[A case of unilateral dislocation of C3 right facet joint treated with lateral mass plating]. / Fracture-séparation du massif articulaire droit de la troisième vertèbre cervicale traitée par vissage des masses latérales.

Facet joint dislocations of the cervical spine are distractive-flexion injuries that account for 6 to 10 % of traumatic lesions of the subaxial cervical spine. Distractive-flexion injuries of the cervical spine were classified into four stages by Allen and Fergusson. These unstable lesions predominate at the fifth and sixth levels and all aspects of their management are subject to controversy, including their classification. Attempting reduction before surgery, performing MRI before or after closed reduction, choosing between surgery and external contention, the anterior versus the posterior approach are still matters of controversy between experts. The authors report a stage 2 distractive-flexion injury of the right facet joint of the third cervical vertebra treated by lateral mass plating as described by Roy-Camille (1995).

[Report of the World Federation of Neurosurgical Societies (WFNS) international course and Cameroon Neurosurgery Society Congress (CNS) Yaoundé (Cameroon), 1st--4th October 2007]. / Compte rendu du cours international de la Fédération mondiale des Sociétés de Neurochirurgie et du congrés de la Société Camerounaise de Neurochirurgie Yaoundé (Cameroun), 1er--4 octobre 2007.

Neurosurgery remains a very marginal activity in sub-Saharan Africa. In this part of the world which counts nearly 40 countries, some do not have a single neurosurgeon, some have one to five, the number of ten neurosurgeons per country remaining an exception! In its concern of popularizing and of developing neurosurgery worldwide, the WFNS organized an international course in Africa, October 2007 2nd-3rd in Yaoundé (Cameroon). The Cameroon Neurosurgery Society (CNS) took this opportunity to organize its very first congress in the presence of the WFNS delegation from October 1st to 4th, 2007. The joint meeting with the WFNS was baptized the "African Week of Neurosurgery". This special event was a first in sub-Saharan Africa. The delegation of the WFNS, led by Professor J. Brotchi (Belgium) President of the WFNS, was made up of Professors A. Sousa (Brazil), Mr. Choux (France), N. Tribolet (Swiss), M. Arraez (Spain), A. Bricolo (Italy), A. Kamlichi (Morocco), G. Dechambenoit (France), K. Kalangu (Zimbabwe). Twenty three neurosurgeons coming from nine African countries (Cameroon, Nigeria, Gabon, Congo, Niger, Burkina Faso, Ivory Coast, Senegal, and Guinea) took an active part in work. The scientific success of this event led to the creation of the "Association of Neurological Surgeons of Africa (ANSA)" which will be the WFNS-Africa interface in order to insure the development of neurosurgery in Africa.
