Nyaya yekusarudza ukobvu hwembambo dzemukati memedullary dzemapfupa marefu emakumbo epasi.

Kurovera mapfupa mukati memudumbu ndiyo nzira yakanakisisa yekurapa kutyoka kwemapfupa emudumbu ari mudumbu rezasi. Izvi zvinopa mabhenefiti akadai sekukuvara kushoma uye simba guru re biomechanical, zvichiita kuti zvinyanye kushandiswa pakutyoka kwe tibial, femoral, uye humeral shaft. Mukurapa, kusarudzwa kwedhayamita ye intramedullary nail kunowanzo batsira nzara yakakora inogona kuiswa ne reaming iri pakati nepakati, kuti ive nechokwadi chekugadzikana kukuru. Zvisinei, kana ukobvu hwe intramedullary nail huchikanganisa zvakananga fungidziro yekutyoka hazvisati zvanyatsojeka.

Muchinyorwa chakapfuura, takakurukura nezvechidzidzo chaiongorora kukanganiswa kwedhayamita yenzimbo dzemukati memedullary pakupora kwemapfupa muvarwere vane makore anopfuura makumi mashanu vane kutyoka kwemukati metrochanteric. Zvakabuda hazvina kuratidza mutsauko wehuwandu hwekupora kwetsinga uye huwandu hwekuvhiyiwazve pakati peboka re10mm neboka rine nzara dzakakora kupfuura 10mm.

Pepa rakaburitswa muna 2022 nenyanzvi dzeTaiwan Province rakasvikawo pamhedziso yakafanana:

Ongororo yakaitwa nevarwere 257, avo vakagadziriswa nzara dzemukati memedullary dzine dhayamita ye10mm, 11mm, 12mm, uye 13mm, yakapatsanura varwere mumapoka mana zvichienderana nedhayamita yenzara. Zvakaonekwa kuti pakanga pasina musiyano wehuwandu hwekupora kwetsandanyama pakati pemapoka mana.

Saka, izvi ndizvo zviri kuitikawo here pakutyoka kwemubato wetibial?

Muchidzidzo chekuongorora nyaya chaisanganisira varwere makumi matanhatu, vaongorori vakapatsanura varwere makumi matanhatu zvakaenzana kuita mapoka maviri e30 rimwe nerimwe. Boka A rakagadziriswa nenzara dzakatetepa dzemukati medullary (9mm yevakadzi uye 10mm yevarume), ukuwo Boka B rakagadziriswa nenzara dzakakora dzemukati medullary (11mm yevakadzi uye 12mm yevarume):

Zvakabuda zvakaratidza kuti pakanga pasina musiyano wakakura mumhedzisiro yekiriniki kana mifananidzo pakati penzara dzakatetepa nedzakakora dzemukati memedullary. Pamusoro pezvo, nzara dzakatetepa dzemukati memedullary dzaibatanidzwa nenguva pfupi yekuvhiyiwa uye fluoroscopy. Pasinei nekuti nzara yakakora here kana kuti yakatetepa yakashandiswa, kudzorwa kwemuviri zvine mwero kwakaitwa pamberi pekuiswa kwenzara. Vanyori vanoti kana paine kukuvara kuri nyore kwetibial shaft, nzara dzakatetepa dzemukati memedullary dzinogona kushandiswa kugadzirisa.
