Sachatello was the first to suggest a role for the axillary arch muscle in the hyperabduction
syndrome; reported a patient with high-grade intermittent obstruction of the axillary vein due to the anomalous AAM.
The most common collateral ligament injury in the hand involves the ulnar collateral ligament of the thumb, usually due to a violent hyperabduction
mechanism and commonly referred to as "gamekeepers" or "skiers" thumb (Figure 12).
This is the 15-letter plural of the noun HYPERABDUCTION
, more of which later in this article.
16) Motions such as repetitive hip hyperabduction
and lumbar hyperextension, a movement commonly seen in sports, can induce sheering at the pubic symphysis and may lead to a tear or series of microtears of the rectus abdominis muscle or tendon as it inserts onto the pubis.
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.
Out of 28 patients who had abnormal Doppler study (subclavian vessel compression), only 2 confirmed to have delay in flow on subclavian vessels on hyperabduction
during postoperative follow-up.
test: an assessment of the laxity of the inferior glenohumeral ligament.
Pectoralis minor tenotomy and anterior scalenotomy with special reference to the hyperabduction
syndrome and " effort thrombosis" of the subclavian vein.
The mechanism of thrombosis is through a thoracic outlet compression and/or repetitive intimal strain of the axillary or subclavian vein by retroversion and hyperabduction
of the arm.
and lateral rotation of the shoulder may press excessive stretch on the neurovascular structures, thereby giving rise to neurological and vascular symptoms in the arm (Daskalakis, 1983).
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").
WASHINGTON -- Hyperabduction
of the last brace to 60%-70% significantly reduces the risk of relapse and the need for surgery in children who are treated for clubfeet with the Ponseti method, Matthew E.
