Intramedullary mbiriIcho chinowanzoshandiswa erthopedic yemukati maitiro maitiro anodzokera kuma1940. Iyo inoshandiswa zvakanyanya mukurapa kwefudzi refu pfupa, dzisiri dzehukama, uye kumwe kukuvara kwakanangana. Nyanzvi inosanganisira yekuisa chipikiri chakapindirwa muCentral Canal yepfupa kuti ibvise nzvimbo yakatsemuka. Mumitemo yakapusa, iyo intramedullary mbichana chidimbu chakareba chine akawandaKuvhiya screwMakomba pamigumo miviri, ayo anoshandiswa kugadzirisa iyo proximal uye distal magumo ekupwanya. Zvichienderana nezvemukati yavo, intramedullary zvipikiri zvinogona kuunganidzwa seyakaoma, tubular, kana yakavhurika-chikamu, uye inoshandiswa kurapa mhando dzakasiyana dzevarwere. Semuenzaniso, zvipikiri zvakasimbiswa zvine simba zvine basa riri nani pakutapukira nekuda kwekushaikwa kwavo kwenzvimbo yekufa.
Ndedzipi mhando dzeFraces dzakakodzera zvipikiri zvemukati?
Intramedullary mbichanais a claption yakakodzera yekubata diffyseal fractures, kunyanya mu femur uye tibia. Kuburikidza nemitongero madiki ekupinda, intramuterllary chipikiri chinogona kupa kugadzikana kwakanaka uchideredza kukuvadza kwakapfava.
Iyo Yakavharwa Kudzikisira uye Intramedullary Kuvhiya Kugadziriswa Kuvhiya kune Zvinotevera Zvinotevera:
Kuvharwa kuderedzwa uye intrameduutery nailing (crin) kune zvakanakira kudzivisa chiitiko cheiyo inovhiringidza nzvimbo uye kuderedza njodzi yekutapukirwa. Iine chidimbu chidiki, chinodzivirira zvakapfava zvakapfava tissue dissuction uye kukuvadza kune ropa rekupa panzvimbo yakatsemuka, nekudaro ichivandudza huwandu hwekupora. Yemhando dzechokwadi dzeProximal Bone Fractures, Crc inogona kupa kugadzikana kwekutanga kwekutanga, kubvumira varwere kuti vatange kubatanidza kutanga; Izvo zvakare zvinoshandisawo maererano nekubereka kusagadzikana kwesimba kana uchienzaniswa nedzimwe nzira dzekugadzirisa eccentric maererano ne biomechanics. Zvinogona kudzivisa kusasunungura kwekugadziriswa kwemukati mushure mekuvhiyiwa nekuwedzera nzvimbo yekuonana pakati pePlant uye pfupa, zvichiita kuti ive yakakodzera kune varwere vane osteoporosis.
Kuiswa kuTibia:
Sezvinoratidzwa muchimiro, maitiro ekuvhiya anosanganisira kugadzira chidimbu che3-5 cm chete pamusoro pe tibial tubercle, uye kuisa 2-3 inokiya zvibodzwa zvisingasviki 1 cm proximal uye distal magumo egumbo rezasi. Kuenzaniswa neyechinyakare kuvhurika kuderedzwa uye kugadziriswa kwemukati nedanda resimbi, izvi zvinogona kunzi nyatso kusimbisa maitiro ekusangana.
Zvinoshandiswa kune femur:
1.Interlocking basa rechikadzi rakakiiwa intramedudullary mbambo:
Inoreva kugona kwayo kuramba kutenderera kuburikidza nekuvhara muchimiro cheiyo intramedullary mbambo.
2.classudzika yeiyo yakakiiwa intramedullary mbambo:
Panyaya yebasa: Standard yakavharwa intramedullary chipikiri uye kuvakwazve yakavharwa intramedudullary mbambo; Kunyanya kutsanangurwa nekushushikana kwekutapurirana kubva kuhudyu pakati pebvi, uye kana iyo yepamusoro uye yakadzika zvikamu pakati pevaima (mukati me5cm) yakagadzikana. Kana isina kugadzikana, kuvakwazve kwehurumo kushushikana kunodiwa.
Panyaya yehurefu: pfupi, proximal, uye yakawedzera mhando, kunyanya yakasarudzwa zvichienderana nekureba kweiyo inopwanya nzvimbo kana ichisarudza kureba kweiyo intramedeny chipikiri.
2.1 standard inobvumika intramedullary zvipikiri
Basa guru: Axial kushushikana kushushikana.
Zviratidzo: Fractures yeiyo feokh shaft (isingashande kune subtrochantt mafungidziro)
2.2 Kuvakazve kukanganisika intramedullary mbambo
Basa guru: Iko kushushikana kwekutapurirana kubva muhudyu kune shaft yemukadzi haina kugadzikana, uye kugadzikana kwekushushikana kwekutapurirana muchikamu ichi chinoda kuvakwa.
Zviratidzo: 1. Subtrochanttic fractures; 2..
PFN iyi zvakare mhando yekuvakazve-mhando intramedudullary chipikiri!
2.3 Distal Locking Mechanism yeIntramedullary Chikamambo
Iyo Distal Locking Methinism yemukati menyeti zvipikiri zvinosiyana zvichienderana nemugadziri. Kazhinji, imwe chete scirecing screck inoshandiswa proximal femored Zvese zvechikadzi uye tibial zvakachinjika zvipikiri zvakarongedzwa zvine maviri anokiya zviyero.
