Biomechanical Study of Hand
Krpalek, David ; Janíček, Přemysl (referee) ; Horyl, Petr (referee) ; Florian, Zdeněk (advisor)
This work deals with issue of human wrist and appropriate total wrist implant allowing a restoration of hand mobility approaching physiological condition after traumatic and degenerative diseases. Treating these diseases are very complex. These issues including a biological and medical issues. To determine the appropriate treatment method and select right total wrist implant is important to know the behavior the human wrist at all stages in terms of medical and biomechanical. For this reason, it was developed a biomechanical study including computation model of human wrist allowing solution of strain and stress of hand in physiological and pathological conditions and condition after total wrist implant. The frost remodeling of bone tissue was used for analysis of human wrist bone tissues and bone tissues after application of total wrist implant RE-MOTION™ Total Wrist.

Stress-strain Analysis of Chosen Spinal Fixation Device
Prášilová, Eva ; Valášek, Jiří (referee) ; Marcián, Petr (advisor)
The degenerative and traumatic injuries of a spine are very frequent. In those cases it is necessary to stabilize the corresponding spine segment using a spine implant. The spinal implants are rigid or flexible, the latter known as dynamic ones in medical practice. In this thesis, the problems of the physiological spinal segment and the segment with implant were solved using the computational modelling (finite element method). Computational model consists of 4 lumbar vertebrae L2 – L5, intervertebral discs, joints and spinal implants. The spinal segment was loaded by the force 400N and 200N, than by force 200N together with bending moments 2,5Nm and 5Nm depending of the motion. The displacement of the whole system, contact pressure of cartilages, equivalent strain in cancellous bone and equivalent stress in the implant were analyzed. The deformation of the physiological model and the model with the implant are comparable, but the bone tissue of the model with the implant is dramatically more loaded in vicinity of the screws.

Methodical procedures and comparison of various techniques of taping in the area of the knee joint
SYROVÁTKA, Tomáš
This bachelor thesis has theoretical and didactic character and it concerns with methodical procedures of taping in the area of a knee joint. Analytical part was made on basis of analysis of scientific literature, and it contains detail description of anatomy, kinesiology, and the most frequent injuries of the knee joint. In the thesis there is also described method of taping itself, division of the taping tapes on flex and stiff tapes. Next there are described concrete methods of taping, functionality, and principles of correct taping. Crucial part of this thesis is synthetic part. There are described and compared methodical procedures of taping in a knee joint. Compared methods were complete stabilization, lateral ligaments, patella and taping of injured ACL. Part of the synthetic part is photodocumentary of the procedures with stiff and flex tapes with detail description of the procedures. There is also comparison of the taping methods. The final result could serve as a tool for sport trainers or individuals, who are devoted to regeneration or to sport itself.
