Objective: Study the contribution of the DIVA 3D dissection table in the teaching of anatomy at the Faculty of Medicine and Odontology of Bamako. Material and Methods: This was a qualitative study carried out from November 1 to December 30, 2023 at the clinical and morphological anatomy laboratory of the Faculty of Medicine and Odontostomatology of Bamako. Included in this study were students who participated in practical and tutorial sessions. The variables studied during this study were: the previous performance of dissection on a cadaver by the students, the opinion of the students on dissection on a cadaver, the replacement of dissection on a cadaver by virtual dissection in the absence of a body, the level student satisfaction. Results: We surveyed 130 participants. The average age was 22 ± 0.2 years with extremes of 17 and 29 years. 95.3% of participants were students. According to 66.7% of participants, virtual dissection is a good palliative in the absence of a corpse. 95.3% of participants found using the virtual dissection table easy with an average of 7.88 ± 1.4. The overall assessment was well rated by 99.3% of participants. Conclusion: According to the results of this study, the virtual dissection table should be improved by integrating commented videos. The use of the DIVA 3D virtual dissection table during practical and tutorial sessions is well appreciated by the students. We believe that the teaching of anatomy using 3D digital technology should be included in the study programs of the Faculty of Medicine and Odontostomatology.

Olecranon Bone Tumor Complicated by Ulnar Nerve Paresis Revealing Tuberculous Osteitis—About a Case

引用

Surgical Science 2023年第3期14卷 192-196页

作者： Abdoul Kadri Moussa Mahamadou Diallo Kalifa Coulibaly Layes touré Mamadou Bassirou Traoré tata touré Adegné Togo Orthopedic-Traumatology Department CHU Gabriel tourE Bamako Mali Traumatology Orthopedic Department of The Hospital and University Center: CHU Kati Mali Department of Orthopedics-Traumatology Sikasso Regional Hospital Sikasso Mali General Surgery Department CHU Gabriel tourE Bamako Mali

Introduction: The localization of bone tuberculosis at the level of the olecranon is rare and can pose a problem of differential diagnosis with a tumoral affection. Only the biopsy allows the diagnosis of certainty. The goal was to report our first case to do a review of the literature. Clinical Observation: This was a 64-year-old patient who consulted 2 years after the onset of symptoms for swelling and mechanical pain in the left elbow. On clinical examination there was a firm consistent mass measuring 6/4 cm in diameter, not very painful and hot on the posterior surface of the left elbow, accompanied by paresthesias in the territory of the ulnar nerve associated with partial functional impotence of the left forearm with little altered general condition. The X-rays of the left elbow showed extensive bone lysis of the olecranon with fracture of the base of the olecranon. The CT Scan of the elbow performed showed osteolysis of the olecranon with extensive bone reactions at the distal end of the humerus. The biopsy carried out with histological examination concluded with an aspect of tuberculous osteitis and the culture came back sterile. A curettage was performed associated with anti-tuberculosis treatment for 12 months as well as the placement of a posterior splint. The evolution at 9 months was unsatisfactory with persistence of paresis and stiffness of the elbow. Conclusion: Tuberculous osteitis of the olecranon can simulate a malignant tumor with non-specific signs of bone tuberculosis. Only the anatomopathological examination is definitive for the diagnosis. The treatment is multidisciplinary. Orthopedic evolution is difficult to predict.

Objective: To carry out a 3D vector reconstruction of the muscles of the ventral region of the neck from anatomical sections of the “Korean Visible Human” for educational purposes. Materials and Methods: The anatomical subject was a 33-year-old Korean man who died of leukemia. He was 164 cm tall and weighed 55 kgs. The anatomical sections were made in 2010 after an MRI and a CT scan. A special saw (cryomacrotome) made it possible to make cuts 0.2 mm thick on the frozen body, i.e. 5960 cuts. Sections numbered 1500 to 2000 (or 500 cuts covering the neck) were used for our study. A segmentation by manual contouring of each anatomical element of the anterior neck region was done using Winsurf version 3.5 software on a laptop PC running Windows 7 equipped with an 8 gigabyte RAM.

Objectives: The purpose of this work was to determine the dimensions of CFA before the birth of the deep thigh artery, describe the mode of termination of the CFA, search for CFA collaterals, and describe the anatomical variations of the CFA. Methodology: This was a prospective study conducted at the Anatomy Laboratory of the Faculty of Medicine and Odonto-Stomatology of Bamako. CFA arteries of 12 fresh corpses of adults include 9 men and 3 women. A total of 24 CFA arteries were dissected and photographed. Results: The mean length of CFA was 50.9 ± 12.55 mm (range: 31 and 93 mm). Its average diameter was 9.12 ± 1.17 mm (range: 7 and 12 mm). In 70.83%, the CFA artery ended without any particularity. There was 29.17% anatomic variation in the CFA termination mode. The CFA divided into 3 branches (trifurcation) in 25%. The 3 branches were in 20.83%, the FS and a common core to LFCA and AQ;in 4.17%, they were the SFA, the DFA and the MFCA. In 4.17%, it divided into 4 branches which are: the SFA, the DFA, the MFCA and a common core to QA and LFCA. The CFA gave as collateral: circumflex superficial iliac artery in 22 cases (91.67%), superficial epigastric artery in 19 cases (79.17%), upper external pudendal artery in 20 cases (83.33%), and lower external pudendal artery in 14 cases (58.33%). We noted in our series 9 anatomical variations at the collateral level of the CFA or 37.5%. The CFA gave birth to the following branches: the MFCA in 4 cases or 16.67%, the LFCA in 1 case or 4.17%, the QA in 1 case or 4.17%, and a common core to the QA and LFCA in 3 cases or 12.5%. Conclusion: The length of CFA is important. The variations of CFA are frequent and important to know in clinical and surgical practice.

Forensic Medicine and Anatomy Research 2020年第2期8卷 11-17页

作者： Babou Ba Siaka Diakité Abdoulaye Kanté tata touré Moumouna Koné Nouhoum Ongoiba Abdel Karim Koumaré Siaka Sidibé Laboratoire d’Anatomie et de Morphologie Clinique FMOS BamakoMali Service de Radiologie CHU Point GBamakoMali Service de Chirurgie“B” CHU Point GBamakoMali

Roughly quadrangular, the chiasma presents many morphological variations. The optical chiasm, odd and symmetrical structure of the optical pathways, is a required passage of the axons of neurons for the visual pathways. Any modification of its morphology evokes a pathological process, generally tumoral. The quality of MRI images rivals that of anatomical slices. So the MRI is essential for the study of the chiasma. The aim of this work was to study the morphometry of the optic chiasm in patients addressed for cerebral MRI to the imaging department of the university hospital of the POINT-G, during the period from July 29, to November 30, 2016. All patients who had a normal examination of the optic chiasma, numbering 15, were included in this study. In 86.66% of cases the chiasma had a quadrilateral form. Its average length was 8.73 mm and its average width was 13 mm. The average thickness was 4.13 mm.

Aim: To perform a vector 3D reconstruction of the neck skeleton from the anatomical sections of the “Korean Visible Human” for educational purposes. Material and Methods: The anatomical subject was a 33-year-old Korean male who died of leukemia. It measured 164 cm and weighed 55 kgs. The anatomical cuts were made in 2010 after an MRI and a CT scan. A special saw (cryomacrotome) made it possible to make cuts on the frozen body of 0.2 mm thick or 5960 slices. Sections numbered 1500 to 2000 (500 neck sections) were used for this study. Manual contouring segmentation of each anatomical element of the anterior neck area was done using Winsurf software version 3.5 on a PC. Results: Our vector 3D neck model includes the following: cervical vertebrae, hyoid bone, sternum manubrium and clavicles. This vector model has been integrated into the virtual dissection table Diva3d, a new educational tool used by universities and medical schools to learn anatomy. This model was also put online on the Sketchfab website and printed in 3D using an ENDER 3 printer. Conclusion: This original work is a remarkable educational tool for the study of the skeleton of the neck and can also serve as a 3D atlas for simulation purposes for training therapeutic gestures.

Objectives: The purpose of this work was to measure the dimensions of the femoral veins, to describe the affluent and the variations of the femoral veins. Methodology: Twenty-four femoral veins of 12 fresh adult cadavers were dissected and photographed. Results: The diameter of the superficial, deep and common femoral veins was respectively 8.75 mm;7.60 mm and 13.95 mm. The common femoral vein was 80.70 mm long. At the level of the superficial vein, the modal disposition was noted in 79.17%;as anatomical variations, it was split in 2 cases, the presence of a collateral canal in 1 case and in 2, and it received a quadricipital muscle vein. At the level of the deep femoral vein, the modal disposition was noted in 16.67%, and the anatomical variations were noted in 83.33% where it received no affluent in the femoral trine. The modal disposition was noted in 91.67% at the level of the mode of birth of the common femoral vein, in 16.67% at the level of its tributaries. The anatomical variations were noted in 8.33% in the mode of birth of the femoral vein, in 83.33% in which the common femoral vein received, in addition to the large saphenous vein, other tributaries, the most frequent of which were the quadricipital veins and the circumflex femoral veins. Conclusion: The diameter of the femoral veins is important. The main tributaries of the common femoral vein are GVS, VQ and circumflex femoral veins. The femoral variations are numerous and important to know to avoid a possible misdiagnosis in case of their thrombosis.

Aim: The purpose of this work was to describe the left renal retro-aortic vein. Methodology: A case of left renal retro-aortic vein was discovered on a corpse of male, 45-year-old adult during the dissections to the laboratory of anatomy of the Faculty of Medicine of Bamako. The way at first was a xypho-pubic median and two side abdominal sections under costal and inguinal. The side sections under costal went of the median section to sides by following the costal edge. The inguinal side sections went of the median section to the anterior and superior iliac thorns. The abdominal wall was opened and reclined by every quoted. The small intestine and the colonist were resected with their meso. The renal pedicle was dissected on each side. The abdominal aorta and the inferior vena cava were dissected by the diaphragm up to the headland. Arteries and iliac veins were also dissected. Results: On male corpse, 45 years old, we discovered a left renal retro-aortic vein in horizontal route, and the trunk of the left renal vein was formed by the confluence of three veins at the level of the left renal hilum. The left renal vein passed almost horizontally below the left renal artery. It passed then behind the abdominal aorta to end in the inferior vena cava at the level of its left side face. The right renal vein had a normal aspect. Conclusion: The left renal retro-aortic vein is one of the variants of the anomalies of the system cellar inferior. The left renal retro-aortic vein could be responsible for renal aplasia.

The brachial plexus (BP), established by the lap twigs of the last four cervical nerves and the first thoracic nerve, assures the driving and sensory innervation of the thoracic member. We bring back a case of rare anatomical variation of the brachial plexus. It is a 34-year-old corpse dissected in the laboratory of anatomy of the Faculty of Medicine and Odontostomatology of Bamako in September 2017. The lap twig of the fourth cervical root (C4) participated in the constitution of the brachial plexus. The superior trunk was normally constituted. The average trunk was formed by the cervical roots C7 and C8 instead of only C7. And consequently the inferior trunk was constituted by the thoracic root T1. The posterior beam was only formed by the posterior branches of the superior and more average trunk. The medial beam was formed by all of the inferior trunk which did not give posterior branch for the formation of the posterior beam. The variations of the brachial plexus could entrain failures in the loco regional anesthesia of the brachial plexus.

Purpose: Our purpose was to describe the anatomy of the external branch of the upper laryngeal nerve and to estimate the frequency of nerves at risk during the total thyroidectomies sub. Methodology: We realized in the CHU Point G in Bamako a forward-looking study over a period going from September 1st, 2016 till December 31st, 2017. All the patients operated by thyroidectomies subtotals for mild goiters were included to whom a systematic location of the external branch of the superior laryngeal nerve in the space avascular of Reeve was realized. Cancers and other thyroid pathologies were not included. Results: We counted and operated 120 cases of mild goiters. The external branch of the superior laryngeal nerve was seen and dissected in 80.8%;it was not seen in 19.2%. According to the classification of Cernea: the type 2 was found in 80.8% of the cases with him under typical 2b in 47.5% and under type 2a in 40 (33.3%). The global frequency of lesion of the external branch of the upper laryngeal nerve was 10.8% at 9 patients among whom 6 who presented a BENLS of Type Ni. Conclusion: The external branch of the upper laryngeal nerve of type 2 presents a risk of wound because the surgeon treats the upper pedicle at the level of the critical centimeter place over the upper pole of the thyroid. The identification of the nerve during the thyroid surgery is the solution of choice.
