial institutional experience with this surgical approach...
