Shoulder pain is a common complaint that can occur during various activities and have diverse origins. Among the most frequent causes evaluated in consultations is subacromial impingement syndrome.
What is subacromial impingement syndrome and why does it cause shoulder pain?
Subacromial syndrome refers to a set of alterations that affect the structures located in the subacromial space, a key area for shoulder movement. In this context, the tissues involved in raising and stabilizing the arm may be compromised.
Pain appears when that space is reduced or its function is altered, generating frfriction or compression on tendons and other structures. This situation restricts movement and can cause discomfort when performing everyday actions.
How the subacromial space affects the shoulder tendons
When the subacromial space does not function properly, the following occur: changes that directly affect the shoulder tendons:
- Compression is generated on the tendons during arm elevation
- Friction between structures increases during repetitive movements
- Irritation of the soft tissues occurs
- Inflammation may appear in the subacromial area
- The normal sliding capacity of the tendons is reduced.
What is the difference between subacromial impingement and other shoulder injuries?
Subacromial impingement is characterized by a compression mechanism of the shoulder structures, while other injuries may have a different origin, such as tendon ruptures, instability, or more advanced degenerative processes.
Unlike these pathologies, subacromial syndrome is usually associated with functional and mechanical alterations that affect the subacromial space, which influences both the onset of pain and the evolution of symptoms.
What are the symptoms of subacromial syndrome?
Subacromial syndrome usually manifests with discomfort that appears in certain positions or during certain arm movements. These symptoms can vary in intensity and progress gradually if the factors that cause them are not corrected.
Pain when raising the arm, while sleeping, or when making certain movements.
This type of pain usually occurs in specific situations related to shoulder mobility:
- Pain when raising the arm above the head
- Discomfort when performing repetitive movements
- Pain when reaching for objects at a height or backwards
- Difficulty or pain when dressing
- Discomfort when resting the shoulder while sleeping
- Painful sensation on the side of the shoulder
How to tell if shoulder pain could be due to a pinched nerve
Pain related to a subacromial impingement It usually appears gradually and is linked to specific movements. In addition, discomfort often increases with activity and improves with relative rest.
To confirm its origin, it is necessary to assess the location of the pain, the gestures that trigger it, and the associated functional limitation, since these aspects allow it to be differentiated from other causes of shoulder pain.
What causes subacromial syndrome?
Subacromial syndrome can develop due to various causes. causes that affect shoulder mechanics. In many cases, it is not due to a single cause, but to a combination of overload, repetitive use, and changes in the tissues.
Overload, repetitive movements, and rotator cuff injuries
There are several Factors that may favor the appearance of subacromial syndrome:
- Repetitive overhead movements
- Sustained overload in work or sports activities
- Lack of control or coordination in shoulder movement
- Weakness or impairment in the rotator cuff muscles
- Changes in the way the joint moves
- Muscle imbalances that affect shoulder stability
What is the relationship between bursitis, tendinitis, and subacromial syndrome?
Subacromial syndrome is often related to inflammatory processes that affect the structures of this area, such as the subacromial bursa or the rotator cuff tendons. Bursitis and tendinitis can occur as a result of repeated friction or sustained compression in the subacromial space.
These conditions are not always independent, but rather form part of the same process, in which Tissue irritation contributes to the onset of pain and the limitation of movement..
How does a shoulder orthopedic surgeon diagnose subacromial impingement syndrome?
The diagnosis of subacromial syndrome is based on the combination of clinical examination and symptom assessment. Through specific tests and, in some cases, imaging studies, it is possible to identify the origin of the pain and determine the degree of impairment.
What tests help confirm subacromial impingement
For confirm the presence of a subacromial impingement, Various assessment tools are used:
- Physical examination with specific mobility and pain tests
- Clinical tests that reproduce the pinching motion
- Assessment of shoulder strength and control
- Ultrasound to assess tendons and soft tissues
- Magnetic resonance imaging in cases where greater detail is required
- X-ray to analyze the bone anatomy of the shoulder
How to differentiate it from a rotator cuff tear
Subacromial impingement syndrome and rotator cuff tears may share symptoms, but they present differences in their origin and in the way they manifest themselves.
In a pinched nerve, the pain is usually more related to the movement and compression of structures, whereas in a break there may be a more obvious loss of strength.
Clinical examination and imaging tests allow us to distinguish between the two situations, assessing the integrity of the tendons and the degree of functional impairment of the shoulder.
How is subacromial syndrome treated?
He treatment of subacromial syndrome Treatment is usually approached gradually, starting with conservative options aimed at reducing pain and improving shoulder function. The choice of approach depends on the progression of symptoms and the severity of the injury.
Treatment with physiotherapy, medication and injections
The initial approach combines different Measures to control pain and restore movement:
- Physiotherapy aimed at improving shoulder mobility and control
- Exercises to strengthen the rotator cuff and stabilize the joint
- Pain reliever or anti-inflammatory medication to reduce pain
- Modification of activities that generate overload
- Injections in selected cases to reduce inflammation
When to consider surgery if conservative treatment doesn't work
Surgery may be considered when The symptoms persist despite having undergone appropriate conservative treatment. It is also considered in cases where the functional limitation is significant or there are structural alterations that do not respond to other measures.
The surgical indication is established after a complete evaluation., Taking into account the patient's progress, imaging tests, and the impact of the problem on daily activity.
