Introduction: Pseudarthrosis (PSA) of the diaphysis of long bones still remains a current problem, despite improvements in the treatment of these fractures. Our study aims to study the epidemiological and therapeutic aspects of PSA of the diaphysis of long bones. Method: This retrospective work concerns 30 cases of non-union of the diaphysis of long bones treated in the orthopedic and trauma surgery department at Donka National Hospital, during a period of 18 months from January 1, 2019 to June 30, 2020. Results: We recruited 30 patients, 80% of whom were male, with an average age of 39.9 years. Public road accidents (AVP) represented the main cause of fractures of the diaphysis of long bones 87%, they were open in 25 cases or 83%. The fractures were located in the middle 1/3 of the diaphysis of the long bones in 50% of cases. Treatment of initial fractures was traditional in 21 cases, orthopedic in 2 cases and surgical in 7 cases. It was aseptic nonunion in 28 cases (93%) and septic nonunion in 2 cases. They were hypertrophic in 7 cases, slightly hypertrophic in 5 cases, oligotrophic in 11 cases, atrophic in 6 cases and with bone defect in 1 case. The treatment was based on osteosynthesis including 16 cases of screwed “PV” plate: 7 cases of centromedullary “ECM” nailing, 2 cases of external fixator, 1 case of broaching and 4 cases of Plastering. The results according to ASAMI criteria on an anatomical level were excellent in 19 cases, good in 3 cases and poor in 3 cases, with a union rate of 76%. And 5 patients undergoing consolidation. Conclusion: Based on the literature data and the experience of our department, the true treatment of PSA requires correct management of the initial fracture without forgetting the interest in preventing AVP which appears to be an element essential, making it possible to reduce the incidence of fractures of the diaphysis.

Open Journal of Orthopedics 2024年第9期14卷 404-410页

作者： Tafsir Camara Amira Aboud Ibrahima Sory Bangoura Madjirabe Nassaradengar Hippolyte Mohamed Youla Urbain Judicael Adou Kouassi Bah Mohamed lamine léopold lamah Orthopedics-Traumatology Department of Ignace Deen University Hospital Conakry Guinea Orthopedics-Traumatology Department of Donka University Hospital Conakry Guinea

Introduction: Mechanical complications after osteosynthesis are spontaneous and harmful modifications of the joint compromising the consolidation process. The aim of this study is to report on the frequency of these complications and their management in the Orthopaedic-Traumatology Department of CHU Ignace Deen. Patients and Methods: we conducted a retrospective descriptive and analytical cross-sectional study from January 2017 to December 2022. It focused on the records of patients hospitalized and treated in the department for a mechanical complication after osteosynthesis. Results: The frequency of mechanical complications was 1.2%, with an average age of 44.2 years and a sex ratio of 3.2 in favor of men. Non-compliance with postoperative instructions, non-compliance with surgical technique, postoperative infection and early loading were the main contributing factors. Disassembly of the screw-plate was the most common cause in 6 cases (35.5%), with a mean delay of 4.1 months. Revision osteosynthesis was carried out using screw plates in 8 cases (47.1%). Conclusion: Mechanical complications of osteosynthesis are less frequent traumatic conditions in our department. Several factors contribute to their occurrence.

Open Journal of Orthopedics 2024年第7期14卷 287-294页

作者： Abdoulaye Camara Karinka Kéita Mamady Doukouré Abdoul Karim Baldé léopold lamah Fatoumata Camara Alpha Mamadou Felah Diallo Ibrahima Marie Camara Mamadou Madiou Diallo Mamadou Cellou Diallo Donka University Hospital Center Conakry Republic of Guinea Ignace Deen University Hospital Center Conakry Republic of Guinea

Introduction: Fractures of the distal end of the humerus are becoming increasingly frequent in young subjects because of the increase in road traffic accidents, and in elderly subjects because of osteoporosis related to aging populations. Materials and Methods: It was a prospective, monocentric study from January 2018 to December 2020 involving 14 patients who received and were treated surgically for distal humeral fractures and followed up. Results: We collected 14 patients, including 11 men (78.57%) and 3 women (21.43%), with a sex ratio of 3.7. The mean age was 36.41 years. The circumstances of onset were dominated by road traffic accidents, with 12 cases (85.71%). The dominant side was right-handed, with 11 cases (78.57%). Standard elbow radiography revealed 8 cases of type A fractures (57.14%), 4 cases of type B and 2 cases of type C fractures of the AO. We performed lecestre plate osteosynthesis in 12 patients and external fixator in 2 others, using the trans-olecranial and transtricipital approaches. Elbow stiffness was the most frequent complication, with 6 cases (42.86%). After six months’ follow-up, our results were excellent and good in 78.57% of cases (MEPS). Conclusion: Surgical treatment with posterior approaches enabled us to achieve restitution of the articular surfaces, solid restraint and early mobilization of the elbow with satisfactory functional results.

Objectives: To determine the epidemiological, therapeutic and evolutionary aspects. Methodology: This was a retrospective study, from January 1, 2016 to December 31, 2018, on the files of patients aged 16 and over, admitted for patella fractures, treated surgically and followed up in our service. Results: The study involved 17 patients including 15 men (88.24%) and 02 women (11.76%) with an average age of 36.65 years. Workers were the most represented (29.42%);AVP were the leading cause of these fractures (52.94%). The fractures were open in 70.58% of cases. Associated lesions were dominated by femur fractures in 29.42%. Duparc type II was the most encountered bone lesion with 47.06% of cases. All our patients benefited from regional anesthesia. Bracing was the most used surgical treatment in 58.83%;the anterior approach was performed in all our patients. Four (04) cases of knee stiffness, two (02) postoperative infections and skin necrosis complicated the short and medium term consequences. After a two-year follow-up, radiologically one case of pseudarthrosis and one case of patellofemoral osteoarthritis were noted. According to the Bosman score, we found 17.65% excellent, 47.06% good and 35.29% poor functional results. Conclusion: Patella fractures are relatively rare. Treatment is primarily surgical for transverse and/or displaced fractures;Bracing is the osteosynthesis technique of choice. However, knee stiffness, pseudarthrosis and patellofemoral osteoarthritis are not uncommon.

Journal of Cancer Therapy 2017年第12期8卷 1086-1094页

作者： Bangaly Traore leopold lamah Surgical Oncology Unit National Hospital of Donka Conakry University Hospital Conakry Guinea Department of Orthopedics and Traumatology National Hospital of Donka Conakry University Hospital Conakry Guinea

Aim: The main aim of this study was to evaluate outcomes after surgical treatment of skin cancer. Methods: This retrospective cohort study concerned 46 patients who presented 43 skin cancers lesions surgically treated at surgical oncology unit, Conakry University Hospital. There were 29 (61.7%) squamous cell carcinoma, 12 (25.5%) melanoma, 4 (8.5%) sarcomas and 1 (2.1%) porocarcinoma. Surgical indications and prognosis factors were analyzed. Results: Surgical treatment included simple excision in 2 cases (3.8%), wide excision in 38 cases (71.7%) and amputation/disarticulation in 13 cases (24.5%). Inguinal lymph node dissection was performed in 16 patients (34.3%). Postoperative complications were wound suppuration (5 cases), lower limb lymphedema (4 cases), seroma (2 cases) and skin flap necrosis (1 case). Surgical margins were free in 28 (60.9%) patients, infiltrated in 3 patients (6.5%) and unspecified in 15 patients (32.6%). The median follow-up after surgery was 29 months. During the follow-up, 13 patients (28.3%) had a relapse. The relapse was influenced by surgical margins (p = 0.012) and iterative resection (p = 0.04). Overall survival was 65.2%. Factors related to survival in univariate analysis were: iterative resection (p = 0.008), fungated tumor (p = 0.037), the status of surgical margins (p = 0.002) and the occurrence of relapse (p = 0.0000). In multivariate analysis, the status of surgical margins was the only independent prognostic factor. Conclusion: The prognosis after surgical treatment of cutaneous cancers depends on the resection margins.

引用

Open Journal of Soil Science 2023年第7期13卷 340-354页

作者： labilé Kolie Simon Pierre lamah Alama Camara Department of Civil Ingeenring University Gamal Abdel Nasser of Conakry Conakry Republic of Guinea Department of Hydrology University of N’Zerekore N’Zerekore Republic of Guinea Scientific Research Centre of Conakry-Rogbané (CERESCOR) Conakry Republic of Guinea

limbita 1 is a hilltop settlement in the rural town of khorira, the district of Dubreka. It is a land of the locality commonly called “limbita quarry”, and widely converted by bricks manufacturers of Dubreka district and those of conakry area. However, no information about the characteristics of this land’s soil is yet available. The soil’s characteristics are then determined through the series of tests (granulometry, Atterberg limits, modified proctor, CBR, shear, odometric compressibility). These tests are carried out with samples derived from the site of limbita within the area of limbita 1. This work shows very consistent results that made it possible to deduce the very swelling nature of the soil.

Introduction: Total hip prostheses are a reliable means of treating hip disorders. It is indicated when pain and reduced mobility of the hip become incompatible with the patient’s daily activities. In low-income countries, the risk factors for hip disease are numerous, but the means for its management, such as total hip prostheses, are not. The aim of this work was to determine the morbi-mortality of total hip prostheses in the short and medium term in our department and to review the literature. Patients and Method: This was a prospective and descriptive study over a period of 9 years. It involved 50 THPs performed on 45 patients. Patients who had received a THP and were followed up for at least two years were included. We excluded patients who were lost to follow-up. The Moore-type posterolateral minimally invasive approach was used. Complications were investigated from the immediate postoperative period and in the medium term. The final functional results were evaluated according to the Postel Merle d’Aubigné score. Results: We performed 50 THPs out of 750 procedures, i.e. , 6.6%. The indications were: primary coxarthrosis 60%, necrosis of the femoral head 26%, post-infectious balloon hip 4%, and pseudarthrosis of the femoral neck 10%. The average time to the consultation was 2.4 years with extremes of 1 and 5 years. According to the terrain, sickle cell disease represented 18%, tuberculosis 12%. Postoperative complications were lameness 12%, dislocation 6%, suppuration 6%, death 4%, peri-prosthetic fracture 8%, loosening 2%, peri-articular ossification 2%, and paralysis of the external popliteal nerve 2%. Conclusion: Whoever performs a THP is obliged to monitor the patient as long as he/she is alive. Complications are possible at any time and can negatively change the assigned goal and force the surgeon to be expensive and sometimes inconclusive secondary interventions.

Surgical Treatment by Pinning of Carpometacarpal Dislocation at the Donka University Hospital Center: A Propos of 12 Cases

引用

Open Journal of Orthopedics 2022年第11期12卷 442-449页

作者： Diallo Mamadou Moustapha lamah leopold Barry Alhassane Camara Nouhou Mangue Diallo Alpha Mamadou Fellah Department of Orthopedic Traumatological Surgery of the Donka National Hospital Conakry Guinea

Carpo-metacarpal dislocations are rare hand injuries. They are misdiagnosed due to their non-specific clinical signs. The authors report on their experience in the management of carpometacarpal dislocations in a specialized hand surgery center. Our study included patients received and treated in the department for a carpometacarpal dislocation. Dislocation fractures of Bennett and Rolando were excluded. The postoperative functional evaluation took place after 18 months by the DASH score. Twelve patients participated: one case of neuro-algodystrophy and one pin infection. The mean DASH functional outcome score was 1.10 at 18 months. Since carpometacarpal dislocations are rare and easily misdiagnosed, the surgeon should assume the possibility of them in patients with high-energy trauma, and imaging studies should be carefully evaluated. Pinning is an effective treatment option that provides good long-term functional results.
