I. Vim li cas lub hau ntswj cannulated muaj qhov?
Cov txheej txheem ntsia hlau cannulated ua haujlwm li cas? Siv cov xov hlau Kirschner nyias (K-wires) uas tau raug tho rau hauv pob txha los coj cov ntsia hlau mus rau hauv cov pob txha me me kom raug.
Kev siv cov xov hlau K-hlau zam kev tho qhov ntau dhau thiab tso cai rau kev kho cov pob txha uas yuav tshwm sim thaum lub sijhawm ntxig ntsia hlau. Cov cuab yeej khoob thiab cov ntsia hlau khoob raug ntxig rau hauv pob txha hla cov xov hlau K. Kev kho cov ntsia hlau cannulated yog qhov muaj txiaj ntsig zoo rau cov pob txha caj qaum kom ruaj khov cov pob txha tawg odontoid thiab kho qhov tsis ruaj khov atlantoaxial.
Cov ntsia hlau uas muaj cannulated muaj ntau qhov zoo dua piv rau cov ntsia hlau uas tsis muaj cannulated: 1) cov xov hlau K coj txoj haujlwm ntsia hlau mus rau hauv pob txha;
2) txoj kab ke K-wire ua rau kev hloov chaw yooj yim yog tias txoj kab ke thawj zaug tsis zoo tagnrho;
3) cov xov hlau K tso cai rau kev kho tas mus li ntawm cov pob txha tsis ruaj khov uas nyob ib sab;
4) Cov xov hlau K tiv thaiv kev txav mus los ntawm cov pob txha tsis ruaj khov thaum lub sijhawm ntxig ntsia hlau.
Cov teeb meem cuam tshuam nrog K-wire (kev tawg, kev hloov chaw, thiab kev nce qib) tuaj yeem txo qis siv cov txheej txheem phais mob meej. Ib lub cuab yeej tshwj xeeb cannulated ntsia hlau tau tsim tshwj xeeb rau kev kho lub caj dab sab saud kom tso cai rau kev khawb percutaneous siv cov khoom siv tunneling ntev, cov ntaub so ntswg, cov lus qhia laum, thiab K-wires ntev. Cov cuab yeej no tso cai rau kev xa cov cannulated ntsia hlau ntawm lub kaum sab xis qis rau tus txha nraub qaum los ntawm cov ntaub so ntswg mos ntev. Cannulated ntsia hlau muaj qhov zoo tseem ceeb piv rau cov ntsia hlau tsis yog cannulated rau kev kho ntawm lub caj dab tsis ruaj khov ntawm lub cev.
II.Qhov twg zoo dua cannulated screws lossis intrameduallary nails?
Ob qho tib si cov rau tes hauv medullary thiab cov rau tes cannulated yog cov khoom siv kho mob siv rau kev kho sab hauv ntawm cov pob txha tawg. Lawv txhua tus muaj lawv tus kheej qhov zoo thiab tsim nyog rau ntau hom pob txha tawg thiab kev xav tau kev kho mob.
| Hom | Qhov zoo |
| Cov rau tes hauv qab medullary | Qhov cuam tshuam ntawm kev kho cov rau tes hauv medullary rau kev tawg pob txha ntev yog qhov zoo, nrog rau kev raug mob tsawg dua thiab los ntshav tsawg dua. Kev kho rau tes hauv medullary yog rau kev kho hauv nruab nrab. Piv nrog cov phaj hlau, cov rau tes hauv medullary kuj tseem tuaj yeem tiv thaiv kev ncaj ncees ntawm daim nyias nyias extraosseous, tiv thaiv kev kho pob txha qeeb, thiab ua lub luag haujlwm hauv kev zam kev kis kab mob. |
| Cov Ntsia Hlau Cannulated | Nws feem ntau yog siv rau thaj chaw xws li pob txha caj dab femoral, nrog rau kev kho tshwj xeeb thiab kev nias. Ntxiv mus, qhov kev puas tsuaj yog me me heev thiab tsis tas yuav siv cov phaj hlau. |
III. Thaum twg yuav siv cov ntsia hlau cancellous vs cortical?
Cov ntsia hlau cancellous thiab cov ntsia hlau cortical yog ob hom orthopedic implants siv rau hauv kev kho pob txha, tab sis lawv tau tsim los rau ntau hom pob txha thiab muaj cov ntawv thov sib txawv:
Cov ntsia hlau Cancellous yog tsim tshwj xeeb rau kev siv rau hauv cov pob txha spongy, tsawg dua ntom, thiab cov pob txha trabecular, feem ntau pom ntawm qhov kawg ntawm cov pob txha ntev, xws li femur thiab tibia. Feem ntau siv rau hauv cov cheeb tsam uas cov pob txha muaj qhov ntau dua thiab tsawg dua ntom, xws li cov cheeb tsam metaphyseal ntawm cov pob txha ntev. Lawv feem ntau siv rau hauv cov txheej txheem cuam tshuam nrog tus txha nraub qaum, lub duav, thiab qee qhov ntawm lub xub pwg nyom thiab lub duav.
Cortical Screws yog tsim los siv rau hauv cov pob txha cortical uas tuab dua, uas tsim cov txheej sab nraud ntawm feem ntau cov pob txha thiab nyuaj dua thiab muaj zog dua li cov pob txha cancellous. Feem ntau siv rau hauv cov xwm txheej uas xav tau lub zog thiab kev ruaj khov ntau dua, xws li hauv kev kho cov pob txha tawg hauv diaphysis (ncej) ntawm cov pob txha ntev. Lawv kuj tseem siv rau hauv qee yam khoom siv kho sab hauv thiab cov phaj.
Hauv kev xaus lus, qhov kev xaiv ntawm cov ntsia hlau cancellous thiab cortical nyob ntawm hom pob txha uas raug kho thiab cov kev cai tshwj xeeb ntawm cov txheej txheem orthopedic. Cov ntsia hlau Cancellous yog qhov tsim nyog rau cov pob txha mos dua, muaj qhov ntau dua, thaum cov ntsia hlau cortical yog qhov zoo tagnrho rau cov pob txha ntom dua, uas muaj lub nra hnyav.
