What causes a Bankart lesion?
What causes a Bankart lesion?
A Bankart lesion is a lesion of the anterior part of the glenoid labrum of the shoulder. This injury is caused by repeated anterior shoulder subluxations. The dislocation of the shoulder joint (anterior) can damage the connective tissue ring around the glenoid labrum.
What is a Hill-Sachs defect?
A Hill-Sachs lesion is a fracture in the long bone in the upper arm (humerus) that connects to the body at the shoulder. You doctor might have discovered this condition if you’ve experienced a dislocated shoulder.
What is the primary and most common symptom of a posterior shoulder dislocation?
Patients with posterior shoulder instability primarily complain of aching pain and weakness along the posterior joint line, biceps tendon, or superior aspect of the rotator cuff. Symptoms intensify with the arm in 90° forward flexion, adduction, and internal rotation.
What is a tubs injury?
Summary. Traumatic instability (TUBS) is instability that arises from an force large enough to injure some of the major supporting structures of the joint, such as the glenohumeral capsule, ligaments, rotator cuff, or the bone of the humerus or glenoid.
What is an Alpsa lesion?
An ALPSA lesion refers to a detachment of the anteroinferior labrum from the glenoid. The scapular periosteum is unruptured but widely lifted or stripped. The labrum remains attached to the periosteum and can rotate medially to a position along the anterior surface of the scapular neck.
How do you know if you have a Bankart lesion?
Symptoms of a Bankart lesion can include:
- Pain. When reaching overhead, at night, or with daily activities.
- Instability and weakness. The shoulder may feel ‘loose’.
- Limited range of motion.
- Mechanical symptoms.
How do you fix a Hill-Sachs lesion?
Large or engaging Hill-Sachs lesions are addressed by either reconstructing (rebuilding) any lost bone on the glenoid side or performing a “Remplissage” procedure which repairs the posterior capsule and rotator cuff tendon to the Hill-Sachs bone defect.
Does posterior shoulder dislocation require surgery?
Posterior shoulder stabilization surgery is performed to improve the stability and function of the shoulder joint and prevent recurrent dislocations. It can be performed arthroscopically or through open surgery, depending on your condition.
Which nerve is injured in posterior shoulder dislocation?
The posterior branch also gives rise to the superior lateral brachial cutaneous nerve, innervating the skin of the proximal lateral arm. Whilst all nerves of the brachial plexus are at risk of injury during glenohumeral dislocation, the most commonly injured is the axillary nerve.
What is a bony Bankart lesion?
An osseous Bankart lesion is commonly seen in patients with an anterior shoulder dislocation. It is defined as a detachment of the anteroinferior labrum associated with a glenoid rim fracture. Radiological studies are crucial not only for detecting glenoid bone defects but also for measuring the amount of bone loss.
What is an ALPSA?
An ALPSA (anterior labral periosteal sleeve avulsion) lesion is an injury at the front of the shoulder associated with shoulder dislocation.
What is a Remplissage?
Remplissage is a French term that means “To Fill the Defect”. Thus in this procedure an additional pair of anchors are placed into the Hill-Sachs lesion and the infraspinatus rotator cuff tendon is repaired into the defect to fill the defect. This serves as a checkrein to prevent any further anterior instability.
Where are the labrum and periosteum torn in ALPSA?
An ALPSA lesion is an anterior labroligamentous periosteal sleeve avulsion. ALPSA is a variation of the Bankart lesion where the anterior inferior labrum is torn and the labrum, inferior glenohumeral ligament and intact scapular periosteum are stripped and displaced medially on the glenoid neck.
What kind of injury causes an ALPSA lesion?
It is often the result of chronic injury rather than acute dislocation; the incidence of ALPSA lesions increases in patients with multiple dislocations. An ALPSA lesion refers to a detachment of the anteroinferior labrum from the glenoid. The scapular periosteum is unruptured but widely lifted or stripped.
What is a Perthes lesion of the shoulder?
Perthes lesion of the shoulder is one of the types of the anterior glenohumeral injury in which the anterior inferior labrum is torn and lifted from the edge of the glenoid 1 but still attached to the intact lifted periosteum from the anterior aspect of the glenoid.
What kind of lesion is an anterior labroligamentous periosteal sleeve Avion?
An anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesion is similar to a Bankart lesion, in that it too is usually due to anterior shoulder dislocation and involves the anterior inferior labrum. Article: Epidemiology.
