Cov Subtalar Sib Koom . Cov subtalar sib koom tes yog kev sib txuas ntawm ob ntawm cov pob txha tarsal hauv ko taw - talus thiab calcaneus. Cov sib koom yog cais cov txheej txheem raws li synovial sib koom , thiab ua haujlwm zoo li lub dav hlau synovial sib koom.
Tsis tas li ntawd, qhov sib koom ua ke subtalar yog dab tsi?
Hauv tib neeg lub cev, qhov subtalar sib koom tes , tseem hu ua talocalcaneal sib koom , yog a sib koom ntawm ko taw. Nws tshwm sim ntawm lub rooj sib tham ntawm talus thiab calcaneus.
Ib sab saum toj no, kev txav txav tshwm sim ntawm qhov sib koom ua ke li cas? Cov pob qij txha txav mus rau hauv lub dav hlau triaxial, uas tso cai rau lus tsa suab ntawm flexion/extension, inversion/eversion, thiab adduction/abduction.
Cov lus nug tseem yog, dab tsi ua rau Talocrural sib koom?
Cov talocrural sib koom yog pob khawm synovial sib koom uas txuas rau qhov kawg ntawm tibia thiab fibula hauv qis qis nrog qhov sib thooj kawg ntawm talus. Kev sib txuas ntawm tibia thiab talus dais hnyav ntau dua li ntawm cov fibula me thiab cov talus.
Puas yog qhov sib koom ua ke yog pob khawm sib koom?
Koj pob taws sib koom yog lwm hom pob khawm sib koom . Paub tias yog thaj av talocrural, qhov no sib koom yog lub luag haujlwm rau kev txav ntawm koj txhais taw ntawm pob taws. Zoo li lub hauv caug sib koom , qhov no pob khawm sib koom yog qhov tshwj xeeb hauv qhov uas nws tso cai rau qee sab mus rau sab kev txav mus los. Cov subtalar sib koom tes tso cai rau inversion thiab eversion ntawm ko taw.

Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm 'crude' kov thiab 'nplua' kov qhov hnov? Nyuaj kov yog hais txog kev nkag siab los ntawm kev txhawb nqa ntawm cov neeg txais khoom ntawm qhov tsis nkag siab nrog cov teb loj. Hauv kev sib piv, kev kov zoo yog hais txog cov neeg txais khoom ntawm kev nkag siab siab nrog cov chaw txais me me
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
Hom kev sib koom ua ke yog qhov sib koom ua ke ntawm atlantoaxial?
pivot sib Tom qab ntawd, ib tug kuj yuav nug, hom kev sib koom ua ke yog atlanto occipital joint? condyloid Ib yam li ntawd, cov lus tsa suab twg yog qhov sib koom ua ke ntawm atlantoaxial tso cai? Lub atlas thiab axis tshwj xeeb ua haujlwm nrog ligaments txav caj dab.
Qhov kev txav twg tshwm sim ntawm qhov sib koom ua ke subtalar?
Lub kinematics ntawm lub subtalar sib koom tso cai rau kev sib koom ua ke ntawm inversion/adduction thiab eversion/abduction ntawm rearfoot (Fig. 11.15). (Nco ntsoov tias cov lus tsa suab no yog cov khoom ntawm supination thiab pronation, ntsig txog.)
