A bursa is located between the acromion and the rotator cuff tendons. A bursa is a lubricated sac of tissue that cuts down on the friction between two moving parts. Bursae are located all over the body where tissues must rub against each other. In this case, the bursa protects the ...

Firstly, the humerus in internal rotation during the empty can does not allow the greater tuberosity to clear from under the acromion during arm elevation, which can increase risk of subacromial impingement because of decreased subacromial space width.17,18 Secondly, abducting in extreme internal ...

The AI was measured as a ratio of the distance from the glenoid to the lateral edge of the acromion over the distance from the glenoid to the lateral edge of the greater tuberosity (Fig. 2)15. The AHI was measured by calculating the distance from the undersurface of the acromion to...
Type-III Injury: In this type, both the acromioclavicular ligaments and the coracoclavicular ligaments are completely ruptured and thecollarboneand acromion get totally separated. Causes of Shoulder Separation Or Acromioclavicular Joint Separation
Starting with supero-anterior labrum and biceps anchor tear, an accessory anterior-superior lateral portal is established at a position one cm anterolateral to the anterolateral acromion border. This portal is localized by an outside-in spinal needle technique. An accessory posterolateral portal was ...
