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]
X-ray at right shows same shoulder after reduction and internal rotation, revealing both a Bankart lesion and a Hill-Sachs lesion. Diagnosis can be suspected by history and physical examination which is usually followed by imaging. Because of the mechanism of injury, apprehension of anterior dislocation is common with provocative maneuvers.
Anterior shoulder dislocation while carrying a frail elder. A dislocated shoulder is a condition in which the head of the humerus is detached from the glenoid fossa. [2] 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]
Sprengel's deformity (also known as high scapula, scapular hypoplasia, or congenital high scapula) is a rare congenital skeletal abnormality where a person has one shoulder blade that sits higher on the back than the other. The deformity is due to a failure in early fetal development where the shoulder fails to descend properly from the neck to ...
A Bankart lesion is a type of shoulder injury that occurs following a dislocated shoulder. [3] It is an injury of the anterior ( inferior ) glenoid labrum of the shoulder. [ 4 ] When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it.
Separated shoulder; Other names: Acromioclavicular joint injury, acromioclavicular separation, AC joint separation, AC separation: An Xray showing a separated shoulder. Notice the separation between the end of the collarbone and the scapula. Specialty: Orthopedics, emergency medicine: Symptoms: Pain, deformity, decreased range of motion [1] [2 ...
The lesion is associated with any damage to the antero-inferior labrum. Most commonly due to anterior shoulder dislocation. The lesion often occurs after the initial dislocation. In chronic cases, there may be fibrosis and resynovialization of the labrum and periosteum. [citation needed] The lesion is best identified on MR arthrography.
PD-weighted MRI with fat saturation of the shoulder showing an ALPSA lesion An ALPSA (anterior labral periosteal sleeve avulsion ) lesion is an injury at the front of the shoulder associated with shoulder dislocation .
