I-femoral neck fractures i-akhawunti ye-50% ye-hip fractures. Kwizigulane ezingenabantu abadala abaneentlungu zentamo ye-femoral, unyango lokulungiswa kwangaphakathi luhlala lunconywa. Nangona kunjalo, iingxaki zasemva kokuhlinzwa, ezinje ngokungabikho kokwaphuka, i-femoral head necrosis, kunye nokuncipha kwentamo ye-femal, zixhaphake kakhulu kuqheliselo lwezonyango. Okwangoku, uphando oluninzi lujolise kwindlela yokuthintela i-necrosis yentloko ye-femoral emva kokulungiswa kwangaphakathi kwe-femoral neck fractures, ngelixa ingqwalasela encinci inikezelwa kumbandela wokunciphisa intamo yowesifazane.
Okwangoku, iindlela zokulungiswa kwangaphakathi kwe-femoral neck fractures, kubandakanywa nokusetyenziswa kwe-screws ezintathu ze-cannulated, i-FNS (i-Femoral Neck System), kunye ne-screws ye-hip eguquguqukayo, zonke zijolise ekukhuseleni i-varus yentamo ye-femal kunye nokubonelela nge-axial compression ukuphepha ukungabikho. Nangona kunjalo, ukunyanzeliswa kwe-sliding okungalawulwayo okanye okugqithisileyo kukhokelela ekunciphiseni intamo ye-femoral. Ngokukhanya oku, iingcali zeSibhedlele seSibini sabantu esiNxibeleniswa neFujian University of Traditional Chinese Medicine, siqwalasela ukubaluleka kobude bentamo ye-femoral kwi-fracture ye-fracture kunye nomsebenzi we-hip, kucetywayo ukusetyenziswa kwe-"screw anti-shortening" ngokudibanisa ne-FNS yokulungiswa kwe-femoral neck fracture. Le ndlela ibonise iziphumo ezithembisayo, kwaye uphando lupapashwe kwiphephancwadi yakutshanje ye-Orthopedic Surgery.
Eli nqaku likhankanya iindidi ezimbini ze-"anti-shortening screws": enye isisikrufu esiqhelekileyo se-cannulated kunye nesinye isikrufu esinoyilo lwemisonto emibini. Kwiimeko ezingama-53 kwiqela le-screw anti-shortening, kuphela iimeko ezi-4 ezisebenzise isikrufu esinemisonto emibini. Oku kuphakamisa umbuzo wokuba ingaba i-screw equlethwe ngokuyinxenye enkonkxiweyo inefuthe elichasayo mfutshane.
Xa zombini izikrufu ezinemisonto e-cannulated kunye nezikrufu ezinemisonto emibini zahlalutywa kunye kwaye zithelekiswa nokulungiswa kwangaphakathi kwe-FNS yendabuko, iziphumo zibonise ukuba iqondo lokunciphisa kwiqela le-screw anti-shortening lalisezantsi kakhulu kuneqela le-FNS yesiqhelo kwinyanga ye-1, inyanga-3, kunye ne-1-nyaka yokulandela amanqaku, kunye nezibalo zokubaluleka. Oku kuphakamisa umbuzo: Ngaba isiphumo sibangelwe sisikrufu esiqhelekileyo se-cannulated okanye isikrufu esinemisonto emibini?
Eli nqaku libonisa iimeko ezi-5 ezibandakanya i-screws anti-shortening, kwaye xa kuhlolisiswa ngokusondeleyo, kunokubonwa ukuba kwiimeko ze-2 kunye ne-3, apho i-screws ene-cannulated edibeneyo isetyenzisiweyo, kwakukho ukuhoxiswa kwe-screw kunye nokunciphisa okubonakalayo (imifanekiso ebhalwe ngenombolo efanayo ihambelana nemeko efanayo).
Ngokusekwe kwimifanekiso yecala, ukusebenza kwesikrufu esinemisonto emibini ekuthinteleni ukwenza mfutshane kuyabonakala. Ngokubhekiselele kwi-screws e-cannulated, inqaku aliboneleli ngeqela elahlukileyo lokuthelekisa kubo. Nangona kunjalo, inqaku linika imbono exabisekileyo kwi-femoral neck fixation yangaphakathi, igxininisa ukubaluleka kokugcina ubude bentamo ye-femal.
