Cancellous Screw: Chidule cha Kagwiritsidwe, Zizindikiro, ndi Njira
Mawu Oyamba
Cancellous screws ndi mtundu wa zomangira za mafupa zomwe zimagwiritsidwa ntchito kukonza zidutswa za fupa kapena zomezanitsa pochiza zosweka, zosagwirizana, ndi kuvulala kwina kwa mafupa. Zomangira izi zimagwiritsidwa ntchito kwambiri popanga opaleshoni ya mafupa chifukwa cha biocompatibility, kuyika mosavuta, komanso makina abwino kwambiri. M'nkhaniyi, tikambirana zizindikiro, njira, ndi zotsatira za kugwiritsa ntchito zomangira zomangira pa opaleshoni ya mafupa.
Anatomy ndi Mechanical Properties of Cancellous Screw
Zomangira zomangira zimapangidwa ndi titaniyamu kapena chitsulo chosapanga dzimbiri ndipo zimakhala ndi ulusi wopindika komanso nsonga yopindika. Ulusi womwe uli pa shaft umapereka kugula kwabwino kwambiri mu fupa lotsekeka ndikuletsa kutuluka, pomwe nsonga yopindika imathandizira kuyika mosavuta popanda kuwononga minofu yozungulira. Zomangira zimabwera mosiyanasiyana komanso motalika kuti zigwirizane ndi kukula kwa mafupa ndi mapangidwe osweka. Kapangidwe ka zomangira zomangira zimadalira zinthu, m'mimba mwake, kutalika, ndi kapangidwe ka ulusi. Kugwiritsa ntchito zomangira zazikulu ndi zomangira zazitali kumawonjezera mphamvu yogwira ndi kukhazikika, pomwe kugwiritsa ntchito zomangira zazing'ono ndi zomangira zazifupi kumachepetsa chiopsezo choboola mochulukira komanso kusamuka kwa wononga.
Zizindikiro za Cancellous screw Fixation
Zomangira zoziziritsa kukhosi zimawonetsedwa pazinthu zosiyanasiyana zamafupa, kuphatikiza:
Kuthyoka kwa mafupa aatali, monga femur, tibia, ndi humerus
Kuthyoka kwa mafupa ang'onoang'ono, monga dzanja, akakolo, ndi phazi
Osakhala mabungwe ndi kuchedwa migwirizano ya fractures
Osteotomies, monga kukonza mafupa odulidwa chifukwa cha kupunduka kapena kusalongosoka
Arthrodesis, monga kuphatikizika kwa bondo, dzanja, kapena msana
Kukhazikika kwa mafupa, monga kuphatikizika kwa msana kapena kukonzanso chilema cha mafupa
Njira Zopangira Cancellous Screw Fixation
Njira yokhazikitsira screwous screw fixation imatengera zomwe zikuwonetsa komanso mawonekedwe osweka. Mfundo zazikuluzikulu za kuyika zomangira ndizo:
Kuyika koyenera kwa wodwalayo ndikuzindikiritsa malo ophwanyika
Kupanga dzenje loyendetsa pogwiritsa ntchito kubowola kapena pompopi
Kuyeza kutalika kwa screw ndi diameter
Kuyika wononga pogwiritsa ntchito screwdriver kapena kubowola mphamvu
Kutsimikizira malo a screw ndi kuya pogwiritsa ntchito njira zojambula, monga fluoroscopy kapena X-ray
Zinthu zazikuluzikulu zomwe zimakhudza kupambana kwa misala ya screw fixation ndi kuphatikiza koyenera kwa zidutswa zong'ambika, kuchepetsa kokwanira kwa thyoka, kuyika koyenera ndi kutalika kwa screw, komanso kulimba koyenera kwa screw. Zovuta za kukonzanso wononga wononga kumaphatikizapo kumasula wononga, kusweka, kusuntha wononga, kusalumikizana, malunion, matenda, ndi kuvulala kwa mitsempha kapena chotengera.
Zotsatira za Cancellous Screw Fixation
Zotsatira za kukonzanso zomangira zomangika zimatengera momwe akumvera komanso momwe wodwalayo alili, monga zaka, zovuta, komanso momwe amasuta. Ambiri, cancellous wononga fixation amapereka bata kwambiri ndi psinjika zidutswa fracture, amene amatsogolera kuchira msanga mafupa ndi kubwezeretsa ntchito yachibadwa. Kupambana kwa zomangira zomangira zomata kumayambira 80% mpaka 95%, kutengera chizindikiritso ndi mawonekedwe osweka. Zovuta za cancellous screw fixation zimatha kubweretsa zotsatira zoyipa, monga kuchedwa kuchira, kusalumikizana, komanso kupweteka kosalekeza.
Mapeto
Zomangira za Cancellous ndi chida chosunthika komanso chothandiza pakuchita opaleshoni ya mafupa pokonza zothyoka fupa, kumezanitsa, ndi kuphatikizika. Kugwiritsa ntchito koyenera kwa zomangira zomangira kumafunikira kumvetsetsa bwino za thupi, zowonetsa, njira, ndi zotsatira za njirayi. Kusankhidwa kwa screw kukula koyenera, kutalika, ndi njira yoyikapo kuyenera kugwirizanitsidwa ndi ndondomeko yeniyeni ya fracture ndi zifukwa za odwala. Kugwiritsa ntchito zomangira zowumitsa kumatha kubweretsa zotsatira zabwino komanso kuchira mwachangu, koma kuwunika mosamala ndikuwongolera zovuta ndikofunikira kuti pakhale zotsatira zabwino.
FAQs
Kodi screwlous screw ndi chiyani? Censuloous screw ndi zomangira za mafupa zomwe zimagwiritsidwa ntchito kukonza zidutswa za fupa kapena zomezanitsa pochiza zosweka, zosagwirizana, ndi kuvulala kwina kwa fupa.
Kodi zizindikiro za cancellous screw fixation ndi ziti? Zomangira zoziziritsa kukhosi zimasonyezedwa pamitundu yosiyanasiyana ya mafupa, kuphatikiza ma fractures, non-unions, osteotomies, arthrodesis, ndi kukonza mafupa.
Kodi ndi zinthu ziti zazikulu zomwe zimakhudza kupambana kwa cancellous screw fixation? Zinthu zazikuluzikulu zomwe zimakhudza kupambana kwa misala ya screw fixation ndi kuphatikiza koyenera kwa zidutswa zong'ambika, kuchepetsa kokwanira kwa thyoka, kuyika koyenera ndi kutalika kwa screw, komanso kulimba koyenera kwa screw.
Kodi zovuta za cancellous screw fixation ndi zotani? Zovuta za cancellous screw fixation zimaphatikizapo kumasula wononga, kusweka, kusuntha wononga, kusalumikizana, malunion, matenda, ndi kuvulala kwa mitsempha kapena chotengera.
Kodi zotsatira za cancellous screw fixation ndi zotani? Zotsatira za kusungunula wononga wononga zimatengera zomwe zikuwonetsa komanso zomwe wodwala akukumana nazo, koma nthawi zambiri, kukhazikika kwa zomangira kumapereka kukhazikika komanso kupanikizana kwa zidutswa zong'ambika, zomwe zimatsogolera kuchira msanga kwa mafupa ndikubwezeretsanso ntchito yabwinobwino.
