Cervical meningoceles are the least common forms of spina bifida, representing between 4% to 8% of all spinal dysraphisms. They are not accompanied by neurological deficit in childhood but attached cord syndrome can occur with growth. Surgical treatment, in addition to avoiding rupture and correcting the aesthetic damage, will preserve neurological functions. We report 2 cases that we took care of. They are a 5-month-old infant and a 3-year-old girl. The first presented a 7 cm rounded meningocele pedunculated through the C1 lamina defect. The second presented an 8.6 cm polylobed meningocele pedunculated through the C2 lamina defect. They both underwent surgery with good progress.

ng>Introduction:ng> Thoracic and lumbar spine fracture, type C of MAGERL is one of the most biomechanically and neurologically unstable lesions, induced by significant damage to the bone, disk and ligament complex. ng>Materials and Methods: ng>We report two cases of Thoracic and lumbar fracture, type C of MAGERL hospitalized in the neurosurgery department of the Grand Yoff General Hospital in Dakar during a period from June 2014 to June 2017. ng>Observations:ng> 1st case: 44-year-old patient, referred from abroad because of multi systemic trauma related on road traffic accident. On physical examination sustained a thoracic spine trauma classified ASIA D. Body CT scan showed T4 - T5 fracture-dislocation Type C of MAGERL, multiple ribs fracture with a right slight haemothorax, a sternal, a left humerus and scapulas fracture. Thoracic Posterior approach was done using laminar hooks. Clinical and anatomical results are good. 2nd case: 20-year-old patient, referred for thoraco-lumbar trauma because of occupational accident. The initial clinical examination classified it ASIA B. CT scan investigation, demonstrated a L1-L2 fracture type C of MARGEL. Thoraco lumbar spine posterior approach was done using pedicular screw fixation. Two years after trauma the patient recovered completely from his paraplegia. ng>Conclusion: ng>Thoracic and lumbar spine fractures, type C of MAGERL are compelling and instable fracture. Performing posterior instrumentation can achieve a good stabilization and reduction of the lesion.

Spinal Cord Injuries without Visible Bone Lesions: Analysis of Four Consecutive Cases

引用

Open Journal of Orthopedics 2018年第3期8卷 95-101页

作者： Magatte Gaye Sarah ntshindj Mutomb Amadou ndiasse Kasse n’famara sylla Sagar Diop Alvin nah Doe Aboubacar Sidiki Sangharé Mouhamadou Habib Sy Youssoupha Sakho Department of neurosurgery Grand-Yoff General Hospital Dakar Senegal Department of Orthopedics and Trauma Surgery Grand-Yoff General Hospital Dakar Senegal

Objectives: Interest of this study is to report four cases of spinal cord injuries without bone lesion. Evolution of the injured patients according to the initial clinic assessment at admission and the treatment performed are discussed. Materials and Methods: From January to December 2016, we performed a retrospective study at the neurosurgery Department of Hospital General Grand Yoff of Dakar. Four patients were followed for spinal cord injury without visible bone lesions. We analyzed the clinical, radiological, therapeutic and evolutionary data. Trauma caused by stabbing was excluded. Results: In a year, 83 cases of spinal trauma with neurological deficit were hospitalized in the department. Among them, 4 had spinal cord injuries without visible bone lesions. The average age was 31.7 years with extremes ranging from 14 to 47 years. The sex ratio of male/female was 3. We have recorded 2 cases of road traffic accidents, 1 case of fall from height and 1 case of sports accident. On the neurological level, we found 3 cases of tetraplegia, and 1 brachial monoplegia. Computed tomography in all patients was normal. All of them benefited from magnetic resonance imaging that showed spinal cord injury. All patients were under conservative treatment. One patient fully recovered, two partially and one passed away. Conclusion: In presence of any post traumatic myelopathy case, the absence of disco-vertebral lesions should bring to mind the SCIWORA as well as indicate the realization of magnetic resonance imaging.

Polycyclic Evolution of Paleoproterozoic Rocks in the Southwestern Part of the Mako Group(Eastern Senegal,West Africa)

International Journal of Geosciences 2014年第7期5卷 739-748页

作者： Papa Moussa ndiaye Edmond Dioh famara Diatta Alassane Traore Makhoudia Fall Ousmane Balde Département de Géologie Universite Cheikh Anta DiopDakarSénégal Institut Fondamental d’Afrique noire Universite Cheikh Anta DiopDakarSénégal Institut de Technologie nucléaire Appliquée Universite Cheikh Anta DiopDakarSénégal

After an extensional stage giving rise to tholeiitic basalts and gabbros, the south western part of Kédougou Kéniéba Inlier (KKI) was affected by three phases of compressionnal deformation. The first phase (D1) was related to nE-SW stress that led to northeastward thrusting. Early granitoids would be implemented during this tectonic event. The second phase (D2) was due to East-West compressional stress that created combined strike sleep faults: nnW-SSE and nnE-SSW respectively sinistral and dextral. During this phase, some volcanic rocks and gabbros were mylonitized, hydrothermalized and transformed into quartzites. These quartzites were considered as sedimentary rocks in previous studies. Granitic plutons and andesites took place during this tectonic phase. D3 deformation occurred towards the end of the Eburnean orogeny. It would be held in two episodes. In the first episode, WnW-ESE stresses created conjugate shears: sinistral nnW-SSE and dextral nE-SW. In the second episode, stresses moved toward the nE-SW direction and made the resulting brittle structures arranged in nS dextral corridors.
