Unoziva here nhoroondo ye intramedullary nailing?

Kuuya kwe intramedullary nail kwakashandura kurapwa kwemafupa marefu akatyoka. Kunyangwe hunyanzvi hwacho hwaivepo kwemazana emakore, hahuna kuwana chimiro chayo chazvino kusvika muhafu yechipiri yezana ramakore rechi20.

Nzira yekubudirira yakanga isiri nyore nguva dzose, sezvo nzira yacho yakasangana nekusava nechokwadi uye kurambwa nenyanzvi dzakawanda muhafu yekutanga yezana remakore rechi20. Nhasi, kuburikidza nekuvandudzwa kwesimbi, maitiro ekuvhiya uye hunyanzvi hwefluoroscopic, intramedullary nailing yave chiyero chekutarisira kwekutyoka kwepfupa refu.

Kufambira mberi muruzivo rwevanhu biomechanical kwakaita kuti kusikwa kweiyi dhizaini yemazuva ano kugoneke. Mazuvano intramedullary nailing inoratidzwa nekuderera kwehutachiwana hwehutachiona, kushoma mavanga, kugadzikana kwakanaka kwekutyoka, uye kufamba kwemurwere nekukurumidza.

Ongororo yezvakaitika kare yakaitwa munyaya ino ine chinangwa chekupfupisa kushanduka kwechipikiri che intramedullary, kusimbisa zviitiko zvayo zvinokosha, kuratidza nguva yemhepo yekushandiswa kwekutanga uye kushanduka kunotevera kwechipikiri che intramedullary, uye kuunza nzvimbo ye intramedullary mbambo mune zvemazuva ano orthopedics uye traumatology (semuenzaniso, Mufananidzo 1).

Kuberekwa kwe intramedullary nail

MaEgipita ekare akatanga kushandisa intramedullary mudziyo wakafanana nembambo. Complex yekuvhiya kutyoka kutarisirwa kwaisaita kunge kwavepo makore mazhinji apfuura.

Chine chokwadi, zvisinei, ndechekuti vaEgipita vekare vaive nehunyanzvi hwekuomesa zvitunha hwaibva mukutenda kwavo mukumuka kwemuviri muhupenyu hwapashure perufu.

Izvi ndizvo zvakaitika naamai vanonzi Usermontu vakawanikwa muguva raTutankhamun, apo mbambo yakarukwa yakaiswa pakati pefemu netibia kuti igadzikane ibvi rekubatana (semufananidzo 2).

Vanochera matongo vanofungidzira kuti mummy mukati me sarcophagus akanga asiri Usermontu pachake, asi mumwe munhu akatsiviwa nemakororo ekare eguva muna 600 BCE.

Makore 2000 gare gare, Bernardino de Sahagun, anthropologist paHernando Cortes expedition, akashuma kushandiswa kwekutanga kwe intramedullary nailing mumurwere mupenyu muMexico.

Muna 1524, akaona chiremba weAztec bone (anonzi 'Tezalo') achiita osteotomy achishandisa banga re obsidian uye oisa tsvimbo yeresin mumedullary cavity kuti agadzikane kuputsika. Nekuda kwekushaikwa kwehunyanzvi hwekuvhiya hwakakwana uye mishonga inouraya hutachiona, maitiro aya aive nehuwandu hwekunetsekana uye huwandu hwekufa kwakanyanya.

1800s: Matanho ekutanga

Pakati pemakore ekuma1800, magazini ekutanga ezvokurapa akashuma nezve intramedullary nailing. Diefenbach, Langenbeck, Bardenheuer nevamwe vanachiremba vanotaura chiGermany vanonzi vakashandisa zvipikiri zvenyanga dzenzou mumwongo wemapfupa akareba kuti vabate kuparara kwemapfupa.

Zvichakadaro, Nicholas Senn wekuChicago, muongorori uye anovhiya muchiuto anovhiya, akaita ongororo ne intramedullary fixation. Aizoshandisa buri rakapinza rakagadzirwa nebovine bhonzo oriisa mu medulla kurapa 'pseudarthrosis' mushure mekutyoka.

Muna 1886, Heinrich Bircher wekuSwitzerland akatsanangura pamusangano wekuvhiya kuiswa kwezvipikiri zvenzou mu medulla kuitira kurapwa kwakanyanya kwekuputsika kwakaoma (Mufananidzo 3).

Makore mashoma gare gare, Themistocles Gluck muGermany akagadzira mbambo yekutanga yenzou intramedullary ine gomba pamagumo embambo, nokudaro achiunza pfungwa yekubatanidza kekutanga.

Munguva imwe cheteyo, Julius Nicolaysen wekuNorway ndiye akatanga kunyora nezve biomechanical nheyo dze intramedullary nailing ye proximal femoral fractures. Akasimbisa kukosha kwekuwedzera kureba kwembambo ye intramedullary kuti uwane hukuru hwe biomechanical uye kupa kudzivirirwa kweinenge pfupa rose.

Akanga ariwo wekutanga kupa pfungwa yeproximal uye distal mbambo / bone interlocking kugadzira static kukiya. Anoonekwa nedzimwe nyanzvi sababa ve intramedullary nailing.

Pakazosvika pakati pemakore ekuma1800, mapiyona akadai saIgnaz Philipp Semmelweis kuVienna naJosephLister kuGlasgow vakanga vavaka hwaro hwekuvhiya mbereko. Uku kwaive budiriro huru nekuti yakabvumira kuvandudzwa kwemaitiro matsva ekuvhiya pasi pemamiriro eeseptic.

1900s: Evolution

Muna 1912, chiremba wokuvhiya wekuBritain Ernest Hay Groves ndiye aive chiremba wekutanga kushandisa simbi yakasimba sembambo yemukati medullary uye aive piyona weiyo retrograde intramedullary chipikiri.

Akawana ruzivo rwake munguva yeHondo Yenyika I apo akarapa varwere vane utachiona hwepseudarthrosis vakanga vasingadi kudimbura makumbo nemaoko. Haana kungotsanangura nzira yekutanga ye intramedullary nailing yakabvumira osseointegration kuburikidza nekushungurudzika kuduku, asi aivewo neunyanzvi hwekushandisa intramedullary misumari uye zvipikiri zviduku kugadzirisa kuputsika.

Akaedza ma implants akagadzirwa nealuminium, magnesium nesimbi uye akaziva kukosha kwebiomechanics mukurapa kwekutyoka. Kunyangwe zvakadaro, maitiro aErnest Hay Groves akatambura nehuwandu hwehutachiona uye saka akange asina kufarirwa zvakanyanya nevenguva yake.

Muna 1931, Smith-Petersen, chiremba wekuAmerica wemapfupa, akaunza siruu yesimbi ine mapapiro matatu yekurapa intra-articular capsule femoral neck fractures. Akagadzira nzira yakazaruka yakapinza anterior chetatu cheiriac crest, yakapinda mumunda wekushanda ichitevedza kumucheto kweanterior fascial tensor, ndokuisazve pakatyoka uye akashandisa impactor kutyaira simbi isina tsvina mumusoro wechikadzi (Figure 4).

Nekuda kwekubudirira kwekutongwa kweSmith-Petersen, vanachiremba vazhinji vakatanga kuedza nesimbi inodyarwa yekutyoka. Sven Johansson akagadzira hollow intramedullary chipikiri muna 1932; hungwaru hwake hutsva hwakashandisa tsono yekerfing yaibvumira kudzorwa neradiologically guided kuiswa kwe intramedullary chipikiri. Zvinhu zvakakosha zvehunyanzvi zvaakashandisa zvichiri kushandiswa nanhasi.

Vachienda nhanho imwe mberi, Rush nemukoma wake vakaunza pfungwa ye elastic intramedullary chipikiri muna 1937.

Vakashandisa elastic, pre-yakabhenda Stainless simbi intramedullary chipikiri uye vakaedza kugadzira intramedullary matatu-point fixation chimiro kurwisa tsika yeaxial displacement yakatenderedza kuputsika.

Mune pfungwa yavo, iyo yakapfava yakapfava nzvimbo inoita senge bhendi rekumanikidza rinopokana netension inogadzirwa ne-pre-bent elastic nail. Kuvakwa kwavo kwaiganhurirwa neiyo elastic properties yesimbi isina tsvina, iyo yakachinja kare kubva kugomba deformation kuenda kupurasitiki deformation. Iyo yekupedzisira inogona kutungamira kune yechipiri kutamiswa uye kuremara kuporeswa.

Pamusoro pezvo, zvipikiri zve intramedullary zvinowanzobuda pamusuwo kana kupinda mukati mezvivakwa zvemabhonzo, kana kutopinda mukati mejoinhi. Zvakadaro, nyanzvi yeViennese Ender yakaramba ichishandisa nzira iyi sehwaro hweEnder chikoro chekugadzirisa kuputsika uye ichiri kushandiswa nanhasi kugadzirisa kuchinjika kwekutyoka kwevana.

Mwongo mbambo

Muna 1939, chiremba wokuvhiya wekuGermany Gerhard Küntscher, akasarudzwa Mubairo weNobel, akagadzira chipikiri chesimbi isina tsvina chemukati medullary chekurapa kwekutyoka kwedzinde remukadzi.

Küntscher nevamwe vakafemerwa neSmith-Petersen Stainless steel screws anoshandiswa kurapa tyoka mutsipa wemukadzi uye vaidavira kuti misimboti imwe cheteyo yaigona kushandiswa pakutyoka. Iyo intramedullary chipikiri yavakagadzira pakutanga yaive V-yakaita muchinjika-chikamu uye 7-10 mm mudhayamita.

Mushure mezvidzidzo zvecadaveric nemhuka, akapa intramedullary mbambo uye nzira yekuvhiya pamusangano wekuvhiya muBerlin muna 1940. Pakutanga, hutsva hwake hwakasekwa nevamwe vake veGermany, kunyange zvazvo nzira yake yakawana mukurumbira mushure meHondo Yenyika II.

Hippocrates (460-370 BC), chiremba wekare wechiGiriki aigara achinzi baba vemishonga, akamboti, 'Uyo anoda kuvhiya anofanira kuenda kuhondo'; zvimwe chetezvo ndizvo zvakanga zvakaita Küntscher.

Munguva yevaNazi, Küntscher aigara muchipatara chiri pamberi peFinland. Ikoko, akakwanisa kuvhiya varwere nevasungwa vehondo munharaunda yacho. Akasuma mwongo nailing pfungwa achishandisa yakavharwa uye yakavhurika nzira yekuvhiya, zvichiteerana.

Munzira yakavharwa, akapfuudza chipikiri che intramedullary munzira yekusimudzira kuburikidza netrochanter yakakura ndokuiisa patafura yekudzosa yakashandiswa nechipfuramabwe. Kutyoka kunoiswazve uye chipikiri chinopinzwa mundege mbiri uchishandisa musoro fluoroscopy. Munzira yakazaruka, mbambo ye intramedullary inopindirwa kuburikidza nekuputsika mukati me medulla kuburikidza necheka pedyo nemutsara wekuputsika.Küntscher anoshandisa intramedullary nail kurapa femoral stem fractures pamwe netibial uye humeral fractures.

Magadzirirwo akaitwa naKüntscher akasvika pakuzivikanwa pasi rese mushure mekudzoserwa kumusha kwevasungwa vehondo veAllied.

Nenzira iyi vanachiremba vekuAmerica neBritain vakajairana nembambo ye intramedullary yakagadzirwa naKüntscher uye vakaziva zvakanakira zvayakanakira munguva ino yekurapa kwekutyoka.

Mukati menguva pfupi, vanachiremba vokuvhiya vakawanda munyika yose vakatanga kushandisa nzira yake, uye chipikiri chemukati memuviri chaKüntscher chakachinja kurapwa kwekutyoka nokuderedza nguva yokupora kwomurwere nerinenge gore. Varwere vaizofanira kuvharwa mucast kwemwedzi yakawanda zvino vaigona kufamba mumazuva mashoma.

Parizvino, chiremba wekuvhiya weGerman anoonekwa semugadziri akakosha weiyo intramedullary chipikiri, uye ane nzvimbo yakakosha munhoroondo yekuvhiyiwa kwekukuvara.

Kuwedzera Intramedullary Nail

Muna 1942, Fisher et al. akatanga akatsanangura kushandiswa kwemarrow-kuwedzera grinding drill kuwedzera nzvimbo yekubatana pakati pe intramedullary nail uye pfupa uye kuvandudza kugadzikana kwekugadzirisa kuputsika.

Zvakadaro, Küntscher yakaunza flexible-guided reming drill iyo ichiri kushandiswa nanhasi uye inotsigira reming pamusoro pehurefu hwose hwemedullary cavity yebhonzo rebhonzo kufambisa kuiswa kwehombe dhayamita intramedullary zvipikiri.

Pakutanga, intramedullary reming yakagadzirirwa kuwedzera zvakanyanya nzvimbo yepfupa yekubatana ne intramedullary mbambo yekugadzirisa kugadzikana kwekuputsika uye kukurumidza kufamba kwevarwere.

Sezvakatsanangurwa naSmith et al, yega yega 1 mm yekuwedzera kwemedullary inowedzera nzvimbo yekusangana ne38%. Izvi zvinobvumira kushandiswa kwezvipikiri zvakakura uye zvakasimba zve intramedullary, zvichisimbisa kugadzikana kwese kwechimiro chekugadzirisa kuputsika.

Zvisineyi, kunyangwe mbambo yeKüntscher intramedullary ine flexible intramedullary reaming drill yakave sarudzo yakakodzera yemukati mekugadzirisa mudziyo weosteotomy, academia yakarasa kufarirwa nayo mukupera kwema1960 ichifarira mahwendefa matsva eArbeitsgemeinschaft für Osteosynthesefragen (A).

1960s: Nguva yeRima

Mumakore ekuma1960, kurovera zvipikiri kwemukati medullary kwakangoerekana kwabviswa nekuda kwekugadziriswa kweplate uye screw fracture.

Kunyange zvazvo nzira yaKüntscher yaishanda zvakanaka, vanachiremba vokuvhiya pasi pose vakairamba nemhaka yemigumisiro yakaipa yapashure pokuvhiyiwa.

Mukuwedzera, vamwe vavhiyi vakatanga kusiya nzira dzokushandisa mwaranzi, dzakadai se<em>fluoroscopy yemusoro, nokuti vanachiremba vokuvhiya vakatanga kusemeswa nemigumisiro yakaipa inobatanidzwa nemwaranzi. Kuvandudzwa kwe intramedullary nailing hakuna kumira ipapo, pasinei nekubvumirana kwenyika dzakawanda kushandiswa kweplate internal fixation systems.

Küntscher, chiremba wekuGermany, akaziva zvakanakira kuvharika uye akagadzira chipikiri chemukati memudumbu chakaita sevhavha, icho akachitumidza kuti 'chipikiri chekuvharirwa'. Iyo Achilles chitsitsinho che intramedullary chipikiri dhizaini yenguva iyoyo yaive kusakwanisa kudzikamisa zvakanyanya comminuted fractures kana fractures dzakatamiswa mumakona makuru Mhinduro yedambudziko iri yaive kushandiswa kwekuvhara screws.

Mhinduro yedambudziko iri yaive yekudzikamisa intramedullary mbambo ine locking screw.

Neiyi nzira, iyo implant inogona kuramba iri nani kukotama uye torsional masimba uku ichidzivirira kupfupisa nhengo. Kuchishandisa musanganiswa wemazano kubva kuna Küntscher, Klaus Klemm, naWolf-Dieter Schellmann, chipikiri chemukati medullary chakagadzirwa kuti chipe kugadzikana kukuru nekufanoboora maburi escuru proximal uye distal kune intramedullary chipikiri, icho chakavharirwa kune screw yakaiswa.

Mumakore mashomanana akatevera, kufambira mberi kwekujekesa kwechifananidzo chefluoroscopic kwakabvumira kusarudzwa zvakare kwekuvharwa kwekuputsika uye maitiro ekuderedza.

1970s uye 1980s: Rumutsiriro

Mumakore ekuma1970, kufarira pfungwa ye intramedullary nailing yachiremba wekuGermany Küntscher yakanga yakanyanya.

Yakavharwa kudzikisa intramedullary chipikiri kugadzirisa kwekutyoka, nekupindirana kwayo kweanochinjika reming uye kupindirana pfungwa uye kujekeswa kwakawedzera kujeka kwe fluoroscopic matekiniki, yakafambisa kufambira mberi uye kuparadzira iyi yakanakisa nzira yekuvhiya, inoratidzirwa nekushoma nyoro kukuvara kwenyama, kugadzikana kwakanaka, uye nekukurumidza kufamba kwemurwere.

Panguva iyoyo, nyika yezvidzidzo yakatsvairwa munhevedzano yezvitsva zvakafambisa kuvandudzwa kwechizvarwa chechipiri che intramedullary nailing.

Muna 1976, Grosse naKempf vakagadzira mbambo yemukati medullary kuti igadzirise dambudziko reiyo elastic modulus ye intramedullary chipikiri. Iyo intramedullary mbambo yakanga isina kutsvetwa munharaunda yeproximal uye yaive neburi rembambo yeproximal screw, iyo yakaiswa pa45-degree angle kuti iwedzere kugadzikana kwesimba re intramedullary chipikiri mukati mekugadzirisa chimiro.

Makore mashoma gare gare, AO yakabatana neiyo intramedullary mbambo yekuvandudza zvipikiri nekugadzira zvakafanana mimba intramedullary mbambo (Mufananidzo 5)

Muna 1984, Weinquist et al. yakakurudzira nzira ine simba, yaive yekusimudzira kuporeswa kwekupedzisira nekuisa maburi akakura ekukiya screw, kubvisa static yekuvhara screws, uye nekuzogadzirisa maburi ekukiya ekukiya kumaburi ezvipikiri mune imwe yazvino dhizaini.

Chinangwa chemaitiro ane simba ndechekusimudzira kuporeswa kwekutyoka uye kudzivirira pfupa kusabatana nekuda kwekunonoka kuita.

Parizvino, intramedullary nailing dynamics yakarasikirwa nevatsigiri vayo senzira yekumira-yega uye ikozvino inoshandiswa chete sechinhu chinodhura-chinogadzirisa pane kutsiva kwakakwana kwegadziriro yekugadzirisa mukati mukurapa kwekuputsika kusina kuporesa.

Muchidzidzo chebiomechanical, Gimeno et al. yakashuma kuti nzvimbo yekuchinja pakati pezvisina-slotted uye slotted zvikamu zve intramedullary mbambo zvakakonzera kushushikana kwekunetseka uye kukundikana kwekuvhiya kwemukati kugadzirisa kugadzirisa.

Kugadzirisa matambudziko aya, Russel naTaylor et al. yakagadzira yekutanga isina-slotted, isina-dilated intramedullary chipikiri muna 1986, ine mhedzisiro inogutsa.

Munguva iyi, dambudziko rekubatanidza zvipikiri zve intramedullary rakaramba richienderera mberi, uye sezvatinoziva nhasi, kupindirana ne screw kuburikidza ne intramedullary chipikiri pre-yakaboorwa gomba kwaiva dhizaini yeKlemm naSchleman kuGermany. Kuiswa kwe screw kwaizotungamirirwa ne freehand fluoroscopy, iyo yaizoisa pachena chiremba wekuvhiya kune yakawanda yemwaranzi.

Nhasi, dambudziko iri rakagadziriswa ne distal yakananga sisitimu iyo inosanganisira electromagnetic field tracking tekinoroji, fluoroscopically inotungamirwa freehand tekinoroji, uye chaiyo proximal chipikiri yekuisa gwara.

1990s: Titanium intramedullary chipikiri

Mumakore gumi akatevera, Russel-Taylor intramedullary nail yakave yakakurumbira zvikuru munharaunda yepasi rose yemapfupa. Chiyero chekuchengeta zvishoma nezvishoma chakave intramedullary chipikiri ne static kukiya kwe screws, sezvakaratidzwa nemhedzisiro yeongororo naBrumback et al.
