Ortopedi - patofysiologi, sjukdomar och trauma hos barn och vuxna är en omfattande grundbok i ortopedi som ger en aktuell introduktion till fältet.Boken är uppdelad i tre delar. Del ett behandlar historik, epidemiologi, muskuloskeletal biologi, klinisk undersökningsteknik och diagnostik samt generella problem, frågeställningar och sjukdomar inom ortopedin. Del två går i olika kapitel systematiskt igenom kroppens regioner vad gäller ortopediska sjukdomar och trauman hos vuxna. I varje kapitel används genomgående rubrikerna bakgrund, symptom, diagnostik, behandling samt prognos. I del tre upprepas denna struktur vad gäller barnaårens ortopediska sjukdomar och trauman. Samtliga delar innehåller rikliga illustrationer som kompletterar texterna.Ortopedi - patofysiologi, sjukdomar och trauma hos barn och vuxna är framför allt avsedd för läkarstudenter, utbildningsläkare samt specialistläkare som handlägger ortopediska sjukdomar och skador. Boken kan med fördel även användas av annan vårdpersonal som är engagerad i utredning och behandling av ortopediska sjukdomar och trauman.

Styrketräning kan utövas som en egen idrott i form av tyngdlyftning och styrkelyft. Styrketräning bedrivs också i prestationshöjande syfte som ett viktigt komplement till andra träningsformer eller idrotter. Många styrketränar för att orka mer och klara vardag och fritid bättre. Sist men inte minst spelar styrketräning en viktig roll i att förebygga och behandla skador och sjukdomar. Styrketräning är inkluderande och kan utformas så att vem som helst, oberoende av ålder och fysisk status kan utföra den. Styrketräning är också skonsam och anpassningsbar och därför alltid ett alternativ när andra träningsformer blivit för krävande och inte längre fungerar att utföra. Styrketräning är dessutom en effektiv och utmanande träningsform, på kort tid kan man pressas till total utmattning. Det är alltså inte så konstigt att styrketräning är en av de vanligaste träningsformerna och idag har mer än två miljoner utövare i Sverige. Och i takt med att intresset för styrketräning ökar, så bidrar forskningen till att kunskapen om kropp och muskler också ökar. Denna bok är den mest heltäckande och ambitiösa om styrketräning som skrivits i Sverige och ger såväl kunskap som vägledning kring hur styrketräning ska bedrivas för att ge optimal effekt utifrån träningens syfte. Boken är indelad i olika kapitel som behandlar många olika aspekter av styrketräning. För att öka förståelsen och för att göra läsningen så stimulerande som möjligt är boken rikt illustrerad och försedd med faktarutor och sammanfattningar. Den nya upplagan av boken har både uppdaterats och utökats med nya forskningsrön, aktuella referenser och information i samtliga kapitel. Den tillämpade delen av boken har ytterligare fördjupats med nya bilder där de mest betydelsefulla styrketräningsövningarna demonstreras på ett unikt och pedagogiskt sätt för läsaren. Kapitlen Styrketräning för unga, gravida och äldre, Förebyggande och rehabiliterande styrketräning och Kostens betydelse vid styrketräning har alla nytt innehåll. Ett helt nytt kapitel, Träningsplanering och tester för styrketräning, har tillkommit. Styrketräning – för idrott, motion och rehabilitering riktar sig bland annat till aktiva och ledare inom idrottsrörelsen, hälso-, friskvårds-, gym- och fitnessbranschens aktörer och till utbildningar av fysioterapeuter, idrottsvetare, hälsovetare, biomedicinare, idrottslärare med flera.

Den vuxna människokroppen är uppbyggd av mer än 200 ben vilka har den gemensamma egenheten att samtliga kan frakturera, på olika sätt och på olika ställen. Varje enskild fraktur kan sedan presentera sig med varierande symptom, ha varierande grad av instabilitet, variera i betydelse för kroppens funktion och ha varierande läkningstider. Vid tillägg av samtliga ledbands- och ledkapselskador; stukningar och luxationer; muskel- och senskador går det att ana att antalet möjliga ortopediska skador är enormt och nästintill omöjligt för den enskilde läkaren att kunna i detalj. Boken Traumaortopedi är unik så till vida att samtliga ortopediska skador är beskrivna, dels avseende utseende, uppkomstmekanism och symtom, dels att det för varje enskild skada finns en beskriven klassificering följt av en specifik behandlingsalgoritm. Med den här boken som stöd ska du på akuten kunna ge svar på alla grundläggande frågor som du, din patient eller den anhörige kan ha avseende en specifik ortopedisk skada. Redan i det första mötet ska du kunna redogöra för utredning, behandling, eftervård och eventuella komplikationer. Traumaortopedi vänder sig till läkare som möter traumapatienter – på ortopeden, akuten, bakjouren eller på röntgen vid klassificering av skador. Fysioterapeuter, arbetsterapeuter och alla andra som är delaktiga i den ortopediska traumavården kan också ha stor nytta av boken.

According to Jon Karlsson, the influence of genetic factors on human mentality has been neglected for many years in the study of intelligence. He contends that the evidence for biological influences on human intelligence is too compelling to be ignored any longer. Karlsson believes that such influences can be positive, and that ways can be found to measure their importance.Serious efforts are necessary to extend the scope of basic conceptions concerning the structure of the brain and to explore the mysteries of the physiological mechanisms that govern the human mind. The research reported in this volume suggests some approaches that might prove useful. Karlsson believes that an effective approach to the genetics of mentality can be built around studies of serious brain abnormalities. Beginning with the idea that psychosis probably has a genetic bond to creativity, he argues that parallel possibilities exist in relation to other frequently occurring disorders. The product of many years of research, this work is certain to be a source of both controversy and of new ideas for the study of human intellectual development.

This fully updated and integrated edition of Sports Injuries: Prevention, Diagnosis, Treatment and Rehabilitation covers the whole field of sports injuries and is an up-to-date guide for the diagnosis and treatment of the full range of sports injuries. The work evaluates sports injuries of each part of the musculoskeletal system paying detailed attention to four main aspects: prevention, diagnosis, treatment and rehabilitation. More than 300 world-renowned experts critically present the emerging treatment role of current strategies combining evidence-based data and clinical experience. In addition, pediatric sports injuries, extreme sports injuries, the role of physiotherapy, and future developments are extensively discussed. Lastly the work explores the effects of the COVID-19 pandemics on several aspects of sports injuries, e.g. epidemiology, prevention, management strategies as well as its psychosocial impact. All those who are involved in the care of patients with sports injuries will find this book to be an invaluable, comprehensive, and up-to-date reference.

Filling a gap in literature, this book examines surgical trials with a special focus on the underlying principles, challenges, and best practices to successfully conduct rigorous surgical research.While randomized controlled trials (RCTs) remain the gold standard for evaluation of the safety and efficacy of most medical interventions, they are particularly difficult to implement successfully in the context of surgery. As a result, recruitment rates are often extremely low, crossover from non-operative to operative is common, and patients randomly allocated to surgery often simply decline to have the procedure. All of these challenges call into question the recent generalizability and fundamental quality of traditional surgical RCTs. As such, this book explores advanced alternative trial design methods and describes the current regulatory environment around the world. Designed as a practical guide, it is a valuable tool for surgeons, epidemiologist and biostatisticians involved in this challenging field.
