Femoral neck fractures account ye50% yehudyu fractures. Kune varwere vasiri vakwegura vane femoral neck fractures, mukati mekugadzirisa kurapwa kunowanzokurudzirwa. Zvisinei, zvinetso zvepashure, zvakadai sekusabatanidzwa kwekutyoka, femoral head necrosis, uye femoral neck shortening, zvakajairika mukiriniki kudzidzira. Parizvino, tsvakurudzo yakawanda inotarisa nzira yekudzivirira femoral head necrosis mushure mekugadzirisa kwemukati kwekuputsika kwemutsipa wemukadzi, asi kuderera kunopiwa kune nyaya yekupfupisa kwemutsipa wevakadzi.
Parizvino, mukati mekugadzirisa nzira dzekutyoka kwemutsipa wevakadzi, kusanganisira kushandiswa kwematatu cannulated screws, FNS (Femoral Neck System), uye dynamic hip screws, zvose zvinovavarira kudzivirira femoral neck varus uye kupa axial compression kuti irege kusabatanidzwa. Nekudaro, kusingadzoreki kana kutsvedza zvakanyanya kutsvedza kunotungamira mukupfupika kwemutsipa wemukadzi. Tichifunga nezveizvi, nyanzvi kubva kuChipatara Chevanhu Chechipiri Yakabatana neFujian University yeTraditional Chinese Medicine, tichifunga nezvekukosha kwekureba kwemutsipa wemukadzi mukuporeswa kwekutyoka uye basa rehudyu, vakaronga kushandiswa kwe "anti-shortening screw" pamwe chete neFNS yefamoral mutsipa kuputsika kugadzirisa. Iyi nzira yakaratidza mhedzisiro inovimbisa, uye tsvagiridzo yakabudiswa mune yazvino chinyorwa chepepanhau Orthopedic Surgery.
Chinyorwa chinotaura nezvemhando mbiri dze "anti-shortening screws": imwe iri standard cannulated screw uye imwe screw ine mbiri-tambo dhizaini. Pamakesi makumi mashanu nenhatu ari muboka re-anti-shortening screw, makesi mana chete akashandisa siruu ine tambo mbiri. Izvi zvinomutsa mubvunzo wekuti chidimbu chakasungwa cannulated screw chine anti-kupfupisa maitiro.
Pakaongororwa ese ari maviri akarukwa-kanuni screws uye maviri-akarukwa-shinda akaongororwa pamwe chete uye zvichienzaniswa neyakajairwa FNS yemukati kugadzirisa, zvakabuda zvakaratidza kuti dhigirii rekupfupisa muboka re-anti-shortening screw rakanga rakaderera zvakanyanya pane reboka reFNS remwedzi 1, mwedzi mitatu, uye gore rimwe rekutevera mapoinzi, aine manhamba ezviratidzo. Izvi zvinomutsa mubvunzo: Mhedzisiro yacho inoenderana neyakajairwa cannulated screw kana iyo mbiri-yakapetwa screw?
Chinyorwa ichi chinopa 5 makesi anosanganisira anti-kupfupisa screws, uye pakunyatsotarisisa, zvinogona kuoneka kuti muzviitiko 2 ne3, pakashandiswa zvidimbu zvekanulated screws, paive neinocherekedza screw retraction uye kupfupisa (mifananidzo yakanyorwa nenhamba imwechete inoenderana neyakafanana kesi).
Zvichienderana nemifananidzo yenyaya, kushanda kweiyo mbiri-yakarukwa screw mukudzivirira kupfupisa kunonyatso kuoneka. Kana ari mascrews akaiswa cannulated, chinyorwa hachipi boka rakasiyana rekuenzanisa kwavari. Zvisinei, chinyorwa chacho chinopa maonero anokosha pamusoro pekugadzirisa kwemukati wemukadzi wemutsipa, kusimbisa kukosha kwekuchengetedza hurefu hwemutsipa.
