Where is the capsule in the shoulder joint?
The shoulder joint capsule refers to the group of ligaments that encapsulate the shoulder’s ball-and-socket joint. These ligaments connect the humerus (the upper arm bone) to the glenoid (the shoulder’s socket) and stabilize the joint.
What is a shoulder capsule injury?
Shoulder instability usually occurs when the lining of the shoulder joint (the capsule), ligaments or labrum become stretched, torn or detached, allowing the ball of the shoulder joint (humeral head) to move either completely or partially out of the socket.
What is the shoulder capsule called?
The muscles of the rotator cuff keep the humerus tightly in the socket. The socket, or the glenoid, is shallow and flat. It is rimmed with soft tissue called the labrum that makes a deeper socket that molds to fit the humeral head. Ligaments in the joint capsule also contribute to shoulder stability.
Can you tear your shoulder capsule?
When the shoulder joint ball slips out of the socket, the joint capsule (fiberous tissues that surround and protect the joint) can pull on the lower portion of the labrum and tear it.
Where is the weakest part of the shoulder joint capsule located?
The weakest area of the shoulder joint capsule is just anterior to the attachment of the long head of the triceps at the infraglenoid tubercle, and disloca- tions are most frequent in this inferior anterior region.
How do you fix a shoulder capsule?
A capsular shift is commonly performed using an arthroscope. In this procedure your surgeon tightens the capsule, including the ligaments that stabilize the shoulder. This is similar to when a tailor tucks loose fabric by overlapping and sewing the two parts.

- Slowly lower your forearm towards the bed till you feel a comfortable stretch at the back of the shoulder joint.

What muscles and ligaments strengthen the joint capsule of the shoulder?
The anterior portion of the capsule is reinforced by the superior, middle, and inferior glenohumeral ligaments which form a Z-shaped pattern on the capsule. The muscles of the rotator cuff act to reinforce the joint capsule superiorly, posteriorly, and anteriorly.
How long does shoulder capsule surgery take?
Arthroscopic surgical capsular release of your frozen shoulder normally takes one to two hours to complete. You will be put under general anesthesia, and you may also be given an interscalene block, which is a regional anesthetic that is administered through an injection in your neck and numbs your shoulder area.
