OBJECTIVES: The goals of this study were to investigate trends in the timing to femur fracture fixation in trauma centers in the United States, identify predictors for delayed treatment, and analyze the association of timing to fixation with in-hospital morbidity and mortality using data from the National Trauma Data Bank (NTDB). METHODS: Patients with femoral shaft fractures treated from 2007–2015 were identified from the NTDB, and grouped by timing of femur fixation: 48 hours after hospital presentation. The primary outcome measure was in-hospital postoperative mortality rate. Secondary outcomes included complication rates, length of hospital stay (LOS), days spent in the intensive care unit (ICU LOS), and days on a ventilator. RESULTS: Among the 108,825 unilateral femoral shaft fractures identified, 74.2% were fixed within 24 hours, 16.5% between 24–48 hours, and 9.4% >48 hours. The mortality rate was 1.6% overall for the group. When fixation was delayed >48 hours, patients were at risk of significantly higher mortality rate (OR 3.60; 95% confidence interval [CI], 3.13–4.14), longer LOS (OR 2.14; CI 2.06–2.22), longer ICU LOS (OR 3.92; CI 3.66–4.20), more days on a ventilator (OR 5.38; CI 4.89–5.91), and more postoperative complications (OR 2.05; CI 1.94–2.17; p48 hours after presentation were at the greatest risk for increased morbidity and mortality. Although some patients require optimization/resuscitation prior to fracture fixation, efforts should be made to expedite operative fixation. LEVEL OF EVIDENCE: Prognostic Level III.

Objectives To report the progression of radiographic healing after intramedullary nailing of tibial shaft fractures using the Radiographic Union Score for Tibial fractures (RUST) and determine the ideal timing of early post-operative radiographs. Design Retrospective case series. Setting Urban academic Level 1 trauma center. Patients/participants 303 acute tibial shaft fractures underwent intramedullary nailing between 2006-2013, met inclusion criteria, and had at least three months of radiographic follow-up. Intervention Baseline demographic, injury, and surgical data were recorded for each patient. Each set of post-operative radiographs were scored using RUST and evaluated for implant failure. Main outcome measurements Post-operative time distribution for each RUST score, RUST score distribution for four common follow-up time points, and the presence and timing of implant failure. Results The 5th percentile and median times, respectively for reaching: "any radiographic healing" (RUST= 5) was 4.0 weeks and 8.4 weeks, "radiographically healed" (RUST=9) was 12.1 and 20.9 weeks, and "healed and remodeled" (RUST=12) was 23.5 weeks and 47.7 weeks. At six weeks, 84% of radiographs were scored as RUST≤6 (two or fewer cortices with callus). No implant failure occurred within the first eight weeks after surgery and the indication for all seven reoperations within this period was apparent on physical examination or immediate post-operative radiographs. Conclusions The median time to radiographic union (RUST=9) after tibial nailing was approximately twenty weeks and little radiographic healing occurred within the first eight weeks after surgery. Routine radiographs in this time period may offer little additional information in the absence of clinical concerns such as new trauma, malalignment, or infection.

Objective To report on the incidence of surgical wound complications after percutaneous posterior pelvic ring fixation in patients who have also undergone pelvic arterial embolization (PAE) and determine whether the risks outweigh the benefits. Design Retrospective cohort study. Setting Academic level 1 trauma center. Patients Two hundred one consecutive patients who underwent percutaneous posterior pelvic fixation at our institution were included in this study. Of these, 27 patients underwent pelvic arterial embolization. Intervention Percutaneous posterior pelvic fixation and pelvic arterial embolization. Main outcome measurements Charts were reviewed for posterior percutaneous surgical wound complications including infection, dehiscence, seroma, tissue necrosis, and return to OR for debridement in all patients. Results Of the 27 patients who received PAE, none developed posterior surgical wound complications. Of those who did not receive PAE, there was one posterior surgical wound complication documented. There were no cases of wound infection in either group. Conclusion Pelvic arterial embolization can be a valuable intervention in treating hemodynamically unstable patients with pelvic ring injuries. Although even selective pelvic arterial embolization is not entirely benign, there seems to be minimal risk of wound complications when percutaneous posterior pelvic ring fixation is performed.

Background Adult septic arthritis can be challenging to differentiate from other causes of acute joint pain. The diagnostic accuracy of synovial lactate and polymerase chain reaction (PCR) remains uncertain. Objective Our aim was to quantify the diagnostic accuracy of synovial lactate, PCR, and clinical evaluation for adults with possible septic arthritis in the emergency department (ED). Methods We report a prospective sampling of ED patients aged ≥ 18 years with knee symptoms concerning for septic arthritis. Clinicians and research assistants independently performed history and physical examination. Serum and synovial laboratory testing was ordered at the discretion of the clinician. We analyzed frozen synovial fluid specimens for l - and d -lactate and PCR. The criterion standard for septic arthritis was bacterial growth on synovial culture and treated by consultants with operative drainage, prolonged antibiotics, or both. Diagnostic accuracy measures included sensitivity, specificity, likelihood ratios, interval likelihood ratios, and receiver operating characteristic area under the curve. Results Seventy-one patients were included with septic arthritis prevalence of 7%. No finding on history or physical examination accurately ruled in or ruled out septic arthritis. Synovial l - and d -lactate and PCR were inaccurate for the diagnosis of septic arthritis. Synovial white blood cell count and synovial Gram stain most accurately rule in and rule out septic arthritis. Conclusions Septic arthritis prevalence in ED adults is lower than reported previously. History and physical examination, synovial lactate, and PCR are inadequate for the diagnosis of septic arthritis. Synovial white blood cell count and Gram stain are the most accurate tests available for septic arthritis.

Illness beliefs are significant contributors to health outcomes. Beliefs about the cause of physical symptoms are considered particularly important among those with medically unexplained symptoms and illnesses (MUS); yet little is known about causal beliefs among those with the most severe MUS (i.e., Veterans). The goal of the current study was to examine Veteran's causal attributions of their physical symptoms. A total of 91 combat Veterans with MUS were surveyed using a mixed-methods design about the cause of their physical symptoms, physical symptom severity, and PTSD symptoms. Causal attributions of physical symptoms were analyzed through thematic response analysis and grouped into categories. Chi-square analysis was used to assess the distribution of causal attribution types across Veterans with varying physical symptom severity and PTSD symptom severity. Veterans with MUS reported an average of 7.9 physical symptoms, and attributed the cause of their symptoms to seven different categories (“Do not Know,” “Stress/Mental Health,” “Deployment/Environment,” “Functional/Symptom,” “Medically Explained,” “Medically Unexplained Syndrome,” and “Lifestyle”). Exploratory chi-square analysis revealed significant differences in causal attributions across physical symptom severity and severity of PTSD symptoms. Veterans with more severe PTSD and Veterans with more severe physical symptoms were more likely to attribute their MUS to stress/mental health or to a medically unexplained syndrome compared with those with low/no PTSD symptoms and physical symptom severity. Veterans with minimal PTSD and Veterans with minimal physical symptom severity were more likely to attribute the cause of their MUS to lifestyle choices (e.g., exercise/diet) compared with those with high PTSD and physical symptom severity. Veterans with MUS endorse multiple, varied causal attributions for their physical symptoms, suggesting more complex causal beliefs than typically assumed. This has important implications for patient-provider communication and development of concordance around MUS treatment.

Medically unexplained syndromes (MUS) are both prevalent and disabling. While illness beliefs and behaviors are thought to maintain MUS-related disability, little is known about which specific behavioral responses to MUS are related to disability or the way in which beliefs and behaviors interact to impact functioning. The purpose of the present study was to examine the relationship between illness beliefs and disability among patients with MUS, and assess the extent to which behaviors mediate this relationship. The study examined data from the baseline assessment of a multi-site randomized controlled trial (RCT). Participants were 248 veterans with MUS. Illness beliefs, behavioral responses to illness, and disability were assessed through self-report questionnaire. Data were analyzed using mediation analysis. Threat-related beliefs predicted greater disability through decreased activity and increased practical support seeking. Protective beliefs predicted less disability through reductions in all-or-nothing behavior and limiting behavior. These outcomes suggest that all-or-nothing behavior, limiting behavior, and practical support seeking are important in the perpetuation of disability among those with MUS. This has implications for improving MUS treatment by highlighting potential treatment targets. ClinicalTrials.gov Identifier: NCT02161133

Objectives To determine stability of 2-part intertrochanteric femur fractures and to determine whether secondary collapse is related to fixation method. Design A retrospective cohort series. Setting Single Level I Trauma Center. Patients One hundred fourteen patients (82 female) older than 50 years (average age 75 years, range 50-100 years) with an acute low-energy standard obliquity 2-part intertrochanteric femur fracture (OTA/AO 31A) identified from an orthopaedic trauma database were studied. Intervention Twenty-three patients were treated with a sliding hip screw (dynamic hip screw [DHS]), 53 with a dual screw trochanteric entry nail (INTERTAN), and 38 with a single-blade or screw trochanteric entry intramedullary nail (trochanteric fixation nail [TFN]) based on surgeon choice by 4 fellowship-trained orthopaedic trauma surgeons. Main outcome measures Fracture collapse was measured by comparing immediate postoperative radiographs to those at final follow-up while controlling for magnification and rotation. Results Collapse averaged 6.8 mm in the DHS group, 3.7 mm in the INTERTAN group, and 7.3 mm in the TFN group. When comparing groups, there was significantly more collapse in the DHS group compared with the INTERTAN group (P = 0.021), and significantly more collapse in the TFN group compared with the INTERTAN group (P 10-mm collapse including 4 (17%) with greater than 20-mm collapse (max = 34.2 mm). Four patients (8%) in the INTERTAN group had >10-mm collapse and none had greater than 12.9 mm. Ten patients (26%) in the TFN group had >10-mm collapse and 3 (5%) had greater than 20-mm collapse (max = 30.7 mm). Conclusion Stability of 2-part intertrochanteric femur fractures is dependent on the fixation device. These fractures are not necessarily stable when treated with a sliding hip screw as 26% treated with this method collapsed greater than 10 mm and 17% more than 20 mm. Dual screw intramedullary nail fixation seems to be most effective to maintain stability for patients with this fracture pattern. Level of evidence Prognostic Level III.

We developed the System for Observing Medical Alliances (SOMA) to study relationships between medical providers and patients with medically unexplained symptoms (MUS). Based on literature in health psychology, medicine, and the psychotherapeutic alliance, the SOMA operationalizes three medical alliance dimensions: Engagement in the Consultation Process, Trust in the Provider, and Concordance of Illness Beliefs and Treatment Recommendations. Specific behavioral indicators, tallied as observed by trained judges, are used as the basis for rating each dimension. In a sample of 33 medical consultations with veterans who had MUS, interrater reliabilities ranged from .79 to .94. Notably, the other dimension ratings accounted for 40% of the variability in Concordance, with Trust in the Provider contributing unique variance. In addition to research, psychologists in integrated health settings can use the SOMA to consult and train medical providers on communication skills that enhance concordance.

Medically unexplained symptoms (MUS) are common among veterans and are difficult to treat. Optimal treatment entails continued care from providers, including primary care and counseling psychologists. Non-concordance between veterans' and providers' views of MUS may contribute to poor veteran satisfaction with care and possibly disengagement with care (e.g., non-adherence to treatment recommendations, including counseling and graded exercise). The current study surveyed 243 veterans with MUS post-deployment and evaluated the degree of non-concordance perceived by veterans with their primary care providers regarding their MUS and the effect of perceived non-concordance on treatment behaviors and outcomes. Many veterans in the current sample perceived non-concordance with their provider regarding their MUS (19% reporting quite a bit or complete disagreement). Perceived non-concordance (regarding MUS overall and specific causal perceptions) predicted important outcomes of interest, particularly veterans' satisfaction with their provider. Perceived concordance with primary care doctors may be required for sufficient adherence to MUS treatment recommendations, such as seeking and maintaining psychological counseling. Research should evaluate the effect of perceived concordance with the counseling psychologist on adherence to and outcomes from counseling for MUS.

Medically unexplained symptoms and/or syndromes (MUS) affect the health of 20% to 30% of patients seen in primary care. Optimally, treatment for these patients requires an interdisciplinary team consisting of both primary care and mental health providers. We propose that counseling psychologists may develop expertise to improve the care of patients with MUS who are already in their practice, expand the number of patients they help, and enhance the integration of counseling psychology into the broader medical community. Additionally, counseling psychologists’ expertise in culture, attunement to therapeutic processes, and focus on prioritizing patients’ perspectives and quality of life can fill the gap in research on MUS. By focusing on MUS, counseling psychologists can provide unique contributions to health service delivery.

The purpose of this study was to survey trauma and arthroplasty surgeons to investigate associations between subspecialty training and management of geriatric femoral neck fractures and to compare treatments with the American Academy of Orthopaedic Surgeons clinical practice guidelines.Five hundred fifty-six surgeons completed the online survey consisting of two sections: (1) surgeon demographics and (2) two geriatric hip fracture cases with questions regarding treatment decisions.In both clinical scenarios, arthroplasty surgeons were more likely than trauma surgeons to recommend total hip arthroplasty (THA) (case 1: 96% versus 84%; case 2: 29% versus 10%; P ≤ 0.02) and spinal anesthesia (case 1: 70% versus 40%; case 2: 62% versus 38%; P0.01). Surgeons who have made changes based on clinical practice guidelines (n = 96; 21% of surveyed) cited more use of THA (n = 56; 58% of respondents) and cemented stems (n = 28; 29% of respondents).Arthroplasty surgeons are more likely to recommend THA over hemiarthroplasty and have a higher expectation for spinal anesthesia for the management of geriatric femoral neck fractures.

BACKGROUND: Delayed diagnoses of unstable thoracolumbar-spine (TL-spine) fractures can result in neurological deficits and avoidable pain, so it is important for clinicians to reach prompt diagnostic decisions. There are no validated decision aids for determining which trauma patients warrant TL-spine imaging. OBJECTIVES: Quantifying the diagnostic accuracy of the injury mechanism, physical examination, associated injuries, clinical decision aids, and imaging for evaluating blunt TL-spine trauma patients. METHODS: A search strategy for studies including adult blunt TL-spine trauma using PubMed, Embase, Scopus, CENTRAL, Cochrane Database of Systematic Reviews, and ClinicalTrials.gov was performed. Excluded studies lacked data to construct 2×2 tables, were duplicates, not primary research, did not focus on blunt trauma, examined associated injuries without any utility in identifying TL-spine injuries, only studied cervical-spine fractures, were non-English, had a pediatric setting, or were cadaver/autopsy reports. Risk of bias was assessed using the Quality Assessment Tool for Diagnostic Accuracy Studies. Diagnostic predictors were analyzed with a meta-analysis of sensitivity, specificity, and likelihood ratios. RESULTS: In blunt trauma patients in the emergency department, the weighted pretest probability of a TL-spine fracture was 15%. The estimates for the detection of TL-spine fractures with plain film was positive likelihood ratio (+LR)=25.0 (95% CI=4.1-152.2, I2=94%, p

Importance Despite the widespread use of systemic antibiotics to prevent infections in surgically treated patients with fracture, high rates of surgical site infection persist. Objective To examine the effect of intrawound vancomycin powder in reducing deep surgical site infections. Design, Setting, and Participants This open-label randomized clinical trial enrolled adult patients with an operatively treated tibial plateau or pilon fracture who met the criteria for a high risk of infection from January 1, 2015, through June 30, 2017, with 12 months of follow-up (final follow-up assessments completed in April 2018) at 36 US trauma centers. Interventions A standard infection prevention protocol with (n = 481) or without (n = 499) 1000 mg of intrawound vancomycin powder. Main Outcomes and Measures The primary outcome was a deep surgical site infection within 182 days of definitive fracture fixation. A post hoc comparison assessed the treatment effect on gram-positive and gram-negative-only infections. Other secondary outcomes included superficial surgical site infection, nonunion, and wound dehiscence. Results The analysis included 980 patients (mean [SD] age, 45.7 [13.7] years; 617 [63.0%] male) with 91% of the expected person-time of follow-up for the primary outcome. Within 182 days, deep surgical site infection was observed in 29 of 481 patients in the treatment group and 46 of 499 patients in the control group. The time-to-event estimated probability of deep infection by 182 days was 6.4% in the treatment group and 9.8% in the control group (risk difference, –3.4%; 95% CI, –6.9% to 0.1%;P = .06). A post hoc analysis of the effect of treatment on gram-positive (risk difference, –3.7%; 95% CI, –6.7% to –0.8%;P = .02) and gram-negative-only (risk difference, 0.3%; 95% CI, –1.6% to 2.1%;P = .78) infections found that the effect of vancomycin powder was a result of its reduction in gram-positive infections. Conclusions and Relevance Among patients with operatively treated tibial articular fractures at a high risk of infection, intrawound vancomycin powder at the time of definitive fracture fixation reduced the risk of a gram-positive deep surgical site infection, consistent with the activity of vancomycin.

Highlights • Risk communication for viruses can be efficacious. • Results highlight the complexities of risk communication. • Risk communication for HIV/AIDS was more consistently efficacious as compared to influenza. • Various risk communication approaches were effective. • Tailoring risk communication to a population may be more efficacious., Objective In response to COVID-19, we conducted a rapid review of risk communication interventions to mitigate risk from viruses to determine if such interventions are efficacious. Methods We searched for risk communication interventions in four databases: Medline, PsycInfo, the ProQuest Coronavirus Research Database, and CENTRAL. The search produced 1572 articles. Thirty-one articles were included in the final review. Results Results showed risk communication interventions can produce cognitive and behavior changes around viruses. Results were more consistently positive for interventions focused on HIV/AIDS as compared to influenza. There was no consistent best intervention approach when comparing peer health, audio/visual, and intensive multi-media interventions. Tailoring risk communication toward a target population, in comparison to not tailoring, was related to better outcomes. Conclusion The results suggest that risk communication interventions can be efficacious at reducing risk from viruses. They also highlight the complexity of risk communication interventions. Additional research is needed to understand the mechanisms that lead risk communication to reduce risk from viruses. Practical value Results support risk communication interventions to reduce risk from viruses.

Aims Gulf War Illness (GWI) is a prevalent and disabling condition characterized by persistent physical symptoms. Clinical practice guidelines recommend self-management to reduce the disability from GWI. This study evaluated which GWI self-management strategies patients currently utilize and view as most effective and ineffective. Materials and methods Data were collected from 267 Veterans during the baseline assessment of a randomized clinical trial for GWI. Respondents answered 3 open-ended questions regarding which self-management strategies they use, view as effective, and view as ineffective. Response themes were coded, and code frequencies were analyzed. Key findings Response frequencies varied across questions (in-use: n = 578; effective: n = 470; ineffective: n = 297). Healthcare use was the most commonly used management strategy (38.6% of 578), followed by lifestyle changes (28.5% of 578), positive coping (13% of 578), and avoidance (13.7% of 578). When asked about effective strategies, healthcare use (25.9% of 470), lifestyle change (35.7% of 470), and positive coping (17.4% of 470) were identified. Avoidance was frequently identified as ineffective (20.2% of 297 codes), as was invalidating experiences (14.1% of 297) and negative coping (10.4% of 297). Significance Patients with GWI use a variety of self-management strategies, many of which are consistent with clinical practice guidelines for treating GWI, including lifestyle change and non-pharmacological strategies. This suggests opportunities for providers to encourage effective self-management approaches that patients want to use.

We describe a clinical trial which is seeking to determine the effectiveness and understand implementation outcomes for tele-collaborative specialty care for Veterans with Gulf War Illness (GWI).This study will be a hybrid type 1 randomized effectiveness-implementation trial comparing tele-collaborative specialty care to electronic consultation for Gulf War Veterans with GWI (N = 220). In tele-collaborative specialty care, the specialty provider team will deliver health coaching and problem-solving treatment to Veterans and recommend a plan for analgesic optimization. In electronic consultation, the specialty provider team will make a one-time recommendation to the primary care team for locally delivered health coaching, problem-solving treatment and analgesic optimization. The primary aim will be to determine the effectiveness of tele-collaborative specialty care as compared to electronic consultation to reduce disability related to GWI. Our secondary aim will be to understand implementation outcomes.There is a need to improve care for Veterans with GWI. A potentially useful model to improve care is tele-collaborative specialty care, where the specialists work with the primary care provider to synergistically treat the patients.This is the first clinical trial to prospectively compare different models of care for Veterans with GWI. This responds to multiple calls for research to improve treatment for Veterans with GWI, including from the National Academy of Medicine.

SUMMARY Skeletal traction is a fundamental tool for the orthopaedic surgeon caring for patients with traumatic pelvic and lower-extremity orthopaedic injuries. Skeletal traction has proven to be an effective initial means of stabilization in patients with these injuries. Traction may be used for both temporary and definitive treatment in a variety of orthopaedic injuries. With the appropriate knowledge of regional anatomy, skeletal traction pins can be placed safely and with a low rate of complications. Several methods for placing skeletal traction have been described, and it is critical for orthopaedic surgeons to be proficient not only in their application but also understanding of the appropriate indications for use. Here we present a case example of a patient with a right femur fracture and discuss the technique and indications for placement of proximal tibia skeletal traction.

Adequate surgical exposure is necessary for anatomical reduction and fixation of posterior wall acetabular fractures. This video demonstrates the Kocher-Langenbeck approach to the posterior acetabulum, as well as operative indications, surgical reduction and fixation techniques, and outcomes for posterior wall acetabular fractures.

Background Between 10 and 50% of primary care patients present with persistent physical symptoms (PPS). Patients with PPS tend to utilize excessive or inappropriate health care services, while being stuck in a deleterious cycle of inactivity, deconditioning, and further worsening of symptoms and disability. Since military deployment (relative to non-deployment) is associated with greater likelihood of PPS, we examined the interrelationships of health care utilization, symptom burden and functioning among a sample of recently deployed Veterans with new onset persistent physical symptoms. Methods This study analyzed a cohort of 790 U.S. soldiers who recently returned from deployment to Iraq or Afghanistan. Data for this analysis were obtained at pre- and post-deployment. We used moderation analyses to evaluate interactions between physical symptom burden and physical and mental health functioning and four types of health care utilization one-year after deployment, after adjusting for key baseline measures. Results Moderation analyses revealed significant triple interactions between physical symptom burden and health functioning and: primary care (F = 3.63 [2, 303], R2Δ = .02, p = 0.03), specialty care (F = 6.81 [2, 303] R2Δ =0.03, p F = 3.76 [2, 302], R2Δ = .02, p = 0.02), but not mental health care (F = 1.82 [1, 303], R2Δ = .01, p = .16), one-year after deployment. Conclusions Among U.S. Veterans with newly emerging persistent physical symptoms one-year after deployment, increased physical symptom burden coupled with decreased physical and increased mental health functioning was associated with increased medical care use in the year after deployment. These findings support whole health initiatives aimed at improving health function/well-being, rather than merely symptom alleviation.

Nitrogen-containing bisphosphonates (N-BPs), such as alendronate, are the most widely prescribed medications for diseases involving bone, with nearly 200 million prescriptions written annually. Recently, widespread use of N-BPs has been challenged due to the risk of rare but traumatic side effects such as atypical femoral fracture (AFFs) and osteonecrosis of the jaw (ONJ). N-BPs bind to and inhibit farnesyl diphosphate synthase (FDPS), resulting in defects in protein prenylation. Yet it remains poorly understood what other cellular factors might allow N-BPs to exert their pharmacological effects. Here, we performed genome-wide studies in cells and patients to identify the poorly characterized gene, ATRAID. Loss of ATRAID function results in selective resistance to N-BP-mediated loss of cell viability and the prevention of alendronate-mediated inhibition of prenylation. ATRAID is required for alendronate inhibition of osteoclast function, and ATRAID-deficient mice have impaired therapeutic responses to alendronate in both postmenopausal and senile (old age) osteoporosis models. Lastly, we performed exome sequencing on patients taking N-BPs that suffered ONJ or an AFF. ATRAID is one of three genes that contain rare non-synonymous coding variants in patients with ONJ or AFF that is also differentially expressed in poor outcome groups of patients treated with N-BPs. We functionally validated this patient variation in ATRAID as conferring cellular hypersensitivity to N-BPs. Our work adds key insight into the mechanistic action of N-BPs and the processes that might underlie differential responsiveness to N-BPs in people.One Sentence SummaryATRAID is essential for responses to the commonly prescribed osteoporosis drugs nitrogen-containing bisphosphonates.OverlineBONE

Military service presents unique challenges and opportunities for health care and public health. In the USA, there are over 2 million military servicemembers, 20 million veterans, and millions more military and veteran family members. Military servicemembers and eligible family members, many veterans, and retirees receive health care through the two largest learning health care systems in the USA, managed and delivered through the Departments of Defense (DoD), Veterans Affairs (VA), and contracted health care organizations. Through a network of collaborative relationships, DoD, VA, and partnering health care and research organizations (university, corporate, community, and government) accelerate research translation into best practices and policy across the USA and beyond. This article outlines military and veteran health research translation as summarized from a collaborative workshop led by experts across health care research, practice, and administration in DoD, VA, the National Institutes of Health, and affiliated universities. Key themes and recommendations for research translation are outlined in areas of: (a) stakeholder engagement and collaboration; (b) implementation science methods; and (c) funding along the translation continuum. Overall, the ability to rapidly translate research into clinical practice and policy for positive health outcomes requires collaborative relationships among many stakeholders. This includes servicemembers, veterans, and their families along with researchers, health care clinicians, and administrators, as well as policymakers and the broader population.

Consistent with the common-sense model of self-regulation, illness representations are considered the key to improving health outcomes for medically unexplained symptoms and illnesses (MUS)...

Successful fracture fixation depends critically on the stability of the screw-bone interface. Maximum achievable screw torque reflects the competence of this interface, but it cannot be quantified prior to screw stripping. Typically, the surgeon relies on the patients' bone mineral density and radiographs, along with experience and tactile feedback to assess whether sufficient compression can be generated by the screw and bone. However, the local bone quality would also critically influence the strength of the bone-screw interface. We investigated whether Reference Point Indentation can provide quantitative local bone quality measures that can inform subsequent screw-bone competence.We examined the associations between the maximum screw torque that can be achieved using 3.5 mm, 4.5 mm, and 6.5 mm diameter stainless steel screws at the distal femoral metaphysis and mid-diaphysis from 20 cadavers, with the femoral neck bone mineral density and the local measures of bone quality using Reference Point Indentation.Indentation Distance Increase, a measure of bone's resistance to microfracture, correlated with the maximum screw stripping torque for the 3.5 mm (p 0.01; R = 0.56) and 4.5 mm diameter stainless steel screws (p 0.01; R = 0.57) at the femoral diaphysis. At the femoral metaphysis, femoral neck bone mineral density significantly correlated with the maximum screw stripping torque achieved by the 3.5 mm (p 0.01; R = 0.61), 4.5 mm (p 0.01; R = 0.51), and 6.5 mm diameter stainless steel screws (p 0.01; R = 0.56).Reference Point Indentation can provide localized measurements of bone quality that may better inform surgeons of the competence of the bone-implant interface and improve effectiveness of fixation strategies particularly in patients with compromised bone quality.

To evaluate whether objective syndesmosis reduction predicts functional outcomes and pain scores in patients with operatively treated syndesmotic injuries at a minimum 1-year follow-up.Prospective Cohort.Urban Level I Trauma Center.Sixty-nine patients with operatively treated syndesmotic injuries were initially identified and consented for inclusion in the study. Nine patients were excluded perioperatively. Twelve patients were lost to follow-up. Forty-eight patients with operatively treated unilateral syndesmotic injuries were available and participated at the final follow-up.Trans-syndesmotic stabilization with either 1 or 2 quadricortical position screws. Postoperatively, bilateral ankle computed tomography scans were obtained to objectively assess syndesmosis reduction accuracy.Olerud-Molander Ankle Score, Short Musculoskeletal Function Assessment Dysfunction Index and Bother Index, and Numeric Pain Rating Scales at a minimum 1-year postoperative follow-up.At 1-year follow-up, there was no significant difference in functional outcomes between reduced and malreduced groups at the 1.5-, 2-, and 3-mm thresholds for linear measurements. Similarly, there was no functional difference between the reduced and malreduced groups for rotational malreductions at a 10 or 15 degrees threshold. Patients with state-sponsored insurance (Medicaid) had significantly worse functional scores and pain scores when compared with the groups with private insurance, Medicare, or no insurance.At 1-year follow-up, functional outcomes were not related to objective measures of syndesmosis reduction.Prognostic Level II.

People living with medically unexplained symptoms (MUS) often have poor quality of life and health outcomes. Many struggle to engage with and trust in healthcare systems. This qualitative study examined how experiences with institutions influence perceptions of medical care for MUS by applying the theoretical framework of institutional betrayal to narratives of U.S. military Veterans living with Gulf War Illness (GWI). Institutional betrayal refers to situations in which the institutions people depend upon for safety and well-being cause them harm. Experiences of institutional betrayal both during active military service and when first seeking treatment appeared to shape perceptions of healthcare in this sample. Veterans expressed the belief that the military failed to protect them from environmental exposures. Veterans' concerns regarding subsequent quality of healthcare were intrinsically linked to a belief that, despite official documentation to the contrary, the predominant paradigm of both the U.S. Department of Defense and the U.S. Department of Veterans Affairs (VA) is that GWI does not exist. Veterans reported that providers are not adequately trained on treatment of GWI and do not believe Veterans' descriptions of their illness. Veterans reported taking up self-advocacy, doing their own research on their condition, and resigning themselves to decrease engagement with VA healthcare or seek non-VA care. The study's findings suggest institutional level factors have a profound impact on perceptions of care and the patient-provider relationship. Future research and policy aimed at improving healthcare for people living with MUS should consider the concept of institutional betrayal.

To determine whether the position of the medial clamp tine during syndesmotic reduction affected reduction accuracy.Prospective cohort.Urban Level 1 trauma center.Seventy-two patients with operatively treated syndesmotic injuries.Patients underwent operative fixation of their ankle syndesmotic injuries using reduction forceps. The position of the medial clamp tine was then recorded with intraoperative fluoroscopy. Malreduction rates were then assessed with bilateral ankle computerized tomography.Fibular position within the incisura was measured with respect to the uninjured side to determine whether a malreduction had occurred. Malreductions were then analyzed for associations with injury pattern, patient demographics, and the location of the medial clamp tine.A statistically significant association was found between medial clamp position and sagittal plane syndesmosis malreduction. In reference to anterior fibular translation, there was a 0% malreduction rate in the 18 patients where the clamp tine was placed in the anterior third, a 19.4% malreduction rate in the middle third, and 60% malreduction rate in the posterior third (P = 0.006). In reference to posterior fibular translation, there was a 11.1% malreduction when clamp placement was in the anterior third, a 16.1% malreduction rate in the middle third, and 60% malreduction rate in the posterior third (P = 0.062). There were no significant associations between medial clamp position and coronal plane malreductions (overcompression or undercompression) (P = 1).When using reduction forceps for syndesmotic reduction, the position of the medial clamp tine can be highly variable. The angle created with off-axis syndesmotic clamping is likely a major culprit in iatrogenic malreduction. Sagittal plane malreduction appears to be highly sensitive to clamp obliquity, which is directly related to the medial clamp tine placement. Based on these data, we recommend placing the medial clamp tine in the anterior third of the tibial line on the lateral view to minimize malreduction risk.Therapeutic Level IV.

Objectives To compare the timing of soft-tissue (flap) coverage and occurrence of complications before and after the establishment of an integrated orthopaedic trauma/microsurgical team. Design Retrospective cohort study. Setting A single level 1 trauma center. Patients Twenty-eight subjects (13 pre- and 15 post-integration) with open tibia shaft fractures (OTA/AO 42A, 42B, and 42C) treated with flap coverage between January 2009 and March 2015. Intervention Flap coverage for open tibia shaft fractures treated before ("preintegration") and after ("postintegration") implementation of an integrated orthopaedic trauma/microsurgical team. Main outcome measure Time from index injury to flap coverage. Results The unadjusted median time to coverage was 7 days (95% confidence interval, 5.9-8.1) preintegration, and 6 days (95% confidence interval, 4.6-7.4) postintegration (P = 0.48). For preintegration, 9 (69%) of the patients experienced complications, compared with 7 (47%) postintegration (P = 0.23). Conclusions After formation of an integrated orthopaedic trauma/microsurgery team, we observed a 1-day decrease in median days to coverage from index injury. Complications overall were lowered in the postintegration group, although statistically insignificant. Level of evidence Therapeutic Level III.

Social workers play an essential role in facilitating veterans’ reintegration into their communities and daily lives. Many veterans, particularly those who have been deployed, experience comorbid physical, psychological, and neurocognitive problems that significantly impact their health function in multiple domains. Veterans deployed to Operation Desert Shield/Operation Desert Storm have reported a wide range of persistent, diverse, medically unexplained symptoms that have come to be known as Gulf War Illness (GWI). These symptoms make it difficult for veterans to participate in daily activities, thereby impacting health function. There are few effective treatments to improve the health function for those with GWI. The goals of this article are to provide social workers with information about GWI, and describe how we modified an evidence-based treatment, problem-solving therapy, for veterans with GWI. This tailoring of an existing treatment may serve as a model for adapting evidence-based treatments for veterans and civilians with multiple chronic symptoms and other complex health concerns. Furthermore, the detailed description provided may facilitate dissemination of problem-solving therapy among social workers and trainees.

Objective The majority of individuals who endure traumatic events are resilient; however, we do not yet understand why some individuals are more resilient than others. We used data from a prospective longitudinal study Army National Guard and Reserve personnel to examine how unit cohesion (military-specific social support) and avoidant coping relate to resilience over the first year after return from deployment. Method Soldiers (N = 767) were assessed at 4 phases: predeployment (P1), immediately postdeployment (P2), 3 months' postdeployment (P3), and 1-year postdeployment (P4). Results After controlling for predeployment avoidant coping and overall social support, higher unit cohesion was associated with a reduction in avoidant coping (from P1 to P3). This reduction in avoidant coping (from P1 to P3) mediated the relationship between unit cohesion (P2) and improvement in mental health function (from P1 to P3). Conclusions The results are consistent with the hypothesis that higher unit cohesion may mitigate increases in avoidant coping in military personnel after a combat deployment and in turn may improve mental health function.

Patellar tendon ruptures commonly are repaired using transosseous patellar drill tunnels with modified-Krackow sutures in the patellar tendon. This simple suture technique has been associated with failure rates and poor clinical outcomes in a modest proportion of patients. Failure of this repair technique can result from gap formation during loading or a single catastrophic event. Several augmentation techniques have been described to improve the integrity of the repair, but standardized biomechanical evaluation of repair strength among different techniques is lacking.The purpose of this study was to describe a novel figure-of-eight suture technique to augment traditional fixation and evaluate its biomechanical performance. We hypothesized that the augmentation technique would (1) reduce gap formation during cyclic loading and (2) increase the maximum load to failure.Ten pairs (two male, eight female) of fresh-frozen cadaveric knees free of overt disorders or patellar tendon damage were used (average donor age, 76 years; range, 65-87 years). For each pair, one specimen underwent the standard transosseous tunnel suture repair with a modified-Krackow suture technique and the second underwent the standard repair with our experimental augmentation method. Nine pairs were suitable for testing. Each specimen underwent cyclic loading while continuously measuring gap formation across the repair. At the completion of cyclic loading, load to failure testing was performed.A difference in gap formation and mean load to failure was seen in favor of the augmentation technique. At 250 cycles, a 68% increase in gap formation was seen for the control group (control: 5.96 ± 0.86 mm [95% CI, 5.30-6.62 mm]; augmentation: 3.55 ± 0.56 mm [95% CI, 3.12-3.98 mm]; p = 0.02). The mean load to failure was 13% greater in the augmentation group (control: 899.57 ± 96.94 N [95% CI, 825.06-974.09 N]; augmentation: 1030.70 ± 122.41 N [95% CI, 936.61-1124.79 N]; p = 0.01).This biomechanical study showed improved performance of a novel augmentation technique compared with the standard repair, in terms of reduced gap formation during cyclic loading and increased maximum load to failure.Decreased gap formation and higher load to failure may improve healing potential and minimize failure risk. This study shows a potential biomechanical advantage of the augmentation technique, providing support for future clinical investigations comparing this technique with other repair methods that are in common use such as transosseous suture repair.

The opioid crisis has highlighted the importance of improving patients’ access to behavioral treatments for chronic pain and addiction. What is not known is if patients are interested in receiving these treatments. In this cross-sectional study, over 1000 participants with chronic pain were surveyed using an anonymous online questionnaire on Amazon Mechanical Turk (Mturk) to investigate participants’ use of and interest in pharmacological and behavioral treatments for chronic pain and addiction. Participants also indicated whether their doctor had recommended these treatments. The majority of participants reported using medication for their pain (83.19%) and that their doctor recommended medication (85.05%), whereas fewer participants reported using (67.45%) and being recommended to (62.82%) behavioral treatments. We found 63.67% of participants screened positive for possible opioid misuse; those who screened positive were more interested in receiving behavioral treatments than those who did not screen positive. Participants who received treatment recommendations were more likely to be interested in receiving those treatments as compared to participants who did not. The results suggest that recommendations for behavioral treatments and interest in those treatments are related. Results also suggest that patients endorsing behaviors consistent with opioid misuse are interested in behavioral treatments. Perspective: This study provides information around chronic pain patients’ treatment interests, treatment receipt, and recommendation receipt for behavioral pain management and addiction treatment. This study could help facilitate communication between patients and doctors regarding available treatments for chronic pain and pain treatment-related addiction problems.

BACKGROUND: The goal of this randomized clinical trial was to examine the efficacy of a cognitive behavioral stress reduction treatment for reducing disability among veterans with chronic multisymptom illness (CMI). METHOD: Veterans (N=128) who endorsed symptoms of CMI were randomized to: usual care (n=43), in-person (n=42) or telephone-delivered cognitive behavioral stress management (n=43). Assessments were conducted at baseline, three months, and twelve months. The primary outcome was limitation in roles at work and home (i.e., ‘role physical’). Reductions in catastrophizing cognitions were evaluated as a mechanism of action. RESULTS: Intent-to-treat analyses showed no statistically significant main effect (F(2, 164)=.58, p=.56) or interaction effect (F(4,164)=.94, p=.45) for role physical. Over time, veterans improved in their physical function (F(2,170)=5.34, p

Background: The mutual maintenance model proposes that post-traumatic stress disorder (PTSD) symptoms and chronic physical symptoms have a bi-directional temporal relationship. Despite widespread support for this model, there are relatively few empirical tests of the model and these have primarily examined patients with a traumatic physical injury. Objective: To extend the assessment of this model, we examined the temporal relationship between PTSD and physical symptoms for military personnel deployed to combat (i.e., facing the risk of death) who were not evacuated for traumatic injury. Methods: The current study used a prospective, longitudinal design to understand the cross-lagged relationships between PTSD and physical symptoms before, immediately after, 3 months after, and 1 year after combat deployment. Results: The cross-lagged results showed physical symptoms at every time point were consistently related to greater PTSD symptoms at the subsequent time point. PTSD symptoms were related to subsequent physical symptoms, but only at one time-point with immediate post-deployment PTSD symptoms related to physical symptoms at three months after deployment. Conclusion: The findings extend prior work by providing evidence that PTSD and physical symptoms may be mutually maintaining even when there is not a severe traumatic physical injury.

BACKGROUND: Transverse patella fractures are often treated with cannulated screws and a figure-of-eight anterior tension band. A common teaching regarding this construct is to recess the screws so that their distal ends do not protrude beyond the patella because doing so may improve biomechanical performance. However, there is a lack of biomechanical or clinical data to support this recommendation. QUESTION: In the treatment of transverse patella fractures, is there a difference between prominent and recessed cannulated screw constructs, supplemented by tension banding, in terms of gap formation from cyclic loading and ultimate load to failure? METHODS: Ten pairs of fresh-frozen cadaver legs (mean donor age, 72 years; range, 64–89 years) were randomized in a pairwise fashion to prominent or standard-length screws. In the prominent screw group, screw length was 15% longer than the measured trajectory, resulting in 4 to 6 mm of additional length. Each patella was transversely osteotomized at its midportion and fixed with screws and an anterior tension band. Gap formation was measured over 40 loaded flexion-extension cycles (90° to 5°). Ultimate load to failure was assessed with a final monotonic test after cyclic loading. Areal bone mineral density (BMD) of each patella was measured with dual energy x-ray absorptiometry (DEXA). There was no difference in BMD between the recessed (1.06 ± 0.262 g/cm(2)) and prominent (1.03 ± 0.197 g/cm(2)) screw groups (p = 0.846). Difference in gap formation was assessed with a Wilcoxon Rank Sum Test. Ultimate load to failure and BMD were assessed with a paired t-test. RESULTS: Patella fractures fixed with prominent cannulated screws demonstrated larger gap formation during cyclic loading. Median gap size at the end of cyclic loading was 0.13 mm (range, 0.00–2.92 mm) for the recessed screw group and 0.77 mm (range, 0.00–7.50 mm) for the prominent screw group (p = 0.039; 95% confidence interval [CI] difference of geometric means, 0.05–2.12 mm). There was no difference in ultimate failure load between the recessed screw (891 ± 258 N) and prominent screw (928 ± 268 N) groups (p = 0.751; 95% CI difference of means, -226 to 301 N). Ultimate failure load was correlated with areal BMD (r = 0.468; p = 0.046). CONCLUSIONS: In this cadaver study, when using cannulated screws and a figure-of-eight tension band to fix transverse patella fractures, prominent screws reduced the construct’s ability to resist gap formation during cyclic loading testing. CLINICAL RELEVANCE: This biomechanical cadaver study found that the use of prominent cannulated screws for the fixation of transverse patella fractures increases the likelihood of interfragmentary gap formation, which may potentially increase the risk of fracture nonunion and implant failure. These findings suggest that proximally and distally recessed screws may increase construct stability, which may increase the potential for bony healing. The findings support further laboratory and clinical investigations comparing recessed screws supplemented by anterior tension banding with other repair methods that are in common use, such as transosseous suture repair.

To describe the inferior retinacular artery (IRA) as encountered from an anterior approach, to define its intraarticular position, and to define a safe zone for buttress plate fixation of femoral neck fractures.Thirty hips (15 fresh cadavers) were dissected through an anterior (Modified Smith-Petersen) approach after common femoral artery injection (India ink, blue latex). The origin of the IRA from the medial femoral circumflex artery and the course to its terminus were dissected. The IRA position relative to the femoral neck was described using a clock-face system: 12:00 cephalad, 3:00 anterior, 6:00 caudad, and 9:00 posterior.The IRA originated from the medial femoral circumflex artery and traveled within the Weitbrecht ligament in all hips. The IRA positions were 7:00 (n = 13), 7:30 (n = 15), and 8:00 (n = 2). The IRA was 0:30 anterior to (n = 24) or at the same clock-face position (n = 6) as the lesser trochanter. The mean intraarticular length was 20.4 mm (range 11-65, SD 9.1), and the mean extraarticular length was 20.5 mm (range 12-31, SD 5.1).The intraarticular course of the IRA lies within the Weitbrecht ligament between the femoral neck clock-face positions of 7:00 and 8:00. A medial buttress plate positioned at 6:00 along the femoral neck is anterior to the location of the IRA and does not endanger the blood supply of the femoral head. The improved understanding of the IRA course will facilitate preservation during intraarticular approaches to the femoral neck and head.

To evaluate the functional outcomes and pain in patients with unilateral posterior pelvic ring injuries treated with transiliac-transsacral screw fixation compared with unilateral iliosacral screw fixation.Retrospective comparative study.Three academic level 1 trauma centers.From a group of 866 patients with pelvic ring injuries treated surgically, 86 patients with unilateral pelvic ring injuries treated with transiliac-transsacral screws and 97 patients treated with unilateral iliosacral screws were identified. Thirty-six patients treated with transiliac-transsacral fixation and 26 patients treated with unilateral iliosacral screws met the inclusion criteria and participated.Patients were treated surgically for unstable pelvic ring injuries with either unilateral iliosacral screws or transiliac-transsacral screws at the discretion of the treating surgeon.Majeed Pelvic Score.There was no significant difference in Majeed Pelvic Scores between patients treated with transiliac-transsacral screws and those treated with unilateral iliosacral screws (72.8 ± 23.7 vs. 70.4 ± 19.0, P = 0.66). There was no difference in side-specific Numeric Rating Scale pain scores between patients treated with transiliac-transsacral screws and those treated with unilateral iliosacral screws on the injured side (2.5 ± 3.1 vs. 2.0 ± 2.4, P = 0.46) or the uninjured side (1.7 ± 2.8 vs. 0.8 ± 1.7, P = 0.12). Mean follow-up was greater than 3 years with no difference between the groups (mean 1270 vs. 1242 days, P = 0.84).Treatment of unilateral pelvic ring injuries with transiliac-transsacral screws does not adversely affect or improve patient outcomes or subjective pain scores when compared with those treated with unilateral iliosacral screws.Therapeutic Level III.

BACKGROUND: Traumatic Brain Injury (TBI) was deemed the 'signature injury' of the Iraq and Afghanistan Wars (OEF/OIF/OND). Civilians with severe TBI have increased risks of motor vehicle crashes (MVCs). Little is known about MVC risk among Veterans with TBI, many of whom incurred TBIs that were mild in severity. OBJECTIVE: To examine associations between TBI and MVC-related hospitalizations among OEF/OIF/OND Veterans who use Veterans Health Administration (VA) healthcare. METHODS: Using national VA data, we identified 277,330 Veterans who enrolled in VA within one year of deployment. MVC, TBI, and other diagnoses were identified using ICD-9-CM codes. We estimated risk of subsequent MVC hospitalization for those with, versus without, TBI using time-to-event analyses. Time-varying Cox proportional hazards models were used to compute hazard ratios (HR) and 95% confidence intervals (CI) while controlling for potential confounders, including psychiatric diagnoses. RESULTS: There were 28,551 Veterans diagnosed with TBI; 130 were subsequently hospitalized for MVC. In adjusted models, those with TBI were four times more likely to be hospitalized for MVC than those without (HR = 4.2; CI = 3.3-5.3). CONCLUSION: Veterans with TBI had substantially greater risk of MVC-related hospitalizations. These Veterans may benefit from enhanced driving safety interventions to reduce risk. Language: en

The majority of studies to examine the levels of physical symptoms after Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) deployment have found that veterans experience high levels of physical symptoms after deployment. What is not known is whether the physical symptoms experienced by OEF/OIF veterans meet criteria for chronic fatigue syndrome (CFS), as was seen after Operation Desert Shield/Operation Desert Storm. This determination would require a medical evaluation to rule out medical conditions that may explain the symptoms. Further, it is not well known if the physical symptoms experienced by OEF/OIF veterans are causing significant functional impairment. We compared OEF/OIF veterans with CFS to Desert Shield/Storm veterans with CFS seen at a postdeployment Veterans Affairs (VA) clinic soon after their respective deployments. We found 17.6% of OEF/OIF veterans met criteria for CFS. Compared to Desert Shield/Desert Storm veterans with CFS, the OEF/OIF veterans with CFS demonstrated...

Many Veterans returning from service in Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) experience chronic pain. What is not known is whether for some OIF/OEF Veterans this pain is part of a larger condition of diffuse multisystem symptoms consistent with chronic multisymptom illness (CMI). We use data from a prospective longitudinal study of OIF/OEF Veterans to determine the frequency of CMI. We found that 1 yr after deployment, 49.5% of OIF/OEF Veterans met criteria for mild to moderate CMI and 10.8% met criteria for severe CMI. Over 90% of Veterans with chronic pain met criteria for CMI. CMI was not completely accounted for either by posttraumatic stress disorder or by predeployment levels of physical symptoms. Veterans with symptoms consistent with CMI reported significantly worse physical health function than Veterans who did not report symptoms consistent with CMI. This study suggests that the presence of CMI should be considered in the evaluation of OIF/OEF Veterans. Further, it suggests the pain management for these Veterans may need to be tailored to take CMI into consideration.

Objective We examined the magnitude and related costs of potentially avoidable hospitalizations including re-hospitalizations for long-stay residents in nursing homes. Design We conducted our investigation as a retrospective cohort study where the cohort comprised individuals who were eligible for Medicare and had spent at least 120 uninterrupted days in a nursing home in New York State between 2004 and 2007. To conduct the study, we linked the Minimum Data Set, Medicare Provider Assessment File and Provider of Service File. Measurements We defined a potentially avoidable hospitalization as one where a resident was admitted to a hospital for which the principle diagnosis was 1 of 15 ambulatory care sensitive (ACS) conditions. Results Although the percentage of total hospitalizations for ACS conditions declined during the study period, 20% or more of annual hospitalizations were for ACS conditions entailing Medicare payments in excess of $450 million. Approximately 40% of the residents who were hospitalized once for an ACS condition were re-hospitalized during the study period for the same or different ACS condition. Conclusion During the study period, potentially avoidable hospitalizations from nursing homes were a common occurrence in New York. A substantial percentage of such hospitalizations involved residents who had been previously hospitalized, in some cases multiple times, for an ACS condition. Although the observed decline in ACS-related hospitalizations suggests improvements in nursing home care, various policy and managerial-level initiatives may be needed to ensure that nursing home residents are not exposed to a substantial risk of avoidable hospitalizations in the future.

Pipkin described femoral head fractures in the 1950s, but controversy still exists regarding indications for surgery and approaches for operative treatment of femoral head fractures. Clear indications for operative intervention include inability to reduce the hip with closed methods, a nonconcentric reduction, fracture fragments within the articulating surface of the hip, and associated injuries (acetabulum and femoral neck fractures) with their own indications for surgery. The anterior approach described by Smith-Petersen has been modified (using only the distal portion) and used to visualize, clean, reduce, and fix these fractures with and without anterior dislocation of the hip.

Tibial pilon fractures are complex injuries of soft tissue and bone that challenge patients and surgeons. Outcomes following this injury are guarded, and complications are frequently reported. Soft-tissue compromise at the time of injury is potentially amplified with surgical trauma, necessitating thorough evaluation, preoperative planning, and expertise to minimize complications and maximize outcomes. Understanding angiosome anatomy and typical fracture patterns (and their variations) allows for design of surgical tactics that accomplish these goals.

A 2-stage approach to treatment of tibia pilon fractures was reported in the 1990s and popularized over the ensuing decade to help avoid catastrophic soft-tissue complications experienced with one-stage open reduction and internal fixation. This approach can be expanded to the treatment of other high-energy injuries of the hind foot, with variation in external fixator application as needed. Key factors to maximize the utility and decrease complications of the external fixation stage include the following: (1) anatomic reduction of the talus under the long axis of the tibia in the coronal and sagittal planes, (2) strategic application of Schantz pins to resist deforming forces resulting from the injury, and (3) external fixation outside the zone of injury and definitive surgical treatment. This video demonstrates concepts and tactics to obtain and maintain fracture reduction with an external fixator with examples of a complex combined plafond and talus injury, as well as a more typical Orthopaedic Trauma Association/Arbeitsgemeinschaft fur Osteosynthesefragen C-type pilon fracture.

OBJECTIVE: To describe a novel technique using preoperative computed tomography (CT) to plan clamp tine placement along the trans-syndesmotic axis (TSA). We hypothesized that preoperative CT imaging provides a reliable template on which to plan optimal clamp tine positioning along the TSA, reducing malreduction rates compared with other described techniques. METHODS: CT images of 48 cadaveric through-knee specimens were obtained and the TSA was measured as well as the optimal position of the medial clamp tine. The syndesmosis was then fully destabilized. Indirect clamp reductions were performed with the medial clamp tine placed at positions 10° anterior to the TSA, along the TSA, and at both 10° and 20° posterior to the TSA. The specimens were then separately reduced using manual digital pressure and palpation alone. CT was performed after each clamp and manual reduction. RESULTS: On average, reduction clamp tines were within 3±2° of the desired angle and within 5±4% of the templated location along the tibial line for all clamp reduction attempts. Palpation and direct visualization produced the overall lowest malreduction rates in all measurements: 4.9% and 3.0%, respectively. Off-axis clamping 10° anterior or 20° posterior to the patient-specific TSA demonstrated an increased overall malreduction rate: 15.8% and 11.3%, respectively. Significantly more over-compression occurred when a reduction clamp was utilized versus manual digital reduction alone (8.6% vs 0%). CONCLUSIONS: Reduction clamp placement directly along an optimal clamping vector can be facilitated by preoperative CT measurements of the uninjured ankle. However, even in this setting, the use of reduction clamps increases the risk for syndesmotic malreduction and over-compression compared with manual digital reduction or direct visualization.

Background Communication between patients and providers about persistent “medically unexplained” physical symptoms (MUS) is characterized by discordance. While the difficulties are well documented, few studies have examined effective communication. We sought to determine what veterans with Gulf War Illness (GWI) perceive as the most helpful communication from their providers. Veterans with GWI, a type of MUS, have historically had complex relationships with medical providers. Determining effective communication for patients with particularly complex relationships may help identify the most critical communication elements for all patients with MUS. Methods Two hundred and-ten veterans with GWI were asked, in a written questionnaire, what was the most useful thing a medical provider had told them about their GWI. Responses were coded into three categories with 10 codes. Results The most prevalent helpful communication reported by patients was when the provider offered acknowledgement and validation (N = 70). Specific recommendations for managing GWI or its symptoms (N = 48) were also commonly reported to be helpful. In contrast, about a third of the responses indicated that nothing about the communication was helpful (N = 63). There were not differences in severity of symptoms, disability or healthcare utilization between patients who found acknowledgement and validation, specific recommendations or nothing helpful. Conclusions Previous research has documented the discord between patients and providers regarding MUS. This study suggests that most patients are able to identify something helpful a provider has said, particularly acknowledgement and validation and specific treatment recommendations. The findings also highlight missed communication opportunities with a third of patients not finding anything helpful.

BACKGROUND: The Patient Reported Outcomes Measurement Information System (PROMIS) was developed to provide valid, reliable, and standardized measures to gather patient-reported outcomes for many health domains, including depression, independent of patient condition. Most studies confirming the performance of these measures were conducted with a consented, volunteer study population for testing. Using a study population that has undergone the process of informed consent may be differentiated from the validation group because they are educated specifically as to the purpose of the questions and they will not have answers recorded in their permanent health record. QUESTIONS/PURPOSES: (1) When given as part of routine practice to an orthopaedic population, do PROMIS Physical Function and Depression item banks produce score distributions different than those produced by the populations used to calibrate and validate the item banks? (2) Does the presence of a nonnormal distribution in the PROMIS Depression scores in a clinical population reflect a deliberately hasty answering of questions by patients? (3) Are patients who are reporting minimal depressive symptoms by scoring the minimum score on the PROMIS Depression Computer Adaptive Testing (CAT) distinct from other patients according to demographic data or their scores on other PROMIS assessments? METHODS: Univariate descriptive statistics and graphic histograms were used to describe the frequency distribution of scores for the Physical Function and Depression item banks for all orthopaedic patients 18 years or older who had an outpatient visit between June 2015 and December 2016. The study population was then broken into two groups based on whether they indicated a lack of depressive symptoms and scored the minimum score (34.2) on the Depression CAT assessment (Floor Group) or not (Standard Group). The distribution of Physical Function CAT scores was compared between the two groups. Finally, a time-per-question value was calculated for both the Physical Function and Depression CATs and was compared between assessments within each group as well as between the two groups. Bivariate statistics compared the demographic data between the two groups. RESULTS: Physical Function CAT scores in musculoskeletal patients were normally distributed like the distribution calibration population; however, the score distribution of the Depression CAT in musculoskeletal patients was nonnormal with a spike in the floor score. After excluding the floor spike, the distribution of the Depression CAT scores was not different from the population control group. Patients who scored the floor score on the Depression CAT took slightly less time per question for Physical Function CAT when compared with other musculoskeletal patients (floor patients: 11 ± 9 seconds; normally distributed patients: 12 ± 10 seconds; mean difference: 1 second [0.8-1.1]; p < 0.001 but not clinically relevant). They spent a substantially shorter amount of time per question on the Depression CAT (Floor Group: 4 ± 3 seconds; Standard Group: 7 ± 7 seconds; mean difference: 3 [2.9-3.2]; p < 0.001). Patients who scored the minimum score on the PROMIS Depression CAT were younger than other patients (Floor Group: 50 ± 18 SD; Standard Group: 55 ± 16 SD; mean difference: 4.5 [4.2-4.7]; p < 0.001) with a larger percentage of men (Floor Group: 48.8%; Standard Group 40.0%; odds ratio 0.6 [0.6–0.7]; p < 0.001) and minor differences in racial breakdown (Floor Group: white 85.2%, black 11.9%, other 0.03%; Standard Group: white 83.9%, black 13.7%, other 0.02%). CONCLUSIONS: In an orthopaedic surgery population that is given PROMIS CAT as part of routine practice, the Physical Function item bank had a normal performance, but there is a group of patients who hastily complete Depression questions producing a strong floor effect and calling into question the validity of those floor scores that indicate minimal depression. LEVEL OF EVIDENCE: Level II, diagnostic study.

Patients with chronic physical symptoms (e.g., chronic pain) often have significant functional impairment (i.e., disability). The fear avoidance model is the dominant theoretical model of how the relationship between chronic physical symptoms and functional impairment develops and proposes a cyclical/bidirectional relationship. There has never been a definitive test of the proposed bi-directional relationship. The current study followed 767 Operation Enduring Freedom/Operation Iraqi Freedom soldiers from pre-deployment, when they were relatively healthy, to 1 year after deployment, when it was anticipated that symptoms would increase or develop. Over the four assessment time points, physical symptom severity consistently predicted worse functional impairment at the subsequent time point. Functional impairment did not show a consistent relationship with worsening of physical symptom severity. These findings suggest that changes to functional impairment do not have a short-term impact on physical symptom severity.
