Dynamic stabilizers of the glenohumeral joint
WebThese muscles contribute to dynamic glenohumeral joint stability through a number of mechanisms. Concavity compression, first described by Lippitt et al., 73 refers to the compressive forces placed on the glenohumeral joint during rotator cuff muscle cocontractions. These forces press the humeral head into the glenoid fossa, center the … WebBackground: Both static and dynamic factors are responsible for glenohumeral joint stability. We hypothesized that dynamic factors could potentially operate throughout the entire range of glenohumeral motion, although capsuloligamentous restraints (a static factor) have been thought to be primarily responsible for stability in the end-range of …
