    The article presents the experience gained by orthopedic unit of Saratov Regional Clinical Hospital at knee joint replacement with modern implants. We analyzed use of Zimmer NexGen CR and LPC implants for initial total knee joint replacement in 285 patients. The monitoring continued for 5 years. Good and excellent results were observed in 92% of cases. Pyogenic complications were observed in 2.3% of cases. The article describes the methods of surgical intervention and post-surgical rehabilitation. We consider our experience with Zimmer NexGen LPS and CR knee-joint implants as positive and prospective for further use

    The paper presents theoretical studies of a new deformation process combining the stages of equal-channel angular pressing (ECAP) and the "Linex"scheme. For correct finite element modeling of the process, a technique with sequential input for the calculation of conveyor links is presented. To analyze the efficiency of metal processing, the main parameters of the stress-strain state are considered: equivalent strain, equivalent stress, and average hydrostatic pressure, as well as the deformation force on the main elements of the combined process: pulley, matrix, and conveyor link. To analyze the resulting deformation forces, the stages of pressing in a matrix and compression by a chain conveyor were separately considered. Equations for determining the forces acting on the drive pulley, ECA matrix, and the chain element link were obtained. Comparison of values showed that the force values in the calculation and simulation have a high level of convergence. In all three considered details, the difference value did not exceed 10%. The variational modeling allowed to determine the optimal values of the main technological and geometric parameters of the process. © 2023 Evgeniy Panin et al

    Under our supervision there were 123 patients with terms of supervision till 7 years, with fractures,fracture-dislocations of an area of a shoulder joint and chronic damages of this area. There were 57 men and 66 women. All the patients were from 38 to 83 years old, the average age was 55,8 years. 44 patients had various kinds of an osteosynthesis and 79 - endoprosthesis of a shoulder joint. It was proved, that in patients of the senior age group, the expressed bony rarefication, a heavy accompanying pathology of a shoulderjoint (arthrosis of 2-3 grades, defeat of a joint at a number system diseases, etc.) and also at the treatment of consequences of traumas are unconditional, the preference should be given to endoprosthesis of a humeral joint, as to more effective method of treatment

    Explaining varieties of corruption in the Afghan justice sector

    © 2015 Taylor & Francis. Judicial reform in Afghanistan is seriously undermined by systemic corruption that has resulted in low legitimacy of the state and weak rule of law. This article reviews the main shortcomings in the Afghan justice system with reference to 70 interviews conducted in Kabul. Building on legal pluralism and a political economic approach, the shortcomings and causes and consequences of corruption in the Afghan justice sector are highlighted. These range from low pay, resulting in bribery; criminal and political intrusion into the judiciary; non-adherence to meritocracy, with poorly educated judges and prosecutors; and low funding in the judicial sector resulting in weak case tracking and human rights abuses in the countryside. This is followed by sociological approaches: understanding corruption from a non-Western approach and emphasis on religion, morality and ethics in order to curb it

    MEDIUM-TERM RESULTS OF PRIMARY HIP JOINT REPLACEMENT WITH ZIMMER IMPLANTS, PROVIDING CEMENT-RETAINED RESTORATION AND CEMENT-FREE RESTORATION

    We observed 503 patients with various pathologies of hip joint. 555 interventions with total hip joint replacement were conducted. 52 patients were operated on both sides. Total number of male patients was 219; the number of female patients was 284. Age of patients varied from 18 to 82. 24 patients were under 25 y.o.; 117 patients were 26–40 y.o.; 232 patients were 41-60 y.o.; 130 patients were older than 60. Cement-free restoration of implants took place in 196 cases. Trilogy + VerSys ET combination was used in 156 cases; Trilogy + Alloclassic combination was applied in 40 cases. Hybrid restoration (ZCA + VerSys ET) was used on 297 patients; completely cement restoration (ZCA + CPT) was applied in 62 cases
