Kutyoka kwemutsipa wemukadzi kunokonzera 50% yekutyoka kwechiuno. Kune varwere vasiri vakwegura vane kutyoka kwemutsipa wemukadzi, kurapwa kwemukati kunowanzo kurudzirwa. Zvisinei, matambudziko epashure pekuvhiyiwa, akadai sekusabatana kwekutyoka kwemutsipa, kutyoka kwemusoro wemukadzi, uye kupfupika kwemutsipa wemukadzi, zvakajairika mukurapa. Parizvino, tsvakiridzo dzakawanda dzinotarisa pakudzivirira kutyoka kwemusoro wemukadzi mushure mekupfigwa kwemutsipa wemukadzi, nepo kutarisirwa kushoma kuri kupihwa panyaya yekupfupika kwemutsipa wemukadzi.
Parizvino, nzira dzekugadzirisa mutsipa wefemoral, kusanganisira kushandisa screws nhatu dzine cannulated, FNS (Femoral Neck System), uye dynamic hip screws, zvese zvine chinangwa chekudzivirira femoral neck varus uye kupa axial compression kudzivirira kusabatana. Zvisinei, kudzvanywa kusingadzoreki kana kwakanyanya kutsvedza kunotungamira mukupfupika kwemutsipa wefemoral. Tichifunga nezveizvi, nyanzvi dzeSecond People's Hospital Affiliated neFujian University of Traditional Chinese Medicine, dzichifunga nezvekukosha kwehurefu hwemutsipa wefemoral mukuporesa kutyoka uye kushanda kwechiuno, dzakakurudzira kushandiswa kwe "anti-shortening screw" pamwe chete neFNS yekugadzirisa kutyoka kwemutsipa wefemoral. Maitiro aya akaratidza mhedzisiro yakanaka, uye tsvakiridzo iyi yakaburitswa mumagazini yazvino yemagazini yeOrthopaedic Surgery.
Nyaya yacho inotaura nezvemhando mbiri dze"zvikuruu zvinodzivirira kupfupika": imwe iri screw yakajairwa ine kannu uye imwe screw ine dhizaini yetwo-thread. Pamakesi makumi mashanu nematatu ari muboka rezvikuruu zvinodzivirira kupfupika, makesi mana chete ndiwo akashandisa screw ine two-thread. Izvi zvinomutsa mubvunzo wekuti screw ine kannuu ine thread isina kunyanya thread ine simba rekudzivirira kupfupika.
Pakaongororwa masikuruu ese ari maviri ane shinda dzakatetepa pamwe chete nemasikuruu ane shinda mbiri pamwe chete zvichienzaniswa neFNS internal fixation yechinyakare, zvakabuda zvakaratidza kuti mwero wekupfupika muboka remasikuruu anodzivirira kupfupika waive wakaderera zvakanyanya pane muboka remasikuruu echinyakare eFNS panguva yekutevera kwemwedzi mumwe chete, mwedzi mitatu, uye gore rimwe chete, zvine kukosha kwehuwandu. Izvi zvinomutsa mubvunzo wekuti: Mhedzisiro yacho inokonzerwa nesikuruu yakajairwa ine shinda mbiri here kana kuti sikuruu ine shinda mbiri?
Nyaya iyi inopa nyaya shanu dzine chekuita ne screws dzinodzivirira kupfupika, uye kana zvanyatsoongororwa, zvinogona kuonekwa kuti muzviitiko 2 ne3, apo screws dzine tambo shoma dzakashandiswa, paive nekubviswa kwe screws uye kupfupika kwaionekwa (mifananidzo yakanyorwa nenhamba imwechete inoenderana ne screws imwe chete).
Zvichibva pamifananidzo yekesi, kushanda kwe screw ine tambo mbiri mukudzivirira kupfupika kuri pachena. Kana zviri zve screws dzakaiswa mu cannula, chinyorwa hachipe boka rekuenzanisa rakasiyana. Zvisinei, chinyorwa chinopa maonero akakosha pakugadzika kwemukati me femoral neck, zvichisimbisa kukosha kwekuchengetedza kureba kwe femoral neck.
