Impingement syndrome: symptoms, diagnosis, and treatment

Impingement syndrome: main aspects

Impingement syndrome, also known as shoulder impingement syndrome, is an injury or inflammation of the shoulder tendons in the area below the scapula. This leads to a reduction in the space between the tendons and the bones of the shoulder joint, which can cause pain and limit movement.

Symptoms of impingement syndrome may include pain in the shoulder area that worsens with arm elevation or shoulder rotation, a feeling of weakness in the shoulder, as well as possible limitation of movement. Diagnosis of this syndrome includes a physical examination, X-ray, magnetic resonance imaging, or ultrasound examination, while treatment may involve physical therapy, the use of anti-inflammatory medications, injections in the shoulder area, or, in rare cases, surgical intervention.

Pathogenesis of Impingement Syndrome

Impingement syndrome is usually associated with compression or irritation of the subscapular nerve in the shoulder girdle area. The main causes include osteophytes on the clavicle, degenerative changes in the shoulder joint, injuries, or inflammatory processes that lead to nerve compression.

In addition, factors that contribute to the development of impingement syndrome may include poor posture, uneven loading of the shoulder joints, as well as professional risks, such as constant movement of the arm in one direction. Effective treatment of impingement syndrome is related to identifying its causes and aimed at eliminating their impact on the shoulder girdle, which helps restore normal joint function and reduce pain syndrome.

  • Compression of the iliac-subscapular nerve: irritation or compression of the nerve in the shoulder girdle area contributes to the development of the syndrome.
  • Osteophytes on the clavicle: abnormal growths of bone tissue on the clavicle can cause pressure on nerve structures.
  • Degenerative changes in the shoulder joint: accumulation of degenerative changes in the shoulder joint can lead to compression of nerve endings.
  • Injuries and inflammatory processes: injuries or inflammation in the shoulder girdle area can be the cause of nerve irritation and the development of the syndrome.
  • Poor posture: incorrect body posture or alignment can create uneven pressure on the shoulder joints, which can ultimately lead to nerve irritation.

Clinical picture of Impingement syndrome

Impingement syndrome is characterized by a variety of symptoms, including shoulder pain, especially when lifting the arm above shoulder level, weakness of the shoulder and neck muscles, as well as numbness and tingling in the arm. Patients may also experience difficulty in shoulder movements, particularly when performing certain actions, such as lifting or rotating.

In addition, the severity of symptoms can range from mild discomfort to intense pain and impaired shoulder function. It is important to consider that the symptoms of impingement syndrome may worsen with head turning or bending, as well as with prolonged positioning in an uncomfortable position, significantly limiting the patient’s usual movements and daily activities.

  • Shoulder pain: a symptom that occurs when raising the arm above shoulder level, sometimes spreading down the arm.
  • Muscle weakness: possible manifestation of weakness in the shoulder and neck muscles, which can lead to reduced strength and coordination of movements.
  • Numbness and tingling in the arm: sometimes numbness, tingling, or burning sensation in the arm is observed, more often in the distribution of the subclavian-suprascapular nerve.
  • Difficulties in movement: patients may experience difficulties in performing shoulder movements, especially with certain movements.
  • Increased symptoms when turning the head: symptoms of Impingement syndrome may worsen when turning the head or bending, causing additional discomfort for the patient.

Approaches to the treatment of Impingement Syndrome

Expert opinion on the treatment of Impingement Syndrome emphasizes the importance of an individual approach to each patient, taking into account the severity of their condition and the peculiarities of the clinical picture. Effective methods may include conservative approaches such as physical therapy, the use of anti-inflammatory medications, and corticosteroid injections to relieve pain and inflammation in the shoulder area.

Some experts note that in cases where conservative methods do not provide adequate relief, surgical intervention may be necessary. Surgery may include decompression of the shoulder joint to reduce pressure on the nerve structures or rehabilitation procedures to restore shoulder function and prevent recurrences of the syndrome.

Methods for diagnosing Impingement Syndrome

To diagnose Impingement Syndrome, a doctor may perform a physical examination that includes an analysis of active shoulder and neck movements, muscle inspection, and testing for strength and sensitivity. Additionally, radiological studies may be requested to assess the condition of the joints, magnetic resonance imaging for detailed examination of structural changes, as well as electromyography to evaluate muscle and nerve function.

Expert opinion emphasizes the need for a comprehensive approach to diagnosing Impingement Syndrome using various examination methods to accurately determine the causes and identify the characteristics of this condition. Diagnosis plays a crucial role in developing an individualized treatment program aimed at improving shoulder function and reducing pain syndrome in the patient.

  • Physical examination: The doctor conducts an analysis and assessment of active movements of the shoulder and neck, studies the muscles for contractions or tenderness, and checks strength and sensitivity in the corresponding area.
  • X-ray: X-ray studies can reveal degenerative changes in the shoulder girdle joints, such as osteophytes or displacements, which may be causing nerve compression.
  • Magnetic Resonance Imaging (MRI): MRI allows for a more detailed examination of tissue structure and detection of pathologies associated with nerve compression in the shoulder area.
  • Electromyography (EMG): EMG is used to assess the function of muscles and nerves, which helps identify changes in impulse conduction and defects in muscle control.
  • Ultrasound examination: Ultrasound can be used to assess the condition of tendons and soft tissues in the shoulder area, identifying inflammatory processes or nerve compression.

Methods of treating Impingement Syndrome

Treatment of Impingement Syndrome often begins with conservative methods such as physical therapy, muscle strengthening, stretching, and the use of medications to relieve inflammation and pain. Physical therapy aims to restore the functions of the shoulder girdle, improve joint mobility, and strengthen muscles, which helps reduce pressure on nerve structures.

In cases where conservative methods do not yield the desired effect, surgical intervention may be required. Surgical treatments for Impingement Syndrome may include arthroscopic decompression, resection of osteophytes, as well as reconstructive surgeries on the shoulder joint to relieve nerve compression and restore normal anatomy. Specialists choose the treatment approach based on the individual characteristics of the patient and the specifics of the condition, aiming for the best outcomes and improved quality of life.

  • Physiotherapy: includes exercises to strengthen the shoulder girdle muscles, stretching to improve joint mobility, and physical therapy methods to reduce pain and inflammation.
  • Medication use: the doctor may prescribe medications to relieve inflammation and pain, such as NSAIDs or muscle relaxants, to ease discomfort in patients with Impingement syndrome.
  • Injections: in some cases, injecting medications directly into the shoulder joint may be recommended to reduce inflammation and pain.
  • Surgical treatment: in cases where conservative methods are ineffective, surgical intervention may be necessary, such as arthroscopic decompression or resection of osteophytes.
  • Post-operative rehabilitation: after surgery, it is important to carry out rehabilitation activities, including physiotherapy and exercises to restore shoulder function and reduce the potential risk of recurrence of Impingement syndrome.

Prevention measures for Impingement Syndrome

To prevent Impingement Syndrome, it is recommended to maintain a proper posture while working at the computer or doing written work, take regular breaks for stretching, and strengthen the muscles of the shoulder girdle and neck with special exercises. It is also important to avoid staying in one position for long periods, especially with raised arms, to prevent strain on the shoulder joint and reduce the risk of nerve compression.

To prevent Impingement Syndrome, it is also advised to lead an active lifestyle, pay attention to posture and workplace ergonomics, and consult a specialist for any unpleasant symptoms in the shoulder girdle or neck, in order to timely identify and treat potential problems.

  • Maintaining proper posture: Adhering to the correct position while working or engaging in physical activities helps reduce strain on the shoulder girdle and lowers the risk of nerve compression.
  • Performing regular exercises: Strengthening the muscles of the shoulder girdle and neck improves joint support, reduces the likelihood of injuries, and alleviates symptoms of Impingement Syndrome.
  • Regular breaks and warm-ups: To prevent strain on joints and muscles, it is recommended to take breaks during long periods of work, as well as perform stretching and warm-up exercises to enhance mobility.
