Symptoms include shoulder pain and instability. [2] Complications may include a Bankart lesion, Hill-Sachs lesion, rotator cuff tear, or injury to the axillary nerve. [1] A shoulder dislocation often occurs as a result of a fall onto an outstretched arm or onto the shoulder. [3] Diagnosis is typically based on symptoms and confirmed by X-rays. [2]
Type 3 AC joint separation on plain X ray. In a Type III AC separation both acromioclavicular and coracoclavicular ligaments are torn without significant disruption of the deltoid or trapezial fascia. [11] A significant bump, resulting in some shoulder deformity, is formed by the lateral end of the clavicle.
X-ray shoulder showing light bulb sign (left) in posterior shoulder dislocation. The image on the right was taken after reposition. The light bulb sign is a radiological finding observed on plain radiographs in the context of posterior shoulder dislocation. [1]
Lateral view demonstrating the articular surface of the right scapula is shown. Symptoms: Shoulder instability and widespread shoulder discomfort, and catching, locking, or popping feelings in shoulders. [1] Risk factors: Anterior shoulder dislocation and/or repeated anterior shoulder subluxations. [2] Diagnostic method: X-ray and MRI ...
Impingement syndrome can be diagnosed by a targeted medical history and physical examination, [11] [12] but it has also been argued that at least medical imaging [13] (generally X-ray initially) and/or response to local anesthetic injection [14] is necessary for workup. However, imaging studies are unable to show cause of shoulder pain in ...
The shoulder joint is a ball-and-socket joint between the scapula and the humerus. The socket of the glenoid fossa of the scapula is itself quite shallow, but it is made deeper by the addition of the glenoid labrum. The glenoid labrum is a ring of cartilaginous fibre attached to the circumference of the cavity.
Scapular fractures can be detected in the standard chest and shoulder radiographs that are given to patients who have had significant physical trauma, but much of the scapula is hidden by the ribs on standard chest X-rays. [4] Therefore, if scapular injury is suspected, more specific images of the scapular area can be taken. [4]
The human shoulder is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons. The articulations between the bones of the shoulder make up the shoulder joints .
