Hauv lub xub pwg nyom, lub sib koom capsule yog tsim los ntawm ib pawg ligaments uas txuas cov humerus mus rau glenoid. Cov ligaments no yog lub hauv paus ntawm kev ruaj ntseg rau lub xub pwg nyom. Lawv yog cov superior, nruab nrab thiab inferior glenohumeral ligaments. Lawv pab tuav lub xub pwg nyom nyob rau hauv qhov chaw thiab kom nws tsis txhob dislocating.
Hauv qhov no, peb qhov ligaments uas txhawb nqa lub xub pwg sib koom yog dab tsi?
Muaj peb cov leeg pob txha uas muab qee yam kev txhawb nqa mus rau pem hauv ntej ntawm lub xub pwg nyom ; tus superior, nruab nrab thiab inferior glenohumeral ligaments . Tus superior glenohumeral ligament ua haujlwm nrog coracohumeral ligament kom ruaj ntseg lub taub hau humeral.
Qhov thib ob, dab tsi ua kom ruaj khov ntawm glenohumeral sib koom? Qhov kawg ntawm scapula, hu ua glenoid , ua tau raws li lub taub hau ntawm humerus los ua a glenohumeral kab noj hniav uas ua raws li ib tug saj zawg zog pob-thiab-socket sib koom . Cov sib koom yog ruaj khov los ntawm lub nplhaib ntawm fibrous cov pob txha mos ib puag ncig glenoid , hu ua labrum.
Ib yam nkaus, tib neeg nug, dab tsi ligaments ruaj khov lub xub pwg sib koom?
Cov no yog cov ligaments tseem ceeb uas pab kom stabilize cov pob qij txha ntawm lub xub pwg nyom:
- Acromioclavicular ligaments (ntau) thiab coracoclavicular ligaments (muaj ob: trapezoid thiab conoid).
- Sternoclavicular ligaments (ntau) ruaj khov sternoclavicular (SC) sib koom ua ke.
Cov leeg twg txuas rau cov leeg pob txha?
Lub cuff rotator yog pab pawg plaub leeg uas nyob ib puag ncig ntawm lub xub pwg thiab ua rau lub xub pwg ruaj khov. Cov leeg ntawm lub cuff rotator yog supraspinatus , subscapularis , infraspinatus , thiab txi minor . Lub cuff ua raws li lub tsiav tshuaj glenohumeral thiab txuas rau lub taub hau humeral.

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?
