1.Dab tsi yog femoral stalk

Taw qhia:

Lub femoral qia (Femoral Stem) yog ib feem ntawm cov hlau tivthaiv siv los hloov lub sab sauv ntawm tus neeg mob lub femur (thigh pob txha) nyob rau hauv kev kho mob hip hloov. Nws yog ib qho ntawm cov khoom tseem ceeb tshaj plaws ntawm cov khoom siv dag zog thiab ua lub luag haujlwm rau kev txuas mus rau lub taub hau femoral thiab noj cov khoom thiab txav ntawm lub duav sib koom ua ke. Lub luag haujlwm tseem ceeb ntawm lub femoral qia yog hloov lub zog ntawm lub duav sib koom ua ke thiab qis qis mus rau tus so ntawm cov pob qij txha pob txha, kom ntseeg tau tias qhov sib koom ua ke ruaj khov, xis nyob thiab ua haujlwm zoo.

Cov qauv thiab kev ua haujlwm ntawm femoral qia

Cov duab:

Cov qia femoral feem ntau yog tapered los yog cylindrical thiab yog tsim los kom phim lub cev ntawm tib neeg femur. Nws rov ua haujlwm ntawm lub duav pob qij txha los ntawm kev cog rau hauv lub femur thiab txuas mus rau lub taub hau femoral (lwm qhov ntawm cov pob qij txha cuav).

Lub luag haujlwm:

Lub femoral qia nqa feem ntau ntawm lub cev lub cev hnyav, yog li nws yuav tsum muaj lub peev xwm thauj khoom muaj zog thiab ruaj khov. Nws kuj yuav tsum tau biocompatible los xyuas kom meej osseointegration thaum siv mus sij hawm ntev.

Hom thiab tsim ntawm femoral stems

Hom femoral qia

Muaj ntau hom femoral shanks thiab cov uas muaj xws li:

Round shank:

Haum rau cov neeg mob uas yuav luag ib puag ncig femoral anatomy, nws yooj yim rau nruab, tab sis tej zaum yuav tsis ruaj ntseg fastened nyob rau hauv qee cov neeg mob osteoporosis.
Tsis tas li ntawd, qhov zoo ntawm puag ncig shanks suav nrog cov txheej txheem phais yooj yim thiab lub sij hawm cog lus luv luv. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias nyob rau hauv cov neeg mob uas tsis tshua muaj pob txha ntxhia pob txha los yog osteoporosis, lwm hom kab mob femoral zoo dua yuav tsum tau txiav txim siab kom muaj kev ruaj ntseg mus ntev.

Tapered shank:

Feem ntau siv nyob rau hauv cov neeg mob uas muaj ntau tapered femoral anatomy thiab ib tug tapered los yog nqaim femoral qia los pab kom ruaj ntseg femoral qia.

Adjustable shanks:

Qee lub femoral shanks yog tsim los nrog cov yam ntxwv kho tau uas tuaj yeem hloov kho rau tus neeg mob lub cev.

Progressive shanks:

Cov shanks no yog tsim los muab kev sib txawv ntawm kev ruaj ntseg thiab kev xa khoom thauj kom haum rau cov pob txha sib txawv thiab cov neeg mob xav tau.

Femoral shanks nrog coatings:

Xws li cemented lossis cementless (piv txwv li, osseointegrated), nyob ntawm tus neeg mob cov pob txha zoo thiab cov qauv femoral. Cov cemented version yog tsim rau cov neeg mob laus, thaum lub osseointegrated version yog tsim rau cov neeg mob uas muaj pob txha zoo.

Kev tsim ntawm femoral qia feem ntau suav nrog:

Kev txiav txim siab ntawm anatomical adaptations, xws li lub kaum sab xis, qhov ntev, thiab curvature ntawm femoral qia. Kev xaiv yog tsim los xyuas kom meej tias cov qia femoral ua rau kev sib cuag zoo nrog lub femur thiab nyob ruaj khov.
Adjustable tsim: Qee cov femoral stems yog tsim los nrog cov yam ntxwv kho tau uas tso cai rau qee qhov kev hloov kho thaum lub sijhawm phais kom hloov lawv mus rau cov qauv sib txawv.
