Unplanned Emergency Room Visits following Hip Arthroscopy
Hip arthroscopy is an increasingly common orthopedic procedure. Although the number of reported complications is low, emergency room visits in the early postoperative period do occur. This study aims to evaluate the impact of demographic, insurance, and clinical factors on the likelihood of postoperative emergency department (ED) visits following hip arthroscopy. Through the identification of key risk factors, including insurance status, comorbidities, and procedural specifics, the objective of this study is to inform clinical practices and enhance patient outcomes through targeted risk management. A retrospective review of a multi-center institutional database identified patients who underwent hip arthroscopy between 2014 and 2022. Medical records were analyzed for ED visits within the first 30 postoperative days. Diagnoses leading to ED visits were classified by pathology such as pain, musculoskeletal, or infection. Factors associated with increased odds of ED visits were assessed utilizing a multivariate regression analysis. Of the 879 hip arthroscopies, 3.1% of patients had ED visits within 30 postoperative days. Medicaid patients were 2.88 times more likely to visit the ED (P=0.025). The presence of hypertension (P=0.013) or autoimmune conditions (P=0.041) further increased the odds. The use of a capsular closure technique during surgery reduced ED visits by 69.1% (P=0.026). Following hip arthroscopy, patients with Medicaid insurance, hypertension, and auto-immune disorders are more likely to require ED visits within 30 days. In contrast, the use of a capsular closure technique significantly reduces the likelihood of such visits.

The Relationship Between Patient Demographics, Tear Locations, and Operative Techniques on the Surgical Treatment of Acute Achilles Tendon Ruptures
Achilles tendon ruptures (ATRs) have classically been thought to affect the middle-aged “weekend warrior” participating in basketball, volleyball, soccer, or any ground sport; however, with a more active elderly population, these tears are becoming more common in older patients. We sought to examine the role of demographics, tear location, and operative technique for acute Achilles tendon ruptures treated surgically. A retrospective query was performed to identify patients who presented with Achilles tendon ruptures. Inclusion data were primary end-to-end repairs, augmented repairs with flexor hallucis longus (FHL) transfers, augmented repairs with graft, augmented repairs with both FHL transfer and graft use, isolated FHL transfers, and revision Achilles tendon procedures. Demographics and tear locations were collected and analyzed. Midsubstance tears were the most common tear location occurring in 237 of 286 (82.9%) patients. Distal insertional tears of the Achilles tendon were treated in 35 (12.2%) patients, while 14 (4.9%) patients had a more proximal tear located at the myotendinous junction. Older patients (average age: 53.3±12.5) had significantly more distal insertional tears (p<0.001), while younger patients (average age: 35.1±7.4) presented with significantly more tears at the myotendinous junction (p<0.001). The average BMI was significantly higher (average BMI: 32.2±6.6; p<0.001) in patients with distal insertional tears compared to midsubstance and proximal tears (28.5±4.6 and 28.5±5.3, respectively). There was a higher percentage of diabetic patients who underwent operative treatment for distal insertional tears (20%) compared to midsubstance tears (7.2%). The findings of our study suggest that a subset of patients, particularly those with advanced age and higher BMI, is more likely to present with a distal Achilles tendon rupture. Additionally, patients in our series who had distal tears more commonly required an augmented repair technique. Our results highlight the need for future research to further define the relationship between increasing age and higher BMI patients sustaining distal tears more often than midsubstance tears.

Orthopaedic Trauma Surgeons' Financial Relationships With Industry: An Analysis of the Sunshine Act Reporting of Physician Open Payments From 2014 to 2019
Introduction: Orthopaedic trauma surgeons have an intricate relationship with the medical device industry. In the past decade, legislation has created transparency of monetary exchanges between physicians and industry. In 2013, the Physician Payments Sunshine Act was passed and ultimately led to the creation of the Open Payments Database. The purpose of this study was to evaluate trends in industry payments to orthopaedic trauma surgeons. Methods: A retrospective review of the Centers for Medicare & Medicaid Services' Open Payments Database was conducted for general industry payments to orthopaedic trauma surgeons from 2014 to 2019. Total payments and subtype payments were analyzed for yearly trends. All payments were converted to 2019 US dollars to adjust for inflation. Descriptive statistics included analysis of payments, number of surgeons, types of payments, top contributing companies, and regional comparisons. Trends were assessed through the Jonckheere-Terpstra test. Statistical significance was defined at P < 0.05. Results: From 2014 to 2019, 45,312 individual payments were given to orthopaedic trauma surgeons (N = 3208) accounting for a total of $41,376,397.85 (USD), with a mean of $919.54 per payment. Increased trends were noted for median annual payments, number of payments, and number of surgeons receiving payments. Compared with 2014 ($460.91), median payments were increased by 90.9% in 2016 ($879.85), 102.6% in 2018 ($933.81), and 178.6% in 2019 ($1284.06). Payment subtypes that demonstrated increasing median payments included consulting fees (P = 0.028); education (P < 0.001); entertainment, food, and beverage (P < 0.001); and travel (P = 0.019). Decreases in median payments were seen in royalties (P = 0.044) and grant funding (P < 0.001). Regional comparisons demonstrated increasing trends in median payments in the midwest (P = 0.011), south (P < 0.001), and west (P = 0.003), but not in the northeast (P = 0.081). Discussion: In our study, we found that industry payments to orthopaedic trauma surgeons were increasing markedly between 2014 and 2019, particularly among consulting fees, education, entertainment, food and beverage, and travel.

Review of Industry Payments to General Orthopaedic Surgeons Reported by the Open Payments Database: 2014 to 2019
Introduction: The Physician Payments Sunshine Act was placed into law in 2010 in an effort to create transparency between physicians and industry. Along with many other specialties, orthopaedic surgeons have long worked intimately with medical industry companies. This study aimed to evaluate trends in industry payments to general orthopaedic surgeons from 2014 to 2019. Methods: A retrospective review of the Center of Medicare and Medicaid Services' Open Payments Database was done to identify all industry payments to all general orthopaedic surgeons (ie, not subspecialty affiliated) from 2014 to 2019. The researchers analyzed total payments and subtype payments for yearly trends, and a regional analysis was done. The primary outcome was the overall trend in total median payments, which was assessed through the Jonckheere-Terpstra test. Descriptive statistics include medians with interquartile ranges. P < 0.05 was considered statistically significant. Results: Between 2014 and 2019, a total of 1,330,543 payments totaling $1.79 billion dollars was paid to 108,041 general orthopaedic surgeons. During this time, the number of surgeons receiving payments increased with a significant uptrend in median payments per surgeon (P < 0.001; Table 1). The top 25% percentile of general orthopaedic surgeons received >95% of payments, whereas the bottom 25% received P < 0.001) between 2014 and 2019, with the exception of “Ownership or Investment Interests” (P = 0.657) and “Royalty or License” (P = 0.517). Significant regional uptrends in median industry payments were also seen in the Midwest, Northeast, South, and West (P < 0.001). Four of the top five orthopaedic industry companies made payment increases between 2014 and 2019. Conclusion: Industry payments to general orthopaedic surgeons between 2014 and 2019 have increased with a considerable disparity in payments among the top-paid orthopaedic surgeons.

Social Media Use Among Foot and Ankle Orthopedic Surgeons
Digital media is an effective tool to enhance brand recognition and is currently referenced by more than 40% of orthopedic patients when selecting a physician. The purpose of this study was to evaluate the use of social media among foot and ankle (F&A) orthopedic surgeons, and the impact of that social media presence on scores of a physician-rated website (PRW). Randomly selected F&A orthopedic surgeons from all major geographical locations across the United States were identified using the AAOS.org website. Internet searches were then performed using the physician’s name and the respective social media platform. A comprehensive social media use index (SMI) was created for each surgeon using a scoring system based on social media platform use. The use of individual platforms and SMI was compared to the F&A surgeon’s Healthgrades scores. Descriptive statistics, unpaired Student t tests, and linear regression were used to assess the effect of social media on the PRW scores. A total of 123 board-certified F&A orthopedic surgeons were included in our study demonstrating varying social media use: Facebook (48.8%), Twitter (15.4%), YouTube (23.6%), LinkedIn (47.9%), personal website (24.4%), group website (52.9%), and Instagram (0%). The mean SMI was 2.4 ± 1.6 (range 0-7). Surgeons who used a Facebook page were older, whereas those using a group website were younger (P < .05). F&A orthopedic surgeons with a YouTube page had statistically higher Healthgrades scores compared to those without (P < .05). F&A orthopedic surgeons underused social media platforms in their clinical practice. Among all the platforms studied, a YouTube page was the most impactful social media platform on Healthgrades scores for F&A orthopedic surgeons. Given these findings, we recommend that physicians closely monitor their digital identity and maintain a diverse social media presence including a YouTube page to promote their clinical practice. Level IV.
