Orthopedic surgeons' transition into full-time practice over the last 20 years: an analysis using Ministry of Health billing data.

BACKGROUND: Underemployment is a reality for many new graduates, who accept locum or part-time work as an alternative to unemployment because of lack of opportunities. We sought to analyze orthopedic surgeons' Ontario Health Insurance Program (OHIP) billing data over a 20-year period as a proxy of practice patterns and hypothesized that billing in the first 6 years of practice would be affected by underemployment and locum. METHODS: We analyzed the annual average billing totals of orthopedic surgeons, broken down by year of graduation, year of billings, and number of surgeons billing in that year. We analyzed public census data of the Ontario population size as a proxy of orthopedic demand. RESULTS: A 2019 cross-sectional analysis showed that around 15 surgeons per graduating year were billing in Ontario from the 1995 to 2016 cohorts, while 2017 and 2018 saw an increase to 30 and 36 actively billing surgeons, respectively. The number returned to more historical numbers in 2019, with 20 actively billing surgeons. For those surgeons billing in Ontario, billing trends have been roughly stable, with average billings increasing each year for the first 6 years in practice (p < 0.001). Year of graduation did not have an effect on the first 6 years of billings (p > 0.5). Billings were stable after 6 years in practice (p > 0.09). CONCLUSION: The Ontario health care system has not expanded to support more orthopedic surgeons despite the aging and growing population; despite our growing population, the number of surgeons being trained and retained has not matched this growth. Further research needs to be done to guide optimal health human resource decision-making.

Patellar Fracture Surgery Performed Autonomously by Residents, Yields Similar Short-Term Outcomes to Surgery Performed by Fellowship-Trained Surgeons.

BACKGROUND: Open reduction and internal fixation are the gold-standard treatment for displaced patellar fractures. The current literature remains inconclusive on the relationship between resident participation in the operating room and optimal patient outcomes. We hypothesize that surgeries performed solely by residents, without attending supervision, can provide similar outcomes to those performed by fellowship-trained orthopedic surgeons, providing new insights into the relationship between resident autonomy and surgical outcomes in the field of orthopedic trauma. METHODS: A tertiary trauma center cohort was retrospectively reviewed for all surgically treated patellar fractures between 2015 and 2020. The cohort was divided into 2 groups: patients operated by residents and patients operated by orthopedic trauma specialists. Demographics, surgical parameters, and radiographs were compared between the groups to evaluate complications and reoperation rates, radiographic outcomes (such as hardware failure, or loss of reduction), and clinical outcomes (including residual pain, painful hardware, decreased range of motion, and infections). RESULTS: A total of 129 patellar fractures were included in the study. Demographics and ASA were similar between the groups. There were no significant differences in complications (p = 0.900) or reoperation rates (p = 0.817), with an average follow-up time of 8 months (SD ± 5.3). Residents had significantly longer surgery duration (p =0.002). However, the overall length of stay was shorter in the resident group (p < 0.001). CONCLUSION: The study shows patellar fracture surgery performed by adequately trained residents can provide similar outcomes to those performed by fellowship-trained orthopaedic trauma surgeons. These findings highlight the significance of surgical autonomy in residency and its role in contemporary surgical education.

Trends in Orthopaedic Surgery Workforce Diversity: Analyzing Changes Over Time.

INTRODUCTION: There are many reasons why orthopaedic surgeons move or change careers. We asked the questions: (1) What is the geographic distribution of orthopaedic surgeons with respect to age, sex, and race and ethnicity? (2) How has our workforce changed over time with regard to these factors? (3) Are there any patterns or trends detected regarding policy or regulatory events that coincide with these differences? METHODS: The American Academy of Orthopaedic Surgeons surveys over 30,000 members, collecting data on demographics, age, race sex, and practice statistics. We calculated geographic distributions and evaluated these differences over time-potential influences from malpractice suits or tort reform were investigated. RESULTS: Overall surgeon density increased over time. The largest negative changes were noted in District of Columbia, Wyoming, and North Dakota and positive changes in Colorado, South Dakota, and West Virginia. Age across all states increased (mean 1.7 years). Number of female surgeons increased in most states (4.6% to 5.7%). Number of African Americans increased from 1.6% to 1.8%, Hispanic/LatinX from 1.8% to 2.2%, Asian from 5.5% to 6.7%, and multiracial from 0.8% to 1.2%. No change was noted in the percentage of Native American surgeons. DISCUSSION: Surgeon density increased from 2012 to 2018; the cause for this change was not evident. Small increases in surgeon population, female surgeons, and in some underrepresented minorities were seen.

Factors influencing patient selection of orthopaedic surgeons for total hip (THA) and total knee arthroplasty (TKA).

INTRODUCTION: The importance of identifying how patients choose their healthcare providers has grown with the prevalence of consumer-centric health insurance plans. There is currently a lack of studies exploring the factors associated with how patients select their hip and knee joint arthroplasty surgeons. The purpose of this study was to determine how patients find their arthroplasty providers and the relative importance of various arthroplasty surgeon characteristics. METHODS: An electronic mail survey was sent to 3522 patients who had visited our institution for an arthroplasty surgeon office visit between August 2022 and January 2023. The survey consisted of multiple-choice questions, which aimed to inquire about the patients' referral sources for their current arthroplasty surgeon. In addition, patients were requested to rate the significance of 22 surgeon-related factors, on a scale of 1 (Not Important At All) to 5 (Very Important), in choosing their arthroplasty surgeon. RESULTS: Of the 3522 patients that received the survey, 538 patients responded (15.3%). The most common referral sources were physician referral (50.2%), family/friend referral (27.7%), and self-guided research (24.5%). Of those that were referred by a physician, 54.4% of respondents were referred by another orthopaedic provider. Patients rated board certification (4.72 ± 0.65), in-network insurance status (4.66 ± 0.71), fellowship training (4.50 ± 0.81), bedside manner/personality (4.32 ± 0.86), and facility appearance (4.26 ± 0.81) as the five most important factors in picking an arthroplasty surgeon. Television (1.42 ± 0.83), print (1.50 ± 0.88), and online (1.58 ± 0.93) advertisements, along with social media presence (1.83 ± 1.08), and practice group size (2.97 ± 1.13) were rated as the five least important factors. CONCLUSION: Patients are most likely to select an arthroplasty surgeon based on referral from other physicians, namely orthopedic surgeons, in addition to board certification status, in-network insurance, and fellowship training. Overall, these findings highlight the importance of physician credentials and reputation within the orthopaedic community in order to attract and retain patients.

Pregnancy and infertility in orthopedics: A review of the current state.

BACKGROUND: Orthopedic surgery continues to have one of the lowest rates of female trainees among all medical specialties in the United States. Barriers to pursuing a surgical residency include the challenges of family planning and work-life balance during training. METHODS: A systematic literature search of articles published between June 2012 and December 2022 in the MEDLINE, EMBASE, and Cochrane databases was performed in January 2023 according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). Studies were included if they evaluated pregnancy and peripartum experience and/or outcomes amongst orthopedic surgeons or trainees. RESULTS: Eighteen studies were included. Up to 67.3% of female orthopedic surgeons and trainees and 38.7% of their male counterparts delayed childbearing during residency. The most reported reasons for this delay included career choice as an orthopedic surgeon, residency training, and reputational concerns among faculty or co-residents. Infertility ranged from 17.0% to 30.4% in female orthopedic surgeons and up to 31.2% suffered obstetric complications. Assisted Reproductive Technology (ART) resulted in 12.4%-56.3% of successful pregnancies. Maternity and paternity leaves ranged from 1 to 11 weeks for trainees with more negative attitudes associated with maternal leave. CONCLUSIONS: Female orthopedic trainees and attending delay childbearing, experience higher rates of obstetric complications, and more stigma associated with pregnancy compared to their male colleagues. Program and institutional policies regarding maternity and paternity leave are variable across programs, and therefore, attention should be directed toward standardizing policies.

Do all patients with history of pelvic ring injuries need a cesarean section? - A survey of orthopaedic and obstetric providers.

OBJECTIVE(S): The recommended mode of delivery following pelvic ring fractures with surgical fixation is unclear. The objective of this study was to assess expert opinions from orthopaedic surgeons and obstetrician gynecologists on their recommended delivery recommendations for pregnant individuals with a history of pelvic ring injury, and to see if there was any difference in recommendations between the two specialties, and what factors influenced recommendations. STUDY DESIGN: An electronic, web-based survey was administered to a convenience sample of orthopaedic surgeons and obstetrician gynecologists, via advertisement to members of the Orthopaedic Trauma Association (OTA), the Society for Maternal Fetal Medicine, and querying obstetrician gynecologists practicing within the Military Health System. The survey was administered from November 2021 to December 2022. A two-proportion z-test, Chi-square or Fisher's Exact Test, and descriptive statistics were used to analyze data. RESULTS: Survey respondents included 44 orthopaedic surgeons and 37 obstetricians. A total of 74 % obstetricians would recommend a trial of labor with hardware in place, while orthopaedic surgeon's recommendations varied based on the type of fixation. Forty four, 100 % of orthopaedic surgeons, recommended trial of labor if non-operative pelvic injury or unilateral posterior fixation only, 88 % recommended trial of labor if bilateral posterior fixation only, and 47.7 % for anterior trans-symphyseal plating only, 50 % for unilateral posterior and trans-symphyseal plating, and 43.2 % for bilateral posterior fixation with trans-symphyseal plating. CONCLUSIONS: The results of these surveys demonstrate the lack of consensus as to the most appropriate birth plan for patients with a history of pelvic ring injuries. Vaginal delivery following pelvic ring fracture and fixation is possible, yet these patients are significantly more likely to undergo cesarean section than the general population. As such, we recommend that women who become pregnant after operative treatment of a pelvic ring injury develop an in-depth birthing plan with their obstetrician to determine the best course.

National Trends in Orthopaedic Pain Management from 2016 to 2020.

INTRODUCTION: Effective pain management is vital in orthopaedic care, impacting postoperative recovery and patient well-being. This study aimed to discern national and regional pain prescription trends among orthopaedic surgeons through Medicare claims data, using geospatial analysis to ascertain opioid and nonopioid usage patterns across the United States. METHODS: Physician-level Medicare prescription databases from 2016 to 2020 were filtered to orthopaedic surgeons, and medications were categorized into opioids, muscle relaxants, anticonvulsants, and NSAIDs. Patient demographics were extracted from a Medicare provider demographic data set, while county-level socioeconomic metrics were obtained primarily from the American Community Survey. Geospatial analysis was conducted using Geoda software, using Moran I statistic for cluster analysis of pain medication metrics. Statistical trends were analyzed using linear regression, Mann-Whitney U test, and multivariate logistic regression, focusing on prescribing rates and hotspot/coldspot identification. RESULTS: Analysis encompassed 16,505 orthopaedic surgeons, documenting more than 396 million days of pain medication prescriptions: 57.42% NSAIDs, 28.57% opioids, 9.84% anticonvulsants, and 4.17% muscle relaxants. Annually, opioid prescriptions declined by 4.43% ( P < 0.01), while NSAIDs rose by 3.29% ( P < 0.01). Opioid prescriptions dropped by 210.73 days yearly per surgeon ( P < 0.005), whereas NSAIDs increased by 148.86 days ( P < 0.005). Opioid prescriptions were most prevalent in the West Coast and Northern Midwest regions, and NSAID prescriptions were most prevalent in the Northeast and South regions. Regression pinpointed spine as the highest and hand as the lowest predictor for pain prescriptions. DISCUSSION: On average, orthopaedic surgeons markedly decreased both the percentage of patients receiving opioids and the duration of prescription. Simultaneously, the fraction of patients receiving NSAIDs dramatically increased, without change in the average duration of prescription. Opioid hotspots were located in the West Coast, Utah, Colorado, Arizona, Idaho, the Northern Midwest, Vermont, New Hampshire, and Maine. Future directions could include similar examinations using non-Medicare databases.

Women in leadership in orthopaedic sports medicine societies throughout the world.

OBJECTIVES: The proportion of women in orthopaedic surgery is low compared to other specialties, despite equal numbers of male and female students entering the medical profession. This gender disparity persists across various aspects of orthopaedic sports medicine, such as academic leadership, medical education, and on the sidelines. The purpose of this study was to conduct a comprehensive and updated global analysis of female representation in leadership positions within orthopaedic sports medicine and arthroscopy societies throughout the world. METHODS: Publicly available websites for orthopaedic sports medicine societies throughout the world were evaluated. For societies that met inclusion criteria, the following data were collected: types of leadership positions available and breakdown of male and female orthopaedic surgeons in those positions. RESULTS: There were a total of 55 societies analyzed from North America (5, 9.1%), South America (8, 14.5%), Europe (18, 32.7%), Asia (13, 23.6%), Africa (2, 3.6%), the Middle East (3, 5.5%) and Australia (3, 5.5%), as well as 3 international societies (5.5%). North America had the highest percentage of women in leadership positions with 19 of 97 positions (19.6%), followed by international societies with 11 of 92 (12.0%) positions filled by women. The Middle East and Australia had the fewest number of women, with all-male leadership. Globally, female orthopaedic surgeons served in 11 of 181 (6.1%) board of directors positions, 16 of 192 (8.3%) executive committees positions, 17 of 143 (11.9%) committee chair positions, 2 of 18 (11.1%) officer positions, 1 of 12 (8.3%) council positions, and 2 of 7 (28.6%) spokesperson positions. CONCLUSION: While some countries have higher representation than others, the number of women in leadership positions in orthopaedic sports medicine societies throughout the world is significantly less than their male counterparts. While this is a preliminary analysis, future studies should aim to evaluate these trends over time. Providing equitable opportunities for women to rise into high-ranking positions in orthopaedic sports medicine may contribute to the interest of women and other minorities in the field of sports medicine and help improve diversity.

Gender differences among shoulder arthroplasty surgeons: past, present, and future.

BACKGROUND: Reducing differences in the gender representation of shoulder arthroplasty surgeons may help optimize patient care. This work aimed to determine (1) the current gender distribution of surgeons performing shoulder arthroplasty, (2) how gender relates to practice patterns among shoulder arthroplasty surgeons, and (3) how gender distribution has been changing over time. METHODS: The Medicare Provider Utilization and Payment Data for the years 2012-2020 were used to identify orthopedic surgeons performing anatomic and reverse total shoulder arthroplasty (Current Procedural Terminology code 23472). The data set provides self-reported gender, credentials, National Provider Identifier, annual volume of all procedures (based on Current Procedural Terminology codes) that were performed ≥11 times in the calendar year, and location for all included providers. The data set was linked to the Medicare Physician Compare data set using National Provider Identifiers to determine hospital affiliations, year of medical school graduation, and graduating medical school. All included hospitals were queried to determine academic status (affiliated orthopedic residency or fellowship program). The American Shoulder and Elbow Surgeons (ASES) directory was reviewed to determine the gender breakdown of current members. RESULTS: The number of surgeons performing ≥11 shoulder arthroplasties annually increased from 821 (13 women [1.6%]) in 2012 to 1840 (53 women [2.9%], P = .05) in 2019. One female surgeon ranked in the top 100 surgeons by shoulder arthroplasty volume in 2012 and in 2020. Female surgeons graduated more recently from medical school (mean, 2005) compared with male surgeons (mean, 1997; P < .001). About 10% of female surgeons (10.8%, 12 of 111) and male surgeons (9.1%, 229 of 2528) practiced at hospitals with orthopedic residents (P = .50). Female surgeons performing shoulder arthroplasty were less likely than male surgeons to perform total knee arthroplasty (29.4% vs. 54.1%, P < .001) and total hip arthroplasty (12.6% vs. 34.7%, P < .001). There were 86 female members of ASES (6.7%, 86 of 1275), with a significant difference in the proportion of women in differing membership categories (P = .017). DISCUSSION AND CONCLUSION: A diverse cohort of high-volume shoulder replacement surgeons is integral to delivering high-quality shoulder arthroplasty. Currently, the proportion of women performing high-volume shoulder replacement in the United States is small, with little improvement in recent years. However, women performing shoulder arthroplasty are younger and are often involved in academic practices, and the membership of ASES is increasingly female. Continued efforts to promote orthopedics-and to mentor female residents and medical students interested in shoulder surgery-may bring real change to the gender differences among shoulder replacement surgeons over the coming years.

Understanding Financial Relationships Between Orthopedic Surgeons and Industry for Research.

OBJECTIVE: This study sought to understand trends in industry payments for research awarded to orthopedic surgeons. MATERIALS AND METHODS: The Centers for Medicare & Medicaid Services Open Payments database was queried for the years 2016 to 2021 for industry payments for research. Financial analyses were performed to understand temporal trends and differences by orthopedic subspecialty and principal investigator characteristics such as sex. The threshold for statistical significance was set at .05. RESULTS: A total of 2014 orthopedic surgeons were identified, among whom 542 adult reconstruction (27%) and 460 sports medicine (23%) surgeons were major beneficiaries. Seventy-one female orthopedic surgeons comprised the minority (4%). Total research payments awarded during the study period aggregated to $266,633,592, with adult reconstruction ($88,819,047; 33%) and sports medicine ($57,949,822; 22%) receiving the highest amounts. Total research payments awarded trended upward yearly except for a decline in 2020 that subsequently rebounded (P<.001). Median annual research payment per orthopedic surgeon was $13,375. Median total industry payments per orthopedic surgeon differed between specialties (P <.001), with the highest amounts for adult reconstruction ($44,063) and sports medicine ($34,567) and the lowest amounts for hand ($12,052) and foot and ankle ($19,233). Median total payments did not differ significantly when stratified by sex (P=.276) and region (P=.906). Specialties in which the respective top three companies offered the majority of the research funding were musculoskeletal oncology (90%), pediatric orthopedics (66%), and shoulder and elbow (64%). CONCLUSION: These results can be used as a primer for orthopedic surgeons seeking to leverage industry relationships to fund translational research. [Orthopedics. 2024;47(3):172-178.].

The Association Between Orthopaedic Surgeon Academic Productivity Metrics and Compensation from Medical Industry.

INTRODUCTION: Academic research has value well beyond personal financial gain. However, these endeavors do require a notable amount of time and opportunity cost. Academic productivity may raise a researcher's profile within the field, increasing the likelihood for interactions with the medical industry and possibly cultivating relationships with future monetary significance. METHODS: Queries of the Centers for Medicaid and Medicare Services publicly available Open Payments System allowed for extraction of industry compensation data for orthopaedic surgeons. Aggregate data produce three compensation groups (mean annual income) for individual physicians: none; 1 to $100,000; and >$100,000. Physicians in the highest income category were matched 1:1 with physicians in each of the other two compensation groups. Selected physicians then underwent an academic productivity assessment. Queries of Web of Science, Scopus, and Google Scholar User Profile databases provided the h-index and m-index for each surgeon. Bivariate and multivariate analyses produced statistical results. In addition to the analysis of the tiered income groups, analysis of compensation as a continuous variable also occurred. RESULTS: From 2016 to 2020, 636, 7,617, and 22,091 US orthopaedic surgeons earned mean annual industry compensation >$100,000; between $1 and $100,000; and $0, respectively. Royalties (80.8%) predominated in the top earning group, compared with Consulting Fees (46.5%) in the second-tier group. The highest income group had higher h-index ($0 versus $1 to 100,000 versus >$100,000 = 3.6 versus 7.5 versus 20.0, P < 0.001) and m-index ($0 versus $1 to 100,000 versus >$100,000 = 0.26 versus 0.44 versus 0.80, P < 0.001) scores than either the intermediate or no compensation groups. In addition, h-index and m-index correlated positively with total compensation (h-index: r = 0.32, P < 0.001; m-index: r = 0.20, P < 0.001). Multivariable analysis of factors associated with increased industry compensation identified h-index (B = 0.034, P < 0.001) and years active (B = 0.042, P < 0.001) as having significant associations with physician compensation. Physician subspecialty also correlated with industry compensation. DISCUSSION: Academic research can provide invaluable contributions to the improvement of patient care. These efforts often require notable personal sacrifice with minimal direct remuneration. However, academic productivity metrics correlate positively with industry compensation, highlighting a possible supplementary benefit to scholarly efforts. LEVEL OF EVIDENCE: Level III.

Prevalence of gender-based and sexual harassment within orthopedic surgery in Canada.

BACKGROUND: Gender-based and sexual harassment are prevalent in the medical profession. We aimed to quantify the prevalence of such behaviours within orthopedic surgery in Canada and to identify any risk factors for experiencing gender-based or sexual harassment in the workplace. METHODS: In collaboration with the Canadian Orthopaedic Association, we conducted a Canada-wide email questionnaire survey in June 2019 of all orthopedic surgeons registered with the Canadian Orthopaedic Association and the Canadian Orthopaedic Residents' Association. The development of our questionnaire was informed by a review of the literature and published surveys on gender-based and sexual harassment, and consultation with researchers in intimate partner violence. We conducted a multivariable logistic regression analysis to identify risk factors for harassment. RESULTS: Of the 1783 surgeons invited to participate, 465 returned the questionnaire (response rate 26.1%); the response rate was 48.1% for females and 22.1% for males. Overall, 331/433 respondents (76.4%, 95% confidence interval [CI] 72%-80%) and 315/423 respondents (74.5%, 95% CI 70%-78%) reported having experienced at least 1 occurrence of gender-based and sexual harassment, respectively. Women were significantly more likely than men to have experienced both gender-based and sexual harassment (odds ratio [OR] 16.2, 95% CI 4.8-54.0, and OR 2.2, 95% CI 1.2-4.0, respectively). Respondents who identified as nonwhite were significantly less likely than those who identified as white to have experienced gender-based harassment (OR 0.5, 95% CI 0.3-0.99). CONCLUSION: The prevalence of gender-based and sexual harassment is high within Canadian orthopedic surgery, and women are at highest risk for experiencing harassment. The results may provide the impetus for orthopedic societies to develop action plans and to re-examine and enforce policies to address these damaging behaviours appropriately.

What Can We Learn From Surgeons Who Perform THA and TKA and Have the Lowest Revision Rates? A Study from the Australian Orthopaedic Association National Joint Replacement Registry.

BACKGROUND: Long-term implant survivorship in THA and TKA involves a combination of factors related to the patient, the implants used, and the decision-making and technical performance of the surgeon. It is unclear which of these factors is the most important in reducing the proportion of revision surgery. QUESTIONS/PURPOSES: We used data from a large national registry to ask: In patients receiving primary THA and TKA for a diagnosis of osteoarthritis, do (1) the reasons for revision and (2) patient factors, the implants used, and the surgeon or surgical factors differ between surgeons performing THA and TKA who have a lower revision rate compared with all other surgeons? METHODS: Data were analyzed for all THA and TKA procedures performed for a diagnosis of osteoarthritis from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) from September 1, 1999, when collection began, to December 31, 2018. The AOANJRR obtains data on more than 98% of joint arthroplasties performed in Australia. The 5-year cumulative percent revision (CPR) was identified for all THAs and TKAs performed for a diagnosis of osteoarthritis with 95% confidence intervals (overall CPR); the 5-year CPR with 95% CIs for each surgeon was calculated for THA and TKA separately. For surgeons to be included in the analysis, they had to have performed at least 50 procedures and have a 5-year CPR. The 5-year CPR with 95% CIs for each THA and TKA surgeon was compared with the overall CPR. Two groups were defined: low revision rate surgeons (the upper confidence level for a given surgeon at 5 years is less than 3.84% for THA and 4.32% for TKA), and all other surgeons (any surgeon whose CPR was higher than those thresholds). The thresholds were determined by setting a cutoff at 20% above the upper confidence level for that class. The approach we used to define a low revision rate surgeon was similar to that used by the AOANJRR for determining the better-performing prostheses and is recommended by the International Prosthesis Benchmarking Working Group. By defining the groups in this way, a significant difference between these two groups is created. Determining a reason for this difference is the purpose of presenting the proportions of different factors within each group. The study group for THA included 116 low revision rate surgeons, who performed 88,392 procedures (1619 revised, 10-year CPR 2.7% [95% CI 2.6% to 2.9%]) and 433 other surgeons, who performed 170,094 procedures (6911 revised, 10-year CPR 5.9% [95% CI 5.7% to 6.0%]). The study group for TKA consisted of 144 low revision rate surgeons, who performed 159,961 procedures (2722 revised, 10-year CPR 2.6% [95% CI 2.5% to 2.8%]) and 534 other surgeons, who performed 287,232 procedures (12,617 revised, 10-year CPR 6.4% [95% CI 6.3% to 6.6%]). These groups were defined a priori by their rate of revision, and the purpose of this study was to explore potential reasons for this observed difference. RESULTS: For THA, the difference in overall revision rate between low revision rate surgeons and other surgeons was driven mainly by fewer revisions for dislocation, followed by component loosening and fracture in patients treated by low revision rate surgeons. For TKA, the difference in overall revision rate between low revision rate surgeons and other surgeons was driven mainly by fewer revisions for aseptic loosening, followed by instability and patellofemoral complications in patients treated by low revision rate surgeons. Patient-related factors were generally similar between low revision rate surgeons and other surgeons for both THA and TKA. Regarding THA, there were differences in implant factors, with low revision rate surgeons using fewer types of implants that have been identified as having a higher-than-anticipated rate of revision within the AOANJRR. Low revision rate surgeons used a higher proportion of hybrid fixation, although cementless fixation remained the most common choice. For surgeon factors, low revision rate surgeons were more likely to perform more than 100 THA procedures per year, while other surgeons were more likely to perform fewer than 50 THA procedures per year. In general, the groups of surgeons (low revision rate surgeons and other surgeons) differed less in terms of years of surgical experience than they did in terms of the number of cases they performed each year, although low revision rate surgeons, on average, had more years of experience and performed more cases per year. Regarding TKA, there were more differences in implant factors than with THA, with low revision rate surgeons more frequently performing patellar resurfacing, using an AOANJRR-identified best-performing prosthesis combination (with the lowest rates of revision), using fewer implants that have been identified as having a higher-than-anticipated rate of revision within the AOANJRR, using highly crosslinked polyethylene, and using a higher proportion of cemented fixation compared with other surgeons. For surgeon factors, low revision rate surgeons were more likely to perform more than 100 TKA procedures per year, whereas all other surgeons were more likely to perform fewer than 50 procedures per year. Again, generally, the groups of surgeons (low revision rate surgeons and other surgeons) differed less in terms of years of surgical experience than they did in terms of the number of cases they performed annually, although low revision rate surgeons, on average, had more years of experience and performed more cases per year. CONCLUSION: THAs and TKAs performed by surgeons with the lowest revision rates in Australia show reductions in all of the leading causes of revision for both THA and TKA, in particular, causes of revision related to the technical performance of these procedures. Patient factors were similar between low revision rate surgeons and all other surgeons for both THA and TKA. Low revision rate THA surgeons were more likely to use cement fixation selectively. Low revision rate TKA surgeons were more likely to use patella resurfacing, crosslinked polyethylene, and cemented fixation. Low revision rate THA and TKA surgeons were more likely to use an AOANJRR-identified best-performing prosthesis combination and to use fewer implants identified by the AOANJRR as having a higher-than-anticipated revision rate. To reduce the rate of revision THA and TKA, surgeons should consider addressing modifiable factors related to implant selection. Future research should identify surgeon factors beyond annual case volume that are important to improving implant survivorship. LEVEL OF EVIDENCE: Level III, therapeutic study.

Does the publication of NICE guidelines for venous thromboembolism chemical prophylaxis influence the prescribing patterns of UK hip and knee surgeons?

INTRODUCTION: We assessed the practice of surgeons regarding venous thromboembolism (VTE) chemical prophylaxis for total hip replacement (THR) and total knee replacement (TKR), before and after issuing of updated National Institute for Health and Care Excellence (NICE) guidance in 2018. METHODS: A survey, circulated through the British Hip Society and regional trainee networks/collaboratives, was completed by 306 UK surgeons at 187 units. VTE chemical prophylaxis prescribing patterns for surgeons carrying out primary THR (n=258) and TKR (n=253) in low-risk patients was assessed after publication of 2018 NICE recommendations. Prescribing patterns before and after the NICE publication were subsequently explored. RESULTS: Following the new guidance, 34% (n=87) used low-molecular-weight heparin (LMWH) alone, 33% (n=85) aspirin (commonly preceded by LMWH) and 31% (n=81) direct oral anticoagulants (DOACs: with/without preceding LMWH) for THR. For TKR, 42% (n=105) used aspirin (usually monotherapy), 31% (n=78) LMWH alone and 27% (n=68) DOAC (with/without preceding LMWH). NICE guidance changed the practice of 34% of hip surgeons and 41% of knee surgeons, with significantly increased use of aspirin preceded by LMWH for THR (before=25% vs after=73%; p<0.001), and aspirin for TKR (before=18% vs after=84%; p<0.001). Significantly more regimens were NICE guidance compliant after the 2018 update for THR (before=85.7% vs after=92.6%; p=0.011) and TKR (before=87.0% vs after=98.8%; p<0.001). CONCLUSION: Over one-third of surveyed surgeons changed their VTE chemical prophylaxis in response to 2018 NICE recommendations, with more THR and TKR surgeons now compliant with latest NICE guidance. The major change in practice was an increased use of aspirin for VTE chemical prophylaxis.

Management of patients with hip fracture receiving anticoagulation: What are we doing in Canada?

BACKGROUND: Direct oral anticoagulants (DOACs) are rapidly replacing warfarin for therapeutic anticoagulation; however, many DOACs are irreversible and may complicate bleeding in emergent situations such as hip fracture. In this setting, there is a lack of clear guidelines for the timing of surgery. The purpose of this study was to evaluate the current practices of Canadian orthopedic surgeons who manage patients with hip fracture receiving anticoagulation. METHODS: In January-March 2018, we administered a purpose-specific cross-sectional survey to all currently practising orthopedic surgeons in Canada who had performed hip fracture surgery in 2017. The survey evaluated approaches to decision-making and timing of surgery in patients with hip fracture receiving anticoagulation. RESULTS: A total of 280 surgeons representing a mix of academic and community practice, seniority and fellowship training responded. Nearly one-quarter of respondents (66 [23.4%]) were members of the Canadian Orthopaedic Trauma Society (COTS). Almost three-quarters (206 [73.6%]) felt that adequate clinical guidelines for patients with hip fracture receiving anticoagulation did not exist, and 177 (61.9%) indicated that anesthesiology or internal medicine had a greater influence on the timing of surgery than the attending surgeon. A total of 117/273 respondents (42.9%) indicated that patients taking warfarin should have immediate surgery (with or without reversal), compared to 63/270 (23.3%) for patients taking a DOAC (p < 0.001). Members of COTS were more likely than nonmembers to advocate for immediate surgery in all patients (p < 0.05). CONCLUSION: There is wide variability in Canada in the management of patients with hip fracture receiving anticoagulation. Improved multidisciplinary communication, prospectively evaluated treatment guidelines and focus on knowledge translation may add clarity to this issue. LEVEL OF EVIDENCE: IV.

Orthopaedic Trauma Research Priorities in Latin America: Developing Consensus Through a Modified Delphi Approach.

BACKGROUND: Despite a substantial burden of musculoskeletal injury, orthopaedic trauma studies in Latin America are lacking. The purpose of the present study was to identify research priorities among orthopaedic trauma surgeons in Latin America. METHODS: Research questions were solicited from members of the Asociación de Cirujanos Traumatólogos de las Américas. Participants rated questions by importance from 1 to 9. All questions were redistributed with an aggregate rating, and participants rerated questions with knowledge of group responses. RESULTS: Seventy-eight participants completed the first survey and were included in subsequent surveys. The mean age was 51.8 years, and most participants were male (92%), had completed an orthopaedic trauma fellowship (60.3%), and participated in research (80.8%). Seventeen countries were represented; 5 respondents were from a high-income country, 67 were from an upper middle-income country, and 6 were from a lower middle-income country. Sixty-five questions were identified. Six questions were rated from 1 to 3 ("more important") by >70% of participants: (1) What is the optimal treatment protocol for elderly patients with hip fracture? (2) What is the most effective initial and definitive management of musculoskeletal injury, including timing and surgical strategy, for the polytraumatized patient? (3) What is the ideal state of open fracture treatment, including timeliness and method of antibiotics, debridement, surgical fixation, and closure or coverage, at each hospital level in the health-care system? (4) What patient and fracture characteristics predict infection after musculoskeletal injury? (5) What is the current state of treatment for fracture-related infection, including timeliness and method of antibiotics and surgical intervention, at each hospital level in the health-care system? (6) What is the optimal protocol for temporary management for the hemodynamically unstable patient with a pelvic or acetabular fracture? CONCLUSIONS: This modified Delphi study of orthopaedic trauma surgeons in Latin America identified geriatric hip fractures, polytrauma, open fractures, musculoskeletal infection, and pelvic and acetabular fractures as top research priorities. This information is important for resource allocation and goal setting for orthopaedic trauma in the region.

Estimated exposure of spine surgeons to radiation / Estimativa da exposição de cirurgiões de coluna vertebral à radiação / Estimativa de la exposición de cirujanos de columna vertebral a la radiación

ABSTRACT Objective To estimate the amount of radiation received and accumulated in the bodies of two surgeons, one being the responsible surgeon and the other the assistant, performing spine surgery procedures over a period of 25 years. Methods Seventy-two spinal surgeries were performed during a seven-month period and the radiation loads were measured in both surgeons. The measurement of radiation was captured in fluoroscopy in anteroposterior and lateral incidences. The surgeon and the assistant used two dosimeters, one in the cervical region protecting the thyroid and the other on the lead apron in the genital region. The radioactive loads were measured in millisieverts and the accumulated charges were recorded monthly in both regions of the body in the two surgeons for seven months and the means for the work periods (1, 5, 10, 15, 20 and 25 years) were estimated. Results It was observed that in the surgeon the average accumulated radiation loads were 131.9% and 176.92% higher than those of the assistant in the cervical and genital regions, respectively. Conclusion While the use of X-rays is indispensable in routine orthopedic surgery, we have to consider the development of techniques of protection, rigor and discipline in the use of safety materials for surgeons. Preventive exposure reduction measures such as using thyroid protection equipment and turning the head away from the patient during fluoroscopy, among others, should be mandatory to promote less radiation exposure.

RESUMO Objetivo Estimar a quantidade de radiação recebida e acumulada no corpo de dois cirurgiões, durante período de 25 anos de trabalho, sendo um o cirurgião responsável e outro, assistente, nos procedimentos de cirurgia da coluna vertebral. Métodos Foram realizadas 72 cirurgias de coluna vertebral em um período de sete meses, e as cargas de radiação foram medidas nos dois cirurgiões. A medição da radiação foi captada em fluoroscópio nas incidências anteroposterior e de perfil. O cirurgião e o auxiliar utilizaram dois dosímetros, sendo um na região cervical protegendo a tireoide e outro sobre o avental de chumbo, na região genital. As cargas radioativas foram medidas em milisievert e as cargas acumuladas foram registradas mensalmente em ambas as regiões do corpo nos dois cirurgiões, durante sete meses, foram estimadas as médias no período (1, 5, 10, 15, 20 e 25 anos) de trabalho. Resultados Observou-se que no cirurgião as médias das cargas de radiação acumulada foram 131,9% e 176,92% superiores às do assistente nas regiões cervical e genital, respectivamente. Conclusão Enquanto o uso dos raios X for indispensável na rotina da cirurgia ortopédica, há de se considerar o desenvolvimento de técnicas de proteção, rigor e disciplina no uso materiais de segurança para os cirurgiões. Medidas preventivas de redução da exposição, como uso de equipamento para proteção da tireoide e girar a cabeça para se afastar do paciente durante a fluoroscopia, entre outras, devem ser obrigatórias para promover menor exposição à radiação. Nível de evidência II; Estudo prospectivo comparativo.

Radiation in orthopaedics (RIO) study: a national survey of UK orthopaedic surgeons.

OBJECTIVES: Orthopaedic surgeons have a responsibility to minimise risks of ionising radiation to patients, themselves and staff. This study aims to establish the understanding of radiation practice, legislation and risk by orthopaedic surgeons. METHODS: A nationwide online survey of UK-based orthopaedic surgeons was conducted. Participants answered 18 multiple-choice questions assessing level of radiation safety training, basic principles/knowledge of ionising radiation, relevant legislation and operating practice. RESULTS: A total of 406 surgeons completed the survey. 92% reported using intraoperative ionising radiation at least once per week. 38% received no formal training on radiation safety. Knowledge of basic principles of radiation and legislation was limited. There was variable knowledge when labelling an image intensifier machine and choosing its safest orientation. Poor uptake of radiation protection equipment was noted. Only 19% agreed they had adequate training in ionising radiation safety and 27% reported receiving adequate training in equipment emitting ionising radiation in the operating theatre. CONCLUSION: Many orthopaedic surgeons in the UK do not believe they are adequately trained in radiation safety. There is a deficiency amongst practicing surgeons in basic knowledge, relevant legislation and practicalities of the use of ionising radiation in the operating room. This could potentially put patients and health-care professionals at additional risk. We recommend that a standardised national training programme on the basic principles and safety of ionising radiation is implemented for all practicing orthopaedic surgeons. ADVANCES IN KNOWLEDGE: This paper is the first UK national survey amongst orthopaedic surgeons and is one of the largest reported internationally.

The impact of Covid-19 pandemic related lockdown on clubfoot practice: Type of study design: Retrospective cross-sectional study.

ABSTRACT: We investigated whether the number of pediatric patients with congenital clubfoot treated with the Ponseti method decreased during the Covid-19 pandemic or not in a rural area. So we aimed to guide orthopedic surgeons and health infrastructure for future pandemics to be prepared in hospitals of rural areas for the treatment of children with congenital clubfoot.One hundred and fifty-four patients with clubfoot who were admitted to our clinic were evaluated retrospectively from March 2017 to December 2020. Institutional hospital electronic database was used to detect the number of weeks between the birth and first cast performed in clinic and the number of casts been applied and unilaterality or bilaterality. Patients were divided into four groups, which included pandemic period and three previous years. Recorded data were analyzed statistically to detect if there is a difference between the numbers of the patients in pandemic period and three previous years.The number of patients with clubfoot admitted to our hospital between March 2020 and December 2020 increased by 140% compared to previous year. There was a statistically significant difference between the average number of cast applications of Group 4 and other groups (P <.001). Achilles tenotomy was performed in 44 (61.1%) of 72 patients admitted during the pandemic period. Only 4 (13.3%) out of 30 patients admitted between March 2019 and December 2019 were performed Achilles tenotomy.We detected an increase in the number of clubfoot cases admitted to our rural-based hospital during the Covid-19 pandemic, treated with casting or surgically. We think this is because of preventive measures during the pandemic, which caused parents could not reach urban for treatment.
