This is the 15-letter plural of the noun HYPERABDUCTION
, more of which later in this article.
External rotation greater than 90[degrees] at the side is suggestive of anterior ligamentous hyperlaxity; asymmetrical hyperabduction
of more than 20[degrees] compared to the contralateral arm is indicative of a stretched inferior glenohumeral ligament.
Pectoralis minor tenotomy and anterior scalenotomy with special reference to the hyperabduction
syndrome and " effort thrombosis" of the subclavian vein.
The thrombosis is caused by trauma or repetitive muscular activity involving abduction or hyperabduction
of the upper extremity.
During VA monitoring, we compared the results for five shoulder postures: Usual and opposite positions (sitting and lying), and during provocative shoulder postures, including hyperabduction (hand high); Roos ("stick em up") and Adson's test ("military posture").

Previously, the name was designated according to the etiologies of compression, such as scalenus anticus, costoclavicular, hyperabduction, cervical rib, or first rib syndromes.
Wright (14) described the hyperabduction syndrome with compression in the costoclavicular area by the tendon of the pectoralis minor.
This injury is usually associated with a high energy trauma and is due to hyperabduction
and external rotation of the arm with retraction of the scapula.
The mechanism involves severe hyperabduction
and external rotation of the arm combined with scapular retraction.
The proposed mechanism of injury is a hyperabduction
and external rotation force versus a hyperabduction
and impaction force which would result in a Bankart lesion.
Multiple positional etiologies have been proposed, including hyperabduction
and a combination of flexion, adduction, and internal rotation.
