Unicompartmental hauv caug arthroplasty (UKA) yog ib qho kev phais rau tag nrho lub hauv caug arthroplasty (TKA) rau kev kho mob ntawm unicompartmental osteoarthritis. Txawm li cas los xij, cov ntaub ntawv ntawm qhov ua tsis tiav ntawm UKA qhia txog 7-xyoo txoj sia nyob ntawm 74%, uas yog qis dua li ntawm TKA (92%). Txawm hais tias cov neeg mob tus kheej yam tseem ceeb ua rau muaj kev pheej hmoo ntawm kev ua tsis tiav, xws li cov neeg mob yau thiab siab dua lub cev qhov ntsuas (BMI) tuaj yeem ua rau muaj kev pheej hmoo ntawm UKA tsis ua haujlwm, kev phais kev phais tau raug suav tias yog qhov tseem ceeb ntawm kev pheej hmoo rau kev ua tsis tiav thaum ntxov. Hauv UKA, nws yog qhov nyuaj kom ua tiav qhov kev pom zoo ntawm cov pob qij txha thiab kev hla dhau (overhang). Lub tibial prosthesis yuav tsum tau loj thiab implanted nyob rau hauv ib tug yam uas txo cov mos mos khaus khaus, thiab ib tug medial tibial overhang ntawm ntau tshaj 3 hli tau pom tias yog ib qho tseem ceeb txaus ntshai rau txo Oxford Knee Score (OKS) thiab muaj zog. Lub hom phiaj tseem ceeb ntawm txoj kev tshawb fawb no yog los soj ntsuam tag nrho cov kev kuaj mob thiab cov txiaj ntsig ntawm UKA.

Femoral caj dab pob txha yog ib qho ntawm feem ntau ntsib kev raug mob orthopedic hauv kev kho mob, feem ntau ntawm cov neeg mob laus suav nrog ntau dua 50% ntawm pob txha pob txha. Raws li kev txheeb cais, qhov tshwm sim ntawm femoral caj dab tawg tau maj mam nce hauv xyoo tas los no, nrog

Kaw txo yog cov txheej txheem minimally invasive uas yuav siv tau rau ruaj khov fractures ntawm extremities nrog tsis poob ntawm cov ntshav khiav, tsis muaj kev pheej hmoo ntawm kev kis kab mob, ceev functionality rov qab, txo nqi kho mob, thiab yuav siv tau rau kaw txo hollow ntsia hlau thiab intramedullary pin fixation kho ntawm ntau yam tsis ruaj tsis khov fractures, xws li femoral caj dab moribulars, tibfe fractures. pob txha, humeral qia fractures, thiab lwm yam, tshem tawm kev puas tsuaj ntawm cov ntshav ntws los ntawm incisional txo.

Kev tshem tawm ntawm cov ntsia hlau intramedullary yog ib txoj kev niaj hnub, raws li txhua lub chaw tsim khoom muab cov cuab yeej tshem tawm tsim nyog. Txawm li cas los xij, qhov xav tau tiag tiag kom tshem tawm cov ntsia hlau ua tiav intramedullary yog qhov tsawg. Thaum tus ntsia thawv intramedullary ruptures, qhov teeb meem no yog tshwj xeeb tshaj yog tsis yooj yim sua.

Intramedullary ntsia thawv yog dab tsi?Intramedullary nailing yog phais kho cov pob txha tawg thiab ua kom nws ruaj khov. Cov pob txha feem ntau kho los ntawm cov txheej txheem no yog tus ncej puab, ci ntsa iab, lub duav, thiab sab caj npab. Ib tug ntsia thawv ruaj khov los yog pas nrig yog muab tso rau hauv nruab nrab ntawm cov pob txha. Nws yuav pab kom koj muaj peev xwm muab qhov hnyav rau th
