Vacuum phenomenon in the shoulder refers to the presence of intra-articular gas in the shoulder joint.t is a very common occurrence, particularly in external rotation.

While a dislocation is a complete disunion, or separation, between the two articulating bones of the synovial joint, a subluxation is an incomplete disunion of the two articulating bones. In the case of a subluxation, the two bones that meet up will partially separate from each other and return to their normal position. This process is called spontaneous reduction. The bones continue to touch each other along the articulating surfaces, but not in the same nature as if they were not injured.
