What is multidirectional shoulder instability?
Multidirectional instability is characterized as an imbalance between shoulder mobility and stability. The glenoid, glenoid labrum complex, glenohumeral ligaments as well as the negative pressure created within the congruent joint, all play roles as static stabilizers.
What provides multidirectional stabilization of the humerus?
The rotator cuff muscles are the subscapularis, the supraspinatus, the infraspinatus, and the teres minor. They are the primary stabilizers that hold the “ball” of the humerus to the glenoid “socket”.
What is the most common direction of shoulder instability?
The most common form of instability seems to be anterior and is probably because the joint capsule is at its weakest at the front of the joint.
What is Ambri shoulder?
Historically, clinicians used the acronyms TUBS and AMBRI to classify shoulder instability into two broad, etiologic categories: Traumatic, Unilateral, Bankart lesion, Surgery (TUBS) Atraumatic, Multidirectional, Bilateral, Rehabilitation, Inferior capsular shift (AMBRI)
How do you fix multidirectional shoulder instability?
Treatment for multidirectional shoulder instability
- Physical therapy. This can help restore strength and stability to your shoulder. Some treatments help reduce pain.
- Surgery. If physical therapy isn’t enough to heal your shoulder, you may need surgery to repair the tissues that stabilize the joint.
Is multidirectional instability genetic?
Multi-directional instability is often caused by loose ligaments. There are genetic conditions that can sometimes affect the ligaments and cause severe multi-directional instability.
Is multidirectional instability common?
Multidirectional instability (MDI) is a common shoulder problem seen in young athletes who specialize in overhead movements in their sports. It is a diagnosis specific to the glenohumeral joint of the shoulder and refers to a general laxity of the glenohumeral joint capsule.
How do you cure shoulder instability?
Applying cold packs or ice bags to the shoulder before and after exercise can help reduce the pain and swelling. NSAIDs (nonsteroidal anti-inflammatory drugs), which include aspirin, ibuprofen (Motrin, Advil, Nuprin, etc.) or ibuprofen-like drugs like Aleve can be used to reduce pain and swelling.
Which test would be (+) during a shoulder exam for a multi directional 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.
What is a putti Platt procedure?
Putti-Platt is one of the surgical treatment options for anterior shoulder instability. In this procedure, the flexible cord (tendon) of the subscapularis muscle is cut and then reattached to the head of the upper arm bone (humerus).
How is multidirectional instability calculated?
Your therapist will use a cluster of shoulder instability tests to help diagnose MDI. For a more detailed diagnosis, a physician may order x-rays to rule out bone fractures, and can order an MRI to diagnose injury within the shoulder complex, such as a muscle, capsule, or labral tear.
