Introduction After a vaccination, patients frequently have clinical symptoms of pain and swelling over the injection area which usually resolve 2–3 days after the injection. If the symptoms do not improve, a shoulder injury related to vaccine administration (SIRVA) will be considered, perhaps related to an improper injection technique. Herein we report our first case of a SIRVA after a Sinovac COVID-19 vaccination which occurred due to deep penetration and direction of the needle. The clinical symptoms of the patient improved after treatment with combined oral non-steroidal anti-inflammatory drugs and a short course of intravenous antibiotic. Case presentation A 52-year-old Thai male without prior shoulder pain had a Sinovac COVID-19 vaccination at his right shoulder. The injection was given by a nurse using a 27-gauge needle, 1.5 inches in length. The injection landmark was 3 finger breadths below the midlateral edge of the acromial process. The direction of the needle was 45° to the skin cephalad. Three days after receiving the vaccine the patient began to have right shoulder pain with limited range of motion and acute fever. He was admitted for medical treatment which his clinical symptoms gradually improved. Conclusion We report a case of subacromial-subcoracoid-subdeltoid bursitis following a Sinovac COVID-19 vaccine injection. This condition is rare, and usually related to an incorrect vaccination technique. To avoid this complication, nurses should identify the correct landmark, use an appropriate needle length, and point the needle in the correct direction.
Background: A shoulder injury related to vaccine administration (SIRVA) is a vaccination complication that can affect daily life activities. To date, there have been no case series of patients diagnosed as SIRVA following a COVID-19 vaccination. We offer a series of seven SIRVA cases including clinical presentations, investigations and treatment outcomes. Methods: A retrospective chart review was performed for seven patients who developed SIRVA following a COVID-19 vaccination between April 2021 and October 2021. All patients had no prior shoulder pain before their vaccination and then developed shoulder pain within a few days following the vaccination, which did not spontaneously improve within 1 week. Results: Four of the seven patients were male, and the average age was 62.29 ± 7.76 years. The average body mass index was 25.1 ± 2.2 kg/m2. In all cases, the cause of the SIRVA was from an incorrect COVID-19 vaccine administration technique. Two patients developed shoulder pain immediately following the injection, one patient about 3 h after the injection, and the other four patients within the next few days. Two of the seven patients visited the orthopedic clinic after the persistent shoulder pain for 3 and 4 days and the other five patients 1–9 weeks following their injections. One of the seven patients was treated with combined intravenous antibiotic and oral non-steroidal anti-inflammatory drug (NSAID) because septic arthritis of the shoulder could not initially be ruled out, and recovered within 2 weeks. The other six patients had shoulder pain without acute fever, and five of them were treated with only oral prednisolone 30 mg/day for 5–10 days, following which the pain improved and they all could return to normal activities within 14 days, with no side effects from the prednisolone such as stomachache, nausea, vomiting, headache, or dizziness. Discussion and conclusion: In our series, the most common cause of SIRVA was an incorrect vaccination technique. Most patients responded well to oral NSAIDs or oral prednisolone. Clinical relevance: All SIRVAs were from an incorrect injection technique and not actually the vaccination, so our series highlights the importance of ensuring all vaccinators understand the importance of taking proper care with the injection technique. Additionally, most of our patients with SIRVA from a COVID-19 injection responded well to oral prednisolone (30 mg/day). If there are no contraindications, we suggest this as the first line treatment for COVID-19-related SIRVA.
Background Varus ankle osteoarthritis is classified using only weightbearing anteroposterior ankle radiographs; however, sagittal ankle alignment may also affect the position and extent of joint space obliteration. We hypothesized that the sagittal alignment of the ankle may also affect the position and extent of joint space obliteration visible on the coronal section; therefore, we identified the sites of joint space obliteration in patients with stage 3 varus ankle osteoarthritis for comparison with the sites observed on simulated weightbearing computed tomography and investigated the effects of anterior and posterior ankle subluxation. Methods Simulated weightbearing computed tomography scans of 83 ft with varus ankle osteoarthritis (26 stage 3a, 57 stage 3b) were performed to check for joint space obliteration in the ankle. Further classification as exhibiting either anterior, posterior, or no subluxation on weightbearing lateral radiographs was performed. Results Anterior, posterior, and no subluxation was seen in 5, 9, and 12 ankles among the 26 classified as stage 3a, respectively, and in 22, 12, and 23 ankles among the 57 classified as stage 3b, respectively. The mean tibial lateral surface angle on weightbearing lateral radiographs in stage 3a ankles was 75.6, 83.3, and 80.3 degrees in the anterior, posterior, and no subluxation groups, respectively; and 75.5, 86.6, and 82.7 degrees in stage 3b ankles (p < .05). In stage 3b ankles, widespread joint space obliteration was observed at the anterior distal articular surface of the tibia in all 22 ankles with anterior subluxation and at the posterior distal articular surface of the tibia in all 12 ankles with posterior subluxation. Conclusions Simulated weightbearing computed tomography revealed joint space obliteration at the anterior distal articular surface of the tibia in stage 3b ankles with anterior subluxation and at the posterior side in stage 3a and 3b ankles with posterior subluxation. In some patients with stage 3 varus ankle osteoarthritis, the obliteration of the joint space is difficult to evaluate accurately using only weightbearing anteroposterior radiographs; weightbearing lateral radiographs should also be performed.
Avulsion anterior cruciate ligament injuries are more common in pediatric patients. There are several methods of fixation available for these injuries (tibial intercondylar eminence fractures), such as the pullout suture technique, screw fixation, and suture anchor fixation. Currently, a pullout technique is widely used for fixation. We purpose a pullout technique method using a modified No. 16 intravenous catheter needle to suture the anterior cruciate ligament fiber instead of a suture hook or suture passer. We also use one anterior tibial tunnel for this arthroscopic pullout fixation technique to decrease the incidence of physeal injury in pediatric patients by using many tibial tunnels.
