The purpose of our study is to evaluate the results of our surgical series and to compare them with the literature. Materials and Methods  In this monocentric retrospective study of over three years (June 2019-May 2022), all the patients with traumatic injuries of the upper cervical spine with a surgical treatment and a minimum of 12 months follow-up were included...

BACKGROUND CONTEXT: Type II odontoid fractures (OF) are among the most common cervical spine injuries in the geriatric population. However, there is a paucity of literature regarding their epidemiology. Additionally, the optimal management of these injuries remains controversial, and no study has evaluated the short-term outcomes of geriatric patients presenting to emergency departments (ED). PURPOSE: This study aims to document the epidemiology of geriatric patients presenting to EDs with type II OFs and determine whether surgical management was associated with early adverse outcomes such as in-hospital mortality and discharge to skilled nursing facilities (SNF)...

BACKGROUND: Odontoid fractures are found in two age groups. In younger patients, they occur following traffic accidents, falls from a height and during sports. In older patients with poor bone quality, they are usually caused by falls from one's own height. Most fractures are stable and do not require surgical treatment. Unstable, severely displaced fractures with neurological deficits require surgical treatment. The aim of the study was to evaluate the surgical and functional outcomes of treatment of odontoid fractures with a cannulated screw...

INTRODUCTION AND IMPORTANCE: Odontoid fracture (OF) is among the most common and challenging cervical spine fractures in regards to the treatment and surgical approach. Atlanto-axial dislocation (AAD) is considered a significant complication after failed non-surgical treatment of OF. Traditionally, it requires anterior odontoidectomy followed by posterior C1-C2 reduction and fusion. In latest studies, Atlanto-axial joint (AAJ) remodeling in a posterior-only approach has got attention...

BACKGROUND: To evaluate the feasibility of treating odontoid fractures in the Chinese population with two cortical screws based on computed tomography (CT) scans and describe a new measurement strategy to guide screw insertion in treating these fractures. METHODS: A retrospective review of cervical computed tomographic scans of 128 patients (aged 18-76 years; men, 55 [43.0%]) was performed. The minimum external transverse diameter (METD), minimum external anteroposterior diameter (MEAD), maximum screw length (MSL), and screw projection back angle (SPBA) of the odontoid process were measured on coronal and sagittal CT images...

STUDY DESIGN: Retrospective Review of a National Database. INTRODUCTION: By utilizing a national database, this study aims to quantify the predictors of 30-day mortality after odontoid fixation and guide appropriate management for patients in whom the choice between operative and non-operative management is unclear. METHODS: The American College of Surgeons National Surgical Quality Improvement Database was queried using Current Procedural Terminology (CPT) codes and International Classification of Disease (ICD) codes to identify patients 60 or older who underwent surgical fixation of an odontoid fracture from 2005 to 2020...

BACKGROUND: Different treatment options are discussed for geriatric odontoid fracture. The aim of this study was to compare the treatment options for geriatric odontoid fractures. METHODS: Included were patients with the following criteria: age ≥ 65 years, identification of seniors at risk (ISAR score ≥ 2), and odontoid fracture type A/B according to Eysel and Roosen. Three groups were compared: conservative treatment, surgical therapy with ventral screw osteosynthesis or dorsal instrumentation...

BACKGROUND: Type 2 odontoid fractures with posterior displacement are rare. Most acute cases reported in the literature are readily reduced with traction alone. Here, we reviewed the management of a chronic, posteriorly displaced odontoid fracture that was managed with a unique posterior reduction maneuver. CASE DESCRIPTION: A 58-year-old male with a chronic type 2 retro-odontoid displaced fracture was managed with traction and an anterior force applied to the displaced odontoid fragment using rods attached to bilateral C1 lateral mass screws...

The autosomal dominant spondylometaphyseal dysplasia Sutcliff type or corner fracture type FN1-related is characterized by a combination of metaphyseal irregularities simulating fractures ("corner fractures"), developmental coxa vara, and vertebral changes. It is linked to heterozygous mutations in FN1 and COL2A1. Vertebral changes as delayed vertebral ossification, ovoid vertebral bodies, anterior vertebral wedging, and platyspondyly have been observed in this condition, while odontoid abnormalities have not been reported...

OBJECTIVE: Odontoid fractures are the most common fracture of the cervical spine in adults older than 65 years of age. Fracture management remains controversial, given the inherently increased surgical risks in older patients. The objective of this study was to compare fusion rates and outcomes between operative and nonoperative treatments of type II odontoid fractures in the older population. METHODS: A systematic literature review was performed to identify studies reporting the management of type II odontoid fractures in patients older than 65 years from database inception to September 2022...

The aim of this study was to compare in-hospital mortality of three procedures -halo-vest immobilization, anterior spinal fixation (ASF), and posterior spinal fixation (PSF)- in the treatment of elderly patients with isolated C2 odontoid fracture. We extracted data for elderly patients who were admitted with C2 odontoid fracture and treated with at least one of the three procedures (halo-vest immobilization, ASF, or PSF) during hospitalization. We conducted a generalized propensity score-based matching weight analysis to compare in-hospital mortality among the three procedures...

BACKGROUND: Odontoid fractures are common cervical spine fractures; however significant controversy exists regarding their treatment. Risk factors for failure of conservative therapy have been identified, however no predictive risk score has been developed to aid in decision making. METHODS: A retrospective review was conducted of all patients evaluated at a level one trauma center. Patients identified with Type II Odontoid Fractures as classified by the D'Alonzo Classification system who were treated with external orthosis were included in analysis...

INTRODUCTION: Although various conservative and surgical treatment methods have been proposed, treatment options for patients with odontoid fractures remain controversial. This study was conducted to determine some demographic and radiological measurement parameters that can predict treatment options in patients with odontoid fractures. MATERIALS AND METHODS: The patients were separated into the surgery (-) group ( n = 9) and the surgery (+) group ( n = 10). Patient data were recorded of age, gender, type of odontoid fracture, morphological measurement results obtained from computed tomography images, treatment regimens, duration of stay in the hospital, and mortality rate...

INTRODUCTION: The prevalence of trauma is increasing in the geriatric population. The optimal therapy for type II odontoid fractures in the elderly is controversial. This study aims to assess the morbidity and mortality associated with odontoid fractures in octogenarians undergoing C1/C2 posterior screw fixation and describe the perioperative and post-operative complications and risk factors associated with mortality. MATERIALS AND METHODS: Electronic medical records from a single institution pertaining to the period between September 2005 and December 2020 were retrieved...

OBJECTIVE: To evaluate the biomechanical stability of anterior transarticular crossing screw (ATCS) and compare it with anterior transarticular screw (ATS) which may provide basic evidence for clinical application. METHODS: Eight human fresh cadaveric specimens (occiput-C4) were tested with 5 conditions including the intact status, the injury status (type II odontoid fracture), the injury+ATS fixation status (traditional bilateral ATS fixation); the injury+unilateral ATCS fixation status; and the injury+bilateral ATCS fixation status...

Geriatric odontoid fractures are some of the most common spine injuries in our aging population, and their prevalence is only continuing to increase. Despite several investigational studies, treatment remains controversial and there is limited conclusive evidence regarding the management of odontoid fractures. These injuries typically occur in medically complex and frail geriatric patients with poor bone quality, making their treatment particularly challenging. In this article, we review the evidence for conservative management as well as surgical intervention and discuss various treatment strategies...

The purpose of the study was to determine the bone mineral densities (BMDs) of the C1 and C2 vertebrae and discuss their implications for autonomous vehicle environments and vulnerable road users. Using quantitated computed tomography (QCT), the BMDs were obtained at eight regions for the C1 vertebra and seven regions for the C2 vertebra. The spine surgeon author outlined the boundaries of each region, and nine elderly female human cadaver specimens were used. The regions were based on potential stabilization locations for fracture fixation...

BACKGROUND: Odontoid fractures in association with a C1-C2 rotatory luxation reports are seldomly found over the literature. The fusion between the lateral mass of C1 and C2 could be of interest to ensure adequate treatment in these particular cases. OBJECTIVE: We report 23 cases where there is coexistence of an odontoid fracture and rotatory subluxation, which were treated surgically, using cages between C1-C2 or just traditional Harms-Goel technique. We evaluated the radiological fusion rate, reoperation rate and complications...
