[Dynamic of the filling of glenohumeral joint.].
The experimental study analyzed ultrasonographic image of the artificial filling of adducted glenohumeral joint on a cadaver in the half-sitting position in dependence on the instilled volume of liquid. Evaluated on the basis of statistical methods are: minimum detectable volume (3,7 +/- 1,5 ccm), the volume of axillary recess (5,2 +/-1,9 ccm), the amount of liquid expanding the articular capsule and subsequently passing into communicating recesses (11,4 +/- 4,1 ccm), and approximate maximal volume of the joint (326,0 +/- 5,3 ccm). Also the proportion berween the maximum volume of the joint and preceding values was identified, outside the minimum detectable volume. Based on the results of the experimental study in comparison with practice the authors developed an auxiliary table evaluating the clinical and US image in relation to different degree of the filling of the glenohumeral joint. Key words: shoulder, ultrasonography, effusion, evacuation.
