Anterior odontoid screw fixation for type II odontoid fracture is the Objective: 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 fusi...

PURPOSE To confirm the accuracy of the standard parameters of Chamberlain's line, McGregor's line, McRae's line, and Ranawat's line in the diagnosis of basilar impression in a normal Asian population using magnetic resonance imaging (MRI) scans of the craniocervical junction, and to evaluate the use of MRI in the initial diagnosis of basilar impression. METHODS We retrospectively reviewed MRI...

An odontoid fracture leading to Brown-Sequard syndrome (BSS) is an uncommon condition with only seven cases reported to date. To our knowledge, there are no reports of occurrence in paediatric patients. We report a paediatric odontoid fracture leading to Brown-Sequard syndrome (BSS) with satisfactory recovery following surgical treatment. Odontoid fractures may lead to Brown-Sequard syndrome in...

In 1969 the results of a survey of atlanto-axial subluxation in all seventy-six consecutive rheumatoid patients attending a clinic were published (Mathews, 1969). Abnormal separation of the odontoid process from the anterior arch of the atlas was found in nineteen (25%) patients and was found to be more common in patients with more serious forms of the disease. In addition, an abnormal vertical...

A 15-year-old girl with osteogenesis imperfecta (OI) and multiple bone fractures since early childhood presented with occipital headache. She had blue sclera and short neck (figure 1), right hypoglossal palsy, bilateral pyramidal tract signs, and gazeevoked nystagmus. Cervical MRI showed platybasia, basilar invagination, brainstem/high cord compression, and narrowing of upper cervical canal (fi...

Odontoid fractures type II according to Anderson and d’Alonzo are not uncommon in the elderly patients. Still, due to the paucity of evidence the published treatment guidelines are far from equivocal. This systematic review focuses on the published results of type II odontoid fracture treatment in the elderly with regard to survival, nonunion, and complications. After a systematic literature re...
