Financial Impact of Magnetic Resonance Imaging in the Surgical Treatment of Foot and Ankle Osteomyelitis.

Magnetic resonance imaging (MRI) is generally considered the most sensitive imaging for diagnosis of osteomyelitis; however, it is associated with significant cost and is at times ordered as initial screening imaging when a less resource-intensive test would suffice. The purpose of this retrospective cohort study was to examine the differences between patients with osteomyelitis of the foot and ankle, and their subsequent treatment course, who underwent MRI compared with those who did not. Financial impact of MRI as it relates to clinical decision-making was also calculated. Patients treated for a diagnosis of osteomyelitis of the foot and ankle from 2009 to 2015 were retrospectively identified. Demographics, imaging modalities, and operative procedures for each patient were collected. An "impact MRI" was defined as one that led to a subsequent operative procedure within the same admission. The impact cost of an MRI was estimated using the equation: (average MRI cost) × (total MRIs/impact MRIs). A total of 144 patients underwent 220 MRIs, and 399 patients did not have MRIs. The operative rate between the 2 groups was similar (70.8% versus 70.4%, p = .93). Multiple linear regression showed that MRI was not a significant predictor of operation (p = .50). However, we found a significant correlation between MRI use and operative intervention for patients with increased comorbidities. From 2011 to 2015, there was a significant increase in impact cost, while controlling for average MRI cost ($8172 to $15,292, p ≤ .05). Over the study period, the impact cost of an MRI significantly increased from 1.8 to 5.0 times the average cost.

Obesity is Not Associated with Increased Short-term Complications After Primary Total Shoulder Arthroplasty.

BACKGROUND: Few studies have analyzed the association between elevated BMI and complications after total shoulder arthroplasty (TSA). Previous studies have not consistently arrived at the same conclusion regarding whether obesity is associated with a greater number of postoperative complications. We used a national surgical database to compare the 30-day complication profile and hospitalization outcomes after primary TSA among patients in different BMI categories. QUESTIONS/PURPOSES: We asked: (1) Is obesity associated with an increased risk of complications within 30 days of primary TSA? (2) Is obesity associated with increased operative time? METHODS: The American College of Surgeons National Surgical Quality Improvement Program(®) database for 2006 to 2012 was queried to identify all patients who underwent a primary TSA for osteoarthritis of the shoulder. The ACS-NSQIP(®) database was selected for this study as it is a nationally representative database that provides prospectively collected perioperative data and a comprehensive patient medical profile. Exclusion criteria included revision TSA, infection, tumor, or fracture. We analyzed 4796 patients who underwent a primary TSA for osteoarthritis of the shoulder. Patients who underwent a TSA were divided in four BMI categories: normal (18.5-25 kg/m(2)), overweight (25-30 kg/m(2)), obesity Class 1 (30-35 kg/m(2)), and obesity Class 2 or greater (> 35 kg/m(2)). Perioperative hospitalization data and 30-day postoperative complications were compared among different BMI classes. Differences in patient demographics, preoperative laboratory values, and preexisting patient comorbidities also were analyzed among different BMI groups, and multivariate analysis was used to adjust for any potential confounding variables. RESULTS: There was no association between BMI and 30-day complications after surgery (normal as reference, overweight group relative risk: 0.57 [95% CI, 0.30-1.06], p = 0.076; obesity Class 1 relative risk: 0.52 [95% CI, 0.26-1.03], p = 0.061; obesity Class 2 or greater relative risk: 0.54 [95% CI, 0.25-1.17], p = 0.117). However, greater BMI was associated with longer surgical times (for normal BMI control group: 110 minutes, SD, 42 minutes; overweight group: 115 minutes, SD, 46 minutes, mean difference to control: 5 minutes [95% CI, -1 to 10 minutes], p = 0.096; obesity Class 1: 120 minutes, SD, 43 minutes, mean difference: 10 minutes [95% CI, 5-15 minutes], p < 0.001; obesity Class 2 or greater: 122 minutes, SD, 45 minutes, mean difference: 12 minutes [95% CI, 6-18 minutes], p < 0.001). CONCLUSIONS: Although the surgical time increased for patients with greater BMI, the 30-day complications and perioperative hospitalization data after TSA were not different in patients with increased BMI levels. Obesity alone should not be a contraindication for TSA, and obese patients can expect similar incidences of postoperative complications. The preoperative medical optimization plan should be consistent with that of patients who are not obese who undergo TSA. LEVEL OF EVIDENCE: Level III, therapeutic study.

Gender Disparities in Osteoarthritis-Related Health Care Utilization Before Total Knee Arthroplasty.

OBJECTIVES: Women older than 50 years have higher prevalence of knee osteoarthritis (OA) and experience greater functional disability than men. No studies have examined large populations to identify knee OA-related health care utilization differences. The purpose of this investigation was to evaluate gender differences in the utilization of OA-related health care resources in the 12 months preceding total knee arthroplasty (TKA). METHODS: Truven Health MarketScan Commercial Claims and Encounters and Medicare Supplemental and Coordination of Benefit databases were reviewed from 2005 to 2012. Subjects were included if they underwent TKA, had associated diagnosis of lower leg OA, and were continuously in the database for 12 months preceding TKA. Patient-specific OA-related health care utilization was identified. Multivariate logistic regression analysis controlling for age, region, and Charlson Comorbidity Index was performed to isolate the influence of gender. RESULTS: A total of 244,059 patients with a mean age of 64.8 years consisting of 61.2% women were included. Multivariate logistic regression adjusted odds ratios showed that when compared to men, women were 30%, 20%, 31%, 18%, 19%, 29%, and 39%, more likely to receive a narcotic analgesic, nonnarcotic analgesics, corticosteroid injection, hyaluronic acid injection, knee magnetic resonance imaging, a physical therapy evaluation, and occupational therapy evaluation in the 12 months preceding TKA, respectively. CONCLUSION: Women have a significantly higher utilization of knee OA-related health care in the 12 months preceding TKA. Although the precise cause for this discrepancy in care cannot be determined from this study, it highlights a potential bias in management of advanced knee OA and directions for further investigation.

Effect of Spaceflight and Microgravity on the Musculoskeletal System: A Review.

With National Aeronautics and Space Administration's plans for longer distance, longer duration spaceflights such as missions to Mars and the surge in popularity of space tourism, the need to better understand the effects of spaceflight on the musculoskeletal system has never been more present. However, there is a paucity of information on how spaceflight affects orthopaedic health. This review surveys existing literature and discusses the effect of spaceflight on each aspect of the musculoskeletal system. Spaceflight reduces bone mineral density at rapid rates because of multiple mechanisms. While this seems to be recoverable upon re-exposure to gravity, concern for fracture in spaceflight remains as microgravity impairs bone strength and fracture healing. Muscles, tendons, and entheses similarly undergo microgravity adaptation. These changes result in decreased muscle mass, increased tendon laxity, and decreased enthesis stiffness, thus decreasing the strength of the muscle-tendon-enthesis unit with variable recovery upon gravity re-exposure. Spaceflight also affects joint health; unloading of the joints facilitates changes that thin and atrophy cartilage similar to arthritic phenotypes. These changes are likely recoverable upon return to gravity with exercise. Multiple questions remain regarding effects of longer duration flights on health and implications of these findings on terrestrial medicine, which should be the target of future research.

Forgetting the Frail: National Trends in Vitamin D Prescription After Fragility Fracture-A Large Insurance Claims Database Study.

INTRODUCTION: Vitamin D plays a critical role in bone health, affecting bone mineral density and fracture healing. Insufficient serum vitamin D levels are associated with increased fracture rates. Despite guidelines advocating vitamin D supplementation, little is known about the prescription rates after fragility fractures. This study aims to characterize vitamin D prescription rates after three common fragility fractures in patients older than 50 years and explore potential factors influencing prescription rates. METHODS: The study used the PearlDiver Database, identifying patients older than 50 years with hip fractures, spinal compression fractures, or distal radius fractures between 2010 and 2020. Patient demographics, comorbidities, and vitamin D prescription rates were analyzed. Statistical methods included chi-square analysis and univariate and multivariable analyses. RESULTS: A total of 3,214,294 patients with fragility fractures were included. Vitamin D prescriptions increased from 2.50% to nearly 6% for all fracture types from 2010 to 2020. Regional variations existed, with the Midwest having the highest prescription rate (4.25%) and the West the lowest (3.31%). Patients with comorbidities such as diabetes, tobacco use, obesity, female sex, age older than 60 years, and osteoporosis were more likely to receive vitamin D prescriptions. DISCUSSION: Despite a notable increase in vitamin D prescriptions after fragility fractures, the absolute rates remain low. Patient comorbidities influenced prescription rates, perhaps indicating growing awareness of the link between vitamin D deficiency and these conditions. However, individuals older than 60 years, a high-risk group, were markedly less likely to receive prescriptions, possibly because of practice variations and concerns about polypharmacy. Educational initiatives and revised guidelines may have improved vitamin D prescription rates after fragility fractures. However, there is a need to raise awareness about the importance of vitamin D for bone health, particularly in older adults, and additional study variations in prescription practices. These findings emphasize the importance of enhancing post-fracture care to reduce morbidity and mortality associated with fragility fractures. LEVEL OF EVIDENCE: III.

Orthopaedic residency education: a practical guide to selection, training, and education.

The education of orthopaedic residents is an important responsibility shared by all those involved in residency training. The education of orthopaedic residents begins with the selection process, which recognizes the importance of choosing qualified individuals who can successfully complete the training program. Education during the 5 years of required training entails the acquisition of a body of knowledge, the development of surgical skills, and the exhibition of a level of professionalism consistent with being a physician and surgeon. Residency training also requires an evaluation of performance and, when necessary, measures to improve performance or correct inappropriate behaviors. The goal at the end of the 5-year training period is to have well-qualified, skilled, and knowledgeable orthopaedic surgeons who can enter practice and provide the highest level of patient care.

Reliability and validity of a mobile phone for radiographic assessment of ankle injuries: a randomized inter- and intraobserver agreement study.

BACKGROUND: Current mobile phone technology may allow orthopaedic surgeons to make clinical decisions using radiographs viewed on a small mobile device screen. The purpose of this study was to examine the reliability and validity of interpreting ankle fracture images viewed on a mobile device and a computer monitor, with a hypothesis that the agreement in clinical decision making between the mobile device and computer monitor would be high. METHODS: A randomized interobserver and intraobserver reliability study was conducted in which 16 mortise and lateral ankle images representing a severity spectrum of malleolar ankle, plafond, and extra-articular tibial fractures were shown to volunteer orthopaedic surgeons on both an Apple fourth-generation iPod Touch and a 23-inch liquid crystal display (LCD) computer monitor. Participants answered a multiple-choice questionnaire for each image regarding diagnosis, severity, need for higher level imaging, need for acute inpatient versus outpatient management, and plan of treatment. Inter- and intraobserver reliability was assessed by kappa (κ), multirater kappa statistics, and intraclass correlation coefficient (ICC). RESULTS: Ninety-three orthopaedic surgeon volunteers completed the study. Excellent intraobserver agreement (κ ≥ 0.8) was found for all variables measured, including diagnosis (median κ = 0.84), need for computed tomography scan (κ = 0.86), need for reduction (κ = 0.82), treatment setting (κ = 0.82), and treatment type (κ = 0.87). Interobserver agreement was consistent between the mobile device and computer screen. Interobserver agreement for the severity assessment had a slightly higher ICC for the mobile device compared with the computer monitor (ICC = 0.83 vs 0.79). Sixty-seven percent (62/93) said at the completion of the study they were "completely" or "very" comfortable using a mobile device as a primary viewing device for new emergency room, inpatient, or transfer request consults. CONCLUSIONS: Strong reliability for radiographic assessment of ankle injuries existed between a 23-inch computer monitor and a handheld mobile device. Further study is warranted to validate the technology to apply to other anatomic locations and imaging modalities. LEVEL OF EVIDENCE: Level II, diagnostic study.

Team Approach: Organizing and Empowering Multidisciplinary Teams in Postfragility Fracture Care.

¼ Numerous healthcare roles can be valuable and effective participants in postfracture care programs (PFCPs) and can also serve effectively as program liaisons/champions.¼ Greatest success seems to have been achieved when a single entity provides cohesive and consistent training, coordination, shared goals, and accountability for program sites and site leaders.¼ Few PFCPs have solved what seems to be the fundamental challenge of such programs: how to maintain program effectiveness and cohesion when the patient makes the inevitable transition from acute care to primary care? Creating a partnership with shared goals with primary care providers is a challenge for every program in every location.¼ Programs located in the United States, with its predominantly "open" healthcare system, seem to lag other parts of the world in overcoming this fundamental challenge.¼ It is hoped that all PFCPs in all systems can learn from the successes of other programs in managing this critical transition from acute to primary care.

Fracture healing-orthobiologics: from basic science to clinical application.

Orthopaedics as a field and a profession is fundamentally concerned with the treatment of musculoskeletal disease, in all of its many forms. Our collective understanding of the cellular mechanisms underlying musculoskeletal pathology resulting from injury continues to evolve, opening novel opportunities to develop orthobiologic treatments to improve care. It is a long path to move from an understanding of cellular pathology to development of successful clinical treatment, and this article proposes to discuss some of the challenges to achieving translational therapies in orthopaedics. The article will focus on challenges that clinicians will likely face in seeking to bring promising treatments forward to clinical practice and strategies for improving success in translational efforts.

Practical research methods for orthopaedic surgeons.

Inherent to understanding an orthopaedic study is a fundamental knowledge of the study's design principles and statistics. Statistics, in part, allow a researcher to sample a portion of the population and use probability to decide whether the findings from the sample are likely to apply to the whole population. Although statistical jargon can be confusing, several simple principles guide the approach to research design. It is helpful for orthopaedic surgeons to review different study designs and their levels of evidence, to understand statistical jargon and the selection of the statistical test that is appropriate for given types of data, and to be familiar with the process of sample size calculations. Knowledge gained from statistical principles and research design is used to interpret study results. Such knowledge is invaluable for judging the value of new clinical evidence and for designing future studies.

Best Practice Guidelines for Assessment and Management of Osteoporosis in Adult Patients Undergoing Elective Spinal Reconstruction.

STUDY DESIGN: Expert consensus study. OBJECTIVE: This expert panel was created to establish best practice guidelines to identify and treat patients with poor bone health prior to elective spinal reconstruction. SUMMARY OF BACKGROUND DATA: Currently, no guidelines exist for the management of osteoporosis and osteopenia in patients undergoing spinal reconstructive surgery. Untreated osteoporosis in spine reconstruction surgery is associated with higher complications and worse outcomes. METHODS: A multidisciplinary panel with 18 experts was assembled including orthopedic and neurological surgeons, endocrinologists, and rheumatologists. Surveys and discussions regarding the current literature were held according to Delphi method until a final set of guidelines was created with over 70% consensus. RESULTS: Panelists agreed that bone health should be considered in every patient prior to elective spinal reconstruction. All patients above 65 and those under 65 with particular risk factors (chronic glucocorticoid use, high fracture risk or previous fracture, limited mobility, and eight other key factors) should have a formal bone health evaluation prior to undergoing surgery. DXA scans of the hip are preferable due to their wide availability. Opportunistic CT Hounsfield Units of the vertebrae can be useful in identifying poor bone health. In the absence of contraindications, anabolic agents are considered first line therapy due to their bone building properties as compared with antiresorptive medications. Medications should be administered preoperatively for at least 2 months and postoperatively for minimum 8 months. CONCLUSION: Based on the consensus of a multidisciplinary panel of experts, we propose best practice guidelines for assessment and treatment of poor bone health prior to elective spinal reconstructive surgery. Patients above age 65 and those with particular risk factors under 65 should undergo formal bone health evaluation. We also established guidelines on perioperative optimization, utility of various diagnostic modalities, and the optimal medical management of bone health in this population.Level of Evidence: 5.

Applied biomechanics in articular injuries: perspectives in the basic investigation of articular injuries and clinical application.

Joint injury is an important cause of arthritis. Although the treatment of injury, in general, has been widely studied, the contribution of injury to the development of posttraumatic arthritis is still a relatively understudied area. One of the most perplexing aspects of investigating articular injuries is the complex nature of the injury itself and the multiple facets of the injury mechanism that can potentially lead to the development of arthritis. A symposium by the Orthopaedic Research Society and the American Academy of Orthopaedic Surgeons was designed to examine the spectrum of basic science to clinical investigation in the role of biomechanics in the study of joint injury and subsequent posttraumatic arthritis. Four perspectives in the clinical aspects of managing articular injuries were investigated, including the clinical applications of basic science findings, the challenges and advancements in measuring and modeling articular fractures, the relationship of articular cartilage mechanical injuries and osteoarthritis, and the controlled creation of an intra-articular fracture to permit observations of the natural history of posttraumatic arthritis.

Impact of Level of Evidence on Citation of Orthopaedic Articles.

INTRODUCTION: Level of evidence grading has become widely used in orthopaedics. This study reviewed clinical research articles published in leading orthopaedic journals to describe the association between level of evidence and number of future citations, which is one measure of an article's impact in the field. METHODS: The first 100 clinical research articles published in 2014 by each of the Journal of Bone and Joint Surgery, Clinical Orthopaedics and Related Research, and the American Journal of Sports Medicine were reviewed for level of evidence and article characteristics. Web of Science was used to identify the number of citations of each article over the following 5 years. Univariable analyses and multivariable linear regression were used to describe the associations. RESULTS: Three hundred articles were evaluated. Univariable analysis revealed no association between level of evidence and number of citations, with a median number of citations for level 1 articles of 23 (interquartile range [IQR], 14-49), level 2 articles 24 (IQR, 13-47), level 3 articles 22 (IQR, 13-40), and level 4 or 5 articles 20 (IQR, 10-36). Univariable analyses showed weak associations between other article characteristics and citations. Even after adjusting for other variables, the standardized regression coefficient for level 1 versus level 4 or 5 was only 0.14 and the overall model had a poor fit with an R2 of 0.18. CONCLUSIONS: Among clinical research articles published in leading orthopaedic journals, no notable association was found between level of evidence and future citations. CLINICAL RELEVANCE: Readers of the orthopaedic literature should understand that no association was found between level of evidence and future citations. Additional work is needed to better understand the effect level of evidence has on clinicians and researchers.

Ballistic Supracondylar Distal Femur Fractures Have Lower Rates of Intra-articular Extension Than Blunt Distal Femur Fractures.

OBJECTIVES: To compare the relative frequencies of intra-articular extension of supracondylar distal femur fractures in blunt versus ballistic trauma and the diagnostic accuracy of conventional radiography in identifying intra-articular extension in these fractures. DESIGN: A retrospective review. SETTING: Urban academic trauma center. STUDY GROUP: Thirty-eight patients were included for analysis, with 19 blunt and 19 ballistic mechanism distal femur fractures. INTERVENTION: Fleiss' kappa score was calculated in determining interobserver reliability of the OTA/AO classification. Radiographic specificity and sensitivity were compared using Fischer exact testing. Quantitative data were compared using 2-tailed t-testing for continuous variables and chi-square tests for proportions. MAIN OUTCOME MEASUREMENTS: Rate of intra-articular extension of ballistic versus blunt supracondylar femur fractures. RESULTS: Seventeen of 19 patients (89.5%) with blunt trauma had intra-articular involvement compared with 5 of 19 patients (26.3%) with ballistic trauma (P = 0.001). For blunt fractures, preoperative radiographs were 94% sensitive for the detection of intra-articular extension compared with 100% sensitive for ballistic fractures (P = 1.000). We identified one case, in the blunt cohort, where the operative plan changed from intramedullary nail to open reduction and internal fixation as a result of the additional coronal plane fracture pattern identified on CT. There were no such occurrences in the ballistic cohort. CONCLUSIONS: The rate of intra-articular extension for ballistic supracondylar femur fractures is lower than blunt distal femur fracture. There were low rates of missed intra-articular fractures and changes in operative plans after reviewing CT imaging for both blunt and ballistic distal femur fractures. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Do 30-Day Reoperation Rates Adequately Measure Quality in Orthopedic Surgery?

BACKGROUND: Unplanned reoperation rates represent an important metric in monitoring quality in orthopedic surgery. Previous studies have focused on 30-day reoperation rates, not accounting for complications that may arise beyond this time. This study aimed to understand the frequency, timing, and procedure type of orthopedic reoperations, as well as the complications leading up to these reoperations over a 1-year period. METHODS: A single-center, retrospective cohort study reviewed all orthopedic surgeries performed within a three-year period and subsequently identified reoperations within a year following the initial case. Exclusion criteria for reoperations included those that were planned, involved a different body part, or had a different laterality from the first operation. The cases were analyzed by procedure type, timing of reoperation, and causes of reoperation. RESULTS: Of the 10,449 orthopedic surgeries performed between 2012 and 2015, 947 (9.1%) were unplanned reoperations within 1 year. Most (775; 81.8%) unplanned reoperations occurred after 30 days. Infections/wound complications (58.2%) were the most common reason for unplanned reoperations at 1 month from the initial operation, and mechanical complications (49.5%) predominated at the 6-months-to-1-year time frame. CONCLUSION: This study demonstrated that the current paradigm of focusing on reoperations occurring within 30 days of the initial operation captures only a fraction of unplanned reoperations. Stratification of this metric by time and precipitating complication type provides additional information that quality improvement programs may target. A 1-year unplanned reoperation rate could be used as a broad indicator of surgical quality across institutions.

Secondary Fracture Prevention: Consensus Clinical Recommendations from a Multistakeholder Coalition.

Osteoporosis-related fractures are undertreated, due in part to misinformation about recommended approaches to patient care and discrepancies among treatment guidelines. To help bridge this gap and improve patient outcomes, the American Society for Bone and Mineral Research assembled a multistakeholder coalition to develop clinical recommendations for the optimal prevention of secondary fracture among people aged 65 years and older with a hip or vertebral fracture. The coalition developed 13 recommendations (7 primary and 6 secondary) strongly supported by the empirical literature. The coalition recommends increased communication with patients regarding fracture risk, mortality and morbidity outcomes, and fracture risk reduction. Risk assessment (including fall history) should occur at regular intervals with referral to physical and/or occupational therapy as appropriate. Oral, intravenous, and subcutaneous pharmacotherapies are efficacious and can reduce risk of future fracture. Patients need education, however, about the benefits and risks of both treatment and not receiving treatment. Oral bisphosphonates alendronate and risedronate are first-line options and are generally well tolerated; otherwise, intravenous zoledronic acid and subcutaneous denosumab can be considered. Anabolic agents are expensive but may be beneficial for selected patients at high risk. Optimal duration of pharmacotherapy is unknown but because the risk for second fractures is highest in the early post-fracture period, prompt treatment is recommended. Adequate dietary or supplemental vitamin D and calcium intake should be assured. Individuals being treated for osteoporosis should be reevaluated for fracture risk routinely, including via patient education about osteoporosis and fractures and monitoring for adverse treatment effects. Patients should be strongly encouraged to avoid tobacco, consume alcohol in moderation at most, and engage in regular exercise and fall prevention strategies. Finally, referral to endocrinologists or other osteoporosis specialists may be warranted for individuals who experience repeated fracture or bone loss and those with complicating comorbidities (eg, hyperparathyroidism, chronic kidney disease). © 2019 American Society for Bone and Mineral Research.

Hemorrhage in pelvic fractures does not correlate with fracture length.

BACKGROUND: To analyze whether hematogenous marrow bleeding is the major source of hemorrhage after fractures of the pelvic ring. DESIGN: Retrospective cohort study. SETTING: Academic Level I trauma center. PATIENTS OR PARTICIPANTS: Three hundred seven consecutive pelvic ring injuries from January 1, 2000 to December 31, 2003 were evaluated. After exclusion for age, significant nonpelvic hemorrhage sources, and delayed transfer to this institution, 72 patients remained. MAIN OUTCOME MEASUREMENTS: Pelvic injuries were classified as fractures, fracture dislocations, or pure dislocations. These classifications were correlated to change in hematocrit between assumed preinjury and final hematocrit readings, correcting for blood transfused. RESULTS: The dislocation group had a greater change in hematocrit than the fracture group (2.1%), though not statistically significant. No significant correlations were found between change in hematocrit and length of fracture lines. CONCLUSIONS: Pelvic fracture surfaces may be sources of bleeding in pelvic injuries, but the fact that bleeding is similar in fractures and dislocations indicates fracture surfaces do not constitute the primary source. Based on our analysis one cannot reliably predict pelvic hemorrhage based on A/P radiograph assessments, such as fracture type.

Orthopaedic faculty trauma call policies: a survey of accredited orthopaedic residency programs.

The purpose of the study was to determine the practices and policies for trauma call for orthopaedic faculty at residency training programs. A 2-page survey was mailed to the chairs of 141 nonmilitary, accredited residency programs. Responses were received from 106 (75% response rate). Of the responders, 97 (91.5%) of the programs were associated with a Level 1 trauma center. All faculty took trauma call in 44% of programs. The chair took trauma call in 60% of the programs. In 35% of programs, full-time faculty earned additional compensation for taking call. The source of this compensation for full-time faculty was the hospital alone in 72%. In 32 programs, a per-diem stipend (mean $696, range $100-1,500) was provided. In 59% of programs, there was a specific orthopaedic "trauma team" that took over patient care from other faculty members after call. Thirty-three percent of programs had a policy concerning age when a full-time faculty member went off trauma call. Of these, faculty came off call at age 50 years in 11% of programs; at age 55 years in 29%; at age 60 years in 40%; at age 65 years in 9%; and "other" in 11%. Twenty percent of chairs responded that trauma call adversely affected the chair's ability to recruit new faculty. There was a wide variety of policies concerning orthopaedic faculty trauma call. Additional studies on faculty trauma call are warranted.
