Methods of fixation of the upper limb fractures
Litera, Jan ; Marcián, Petr (referee) ; Florian, Zdeněk (advisor)
The presented bachelor thesis is focused on current methods of a fixation of upper limb fractures. Part of the thesis is a literature review and a description of the upper limb anatomy. This is necessary to solve the problems associated with upper limb fractures. The history of the treatment of upper limb fractures enables to gain an insight and a benefit of the current methods of the fixation of the upper limb. Based on the acquired knowledge, there is created a simple computational model of a humeral fracture fixation using a LCP and a classical plate. The computational model for the specific load models was solved in the Ansys Workbench 18.2 computing system. The biomechanical analysis based on the results presentation of the solution of the described simple model showed differences between the application of the LCP and the classical plate.

Biomechanical study of the upper extremity plates
Linhart, Lukáš ; Marcián, Petr (referee) ; Florian, Zdeněk (advisor)
This work deals with the possibilities and principles of fixation of fractures of the upper limb. It is divided into five chapters. The introductory chapter discusses the biomechanics and its inclusion in contemporary science. The next chapter describes a brief history of healing and fixation of fractures of the upper limb. The third chapter is devoted to the anatomy of the upper limb, knowledge of which is the effective fixation of fractures of the upper extremity necessary. Another chapter is devoted to the classification and description of the type of osteosynthesis internal fixation of the upper limb. Furthermore, this chapter discusses the principles and mechanisms of LCP fixation. The last fifth point is detailed study of specific humeral locking plate. To create a computational model was used SolidWorks software and ANSYS Workbench.

Detection of changes in digital images
Dorazil, Jan ; Kříž, Petr (referee) ; Říha, Kamil (advisor)
This thesis concerns with change detection problematics in digital images captured under indoor conditions with an ordinary integrated camera in two consecutive moments. All challenges that accompany this problem will be discussed, starting with preprocessing and arriving to evaluation of the results. Currently used methods from this field are described and compared with each other such as differencing and LCP (Local Correlation Peak). A novel method, based on LTP descriptors, effectively solving this problem is proposed in this work. The proposed method is then tested on real data. The results of this tests are discussed subsequently. Besides the change detection method a method for parallax error minimization is proposed here.

Biomechanical study on upper extremity fixation
Rafaj, Svatomír ; Marcián, Petr (referee) ; Florian, Zdeněk (advisor)
This bachelor’s thesis deals with fixation and biomechanical aspects of fractures of the upper limb. The first part of the thesis discusses anatomy, knowledge of which is necessary for effective fixation of fractures. It describes the history of inner fixation of fractures and modern curing methods of fractures with a focus on locking compression plates. The second part of the thesis discusses strain-stress analysis of assemblage of humerus and applied locking compression. Computational model was created with the support of ANSYS Workbench 16.0 and SOLIDWORKS 2016 software. Computation was executed by finite element method using ANSYS Workbench 16.0 computational systém.

Fractures of the distal radius as serious geronto-traumatology problem and its possible solutions
Pacovský, Vladimír ; Topinková, Eva (advisor) ; Trč, Tomáš (referee) ; Pilný, Jaroslav (referee)
Fractures of the distal radius are the most common fractures treated at our clinics . It accounts for around 16 % of all fractures. Most often we meet them in two age groups - children and especially in postmenopausal women. In this group the fractures are frequently associated with osteoporosis. The most common cause of fracture is a fall on the outstretched extremity. Together with fractures of the proximal humerus, proximal femur and vertebral fractures they are the most common gerontotraumatologic fractures. The frequency of fractures of the distal radius gradually increasing. The reason is the increasing average age of the population and their active way of life. Our group consists of 5,359 patients treated for a fracture of the distal radius in 1998 and from 2001 to 2013 . During this time , the frequency of fractures increased by 19,7%. For women with distal radius fractures occur 3 times more frequently, the average age of treated was 59,1 years. About 80 % of distal radius fractures are treated conservatively. The surgical treatment of seniors decide not only the type and stability of the fracture, bone quality, but especially the overall condition of the patient and his claims to a final functional outcome. Long-term functional results after conservative treatment in the elderly are nearly the...
