Dab tsi ua kom pob txha pob txha ntawm cov pob qij txha?
pob txha muab cov duab, txhawb nqa, thiab qauv rau lwm cov ntaub so ntswg hauv lub cev. Nws kuj yuav pab tau cov pob qij txha. Pob txha mos kuj smoothens cov pob txha nto ntawm cov pob qij txha. Cov ntaub so ntswg dab tsi npog cov pob txha ntawm cov pob qij txha?
Puas yog pob txha pob txha pob txha zoo ib yam li meniscus?
Cov pob txha mos yog qhov tawv tab sis du npog ntawm qhov kawg ntawm cov pob txha hauv cov pob qij txha. Nws tso cai rau gliding yam tsis muaj kev tiv thaiv ntau thiab ua haujlwm nrog cov meniscus kom cushion kawg ntawm cov pob txha. Lub meniscus nyob nruab nrab ntawm lub femur thiab tibia.
Dab tsi qhov sib txawv ntawm cov pob txha pob txha thiab pob txha?
Cov pob txha pob txha yog tsim los ntawm osteons thiab tsim cov txheej txheem sab nraud ntawm txhua pob txha. Cov pob txha pob txha yog tsim los ntawm trabeculae thiab ua rau sab hauv ntawm txhua pob txha. Dab tsi yog qhov sib txawv ntawm cov pob txha pob txha thiab pob txha pob txha?
Puas yog lub pob txha pob txha pob txha pob txha?
CONCLUSIONS: vertebral endplate raug mob feem ntau pom hauv osteoporotic vertebral compression fractures. Dab tsi ua rau lub pob txha tawg? Nws yog kev xav tias, nyob rau hauv ntau qhov mob ntawm qhov mob qis qis, thawj qhov ua rau mob yog pob txha ntawm pob txha caj qaum los ntawm compression rog.
