Cartilaginous pob qij txha txuas tag nrho los ntawm pob txha mos (fibrocartilage lossis hyaline). Cartilaginous pob qij txha tso cai ntxiv zog nruab nrab ntawm cov pob txha tshaj ib tug fibrous sib koom tab sis tsawg tshaj li mobile synovial sib koom. Kev sib koom ua ke ntawm manubrium thiab sternum yog piv txwv ntawm pob txha mos sib koom tes.
Raws li, qhov twg pom cov pob qij txha cartilaginous?
Cov no suav nrog fibrocartilaginous thiab hyaline pob qij txha , uas feem ntau tshwm sim ntawm midline. Qee qhov piv txwv ntawm qib ob pob qij txha cartilaginous hauv tib neeg lub cev yuav yog tus txiv neej sab nraud sib koom (nruab nrab ntawm manubrium thiab sternum), intervertebral discs, thiab pubic symphysis.
Kuj Paub, dab tsi yog qhov tseem ceeb cartilaginous sib koom? 1 Thawj pob txha pob txha mos (= synchondroses): Ib phaj ntawm hyaline pob txha mos txuas cov pob txha ntawm sib koom . Tsuas yog hyaline pob txha mos muaj kev koom tes, thiab pob qij txha yog immoveable. Piv txwv yog cartilaginous phaj epiphyseal uas cais cov epiphysis los ntawm diaphysis hauv cov pob txha ntev thaum loj hlob.
Kuj paub, txoj haujlwm ntawm kev sib koom tes yog dab tsi?
Lub ntsiab lus uas ob lossis ntau pob txha tau ntsib yog hu ua a sib koom los yog articulation. Cov pob qij txha Nws yog lub luag haujlwm rau kev txav mus los (piv txwv li, kev txav ntawm ceg ceg) thiab kev ruaj ntseg (piv txwv li, kev ruaj ntseg pom nyob rau hauv cov pob txha pob txha).
Dab tsi yog Synchondrosis sib koom?
Qhov twg qhov nruab nrab txuas yog pob txha mos hyaline, pob txha mos sib koom e npe a mob synchondrosis . Piv txwv ntawm a synchondrosis sib koom yog thawj sternocostal sib koom (qhov twg thawj tus tav ntsib raws li manubrium). (Tus so ntawm sternocostal pob qij txha yog synovial dav hlau pob qij txha .)

Pib 01/01/18, CPT code 20939 yuav tsum tau siv los tshaj tawm cov pob txha pob txha xav tau rau pob txha pob txha hauv kev phais pob txha
Hom pob txha mos twg yog pob txha mos pob txha?
Hyaline pob txha mos
Yam kev sib koom tes yog Midcarpal sib koom tes yog dab tsi?
Qhov nruab nrab nruab nrab ntawm pob qij txha yog ua ke ntawm synovial gliding pob qij txha ntawm cov kab sib thooj thiab nyob deb ntawm cov pob txha carpal. Zoo li lwm yam kev sib koom ua ke, cov pob txha carpal uas nyob ib sab hauv nruab nrab lub cev sib koom ua ke nrog cov pob txha hyaline thiab cov kab noj hniav sib koom ua ke nyob rau hauv cov tshuaj ua kua fibrous kab nrog synovial membrane
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Dab tsi ntawm cov pob txha ntawm tes yog lub luag haujlwm rau pob txha?
Kev kho pob txha yog ua kom ntseeg tau los ntawm ob hom cell: osteoclasts, uas resorb cov pob txha calcified matrix, thiab osteoblasts, uas yog lub luag haujlwm rau cov pob txha matrix tshiab. Thaum lub sij hawm kev loj hlob, cov pob txha tsim tshaj cov pob txha resorption, ua rau cov pob txha expansion
