Description
Vynález se týká úplných nebo částečných náhrad dlouhých kostí v lidském nebo živočišném organismu.
Dosavadní stav techniky
V případě, že dojde k vážnému poškození končetin nebo k tomu, že je nutno odstranit chirurgicky velkou část kosti, například v případě zhoubných kostních nádorů, je zapotřebí nahradit velkou část přirozené kosti. V těchto případech musí chirurg splnit celou řadu podmínek. K usnadnění takových zákroků si vynález klade za úkol navrhnout modulární systém, který tyto podmínky splňuje. Jedním z typických požadavků je například náhrada proximální nebo distální části stehenní kosti, popřípadě náhrada celé této kostí.
Podstata vynálezu
Podstatu vynálezu tvoří úplná nebo částečná náhrada dlouhé kosti u člověka nebo jiných živočichů. Tato náhrada obsahuje proximální nebo distální koncovou část, tvořící jednu ze složek nahrazovaného kloubu, tělo, spojené s distálním nebo proximálním koncem a stopku pro zasazení do zbývající kosti, přičemž tělo, stopka a distální nebo proximální konec jsou spolu spojeny matricovým a patricovým zkosením, přičemž každé patricové zkosení je opatřeno výběžkem, zasahujícím v podélném směru do náhrady mimo její osu do odpovídajícího vyhloubení matricového zkosení, mimoto obsahuje náhrada příčné otvory pro přístup ke • · · ·
koncové oblasti patricového zkosení nástrojem, sloužícím k oddělení jednotlivých částí, mimoto výběžek udržuje části náhrady v požadovaném úhlu spojení.
Náhrada podle vynálezu také obsahuje límec, který může být spojen s tělem nebo jeho prodloužením a který má takové rozměry, aby se mohl opřít o zbytek kosti, do níž má být náhrada zasazena, límec je opatřen částí, která je povrchově zpracována tak, aby kost mohla snadno prorůstat strukturovaným povrchem tohoto límce.
V případě, že má jít o náhradu proximálního konce stehenní kosti, obsahuje tato náhrada s výhodou trochanterovou část, spojenou s tělem náhrady a s její stopkou, přičemž trochanterová část má tvar, který přibližně odpovídá anatomickému trochanteru včetně krčku stehenní kosti, na němž je uložena kulovitá část stehenní kosti a včetně plochy na druhé straně krčku pro spojení ze zbytkem kosti nebo s měkkými tkáněmi.
Praktické provedení vynálezu bude osvětleno v souvislosti s přiloženými výkresy.

Na obr. 7 je znázorněno několik pohledů na modulární prodloužení těla náhrady podle vynálezu.
Příklady provedení vynálezu
Na obr. 1 je schematicky znázorněna sestavená náhrada pro proximální část stehenní kosti. Tato náhrada je tvořena trochanterovou částí 1 s krčkem 2, který je zkosen pro nasazení kulovité hlavice kloubu běžným způsobem.
Trochanterová část 1_ je podrobněji znázorněna v různých pohledech na obr. 3. Je možno pozorovat, že přibližně odpovídá anatomickému tvaru této části kosti a je opatřena plochou 2 Pro spojení se zbytkem kosti nebo s měkkými tkáněmi. Trochanterová část 1. má vnitřní matricové zkosení, jak je zřejmé z obr. 3 a je spojená s patricovým zkosením těla 5_. Podrobná konstrukce těla 5 je zřejmá z obr. 4, kde je zřejmé, že tělo 5 je opatřeno patricovým zkosením 33 na jednom konci pro spojení s matricovým zkosením trochanterová části 1. a na svém druhém konci je opatřeno matricovým zkosením í_ pro spojení s jedním koncem stopky 8, která je podrobněji znázorněna na obr. 5.
Stopka 3 je upevněna do zbytku stehenní kosti 9_ vtlačením nebo použitím kostního cementu. Distální konec těla 5 je obklopen límcem 10, který je podrobněji znázorněn na obr. 6. Límec 10 má distální dolní konec 11, který se opírá o zbytek odstraněné kosti, který je tvořen v tomto případě zbytkem stehenní kosti 9. Rozměry límce 10 se volí tak, aby koncová plocha límce 10 končila v souladu se zevním okrajem kosti 9. Límec 10 je na své zevní ploše opatřen výstupky nebo materiálem, podporujícím růst kosti, například hydroxyapatitem. Tímto způsobem je podporován růst kosti přes povrch límce 10, čímž dochází k dokonalejšímu upevnění náhrady v kosti 9.
V případě odstranění poškozené kosti nebo kostního nádoru je často možné zachovat zbytek 12 trochanteru. Tento zbytek 12 může obsahovat vazy nebo jinou měkkou tkáň, která může napomoci k upevnění trochanterové části 1. Zbytek 12 může být k trochanterové části 1 upevněn pomocí destičky 13, která se spojí s plochou 2 trochanterové části 3..
Na obr. 2 je znázorněn pohled na sestavenou náhradu distální části femuru, která obsahuje kondilární hlavovou část 21, tvořící horní část kolenního kloubu. Tato hlavová část 21 je spojená s tělem 5_ analogickým způsobem, jakým je s tělem 5 na obr. 1 spojena trochanterová část jL. Obdobným způsobem je spojeno tělo _5 se stopkou / a límcem 10, který zakrývá zkosenou dolní část těla 5, tak jak bylo svrchu popsáno v souvislosti s obr. 1. Dolní zkosený konec 11 těla 5 se opírá o zbývající plochu stehenní kosti 9. Obdobným způsobem je také upravena vnější plocha límce 10 pro podporu prorůstání nové kosti.
Podrobnosti trochanterové části 1 jsou zřejmé z • · • · obr. 3. Plocha 3_ trochanterové části 1 je opatřena hroty 30. Tyto hroty 30 zajišťují pevné spojení se zbytkem 12 kosti, jak je znázorněno také na obr. 1 a slouží k dokonalejšímu upevnění náhrady. Trochanterová část jl je opatřena matricovým vnitřním zkosením s vyhloubením 31. Vyhloubení 31 odpovídá svým tvarem výběžku 32 na patricovém zkosení 33 těla Ej, jak je také zřejmé z obr. 4. Trochanterová část 1_ je rovněž opatřena příčným otvorem 34, do nějž je možno zasunout nástroj pro oddělení jednotlivých částic náhrady v případě potřeby. Jak je zřejmé z obr. 4, je tělo E5 rovněž opatřeno matricovým zkosením Ί_ s vyhloubením 35, obdobným vyhloubení 31 v trochanterové části 1. Také tělo 5 je opatřeno příčným otvorem 36, do nějž je možno zasunout nástroj pro oddělení těla 5. a stopky 8. od sebe.
Jak je zřejmé z obr. 3, je trochanterová část 1 také opatřena příčnými otvory 36. Tyto otvory jsou určeny pro přišití trochanterové částí k měkkým tkáním, například ke šlachám v případě, že není k dispozici zbývající kost, která by mohla být upevněna k ploše 3.
Trochanterová část _1 tvoří standardní složku modulárního systému, i když je nutno ji provést v pravém a levém provedení. V některých případech je zapotřebí trochanterovou složku 1 upravit zejména v oblasti krčku pro potřeby jednotlivých nemocných.
Jak je znázorněno na obr. 4, je tělo 5_ dodáváno v různých délkách v intervalech 15 mm, přestože je jinak standardizováno, pokud jde o jeho zkosené části. Mimoto je tělo 5 opatřeno zářezy 37, do nichž zapadají odpovídající výstupky 38, provedené integrálně s límcem 10. Jak je ·· ··· · znázorněno na obr. 6, límec 10 je opatřen vnitřním zkosením 39, které odpovídá zkosení 40 na jednom konci těla 5. Spojení límce 10 s tělem a také výstupku 38 se zářezy 3 7 zajišťuje upevnění límce 10 bezpečně na těle Ej. Jak je zřejmé z obr. 6, je límec 10 dodáván v řadě průměrů Dl a D2 .
Na obr. 5 jsou znázorněny různé pohledy na stopku 8. Jak je zřejmé z .příčného řezu, je stopka vytvořena prostředky pro spojení s kostí, zejména s kostním kanálem a může být zcela přímá nebo zakřivená podle zakřivení tohoto kanálu. Proximální konec stopky 8 má zkosení 42, které odpovídá vnitřnímu matricovému zkosení Ί_ těla 5. Stopka _8 je rovněž opatřena výběžkem 43, který odpovídá vyhloubení 35 v těle 5. Tělo 5 je opatřeno příčným otvorem 36 pro zavedení nástroje pro oddělení těla 5 od stopky 8. Jak je zřejmé z obr. 5, může být stopka _8 dodávána v celé řadě průměrů a délek a může být přímá nebo zakřivená tak, aby vyhovovala různým chirurgickým požadavkům při upevňování náhrady do kosti.
Na obr. 7 je znázorněno modulární prodloužení těla _5, které umožňuje prodloužit celou náhradu, znázorněnou na obr. 1 a 2. Toto modulární prodloužení 50 je opatřeno matricovým zkosením 52 a patricovým zkosením 51 na svých opačných koncích. Tím odpovídá prodloužení 50 svým tvarem matricovému zkosení Ί_ těla 5. a zkosení 42 stopky 8_. Modulární prodloužení 50 může být použito s běžným tělem 5 nebo samostatně ke spojení trochanterové části ý nebo hlavové části 21 se stopkou Í3.
I když takové provedení není podrobně znázorněno, že možno použít náhradu z obr. 1 a 2 tak, že je možno vynechat • · · ·· · • · ·· stopku 8 a límec 10 . Mimoto je možno analogickým způsobem vytvořené části použít k náhradě jiné dlouhé kosti, například kosti pažní.
Jak bylo popsáno svrchu, je možno části náhrady od sebe snadno oddělit pomocí nástroje, zavedeného do příčných otvorů 34, 36, například při revizi operačního pole.
Výhodným materiálem pro výrobu náhrady podle vynálezu je slitina titanu až na hlavu stehenní kosti, kde se s výhodou užije slitin kobaltu a chrómu nebo keramických materiálů.
