[The role of soft tissues in downward stability of the glenohumeral joint--an experimental study with fresh cadavers].
Inferior stabilizing mechanism was studied after anatomical dissection of vertical stabilizing tissues in 98 fresh shoulder joints from human autopsies and measuring relative restraint by stabilizing tissues in 8 fresh shoulder specimens from monkeys. This results demonstrated that the coracohumeral ligament and supraspinatus tendon were most important structure as static and dynamic stabilizers, and closely interacted with each other in preventing inferior subluxation of the glenohumeral joint.
