A Kim lesion is a concealed tear at the posterior glenoid chondrolabral junction accompanied by a concealed partial detachment of the deeper portion of the labrum from the glenoid rim.
What is a Bennett lesion?
A Bennett lesion is a bony spur at the posterior glenoid that is often seen in baseball players and usually asymptomatic. However, it sometimes becomes painful, but the mechanism of throwing pain is still unknown.
Is a slap tear the same as a labrum tear?
A SLAP tear is also referred to as a labral tear, or a tear or lesion to the labrum. This injury tends to develop over time due to repetitive movements. It can also result from acute trauma or age.
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.
What is a reverse Bankart lesion?
Reverse Bankart lesion is defined as the detachment of posteroinferior labrum with avulsion of posterior capsular periosteum. This leads to laxity of the posterior band of the inferior glenohumeral ligament with posterior displacement of the humeral head.
What is a reverse Hill-Sachs lesion?
Reverse Hill-Sachs defect, also called a McLaughlin lesion, is defined as an impaction fracture of anteromedial aspect of the humeral head following posterior dislocation of the humerus. It is of surgical importance to identify this lesion and correct it to prevent avascular necrosis.
What is glenoid hypoplasia?
Glenoid hypoplasia, also known as glenoid dysplasia and dysplasia of the scapular neck, is a failure of ossification of the posteroinferior two-thirds of the glenoid. Once thought to be a rare condition, more recent studies have shown that the incidence of glenoid hypoplasia ranges from 18% to 35%.
How do SLAP lesions occur?
A SLAP lesion is mainly caused by a fall on an outstretched arm where there is an important superior compression on the labrum which causes a tear of the labrum. A typical symptom is intermittent pain that also occurs in overhead movements.
What is a Bankart lesion in shoulder?
One of the most common labral injuries is known as a Bankart lesion. This condition occurs when the labrum pulls off the front of the socket. This occurs most often when the shoulder dislocates. If a Bankart tear doesn’t heal properly, it can cause future dislocations, instability, weakness and pain.
How do you fix a labral tear in the shoulder?
SLAP tears are usually treated with rest, anti-inflammatory medications and, in some cases, an in-office cortisone injection. This is followed by gradual stretching of the shoulder, initially with a physical therapist, for six weeks to two months.
What happens if a shoulder labral tear goes untreated?
If left untreated, this may lead to chronic or recurrent shoulder instability, pain, and weakness.
Is a labrum tear serious?
The labrum runs from there around the joint, both in an anterior and in a posterior direction. Due to injury in this area where the biceps tendon attaches, the labrum also can get injured. The injury in this area can be mild or it can be severe.
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.
What is HAGL?
Humeral Avulsion of the Glenohumeral Ligament (HAGL) is an injury to the inferior glenohumeral ligament causing instability and/or pain and a missed cause of recurrent shoulder instability.
What is a HAGL lesion?
Humeral avulsion of the glenohumeral ligament (HAGL) is a lesion associated with anterior shoulder instability. Although uncommon, HAGL lesions are a significant contributor to shoulder pain and dysfunction and, if missed, can even be a cause of failed Bankart repair.
What is the difference between Hill Sachs and Bankart lesion?
Anterior dislocation causes a typical impression fracture on the posterior humeral head, known as a HillSachs lesion. The labrum or the glenoid itself may also be damaged; these injuries are known as Bankart lesions.
What is a SLAP tear?
A SLAP tear is an injury to the labrum of the shoulder, which is the ring of cartilage that surrounds the socket of the shoulder joint.
Is a Bankart lesion painful?
A bony Bankart lesion shows besides the soft tissue damage also a fracture of the anteroinferior glenoid rim. Patients with a Bankart lesion are recognized by shoulder pain which is not localized in a specific point and the pain gets worse when the arm is held behind the back.
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 a Hill-Sachs lesion require surgery?
A Hill-Sachs defect that causes the ball to move abnormally within the socket is said to be engaging, and these engaging Hill-Sachs injuries usually require surgical treatment.
What causes Hill-Sachs lesions?
A Hill-Sachs lesion only occurs when there is forward dislocation of the shoulder. View a detailed BodyMap of the shoulder. A dislocation injury can happen in sports, in a fall, or in reaching or pulling with your arm extended. Shoulders are the most commonly dislocated major joint .
Where is glenoid fossa?
shoulder joint The glenoid fossa is the socket of the shoulder joint. This part of the shoulder is a ball and socket joint. The head of the Humerus fits into the Glenoid fossa, though it is a shallow socket.
What is a hypoplastic labrum?
Labrum hypoplasia was defined as a labrum width at the 12 o’clock position of <4mm and normal labrum was defined as labrum width between 4 and 7mm. Patients with hypoplastic labrum were matched 1:1 by age and BMI to patients with normal labrum width.
What is glenoid Retroversion?
Glenoid retroversion is the abnormal posterior angulation of the articular surface of the glenoid of the scapula and is of importance as it predisposes to posterior glenohumeral instability and tears of the posterior labrum.
Where do you feel pain with a SLAP tear?
Common SLAP tear symptoms include: Shoulder pain that can be a persistent dull ache or a sharp pain deep in your shoulder. Shoulder pain in certain positions, like raising your arm or stretching your arm behind your head. Shoulder pain when you do certain things, like throwing a ball or reaching overhead.
Can a slap tear in shoulder heal on its own?
SLAP tears are often painful and can cause clicking in the shoulder. They often occur as a result of a jarring motion of the arm. Unfortunately, SLAP tears do not heal on their own and usually require surgery to allow them to heal properly.
Can I exercise with a SLAP tear?
Symptoms of a labrum injury can range from a minor annoyance to debilitating. In many people it severely limits overhead activity and the ability to carry out routine daily activities. The right exercises can help. For the best results, exercise 3 to 5 times per week.
What is the name of the socket that the head of the humerus rests inside of?
The head, or ball of the humerus, fits into a shallow socket of the shoulder blade, called the glenoid.
How long does it take a Bankart lesion to heal?
It is usually estimated that it will take at least 4-6 months to feel as though you have completely regained the use of your arm. Some cases may take as long as 9-12 months to make a full recovery.
