Chronopoulos et al. (2004) suggest a test item cluster of three provocative tests. these are the cross body adduction test, the ac resisted extension or shear test, and the active compression test also known as o’brien’s test. in case of a positive test for all three items, the sensitivity is at 25% and specificity is reported at 97%.
Pathology Of The Acromioclavicular Joint Ac Alai 3) a thickened or swollen ac joint, which in isolation was the most accurate item in the study. 4) absence of typical pain provocation during passive glenohumeral abduction. 5) absence of typical pain during external rotation performed at 90 degrees of abduction. the last two items might be a differentiating factor compared to other shoulder. The acromioclavicular joint is an important component of the shoulder girdle; it links the axial skeleton with the upper limb. this joint, a planar diarthrodial articulation between the clavicle and the acromion, contains a meniscus like fibrous disk that is prone to degeneration. the acromioclavicular capsule and ligaments stabilize the joint in the horizontal direction, while the. Acromioclavicular (ac) joint injury is a frequent diagnosis after acute shoulder trauma and is very common among athletic populations. it accounts for 40% to 50% of shoulder injuries in many contact sports. approximately 9% of shoulder girdle injuries cause damage to the ac joint. they are mostly minor sprains and occur five times more. Purpose. resisted ac joint extension test (or the ac resisted extension test) is used to help identify acromioclavicular joint pathology in both traumatic and non traumatic chronic overuse cases, [1] and can be useful in helping differentiate between ac joint and impingement syndromes. [2].

[2]. Anatomy and pathoanatomy. the ac joint is a relatively stiff structure, with strong posterior, superior, and anterior ligament components that are thicker on their acromial insertions than their clavicular insertions, and coracoclavicular (cc) ligaments that augment the stiffness. 1 the main functions of the ligaments as restraints to ac joint motion and facilitators of coupled rotational. The acromioclavicular joint is a common source of “shoulder pain” aside from the glenohumeral joint and rotator cuff. in the study by jordan et al. [ 1 ], symptomatic acromioclavicular joints were present in 23% of patients undergoing shoulder mri. acromioclavicular joint dislocation accounts for approximately 12% of all shoulder injuries.
