Treatment of Dens Fractures with Posterior Transarticular Fixation.

JBJS Essent Surg Tech 2014 Jun 28;4(2):e10. Epub 2014 May 28.

Department of Traumatology, General Hospital Klagenfurt, Feschnigstrasse 11, 9020 Klagenfurt, Austria. E-mail address for A. Gstrein: E-mail address for E.J. Müller:

Introduction: Treatment of unstable dens fractures with posterior transarticular C1-C2 arthrodesis provides a biomechanically stable construct, even when poor bone quality is present, and a low rate of complications even in elderly patients; however, when this method of fixation is performed, cervical spine rotation is substantially reduced as compared with that associated with alternative fixation techniques.

Step 1 Positioning: Exact positioning of the patient and use of image intensifiers are mandatory to obtain appropriate anteroposterior and lateral views of C1 and C2.

Step 2 Surgical Approach: Use the modified technique of Magerl and Seemann, as it allows a less extensive approach to C1 and C2, and the drill can enter through two incisions at the level of T1. Read More

Occipitocervical Dislocation in Low-Energy Trauma.

Case Rep Orthop 2018 29;2018:3931525. Epub 2018 Nov 29.

Department of Orthopaedics & Sport Medicine, Harborview Medical Center, 325 Ninth Avenue Seattle, WA 98104, USA.

Traumatic occipitocervical dislocation (OCD) is described in the literature as a potentially fatal injury secondary to high-energy trauma. We describe a case of OCD occurring in a patient who sustained a ground-level fall whose only clinical symptom was posterior neck pain without neurologic compromise. Computed tomography (CT) and magnetic resonance imaging (MRI) were used to diagnose severe injury to the structurally important ligamentous complex that stabilizes the base of the skull to the spine, along with unstable fractures of the occipital condyle and C1.

Learning Curve in Surgical Treatment of Odontoid Fixation for a Series of Type II C2 Fractures.

Acta Neurochir Suppl 2019 ;125:325-327

Neurosurgical Clinic, AOUP "Paolo Giaccone", PostGraduate Residency Program in Neurologic Surgery, Department of Experimental Biomedicine and Clinical Neurosciences, School of Medicine, University of Palermo, Palermo, Italy.

The craniovertebral junction (CVJ) is a complex anatomical area upon which most of the motion of the upper cervical spine depends [1]. Because of its unique range of motion, the CVJ is subject to several types of traumatic injury; it has been shown that odontoid fractures are the most common ones in the general population and are the most common isolated spinal fractures [2]. Accounting for up to 18% of all cervical fractures, odontoid fractures are the most common ones in elderly patients [3], in whom they account for up to 60% of spinal cord injuries [4]. Read More

Blunt vertebral artery injury in occipital condyle fractures.

J Neurosurg Spine 2018 Nov;29(5):500-505

OBJECTIVEA shifting emphasis on efficient utilization of hospital resources has been seen in recent years. However, reduced screening for blunt vertebral artery injury (BVAI) may result in missed diagnoses if risk factors are not fully understood. The authors examined the records of blunt trauma patients with fractures near the craniocervical junction who underwent CTA at a single institution to better understand the risk of BVAI imposed by occipital condyle fractures (OCFs).

C1-C2 Fusion Versus Occipito-Cervical Fusion for High Cervical Fractures: A Multi-Institutional Database Analysis and Review of the Literature.

World Neurosurg 2018 Nov 30;119:e459-e466. Epub 2018 Jul 30.

Department of Neurosurgery, University of Illinois at Chicago, Chicago, Illinois, USA. Electronic address:

Objective: Type II odontoid fractures of the axis (C2) account for more than 20% of all cervical fractures. If an odontoid screw is contraindicated, the treatment approach for type II C2 fractures typically involves C1-C2 posterior fusion or occipito-cervical (O-C) fusion, each of which has distinct advantages and disadvantages. In this study, postoperative outcomes of C1-C2 fusion and O-C fusion for high cervical fractures were compared. Read More
