Kuyini i-DHS ne-DCS?
I-DHS (Isikulufu Sesinqe Esinamandla)i-implant yokuhlinzwa esetshenziswa kakhulu ekwelapheni ukwaphuka kwentamo ye-femoral kanye nokuqhekeka kwe-intertrochanteric. Yakhiwe ngesikulufu kanye nohlelo lwepuleti oluhlinzeka ngokuqina okuzinzile ngokuvumela ukucindezela okunamandla endaweni yokuqhekeka, okukhuthaza ukuphulukiswa.
I-DCS (Isikulufu se-Dynamic Condylar)iyithuluzi lokuqinisa elisetshenziselwa ukwaphuka kwe-distal femur kanye ne-proximal tibia. Ihlanganisa izinzuzo zezikulufo eziningi ezifakwe ku-cannulated (MCS) kanye ne-DHS implants, ihlinzeka ngokucindezela okulawulayo okunamandla ngokusebenzisa izikulufo ezintathu ezihlelwe ngendlela eguquguqukayo engunxantathu.
Uyini Umehluko Phakathi kwe-DHS ne-DCS?
I-DHS (Dynamic Hip Screw) isetshenziswa kakhulu ekuqhekekeni kwentamo ye-femoral kanye ne-intertrochanteric, ihlinzeka ngokuqina okuzinzile ngesistimu yesikulufu kanye nepuleti. I-DCS (Dynamic Condylar Screw) yenzelwe ukuqhekeka kwe-distal femur kanye ne-proximal tibia, inikeza ukucindezela okulawulayo okunamandla ngokusebenzisa ukumiswa kwesikulufu esingunxantathu.
Isetshenziselwani i-DCS?
I-DCS isetshenziselwa ukwelapha ukwaphuka kwethambo ku-distal femur kanye ne-proximal tibia. Isebenza kahle kakhulu ekuhlinzekeni ukuzinza nokukhuthaza ukuphulukiswa kulezi zindawo ngokusebenzisa ukucindezela okulawulayo okulawulayo endaweni yokuphuka kwethambo.
Uyini Umehluko Phakathi kwe-DCS ne-DPL?
I-DPL (Ukuvala Ukucindezela Okunamandla)olunye uhlobo lohlelo lokuqinisa olusetshenziswa ekuhlinzeni kwamathambo. Nakuba zombili i-DCS ne-DPL zihlose ukunikeza ukuqinisa okuzinzile kwamathambo aphukile, i-DPL ngokuvamile isebenzisa izikulufo ezikhiyayo namapuleti ukuze kufezwe ukuqina, kanti i-DCS igxile ekucindezelweni okunamandla ukuze kuthuthukiswe ukuphulukiswa kwamathambo aphukile.
Uyini Umehluko Phakathi Kwe-DPS Ne-CPS?
I-DPS (Uhlelo Lwepuleti Elinamandla)futhiI-CPS (Uhlelo Lwepuleti Lokucindezela)Zombili zisetshenziselwa ukuqinisa ukuphuka. I-DPS ivumela ukucindezela okuguquguqukayo, okungathuthukisa ukuphulukiswa kokuphuka ngokukhuthaza ukunyakaza okuphakathi kwezingxenyana ngesikhathi sokuthwala isisindo. I-CPS, ngakolunye uhlangothi, inikeza ukucindezela okungaguquki futhi isetshenziselwa ukuphuka okuzinzile lapho ukucindezela okuguquguqukayo kungadingeki khona.
Uyini Umehluko Phakathi kwe-DCS 1 ne-DCS 2?
I-DCS 1 kanye ne-DCS 2 zibhekisela ezizukulwaneni noma ekucushweni okuhlukene kohlelo lwe-Dynamic Condylar Screw. I-DCS 2 inganikeza intuthuko maqondana nomklamo, izinto zokwakha, noma ubuchwepheshe bokuhlinza uma kuqhathaniswa ne-DCS 1. Kodwa-ke, umehluko othize uzoxhomeka ekubuyekezweni komkhiqizi kanye nentuthuko ohlelweni.
Ungayenza Kanjani i-DHS?
I-DHS inqubo yokuhlinzwa esetshenziselwa ukwelapha ukwaphuka kwe-proximal femur, okuhlanganisa ukwaphuka kwe-intertrochanteric kanye ne-subtrochanteric. Le nqubo ihilela izinyathelo ezilandelayo:
1. Ukulungiselela Ngaphambi Kokuhlinzwa: Isiguli sihlolwa kahle, futhi ukwaphuka kuhlukaniswa ngezifundo zezithombe ezifana ne-X-ray.
2. I-Anesthesia: Kunikezwa i-anesthesia ejwayelekile noma i-anesthesia yesifunda (isb., i-anesthesia yomgogodla).
3. Ukusikwa Nokuchayeka: Kwenziwa ukusikwa ohlangothini phezu kwesinqe, bese imisipha ihoxiswa ukuze kuvele i-femur.
4. Ukunciphisa Nokuqiniswa: Ukuphuka kuncishisiwe (kuqondile) ngaphansi kwesiqondiso se-fluoroscopic. Isikulufu esikhulu esikhanseliwe (isikulufu esilagiwe) sifakwa entanyeni nasekhanda le-femoral. Lesi sikulufu sifakwe ngaphakathi kwesikulufu sensimbi, esinamathiselwe epuletini elinamathele ku-cortex ye-femoral eseceleni ngezikulufu. I-DHS ivumela ukucindezela okunamandla, okusho ukuthi isikulufu singashelela ngaphakathi kwesikulufu, sikhuthaze ukucindezela nokuphulukiswa kokuphuka.
5. Ukuvalwa: Ukusika kuvalwe ngezingqimba, futhi amapayipi okudonsa amanzi angafakwa ukuze kuvinjelwe ukwakheka kwe-hematoma.
Kuyini Ukuhlinzwa kwe-PFN?
Ukuhlinzwa kwe-PFN (Proximal Femoral Nail) kungenye indlela esetshenziswa ukwelapha ukwaphuka kwe-proximal femoral. Kuhilela ukufakwa kwe-intramedullary nail emseleni we-femoral, okunikeza ukuqina okuqinile ngaphakathi kwethambo.
Iyini i-Z Phenomenon ku-PFN?
I-"Z phenomenon" ku-PFN ibhekisela enkingeni engaba khona lapho uzipho, ngenxa yokwakheka kwalo kanye namandla asetshenziswayo, kungabangela ukuwohloka kwe-varus kwentamo ye-femoral. Lokhu kungaholela ekungalungini kahle kanye nemiphumela emibi yokusebenza. Kwenzeka lapho i-geometry yesipikili kanye namandla asetshenziswa ngesikhathi sokuthwala isisindo kubangela ukuthi uzipho lufuduke noma luguquguquke, okuholela ekuguqukeni kwesimo "Z" esibonakalayo kuzipho.
Yikuphi Okungcono: I-Intramedullary Nail noma i-Dynamic Hip Screw?
Ukukhetha phakathi kwe-intramedullary nail (njenge-PFN) kanye ne-Dynamic Hip Screw (DHS) kuncike ezintweni eziningana, okuhlanganisa uhlobo lokuphuka, ikhwalithi yethambo, kanye nezici zesiguli. Izifundo zikhombisile ukuthi i-PFN ngokuvamile inikeza izinzuzo ezithile:
1. Ukulahlekelwa Yigazi Okuncishisiwe: Ukuhlinzwa kwe-PFN kuvame ukuholela ekulahlekelweni kwegazi okuncane ngesikhathi sokuhlinzwa uma kuqhathaniswa ne-DHS.
2. Isikhathi Esifushane Sokuhlinzwa: Izinqubo ze-PFN zivame ukushesha, zinciphisa isikhathi ngaphansi kwe-anesthesia.
3. Ukunyakaza Kwasekuqaleni: Iziguli ezelashwa nge-PFN zivame ukunyakaza futhi zithwale isisindo kusenesikhathi, okuholela ekululameni okusheshayo.
4. Izinkinga Ezincishisiwe: I-PFN ihlotshaniswa nezinkinga ezimbalwa, njengokutheleleka kanye ne-malunion.
Kodwa-ke, i-DHS isalokhu iyindlela efanelekile, ikakhulukazi ezinhlotsheni ezithile zokuqhekeka okuzinzile lapho ukwakheka kwayo kunganikeza ukulungiswa okusebenzayo. Isinqumo kufanele senziwe ngokusekelwe ezidingweni zesiguli ngasinye kanye nobuchwepheshe bukadokotela ohlinzayo.
Ingabe i-PFN ingasuswa?
Ezimweni eziningi, i-PFN (Proximal Femoral Nail) ayidingi ukususwa uma ukuphuka sekupholile. Kodwa-ke, ukususwa kungacatshangelwa uma isiguli sizwa ukungakhululeki noma izinkinga ezihlobene nokufakelwa. Isinqumo sokususa i-PFN kufanele senziwe ngokubonisana nodokotela ohlinza amathambo, kucatshangelwa izici ezifana nempilo yesiguli iyonke kanye nezingozi nezinzuzo ezingaba khona zenqubo yokususa.
