Muller, BurchSchneider, rings of PROTEK (Switzerland) implanted in the BB. In traumatology practice, rings are used to strengthen fractured walls. However, these rings are not functionally designed for open reposition and fixation of columns and fractures, followed by TBS endoprosthetics with cement fixation of the components of the endoprosthesis. Recently, primary endoprosthetics of EP TBS became the trend for displaced fractures of the BB, which is considered the best option for surgical treatment of BB fractures. In the literature, no analogs of our ring were available, which provides CHP in the treatment of BB fractures. \u0000AIM: To study the deformation properties of a repositional fixation ring with an outer diameter of 52 mm with a stiffening rib. \u0000MATERIALS AND METHODS: A ring has been developed for the surgical treatment of acetabulum fractures (Patent for Invention No. 2692526 dated 26.06.2019 under Application No. 2018133671 dated 25.09.2018.; Bul. No. 18 dated 26.06.2019). For mechanical testing, a ring with an outer diameter of 52 mm with a stiffening rib was manufactured by sequential sintering using additive technologies by Konmet LLC (Moscow). Laboratory mechanical tests were conducted by the Testing Laboratory of Medical Devices and Materials of the FSBI NMIC TO named after N.N. Priorov (Moscow). \u0000RESULTS: A static testing of a ring with a stiffener for compression, stretching, torsion, joint stretching, and twisting of the edges of the ring connector was performed, and its deformation properties and reaction to external loads during static tests were examined. The load corresponded to the deformation of 2 mm, kN; compression, 0.209; tension, 0.082; torsion (angle of rotation of 5 degrees, Nm), 9.422; and joint stretching with twisting of the edges of the ring connector (load corresponding to the deformation of 10 mm, kN), 0.060. \u0000CONCLUSION: The results of the initial study of the deformation behaviors of the new ring design clearly show the elastic nature and deformation properties of the ring, which were attributed to the stiffening rib. The positive primary results of studying the deformation behaviors of the ring reinforced with a stiffening rib indicate the possibility for clinical trials and the direction of further refinement of the design..","PeriodicalId":308632,"journal":{"name":"N.N.

One of the effective methods of treating MPSF in pediatric patients is an arthroscopic excision of the fold. \u0000AIM: Evaluation of long-term results of arthroscopic treatment of patients with pathologically thickened MPSF of the knee joint. \u0000MATERIALS AND METHODS: There was conducted an analysis of primary medical documentation, which included the study of hospital records and case histories of 73 patients. The survey questionnaires (based on VAS and WOMAC scales) were sent to these patients. Responses were received from 35 patients who were included in the study. \u0000RESULTS: When evaluating the long-term results of surgical intervention in 35 operated patients in 29 (82.1%) patients, it was found out that there were no exacerbations in postoperative period and, at the time of the data collecting, there weer no complaints for the pain syndrome. Dysplasia of the femoral condyle of type A and B was diagnosed in these patients. At the time of the evaluation, 6 (18.9%) patients had pain syndrome with decreased function of the knee joint. In these patients, dysplasia of the femoral condyle corresponded to type C in 4 cases, types D and B in 1 case. \u0000CONCLUSION: At the early stages of the disease, it is necessary to carry out a detailed differential diagnosis to identify the pathology of the knee joint. Attention should be paid to the combination of a pathologically thickened MPSS with dysplasia of the femoral condyle, which can lead not only to complications of conservative therapy and ineffectiveness of surgery, but also to the development of patellofemoral arthrosis.","PeriodicalId":308632,"journal":{"name":"N.N.

Strunina","doi":"10.17816/vto105177","DOIUrl":"https://doi.org/10.17816/vto105177","url":null,"abstract":"BACKGROUND: The measurement of sagittal parameters is an important part of preoperative planning and is also used to evaluate the results of surgical treatment. It is known that in spondylolisthesis (especially at high degrees) the sagittal parameters of the spine differ from those in healthy people. The difference in spinal-pelvic parameters in children and adults without orthopedic pathology has also been proven. One of the tasks of surgical treatment of spondylolisthesis is the restoration of sagittal balance or its maximum approximation to normal values. However, today there is no single accepted norm of sagittal parameters for children, therefore, the question of the optimal tactics of surgical treatment of spondylolisthesis in children remains open. \u0000AIM: To determine the parameters of the sagittal balance in normal children and in children with spondylolisthesis. \u0000MATERIAL AND METHODS: A retrospective analysis of postural radiographs of 68 children was performed. Patients were divided into 2 groups: group I 43 patients from 8 to 17 years old without spinal pathology. Group II 25 patients with spondylolisthesis from 8 to 17 years old. For each patient, the main spinal and pelvic parameters (PT; PI; SS; LL; PI-LL; TK) were measured and statistical analysis of the data was performed. \u0000RESULTS: The study proved that the main parameters of the sagittal balance (PI, PT, SS, LL, TK, PI-LL) in children and adults without pathological deformities of the spinal column are statistically significantly different. Also, there are statistically significant differences between the parameters of the sagittal balance in children and adolescents without spinal pathology and with spondylolisthesis (PI, PT, SS, LL, TK, SFD, PI-LL). In patients with high grade spondylolisthesis, the parameters of thoracic kyphosis and lumbar lordosis are significantly reduced, which should be assessed as a compensatory mechanism for maintaining the vertical position of the body. Children with spondylolisthesis are characterized by a significantly higher PI value. \u0000CONCLUSION: The sagittal parameters of the spine in children and adults are different, therefore, for correct preoperative planning, it is necessary to establish the norm of sagittal parameters for children. It is also necessary to take into account the high value of PI in children and adolescents with spondylolisthesis, which may be the etiological factor of this disease. The existing formulas for measuring sagittal balance for children with spondylolisthesis should be used with caution, because a high PI can lead to unreliable theoretical values of PT, SS, LL and TK. The cause of sagittal imbalance can be not only high degrees of spondylolisthesis, but also the tight hamstrings.","PeriodicalId":308632,"journal":{"name":"N.N.

The аnimals underwent discectomy at the level of L45, L56 vertebrae through the lateral approach on the right, and interbody titanium implants were installed. The lumbar spine was stabilized with an external fixator for 30 days.
