SIRVA (Shoulder Injury Related to Vaccine Administration) following mRNA COVID-19 Vaccination: Case discussion and literature review

Shoulder Injury Related to Vaccine Administration (SIRVA) Following COVID-19 Vaccination: Correlating MRI Findings with Patient Demographics

OBJECTIVES

Shoulder injury related to vaccine administration (SIRVA), previously observed with influenza vaccines, has gained clinical significance with widespread COVID-19 vaccination. However, few studies correlate vaccine types and demographic factors with the MRI findings of SIRVA. This study aimed to evaluate MRI findings of SIRVA following COVID-19 vaccination and assess associations with vaccine type and patient characteristics.

METHODS

A retrospective cohort study was conducted on 35 patients with new-onset shoulder complaints within six weeks of COVID-19 vaccination between May 2021 and May 2022. MRI findings suggestive of SIRVA were reviewed, including subacromial bursitis, rotator cuff tears, and adhesive capsulitis. Demographic data, vaccine type, clinical symptoms, and treatments were collected. Follow-up interviews (1-30 September 2024) assessed symptom persistence and vaccine hesitancy. Descriptive statistics and Chi-square tests were used to explore associations.

RESULTS

Of the 35 patients (mean age 53.6 ± 9.0 years; 54.3% female), subacromial bursitis was the most common MRI finding (89.5%), followed by tendonitis (47.4%) and adhesive capsulitis (36.8%). Tendonitis correlated with older age (p = 0.024) and AstraZeneca vaccination (p = 0.033). Subacromial bursitis was linked to female sex (p = 0.013) and higher BMI (p = 0.023). Adhesive capsulitis was associated with receiving the Sinopharm vaccine (p = 0.029). Persistent symptoms (22.9%) were more common in younger patients, women, and those with right-sided injections.

CONCLUSIONS

SIRVA following COVID-19 vaccination showed different MRI patterns associated with female sex, higher BMI, and vaccine type. Awareness of these patterns may expedite recognition of COVID-19-associated SIRVA in routine practice.

Dynamic ultrasound evaluation and treatment of subcoracoid bursitis after HPV vaccination: a case of shoulder injury related to vaccine administration (SIRVA)

Shoulder Injury Related to Vaccine Administration (SIRVA) is a complication caused by improperly administered vaccinations. It triggers an inflammatory cascade that damages shoulder structures, resulting in prolonged shoulder pain and restricted range of motion. Common diagnoses in SIRVA patients include shoulder bursitis (all classified as subacromial bursitis), adhesive capsulitis, and rotator cuff injuries such as tears or tendinopathy. Less frequent diagnoses include biceps tenosynovitis, shoulder synovitis, intramuscular hematoma, and polymyalgia rheumatica or polymyalgia rheumatica-like syndrome. We present a case of SIRVA with prominent subcoracoid bursitis, confirmed via ultrasound. Ultrasound plays a critical role in static and dynamic assessments, providing accurate diagnoses and valuable guidance for identifying associated pathologies and managing SIRVA.

An analysis of reported cases shoulder injury related to vaccine administration of after COVID-19 vaccination

To prevent COVID-19, the COVID-19 vaccine has been widely administered worldwide, but various complications accompany this vaccine. The aim of this study was to investigate the demographic patterns, clinical features, diagnostic findings, and treatment outcomes associated with shoulder injury related to vaccine administration (SIRVA). This study examined 22 patients with SIRVA following COVID-19 vaccination from the Web of Science (WOS) and PubMed databases. The patients were categorized based on sex, age, type of COVID-19 vaccine received, dose administered, latency of symptom onset, and the presence of specific clinical manifestations. Patients, evenly distributed by sex (12 females, 10 males), and aged 21 to 84 years (mean age 46.6), were analyzed. SIRVA cases were reported across all age groups. The Pfizer - BioNTech COVID-19 vaccine had the highest incidence (n = 8), followed by the Oxford/AstraZeneca COVID-19 vaccine (n = 4). Symptoms, primarily shoulder pain (n = 22) and shoulder mobility disorders (n = 18), occurred within three days post-vaccination. Some patients also reported shoulder swelling (n = 5) and fever (n = 2). Imaging revealed nonspecific X-ray findings, supraspinatus tendon calcification (n = 2), and shoulder edema and inflammation on MRI (n = 12). This study provides insights into the clinical aspects of SIRVA related to COVID-19 vaccination. Recognition and appropriate management of these complications are crucial for optimal patient outcomes.

Common characteristics of shoulder injury related to vaccine administration following COVID-19 vaccination: a comprehensive systematic review

BACKGROUND

The pathogenesis of shoulder injury related to vaccine administration (SIRVA) is incompletely understood, but it is postulated to be an immune-mediated inflammatory response to a vaccine antigen, leading to shoulder pain and dysfunction. The purpose of this investigation is to systematically review the literature related to SIRVA specifically after the COVID-19 vaccination by describing the diagnostic and clinical characteristics, diagnoses associated with SIRVA, and incidence between vaccine types.

METHODS

A systematic review was performed to identify level I to IV studies and case descriptions of shoulder pain occurring after COVID-19 vaccination. To confirm that no studies were missing from the systematic review, references of studies from the initial search were scanned for additional relevant studies.

RESULTS

A total of 22 studies, comprised of 81 patients, were identified meeting the inclusion/exclusion criteria. Reports were most commonly published from countries in Asia (53.1%; n = 43/81). The most commonly described vaccines were Oxford-AstraZeneca at 37.0% (n = 30/81) and Pfizer-BioNTech at 33.3% (n = 27/81). Symptoms occurred most commonly after at least 72 hours of administration (30.9%, n = 25/81). One hundred percent of patients (n = 81/81) described pain as an associated symptom and 90.1% of patients (n = 73/81) described multiple symptoms. The diagnostic modalities utilized to identify a specific pathology consisted of magnetic resonance imaging (55.6%; n = 45/81), ultrasound (28.4; n = 23/81), radiograph (25.9%; n = 21/81), and computed tomography (4.9%; 4/81). Nearly a third of patients (32.1%; n = 26/81) were diagnosed with bursitis, while 22 (27.2%) were diagnosed with adhesive capsulitis, 17 (21.0%) with either rotator cuff tear or tendinopathy, and 14 (17.3%) with polymyalgia rheumatica or polymyalgia rheumatica-like syndrome. The 2 most common treatment options were physical therapy (34.6%; n = 28/81) and nonsteroidal anti-inflammatory medications (33.3%; 27/81). The majority of SIRVA cases (52.1%; n = 38/73) completely resolved within a few weeks to months.

CONCLUSION

Despite the limited quality and lack of large-scale studies, it is important for providers to recognize SIRVA as a potential risk factor as the number of patients receiving COVID-19 vaccinations and boosters continues to rise.

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.

Chronic stage magnetic resonance imaging findings in patients with shoulder injury related to vaccine administration (SIRVA)

PURPOSE

Identify chronic shoulder MRI findings in patients with known shoulder injury related to vaccine administration (SIRVA).

MATERIALS AND METHODS

Two fellowship-trained musculoskeletal radiologists retrospectively reviewed the MRI of nine patients with clinically established SIRVA. MRI was performed at least 4 weeks after vaccination and included intravenous contrast-enhanced sequences. MRI was reviewed for the presence of erosions, tendonitis, capsulitis, synovitis, bone marrow oedema, joint effusion, bursitis, cartilage defects, rotator cuff lesions, and lymphadenopathy. The number and location of focal lesions were recorded.

RESULTS

Erosions of the greater tuberosity were present in 8/9 (89%), tendonitis of the infraspinatus muscle tendon in 7/9 (78%), capsulitis, synovitis, and bone marrow oedema in 5/9 (56%) cases, respectively. Effusion was found in three, and subdeltoid bursitis, rotator cuff lesions as well as cartilage defects in one patient, respectively. None of our included subjects showed axillary lymphadenopathy.

CONCLUSION

In this case series, greater humeral tuberosity erosions, infraspinatus muscle tendonitis, capsulitis, synovitis, and bone marrow oedema were common MRI findings in chronic SIRVA.

Establishment of prediction equations for subcutaneous tissue thickness in two representative intramuscular deltoid injections

This study clarifies the predicted subcutaneous shoulder depth and investigates the safety of the conventional (three-finger breadth method) and new (axillary method) intramuscular injection methods. The anatomical features of 245 volunteers who received the COVID-19 vaccination via the conventional method were investigated at the injection site (T point) and the hypothetical injection site using the new method (A point) via ultrasonography. The body mass index (BMI) and subcutaneous thickness at the T point (men: r = 0.75; women: r = 0.45) and the A point (men: r = 0.81; women: r = 0.55) were positively correlated. The upper arm circumference and subcutaneous thickness at the T point (r = 0.51) and the A point (r = 0.58) were correlated in women. Formulas to predict subcutaneous thickness using BMI and upper arm circumference were established: predicted subcutaneous thickness at the A point = 0.62 × BMI - 7.7 mm (R² = 0.66) in men and 0.658 × BMI - 5.5 mm (R² = 0.31) in women. This study demonstrates safe intramuscular injection sites and their depth.

Refractory shoulder injury related to vaccine administration: correlation with culture presence of Cutibacterium acnes

Background

Shoulder pain following intramuscular administration of vaccine is common. However, a small number of patients experience prolonged pain and dysfunction atypical to normal transient postvaccination shoulder pain. Shoulder Injury Related to Vaccine Administration (SIRVA) remains incompletely understood, whether a robust immune response to vaccine antigen or inappropriate injection technique with needle placement in synovial or bursal tissue, or some combination of the two. Symptoms overlap with those of Cutibacterium acnes (C. acnes) infection but the relationship between the two, if any, has not been evaluated.

Methods

Clinical case files were reviewed for 3 cases of SIRVA with positive cultures for C. acnes were reviewed. Presentation, treatment, and clinical outcomes were compared.

Results

In all cases, patients were thin (body mass index < 23), females, who had high injection placement of a vaccine, all patients had positive magnetic resonance imaging findings of increased signal in the subacromial bursa, and/or greater tuberosity. All patients underwent arthroscopic débridement and culture harvest and cultures were positive for C. acnes. A combination of oral and intravenous antibiotics was used, and all patients demonstrated clinical improvement from the preoperative state.

Discussion

This case series presents 3 patients with refractory SIRVA who ultimately underwent arthroscopic irrigation and débridement with culture biopsy. Each case had culture results positive for C. acnes and all responded, at least partially, to arthroscopic débridement and intravenous antibiotic therapy. The purpose of this manuscript is to raise awareness of potential coexistence of SIRVA and C. acnes which may be of assistance to surgeons treating refractory cases of SIRVA.

Acute myopericarditis and left shoulder capsulitis following second dose of mRNA SARS-CoV-2 Moderna vaccination

Vaccination against mRNA SARS-CoV-2 has been administered on a very large scale and various side effects have been described. The increased risk of myopericarditis is known, and only a few cases of shoulder capsulitis have been reported after vaccination. These two pathologies have never been reported in the same patient after vaccination. Our article presents the history of a man in his 40s who presented with myopericarditis a few days after vaccination against SARS-CoV-2 with mRNA(Messenger RNA) Moderna® vaccine and who at the same time developed shoulder capsulitis. His cardiovascular symptoms resolved rapidly, and his shoulder symptoms improved/resolved within 1 year. This case should make physicians aware of the possibility of several concomitant side effects following vaccination against SARS-CoV-2.

Shoulder injury following COVID-19 vaccine administration: a case series and proposed diagnostic algorithm

BACKGROUND

Shoulder Injury Related to Vaccine Administration (SIRVA) is a preventable adverse event following incorrect vaccine administration, which can result in significant long-term morbidity. There has been a notable surge in reported cases of SIRVA as a rapid national population-based COVID-19 immunization program has been rolled out across Australia.

METHODS

Surveillance of Adverse Events Following Vaccination in the Community (SAEFVIC) in Victoria identified 221 suspected cases of SIRVA following the commencement of the COVID-19 vaccination program, reported between February 2021 and February 2022. This review describes the clinical features and outcomes of SIRVA in this population. Additionally, a suggested diagnostic algorithm is proposed, in order to facilitate early recognition and management of SIRVA.

RESULTS

151 cases were confirmed as SIRVA, with 49.0% having received vaccines at state vaccination centers. 75.5% were suspected incorrect administration site, with most patients experiencing shoulder pain and restricted movement within 24 hours of vaccination, lasting on average 3 months.

CONCLUSION

Improved awareness and education regarding SIRVA is imperative in a pandemic vaccine roll-out. The development of a structured framework for evaluating and managing suspected SIRVA will aid in timely diagnosis and treatment, essential to mitigate potential long-term complications.

Shoulder Pain and Dysfunction After Vaccination: A Systematic Review

BACKGROUND

Persistent shoulder pain and dysfunction after vaccination are relatively rare but well-known complications after inoculations into the deltoid muscle. The term SIRVA (shoulder injury related to vaccine administration) is frequently used to encompass many of these occurrences; however, multiple distinct pathologies with similar presentations have been reported after vaccination. We performed a systematic review of the literature on vaccine-related shoulder injuries to help guide practitioners in appropriate workup and treatment based on specific diagnoses.

METHODS

PubMed was used to search for combinations of multiple keywords (including vaccine, immunization, SIRVA, injury, inflammation, bursitis, Parsonage-Turner syndrome, and neuritis), and all references of each potential article were reviewed. A total of 56 articles were included. Patient demographics, vaccine information, presentation, diagnostic studies, treatment, and outcomes were recorded.

RESULTS

Diagnoses were divided into 3 categories: (1) local inflammatory reaction (SIRVA), (2) brachial neuritis, and (3) direct nerve injury. The included articles reported on 57 cases of SIRVA, 18 of brachial neuritis, and 4 of direct nerve injury. The diagnoses reported for the SIRVA cases included frozen shoulder, pseudoseptic arthritis, subacromial bursitis, rotator cuff injury, and lytic lesions of the humeral head. Various treatments were used, and most patients had resolution of symptoms with conservative treatment including physical therapy, analgesics, and/or corticosteroid injections. Advanced imaging rarely provided information that affected treatment. The brachial neuritis and direct nerve injury cases were typically confirmed with electromyography/nerve conduction studies. Treatment of these 2 categories was nonoperative in all cases, typically with analgesics and/or corticosteroids, and most patients had symptomatic improvement after a few months, with most patients regaining strength. However, some (1 of 3 patients with brachial neuritis and >1 year of follow-up and 2 of 4 patients with direct injury) had residual weakness.

CONCLUSIONS

Medical professionals should be aware of the various pathologies that can lead to prolonged shoulder pain after vaccination. Fortunately, most of these conditions can be treated successfully with nonoperative modalities, although differentiating among the diagnoses can help guide treatment, as some likely benefit from systemic corticosteroids or localized corticosteroid injections. Outcomes for most patients have been good, with the majority recovering without residual pain or deficits.

Shoulder injury related to vaccine administration (SIRVA) after COVID-19 vaccination

OBJECTIVE

The global fight against COVID-19 has required mass vaccination clinics as well as mass recruitment of personnel, including many who may not regularly administer intramuscular deltoid immunizations, potentially increasing the incidence of improper intramuscular injection. Shoulder injury related to vaccine administration (SIRVA) is a well-described, preventable injury resulting from improper injection into anatomic structures adjacent to the deltoid muscle leading to mechanical and chemical trauma augmented by an inflammatory immune response to the vaccine and/or adjuvants. SIRVA is best described in the setting of influenza vaccination, and little is known about it as it pertains to COVID-19 vaccination. This study aims to describe SIRVA in the current pandemic, increase clinician awareness, and offer considerations for prevention.

METHODS

To identify clinical characteristics of patients with post-COVID-19-vaccination shoulder injuries, we performed a systematic review of the cases of vaccination-related shoulder injuries reported in the literature and conducted a review of the public Vaccine Adverse Event Reporting System (VAERS).

RESULTS

We identified 305 cases of SIRVA in the VAERS database and 28 cases of SIRVA in the setting of COVID-19 vaccination from the literature (n = 333). Patients had a mean age of 51.8 years and a median of 51.5 (range: 19-90) years. Of these, 76.3% were female and 23.7% male. Most patients sought medical evaluation with 54 of the 305 VAERS cases reporting utilizing emergency services. Of patients with imaging-confirmed SIRVA (n = 95), the most common diagnoses were adhesive capsulitis and bursitis, and the most common symptoms were pain (97.7%) and limited range of motion (68.1%). Most patients reported requiring treatment with the majority receiving physical therapy (56.3%), followed by cortisone injection (34.4%). Other modalities used were non-steroidal anti-inflammatory drugs, oral steroids, and surgery. Only 5 patients from this group reported recovery while 60 stated they had not yet recovered. Of those, 23.3% reported disability.

CONCLUSION

SIRVA should be regarded as an under-reported, significant cause of post-vaccination morbidity. In the setting of COVID-19 mass vaccination, clinicians must be aware of signs and symptoms of SIRVA as well as appropriate diagnostic modalities and treatment options. Additionally, standardization and proper education regarding injection technique and appropriate needle length is imperative to reducing harm.
