I-PFNA (Proximal Nail Antirotation), i-proximal femol femor anti-rotation intramentary nail. Ilungele izinhlobo ezahlukahlukene zokuqhekeka kwe-themelrochantteric sowesifazane kwabesifazane; ukuqhekeka okungaphansi; I-Femoral Neck Base Fractures; I-Femoral Netmot Fractures ihlanganiswe nemigodi yama-femord shaft fractures; Ama-femorvent Interrochanterteric Fractures ahlanganiswe ne-Femolf Shaft fractures.
Izici eziphambili ze-Nail Design kanye nezinzuzo
(1) Idizayini enkulu yezipikili iboniswe ngamacala angaphezu kuka-200,000 e-PFNA, futhi ithole umdlalo omuhle kakhulu nge-anatomy yomsele we-medullary;
.
(3) Nail eziyize, kulula ukufaka;
.
Kukhanya okuvunguza:
(1) Ukulungiswa okukodwa kwangaphakathi ngasikhathi sinye kuqeda ukujikeleza nokuqina kwe-angular;
(2) I-blade inendawo enkulu engaphezulu futhi kancane kancane yanda ububanzi obuyinhloko. Ngokushayela futhi ecindezela ithambo elikhanyisa, amandla okufaka ama-anchical blade angenziwa ngcono, alungele iziguli ezinama-fractures akhululekile;
(3) I-helical blade ifakwe kahle nethambo, elithuthukisa ukuqina futhi limelane nokujikeleza. Ukuphela kwe-Fracture kunekhono elinamandla lokuwa nokulimala kokuqina ngemuva kokutholwa.
Amaphuzu alandelayo kufanele anake ekwelapheni ukuqhekeka kwabesifazane ngeUkulungiswa kwangaphakathi kwe-PFNA:
(1) Iziguli ezindala ezindala zinenkinga yezifo eziyisisekelo zezokwelapha futhi zinokubekezelela okungafanele ukuhlinzwa. Ngaphambi kokuhlinzwa, isimo esijwayelekile sesiguli kufanele sihlolwe ngokuphelele. Uma isiguli singakubekezelela ukuhlinzwa, ukuhlinzwa kufanele kwenziwe kusenesikhathi ngangokunokwenzeka, futhi umlenze othintekile kufanele asetshenziswe ngaphambi kokuhlinzwa. Ukuvikela noma ukunciphisa ukwenzeka kwezinkinga ezahlukahlukene;
(2) Ububanzi be-cavity ye-medullary kufanele kukalwe kusengaphambili ngaphambi kokuhlinzwa. Ububanzi be-main intramentary nail yi-1-2 mm incane kune-cavity yangempela ye-medullary, futhi ayifanele ukubekwa okunodlame ukugwema ukuvela kwezinkinga ezinjenge-distal femur fracture;
(3) Isiguli siphezulu, umlenze othintekile uqondile, futhi ukujikeleza kwangaphakathi kungu-15 °, okulungele ukufakwa kwenaliti yemihlahlandlela kanye nesipikili esikhulu. Ukuphoqwa okwanele nokuncishiswa okuvaliwe kwama-fractures ngaphansi kwama-fluoroscopy kuyizikhiye zokuhlinzwa ngempumelelo;
.
.
(6) Ukuhlaselwa okuhlangene okuhlangene noma izingcezwana ezinde ezahlukene, kunconyelwa ukusebenzisa i-PFNA enwetshiwe, kanye nesidingo sokuncishiswa okuvulekile kuncike ekunciphisweni kokuphulwa nokuncipha ngemuva kokuncishiswa. Uma kunesidingo, ikhebula lensimbi lingasetshenziswa ukubopha ibhulokhi ye-fracture, kepha lizothinta ukuphulukiswa kokuqhekeka futhi kufanele kugwenywe;
.
Izinzuzo kanye nemikhawulo ye-PFNA
Njengohlobo olusha lweIdivaysi yokulungiswa kwe-intrametundary, I-PFNA iyakwazi ukudlulisa umthwalo ngokuxoshwa, ukuze izinhlangothi zangaphakathi nangaphandle ze-femur zingakwazi ukuthwala izingcindezi ezifanayo, ngaleyo ndlela zithole inhloso yokuthuthukisa ukuqina kanye nokusebenza kahle kokulungiswa kwangaphakathi kwama-fractures. Umphumela ohleliwe muhle njalonjalo.
Ukusetshenziswa kwe-PFNA kubuye kube nemikhawulo ethile, efana nobunzima ekubekeni isikulufa sokukhiya distal, ubungozi obukhulayo bokuqhekeka okuzungeze isikulufa sokukhiya, nobuhlungu endaweni yethanga elingaphandle elibangelwa ukucasuka kweqembu le-iliotiolial band. I-Osteoporosis, kanjaloUkulungiswa kwe-IntramentaryImvamisa inethuba lokwehluleka kokulungiswa kanye nokuqhekeka okungaqondile.
Ngakho-ke, ezigulini asebekhulile ezinama-interrochanterteric angazinzile aqhekekile nge-osteoporosis enzima, ukuthwala kwesisindo kusenesikhathi akuvunyelwe ngokuphelele ngemuva kokuthatha i-PFNA.
