Introduction: Total hip arthroplasty of complex morphology is a challenge for the orthopaedic surgeon. Careful analysis of the hip’s anatomy helps to unravel the difficulties and anticipate the procedures to be performed and the implants to be planned. The aim was to identify the types of hip that make first-line THR difficult, specify the technical procedures to be used on these sites, and assess the functional results of the series. Material and Methods: This was a retrospective study that concerned patients operated on for total hip arthroplasty between January 2015 and December 2022 at the medical center “La Grâce” in Bobo-Dioulasso, Burkina Faso. Patients with coxarthrosis (on hip dysplasia, acetabular protrusio, acetabular malunion or neurological hip) and those with ankylosis of the hip, osteonecrosis secondary to neglected dislocation of the hip or hemoglobinopathy were included. Results: A total of 31 total hip replacements were performed in 30 patients. The mean age of patients at the surgery time was 36.2 years with extremes of 17 and 61 years. The male-to-female sex ratio was 1. The main indications for THA were the dysplasic hip osteoarthritis (11 cases) and the neglected hip dislocations (7 cases). In situ femoral neck osteotomy before hip dislocation was performed in seven cases. The acetabulum reconstruction techniques varied from the structural iliac bone graft (n = 3) and cancellous bone graft (n = 4) to the Kerboull plate (n = 1). After 45 months of mean follow-up, all hips were evaluated. The mean PMA score increased from 7.1 [4 - 8] before the surgery to 13.2 [13 - 17]. Conclusion: The large spectrum of challenges in complex hip management requires effective preoperative planning. Preoperative planning minimizes complications and ensures a better outcome.

Objectives: Atlantoaxial dislocation remains a rare and serious condition with a high preoperative and postoperative morbidity and mortality. Its successful surgical management is still challenging and gratifying for neurosurgeons. Several technics have been described such as wiring, trans articular screwing, C1C2 screwing with plate and screw introduced by Goel et al., and modified by insertion of polyaxially screw and rod many years later by Harms. Unavailability and expensiveness of upper cervical spine instrumentation device led us to C1C2 Wiring resulting in a good outcome. Finally, a quadriplegic patient with a more comfortable financial condition had ordered devices from abroad and benefit for Goel and Harms screwing technique and improved dramatically from ASIA A to ASIA E. Material and methods: This is a retrospective study of patients managed in our department by a same neurosurgeon from January 2019 to April 2024. Results: We defined 6 men and 1 woman with an average age of 33 years. Unrestrained driver in a rollover motor vehicle accident was most common. Only one patient was neurologically intact on admission. Neurovegetative disorders were noticed in one patient. Dislocation was associated to a fracture of the dens in two patients. Three patients have been successfully operated with remarkable outcome, mostly from ASIA A to E. Conclusion: C1C2 dislocation is a serious condition and C1C2 Wiring represents an effective and cheaper technic. Therefore, this technic should deserve consideration above all in low incomes countries when screwing devices are not available. Seatbelt should be demanded for motor vehicle drivers and passengers.

Introduction: Binding retains an important place in Africa. Leaving a health facility to see a bonesetter is common there, but a source of complications. The purpose of this work was to analyze the results obtained by bonesetter after discharge against medical advice. Methodology: Analytical cross-sectional study over a period of one year, including all patients admitted for limb fracture, discharged against medical advice for treatment with a bonesetter. Results: Thirty-nine patients were selected. The average age was 36.9 years, and the sex ratio was 5.50. The fractures were open in 35.9%. At a mean follow-up of 19 months, the course was marked by pain in 34.4% and inequality in limb length in 62.5%. Thirteen fractures (40.6%) were consolidated with axis defect, and 11 were without axis defect (34.4%). There were eight non-union (25%), and eleven patients (34.4%) presented with stiffness in one or more joints. Seven patients had died. Discussion: The problem of discharge against medical advice is found in all hospitals but is particularly marked for fractures in our context. The absence of an X-ray and ignorance of the rules of asepsis lead to complications. Only the fractures of the two bones of the leg had progressed well (5/8 good results). The rate of vicious calluses (40.6%) and non-union (25%) is high. Conclusion: Although a few cases have progressed favorably, the results of pat

Background: Serious trauma is the main cause of death for people under 40 years old. According to the WHO, in 2002, nearly 1.2 million people died worldwide from road traffic injuries. The vast majority (90%) are from low and middle-income countries. The diagnostic performance, the quality of the treatments offered, and the optimization of trauma care channels, make it possible to improve the management of serious trauma. This is not always the case in our context of a country with limited resources. Objectives: The objective is o describe the epidemiological, diagnostic and therapeutic aspects of premortal death in patients with traumatic injuries. Methods: This was a descriptive study with retrospective collection in the trauma emergency department of Yalgado Ouedraogo Teaching Hospital (Ouagadougou, Burkina Faso). All patients who died on the ward while in the hospital or on arrival were included. Results: 192 deaths were listed. The annual mortality was 1.6%, the sex ratio was 6.1 and the average age was 36 years. Road traffic accidents were the main etiology: 163 deaths (85%). Head injuries were the most common injuries: 45.3% of deceased patients had a Glasgow score ≤ 8. There w

Matrix Riccati Equations in Optimal Control

引用

Applied Mathematics 2024年第3期15卷 199-213页

作者： malick Ndiaye School of Computer Sciences and Mathematics Marist College Poughkeepsie USA

In this paper, the matrix Riccati equation is considered. There is no general way for solving the matrix Riccati equation despite the many fields to which it applies. While scalar Riccati equation has been studied thoroughly, matrix Riccati equation of which scalar Riccati equations is a particular case, is much less investigated. This article proposes a change of variable that allows to find explicit solution of the Matrix Riccati equation. We then apply this solution to Optimal Control.

The authors reported a case of trauma with uterus rupture at 35 weeks gestation with fetal death in uterus with a trauma of the right limb injuries during a serious road accident. Aim: the aim is to show the increasing of road accident with the motorized tricycle and their many risks for pregnant woman. Case Presentation: our patient was thrown from the back cargo of a motorized tricycle (three-wheeled vehicle) after a collision with a truck in a rural area from 150 km to Bobo-Dioulasso. She sustained a closed abdominal injury and a severe right lower limb open injury. At admission in our department in the Teaching Hospital, she was conscious, shocked with hemodynamic instability, including low blood pressure (75/52 mmHg), rapid heart rate (140 pulses per minute), rapid breath rate (40 per minute), and cold extremities. Abdominal examination was painful with uterine hypertonia, 28 cm height uterus, and no fetal heart heartbeat. A laparotomy in urgency revealed a rupture of the uterus fundus with a dead fetus. A conservative surgical treatment was performed. An open trauma to the right limb was managed by the orthopedists with a good outcome. Conclusion: Accident trauma during pregnancy is becoming more and more frequent with the increase in means of transport in urban and inter urban areas. The transport way

Nasopharyngeal liposarcoma is an extremely rare clinical entity. Less than ten cases have been reported in the literature. It mainly occurs in humans. The non-specificity of the clinical and radiological signs explains the difficulty of the diagnosis confirmed by anatomopathological and immunohistochemical examinations. Its pathogenesis remains obscure and often correlates with genetic abnormalities. Pleomorphic liposarcoma is its rarest subtype, remarkable for its aggressiveness and rapidity of growth. Complete surgical excision remains the treatment of choice. We report a case of liposarcoma whose diagnosis was made during histological examination coupled with immunohistochemistry. .

Purpose: Traumatic hip dislocations (THD) are rarely reported from developing countries. The aim of the current study is to describe the trauma, the presentation, the treatment and the outcome patterns of THD received in the trauma unit of an emergency department (ED) in west Africa. Patients and Methods: A retrospective ongoing study from 2008 to 2014 was performed at the ED. All patients over 15 years with an unreduced THD and an anteroposterior pelvic radiograph were studied. Data were collected and analyzed by means of a statistical software. Results: A total of 50 THD were included in the study. We found an average of seven dislocations per year with a mean age of 36 years mainly males (n = 37). Road traffic accidents by motorcycle (n = 20) were the common circumstance of trauma. Forty-five extra-pelvic THD were diagnosed. According to the Bigelow classification, THD were classified posterior (n = 33), anterior (n = 10) and irregular (n = 2). Associated acetabular fractures (n = 36), ipsilateral lower limb fractures (n = 10) and sciatic nerve palsy (n = 2) were also found. The THD cases were treated by closed reduction (n = 34), open reduction (n = 6) and Girdlestone procedure (n = 1). The outcome after 16 months showed 21 good and excellent functional results and one death. The short term complications were post traumatic arthritis (n = 10) and osteonecrosis (n = 2). Conclusion: The THD occurrences are important in our emergency department. They are characterized by the place of motorcycle accidents and by the delayed reduction due to hospital’s locations and numbers and beliefs. A reduction before four hours, an earlier rehabilitation, a non-use of traction and a short hospitalization time below 14 days gave better results.

Introduction: Floating bone injury or bipolar dislocation is a concurrent dislocation at both ends of a long bone or a flat bone. It is an exceptional injury. We report 11 consecutives cases of floating bones. Objectives: The aim of the study is to analyze the frequency, the mechanism of injury and clinical forms of floating bones, and to present the results of their management. Material and Methods: A ten years ongoing retrospective study was held in four trauma departments. Eleven cases of floating bones were identified. The floating bones characteristics such as the injured bone, the patient age and sex, the mechanism of injury, the dislocations directions, the associated complications, the treatment and the outcome were studied. Results: Nine male and two female patients, with a mean age of 37 years [19 - 65 years range] presented a concurrent bipolar dislocation of one bone or a group of bones. They sustained a road traffic accident (n = 5), a workplace accident (n = 3), a fall from height (n = 2), and a sport accident (n = 1). The clavicle (n = 3) and the first metatarsal (n = 3) were the most frequently involved. The others floating bones were the radius-ulna complex (n = 1), the radius-lunatum complex (n = 1), the first metacarpal (n = 1), the first phalanx (n = 1) and the femur (n = 1). The floating bones ends displacement occurred in the sagittal plane (the forearm, the femur, the first phalanx and the first metatarsal) and in the horizontal plane (the clavicle, the first metatarsal and the first metacarpal). We defined direction displacements as bidirectional asymmetric (n = 10) or unidirectional symmetric (n = 1). Associated complications were fractures (wrist, hip, tarso-metatarsal joints) and wounds (fingers, metatarso-phalangeal joint). Dislocations were treated conservatively (n = 5) and surgically (n = 17) with excellent results (n = 13/16 joints). Three patients were lost of view. Conclusion: Our study described the characteristics of this exceptio
