The aim of the study: was to improve the results of treatment in children with recurrent severe patellar dislocation, through the development of a differentiated approach to preoperative planning. Material and Methods. In SLLP Clinics Samara state medical University from 2014 to 2018 was observed 54 patients with this disease. In 37 patients recurrent severe dislocation. The average age of patients is 14.2 years. The patients underwent postural radiography of the lower extremities, radiography of the knee joint in the lateral projection, computed tomography of the knee joints, computed tomography of the hip joints. Research patients measured parameters, confirming mnohopocetny dysplastic changes of the joint angle Q, the index Insall-Salvati, the congruence angle on Merchant and anticarsia of the femoral head. Because of the severe degree of the disease, bone plastic surgery is indicated. Patients underwent corrective supracondylar derotation-dialysisa osteotomy of the femur in combination with medialization and distalization of the tibial tuberosity. During this operation, it is possible to perform a correction in all three planes. Results. In the postoperative period, 32 patients have no complications, 1 patient has relapse, 4 patients have contracture. In the long-term postoperative period 86.5% of positive results and 13.5% of unsatisfactory results, which is much lower than 36.1% - the percentage of complications according to the medical literature. Conclusion. The proposed personalized approach in preoperative planning for recurrent dislocation of the patella of severe degree, allows you to choose the best option for surgery.

Objective:to assess whether computed tomography (CT) data can  be used for metal transitional spine fixation in patients with thoracic  and thoracolumbar scoliosis at the stage of surgical intervention planning.Material and methods.Thirty-nine patients with grades 3 and 4  (according to V.D. Chaklin) or type I–III (according to the  classification proposed by L. Lenke) thoracic and thoracolumbar idiopathic scoliosis were examined. All the patients  underwent a comprehensive radiographic and CT examinations. The  radiomorphometric features of the spine were used to plan surgical interventions.Results.The protocol was clarified for preoperative scoliosis examination using CT data on cervicothoracic and  thoracolumbar vertebrae. A personalized approach to planning an  operation on the basis of CT examination permits one to eliminate  destabilization of the supporting elements of the corrective system  at the most. Reducing the risk of postoperative losses of correction  contributes to the use of multi-rod constructs.Conclusion.CT that enables a comprehensive assessment of existing pathology and clarification of the nature of impending surgery should be carried out in patients with thoracic  and thoracolumbar idiopathic scoliosis at the stage of preoperative  planning for metal transitional spine fixation.

Background: Calcium-suppressed (CaSupp) technique involving spectral-based images has been used to observe bone marrow edema by removing calcium components from the image. Objective: This study aimed to evaluate the knee articular cartilage using the CaSupp technique in dual-layer detector computed tomography (DLCT). Methods: Twenty-eight healthy participants and two patients with osteoarthritis were enrolled, who underwent DLCT and magnetic resonance imaging (MRI) examination. CaSupp images were reconstructed from spectral-based images using a calcium suppression algorithm and were overlaid conventional CT images for visual evaluation. The morphology of the knee cartilage was evaluated, and the thickness of the articular cartilage was measured on sagittal proton density– weighted and CaSupp images in the patellofemoral compartment. Results: No abnormal signal or density, cartilage defect, and subjacent bone ulceration were observed in the lateral and medial femorotibial compartments and the patellofemoral compartment on MRI images and CaSupp images for the 48 normal knee joints. CaSupp images could clearly identify cartilage thinning, defect, subjacent bone marrow edema, and edema of the infrapatellar fat pad in the same way as MRI images in the three knee joints with osteoarthritis. A significant difference was found in the mean thickness of the patellar cartilage between MRI images and CaSupp images, while the femoral cartilage presented no significant difference in thickness between MRI images and CaSupp images over all 48 knee joints. Conclusion: The present study demonstrated that CaSupp images could effectively be used to perform the visual and quantitative assessment of knee cartilage.

Objectives:to evaluate the effectiveness and satisfaction of pain management in patients with rheumatic diseases (RD) according to a survey in the COMPAS (Quality of Pain Management according to Patients with Arthritis and Back pain) study.Methods:the survey involved 1040 patients with RD (rheumatoid arthritis-40.6%, osteoarthritis -32.1%, spondyloarthritis-10.6%, connective tissue diseases-8.6% of patients). 76.8% were women, the mean age was 55.8±14.0 years. 35.7% of patients continued to work in their specialty, 31.6% had various degrees of disability. The effectiveness of pain therapy was evaluated by the patient in the last month preceding the survey on a 5-point scale, where 1 - no effect and 5-excellent effect. Patients ‘ satisfaction with treatment, possible reasons for the lack of effectiveness of pain therapy and the use of additional treatment tools were also evaluated.Results:as therapy for the underlying disease, 40% of patients received conventional disease modifying antirheumatic drugs, 33.1% - glucocorticoids, 7.2% - biological agents and 15.2% - symptomatic slow-acting drugs in osteoarthritis. At the same time, 68% of patients needed additional analgesic therapy with nonsteroidal anti-inflammatory drugs (NSAIDs). Slightly less than half of the surveyed patients (46.9%) noted a moderate effect of analgesic therapy, 22.7% - a low effect and 5% - no effect, 23.7% rated the effectiveness of therapy as good and only 1.7% - as excellent. At the same time, only 15.6% of patients were completely satisfied with the result of NSAIDs, 64% were partially satisfied with the treatment and 20.4% were completely dissatisfied. As the reason of insufficient effectiveness of NSAIDs, most often (34.3%) patients named fear of adverse events associated with taking drugs, 19.4% - weak drugs, 15.3% - insufficient attention of doctors to complaints, 6.6% - poor diagnosis of the causes of pain. Others found it difficult to answer or were completely satisfied with the treatment. 40% of patients used additional methods, most often chiropractic (12.3%), acupuncture (4.8%), physiotherapy (12.7%) and folk remedies (7.4%).Conclusion:A significant proportion of patients with RD don’t have adequate pain control. Only 25.4% of patients rate the result of treatment as good and excellent, and even fewer patients (15.6%) are completely satisfied with the results of therapy. Thus, a personalized approach to analgesic therapy is necessary, taking into account the expectations of patients regarding the results of treatment.Disclosure of Interests:None declared

Abstract Aims Increased complexity in cardiac surgery over the last decades necessitates more precise preoperative planning to minimize operating time, to limit the risk of complications during surgery and to aim for the best possible patient outcome. Novel, more realistic, and more immersive techniques, such as three-dimensional (3D) virtual reality (VR) could potentially contribute to the preoperative planning phase. This study shows our initial experience on the implementation of immersive VR technology as a complementary research-based imaging tool for preoperative planning in cardiothoracic surgery. In addition, essentials to set up and implement a VR platform are described. Methods Six patients who underwent cardiac surgery at the Erasmus Medical Center, Rotterdam, The Netherlands, between March 2020 and August 2020, were included, based on request by the surgeon and availability of computed tomography images. After 3D VR rendering and 3D segmentation of specific structures, the reconstruction was analysed via a head mount display. All participating surgeons (n = 5) filled out a questionnaire to evaluate the use of VR as preoperative planning tool for surgery. Conclusion Our study demonstrates that immersive 3D VR visualization of anatomy might be beneficial as a supplementary preoperative planning tool for cardiothoracic surgery, and further research on this topic may be considered to implement this innovative tool in daily clinical practice. Lay summary Over the past decades, surgery on the heart and vessels is becoming more and more complex, necessitating more precise and accurate preoperative planning. Nowadays, operative planning is feasible on flat, two-dimensional computer screens, however, requiring a lot of spatial and three-dimensional (3D) thinking of the surgeon. Since immersive 3D virtual reality (VR) is an upcoming imaging technique with promising results in other fields of surgery, we aimed in this study to explore the additional value of this technique in heart surgery. Our surgeons planned six different heart operations by visualizing computed tomography scans with a dedicated VR headset, enabling them to visualize the patient’s anatomy in an immersive and 3D environment. The outcomes of this preliminary study are positive, with a much more reality-like simulation for the surgeon. In such, VR could potentially be beneficial as a preoperative planning tool for complex heart surgery.

Abstract Introduction Traumatic head injury with extradural hematoma (EDH) is seen in 2% of patients. Development of EDH on the contralateral side is an uncommon complication that has been reported in various case reports. Case Report We report here a case of an 18-year-old male who had a road traffic injury. He was diagnosed as a case of left-sided large frontotemporoparietal acute extradural bleed with a mass effect toward the right side. He was managed with urgent craniotomy and evacuation of hematoma. A noncontrast computed tomography (NCCT) scan performed 8 hours after postoperative period showed a large frontotemporoparietal bleed on the right side with a mass effect toward the left side. He was again taken to the operating room and right-sided craniotomy and evacuation of hematoma were performed. A postoperative NCCT scan revealed a resolved hematoma. The patient made a complete recovery in the postoperative period and is doing well. Conclusion Delayed onset epidural hematoma is diagnosed when the initial computed tomography (CT) scan is negative or is performed early and when late CT scan performed to assess clinical or ICP deterioration shows an EDH. The diagnosis of such a condition requires a high index of suspicion based on the mechanism of injury along with fracture patterns. Additionally, change in pupillary size, raised intracranial pressure, and bulging of the brain intraoperatively are additional clues for contralateral bleeding. Neurologic deterioration may or may not be associated with delayed EDH presentation. An early postoperative NCCT scan within 24 hours is recommended to detect this complication with or without any neurologic deterioration.

Diaphyseal Fractures

Background. Unsatisfactory results of treatment, such as delayed consolidation and non-fusion of fractures, the formation of false joints and limb bone defects, have no tendency to decrease. We can assume that one of the leading factors of complications in traumatology is a violation of microcirculation in the affected segment of the limb.Aims. To identify patterns of changes in the parameters of the microcirculatory bed of the damaged segment of the lower limb when fixing bone fragments with a plate with limited contact in the early period after surgery.Materials and methods. In 25 patients, we studied four parameters of microcirculation of the lower limb segment with application of laser Doppler flowmetry. The control group consisted of 25 healthy volunteers, comparable in age and sex with the study group.Results. We found that in the early postoperative period (from the first to the 10th day after the surgery) in patients with diaphyseal fractures of the tibia operated with metal plate with limited contact there was an increase in microcirculation by 75.69 %, an increase in the proportion of the nutritive component of microcirculation compared to the shunt fraction by 24.64 %, as well as an increase in more than one ratio of the amplitude of the heart and respiratory range. All of that indicates a local circulatory disorder in the nutritive arterial hyperemia. We note that the increase in the amplitude of the respiratory component by 17.22 % and the equality of the amplitude of the cardiac range compared with the control group indicate violations of local blood circulation by the type of venous stagnation.Conclusion. On the basis of the results obtained, we note that patients with diaphyseal fractures of the shin bones treated with metal osteosynthesis with a plate with limited contact in the early postoperative period develop a violation of local blood circulation in the stagnant-hyperemic type.

Purpose of the study: to analyze the etiology, diagnostic criteria and results of treatment of life-threatening conditions in pericarditis of different etiologies (based on our clinic materials).Materials and methods. The study included cases of hospitalization of patients with a diagnosis of «Pericarditis» and ICD-10 codes for pericardial diseases for the period from 2009 to 2018. In the course of the work, the history and clinical picture of the disease, laboratory and radiation research methods were analyzed. All patients started treatment of the underlying disease and performed symptomatic therapy, including those aimed at restoring hemodynamics and normalizing water and electrolyte disorders, stopping inflammation and auto-aggression of the immune system. When signs of compression/cardiac tamponade were detected, pericardiocentesis was performed, according to indications, drainage/fenestration of the cardiac sac, pericardiotomy were performed. In the postoperative period was carried out antibacterial and symptomatic therapy.Results. Life-threatening diseases of the pericardium accounted for 32,03% of all patients treated in the hospital for pericarditis. The most frequently detected signs of a hemodynamically significant compression and cardiac tamponade, less often purulent and constrictive P. Isolated 25 patients underwent closed drainage with pericardiocentesis, in 1 case the drainage was supplemented with f ibrinolytic therapy. Sanitation of the cavity and fenestration of the pericardium were carried out in 11 patients, pericardiotomy with notched drainage in 2 patients, thoracotomy with pericardiectomy – 4. In the postoperative period, the symptoms of inflammation were reduced, the level of cardiac enzymes decreased, the electrolyte balance stabilized. Most patients noted a distinct regression of the symptoms of pericarditis and cardiac compression. Recurrent P was noted in 5 cases, deaths occurred in 4 cases (8,16%).Conclusion. Early verification of the diagnosis and timely decompression of the heart with fractional evacuation of the exudate or pericardectomy with respect to the sequence of release of the heart chambers from adhesions and adhesions against the background of complex therapy allows to achieve positive dynamics, and fenestration of the cardiac bag with the formation of a sufficiently sized opening during recurrent fluid accumulation or intrapericardial fibrin. development of severe complications of pericarditis even in patients with multiple concomitant diseases evanii and oncopathology.
