Zisebenza njani izikrufu ezitshisiweyo? Ukusebenzisa iingcingo zeKirschner ezibhityileyo (iingcingo ze-K) eziye zagrunjwa kwithambo ukuze ziqondise iitrakethi ze-screw ngokuchanekileyo zibe ngamaqhekeza amancinci.
Ukusetyenziswa kweengcingo ze-K kuthintela ukugrumba ngokugqithisileyo imingxuma yokulinga kwaye ivumela ukulungiswa kwamaqhekeza amathambo akufuphi ngexesha lokufakwa kwesikrufu. Izixhobo eziHollow kunye nezikrufu ezingenanto zifakwe kwithambo phezu kwe-K-ingcingo. I-cannulated screw fixation iluncedo kumqolo wesibeleko ukuzinzisa i-odontoid fractures kunye nokunyanga ukungazinzi kwe-atlantoaxial.
Izikrufu ze-Cannulated zineenzuzo ezininzi xa kuthelekiswa nezikhonkwane ezingenayo i-noncannulated: 1) i-K-ingcingo zikhokela indawo ye-screw kwithambo;
2)i-K-wire trajectory yenza ukuphinda kubekwe lula ukuba i-original trajectory yayingafanelekanga;
3)i-K-ingcingo zivumela ukulungiswa okuqhubekayo kwamaqhekeza amathambo angazinzanga;
I-4)Iingcingo ze-K zithintela ukuhamba kweengceba zamathambo ezingazinzanga ngexesha lokufakwa kwesikrufu.
Iingxaki ezinxulumene nocingo lwe-K (ukwaphuka, ukubekwa ngokutsha, kunye nokuqhubela phambili) zinokuncitshiswa kusetyenziswa iindlela ezichanekileyo zokusebenza. Inkqubo ekhethekileyo yesixhobo se-screw e-cannulated yaphuhliswa ngokukodwa ukulungiswa komlomo wesibeleko ukuze kuvumeleke ukugrumba nge-percutaneous kusetyenziswa izixhobo ezinde ze-tunnel, i-tissue sheaths, i-drill guides, kunye ne-K-ingcingo ezide. Ezi zixhobo zivumela ukuhanjiswa kwe-screws e-cannulated kwi-engile ephantsi ukuya kumqolo ngokusebenzisa i-trajectories ye-soft-tissue emide. Izikrufu ze-cannulated zineenzuzo ezibalulekileyo xa kuthelekiswa nezikrufu ezingenayo i-noncannulated zokulungiswa komqolo wesibeleko ongazinzanga kwisistim.
II.Yeyiphi engcono izikhonkwane ezinkonkxiweyo okanye iinzipho ze-intrameduallary?
Zombini izikhonkwane ze-intramedullary kunye nezikhonkwane ezixutywe zizixhobo zonyango ezisetyenziselwa ukulungiswa kwangaphakathi kweefractures. Ngamnye unenzuzo yakhe kwaye ifanelekile kwiindidi ezahlukeneyo zokuphuka kunye neemfuno zonyango.
| Uhlobo | Inzuzo |
| I-Intramedullary Nail | I-intramedullary nail fixation effect kwi-stable fractures yamathambo amade ilungile, inokulimala okuncinci kunye nokopha okuncinci. Ukulungiswa kwezikhonkwane ze-Intramedullary zezokulungiswa okuphakathi. Xa kuthelekiswa namacwecwe ensimbi, izikhonkwane ze-intramedullary zinokukhusela ingqibelelo ye-membrane ye-extraosseous, ukuthintela ukulibaziseka ukuphulukiswa kokuphuka, kunye nokudlala indima ekuphepheni ukusuleleka. |
| I-Cannulated Screw | Isetyenziswa kakhulu kwiindawo ezifana nokuphulwa kwentamo ye-femoral, kunye nokulungiswa okukhethekileyo kunye nemiphumo yoxinzelelo. Ngaphezu koko, umonakalo uncinci kakhulu kwaye akukho zicwecwe zensimbi ezifunekayo. |
III.Kusetyenziswa nini ukukhansela vs izikrufu zecortical?
I-Cancellous screws kunye ne-cortical screws zombini iindidi zokufakelwa kwamathambo ezisetyenziselwa ukulungiswa kwamathambo, kodwa ziyilelwe iintlobo ezahlukeneyo zamathambo kwaye zinezicelo ezahlukileyo:
I-Cancellous Screws zenzelwe ngokukodwa ukusetyenziswa kwi-spongy, i-dense encinci, kunye ne-trabecular bone tissue, efumaneka ngokuqhelekileyo ekupheleni kwamathambo amade, njenge-femur kunye ne-tibia.Ngokuqhelekileyo isetyenziswe kwiindawo apho ithambo lincinci kwaye lincinci, njengemimandla ye-metaphyseal yamathambo amade. Zihlala zisetyenziswa kwiinkqubo ezibandakanya umqolo, i-pelvis, kunye neendawo ezithile zegxalaba kunye ne-hip.
I-Cortical Screws yenzelwe ukusetyenziswa kwi-denser, i-cortical bone, eyenza umaleko wangaphandle wamathambo amaninzi kwaye iqinile kwaye yomelele kunethambo elirhoxisiweyo. Ngokuqhelekileyo isetyenziswe kwiimeko apho kufuneka amandla amakhulu kunye nokuzinza, njengokulungiswa kweefractures kwi-diaphysis (shaft) yamathambo amade. Zikwasetyenziswa kwizixhobo ezithile zokulungiswa kwangaphakathi kunye namacwecwe.
Isishwankathelo, ukhetho phakathi kwe-cancellous kunye ne-cortical screws kuxhomekeke kuhlobo lwethambo olusisigxina kunye neemfuno ezithile zenkqubo yamathambo. I-Cancellous screws ifanelekile kwithambo elithambileyo, elinobuqhophololo, ngelixa i-cortical screws ifanelekile kwi-denser, ithambo elithwele umthwalo.
