I-Cancellous Screw: Isishwankathelo sokuSetyenziswa, iZalathisi, kunye nobuGcisa
Intshayelelo
I-Cancellous screws luhlobo lwe-screw ye-orthopedic esetyenziselwa ukulungisa amaqhekeza amathambo okanye i-grafts ekunyangeni ukuphuka, i-non-union, kunye nokunye ukulimala kwamathambo. Ezi zikrufu zisetyenziswa ngokubanzi kuqhaqho lwamathambo ngenxa yokuhambelana kwazo ne-biocompatibility, ukukhululeka kokufakwa, kunye neempawu ezigqwesileyo zomatshini. Kweli nqaku, siza kuxoxa ngezalathisi, ubuchule, kunye neziphumo zokusebenzisa izikrufu zokurhoxisa kutyando lwamathambo.
I-Anatomy kunye neePropathi zeMechanical ze-Cancellous Screw
Izikrufu zeCancellous zenziwe nge-titanium okanye intsimbi estainless kwaye zine-threaded shaft kunye nencam ye tapered. Imisonto kwi-shaft ibonelela ngokuthenga okugqwesileyo kwithambo elirhoxisiweyo kwaye ithintele ukuphuma, ngelixa i-tapered tip iququzelela ukufakwa lula ngaphandle kokonakalisa izicubu ezijikelezileyo. Izikrufu ziza ngobukhulu obahlukeneyo kunye nobude ukuze zivumelane nobukhulu bamathambo ahlukeneyo kunye neepateni zokuphuka. Iipropati zomatshini we-screenous screws zixhomekeke kwizinto eziphathekayo, ububanzi, ubude kunye noyilo lwentambo. Ukusetyenziswa kobukhulu obukhulu kunye nezikhonkwane ezinde kwandisa amandla okubamba kunye nokuzinza, ngelixa ukusetyenziswa kwe-diameter encinci kunye ne-screws emfutshane kunciphisa umngcipheko wokugqithisa kunye nokufuduka kwe-screw.
Iimpawu zokulungiswa kweScrewous Cancellous
Izikrufu zeCancellous ziboniswa kwiimeko ezahlukeneyo ze-orthopedic, kubandakanywa:
Ukuqhekeka kwamathambo amade, njenge-femur, i-tibia, kunye ne-humerus
Ukuqhekeka kwamathambo amancinci, njengesihlahla, iqatha kunye nonyawo
Iimanyano ezingezizo iimanyano kunye nokulibaziseka kweemanyano zoqhekeko
Ii-osteotomies, ezifana nokusikwa kwamathambo okulungisa ukukhubazeka okanye ukungahambi kakuhle
I-Arthrodesis, efana nokudityaniswa kwe-ankle, isihlahla, okanye umqolo
Ukulungiswa kwamathambo, njengokudityaniswa komqolo okanye ukwakhiwa kwakhona kwesiphene samathambo
Ubuchwephesha bokulungiswa kweScrewous Concellous
Ubuchwephesha bokulungiswa kwesikrufu esikhanyisayo kuxhomekeke kwisalathiso esithile kunye nepateni yokwaphuka. Imigaqo jikelele yokufaka isikrufu ibandakanya:
Ukubekwa ngokufanelekileyo kwesigulane kunye nokuchongwa kwendawo yokuphuka
Ukwenziwa komngxuma wokulinga kusetyenziswa intwana yokubhola okanye impompo
Umlinganiselo wesikrufu ubude kunye nedayamitha
Ukufakwa kwe-screw usebenzisa i-screwdriver okanye i-drill yamandla
Ukuqinisekiswa kwendawo ye-screw kunye nobunzulu kusetyenziswa iindlela zokucinga, ezifana ne-fluoroscopy okanye i-X-reyi
Izinto eziphambili ezichaphazela impumelelo yokulungiswa kwe-screw ye-Cancellous zibandakanya ukulungelelaniswa okufanelekileyo kwamaqhekeza okuqhekeka, ukunciphisa okwaneleyo kokwaphuka, ukubekwa kwesikrufu esifanelekileyo kunye nobude, kunye nokunyanzeliswa okufanelekileyo kwesikrufu. Iingxaki ze-cancelous screw fixation ziquka ukukhulula i-screw, i-screw breakage, i-screw migration, i-non-union, i-malunion, i-infection, kunye ne-nerve okanye ukulimala kwesitya.
Iziphumo zeCancellous Screw Fixation
Iziphumo zokurhoxiswa kokulungiswa kwezikrufu zixhomekeke kwisalathiso esikhethekileyo kunye nemiba yesigulana, efana neminyaka, ukugula, kunye nesimo sokutshaya. Ngokuqhelekileyo, ukulungiswa kwe-screwous screw kunika ukuzinza okugqwesileyo kunye nokunyanzeliswa kwamaqhekeza aqhekezayo, okukhokelela ekuphulukiseni ngokukhawuleza kwamathambo kunye nokubuyiselwa komsebenzi oqhelekileyo. Umyinge wempumelelo yokurhoxisa isikrufu sisuka kwi-80% ukuya kwi-95%, kuxhomekeke kwisalathiso kunye nepateni yokwaphuka. Iingxaki zokulungiswa kwesijiva sokurhoxiswa kunokukhokelela kwiziphumo ezibi kakhulu, njengokulibaziseka ukuphiliswa, ukungabikho komanyano, kunye neentlungu ezingapheliyo.
Ukuqukumbela
Izikrufu zeCancellous sisixhobo esisebenza ngeendlela ezininzi nesisebenzayo kutyando lwamathambo ukulungiselela ukulungiswa kokuqhekeka kwamathambo, ukuxhuzulwa, kunye nokudityaniswa. Ukusetyenziswa ngokufanelekileyo kwezikrufu zokurhoxisa kufuna ukuqondwa ngokucokisekileyo kwe-anatomy, imiqondiso, ubuchule, kunye neziphumo zenkqubo. Ukukhethwa kobungakanani obufanelekileyo be-screw, ubude, kunye nobuchule bokufaka kufuneka bulungelelaniswe kwipateni ethile yokuphuka kunye nemiba yesigulane. Ukusetyenziswa kwezikrufu zokurhoxisa kunokukhokelela kwiziphumo ezigqwesileyo kunye nokuphiliswa ngokukhawuleza, kodwa ukubeka iliso ngononophelo kunye nokulawulwa kweengxaki kubalulekile kwiziphumo ezilungileyo.
