A scapular fracture is a fracture of the scapula, the shoulder blade.The scapula is sturdy and located in a protected place, so it rarely breaks. When it does, it is an indication that the individual was subjected to a considerable amount of force and that severe chest trauma may be present. [1]
Supraspinatus outlet view X-ray, showing subacromial space measurement. The normal subacromial space in shoulder radiographs is 9–10 mm; this space is significantly greater in men, with a slight reduction with age. [2] In middle age, a subacromial space less than 6 mm is pathological, and may indicate a rupture of the tendon of the ...
Shoulder impingement syndrome is a syndrome involving tendonitis (inflammation of tendons) of the rotator cuff muscles as they pass through the subacromial space, the passage beneath the acromion. It is particularly associated with tendonitis of the supraspinatus muscle. [1] This can result in pain, weakness, and loss of movement at the ...
A bone fracture of the shoulder involves a partial or total crack through one of the three bones in the shoulder, the clavicle, the scapula, and the humerus. The break in a bone usually occurs as a result of an impact injury, such as a fall or blow to the shoulder. Fractures usually involve the clavicle or the neck (area below the ball) of the ...
The subacromial bursa is the synovial cavity located just below the acromion, which communicates with the subdeltoid bursa in most individuals, forming the so-called subacromial-subdeltoid bursa (SSB).
Localized pain on the anterior shoulder suggests subacromial impingement, whereas posterior shoulder pain suggests internal impingement. [45] For the diagnosis of full-thickness rotator cuff tear, the best combination appears to include once more the painful arc and weakness in external rotation, and in addition, the drop arm sign .

Symptoms include non-radiating pain which may make it difficult to move the shoulder. The presence of swelling or bruising and a deformity in the shoulder is also common depending on how severe the dislocation is. [2] [1] It is most commonly due to a fall onto the front and upper part of the shoulder when the arm is by the side. [2]
This is not the same as a "shoulder dislocation," which refers to dislocation of the glenohumeral joint. Acromioclavicular joint dislocation is particularly common in collision sports such as ice hockey , football , Judo , rugby and Aussie rules , and is also a problem for those who participate in swimming , horseback riding , mountain biking ...
