The Cane rat (Thryonomysswinderianus) is an African rodent described in 1827 by Temminck. In order to make of it a model animal of laboratory, it is subjected to research in many domains for few years. Objective: The aim of this work was to describe the anatomy of the carotid Artery System of the cane rate.Materials and methods: It was about a prospective experimental study carried out on a series of eight adult sacrificed and put at death cane rats. After realizing a previous thoracic shutter, a vascular washing was performed by cardiac path followed by two injections of latex colored differently. The first one in red color and the second in blue are respectively carried out on the left and right heart. The Craniospinal blocks carrying the heart and the supra cardiac vessels were removed and immersed in a solution of formaldehyde at 10% during 72 hours. The anatomy of carotid artery was studied after dissection of the blocks. Results: With their origin, the two common arteries carotid were born by a common trunk at the convexity level of the aortic arch. They had an ascending way along the trachea and were divided then into two branches under the solid massif of the mandible: An external branch for the bodies of the face and an internal branch which moves towards the cerebral trunk. Conclusion: This study enables us to show that the two arteries common carotids are born by a joint base from the aortic arc and that the internal artery carotid does not take part in the constitution of the arterial circle of the base.

Purpose: The elbow bone traumas are very serious lesions that can compromise the function of this joint in the future. These lesions are most severe when there is a defect of bone which affects one component of the joint. Case report: We report a case of open trauma of the left elbow from a right-handed girl of 21 years, during an accident on the highway. On admission, the victim had a signifi cant defect of skin-muscle of the anterior medial aspect of the elbow. The exploration revealed a major loss of bone affecting the humeral trochlea which was completely absent. In emergency the patient has benefi ted from joint stabilization by an external fi xation, with a fi lling-in of the humeral-ulnar joint space with a cement spacer. The loss of muscle substance was fi lled with a latissimus dorsi fl ap followed by a skin graft made the days that followed. Conclusion: After a brief review of the literature, the authors emphasize on the need to preserve the joint space through the establishment of the spacer which is the only guarantee for maintaining the stability of the elbow, which also allows to consider arthroplasty surgery later.

Abstract:Osteomyelitis is one of the infectious diseases frequently encountered in developing countries. It is a chronical infection that concerns the long bones' diaphysis which treatment can be very laborious. We present two cases of chronic bilateral osteomyelitis of the femur observed on a 42 years lady and a 15 years teenager, both with sickle cell disease, AS the former and homozygote SS the latter. The symptomatology was dominated by persistent pains in both thighs with a bilateral purulent discharge fistulizing the skin. Radiographic assessments have helped to highlight bilateral images of pandiaphysitis bulky with intramedullary receivers in both cases. Surgical treatment consisted of a fistulectomy and a sequestrectomy after achieving a wide flap bilateral femoral diaphysis. Some pus samples were made and allowed to isolate in both cases a Staphylococcus Aureus. Clinical Bilateral forms are rarely found in literature. In all cases, the germ implicating it as well as the field are predictive factors in the occurrence of this rare clinical form Chronic Osteomyelitis, Bilateral, Femur Introduction:
