The discovery of a craniocervical junction malformation requires management in three steps: (1) The patterns must be recognized using tomographic measurements (Chamberlain's line, Wackenheim's line). Dynamic flexion-extension studies are necessary to assess stability or instability. Stable patterns range from platybasia to basilar invagination, with gradual(More)
1 Anonymous Abstract. A new anatomical database, My Corporis Fabrica (MyCF), is presented. It extends the reference anatomical ontology FMA (the Foundational Model of Anatomy) with the possibility to coherently integrate 3D geometrical data, as well as biomechanical parameters. The purpose of this extension is to allow the user to intuitively create a(More)
OBJECTIVE The goal of this study was to determine the rate of recurrent vestibular schwannoma after a total removal via the translabyrinthine approach. PATIENTS Between 1973 and 1995, 346 patients were operated on by a translabyrinthine approach. Ninety-one patients were included in a retrospective study for follow-up of 5 years or longer. RESULTS The(More)
The linear nucleus (Li) is a prominent cell group in the caudal hindbrain, which was first described in a study of cerebellar afferents in the rat by [Watson, C.R.R., Switzer, R.C. III, 1978. Trigeminal projections to cerebellar tactile areas in the rat origin mainly from N. interpolaris and N. principalis. Neurosci. Lett. 10, 77-82.]. It was named for its(More)
BACKGROUND The Foundational Model of Anatomy (FMA) is the reference ontology regarding human anatomy. FMA vocabulary was integrated into the Health Multi Terminological Portal (HMTP) developed by CISMeF based on the CISMeF Information System which also includes 26 other terminologies and controlled vocabularies, mainly in French. However, FMA is primarily(More)
Accurate localization of the target is essential to reduce morbidity during brain tumor removal interventions. Yet, image-guided neu-rosurgery faces an important issue for large skull openings where brain soft-tissues can exhibit large deformations in the course of surgery. As a consequence of this " brain-shift " the pre-operatively acquired images no(More)
BACKGROUND Multiple models of anatomy have been developed independently and for different purposes. In particular, 3D graphical models are specially useful for visualizing the different organs composing the human body, while ontologies such as FMA (Foundational Model of Anatomy) are symbolic models that provide a unified formal description of anatomy.(More)
A number of knowledge management systems have been developed to allow users to have access to large quantity of neuroanatomical data. The advent of three-dimensional (3D) visualization techniques allows users to interact with complex 3D object. In order to better understand the structural and functional organization of the brain, we present Neuroanatomical(More)
STUDY DESIGN A case of traumatic rotatory dislocation associated with odontoid fracture is reported. OBJECTIVES To report a rare case of traumatic rotatory dislocation associated with odontoid fracture, and to discuss the mechanism underlying spinal instability and management. SUMMARY OF BACKGROUND DATA This case is a cross between traumatic rotatory(More)
