Muaj ob lub ntsiab lus tseem ceeb ntawm kev txav chaw scapulohumeral rhythms . Qhov thib ib yog abduction ntawm glenohumeral sib koom.

Ntawm no, dab tsi yog qhov Scapulohumeral atherosclerosis?

Scapulohumeral rhiab heev : kev sib koom ua ke ntawm scapula thiab humerus tau ntsib thaum lub xub pwg nyom thiab kev txav chaw uas ib txwm pom tias tshwm sim ntawm qhov sib piv ntawm 2: 1 (2 degrees ntawm humeral flexion / abduction mus rau 1 degree ntawm scapular upward rotation).

Ib yam nkaus, dab tsi yog rov qab Scapulohumeral atherosclerosis? Keeb kwm yav dhau Me ntsis paub txog kinematic muaj nuj nqi ntawm thim rov qab tag nrho lub xub pwg arthroplasty (RTSA). Scapulohumeral kev sib dhos (SHR) yog qhov ntsuas ntau rau kev ntsuas cov leeg ua haujlwm thiab lub xub pwg sib koom tes. Lub hom phiaj ntawm txoj kev tshawb fawb no yog los sib piv SHR hauv xub pwg nrog RTSA rau lub xub pwg zoo.
