Supraspinatus tendonitis is not a life-threatening condition; however, if left undiagnosed or untreated, it can cause inflammation and pain in the shoulder blade area, leading to discomfort and reduced quality of daily life.
Definition: Supraspinatus tendonitis
The supraspinatus tendon is part of the rotator cuff muscle group, which includes the supraspinatus, infraspinatus, subscapularis, and teres minor muscles. This muscle group plays a crucial role in shoulder rotation and helps maintain the stability and balance of the humeral head on the shoulder blade. The supraspinatus tendon is located beneath the acromion and endures significant pressure during shoulder movement, making it more susceptible to injury than other tendons in the rotator cuff.
Supraspinatus tendonitis refers to the symptoms associated with degeneration or overuse of the supraspinatus tendon, often described as shoulder pain due to repetitive strain. Although the exact pathological mechanism of tendonitis has not been clearly defined, most studies in pathology, biomechanics, and molecular biology suggest that the condition is primarily degenerative rather than inflammatory. Nevertheless, the term “tendonitis” continues to be widely used in both clinical practice and medical literature.
Causes of supraspinatus tendonitis
Supraspinatus tendonitis often occurs in athletes such as basketball players, swimmers, and gymnasts who frequently move their shoulders, causing the rotator cuff tendon to rub against the acromion and become inflamed. It may also result from trauma or impact that injures the tendon as it passes beneath the acromion.
Other causes include bone spurs or calcification compressing the tendon, imbalance in shoulder movement, aging, diabetes, dyslipidemia, and genetic factors.
Common symptoms of supraspinatus tendonitis
Supraspinatus tendonitis causes pain and stiffness similar to other tendon inflammations. When the condition becomes more persistent, it presents with the following specific symptoms:
- Shoulder pain when performing overhead movements such as dressing, combing hair, or reaching for objects above head level
- Pain on the outer side of the shoulder near the deltoid muscle
- Pain that worsens at night
- Sharp pain when lying on the affected shoulder
Supraspinatus tendonitis can lead to complications such as arthritis, joint stiffness, or rotator cuff tears, making treatment more difficult. Therefore, if shoulder pain or inflammation persists for several weeks, patients should visit a medical facility for timely examination and treatment.
Treatment methods for supraspinatus tendonitis
When symptoms of supraspinatus tendonitis appear, patients should promptly visit a reputable medical facility for examination and diagnosis by a specialist. Depending on the severity of inflammation, the doctor will recommend the most appropriate treatment approach, typically including two main methods:
Conservative treatment
Most patients with early-stage supraspinatus tendonitis can be successfully treated with conservative methods, including rest, appropriate lifestyle adjustments, rehabilitation exercises, and the use of anti-inflammatory medications as prescribed by a doctor. Patients who cannot adhere to the treatment regimen due to occupational demands may experience worsening pain and will be advised to consider surgical intervention.
Surgical treatment
If conservative treatment shows no improvement after 3–6 months and the inflammation causes persistent pain that limits daily activities, exercise, or work, doctors may recommend surgery based on the patient’s specific condition to prevent complications associated with supraspinatus tendonitis.
After surgery, patients can return to normal work and physical activity once full shoulder range of motion, muscle strength, and joint stability are restored. However, recovery time varies depending on age, treatment method, and the patient’s commitment to rehabilitation.

How to prevent supraspinatus tendonitis
Preventing supraspinatus tendonitis is essential to protect shoulder health and avoid injuries or complications. The condition can be prevented through the following measures:
Maintain proper posture during work and exercise: For athletes, correct posture during training and competition helps prevent supraspinatus tendonitis and other shoulder injuries.
Practice correct techniques: Perform exercises and sports movements properly to reduce stress on the tendons. It is advisable to consult experts or follow the guidance of professional trainers when engaging in any sport.
Adopt a healthy lifestyle: Maintain a balanced diet rich in calcium, avoid alcohol and stimulants, and ensure a well-balanced routine of work, rest, and physical activity.
