Adhesive capsulitis following COVID-19 vaccination: a case report and review of literature.

Shoulder injury related to vaccine administration (SIRVA) has been frequently reported adverse event following COVID-19 vaccination. Multiple studies have reported various injuries including subacromial bursitis, rotator cuff tears, nerve injury, and most commonly, adhesive capsulitis. Adhesive capsulitis is defined as an inflammatory disease of the joint capsule characterized by pain and stiffness. Herein, we present a case of a 38-year-old female, known to have uncontrolled diabetes mellites and asthma, presented to upper extremity orthopedic clinic complaining of 6 months history of left shoulder pain and limited range of motion following COVID-19 vaccination administration. Clinical examination and radiological studies were consistent with adhesive capsulitis, the patient was then referred for intensive rehabilitation program that provided adequate response. In conclusion, the main etiology of SIRVA has been attributed to suboptimal injection technique, a standardized definition, implementation of safe vaccines injection protocols, and further education and awareness of SIRVA is needed to healthcare practitioners to allow better understanding and prevention.
