Dab tsi yog Distal Femur Intramedullary Nail (DFN)?
Distal Femur Intramedullary Nail (DFN) yog ib qho kev txhim kho sab hauv uas tsim los rau kev ruaj khov ntawm cov pob txha uas muaj feem cuam tshuam nrog qhov distal femoral metaphysis thiab diaphysis. Ntxig los ntawm qhov kev tawm tsam tsawg kawg nkaus, DFN system muab axial thiab kev sib hloov kev ruaj ntseg los ntawm kev tuav cov kwj dej medullary thiab anchoring cov pob txha tawg nrog cov ntsia hlau xauv.
Piv nrog rau kev kho cov phaj ib txwm, DFN systems ua haujlwm raws li kev cog qoob loo sib koom ua ke, ua rau lawv tshwj xeeb tshaj yog tsim rau cov pob qij txha ntawm cov pob qij txha hauv qhov chaw thaum ntxov thiab biomechanical stability yog qhov tseem ceeb.
Txhais thiab Core Function ntawm DFN System
Lub luag haujlwm tseem ceeb ntawm DFN system yog los kho femoral alignment, ntev, thiab kev sib hloov ruaj khov tom qab raug mob. Los ntawm centralizing fixation nyob rau hauv lub femoral kwj dej, tus ntsia thawv zoo kis physiological loads raws li txhua yam axis ntawm lub femur.
DFN vs Plate Fixation hauv Distal Femur Fractures
Thaum xauv daim hlau cia siab rau qhov kho qhov chaw thiab tej zaum yuav xav tau cov ntaub so ntswg nthuav dav, DFN cov tshuab txo qis periosteal cuam tshuam thiab khaws cia kev puas tsuaj ntawm biology. Qhov no ua rau intramedullary nailing ib qho kev xaiv hauv ntau lub zog siab lossis osteoporotic fracture scenarios.
Clinical Indications rau Distal Femur Intramedullary Nailing
Distal femur intramedullary rau tes yog qhia rau ntau yam kev raug mob thiab cov kab mob uas cuam tshuam nrog qis femur.
AO/OTA Distal Femur Fracture Classification Coverage
DFN systems feem ntau siv hauv AO/OTA 33-A thiab xaiv 33-C pob txha cov qauv, nrog rau cov kab mob ntxiv, metaphyseal, thiab qee qhov kev puas tsuaj hauv cov hlab ntsha thaum ua ke nrog cov txheej txheem txo kom tsim nyog.
Indications nyob rau hauv Osteoporotic thiab Geriatric Patients
Hauv cov neeg mob laus uas muaj pob txha osteoporotic, DFN fixation muaj kev txhim kho axial stability thiab txo kev pheej hmoo ntawm fixation tsis ua hauj lwm piv rau cov pa plating systems.
Tsim cov yam ntxwv ntawm DFN System
Anatomical Nail Geometry rau Distal Femur Alignment
Tus ntsia thawv nta ib qho kev tsim anatomically contoured uas phim lub ntuj curvature ntawm lub femur, ua kom yooj yim nkag thiab txo cov kev ua haujlwm tsis zoo.
Multi-Directional Distal Locking Options
Ntau qhov distal locking ntsia hlau configurations tso cai rau cov kws phais los hais txog cov qauv kev puas tsuaj thiab ua tiav kev ruaj ntseg hauv thaj tsam metaphyseal.
Proximal Locking thiab Length Stability Control
Proximal locking xaiv kom paub meej axial thiab rotational tswj, tswj cov ceg ntev thiab tiv thaiv implant migration thaum kho.
Biomechanical Zoo ntawm Distal Femur Intramedullary Nails
Load-Siv Fixation rau Early Weight Bearing
Los ntawm kev faib cov khoom thauj los ntawm cov kwj dej medullary, DFN systems txhawb kev rov ua haujlwm thaum ntxov thiab tswj qhov hnyav.
Txo cov ntaub so ntswg cuam tshuam piv rau Plating
Qhov cuam tshuam tsawg kawg nkaus ntawm DFN insertion khaws cia ib puag ncig cov ntaub so ntswg thiab cov hlab ntsha, txhawb kev rov qab sai dua thiab txo cov teeb meem.
Surgical Technique thiab Instrument Compatibility
Yam tsawg kawg nkaus Invasive Surgical Approach (MIS Technique)
DFN implantation yog ua los ntawm cov txheej txheem percutaneous uas txo cov sijhawm ua haujlwm, ntshav poob, thiab mob tom qab phais.
Dedicated Instrument Set for Accurate Nail Insertion
Cov cuab yeej ua tiav ua kom tiav cov ntsia hlau qhov chaw, tswj reaming, thiab raug ntsia hlau tso rau hauv lub sijhawm phais.
Khoom siv, Manufacturing, thiab Surface Treatment
Kev kho mob-Qib Titanium Alloy Siv
DFN system yog tsim los ntawm high-strength kho mob-qib titanium alloy, muab zoo heev biocompatibility thiab txhua yam kev ua tau zoo.
Nto Finish thiab Corrosion Resistance
Kev kho saum npoo av txhim kho kev qaug zog thiab kev tiv thaiv corrosion mus ntev, ua kom cov cog ruaj ruaj hauv vivo.
Cov txiaj ntsig kho mob thiab qhov zoo hauv kev coj ua thoob ntiaj teb
Stable Fixation nyob rau hauv Complex thiab Comminuted Fractures
DFN cov tshuab tau pom cov txiaj ntsig txhim khu kev qha hauv kev tswj hwm kev sib txuas lus thiab lub zog siab ntawm lub plab femur tawg thoob plaws ntiaj teb cov chaw raug mob.
Cov txiaj ntsig kho mob rau cov tsev kho mob thiab cov chaw raug mob
Cov kws phais neeg tau txais txiaj ntsig los ntawm kev ua haujlwm yooj yim ntawm kev phais mob, thaum lub tsev kho mob tau txais los ntawm kev txo qis thiab cov sijhawm luv luv ntawm cov neeg mob rov qab los.
Cov Qauv Zoo, Ntawv Pov Thawj, thiab OEM Muaj Peev Xwm Muaj Peev Xwm
Ua raws li CE thiab International Quality Standards
DFN system yog tsim nyob rau hauv cov ntawv pov thawj kev tswj hwm zoo thiab ua raws li cov cai tswj hwm kev kho mob thoob ntiaj teb.
OEM / ODM Customization rau thoob ntiaj teb Distributors
CZMEDITECH muab cov kev pabcuam OEM thiab ODM, txhawb cov kev qhia tshwj xeeb, kev tsim khoom lag luam, thiab ntim khoom rau thoob ntiaj teb orthopedic distributors.
Cov lus nug nquag nug txog DFN Systems
Cov pob txha puas zoo tshaj plaws kho nrog DFN system?
DFN systems yog qhov zoo tagnrho rau cov pob txha femur fractures uas yuav tsum tau kho cov kev kho mob hauv nruab nrog cev, tshwj xeeb tshaj yog nyob rau hauv cov teeb meem nyuaj lossis osteoporotic.
Puas yog DFN haum rau cov pob txha osteoporotic?
Yog lawm. Tus tsim intramedullary load-sharing muaj kev ruaj ntseg zoo rau cov neeg mob osteoporotic.
DFN vs locking phaj: uas zoo dua?
Qhov kev xaiv nyob ntawm hom pob txha thiab tus neeg mob, tab sis DFN feem ntau muab biomechanical zoo hauv axial loading.
Cov ntsia hlau diameters thiab ntev npaum li cas muaj?
DFN systems muaj nyob rau hauv ntau txoj kab uas hla thiab ntev kom haum raws li qhov sib txawv ntawm lub cev.
