Overview
Supraspinatus tendinitis in the left shoulder is characterized by inflammation and pain in the rotator cuff tendon, often leading to significant functional impairment and discomfort 1.Diagnosis
Clinical history and physical examination are crucial, focusing on tenderness over the supraspinatus tendon and pain with abduction and external rotation 1.
No specific diagnostic tests are highlighted; imaging (e.g., MRI) may be considered to rule out other pathologies 1.Management
First-line treatments: Nonsteroidal anti-inflammatory drugs (NSAIDs) and physical therapy aimed at strengthening the rotator cuff and improving shoulder mobility 1.
Adjunctive treatments: Transdermal nitroglycerin (5 mg patch daily for 3 days) shows promise for pain relief, with significant reduction in pain intensity observed 1.Special Populations
Occupational risk: Rockblasters and those exposed to vibration have a higher risk of developing shoulder tendinitis, particularly on the left side (OR 3.33 for left shoulder) 2.Key Recommendations
Consider transdermal nitroglycerin for pain relief in supraspinatus tendinitis, showing significant analgesic effects within 48 hours (Evidence: Strong 1).
Identify and mitigate occupational risk factors, such as vibration exposure, particularly in high-risk professions like rockblasting (Evidence: Moderate 2).
Implement conservative management strategies including NSAIDs and physical therapy to address functional impairment and pain (Evidence: Expert opinion 1).References
