Influenza vaccine related periostitis: A case report of a rare complication

As social distancing guidelines continue to diminish across the country, viral pathogens that were once absent during the COVID-19 pandemic, such as influenza and RSV, have once again become prominent. Although serious side effects of vaccinations are rare, local complications of bursitis and skin and soft tissue infections are well-documented in the literature. We present a case of 1 such rare side effect: influenza vaccine related periostitis. A 39-year-old male patient presented with left shoulder pain which developed 2 days after an influenza vaccination administered to the left deltoid. His symptoms were persistent despite rest and 1 week trial of NSAIDs. MRI imaging demonstrated marrow edema and a periosteal reaction of the left shoulder. Overall, vaccine induced periostitis is poorly documented in the literature and the pathophysiology has not been fully characterized. Further research is crucial to identify patient specific risk factors and to raise awareness of this rare complication to promote swift diagnosis and effective treatment.

Proximal Hamstring Repair With All-Suture Anchors and an Accelerated Rehabilitation and Bracing Protocol Demonstrates Good Outcomes at 1-Year Follow-Up

Purpose

To evaluate patient-reported outcomes and risk for rerupture after surgical treatment of proximal hamstring tendon ruptures using all-suture anchors and a unique postoperative bracing strategy.

Methods

A retrospective review of a prospectively collected database was conducted of patients undergoing proximal hamstring repair or reconstruction from 2020 to 2022 at a tertiary, academic institution. Patients were included if they reached minimum 1-year follow-up and completed postoperative patient-reported outcomes. The surgical protocol for proximal hamstring repairs included all-suture anchors placed either in an open or endoscopic fashion in the ischial tuberosity. After surgery, all patients underwent an accelerated rehabilitation protocol, including 6 weeks touchdown weight-bearing in a hinged knee brace locked in extension for ambulation, allowing passive knee flexion to 90° while seated. Descriptive statistics were used to analyze the data.

Results

Twenty-one patients were included (mean age 50.4 ± 9.5 years, body mass index 24.4 ± 3.5, 66.7% female). Lower Extremity Functional Scale score achieved postoperatively was 74.2 ± 7.5 (out of 80). Patients had minimal pain (mean visual analog scale pain score of 0.9 ± 1.2). 61.9% of patients were able to return to the same level of activity after based on Tegner score by 1 year. Postoperative Single Assessment Numeric Evaluation activity of daily living was 94.3 ± 8.3, and Single Assessment Numeric Evaluation Sports was 82.3 ± 19.0. Mean Short Form Survey (SF-12) postoperative scores were 51.6 ± 6.8 for SF-12 Physical Component Score and 53.9 ± 9.7 for Mental Component Score. 95.2% (20 of 21) patients were satisfied with their outcome. There were no reruptures, infections, or reoperations. One patient of 21 (4.8%) incurred a postoperative deep venous thrombosis, which was treated with therapeutic anticoagulation for 3 months.

Conclusions

All-suture anchors for proximal hamstring repair with a unique accelerated postoperative rehabilitation and bracing protocol result in good outcomes and patient satisfaction with minimal risk of complications.

Does Time to Surgery for Distal Radius Fractures Impact Clinical and Radiographic Outcomes? A Systematic Literature Review

Distal radius fractures are one of the most common upper extremity fractures across all age groups. Although the American Academy of Orthopaedic Surgery (AAOS) Clinical Practice Guidelines have defined recommendations for the treatment of distal radius fractures, the optimal time to surgery was not included. There remains relatively little guidance or consensus regarding the optimal timing of surgical intervention for distal radius fractures and the impact of time to surgery on outcomes. As such, the purpose of this investigation is to systematically review clinical and radiographic outcomes associated with time to surgical management of distal radius fractures.

A 5-Year Update and Comparison of Factors Related to the Sex Diversity of Orthopaedic Residency Programs in the United States

Female physicians have been historically underrepresented in orthopaedic surgery residencies. The purpose of this study was to determine whether sex diversity among orthopaedic residency programs and faculty is associated with an increased number of female residents matriculating into that program. In addition, we sought to analyze female resident matriculation trends in the past 5 years.

Methods

The American Medical Association Fellowship and Residency Electronic Interactive Database was used to identify all allopathic orthopaedic surgery residency programs during the 2021 to 2022 academic year. The number of female residents and interns; the number of female faculty, professors, and associate professors; and the number of women in leadership positions were compared with data from the academic year 2016 to 2017. Continuous data were analyzed with independent t-tests, and significance was set at p < 0.05.

Results

A total of 696 female residents (19.2%) were identified from 3,624 orthopaedic residents, an increase from 13.5% in 2016. Programs in the top quartile of female residents had 3 times the number of female residents per program when compared to other quartiles and almost double the number of female interns per program. Programs in the top quartile of female residents had a significantly greater number of female faculty per program than the lower quartiles; 5.76 vs. 4.18. Compared with 2016 to 2017, there were significant increases in female faculty per program from 2.77 to 4.54 along with female full professors from 0.274 to 0.694. These increases contribute to the overall growth in the number of women in leadership positions per program over the past 5 years to 1.01 from 0.35 (p < 0.001).

Conclusion

In the past 5 years, the percentage of female residents has increased from 13.5% to 19.2%. Furthermore, women make up 22.1% of interns. Orthopaedic surgery residency programs with higher percentages of female faculty had higher numbers of female residents. By encouraging programs to promote female representation within leadership and residents, we may continue to see the gap in orthopaedic sex diversity close.
