Key Features

Description

++

  • Humerus can dislocate anteriorly, posteriorly or inferiorly out of the socket.

  • Excessive translation of the humeral head in one or more directions

  • The instability may be associated with dislocation or subluxation associated with a trauma event.

  • GH instability may also be secondary to atraumatic factors associated with structural, postural, or movement dysfunction and possibly from recurrent minor injury to the structures of the glenohumeral joint.2-4

  • Symptomatology and management is different depending on the onset, degree, frequency, direction, associated pathology, neuromuscular control, and premorbid activity level.4

    • Anterior or anterior inferior instability

      • Mechanism

        • 95% of traumatic shoulder instabilities4

        • Can result in dislocation or subluxation

        • The humerus is forced into extreme abduction and external rotation and/or horizontal abduction.

        • Associated pathology includes Bankart lesion (anterior), humeral avulsion of GH ligaments (HAGL), and Hill-Sachs lesion.

      • Symptoms

        • Anterior and inferior shoulder pain

        • Instability and apprehension to abduction, external rotation and horizontal abduction motions

    • Posterior Instability

      • Mechanism

        • 5% of traumatic shoulder instabilities4

        • Can result in dislocation or subluxation

        • A fall on an outstretched arm of movements of extreme horizontal adduction or internal rotation

        • Associated pathology includes disruption of the posterior capsule, tearing of the teres minor, and reverse Hill-Sachs lesion.6

      • Symptoms

        • Posterior shoulder pain

        • Instability and apprehension to flexion, horizontal adduction, and internal rotation

    • Multidirectional instability

      • Mechanism

        • May occur without episode of trauma, however, patient may have a history of traumatic dislocation7

        • Can result in dislocation or subluxation

        • Instability and apprehension are present in multiple directions, although one direction may be the primary direction of instability.

        • Associated pathology depends on the primary direction of instability, duration of instability, and history of trauma.4,7

      • Symptoms

        • Pain and instability are often determined by the direction of primary instability and can vary based on activity.
