Fracture of the Humeral Palette in Adult Patient: Therapeutic and Evolutive Aspect at Gabriel Touré Hospital: About 35 Cases

Introduction: Fractures of the humeral pallet occur between the distal insertion of the anterior brachial muscle and the joint space of the elbow. It represents 2% of all elbow fractures. These lower humeral fractures present a therapeutic challenge to trauma. These fractures are in the majority of joint cases and can be accompanied by loss of substance, which makes their functional prognosis random despite the application of the main therapeutic principles: exact reduction with possible bone graft;stable osteosynthesis, usually allowing early rehabilitation. This work focused on identifying therapeutic aspects and assessing treatment outcomes. Material and Methods: This was a descriptive cross-sectional study of patients with a fracture of the humeral palette from January 2015 to December 2019 at the Orthopaedic Trauma Department CHU Gabriel Touré Bamako. Results: We collected 35 cases of fractures of the humeral palette. The average age was 39.25 years with extremes of 22 and 74 years. The male gender predominated (71.4%) with a sex ratio of 2.5. Etiologies were dominated by falls with 19 cases (54.3%) and stroke with 13 cases (37.1%). The standard X-ray of the face and profile of the elbow was performed in all our patients. The most frequent types of anatomoradiology were supra condylar fractures type A in 16 cases (45.7%), supra and inter condylar fractures type C in 15 cases (42.9%);4 cases of uni condylar fractures type B (11.4%). Associated lesions were observed in 42.85%. Surgical treatment was performed in 80% of cases. Complications were dominated by elbow stiffness in 18 cases (51.42%), secondary displacement in 5 cases (14.28%), ossifications in 4 cases (11.42%). At an average decrease of 3.2 years our results were considered good in 45.7%. Conclusion: Fractures of the humeral palette are relatively common with associated lesions. The complexity of the fracture with associated lesions makes treatment difficult with unpredictable evolution.

Small Cell Lymphoma of the Gastrocnemius Muscle: A Case Report

Introduction: The primary localization of non-Hodgkin lymphoma of the muscle is rare. Only the biopsy allows the certainty diagnosis. The aim was to report a first case of small cell lymphoma of the gastrocnemius in Mali and to do a review of the literature. Clinical Observation: It was about a 34-year-old woman who consulted 3 months after the onset of symptoms for swelling and pain in the left calf. On clinical examination there was a hard, painful and warm mass in the left calf, with paresthesias in the tibial nerve territory associated with partial functional impotence of the leg. The ultrasound revealed a hyper echogenic and heterogeneous non-vascularized mass of the left gastrocnemius muscle measuring 65 × 45 × 40 mm non-vascularized on color Doppler and pulsed in favor of myositis. Magnetic resonance imaging (MRI) concluded in a well-limited heterogeneous cystic mass in the left gastrocnemius muscle respecting the bone of benign appearance: remodeled Baker’s cyst? Considering the radioclinical unconformity, thoraco-abdominal CT was performed and revealed pulmonary metastasis. The biopsy carried out concluded with a small cell lymphoma of the gastrocnemial muscle. Marginal resection was performed associated with adjuvant chemotherapy. The advancement at 9 months was satisfactory.

Double Arthrodesis, Postero-Medial Release and Posterior Tibial Transfer in One Step in Paralytic Inveterate Equine Varus Foot

Introduction: Varus equine foot deformity is common in developing countries. The management of these deformities is surgical in adults. Several surgical techniques have been described with more or less satisfactory results. To our knowledge, no study has been performed on the simultaneous association of double arthrodesis, posteromedial release, and posterior tibial transfer in a single operation in inveterate paralytic varus equines feet. The purpose of this work was to evaluate the results obtained. Patients and Method: This was a retrospective descriptive study from January 01, 2018 to December 31, 2021. It concerned inveterate paralytic varus equines feet operated on by the simultaneous association in a single operative time of double arthrodesis of the foot, posteromedial release of the back foot and transfer of the posterior tibial muscle to the lateral cuneiform. We identified seven patients with a mean age of 22.1 years with extremes of 11 years and 36 years. There were three males and four females. The cause of the deformity was neurological in all cases. All patients had painful walking discomfort and shoeing difficulties. The average time to management was 13.3 years with extremes of 4 and 25 years. The chronology of the interventional steps was posteromedial release, arthrodesis, and transfer of the posterior tibial muscle to the lateral cuneiform. The average postoperative follow-up was 21.7 months with extremes of 6 and 48 months. The parameters studied were the duration of the procedure, complications related to the procedure, muscle strength at the last recoil, consolidation of the arthrodesis, residual pain, patient activity, gait perimeter, stepping, ankle mobility, residual deformity, footwear, protrusion of the transferred tendon, and the possibility of walking on the heel. Final results were graded according to the Angus and Cowell criteria. Results: No intraoperative complications were noted. An early superficial infection of the surgical site was noted. It was treated with local care and healed without sequel. Residual pain was present in one case. Tibiotalar osteoarthritis was observed in one case, which required a tibiotalar arthrodesis. At the last follow-up, consolidation of the arthrodesis was effective in all patients. The posterior tibial muscle was side 5 (n = 4) and 4 (n = 3). The patients’ activity was normal without assistance in all cases. The walking perimeter was greater than 1 km in six patients. Patient activity was normal without assistance in all cases. Stepping was absent in all patients. No difficulty with footwear was noted. According to the Angus and Cowell criteria, the result was good (n = 6), i.e. 85.7% and bad (n = 1), i.e. 14.3% of cases. Conclusion: This study suggests that double arthrodesis associated with posteromedial release and transfer of the posterior tibial in one step in inveterate paralytic varus equines feet, gives satisfactory results. It allows for easy shoeing and plantigrade walking without stepping. Complications are essentially represented by the absence of fusion of the arthrodesis and tibiotalar arthrosis.

Surgical Management of Recent Traumatic Epiphyseal Fractures-Detachments of the Distal Femur at Gabriel TouréUniversity Hospital

Traumatic epiphyseal detachment fractures of the distal end of the femur are a rare lesion whose severity is linked to disabling sequelae such as limb length inequality or most often axial deviation. In this report, surgical treatment aims to reconstruct the anatomy of the distal femur, to avoid secondary displacements and to allow early mobilization of the knee. Surgery carried out mainly by the technique of plugging in or screwing, opened or better still closed, can be a source of complications including migration of pins, infections, knee stiffness, and growth disorders. The aim of this work was to describe their epidemiological, anatomo-clinical, therapeutic and evolutionary aspects in the Department of Orthopedics-Traumatology at the CHU Gabriel TOURE. It was a retrospective study over 30 months from July 2019 to December 2021. In fact, it concerned 42 patients with traumatic epiphyseal detachment of the distal femur occurring within 21 days or less, on a healthy knee with cartilage fertile treated surgically and followed in the department. However, the diagnosis of traumatic epiphyseal detachment of the distal femur was retained thanks to the clinical examination and supplemented by radiographic images of the knee from the front and from the side. The treatment was surgical. The functional results were evaluated according to the functional criteria of the Eastern Orthopedic Traumatology Society (SOTEST). Forty-two patients included 32 boys and 10 girls of average age of 12 years with extremes of 8 years and 16 years. The lesions were classified according to the Salter Harris classification. We noted 24% type I (n = 10), type II 71% (n = 30), type III 2% (n = 1), type IV 2% (n = 1). Union was achieved in all patients within an average of 6 weeks with extremes of 4 and 12 weeks. The functional result was considered good in 20% of cases and very good in 80%. Traumatic epiphyseal detachment fractures of the distal end of the femur are a rare lesion whose severity is linked to disabling sequelae such as limb length inequality or most often axial deviation. Surgical treatment aims to reconstruct the anatomy of the distal femur, to avoid secondary displacements and to allow early mobilization of the knee.

A Review on Conductive and Transparent Materials Used in the Design of Transparent Antennas

In this review, we highlight the essential parameters of some transparent materials for use in the design of transparent antennas. ITO films with a sheet resistance of Rs = 10 Ω/sq and a T = 90% transmittance, we turn to materials that can be serious alternatives for ITO, such as graphene T = 97% for Rs = 60 Ω/sq and the micro-mesh metal. Wire mesh seems to be the best alternative T = 93% for Rs Rs = 0.022 Ω/sq at T = 81%, this is the micrometric pitch mesh.

Surgical Management of Unstable Superior Femoral Epiphysiolysis with Great Displacement

Introduction: Superior femoral epiphysiolysis (SFE) is a most progressive but sometimes abrupt displacement of the femoral head relative to the superior femoral metaphysis through the cervicocerebral growth plate of the femur. The displacement of the femoral head is most often downward and backward. It is a typical pathology of the pubescent adolescent, most often overweight. It occurs on average at the age of 12 years in girls and 14 years in boys. Unstable forms with large displacements have a high risk of femoral head necrosis and chondrolysis. Although in situ fixation is the generally accepted treatment for minor SFE, the treatment of more severe cases remains controversial. When the extent of the displacement makes it impossible to pass a screw between the femoral neck and the femoral head, the only option is to reduce the displacement. This reduction must be gentle, progressive and limited to the minimum necessary for osteosynthesis. Objective: The aim of the work was to evaluate the results of the technique of progressive reduction of epiphyseal displacement by transtibial traction followed by percutaneous fixation of the femoral head by screw. Patients and Method: This was a retrospective descriptive study over a 10-years period from January 1, 2013 to December 31, 2022. It focused on the surgical treatment of unstable upper femoral epiphysiolysis with large displacement in the orthopaedic trauma department of the University Hospital of Kati. All patients operated on in our department for large displacement SFE were included in this study. Cases of secondary large displacement upper femoral epiphysiolysis and patients who had already undergone surgery on the proximal femur were excluded. Continuous progressive traction on the Boppe splint through a pin under the anterior tibial tuberosity was performed for 15 days in all patients. The hip was flexed to 45° and the knee to 35°. Fixation was performed with one or two screws. No contralateral preventive fixation was performed. Minimum follow-up was one year. Functional outcome was assessed by the Postel Merle d’Aubigné score. Anatomical outcome was assessed by the quality of reduction, the occurrence or non-occurrence of femoral head necrosis, and chondrolysis. Results: We identified nine patients with a mean age of 12.8 years and extremes of 9 and 17 years. There were three boys and six girls. Trauma was mentioned in four cases. The cause was idiopathic in five cases. Functional impotence was complete in all patients. The slippage was acute on a chronic background in all patients. The left side was affected in 7 cases and the right side in 2 cases. The patients were overweight in 7 cases. The patient’s weight was within the normal range in two cases. At final follow-up, all nine patients were asymptomatic. Anatomically, all nine patients had a femoral head free of avascular necrosis. In eight patients, the posterior tilt was absent, identical to that obtained after the traction period. Only one patient had a moderate posterior tilt with a neck uncovering of less than 25%. Functionally, the PMA score was very good in eight cases and good in one case. Conclusion: This study shows that the treatment of acute and unstable forms of upper femoral epiphysiolysis by progressive reduction with transtibial traction can lead to satisfactory results. Reduction in large displacement forms should be gentle, progressive and limited to the minimum necessary for osteosynthesis. Magnetic resonance imaging examination is an essential and indispensable prognostic element. Indications for preventive fixation should be selectively reserved for specific cases.

Blount Method in the Management of Supracondylar Fractures of the Humerus in Children

Supracondylar fractures of the humerus are the most common traumatic elbow injury in children. Several techniques are described in their support. Blount’s method is one of the widely used orthopedic means. The objective of our study was to evaluate the results of supracondylar fractures of the humerus treated by this method in our department. This was a descriptive, longitudinal study with the prospective collection over a period of 12 months from May 2018 to April 2019. It focused on children aged 0 to 15 years treated in the Orthopedic Traumatology Department of the CHU of Kati for a supracondylar fracture of the humerus in extension. A minimum follow-up period of 6 months was necessary for inclusion. 12 patients were collected. The sociodemographic, anatomopathologic, therapeutic and evolutionary aspects were studied. The results were evaluated according to Flynn’s criteria. The male sex was predominant with a ratio of 2. The average age was 5.5 years. The average admission time was 12.5 hours. Domestic accidents were the main etiology (66.66%) and Type II fracture was the most frequent with 58.33%. The duration of immobilization was 42 days for 11 patients. Complications were 1 case of secondary displacement and 1 case of 12&#730 flexion deficit. The average Baumann angle was 72&#730. The result was satisfactory for all our patients. Supracondylar fractures of the humerus are common in children, especially boys. The method of Blount when it is well carried out by respecting the indications gives good results.

Treatment of Pelvic Limb Fractures in a Hospital of 2e Reference in Mali

Introduction: A fracture is a solution in the continuity of a bone. Pelvic limb fractures may involve one or more of the bones. They constitute a real public health problem, which requires the identification of the factors inherent to this phenomenon for better prevention, but also for quality management of fractures and sequelae. Objectives: Were to describe the epidemiological, clinical and therapeutic profile of pelvic limb fractures in Timbuktu Hospital. Patients and Method: We conducted a prospective, descriptive study in the Surgery Department of Timbuktu Hospital, covering a period of one year from January 1 to December 31, 2017. We collected 39 patients who presented with fractures of the pelvic limbs, who were hospitalized and monitored throughout our study. Results: We obtained a hospital frequency of 2.86% limb fractures. Among the 39 patients included in our study, the male sex was predominant in 69.2% of cases, the average age of our patients was 20.5 years. Pupils and students were in the majority in 48.7% of cases. Road traffic accidents were the most common cause of fracture with 59.0% of cases. The tibia was the most affected segment in 38.5% of cases. Surgical treatment was predominant in 64.0% of cases. We obtained very good results in 94.87% of cases. Conclusion: Limb fractures remain frequent due to road traffic accidents. Osteosynthesis treatment provides a good result with fewer complications.

Surgical Treatment of Recent Traumatic Epiphyseal Detachments of the Distal Femur in the Orthopedic and Traumatological Surgery Department of the CHU Bocar Sidy Sall de Kati: About 20 Cases

Introduction: To our knowledge, no scientific study has been conducted at the university hospital of Kati on recent traumatic epiphyseal detachment fractures of the distal femur. However, every day, children present in consultation for knee trauma. Conjugal plate fractures are by definition single to children. Any break in any solution of continuity of this plate is called an epiphyseal fracture or detachment. Objectives: To evaluate the results of surgical treatment of traumatic epiphyseal in detachments of the distal femur recent in children and adolescents. Patients and Method: This was a 13-month prospectively collected longitudinal descriptive study from September 1, 2016 to September 30, 2017. We identified and reviewed 20 medical records of recent traumatic epiphyseal detachments of the distal femur. The parameters studied were sociodemographic, lesion, surgical technique and evolutionary. Results: During the study period, the most affected group age was 12 to 17 years (85%) with an average of 14.65 ± 1.61 years (6 and 20 years). The victims were male (95%). The most frequent etiology was road traffic accident (95%), with a mean time to care of 26.42 ± 10.21 hours and Type II was frequently encountered (85%) with 35% of immediate complications. Cross-bracketing was the most commonly used surgical technique (85%). The result was good (65%). Conclusion: This study allowed us to observe a significant hospital incidence of epiphyseal detachment fractures of the distal femur. Cross pinning was the most commonly used surgical technique with fewer complications (35%) and a satisfactory result in 90% of cases.

Management of Subtalar Fractures-Dislocations at Ségou Hospital in Mali: A 7 Cases Series

Introduction: Subtalar or peritalian dislocation is rare;it represents 15% of peritalian injuries. The aim of this study was to describe the radioclinical and therapeutic characteristics and to assess the functional result. Patients and Methods: This study is about a continuous descriptive and prospective study over a period of 5 years. It has been conducted from March 2013 to February 2018 at the Ségou Hospital, a second referral hospital in Mali. The functional results were evaluated by the score of the American Orthopedic Foot and Ankle Society (AOFAS). Results: Seven cases of subtalar dislocation fractures were diagnosed in six male patients with an average age of 38 years (36 to 47 years old). In five cases the etiology of the trauma was a motorcycle accident and a fall from height. The lesion was bilateral in one case. The average time to care was 3 hours (1 to 9 hours). There was one case of open dislocation fracture with talus enucleation. The dislocation was medial in 6 cases and lateral in one case. It was pure in three cases. The treatment was orthopedic in 2 cases and surgical in 5 cases. The post-operative complications were complicated by an infection of the operative site in one case. The average length of hospital stay was 4 days. The functional result was excellent in 2 cases;good in 2 cases, fair in 2 cases and poor for 1 case. Conclusion: Subtalar dislocation is a rare and serious lesion of the posterior tarsus. The long-term prognosis depends on the earliness of treatment and the severity of the associated injuries.
