What is multidirectional instability

Multidirectional instability (MDI) is a debilitating condition that involves chronic subluxation or dislocation of the shoulder in >1 direction. Numerous proposed mechanisms of MDI exist, which occurs in the setting of redundant capsular tissue.

How do you fix multidirectional instability?

The treatment for MDI must be individualized for each patient. Most patients with MDI can be treated non-operatively with a physical therapy program that emphasizes muscular rehabilitation. Rehabilitation focuses on strengthening the rotator cuff muscles and periscapular muscles (those around the scapula).

How do you test for multidirectional instability?

The sulcus test. Caudal traction is applied to the humerus in an attempt to displace the humerus inferiorly. If this test is positive, multidirectional instability is present. The anterior apprehension test, or crank test, is also used to evaluate shoulder instability.

Is shoulder instability bad?

Instability is often associated with subluxation, which may be associated with pain and/or dead arm sensation. This is often what prompts the patient to seek medical attention.

What does an unstable shoulder feel like?

Often, the episodes of giving way occur with specific activities or positions of the arm, such as throwing a ball or reaching behind the body.

What is the difference between laxity and instability?

While joint laxity is normal, a high amount of laxity does not necessarily mean you have instability. Stability is a combination of the function of your static and dynamic stabilizing systems. Instability is when you have an issue with either (or both) of the static and dynamic stabilizers.

When is surgery needed for shoulder instability?

Generally, surgery is a recommended option for people experiencing shoulder instability, pain, or stiffness after six months of undergoing nonsurgical treatment after a shoulder dislocation. A bankart repair reattaches the labrum, which can tear during anterior dislocation, to the shoulder socket.

What structure provides multidirectional stabilization of the humerus?

In a healthy shoulder, the head of the humerus is stabilized within the glenoid fossa (glenohumeral joint) through multiple structures including (from the inside out) the labrum, glenohumeral ligaments, joint capsule, and rotator cuff muscles.

What causes anterior shoulder instability?

It is caused by trauma or injury to the glenohumeral joint in which the upper arm bone is dislodged from its usual position in the middle of the glenoid fossa, and there is no longer joint articulation. Anterior shoulder instability accounts for 95 percent of all acute traumatic shoulder dislocations.
