RESUMO

PURPOSE: The negative effects of smoking following traumatic orthopaedic injury can lead to serious complications and decreased quality of life. The widely available quitline could be easily implemented in the orthopaedic postoperative period to improve outcome, but the effectiveness of this intervention in this population is unknown. The goal of this study was to determine if active referral to a quitline would improve rates of smoking cessation in this population. METHODS: This is a secondary analysis of a randomized control trial assessing the effectiveness of an inpatient intervention with varying intensities to promote smoking cessation. Participants were actively referred to the quitline as part of their intervention. Participants were surveyed at 6 weeks, 3 months and 6 months following their injury for 7-day abstinence, chemically confirmed with exhaled carbon monoxide monitoring. RESULTS: Smoking quitline use alone does not independently improve 7-day abstinence. Quitline and nicotine use are synergistic (OR, 5.6 vs. 2.3 at 3 months in patients who used nicotine patch and quitline vs. patch; OR, 7.8 vs. 2.1 at 3 months in patients who used any NRT and quitline vs. NRT alone). CONCLUSIONS: NRT use improves smoking cessation rates in orthopaedic trauma patients. Although smoking quitline use might not independently improve cessation rates in orthopaedic trauma patients postoperatively, concomitant use of NRT with quitline improves quit rates over NRT alone. Patients referred to quitline should be encouraged to use NRT.

RESUMO

Displaced intra-articular calcaneus fractures (DIACFs) are difficult injuries to treat and are often encountered by orthopedic surgeons. For DIACFs treated nonoperatively or with open reduction internal fixation (ORIF), a common complication is painful subtalar arthritis and the need for a secondary subtalar fusion, which prolongs the overall recovery time. One treatment option to address this sequela involves ORIF with subtalar fusion as the primary treatment. We describe a reproducible, minimally invasive surgical technique for primary ORIF with subtalar fusion when the calcaneal tuberosity is amendable to cannulated screw fixation to treat these complex calcaneal fractures. Our technique offers advantages compared to other techniques in that it avoids screw traffic, allows easy bony compression of the subtalar joint, and minimizes soft tissue damage via percutaneous screw fixation. Fourteen fractured calcanei in 12 patients underwent our technique and all achieved bony union with a median time to fusion of 107.5 days (range, 54-530 days). Eight patients returned to work with the remaining 4 patients having an unknown work status at last follow-up, although 2 of these 4 patients resumed normal activities. Only 1 patient experienced a complication, which was an infection after achieving bony union, and was treated with successful hardware removal and our infection protocol. Overall, we conclude our surgical technique offers a successful option in the treatment of DIACFs when the calcaneal tuberosity is amendable to cannulated screw fixation.

RESUMO

PURPOSE: It remains unknown if cephalomedullary nail (CMN) length has an impact on pain and opioid use following fixation. Given the lack of level I evidence favoring a specific CMN length to prevent adverse surgical outcomes, we investigated if CMN length impacts acute postoperative pain and opioid use. The authors hypothesize that the use of longer CMNs results in increased pain scores and morphine milligram equivalents (MME) intake during the 0-24 h (h) and 24-36 h postoperative period. METHODS: A retrospective chart review was performed from 2010 to 2020 of patients ≥ 65 years-old who underwent CMN for IT fractures and fractures with subtrochanteric extension (STE). We compared patients who received short and long CMNs using numeric rating scale (NRS) pain scores and MME intake at 0-24 h and 24-36 h postoperatively. RESULTS: 330 patients receiving short (n = 155) and long (n = 175) CMNs met criteria. CMN length was found to not be associated with higher pain scores in the early postoperative phase. However, patients with long CMNs received higher MME from 0-24 h (25.4% estimated mean increase, p value = 0.02) and 24-36 h (22.3% estimated mean increase, p value = 0.04) postoperatively, even after adjusting for covariates, gender, and age. CONCLUSION: Patients with long CMNs received greater MME postoperatively. Additionally, differences in pain and MME were not significantly different between patients with and without STE, suggesting our findings were not influenced by this pattern. These results suggest longer CMNs are associated with higher acute postoperative opioid intake among patients with IT fractures. LEVEL OF EVIDENCE: Therapeutic level III.

RESUMO

We aimed to determine whether addition of an in vivo ectopic induced membrane (EM) to the Masquelet Technique enhanced angiogenesis and bone formation in a segmental defect. After generating and stabilizing a diaphyseal femur defect, 10 rats received a polymethylmethacrylate (PMMA) spacer within the defect (control); 10 received another PMMA spacer implanted subcutaneously (EM). We removed the spacers and added autograft; the excised EM was added to their autograft (EM group). Post-mortem x-rays assessed bone formation and bridging. Osteogenesis in the proximal defect was significantly more uniform (p < 0.01), and there was greater amount of bone remodeling distally in the EM group (p < 0.05). There was no difference in bone formation (p = 0.19) but greater degrees of bridging in the EM group (2.20 vs. 1.20, p = 0.09). The EM resulted in more homogeneous proximal osteogenesis and increased bone remodeling distally. These findings could lead to more consistent and predictable bone healing.

RESUMO

OBJECTIVES: To determine whether a modified version of the STarT Back Screening Tool in its current structure has adequate properties for use in patients with lower extremity fracture. DESIGN: Single-center, prospective study. SETTING: Level I trauma center. PARTICIPANTS: Patients with lower extremity fracture without a history of chronic pain (N=114), with 93% follow-up. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Six weeks after surgical fixation, individuals completed the Subgroups for Targeted Treatment of Lower Extremity Screening Tool (STarT-LE). A subsample completed the STarT-LE again 1 week later. The following questionnaires were completed at 6 weeks and 6 months: Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia, Brief Pain Inventory pain intensity subscale, and PROMIS Depression and Pain Interference computer adaptive testing modules. Reliability was evaluated using intraclass correlation coefficients (ICC) and Cronbach's alpha (α). Convergent validity evidence was measured concurrently using the Spearman ρ correlation between the 6-week STarT-LE and established questionnaires. Predictive validity evidence was evaluated by area under the curve analysis (AUC) using the 6-week STarT-LE total and psychosocial scores and 6-month criterion physical and psychosocial reference standards. RESULTS: The STarT-LE has good test-retest reliability (ICC, 0.85; 95% confidence interval, 0.78-0.91) and acceptable internal consistency (α=0.74). The convergent validity evidence was fair to moderate (ρ, 0.53-0.68; P<.001) and the predictive validity evidence was acceptable to excellent (AUC, 0.73-0.84). CONCLUSIONS: The STarT-LE has adequate properties for use in patients with lower extremity fracture. Future larger scale studies are needed to validate risk cutoffs.

RESUMO

BACKGROUND: Early administration of antibiotics and wound coverage have been shown to decrease the deep infection risk in all patients with Type 3 open tibia fractures. However, it is unknown whether early antibiotic administration decreases infection risk in patients with Types 1, 2, and 3A open tibia fractures treated with primary wound closure. QUESTIONS/PURPOSES: (1) Does decreased time to administration of the first dose of antibiotics decrease the deep infection risk in all open tibia fractures with primary wound closure? (2) What patient demographic factors are associated with an increased deep infection risk in Types 1, 2, and 3A open tibia fractures with primary wound closure? METHODS: We identified 361 open tibia fractures over a 5-year period at a Level I regional trauma center that receives direct admissions and transfers from other hospitals which produces large variation in the timing of antibiotic administration. Patients were excluded if they were younger than 18 years, had associated plafond or plateau fractures, associated with compartment syndrome, had a delay of more than 24 hours from injury to the operating room, underwent repeat débridement procedures, had incomplete data, and were treated with negative-pressure dressings or other adjunct wound management strategies that would preclude primary closure. Primary closure was at the descretion of the treating surgeon. We included patients with a minimum follow-up of 6 weeks with assessment at 6 months and 12 months. One hundred forty-three patients with were included in the analysis. Our primary endpoint was deep infection as defined by the CDC criteria. We obtained chronological data, including the time to the first dose of antibiotics and time to surgical débridement from ambulance run sheets, transferring hospital records, and the electronic medical record to answer our first question. We considered demographics, American Society of Anesthesiologists classification, mechanism of injury, smoking status, presence of diabetes, and Injury Severity Score in our analysis of other factors. These were compared using one-way ANOVA, chi-square, or Fisher's exact tests. Binary regression was used to to ascertain whether any factors were associated with postoperative infection. Receiver operator characteristic curves were used to identify threshold values. RESULTS: Increased time to first administration of antibiotics was associated with an increased infection risk in patients who were treated with primary wound closure; the greatest inflection point on that analysis occurred at 150 minutes, when the increased infection risk was greatest (20% [8 of 41] versus 4% [3 of 86]; odds ratio 5.6 [95% CI 1.4 to 22.2]; p = 0.01). After controlling for potential confounding variables like age, diabetes and smoking status, none of the variables we evaluated were associated with an increased risk of deep infection in Type 1, 2, and 3A open tibia fractures in patients treated with primary wound closure. CONCLUSION: Our findings suggest that in open tibia fractures, which receive timely antibiotic administration, primary wound closure is associated with a decreased infection risk. We recognize that more definitive studies need to be performed to confirm these findings and confirm feasibility of early antibiotic administration, especially in the pre-hospital context. LEVEL OF EVIDENCE: Level III, therapeutic study.

RESUMO

BACKGROUND: There is concern that regional anesthesia is associated with increased risk of complications, including return to the hospital for uncontrolled pain once the regional anesthetic wears off. METHODS: Retrospective database review of patients who underwent open reduction and internal fixation of a closed ankle fracture from 2014-16 who received general anesthesia alone (GA) or general anesthesia plus regional anesthesia (RA). RESULTS: 9459 patients met inclusion criteria. Patients in the RA group had significantly longer operative duration in both inpatient (GAI=71min vs RAI=79min, p=0.002) and outpatient setting (GAO=66min vs RAI=72min, p<0.001), lower overall LOS (GA=1.7 days vs RA=1.1 days, p<0.001), and higher readmission rate for pain (RAO=4 [0.3%] vs GAO=1 [0.0%], p=0.007). CONCLUSIONS: Patients who received supplemental regional anesthesia had shorter hospital LOS, increased operative time, and increased readmission rates for rebound pain. However, the small number of patients needing readmission are not clinically significant demonstrating that regional anesthesia is safe, effective and readmission for rebound pain should not be a concern. LEVEL OF EVIDENCE: III.

RESUMO

OBJECTIVES: Determine adherence to a newly implemented protocol of fascia iliaca compartment block (FICB) in geriatric hip fractures. DESIGN: Retrospective review. SETTING: Level I trauma center. PATIENT SELECTION CRITERIA: Patients with a hip fracture treated with cephalomedullary nailing or hemiarthroplasty (CPT codes 27245 or 27236). OUTCOME MEASURES AND COMPARISONS: Adherence to a protocol for FICB, time intervals between emergency department arrival, FICB, and surgery stratified by time of admission. RESULTS: Three hundred eighty patients were studied (average age 78 years, 70% female). Approximately 53.2% of patients received an FICB, which was less than a predefined acceptable adherence rate of 75% ( P < 0.001). Approximately 5.0% received an FICB within 4 hours and 17.3% within 6 hours from admission. Admission during daylight hours (7 am -7p m ) when compared with evening hours (7 pm -7 am ) was associated with improved timeliness ([8.3% vs. 0% within 4 hours, P < 0.001] [27.5% vs. 2.4% within 6 hours, P < 0.001]). Improved adherence to the protocol was observed over time (odds ratio: 1.0013, 95% confidence interval, 1.0001-1.0025, P = 0.0388). CONCLUSIONS: FICB implementation was poor but gradually improved over time. Few patients received an FICB promptly, especially during night hours. Overall, this study demonstrates that implementation of an FICB program at a Level I academic trauma center can be difficult; however, many hurdles can be overcome with institutional support and dedication of resources such as staff, space, and additional training.

RESUMO

Purpose: To identify factors associated with delays in administration and pharmacy and nursing preparation of antibiotics for patients with open fractures. Design: Retrospective review. Setting: Level I trauma center. Patients: Nine hundred sixty-three adults with open fractures administered antibiotics. Main Outcome Measurements: Delay in antibiotic administration greater than 66 minutes from arrival and significant pharmacy-related and nursing-related delay. Results: Isolated injury, Charlson Comorbidity Index, and transfer from another facility were associated with delay in antibiotic administration greater than 66 minutes. Injury Severity Score, transfer, and trauma team activation were associated with pharmacy-related or nursing-related delay. Conclusion: Interventions to reduce antibiotic administration time for open fractures should focus on early identification of open fractures and standardization of antibiotic protocols to ensure timely administration even in complex or resource-scarce care situations. Level of Evidence: Prognostic level III.

RESUMO

OBJECTIVES: To compare radiographic and clinical outcomes in nonoperative management of humeral shaft fractures treated initially with coaptation splinting (CS) followed by delayed functional bracing (FB) versus treatment with immediate FB. DESIGN: Retrospective cohort study. SETTING: Academic Level 1 Trauma Center. PATIENT SELECTION CRITERIA: Patients with closed humeral shaft fractures managed nonoperatively with initial CS followed by delayed FB or with immediate FB from 2016 to 2022. Patients younger than 18 years and/or with less than 3 months of follow-up were excluded. OUTCOME MEASURES AND COMPARISONS: The primary outcome was coronal and sagittal radiographic alignment assessed at the final follow-up. Secondary outcomes included rate of failure of nonoperative management (defined as surgical conversion and/or fracture nonunion), fracture union, and skin complications secondary to splint/brace wear. RESULTS: Ninety-seven patients were managed nonoperatively with delayed FB (n = 58) or immediate FB (n = 39). Overall, the mean age was 49.9 years (range 18-94 years), and 64 (66%) patients were female. The immediate FB group had less smokers ( P = 0.003) and lower incidence of radial nerve palsy ( P = 0.025), with more proximal third humeral shaft fractures ( P = 0.001). There were no other significant differences in demographic or clinical characteristics ( P > 0.05). There were no significant differences in coronal ( P = 0.144) or sagittal ( P = 0.763) radiographic alignment between the groups. In total, 33 (34.0%) humeral shaft fractures failed nonoperative management, with 11 (28.2%) in the immediate FB group and 22 (37.9%) in the delayed FB group ( P = 0.322). There were no significant differences in fracture union ( P = 0.074) or skin complications ( P = 0.259) between the groups. CONCLUSIONS: This study demonstrated that nonoperative treatment of humeral shaft fractures with immediate functional bracing did not result in significantly different radiographic or clinical outcomes compared to treatment with CS followed by delayed functional bracing. Future prospective studies assessing patient-reported outcomes will further guide clinical decision making. LEVEL OF EVIDENCE: Therapeutic Level III.

RESUMO

The mechanical properties of the human supraspinatus tendon (SST) are highly heterogeneous and may reflect an important adaptive response to its complex, multiaxial loading environment. However, these functional properties are associated with a location-dependent structure and composition that have not been fully elucidated. Therefore, the objective of this study was to determine the concentrations of types I, II and III collagen in six distinct regions of the SST and compare changes in collagen concentration across regions with local changes in mechanical properties. We hypothesized that type I collagen content would be high throughout the tendon, type II collagen would be restricted to regions of compressive loading and type III collagen content would be high in regions associated with damage. We further hypothesized that regions of high type III collagen content would correspond to regions with low tensile modulus and a low degree of collagen alignment. Although type III collagen content was not significantly higher in regions that are frequently damaged, all other hypotheses were supported by our results. In particular, type II collagen content was highest near the insertion while type III collagen was inversely correlated with tendon modulus and collagen alignment. The measured increase in type II collagen under the coracoacromial arch provides evidence of adaptation to compressive loading in the SST. Moreover, the structure-function relationship between type III collagen content and tendon mechanics established in this study demonstrates a mechanism for altered mechanical properties in pathological tendons and provides a guideline for identifying therapeutic targets and pathology-specific biomarkers.

RESUMO

Gastrocnemius and soleus flaps represent the workhorse local flaps to cover soft tissue defects of the proximal 1/3 and middle 1/3 of the leg, respectively. An important consideration before conducting a local flap is whether the flap can provide adequate coverage. The utility of the gastrocnemius flap can be increased using multiple techniques to increase the arc of rotation including the posterior midline approach, dissection at the pes anserinus and medial femoral condyle origin, scoring the fascia, and inclusion of a skin paddle. Concerning the soleus flap, the hemisoleus flap represents a technique to increase the arc of rotation. With a soleus flap, one must consider the soft tissue defect location, size, and perforator blood supply because these factors influence what soleus flap technique to use. This article discusses how to make the most out of gastrocnemius flaps and soleus flaps regarding maximizing coverage and ensuring successful flap outcome.

RESUMO

OBJECTIVE: The long-term performance of the quadriceps femoris muscle and physical function following surgical repair of a lower extremity fracture remains largely undefined. The purpose of this study was to investigate between-limb differences in quadriceps performance 12 months after surgical fixation of a lower extremity fracture. It was hypothesized that the injured limb would be significantly weaker, have a lower rate of torque development (RTD), and that there would be a reduced step-down performance compared to the uninjured limb 12 months after surgery. Additionally, this study sought to identify demographic, surgical, and psychological factors associated with poor quadriceps function 12 months after surgery. METHODS: Quadriceps performance was measured bilaterally in 95 participants (49 female), aged 42 (SD = 14.5) years, 12 months after surgical fixation of a lower extremity fracture. Isometric quadriceps strength and RTD were quantified using isometric dynamometry, and a timed step-down test was used to evaluate quadriceps performance. Independent predictor variables from the time of surgery were extracted from participants' medical records. Kinesiophobia was screened at the time of testing. Wilcoxon signed-rank tests and linear regression analyses were used to assess between-limb differences in quadriceps performance and to determine factors associated with quadriceps performance 12 months after surgery. RESULTS: Significant between-limb differences in each measure of quadriceps performance were identified (peak torque involved: 1.37 [0.71] Nm × kg-1; uninvolved: 1.87 [0.74] Nm × kg-1; RTD involved: 4.16 [2.75] Nm × kg-1 × s-1; uninvolved: 6.10 [3.02] Nm × kg-1 × × -1; and single-leg step-downs involved: 12.6 [5.0]; uninvolved: 21.7 [14.8]). Female biological sex, external fixation, and kinesiophobia at 12 months were associated with reduced after-surgery quadriceps performance outcomes. CONCLUSION: Quadriceps performance is impaired 12 months after surgical repair of a lower extremity fracture, particularly in female participants, in cases requiring external fixation, and in those with higher kinesiophobia 12 months after surgery. IMPACT: Because long-term quadriceps weakness negatively impacts functional mobility, targeted strengthening should be emphasized after surgical repair of lower extremity fracture.

RESUMO

While tendons typically undergo primary tensile loading, the human supraspinatus tendon (SST) experiences substantial amounts of tension, compression, and shear in vivo. As a result, the functional roles of the extracellular matrix components, in particular the proteoglycans (PGs), are likely complex and important. The goal of this study was to determine the PG content in specific regions of the SST that exhibit differing mechanical function. The concentration of aggrecan, biglycan, and decorin was determined in six regions of the human SST using immunochemical techniques. We hypothesized that aggrecan concentrations would be highest in areas where the tendon likely experiences compression; biglycan levels would be highest in regions likely subjected to injury and/or active remodeling such as the anterior regions; decorin concentrations would be highest in regions of greatest tensile stiffness. Our results generally supported these hypotheses and demonstrated that aggrecan and biglycan share regional variability, with increased concentration in the anterior and posterior regions and smaller concentration in the medial regions. Decorin, however, was in high concentration throughout all regions. The data presented in this study represent the first regional measurements of PG in the SST. Together with our previous regional measurements of mechanical properties, these data can be used to evaluate SST structure-function relationships. With knowledge of the differences in specific PG content, their spatial variations in the SST, and their relationships to tendon mechanics, we can begin to associate defects in PG content with specific pathology, which may provide guidance for new therapeutic interventions.

RESUMO

OBJECTIVE: Pain is a common outcome after lower extremity fracture (LEF) requiring surgical fixation. Although psychosocial characteristics have meaningful associations with adverse outcomes, no studies have evaluated how psychosocial characteristics throughout recovery are associated with pain outcomes. The primary purpose of this study was to determine whether psychosocial characteristics are early risk factors for pain outcomes in patients following LEF who have no history of chronic pain. METHODS: Participants, 122 patients with a LEF, consented to this single-center, prospective cohort study. Measurements of depression, pain self-efficacy, pain catastrophizing, and fear of movement were completed at 1 week, 6 weeks, 3 months, 6 months, and 12 months after LEF. Chronic pain development and pain intensity were assessed at 12 months. Univariate analyses assessing the difference between means and corresponding effect sizes were evaluated between those individuals with and without chronic pain at 12 months. Separate logistic and linear regression models using psychosocial scores at each time point were used to determine the association with the development of chronic pain and pain intensity, respectively. RESULTS: Of 114 patients (93.4%) who completed the study, 51 (45%) reported chronic pain at 12 months. In the univariate analysis, all psychosocial variables at 6 weeks, 3 months, 6 months, and 12 months were significantly different between those with and those without chronic pain at 12 months (Cohen d range = 0.84 to 1.65). In the multivariate regression models, all psychosocial variables at 6 weeks, 3 months, and 6 months were associated with chronic pain development (odds ratio range = 1.04 to 1.22) and pain intensity (ß range = .05 to .14) at 12 months. CONCLUSION: Psychosocial scores as early as 6 weeks after surgery are associated with pain outcomes 12 months after LEF. IMPACT: Physical therapists should consider adding psychosocial screening throughout recovery after LEF to identify patients at increased risk for long-term pain outcomes.

RESUMO

OBJECTIVE: To determine whether the use of a multimodal analgesic protocol reduced short-term and long-term opioid use in patients hospitalized after orthopaedic trauma. DESIGN: Retrospective pre-post intervention study. SETTING: Regional, academic, Level 1 trauma center in Central Kentucky. PATIENTS/PARTICIPANTS: Patients were hospitalized after orthopaedic injury before (n = 393) and after (n = 378) the implementation of a multimodal analgesic protocol. INTERVENTION: The intervention involved a multimodal analgesic protocol consisting of acetaminophen, ibuprofen/ketorolac, gabapentinoids, skeletal muscle relaxants, and standardized doses of opioids plus standardized pain management education before hospital discharge. MAIN OUTCOME MEASUREMENTS: End points included discharge opioid prescription, days' supply and daily morphine milligram equivalent (MME), and long-term opioid use after hospitalization. Opioid use in the 90 days before and after hospitalization was assessed using state prescription drug monitoring program data. RESULTS: Discharge opioid prescription rates were similar in the intervention and control cohorts [79.9% vs. 78.4%, odds ratio (OR) 1.30 (0.83-2.03), P = 0.256]. Patients in the intervention cohort received a shorter days' supply [5.7 ± 4.1 days vs. 8.1 ± 6.2 days, rate ratio 0.70 (0.65-0.76), P < 0.001] and lower average daily MME [34.8 ± 24.9 MME vs. 51.5 ± 44.0 MME, rate ratio 0.68 (0.62-0.75), P < 0.001]. The incidence of long-term opioid use was also significantly lower in the intervention cohort [7.7% vs. 12.0%, OR 0.53 (0.28-0.98), P = 0.044]. CONCLUSIONS: Implementation of a multimodal analgesic protocol was associated with reductions in both short-term and long-term opioid use, including long-term opioid therapy, after orthopaedic trauma. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

The Toolkit for Optimal Recovery (TOR) is a mind-body program for patients with acute orthopedic injuries who are at risk for persistent pain/disability. In preparation for a multisite feasibility trial of TOR at three orthopedic trauma centers, we aim to qualitatively identify barriers and facilitators to study implementation and strategies to mitigate the implementation barriers and leverage facilitators.We conducted 18 live video focus groups among providers and three one-on-one interviews with department chiefs at Level 1 trauma centers in three geographically diverse sites (N = 79 participants). Using a content analysis approach, we detected the site-specific barriers and facilitators of implementation of TOR clinical trial. We organized the data according to 26 constructs of the Consolidated Framework for Implementation Research (CFIR), mapped to three Proctor implementation outcomes relevant to the desired study outcomes (acceptability, appropriateness, and feasibility). Across the three sites, we mapped six of the CFIR constructs to acceptability, eight to appropriateness, and three to feasibility. Prominent perceived barriers across all three sites were related to providers' lack of knowledge/comfort addressing psychosocial factors, and organizational cultures of prioritizing workflow efficiency over patients' psychosocial needs (acceptability), poor fit between TOR clinical trial and the fast-paced clinic structure as well as basic needs of some patients (appropriateness), and limited resources (feasibility). Suggestions to maximize the implementation of the TOR trial included provision of knowledge/tools to improve providers' confidence, streamlining study recruitment procedures, creating a learning collaborative, tailoring the study protocol based on local needs assessments, exercising flexibility in conducting research, dedicating research staff, and identifying/promoting champions and using novel incentive structures with regular check-ins, while keeping study procedures as nonobtrusive and language as de-stigmatizing as possible. These data could serve as a blueprint for implementation of clinical research and innovations in orthopedic and other medical settings.

RESUMO

OBJECTIVE: To determine whether pre-existing psychiatric disorder is associated with potentially unnecessary fasciotomy. DESIGN: Retrospective cohort study. SETTING: Academic Level-1 trauma center. PATIENTS: All the patients with orthopaedic trauma undergoing leg fasciotomy at an academic Level I trauma center from 2006 to 2020. INTERVENTION: Pre-existing diagnosis of psychiatric disorder. MAIN OUTCOME MEASUREMENTS: Early primary wound closure and delayed primary wound closure. RESULTS: In total, 116 patients were included. Twenty-seven patients (23%) had a pre-existing diagnosis of psychiatric disorder with 13 having anxiety, 14 depression, 5 bipolar disorder, and 2 ADHD. Several patients had multiple diagnoses. Fifty-one patients (44%) had early primary closure (EPC), and 65 patients (56%) had delayed primary closure. Of patients with a psychiatric disorder, 52% received EPC compared with 42% of patients without a disorder, P = 0.38. This lack of a strong association did not seem to vary across specific psychiatric conditions. After adjusting for sex, age, injury type, and substance abuse, there was still no significant association between a psychiatric disorder and EPC with an odds ratio of 1.08 (95% CI, 0.43-2.75). CONCLUSIONS: Among patients with orthopaedic trauma undergoing emergent fasciotomy for acute compartment syndrome, a psychiatric disorder was not associated with a significantly increased rate of possibly unnecessary fasciotomy. Given the potential for a psychiatric condition to complicate the diagnosis of acute compartment syndrome, this data is somewhat reassuring; however, there remains a need for continued vigilance in treating patients with psychiatric conditions and research in this area. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
