Chivharo chendiro chigadziriso chekutsemuka chine buri rine shinda.Kana sikuruu ine musoro wakarukwa ichipindirwa mugomba, ndiro inova (screw) angle fixation device.Kukiya (angle-stable) simbi ma plates anogona kuve ese ari maviri ekukiya neasina-kukiya screw maburi ekuti masiruuru akasiyana apinzwe mukati (anonziwo maconfusion steel plates).
1.Nhoroondo nebudiriro
Mahwendefa ekukiya akatanga kuunzwa angangoita makore makumi maviri apfuura kuti ashandiswe mukuvhiya musana uye maxillofacial.Mukupera kwema1980 nema1990, zvidzidzo zvekuyedza pamhando dzakasiyana dzemidziyo yekumisikidza yemukati yakaunza mahwendefa ekukiya mukurapa kwekutyoka.Iyi nzira yakachengeteka yekugadzirisa yakatanga kugadzirwa kudzivirira yakakura yakapfava tishu dissection.
Zvinhu zvakati wandei zvakasimudzira kushandiswa kwekiriniki kwendiro iyi, kusanganisira:
Chiitiko chekuputsika kwemaitiro chinoramba chichiwedzera sezvo mararamiro ehupenyu anovandudza kune varwere vane kukuvara kwepamusoro-simba uye nhamba yevarwere vakwegura vane osteoporosis inowedzera muWestern Europe neNorth America.
Vanachiremba nevarwere havagutsikani nemigumisiro yemishonga kune dzimwe periarticular fractures.
Zvimwe zvisiri zvekiriniki zvinosimudzira zvinhu zvinogona kusanganisira: indasitiri yekusimudzira tekinoroji nyowani uye misika mitsva;kufarirwa zvishoma nezvishoma kwekuvhiyiwa kushoma, nezvimwe.
2.Unhu uye yakagadziriswa nheyo
Musiyano mukuru webiomechanical pakati pekukiya mahwendefa uye echinyakare mahwendefa ndeyekuti iyo yekupedzisira inotsamira pakukweshana pabhonzo-plate interface kupedzisa kudzvanywa kwebhonzo nendiro.
Iyo biomechanical hurema hwechinyakare simbi mahwendefa: compress iyo periosteum uye inokanganisa kubuda kweropa kusvika kumagumo ekutyoka.Naizvozvo, chinyakare chakasimba chakamisikidzwa plate osteosynthesis (senge interfragmentary compression uye lag screws) ine mwero wakanyanya kuoma, kusanganisira kutapukirwa, kuputsika kweplate, kunonoka kubatana, uye kusabatanidzwa.
Sezvo kutenderera kweaxial kunowedzera, screws dzinotanga kusunungura uye kuita kuti kukwesha kuderedze, pakupedzisira zvichiita kuti ndiro isununguke.Kana ndiro yacho ikasunungura kutsemuka kusati kwapora, kupera kwekuputsika kunenge kusina kugadzikana uye pakupedzisira ndiro ichaputsika.Kunyanya kuoma kuwana nekuchengetedza firm screw fixation (yakadai se metaphysis uye osteoporotic bone ends), zvakanyanya kuoma kuchengetedza kugadzikana kwekuguma kwekuputsika.
Fixed principle:
Kukiya mahwendefa haavimbe nekukweshana pakati pebhonzo-plate interface.Kugadzikana kunochengetedzwa neangularly stable interface pakati pe screw nesimbi ndiro.Nekuti iyi mhando yekuvhara yemukati inogadzirisa ine yakagadzikana kutendeseka, iyo yekudhonza-kunze simba rekukiya musoro screw yakakwira zvakanyanya kupfuura yeyakajairika screws.Kunze kwekunge ma screws ese akatenderedza adhonzwa kana kutyoka, zvinonetsa kuti screw iburitswe kana kutyoka yega.
3.Zviratidzo
Mazhinji akavhiyiwa mafractures haadi kukiya ndiro kugadzirisa.Chero bedzi nheyo dzekuvhiyiwa kwemapfupa dzichiteverwa, kuputsika kwakawanda kunogona kuporeswa nemahwendefa echinyakare kana intramedullary misumari.
Nekudaro, kune zvechokwadi mamwe akakosha marudzi ekutyoka ayo anowanzo kurasikirwa nekudzikisira, ndiro kana screw breakage, uye inotevera bhonzo nonunion.Mhando idzi, dzinowanzonzi "zvisina kugadziriswa" kana "dambudziko" kuputsika, zvinosanganisira intra-articular comminuted fractures, periarticular short bone fractures, uye osteoporotic fractures.Kuputsika kwakadaro zviratidzo zvekuvhara mahwendefa.
4.Kushandisa
Nhamba inowedzera yevagadziri vari kupawo mahwendefa eanatomical ane maburi ekukiya.Semuyenzaniso, preshaped anatomic plates for the proximal and distal femurs, proximal uye distal tibias, proximal uye distal humerus, uye calcaneus.Iyo dhizaini yeplate yesimbi inoderedza zvakanyanya kusangana pakati pesimbi ndiro uye bhonzo muzviitiko zvakawanda, nekudaro kuchengetedza periosteal ropa rekupa uye perfusion yekuputsika kupera.
LCP (kukiya compression plate)
Iyo yekuvandudza yekuvhara yekumanikidza ndiro inosanganisa maviri akasiyana zvachose emukati ekugadzirisa matekinoroji mune imwe implant.
LCP inogona kushandiswa sendiro yekumanikidza, yekukiya yemukati bracket, kana musanganiswa wezviviri
Minimally invasive:
Nhamba inowedzera yekuvhara mahwendefa ane ekunze stent zvibato, zvibatiso, uye blunt tip magadzirirwo anobvumira varapi kuisa ndiro iyo submuscularly kana subcutaneously nekuda kwezvishoma zvinopinda.
