The shoulder is a joint with a wide range of motion, which also makes it susceptible to various injuries. Among these is a labral tear, which can affect its function and stability.
What is a shoulder labrum tear?
A shoulder labral tear is a This injury occurs when the labrum tears or partially separates from the joint.. The labrum is a ring of tough, flexible tissue that surrounds the shoulder socket and helps to keep the head of the humerus in position.
What role does the labrum play in shoulder stability?
The labrum plays an important role in the stability and function of the joint. Its main functions are:
- Increase the depth of the shoulder socket to improve the fit of the humeral head.
- Promote joint stability, especially during wide movements.
- To serve as an attachment point for ligaments, tendons, and other structures that stabilize the shoulder.
- To help distribute the loads that the joint receives during movement.
What types of labral tears can occur in the shoulder
The labrum lesions They can be classified according to their location and the mechanism that produces them. The main ones include:
- Bankart lesion: It affects the anteroinferior part of the labrum and is usually related to episodes of anterior shoulder dislocation.
- SLAP lesion: It occurs in the upper area of the labrum, where the tendon of the long head of the biceps is inserted.
- Posterior labral tear: It affects the posterior region and can appear due to trauma, repetitive movements, or certain sports activities.
- Degenerative lesions: They develop due to the progressive wear and tear of the tissue and are more frequent with age.
What symptoms does a shoulder labrum tear produce?
The Symptoms of a shoulder labrum tear Symptoms can vary depending on the area and extent of the injury. The most common are pain, clicking or popping sounds when moving the arm, and a feeling of instability, especially during certain movements or exertion.
How to recognize pain, clicking, or an unstable shoulder
These discomforts They can appear in isolation or in combination with each other. Each one usually manifests itself in a different way:
- Pain: It is usually felt on the inside of the shoulder and may increase when raising the arm, performing overhead movements, or exerting force.
- Clicks: Clicks, crackling, or a catching sensation may occur within the joint when moving the shoulder.
- Feeling of instability: The shoulder may feel unsteady or give the impression that it is shifting or may come out of position.
What symptoms appear when throwing, lifting weights, or playing sports?
The activities that require shoulder strength or wide range of motion They can make the symptoms of a labral tear more evident:
- When launching: Pain may occur during movement, along with loss of strength or difficulty throwing with the same accuracy and power.
- When lifting weight: It is common to feel pain, weakness, or discomfort when lifting weight, especially with the arm raised.
- When doing sports: Repetitive movements can cause pain, clicking, loss of performance, or a feeling of insecurity in the shoulder.
When can a shoulder dislocation be associated with a labral injury?
A dislocation can cause a labral tear when the head of the humerus shifts out of position and damages this tissue. This association is especially common in anterior dislocations, which can cause a Bankart lesion.
Following a dislocation, persistent pain or the feeling that the shoulder remains unstable may suggest that there is an associated labral injury.
How is a shoulder labrum tear diagnosed?
The diagnosis of a shoulder labral tear begins with symptom assessment and a physical examination of the joint. Imaging tests then allow us to confirm or specify the type and extent of the injury.
What clinical tests guide the diagnosis of a labral injury?
During the examination, the traumatologist may perform different Tests and movements to check how the shoulder responds. The main aspects that are valued include:
- Shoulder mobility: to detect pain or limitations when moving the arm in different directions.
- Muscle strength: It allows you to check if there is a loss of strength and in which movements it appears.
- Stability tests: They help identify if the shoulder moves more than normal or if there is a feeling of instability.
- Specific maneuvers: Certain movements and positions can reproduce the pain or clicking sounds associated with a labral tear.
What does MRI or MRI arthrography contribute to the shoulder labrum?
Magnetic resonance imaging allows observe the shoulder tissues in detail. In some cases, an MRI arthroscopy is used, which employs contrast dye inside the joint to better visualize certain lesions. These tests allow for:
- Locate the lesion and determine which part of the labrum is affected.
- Assess the type and extent of the break.
- Detect other associated injuries in the tendons, ligaments, or other structures of the shoulder.
- Plan the treatment based on the characteristics of the injury.
What should the orthopedic surgeon assess before deciding on treatment?
The decision about treatment does not depend solely on what the imaging tests show. The traumatologist must assess different factors, as:
- The type, location, and extent of the injury.
- The intensity of the symptoms and how they affect daily activities.
- The degree of stability and mobility of the shoulder.
- The person's age and level of physical activity.
- The presence of other associated injuries.
- The response to previous treatments, such as physiotherapy or rest.
What is the treatment for a shoulder labrum tear?
He treatment of a shoulder labrum tear It depends on the type of injury, the symptoms, and the degree of joint instability. Depending on the case, treatment may involve conservative physiotherapy or surgical repair.
When can a labral tear improve with physiotherapy?
Physiotherapy may be sufficient when The injury does not cause significant instability and the symptoms allow for maintaining good shoulder function.
The treatment aims reduce pain, restore mobility and strengthen muscles which helps to stabilize the joint.
The evolution must be assessed progressively in order to check if the shoulder regains its function and allows you to return to your usual activities without significant discomfort.
When is arthroscopic surgery recommended to repair the labrum?
Surgery may be recommended when There is an injury that causes persistent instability, repeated dislocations, or symptoms that significantly limit activity. and do not improve with conservative treatment.
The repair is usually carried out by shoulder arthroscopy, a minimally invasive technique which allows access to the joint through small incisions and repair of the injured labrum.
