ABSTRACT
BACKGROUND: Studies evaluating surgical-site infection have had conflicting results with respect to the use of alcohol solutions containing iodine povacrylex or chlorhexidine gluconate as skin antisepsis before surgery to repair a fractured limb (i.e., an extremity fracture). METHODS: In a cluster-randomized, crossover trial at 25 hospitals in the United States and Canada, we randomly assigned hospitals to use a solution of 0.7% iodine povacrylex in 74% isopropyl alcohol (iodine group) or 2% chlorhexidine gluconate in 70% isopropyl alcohol (chlorhexidine group) as preoperative antisepsis for surgical procedures to repair extremity fractures. Every 2 months, the hospitals alternated interventions. Separate populations of patients with either open or closed fractures were enrolled and included in the analysis. The primary outcome was surgical-site infection, which included superficial incisional infection within 30 days or deep incisional or organ-space infection within 90 days. The secondary outcome was unplanned reoperation for fracture-healing complications. RESULTS: A total of 6785 patients with a closed fracture and 1700 patients with an open fracture were included in the trial. In the closed-fracture population, surgical-site infection occurred in 77 patients (2.4%) in the iodine group and in 108 patients (3.3%) in the chlorhexidine group (odds ratio, 0.74; 95% confidence interval [CI], 0.55 to 1.00; P = 0.049). In the open-fracture population, surgical-site infection occurred in 54 patients (6.5%) in the iodine group and in 60 patients (7.3%) in the chlorhexidine group (odd ratio, 0.86; 95% CI, 0.58 to 1.27; P = 0.45). The frequencies of unplanned reoperation, 1-year outcomes, and serious adverse events were similar in the two groups. CONCLUSIONS: Among patients with closed extremity fractures, skin antisepsis with iodine povacrylex in alcohol resulted in fewer surgical-site infections than antisepsis with chlorhexidine gluconate in alcohol. In patients with open fractures, the results were similar in the two groups.

This study aimed to describe hospital resource utilization of an orthopaedic trauma service and the injury epidemiology during the 2019-2020 coronavirus pandemic to help plan future non-trauma crises. A retrospective chart review was performed on adult patients > 18 years of age who presented to our Level I Trauma Center for musculoskeletal trauma from March 30, 2020 to May 8, 2020 (stay-at-home order) and from March 30, 2019 to May 8, 2019 (comparison group). There were 182 patient encounters and 274 fractures in the 2020 stay-at-home period, and there were 210 patient encounters and 337 fractures in the 2019 control group. There was no statistical difference found comparing the proportion of patient encounters in the stay-at-home period to the control period (p > 0.05). The similar volume of consultations and surgeries justifies maintenance of standard resource allocation. (Journal of Surgical Orthopaedic Advances 32(2):102-106, 2023).

This study assessed the effect of preoperative planning using a 3D-printed periarticular fracture model on operative performance. A complex pilon fracture was 3D-printed, and a preoperative plan was developed. Orthopaedic surgery residents (n = 20) were randomized into two groups. Group 1 performed routine preoperative planning, while Group 2 was also practiced using a 3D-printed construct before performing fixation of the 3D-printed model. Resident performance was assessed using a video motion capture system and evaluated by blinded reviewers. Three residents (3D group) completed fixation within the allotted 45 minutes. The 3D group had less hand distance traveled for step 1 (89 m vs. 162 m, p = 0.04). The 3D group had better performance on three of the four components and more acceptable reductions (6 vs. 0, p = 0.009). Average global rating scale was higher in the 3D group (3.0 vs. 1.7, p = 0.0095). Use of 3D-printed models for preoperative planning improved resident performance.

Opioids are frequently used for acute pain management of musculoskeletal injuries, which can lead to misuse and abuse. This study aimed to identify the opioid prescribing rate for ankle fractures treated nonoperatively in the ambulatory and emergency department setting across a single healthcare system and to identify patients considered at high risk for abuse, misuse, or diversion of prescription opioids that received an opioid. A retrospective cohort study was performed at a large healthcare system. The case list included nonoperatively treated emergency department, urgent care and outpatient clinic visits for ankle fracture and was merged with the Prescription Reporting With Immediate Medication Mapping (PRIMUM) database to identify encounters with prescription for opioids. Descriptive statistics characterize patient demographics, treatment location and prescriber type. Rates of prescribing among subgroups were calculated. There were 1,324 patient encounters identified, of which, 630 (47.6%) received a prescription opioid. The majority of patients were 18-64 years old (60.3%). Patients within this age range were more likely to receive an opioid prescription compared to other age groups (p < .0001). Patients treated in the emergency department were significantly more likely to receive an opioid medication (68.3%) compared to patients treated at urgent care (33.7%) or in the ambulatory setting (16.4%) (p < .0001). Utilizing the PRIMUM tool, 14.2% of prescriptions were provided to patients with at least one risk factor. Despite the recent emphasis on opioid stewardship, 14.2% of patients with risk factors for misuse, abuse, or diversion received opioid analgesics in this study, identifying an area of improvement for prescribers.

Introduction: The aging population reintroduces the need to establish early identification of falls risk as a means of primary and secondary prevention of falls. While there are several existing tools to assess environmental risk factors developed for consumers or home health providers, assessment of environmental falls risk by emergency medical services (EMS) providers represents a novel approach to primary and secondary prevention. The purpose of this study was to evaluate a content valid and reliable assessment of environmental fall risk to be performed in the prehospital setting. Methods: This was a mixed methods study, conducted from August, 2015 to September, 2017 in Mecklenburg County, NC, utilizing qualitative methodology to develop content valid items for an environmental falls risk assessment and quantitative methodology to assess those items for interrater reliability. Content validity was assessed using 2 expert panels. Expert Panel One was tasked with assessing validity of a construct to indicate an increased risk of an in-home fall for elderly individuals and expert Panel Two was responsible for assessing the likelihood of an EMS professional to identify a construct during their course of patient care. To assess reliability of the identified content valid items, 5 paramedics were recruited for interrater reliability (IRR) testing of the validated falls risk assessment tool. Each paramedic and their partner received education on documentation and deployment of the tool. Crews independently documented presence or absence of each item with pair agreement assessed using Cohen's kappa (κ). Results: A total of 87 items were identified for assessment through review of validated scales and relevant literature, with the content validation process reducing to 9 the number of items tested in the field for reliability. A total of 57 paired assessments were completed and included in analysis. One item returned almost perfect agreement (κ = 0.87), 5 items returned moderate agreement (κ = 0.41-0.54), with the remaining 3 items illustrating fair agreement (κ = 0.33-0.39). Conclusion: We developed a construct valid and reliable assessment of environmental falls risk to be performed in the prehospital setting. Further trials should be conducted using this tool to determine appropriate cut scores and deployment in the prehospital setting to help with primary and secondary fall prevention.

US physicians prescribe opioids at a high rate relative to other countries. Of the US physicians surveyed, almost half report having prescribed an inappropriate opioid due to concerns about patient satisfaction scores. We investigated patterns in controlled substance prescribing practices, patient risk factors, and associated Press Ganey patient satisfaction scores at a sample of orthopaedic surgery and primary care clinics over a 6month time period. Primary care practices had higher proportions of prescriptions, and patient risk profiles varied across sites. However, overall satisfaction was high, with little variation between sites (78.3 81.3%). Satisfaction with pain control was lower and more varied (67.1 78.0%). A total of 4,229 Press Ganey survey responses were received, including 7,232 comments, of which only 10 (0.1%) expressed frustration for not receiving opioids. Opioid prescriptions had minimal association with Press Ganey scores among varied practices and patient populations. Prescribers should prescribe opioids appropriately without fear that this will negatively impact their satisfaction scores. (Journal of Surgical Orthopaedic Advances 29(1):59, 2020).

OBJECTIVE: Early antibiotic administration has been associated with a significant decrease in infection following open fractures. However, antibiotics are most effective at a time when many patients are still being transported for care. There is limited evidence that antibiotics may be safely administered for open fractures when being transported by life-flight personnel. No such data exists for ground ambulance transport of patients with open fractures. The purpose of the study was to assess the safety and feasibility of prophylactic antibiotic delivery in the prehospital setting. METHODS: We performed a prospective observational study between January 1, 2014 and May 31, 2015 of all trauma patients transferred to a level 1 trauma center by a single affiliated ground ambulance transport service. If open fracture was suspected, the patient was indicated for antibiotic prophylaxis with 2 g IV Cefazolin. Exclusion criteria included penicillin allergy, higher priority patient care tasks, and remaining transport time insufficient for administration of antibiotics. The administration of antibiotics was recorded. Patient demographics, associated injuries, priority level (1 = life threatening injury, 2 = potentially life threatening injury, 3 = non-life threatening injury), and timing of transport and antibiotic administration were recorded as well. RESULTS: EMTs identified 70 patients during the study period with suspected open fractures. Eight reported penicillin allergy and were not eligible for prophylaxis. The patient's clinical status and transport time allowed for administration of antibiotic prophylaxis for 32 patients (51.6%). Total prehospital time was the only variable assessed that had a significant impact on administration of prehospital antibiotics (<30 minutes = 29% vs. >30 minutes = 66%; p < 0.001). There were no allergic reactions among patients and no needle sticks or other injuries to EMT personnel related to antibiotic administration. CONCLUSIONS: EMT personnel were able to administer prehospital antibiotic prophylaxis for a substantial portion of the identified patients without any complications for patients or providers. Given the limited training provided to EMTs prior to implementation of the antibiotic prophylaxis protocol, it is likely that further development of this initial training will lead to even higher rates of prehospital antibiotic administration for open fractures.

BACKGROUND: Following evidence questioning the safety and efficacy of perioperative beta-blocker therapy in noncardiac surgery, the Surgical Care Improvement Project (SCIP) guidelines were retired in 2015. However, perioperative myocardial infarctions and cardiac complications remain leading causes of mortality following noncardiac surgery. The impact of the SCIP guidelines on reducing cardiac complications in patients undergoing elective total hip arthroplasty (THA) has not been evaluated. METHODS: The Nationwide Inpatient Sample was queried for 345,875 elective THA performed from 2003 to 2011. Patient demographics and morbidity as well as the incidence of nonfatal and fatal cardiac complications and overall mortality associated with cardiac complications were determined before and following SCIP implementation. RESULTS: Following the institution of the SCIP guidelines, the overall mortality following cardiac complications decreased by 41%. Although the incidence of nonfatal cardiac events after THA did increase 5% (primarily secondary to an increased incidence of nonfatal hypotension), the incidence of postoperative inpatient mortality, stroke, fatal hypotension, fatal myocardial infarction, and nonfatal and fatal cardiac arrest significantly decreased. CONCLUSION: Following the implementation of SCIP guidelines, there was a 41% reduction in mortality and a significant decrease in fatal cardiac complications, postoperative hypotension, myocardial infarction, and cardiac arrest. Despite SCIP guidelines being retired in 2015, evidence supports continuation of perioperative beta-blockade in primary elective total adult hip and knee arthroplasty.

BACKGROUND: Treatment options for periprosthetic distal femur fractures include open reduction internal fixation (ORIF) and distal femoral replacement (DFR). The purpose of this study was to evaluate the complications, and functional recovery (ambulatory status, living situation, mortality) in patients undergoing operative treatment (DFR and ORIF) of periprosthetic distal femur fractures. METHODS: A retrospective review of 58 patients with distal femoral periprosthetic fractures treated with either ORIF or DFR was conducted. Surgical complications, discharge disposition, ambulatory status, living situation at 1 year, and mortality at 1 year were compared between patients treated with ORIF and DFR. Outcomes at 1 year were also compared between patients older and younger than 85 years of age. RESULTS: Fifty-eight patients with a mean age of 80 years (range, 61-95 years) met inclusion criteria. The mean follow-up was 29.5 months (range, 5-81 months). Patients undergoing DFR were significantly older than those who underwent ORIF (83 vs 78, P < .01). The 1-year mortality rate was 20.6%. There was no difference between groups with respect to mortality, complications, discharge disposition, or ambulatory status and living situation at 1 year. Patients who lost the ability to ambulate at 1 year were significantly older than patients who maintained the ability to ambulate (87.5 vs 76.4 years, P < .05). Patients older than 85 years were more likely to lose the ability to ambulate and to live in a skilled nursing facility at 1 year (P < .01). CONCLUSION: Distal femoral periprosthetic fractures have a high morbidity and mortality. Age at time of injury, not treatment rendered, is predictive of ambulatory status and living independence after periprosthetic distal femur fractures.

BACKGROUND: The ideal management of distal femur fractures in the elderly is unclear. Acute arthroplasty has the theoretical advantage of earlier mobilization. We examined the outcomes of patients 70 years and older who underwent open reduction internal fixation (ORIF) vs distal femoral replacement (DFR) for comminuted, intra-articular distal femur fractures. METHODS: A retrospective review of patients with AO/OTA classification 33C distal femur fractures treated with either ORIF or DFR was performed. Outcomes including all-cause reoperation, length of stay, fracture union, postoperative complications, use of ambulatory device and living situation at 1 year, and mortality were evaluated. RESULTS: The study cohort included 38 patients: 10 underwent DFR and 28 ORIF. Mean patient age for both cohorts was 82 years. No difference in comorbidities or mechanism of injury was found between groups. The incidence of reoperation was 11% in the ORIF group and 10% in the DFR group. In the ORIF group, the average time to fracture union was 24 weeks, with a nonunion incidence of 18%. Twenty-three percent of ORIF group were wheelchair dependent vs none in the DFR cohort, although not statistically significant. Differences between the groups with respect to all-cause reoperation, living situation or need for ambulatory device at 1 year, and 1-year mortality did not reach statistical significance. CONCLUSION: Nearly 1 in 5 patients older than 70 years developed a nonunion after ORIF of an intra-articular distal femur fracture. At 1-year follow-up, all patients in DFR group were ambulatory while 1 in 4 in the ORIF group were wheelchair bound.

BACKGROUND: Perioperative myocardial infarctions and cardiac complications are leading causes of mortality after noncardiac surgery. In an effort to improve patient safety, the Surgical Care Improvement Project (SCIP) implemented guidelines concerning administration of ß-blockers therapy aimed to reduce cardiac complications. METHODS: The Nationwide Inpatient Sample was queried for 759,819 elective total knee arthroplasties performed from 2003 to 2011. Incidence of cardiac complications, mortality, and risk factors for cardiac complications was determined before and after SCIP implementation. RESULTS: The incidence of cardiac events after total knee arthroplasty remained stable at 9%. The incidence and mortality of postoperative stroke, myocardial infarction, and cardiac arrest significantly decreased. Mortality after cardiac complications decreased by 50%. CONCLUSION: After the implementation of SCIP guidelines, there was a greater than 50% reduction in mortality and a significant decrease in fatal postoperative stroke, heart failure, and cardiac arrest.

This study aimed to explore the potential of gait analysis coupled with supervised machine learning models as a predictive tool for assessing post-injury complications such as infection, malunion, or hardware irritation among individuals with lower extremity fractures. We prospectively identified participants with lower extremity fractures at a tertiary academic center. These participants underwent gait analysis with a chest-mounted inertial measurement unit device. Using customized software, the raw gait data were preprocessed, emphasizing 12 essential gait variables. The data were standardized, and several machine learning models, including XGBoost, logistic regression, support vector machine, LightGBM, and Random Forest, were trained, tested, and evaluated. Special attention was given to class imbalance, addressed using the synthetic minority oversampling technique (SMOTE). Additionally, we introduced a novel methodology to compute the post-injury recovery rate for gait variables, which operates independently of the time difference between the gait analyses of different participants. XGBoost was identified as the optimal model both before and after the application of SMOTE. Before using SMOTE, the model achieved an average test area under the ROC curve (AUC) of 0.90, with a 95% confidence interval (CI) of [0.79, 1.00], and an average test accuracy of 86%, with a 95% CI of [75%, 97%]. Through feature importance analysis, a pivotal role was attributed to the duration between the occurrence of the injury and the initial gait analysis. Data patterns over time revealed early aggressive physiological compensations, followed by stabilization phases, underscoring the importance of prompt gait analysis. χ2 analysis indicated a statistically significant higher readmission rate among participants with underlying medical conditions (p = 0.04). Although the complication rate was also higher in this group, the association did not reach statistical significance (p = 0.06), suggesting a more pronounced impact of medical conditions on readmission rates rather than on complications. This study highlights the transformative potential of integrating advanced machine learning techniques like XGBoost with gait analysis for orthopedic care. The findings underscore a shift toward a data-informed, proactive approach in orthopedics, enhancing patient outcomes through early detection and intervention. The χ2 analysis added crucial insights into the broader clinical implications, advocating for a comprehensive treatment strategy that accounts for the patient's overall health profile. The research paves the way for personalized, predictive medical care in orthopedics, emphasizing the importance of timely and tailored patient assessments.

OBJECTIVES: Evaluate the effect of anterior fixation on infection in patients with operative pelvic fractures and bladder or urethral injuries. DESIGN: Retrospective. SETTING: Eight centers. PATIENT SELECTION CRITERIA: Adult patients with closed pelvic fractures with associated bladder or urethral injuries treated with anterior plating (AP), intramedullary screw (IS), or no anterior internal fixation (NAIF, including external fixation or no fixation). OUTCOME MEASURES AND COMPARISONS: Deep infection. RESULTS: There were 81 extraperitoneal injuries and 57 urethral injuries. There was no difference in infection between fixation groups across all urologic injuries (AP: 10.8%, IS: 0%, NAIF: 4.9%, P = 0.41). There was a higher rate of infection in the urethral injury group compared with extraperitoneal injuries (14.0% vs. 2.5%, P = 0.016). Among extraperitoneal injuries, specifically, there was no difference in deep infection related to fixation (AP: 2.6%, IS 0%, NAIF: 2.9%, P = 0.99). Among urethral injuries, there was no statistical difference in deep infection related to fixation (AP: 23.1%, IS: 0%, NAIF: 7.4%, P = 0.21). There was a higher rate of suprapubic catheter (SPC) use in urethral injuries compared with extraperitoneal injuries (57.9% vs. 4.9%, P < 0.0001). In the urethral injury group, SPC use did not have a statistically significant difference in infection rate (SPC: 18.2% vs. No SPC: 8.3%, P = 0.45). Early removal of the SPC before or during the definitive orthopaedic intervention did not significantly affect infection rate (early: 0% vs. delayed: 25.0%, P = 0.16). CONCLUSIONS: Surgeons should approach operative pelvic fractures with associated urologic injuries with caution given the high risk of infection. Further work must be done to elucidate the effect of anterior implants and SPC use and duration. LEVEL OF EVIDENCE: Prognostic Level III.

OBJECTIVES: To evaluate the work relative value units (RVUs) attributed per minute of operative time (wRVU/min) in fixation of acetabular fractures, evaluate surgical factors that influence wRVU/min, and compare wRVU/min with other procedures. DESIGN: Retrospective. SETTING: Level 1 academic center. PATIENT SELECTION CRITERIA: Two hundred fifty-one operative acetabular fractures (62 A, B, C) from 2015 to 2021. OUTCOME MEASURES AND COMPARISONS: Work relative value unit per minute of operative time for each acetabular current procedural terminology (CPT) code. Surgical approach, patient positioning, total room time, and surgeon experience were collected. Comparison wRVU/min were collected from the literature. RESULTS: The mean wRVU per surgical minute for each CPT code was (1) CPT 27226 (isolated wall fracture): 0.091 wRVU/min, (2) CPT 27227 (isolated column or transverse fracture): 0.120 wRVU/min, and (3) CPT 27228 (associated fracture types): 0.120 wRVU/min. Of fractures with single approaches, anterior approaches generated the least wRVU/min (0.091 wRVU/min, P = 0.0001). Average nonsurgical room time was 82.1 minutes. Surgeon experience ranged from 3 to 26 years with operative time decreasing as surgeon experience increased ( P = 0.03). As a comparison, the wRVU/min for primary and revision hip arthroplasty have been reported as 0.26 and 0.249 wRVU/min, respectively. CONCLUSIONS: The wRVUs allocated per minute of operative time for acetabular fractures is less than half of other reported hip procedures and lowest for isolated wall fractures. There was a significant amount of nonsurgical room time that should be accounted for in compensation models. This information should be used to ensure that orthopaedic trauma surgeons are being appropriately supported for managing these fractures. LEVEL OF EVIDENCE: Economic Level IV.

BACKGROUND: The purpose of this study was to compare 18-month clinical and patient-reported outcomes between patients with severe lower-limb injuries treated with a transtibial amputation or a hind- or midfoot amputation. Despite the theoretical benefits of hind- and midfoot-level amputation, we hypothesized that patients with transtibial amputations would report better function and have fewer complications. METHODS: The study included patients 18 to 60 years of age who were treated with a transtibial amputation (n = 77) or a distal amputation (n = 17) and who were enrolled in the prospective, multicenter Outcomes Following Severe Distal Tibial, Ankle, and/or Foot Trauma (OUTLET) study. The primary outcome was the difference in Short Musculoskeletal Function Assessment (SMFA) scores, and secondary outcomes included pain, complications, amputation revision, and amputation healing. RESULTS: There were no significant differences between patients with distal versus transtibial amputation in any of the domains of the SMFA: dysfunction index [distal versus transtibial], 31.2 versus 22.3 (p = 0.13); daily activities, 37.3 versus 26.0 (p = 0.17); emotional status, 41.4 versus 29.3 (p = 0.07); mobility, 36.5 versus 27.8 (p = 0.20); and bother index, 34.4 versus 23.6 (p = 0.14). Rates of complications requiring revision were higher for distal amputations but not significantly so (23.5% versus 13.3%; p = 0.28). One distal and no transtibial amputees required revision to a higher level (p = 0.18). A higher proportion of patients with distal compared with transtibial amputation required local surgical revision (17.7% versus 13.3%; p = 0.69). There was no significant difference between the distal and transtibial groups in scores on the Brief Pain Index at 18 months post-injury. CONCLUSIONS: Surgical complication rates did not differ significantly between patients who underwent transtibial versus hind- or midfoot amputation for severe lower-extremity injury. The average SMFA scores were higher (worse), although not significantly different, for patients undergoing distal compared with transtibial amputation, and more patients with distal amputation had a complication requiring surgical revision. Of note, more patients with distal amputation required closure with an atypical flap, which likely contributed to less favorable outcomes. LEVEL OF EVIDENCE: Therapeutic Level III .

BACKGROUND: Current guidelines recommend low-molecular-weight heparin for thromboprophylaxis after orthopaedic trauma. However, recent evidence suggests that aspirin is similar in efficacy and safety. To understand patients' experiences with these medications, we compared patients' satisfaction and out-of-pocket costs after thromboprophylaxis with aspirin versus low-molecular-weight heparin. METHODS: This study was a secondary analysis of the PREVENTion of CLots in Orthopaedic Trauma (PREVENT CLOT) trial, conducted at 21 trauma centers in the U.S. and Canada. We included adult patients with an operatively treated extremity fracture or a pelvic or acetabular fracture. Patients were randomly assigned to receive 30 mg of low-molecular-weight heparin (enoxaparin) twice daily or 81 mg of aspirin twice daily for thromboprophylaxis. The duration of the thromboprophylaxis, including post-discharge prescription, was based on hospital protocols. The study outcomes included patient satisfaction with and out-of-pocket costs for their thromboprophylactic medication measured on ordinal scales. RESULTS: The trial enrolled 12,211 patients (mean age and standard deviation [SD], 45 ± 18 years; 62% male), 9725 of whom completed the question regarding their satisfaction with the medication and 6723 of whom reported their out-of-pocket costs. The odds of greater satisfaction were 2.6 times higher for patients assigned to aspirin than those assigned to low-molecular-weight heparin (odds ratio [OR]: 2.59; 95% confidence interval [CI]: 2.39 to 2.80; p < 0.001). Overall, the odds of incurring any out-of-pocket costs for thromboprophylaxis medication were 51% higher for patients assigned to aspirin compared with low-molecular-weight heparin (OR: 1.51; 95% CI: 1.37 to 1.66; p < 0.001). However, patients assigned to aspirin had substantially lower odds of out-of-pocket costs of at least $25 (OR: 0.15; 95% CI: 0.12 to 0.18; p < 0.001). CONCLUSIONS: Use of aspirin substantially improved patients' satisfaction with their medication after orthopaedic trauma. While aspirin use increased the odds of incurring any out-of-pocket costs, it protected against costs of ≥$25, potentially improving health equity for thromboprophylaxis.

BACKGROUND: We previously found no reduction in heterotopic ossification (HO) rates after acetabular surgery with indomethacin compared with a placebo. We subsequently abandoned routine indomethacin therapy after acetabular surgery but questioned whether the incidence had changed using a posterior approach. QUESTIONS/PURPOSES: We therefore determined (1) the incidence of HO after acetabular fracture surgery through a posterior approach; (2) the incidence of symptoms attributable to HO; and (3) the rate of reoperation for HO. METHODS: We retrospectively reviewed the records of all 423 patients with acetabular fractures following our clinical protocol change; of these, 120 were treated with a Kocher-Langenbeck approach and included. The presence of radiographic HO was documented a minimum of 10 weeks postoperatively using the classification of Brooker et al. Symptoms and reoperations were recorded. RESULTS: The overall incidence of radiographic HO was 47% (56 of 120 patients): 26% Class I-II 13% Class III, and 8% Class IV. Overall, 15% of patients developed symptoms; 3.3% underwent reoperations for excision of HO. There were no major differences between the incidence of moderate and severe HO in this study when compared with the indomethacin and placebo groups from the prior study. CONCLUSIONS: Our incidence of moderate and severe HO has not changed since discontinuing indomethacin. These findings support our institutional decision to abandon routine indomethacin prophylaxis after acetabular surgery. We recommend improved surgical techniques to limit damage to the abductors and improved risk stratification of patients when considering treatment options for HO prophylaxis.

OBJECTIVES: To characterize the recruitment rates at a Level I trauma center enroling for multiple prospective orthopaedic trauma research studies and identify patient-related and study-related predictors of consent. DESIGN: We conducted a case-control study to identify predictors of study consent. The authors categorized studies based on intensity of the study intervention (low, intermediate, or high). A 2-level generalized linear model with random intercept for study was used to predict study consent. SETTING: This analysis includes data from 10 federally funded studies conducted as part of a large, national consortium that were enroling patients in 2013-2014. PATIENTS/PARTICIPANTS: Three hundred thirty-four patients were approached for at least 1 study and included in the analysis. INTERVENTION: N/A. MAIN OUTCOME MEASURES: Consent to participate in the research study. RESULTS: A total of 315 patients consented to be in a study (71% of approached patients). Consent rate varied by study (45%-95%). No patient characteristics (race, age, or sex) were associated with consent. Patients approached for studies of intermediate intensity were 83% less likely to consent (odds ratio = 0.17; 95% confidence interval: 0.04-0.67), and those approached for studies of high intensity were 91% less likely to consent (odds ratio = 0.09; 95% confidence interval: 0.03-0.32). CONCLUSION: Patient factors were not associated with consent. Study intensity is a major driver of consent rates. Studies of higher intensity will require the study team to approach up to twice as many patients as the target enrolment. This study provides a framework that can be used in study planning and determination of feasibility.

OBJECTIVE: The objective is to quantify the rate of opioid and benzodiazepine prescribing for the diagnosis of shoulder osteoarthritis across a large healthcare system and to describe the impact of a clinical decision support intervention on prescribing patterns. DESIGN: A prospective observational study. SETTING: One large healthcare system. PATIENTS AND PARTICIPANTS: Adult patients presenting with shoulder osteoarthritis. INTERVENTIONS: A clinical decision support intervention that presents an alert to prescribers when patients meet criteria for increased risk of opioid use disorder. MAIN OUTCOME MEASURE: The percentage of patients receiving an opioid or benzodiazepine, the percentage who had at least one risk factor for misuse, and the percent of encounters in which the prescribing decision was influenced by the alert were the main outcome measures. RESULTS: A total of 5,380 outpatient encounters with a diagnosis of shoulder osteoarthritis were included. Twenty-nine percent (n = 1,548) of these encounters resulted in an opioid or benzodiazepine prescription. One-third of those who received a prescription had at least one risk factor for prescription misuse. Patients were more likely to receive opioids from the emergency department or urgent care facilities (40 percent of encounters) compared to outpatient facilities (28 percent) (p < .0001). Forty-four percent of the opioid prescriptions were for "potent opioids" (morphine milliequivalent conversion factor > 1). Of the 612 encounters triggering an alert, the prescribing decision was influenced (modified or not prescribed) in 53 encounters (8.7 percent). All but four (0.65 percent) of these encounters resulted in an opioid prescription. CONCLUSION: Despite evidence against routine opioid use for osteoarthritis, one-third of patients with a primary diagnosis of glenohumeral osteoarthritis received an opioid prescription. Of those who received a prescription, over one-third had a risk factor for opioid misuse. An electronic clinic decision support tool influenced the prescription in less than 10 percent of encounters.

OBJECTIVE: Acute compartment syndrome (ACS) is a true emergency. Even with urgent fasciotomy, there is often muscle damage and need for further surgery. Although ACS is not uncommon, no validated classification system exists to aid in efficient and clear communication. The aim of this study was to establish and validate a classification system for the consequences of ACS treated with fasciotomy. METHODS: Using a modified Delphi method, an international panel of ACS experts was assembled to establish a grading scheme for the disease and then validate the classification system. The goal was to articulate discrete grades of ACS related to fasciotomy findings and associated costs. A pilot analysis was used to determine questions that were clear to the respondents. Discussion of this analysis resulted in another round of cases used for 24 other raters. The 24 individuals implemented the classification system 2 separate times to compare outcomes for 32 clinical cases. The accuracy and reproducibility of the classification system were subsequently calculated based on the providers' responses. RESULTS: The Fleiss Kappa of all raters was at 0.711, showing a strong agreement between the 24 raters. Secondary validation was performed for paired 276 raters and correlation was tested using the Kendall coefficient. The median correlation coefficient was 0.855. All 276 pairs had statistically significant correlation. Correlation coefficient between the first and second rating sessions was strong with the median pair scoring at 0.867. All surgeons had statistically significant internal consistency. CONCLUSION: This new ACS classification system may be applied to better understand the impact of ACS on patient outcomes and economic costs for leg ACS.
