MIS | Uphuculo lobuchwephesha-izinto eziluncedo kwezobuGcisa - Iziphumo zasemva kokusebenza | czmeditech

I-Minimally Invasive Spine System (MIS) yiteknoloji yezobugcisa eyenza unyango oluchanekileyo ngokusebenzisa izithintelo ezincinci kwiimeko ezifana neediski ze-herniated kunye ne-spinal stenosis.

Iinkcukacha zoyilo olutsha

Ubuncinci bezinto eziluncedo

Umothuko ophantsi

Uyilo oluncinci lokusika:

Izithintelo eziqhelekileyo ziyi-1-2 cm kuphela, ukunciphisa ukuhluthwa kwemisipha kunye nokulimala kwezicubu ezithambileyo.

Itekhnoloji yokubeka echanekileyo:

Ukuchaneka okuphuculweyo kokufakwa kofakelo kunye nokuhamba nge-intraoperative navigation (umz. O-arm, 3D-C-arm) okanye uncedo lwerobhothi (umz. Mazor X, Globus Medical).

Ukopha okucuthiweyo kuqhaqho:

Ubuchwephesha bokufikelela obuncinci bunciphisa umngcipheko wokulimala kwe-vascular, ngakumbi kubantu abadala okanye izigulane ezigulayo.

Ukuchacha ngokukhawuleza emva kokuhlinzwa

Ukuhlala ixeshana esibhedlele:

Uninzi lwezigulane zikhutshwa kwiiyure ezingama-24-48 emva kotyando, xa kuthelekiswa neentsuku ezi-3-5 zotyando oluvulekileyo lwemveli.

Ukushukuma kwangoko:

Intlungu engaphantsi kunye nokukhuselwa kwemisipha engcono kuvumela izigulane ukuba zibuyele kwimisebenzi yazo yemihla ngemihla ngokukhawuleza.

Ukulungiswa kweBiomechanical

Usetyenziso lwemathiriyeli emitsha:

umz. I-3D eprintiweyo ye-titanium alloys, PEEK (i-polyether ether ketone) imathiriyeli yokufezekisa i-modulus ye-elasticity esondele kwithambo kunye nokunciphisa i-masking masking.

Iinkqubo zozinziso ezinamandla:

ezinye izinto ezifakelwayo (umz. Dynesys, Coflex) zigcina ukushukuma komqolo kwaye zinciphisa umngcipheko wokuwohloka kwecandelo elikufutshane.

Iimpawu ezandisiweyo

Ukugubungela uluhlu olubanzi lwee-pathologies zomgogodla ezifana nesifo se-disc degenerative, i-lumbar spinal stenosis, i-spondylolisthesis encinci kunye ne-vertebral fractures.

临床案列

Oku kulandelayo ngamatyala ophando olumele kwiminyaka yakutshanje:

1. Ulingo olulawulwa ngokungakhethiyo lwe-lumbar spine fusion (TLIF)

Uyilo lofundo:

i-RCT elindelekileyo (2022) ithelekisa i-MIS-TLIF (i-invasive kancinane) kunye ne-TLIF evulekileyo.

Ubungakanani besampulu:

Izigulane ze-120 ezine-single-segment degenerative lumbar spine disease.

Iziphumo:

Ixesha lotyando:

ixesha elide kancinci kwiqela le-MIS (lithetha i-150 min vs. 130 min), kodwa i-60% iyancipha ukopha (<100 ml vs. 250 ml).

Iintlungu zasemva kotyando:

I-50% yokunciphisa amanqaku e-VAS kwiiveki ze-1 emva kokusebenza kwiqela le-MIS, akukho mmahluko omkhulu phakathi kwamaqela amabini emva kweenyanga ze-3.

Izinga lokudibanisa:

Unyaka we-1 we-postoperative CT ubonise> i-90% izinga lokuxutywa kumaqela omabini.

Iingxaki:

Izinga losulelo yi-2% kwiqela le-MIS vs. 8% kwiqela elivulelekileyo.

2. Uphononongo olude lwexesha elide lwenkqubo yokuzinzisa (Coflex)

Uyilo lofundo:

I-European 5-year follow-up study (2021) yokuvavanya ukufakwa kwe-Coflex yonyango lwe-lumbar spinal stenosis.

Ubungakanani besampulu:

Izigulane ezingama-80.

ISIPHUMO:

Uphuculo olusebenzayo:

i-ODI (i-index ye-dysfunction) yehla ukusuka kumanqaku angama-45 kwisiseko ukuya kumanqaku angama-20 kwiminyaka eyi-5.

UKWEHLWA KWECANDELO LOBUMELANI:

Kuphela i-12% yezigulane eziphuhliswe iingxaki zecandelo elisondeleyo, eliphantsi kakhulu kunokudibanisa okuqhelekileyo (~ 30%).

Izinga lokusebenza kwakhona:

ireyithi yokusebenza kwakhona yeminyaka emi-5 yesi-8%, ikakhulu ngenxa yokukhulula i-implants (4%) okanye ukuphindaphinda kweempawu.

3. Uphononongo lwamaziko amaninzi lokufakelwa kwe-MIS encediswa yirobhothi

Uyilo lofundo:

Uphononongo lokubuyela emva olupapashwe ngo-2023 ukuhlalutya iziphumo ze-MIS screw placement ngoncedo lwerobhothi yaseMazor.

Ubungakanani besampulu:

I-500 yokubeka i-screw (i-thoracolumbar spine).

Iziphumo:

Ukuchaneka:

I-98.6% yeendawo zokujija bezinelisayo (uGertzbein-Robbins ukwinqanaba A/B).

Iingxaki:

ireyithi yokulimala kwengcambu ye-nerve yi-0.4% xa kuthelekiswa ne-3-5% yokubekwa kwesandla sasimahla.
