The shoulder is able to maintain great mobility with limited stability due to the static stabilizers, which maintain congruity, and dynamic stabilizers, which create compressive force at the glenohumeral joint. Which of the following is a static stabilizer?
Answer: 1
The labrum is a static stabilizer. Static stabilizers includes the bony structures, the glenohumeral ligaments, and the joint capsule. The rotator cuff muscles are the following: infraspinatus, supraspinatus, subscapularis, and trees minor. The scapular stabilizers rhomboids and serratus anterior are dynamic stabilizers.
