To, jak se bude implantát chovat v lebce, je velmi důležitým faktorem, který ovlivňuje jeho funkci. K ovlivnění dochází především vnějšími silami a nitrolebečním tlakem. Tato zatížení mohou způsobit pohyb implantátu a poškození živých tkání. Tato práce shrnuje poznatky a analýzy, týkající se rekonstrukce poranění lebky. Srovnání implantátů z různých materiálů a fixátorů je založené na napěťově-deformační analýze implantátu, zatíženého vnějšími silami a nitrolebečním tlakem.

Title: Electromyographic Analysis of the Different Handlebars Grips Effect on the Shoulder Blade Fixators Aims: The main objective of this thesis is to carry out a methodological study on the impact of different handlebars grips on the shoulder blades fixators. Result of the grip change is not only reduction of the upper fixators activity and the increase in the lower fixators activity but also co-contraction index increase and muscle fatigue reduction. Based on the hypothesis we assumed that the highest activity rate of the lower blades fixators and the lowest activity rate of the upper blades fixators will be during the handlebars brakes grip. The highest co- contraction index will occur during the handlebar brakes grip and the maximum muscular fatigue will occur during the grip at the top of the handlebars. The first part of the thesis is focused on the literature search and facts retrieval pertaining to the studied issue. In the second special part of the thesis we conducted a research during which the muscle activity of the upper and lower blade fixators was recorded. Three different handlebars grips were considered during the measurement using the cycle ergometer. Methods: Muscle activity was scanned and recorded using surface EMG. Maximal voluntary contraction of selected muscles based on...

Name: The Effect of Facilitating Kinesio Taping of lower scapula fixators on pain threshold of trigger points in the m. trapezius pars descendens Objectives: This study is a pilot study. The goal of this study is to determine effects of Facilitating Kinesio Taping of lower scapula fixators on painfulness of trigger points in the m. trapezius pars descendens. Methods: The study took place in a private medical office with thirteen patients. All of these patients were physically examined using standard tests of physiotherapy. Patients were measured using a pressure algometer to assess trigger points as painful. They reported the intensity of pain on VAS. The places of measurement were trigger points one and two in the muscle according Travell and Simons. Data were analyzed using the statistical program SPSS 15.0 and Microsoft Office Excel. Results: This study had three hypotheses. In the case of the first hypothesis, I concluded that KT has an effect on the pain threshold and its application will reduce the pain threshold in m.trapezius pars descendens. Statistical significance was the value of p = 0.03 and p = 0.011, the value of material significance (101.31 kPa and 106.7 kPa) confirmed my theory that after KT will increase the pressure of 100 kPa in the TrP1 and TrP2. In the second hypothesis, it...

A distração osteogênica tem sido extensamente empregada na correção da grave hipoplasia do terço médio da face de portadores de craniossinostose sindrômica. Contudo, poucos estudos têm apresentado os resultados da distração do terço médio da face através de avaliação cefalométrica. O objetivo do presente estudo foi o de avaliar os resultados obtidos com o avanço ósseo do terço médio da face após osteotomia tipo Le Fort III ou frontofacial em monobloco seguida da utilização de dispositivo rígido externo de distração (RED), em portadores de craniossinostose sindrômica, em termos de quantidade de alongamento ósseo, estabilidade esquelética e crescimento facial. Onze pacientes submetidos aos procedimentos de distração, de fevereiro de 2002 a janeiro de 2006, na unidade de cirurgia plástica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, foram avaliados retrospectivamente. Seis pacientes eram portadores da síndrome de Crouzon, quatro da síndrome de Apert, e um da síndrome de Saethre-Chotzen. Onze pacientes foram submetidos ao procedimento de alongamento ósseo do terço médio da face através do uso de dispositivo externo rígido (RED), após osteotomias tipo Le Fort III (N = 4) ou frontofacial monobloco (N = 7). Foram avaliadas retrospectivamente três telerradiografias de face em norma lateral de cada paciente (T1- préoperatório; T2 - pós-operatório recente, logo após a remoção do distrator; T3 - pós-operatório tardio, obtida com um intervalo mínimo de 12 meses após cirurgia). Três cefalogramas foram obtidos de cada paciente, através da direta sobreposição das três telerradiografias, tomado como referência reparos anatômicos do crânio e da porção anterior da fossa craniana. Desta forma, os três traçados cefalométricos foram obtidos no mesmo papel acetato, o qual foi digitalizado. Utilizando o programa de computação gráfica de domínio público Image J, várias mensurações foram realizadas com a intenção de determinar a extensão do avanço sofrido pelos segmentos ósseos na direção do vetor do movimento esquelético, assim como de seus componentes horizontal e vertical, tomando como referência pontos A e orbitário. Pacientes foram ainda divididos em dois grupos (G 1 - pacientes submetidos à osteotomia tipo Le Fort III; G 2 - pacientes submetidos à osteotomia frontofacial em monobloco), e os dados obtidos a partir mensurações de ambos os grupos foram comparados. Avanço significativo do terço médio da face foi obtido com os procedimentos. O componente horizontal do movimento esquelético predominou ao componente vertical. A taxa de reposicionamento posterior horizontal tardio (perda de resultado) foi mínima. Quando comparados os dois procedimentos, foi observada uma diferença significativa entre os grupos Le Fort III e monobloco. A quantidade de avanço obtido foi maior no grupo monobloco que no grupo Le Fort III. Em termos perda de resultado, o grupo Le Fort III foi mais estável que o grupo monobloco. Foi observada uma evidente alteração vertical no posicionamento dos pontos de referência no pós-operatório tardio, se comparado ao pós-operatório recente, evidenciando crescimento na vertical da face, ao contrário do que ocorre na direção horizontal, onde existiu um pequeno reposicionamento posterior e nenhuma evidência de crescimento. / Distraction osteogenesis has been applied extensively to correct the severe midface hipoplasia in syndromic craniosynostosis patients. However few studies have reported midface distraction outcomes through cephalometric evaluation. The purpose of the present study was to evaluate outcomes with midface distraction after Le Fort III and frontofacial monobloc osteotomy using a rigid external device (RED) in patients with syndromic craniosynostosis, in terms of quantity of bone lengthening, skeletal stability and facial growth. Eleven patients underwent to midface distraction from February of 2002 to January of 2006 at the plastic surgery unit of The \'Hospital das Clínicas\' of the Medical School of The University of São Paulo were retrospectively evaluated. Six patients had Crouzon, four had Apert, and one had Saethre-Chotzen syndrome. The patients were submit to bone lengthening procedure of the midface using a rigid external device (RED) after osteotomy type Le Fort III (n=4) and frontofacial monobloc osteotomy (n=7). Three teleradiography were retrospectively evaluated of each patient (T1 - before surgery; T2- after surgery, rigth after distractor removal; T3 - after surgery, obtained with a minimal interval of 12 months after surgery). The three lateral cephalograms were obtained from each patient by direct teleradiography superimposition taken as references the anatomic repairs in the cranium and anterior skull base. This way the three cephalometric tracings were obtained in the same acetate paper which was digitalized. Utilizing a public domain program Image J, various mensurations were accomplished with intension of determine the extent of advancement suffered by the bone segments in the direction of vector skeletal movement and its horizontal and vertical components as well, as taken as references point A and orbitale. Patients still were divided between two groups (G 1- patients submitted to an osteotomy type Le Fort III; G 2- patients submitted to monobloc frontofacial osteotomy), and the data obtained from mensurations from both groups were compared. Significant midface advancement was achieved with the procedures. The horizontal component of the movement was predominant if compared to vertical. The rate of horizontal relapse was minimal. When compared the two procedures was noted a significant difference between Le Fort III and monobloc groups. The advancement rate was greater in monobloc than Le Fort III group. In terms of relapse Le Fort III group was more stable than monobloc group. In vertical direction was noted an evident altered position of the reference points at late postoperative period if compared with recent postoperative period given evidence of facial vertical direction growth, contrary from what occurred in horizontal direction where existed a small relapse and no growth.

<p>Kompleksnost visokoenergetskih preloma platoa i pilona tibije i njihova udruženost sa značajnim povredama mekog tkiva oko pripadajućeg zgloba veoma je dobro opisana. Lečenje ima za cilj da multifragmentarni prelomi platoa i pilona tibije postanu stabilni, artikularno poravnani, bezbolni, da koleno i skočni zglob budu pokretni i da se minimizira rizik do nastanka posttraumatskog osteoartritisa. Aparat po Ilizarovu sa nategnutim iglama, koristi opterećenje da stvori jedinstvenu podr&scaron;ku za zglob i stabilnu imobilizacju preloma da se postigne njegovo srastanje. Ovo omogućuje ranu pokretljivost zgloba bez rizika od gubitka redukcije. Cilj istraživanja je procena i poređenje rezultata lečenja unutarzglobnih vi&scaron;ekomadnih preloma kostiju proksimalnog i distalnog okrajka potkolenice tretiranih spoljnjim unilateralnim rigidnim fiksatorom i aparatom po Ilizarovu primenom ASAMI ko&scaron;tanog skoring sistema i funkcionalnog skoring sistema po Karlstrom &ndash; Olerudu.Takođe je jedan od ciljeva istraživanja bio da se uoče faktori koji utiču na različite rezultate lečenja unutarzglobnih vi&scaron;ekomadnih preloma kostiju gornjeg i donjeg okrajka potkolenice tretiranih spoljnim unilateralnim rigidnim fiksatorom i aparatom po Ilizarovu. Istraživanje je dizajnirano kao kontrolisana komparativna klinička studija a podaci su se prikupljali retrospektivno i delom prospektivno na osnovu medicinske dokumentacije od 2008. do 2013. godine. Studija je u potpunosti izvedena na Klinici za ortopediju i traumatologiju Kliničkog centra Vojvodina u Novom Sadu. Studija je obuhvatila ukupno 103 ispitanika kod kojih je u toku 2008 do 2013. godine postavljena dijagnoza unutarzglobnog vi&scaron;ekomadnog preloma gornjeg ili donjeg okrajka tibije. Ispitanici koji su obuhvaćeni ovim kliničkim istraživanjem razvrstani su u tri grupe: Prvu grupu od 53 ispitanika činili su oni sa vi&scaron;ekomadnim unutarzglobnim otvorenim ili zatvorenim prelomima gornjeg ili donjeg okrajka kostiju potkolenice lečenih isključivo spoljnjim unilateralnim rigidnim fiksatorom. Drugu grupu ispitanika, njih 31, činili su oni sa vi&scaron;ekomadnim unutarzglobnim otvorenim ili zatvorenim prelomima gornjeg ili donjeg okrajka kostiju potkolenice lečenih isključivo aparatom po Ilizarovu. Treću grupu činila su 19 ispitanika sa vi&scaron;ekomadnim unutarzglobnim otvorenim ili zatvorenim prelomima gornjeg ili donjeg okrajka kostiju potkolenice koji su lečenje započeli spoljnjim unilateralnim rigidnim fiksatorom, a u kasnijem periodu zbog nastalih komplikacija (lo&scaron;e srastanje, produženo srastanje, nesrastanje, infekcija, pseudoartroza) lečenje nastavili konverzijom spoljnjeg unilateralnog rigidnog fiksatora u aparat po Ilizarovu. Osnovni izvor podataka za prikazano istraživanje bio je protokol formiran za svakog bolesnika pojedinačno, istorije bolesti i poliklinička evidencija. Za potrebe istraživanja dizajniran je protokol istraživanja gde su se prikupljeni podaci analizirali hronolo&scaron;ki : podaci o pacijentu, klinički nalaz na prijemu, postoperativni tok, monitoring aparata, klinički nalaz na otpustu i klinički nalaz na kontrolama od 6, 12 i 18 meseci. Kliničke nalaze na kontrolama na 6, 12 i 18 meseci beležili smo upotrebom skoring sistema ASAMI ( Udruženja za istraživanje i primenu metoda po Ilizarovu) &ndash; za ko&scaron;tane rezultate, i Karlstrom &ndash; Oleruda za procenu funkcionalnih rezultata. Neki do najvažnih rezultata dobijenih prilikom ovog istraživanja jesu da je najbrže vreme srastanja imala grupa Ilizarov, nakon 16&plusmn;2 nedelja. Grupa konverzija zabeležila je prosečno vreme srastanja u 17&plusmn;2 nedelji, dok je kod ispitanika u grupi fiksator zabeženo srastanje u 21&plusmn;4 nedelji. Pojava povr&scaron;nih i dubokih infekcija značajno je veća kod grupe tretiranih spoljnim unilateralnim fiksatorom nego kod grupa tretiranih aparatom po Ilizarovu. Vreme postizanje ranog, punog oslonca na operisani ekstremitet je značajno kraće kod grupe Ilizarov i konverzija nego kod grupe fiksator. Procena ko&scaron;tanih rezultata kori&scaron;ćenjem ASAMI bodovnog sistema ko&scaron;tanog srastanja ukazuje na statistički značajno bolje rezultate kod grupa Ilizarov i konverzija u odnosu na grupu spoljnji fiksator u periodu praćenja i analize na 6,12 i 18 meseci. Funkcionalni rezultati primenom sistema funkcionalne evaluacije po Karlstrom &ndash; Olerudu govore u prilog značajno statistički boljim rezultatima kod grupe Ilizarov i konverzija u odnosu na grupu spoljni fiksator u periodima praćenja i analize na 6,12 i 18 meseci. Na osnovu dobijenih rezultata dolazimo do zaključka da je tretman ispitanika sa multifragmentarnim, intraarikularnim prelomima gornjeg i donjeg okrajka kostiju potkolenice znatno efikasniji aparatom po Ilizarovu &scaron;to sveukupno daje smernice za brži i kvalitetniji oporavak ispitanika i njihov povratak svakodnevnim aktivnostima sa &scaron;to manjim posttraumatskim sekvelama.</p> / <p>The complexity of high-energy fractures of the tibia plateau and pilons and their association with significant violations of the soft tissue around the corresponding joint is well described in the literature. Main aim of the treatment is to multiple fractures of the tibia plateau and pilon become stable, articularly aligned, without pain, and with full motion in the knee and ankle joint with minimum risk for post-traumatic osteoarthritis. Ilizarov apparatus with taut needles is used to create a unique load support for the ankle and create conditions for good healing. This strong stability allows early joint movement, without risk of loss position of fracture parts. The aim of this research is assessment and comparation of the results of treatment, for intraarticular multiple fractures of the proximal and distal part of lower leg tretaed with unilateral external rigid fixator and Ilizarov apparatus, with ASAMI bone scoring system and functional scoring sistem by Karlstrom &ndash; Olerud. One of the goals of the study was to detect factors which affecting different treatment results of the intraarticular multiple fractures of the proximal and distal part of lower leg, tretaed with unilateral external rigid fixator and Ilizarov apparatus. The study was designed as a controlled comparative clinical study and data were collected retrospectively and prospectively form medical records from 2008 to 2013. The study has been fully implemented at the Department for orthopedic surgery and traumatology in the Clinical Center of Vojvodina in Novi Sad and included 103 patients who had intraarticular multiple fractures of the proximal and distal part of tibia. Subjects covered in this clinical study were classified into three groups: The first group of 53 patients were with intraartiulary multifragmentary open or closed fractures of the upper or distal part of lower leg, treated exclusively with unilateral external rigid fixator. The second group included 31 patients with intraarticular open or closed fractures of the upper or distal lower leg, treated exclusively with Ilizarov apparatus. 19 patients made the third group with intraarticulary open or closed fractures of the upper or distal lower leg, which were treated at the begining with unilateral external rigid fixator and later because of the complications (poor or prolonged healing, nonunion, infection and pseudoarthrosis) tretment was continued by Ilizarov apparatus. The main source of data for this study was protocol wich was established for each patient individually. In this protocol collected data analyzed by date: patient data, clinical findings at admission, postoperative course, monitoring apparatus, clinical findings at discharge and clinical findings at the controls which were at 6, 12 and 18 months after surgery. Clinical findings at control examinations (6, 12 and 18 months after surgery), we recorded by scoring system ASAMI (Association for the Study and Application of the Methods of Ilizarov) - that represent the results of the bone healing, and Karlstrom - Olerud for assessment functional outcomes. The most important results were: the fastest time of bone union was in the group of Ilizarov, and it was after 16 &plusmn; 2 weeks and the third group (conversion group) recorded an average time after 17 &plusmn; 2 weeks, while the patients in the first group (external fixator) had average time of union after 21 &plusmn; 4 week. The appearance of superficial and deep infection was significantly higher in the group treated with unilateral external fixator than in the group treated by the Ilizarov apparatus. Fastest full weight bearing on the injured leg, had patients in the group treated with Ilizarov apparatus. Evaluation of results using bone ASAMI fusion scoring system indicating a statistically significantly better results in the conversion and Ilizarov group compared to the group of external fixator in the period of monitoring at 6,12 and 18 months after surgery. Functional results by Karlstrom - Olerud scoring system show statistically significantly better results in the Ilizarov and conversion group contrary to the external fixator group in periods of monitoring at 6,12 and 18 months. Based on these results we conclude that the treatment of subjects with intraarticulary, multifragmentary fractures of the upper and lower part of the lower leg are more efficient after Ilizarov apparatus which provides overall guidance for faster and better recovery of patients and their return to their daily activities with minimal post-traumatic sequelae.</p>

INTRODUÇÃO: A instabilidade multiligamentar do joelho, normalmente, é provocada por um trauma que determina sua luxação, um evento pouco frequente, mas, que pode trazer sequelas devastadoras. Mesmo com o tratamento cirúrgico preconizado é alto o índice de complicações. A mobilização precoce no pósoperatório provoca afrouxamento dos ligamentos reconstruídos, o que leva à instabilidade residual. A imobilização melhora a estabilidade, mas provoca dor e rigidez. Este trabalho tem o objetivo de avaliar se o uso do fixador externo articulado proporciona melhora na mobilidade, estabilidade e na função subjetiva de pacientes submetidos à reconstrução ligamentar. MÉTODOS: Neste ensaio clínico randomizado com grupos paralelos, 33 pacientes do ambulatório do Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Universidade de São Paulo com mais que 3 semanas de lesão dos ligamentos cruzados anterior e posterior associado à lesão de ligamento colateral fibular e/ ou ligamento colateral tibial foram submetidos à cirurgia de reconstrução multiligamentar, após alocação cega aleatória ao grupo 0 - controle (18 pacientes), com órtese rígida ou ao grupo 1 - fixador externo articulado por 6 semanas (15 pacientes), no período entre novembro de 2010 e novembro de 2013. Após seguimento mínimo de um ano de pós-operatório, a estabilidade dos ligamentos reconstruídos foi avaliada ao exame físico, foram mensurados os déficits de extensão e de flexão residual em relação ao joelho contralateral não acometido e foi aplicado o questionário específico para sintomas do joelho de Lysholm. RESULTADOS: Não houve diferença na avaliação da estabilidade articular nem na extensão entre os grupos. No grupo 1, o déficit de flexão passiva foi menor (4,8º +- 5,4º contra 18,2 +- 14,8º, p < 0,05) com mais pacientes, obtendo déficit de flexão considerado normal, de até 5º (64% contra 18%, p < 0,05) e com classificação excelente ou boa no questionário de Lysholm (73% contra 35%, p < 0,05). CONCLUSÕES: Comparado ao protocolo de reabilitação com órtese rígida removível, o uso do fixador externo articulado no tratamento cirúrgico das lesões multiligamentares do joelho proporciona os mesmos resultados de estabilidade ligamentar, aumenta a amplitude de movimento final, com manutenção da extensão e redução do déficit de flexão e proporciona melhores resultados funcionais / INTRODUCTION: Multiligament knee instability is normally caused by a trauma which results in its dislocation, an infrequent event, but one which can have devastating aftereffects. Even with the recommended surgical treatment the rate of complications is high. Early post-operative mobilization provokes loosening of the reconstructed ligaments, which leads to residual instability. Immobilization improves the stability, but causes pain and stiffness. This study aims to assess whether the use of an articulated external fixator provides improvements in the mobility, stability and the subjective function of the patients submitted to ligament reconstruction. METHODS: In this randomized clinical trial with parallel groups, 33 patients of the outpatient clinic of the Institute of Orthopaedics and Traumatology of the Hospital das Clínicas of the University of Sao Paulo with more than 3 weeks of injury to the anterior cruciate ligaments and the posterior cruciate ligaments associated with injury to the fibular collateral ligament and/or medial collateral ligament, were submitted to multiligament reconstruction surgery, after blind random allocation to either: Group 0 - control (18 patients), with rigid bracing, or to Group 1 - articulated external fixator for 6 weeks (15 patients), in the period from November, 2010 to November 2013. The stability of the reconstructed ligaments were assessed after 1 year postoperatively by physical examination, the deficit of residual extension and flexion was measured in relation to the unaffected contralateral knee and the Lysholm knee scoring scale questionnaire was applied. RESULTS: There was no difference in the assessment of joint stability or of the extension between the groups. In group 1 the passive flexion deficit was less (4.8º +- 5.4º versus 18.2 +- 14.8º, p<0.05) with more patients obtaining a flexion deficit considered normal, or up to 5º (64% versus 18%, p<0.05) and with excellent or good classification in the Lysholm knee scoring scale questionnaire (73% versus 35%, p<0.05). CONCLUSIONS: Compared to the rehabilitation protocol with removable rigid bracing, the use of an articulated external fixator in the treatment of multiligament knee injuries provides equal results for ligament stability, increases the amplitude of the Range of Motion, maintains the extension and reduces the flexion deficit, and provides better functional result

In group 1 the passive flexion deficit was less (4.8º +- 5.4º versus 18.2 +- 14.8º, p<0.05) with more patients obtaining a flexion deficit considered normal, or up to 5º (64% versus 18%, p<0.05) and with excellent or good classification in the Lysholm knee scoring scale questionnaire (73% versus 35%, p<0.05). CONCLUSIONS: Compared to the rehabilitation protocol with removable rigid bracing, the use of an articulated external fixator in the treatment of multiligament knee injuries provides equal results for ligament stability, increases the amplitude of the Range of Motion, maintains the extension and reduces the flexion deficit, and provides better functional result

Thesis title: Effect of targeted training of the lower scapular fixators on the shoulder girdle function of rugby players The concept of the problem: Rugby is one of the toughest ball sports and there is no shortage of injuries. In addition, injuries in the shoulder area are among the most common and any possibility of reducing these injuries is beneficial. There is not much time left for compensation and targeted intervention; moreover, it is not usually led by physiotherapists but by fitness coaches and only in larger clubs. The consequence is a muscle imbalance in the shoulder girdle, which can result in the so-called scapular dyskinesis. This is turn affects the function and stability of the shoulder joint not only by the overhead athletes. It is possible to influence scapular dyskinesis in various ways. One of them is the inclusion of targeted training of lower scapular fixators into fitness training and thus their stability is improved. Objectives: The main aim of this thesis is to verify whether rugby players with painful shoulder have sufficiently scapular fixation based on kinesiological and biomechanical knowledge. Another aim of this thesis is to create such an exercise unit that would ensure the correct activity of the lower scapular fixators and verify this by measurement. The final...
