Stress - strain analysis of total hip replacement - type Santori
Huťka, Pavel ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
Submitted Diploma thesis deals with stress-strain analysis of deformation proximal end of femur with applied total hip joint endoprosthesis (replacement) – shortcut type. To identify deformation and tensity (stress) was used computational simulation by method of final elements. Have been created two computational models TEP- type Santori and type DePuy Proxima. Geometry model Santori was created on low level model geometry through the use of X-ray photograph. Principle of geometry model type DePuy Proxima was real Femoral stem endoprosthesis which was scanned on scanner ATOS. Geometry of both these replacements were set up in program Rhinoceros 4.0 and then execute in program CatiaV5R17. Data for geometry model of femur were gained from CT chains. Material model of femur have been crated in two variants. The first one looks at structure bone tissues and the second one were created by Gruen´s zones. Femoral Stem was weighted by static equivalent resultant force acting in hip joint. Computational model of system and self solution, including depiction results, was done by ANSYS Workbench 11.0 for four model variants.

Strain stress analysis of hip joint with thinking of wear after total hip endoprothesis
Ebringerová, Veronika ; Valášek, Jiří (referee) ; Florian, Zdeněk (advisor)
The presented work deals with the creation of computational model of total hip endoprosthesis and the subsequent stress-strain analysis. The models of geometry of the pelvis and femur were created on base of CT data. In this model were fitted components od endoprosthesis, i.e. femoral stem and acetabular cup (metal and polyethylene pad) and also cement. On this system was subsequently modelled the rals loads conditions. Just the real loading of the prosthesis leads to the wear. It has a great influence on the quality of bone tissue, what is deteriorated. The deteriorated tissue was simulated under the acetabular component. The behaviour of the whole system is assessed on base of stress-strain analysis. This problems is very topical these days.

Patients' Experience with Pain after Total Hip Replacement Surgery
HAVLÍN, František
Fear of postoperative pain is one of the most important concern of patients undergoing total hip arthroplasty and it is therefore important to address this issue in medical, and nursing care. In this research we focus on how patients experience pain after total hip arthroplasty. The diploma thesis is divided into two consecutive parts, namely the theoretical, and empirical part. The theoretical part describes the current state of total hip replacement, coxarthrosis, and postoperative pain management. From this part it is clear that the treatment of postoperative pain is dominated by pharmacological methods. In the empirical part, hypotheses were established which dealt with the measurement of the intensity of postoperative pain after total hip replacement surgery the use of pharmacological and non-pharmacological methods of pain treatment and the timeliness of postoperative pain relief. In the practical part of the work a quantitative survey was used. A query sheet was created which was then distributed to patients in the orthopedic patient department. The query sheets were filled out in the first, third, and fifth postoperative day and participation in it was voluntary. From a non-standardized query sheet the data were analyzed by statistics and the results are shown graphically in the thesis. The research survey shows that female and male respondents rate postoperative pain in the same way. The gradual reduction of postoperative pain is also the same for both sexes of the respondents. At the initial meeting with postoperative pain the medical staff instructed patients about the possibilities of pain treatment as the use of pharmacological and non-pharmacological pain treatment. In the query sheet the 87 (81 %) respondents choose the combination of both therapies on the first postoperative day. The 101 (94 %) respondents stated that they used 3 or more methods of non-pharmacological pain treatment on the fifth day. Research has shown that patients experienced less pain after surgery every day and the treatment of the postoperative pain was successful in terms of the rate of analgesic administration by a nurse according to the doctor's instruction. The use of non-pharmacological interventions in the treatment of pain also increased every day.

Early rehabilitation after total hip replacement - the difference in patients operated from anterior and anterolateral approach.
Piruchtová, Karolína ; Teyssler, Petr (advisor) ; Ježková, Martina (referee)
Total hip replacement is one of the most common surgeries in orthopedics. Complete hip replacement can be addressed with several different types of surgical approaches. In this work we deal mainly with the anterior and anterolateral approach. The theoretical part of this work summarizes the basic knowledge about the anatomy, kinesiology of the hip joint and the prearthrotic causes leading to complete hip replacement. Furthermore, the types of surgical approaches, types of total endoprostheses are mentioned and the knowledge about soft tissue healing and early postoperative rehabilitation is summarized. The aim of this work is to determine whether rehabilitation will be faster in the first days after surgery in patients operated by the anterior approach, depending on the gentle approach and respect for anatomical structures, compared to the anterolateral approach. We present a group of 24 patients, 12 of whom underwent anterior approach and 12 anterolateral approach. In the practical part we evaluate and compare early postoperative rehabilitation in both approaches. The parameters we evaluate are the muscular strength of abduction, flexion and extension in the hip joint. Furthermore, the passive and active range of motion in the hip joint during abduction, flexion and extension. We also evaluate...

Paraarticular ossifications after total hip replacement. Modalities of preoperative and postoperative reduction interventions
Debre, Ján ; Dungl, Pavel (advisor) ; Tuček, Michal (referee) ; Dufek, Pavel (referee)
1 PURPOSE OF THE STUDY Heterotopic ossification is frequent and well known complication after primary total hip arthroplasty. Prophylaxis is crucial, ohterwise when ossification is matured, the only treatment option is surgical removal during revision hip surgery. Prophylaxis options are pre, peri- and postoperative modalities. Effectiveness of the profylaxis step sis the aim of this disertation. The goal of Study 1 was to prove the positive side effect of tranexamic acid application to reduce the heterotopic ossification ratio after elective total hip replacement. The goal of Study 2 was to prove the reduction in HO ratio with experimental modification of anterolateral approach with electrosurgery. The goal of Study 3 was to detect the knowledge among czech orthopaedic surgeons in ossification issues and compare the results of questionnaire with german results. 2 MATERIAL AND METHODS Study 1 Cohort of 401 total hip replacements were assessed prospectivelly. Stratification of particular degrees in Brooker scale, sex, laterality and fixation type were evaluated. The average follow up was 6,10 year (40m to 113m). Hips from 2012 are referential and hips from 2016 are administered to tranexamic acid procotol. Other secondary prophylactic modalities (farmacoprophylaxy or radiotherapy), tertiary...
