Observation versus Cast Treatment of Toddler's Fracture: A Prospective Pilot Study.

"Toddler's fractures" are common in the pediatric population. Traditional treatment recommends casting these fractures, although with their inherent stability, may be unnecessary. This study evaluated if toddler's fractures can be treated with observation alone as opposed to casts. A prospective pilot study was performed with randomization and observational arms. Children were placed in short casts or observed without immobilization. A 21-day log was given to families to record walking. Follow up with radiographs occurred at 3 and 12 weeks. Twenty-one patients enrolled, three randomized and 18 chose their treatment. Thirteen patients were casted, and eight went without immobilization. Ambulation time was similar between groups (p = 0.260). Three without immobilization returned early but none converted to cast. All fractures healed uneventfully. There were no cast complications. Toddler's fractures treated with or without cast immobilization appears to be safe and effective but should be a shared decision between physician and parents.

Midshaft clavicle fractures: is anterior plating an acceptable alternative to superior plating?

PURPOSE: The purpose of this study was to determine whether anterior plating is better tolerated than superior plating for midshaft clavicle fractures. METHODS: This was a prospective non-randomized observational cohort study following operative vs. non-operative management of clavicle fractures from 2003 to 2018 at 7 level 1 academic trauma centers in the USA. The subset of patients treated with plate and screws is the basis for this comparative study. Adults aged 18-85 with closed clavicle fractures displaced over 100% or shortened by more than 1.5 cm were eligible for enrollment. Patients were followed for 2 years following enrollment. Allowable fixation methods at the discretion of the surgeon consisted of anterior-inferior or superior plating. A total of 412 patients were enrolled. Of these, 192 patients received either superior or anterior plating for a displaced clavicle fracture with complete documented prospective research forms capturing type of plating technique. The primary outcome measure was hardware removal (HWR). Secondary outcomes were Disability of the Arm Shoulder and Hand (DASH) score and Visual Analog Pain (VAP) score, and satisfaction score (1 = high satisfaction; 5 = low satisfaction). RESULTS: There was no difference in HWR rates (7.1% superior 9/127; 6.2% anterior 4/65, p = 0.81), VAP score (mean 1.5 SD 1.0 superior; mean 1.7 SD 0.6 anterior, p = 0.21), DASH score (mean 7.5 SD 12.4 superior; mean 5.2 SD 15.2 anterior; p = 0.18) or satisfaction score (mean 1.6 SD 1.0 superior; mean 1.7 SD 0.60 anterior, p = 0.18). CONCLUSION: There is no difference in HWR rates or functional outcomes when using a superior vs. anterior plating technique.

Impact of an Opioid Stewardship Initiative Involving Early Conversion to Oral Narcotics in Postoperative Orthopaedic Patients.

The objective of this study was to determine if the implementation of an opioid stewardship initiative involving early conversion to oral opioids improves outcomes in postoperative orthopaedic patients. This single-center retrospective chart review compared adult patients undergoing lower extremity orthopaedic procedures during a specified six-month time period. The primary outcome was total opioid utilization in morphine milligram equivalence (MME) at 48-hours post-surgery. Four hundred ninety-five patients were included in the study, 233 in the intervention group and 262 in the pre-intervention group. The average pain scores at 12, 24 and 48 hours postoperatively were similar among the two groups. After a multivariate linear regression was performed, a 22.9 MME reduction was estimated in the post-implementation group compared to the pre-implementation group (p = 0.003). Based on these results, it appears that converting from intravenous to oral narcotics 24-hours post-orthopaedic surgery reduces total mean MMEs while providing similar pain control.

How Successful Is Antibiotic Treatment for Superficial Surgical Site Infections After Open Fracture? A Fluid Lavage of Open Wounds (FLOW) Cohort Secondary Analysis.

BACKGROUND: Although many studies report the incidence and prevalence of surgical site infections (SSIs) after open fractures, there is limited information on the treatment and subsequent outcomes of superficial SSIs in patients with open fractures. Additionally, clinical studies describing the factors that are associated with persistent infection after nonoperative treatment with antibiotics for patients with superficial SSIs are lacking. QUESTIONS/PURPOSES: Therefore, we asked: (1) What proportion of patients with superficial SSIs after open fracture treatment developed persistent infection after nonoperative treatment (that is, treatment with antibiotics alone)? (2) What risk factors are associated with SSIs that do not resolve with nonoperative (antibiotic) treatment? As a secondary objective, we planned to analyze the microbiological information about participants wound cultures, when these were available, and the proportion of positive cultures for patients whose SSIs were not resolved by antibiotics alone. METHODS: This is a secondary analysis of the Fluid Lavage of Open Wounds (FLOW) trial dataset. The FLOW trial included 2445 patients with operatively managed open fractures. FLOW participants who had a nonoperatively managed superficial SSI diagnosed in the 12 months post-fracture were included in this analysis. Superficial SSIs were diagnosed in 168 participants within 12 months of their fracture. Of these, 83% (139) had their superficial SSI treated with antibiotics alone. Participants were grouped into two categories: (1) 97 participants whose treatment with antibiotics alone resolved the superficial SSI and (2) 42 participants whose treatment with antibiotics alone did not resolve the SSI (defined as undergoing surgical management or the SSI being unresolved at latest follow-up [12-months post-fracture for the FLOW trial]). Of the participants whose treatment with antibiotics alone resolved the SSI, 92% (89 of 97) had complete follow-up, 6% (6 of 97) were lost to follow-up before 12 months, 1% (1 of 97) withdrew consent from the study before 12 months, and 1% (1 of 97) experienced mortality before 12 months. Of the participants whose treatment with antibiotics alone did not resolve the SSI, 90% (38 of 42) had complete follow-up, 7% (3 of 42) were lost to follow-up before 12 months, and 2% (1 of 42) withdrew consent from the study before 12 months. A logistic binary regression analysis was conducted to identify factors associated with persistent infection despite superficial SSI antibiotic treatment. Based on biologic rationale and previous evidence, we identified a priori 13 potential factors (corresponding to 14 levels) to be included in the regression model. RESULTS: The antibiotic treatment resolved the superficial SSI in 70% (97 of 139) of patients and did not resolve the SSI in 30% (42 of 139). After controlling for potential confounding variables, such as age, fracture severity, and time from injury to initial surgical irrigation and débridement, superficial SSIs diagnosed later in follow-up were associated with antibiotics not resolving the SSI (odds ratio 1.05 [95% CI 1.004 to 1.009] for every week of follow-up; p = 0.03). Sex, fracture pattern, and wound size were not associated with antibiotics not resolving the SSI. CONCLUSIONS: Our secondary analysis of prospectively collected FLOW data suggests that antibiotics alone can be an appropriate treatment option when treating superficial SSIs after an open fracture wound, especially when promptly diagnosed. Further research with longer follow-up time is needed to better identify the natural history of superficial SSIs and possibly some dormant or subclinical infections to help clinicians in the treatment decision-making process. LEVEL OF EVIDENCE: Level III, therapeutic study.

The Dislocated Hip on CT Scan: An Argument for the Initial Pelvic Radiograph in Trauma Patients.

This study evaluated the frequency in which a hip dislocation is first diagnosed by computed tomography (CT) scan. A retrospective review was conducted of orthopaedic trauma patients presenting with hip dislocation to a Level 1 trauma center over three years. We recorded whether the patient first received pelvic radiograph (PXR) or CT scan of the pelvis, if the patient underwent closed reduction of the hip prior to CT scan, and if repeat pelvis CT scan was done. Of 83 hip dislocations, 64 patients were sent to CT scanner dislocated; 19 patients first had PXR and underwent closed reduction of the hip prior to CT scan. By obtaining a PXR, reducing the hip prior to CT, the incidence of repeat CT scan decreased from 37% to 11% (p = 0.046). By diagnosing hip dislocation, reducing prior to CT scan, repeat scans can be reduced, thus decreasing cost and radiation exposure to patients.

A Trial of Wound Irrigation in the Initial Management of Open Fracture Wounds.

BACKGROUND: The management of open fractures requires wound irrigation and débridement to remove contaminants, but the effectiveness of various pressures and solutions for irrigation remains controversial. We investigated the effects of castile soap versus normal saline irrigation delivered by means of high, low, or very low irrigation pressure. METHODS: In this study with a 2-by-3 factorial design, conducted at 41 clinical centers, we randomly assigned patients who had an open fracture of an extremity to undergo irrigation with one of three irrigation pressures (high pressure [>20 psi], low pressure [5 to 10 psi], or very low pressure [1 to 2 psi]) and one of two irrigation solutions (castile soap or normal saline). The primary end point was reoperation within 12 months after the index surgery for promotion of wound or bone healing or treatment of a wound infection. RESULTS: A total of 2551 patients underwent randomization, of whom 2447 were deemed eligible and included in the final analyses. Reoperation occurred in 109 of 826 patients (13.2%) in the high-pressure group, 103 of 809 (12.7%) in the low-pressure group, and 111 of 812 (13.7%) in the very-low-pressure group. Hazard ratios for the three pairwise comparisons were as follows: for low versus high pressure, 0.92 (95% confidence interval [CI], 0.70 to 1.20; P=0.53), for high versus very low pressure, 1.02 (95% CI, 0.78 to 1.33; P=0.89), and for low versus very low pressure, 0.93 (95% CI, 0.71 to 1.23; P=0.62). Reoperation occurred in 182 of 1229 patients (14.8%) in the soap group and in 141 of 1218 (11.6%) in the saline group (hazard ratio, 1.32, 95% CI, 1.06 to 1.66; P=0.01). CONCLUSIONS: The rates of reoperation were similar regardless of irrigation pressure, a finding that indicates that very low pressure is an acceptable, low-cost alternative for the irrigation of open fractures. The reoperation rate was higher in the soap group than in the saline group. (Funded by the Canadian Institutes of Health Research and others; FLOW ClinicalTrials.gov number, NCT00788398.).

Immobilization Versus Observation in Children With Toddler's Fractures: A Retrospective Review.

While long leg casts have been historically recommended for immobilization of toddler's fractures, short leg casts are often used by treating physicians. Others question whether any immobilization is necessary because of the internal stability provided by the thickened periosteum of pediatric bones. The purpose of this study is to review the results of toddler's fractures treated with long leg casts, short leg casts, or without immobilization. Eighty-five patients were included in a retrospective review of nondisplaced spiral or oblique tibial shaft fractures in children under 6 years old from 2007 to 2012. Treatments included long leg casts (19), short leg casts (59), and no immobilization (7). Average time to ambulation was 15.5 days. There were 11 casting complications. Only one patient, in a short leg cast, had measurable displacement or angulation. There were no complications reported in the nonimmobilized group. The results suggest that toddler's fractures can be effectively treated with short leg casts or without immobilization. (Journal of Surgical Orthopaedic Advances 27(2):142-147, 2018).

Does Traction Decrease the Need for Open Reduction in Femoral Shaft Fractures Treated Within 24 Hours?

This study evaluates whether preoperative skeletal traction reduces the need for open reduction in femoral shaft fractures treated with intramedullary nailing (IMN) within 24 hours. A retrospective review was conducted of femoral shaft fractures undergoing IMN within 1 day of admission. Primary outcome was an open reduction at the time of IMN. Secondary outcomes were blood loss and transfusion requirements. One hundred eighty-four patients were analyzed, 106 in the knee immobilizer group and 78 in the skeletal traction group. Skeletal traction did not reduce the need for an open reduction. The knee immobilizer group required open reduction in 13% (14/106) compared with 14% (11/78) in the skeletal traction group, which was not significant (p $=$ .89). Blood loss and transfusion rates were similar between groups. Skeletal traction does not appear to reduce the need for open reduction at the time of IMN for femoral shaft fractures treated within 1 day of admission.

Interactive Tools for Measuring Visual Scanning Performance and Reaction Time.

Occupational therapists are constantly searching for engaging, high-technology interactive tasks that provide immediate feedback to evaluate and train clients with visual scanning deficits. This study examined the relationship between two tools: the VISION COACH™ interactive light board and the Functional Object Detection© (FOD) Advanced driving simulator scenario. Fifty-four healthy drivers, ages 21-66 yr, were divided into three age groups. Participants performed braking response and visual target (E) detection tasks of the FOD Advanced driving scenario, followed by two sets of three trials using the VISION COACH Full Field 60 task. Results showed no significant effect of age on FOD Advanced performance but a significant effect of age on VISION COACH performance. Correlations showed that participants' performance on both braking and E detection tasks were significantly positively correlated with performance on the VISION COACH (.37 < r < .40, p < .01). These tools provide new options for therapists.

Correction of Tibial Torsion in Children With Cerebral Palsy by Isolated Distal Tibia Rotation Osteotomy: A Short-term, In Vivo Anatomic Study.

BACKGROUND: Excessive internal or external tibial torsion is frequently present in children with cerebral palsy. Several surgical techniques have been described to correct excessive tibial torsion, including isolated distal tibial rotation osteotomy (TRO). The anatomic changes surrounding this technique are poorly understood. The goal of the study was to examine the anatomic relationship between the tibia and fibula following isolated distal TRO in children with cerebral palsy. METHODS: Twenty patients with 29 limbs were prospectively entered for study. CT scans of the proximal and distal tibiofibular (TF) articulations were obtained preoperatively, at 6 weeks, and 1 year postoperatively. Measurements of tibia and fibula torsion were performed at each interval. Qualitative assessments of proximal and distal TF joint congruency were also performed. RESULTS: The subjects with internal tibia torsion (ITT, 19 limbs) showed significant torsional changes for the tibia between preoperative, postoperative, and 1 year time points (mean torsion 13.21, 31.05, 34.84 degrees, respectively). Measurement of fibular torsion in the ITT treatment group also showed significant differences between time points (mean -36.77, -26.77, -18.54 degrees, respectively). Proximal and distal TF joints remained congruent at all time points in the study.Subjects with external tibia torsion (ETT, 10 limbs) showed significant differences between preoperative and postoperative tibial torsion, but not between postoperative and 1 year (mean torsion 54, 19.3, 23.3 degrees, respectively). Measurement of fibular torsion in the ETT treatment group did not change significantly between preoperative and postoperative, but did change significantly between postoperative and 1 year (mean torsion -9.8,-16.9, -30.7 degrees, respectively). Nine of 10 proximal TF joints were found to be subluxated at 6 weeks postoperatively. At 1 year, all 9 of these joints had reduced. CONCLUSIONS: Correction of ITT by isolated distal tibial external rotation osteotomy resulted in acute external fibular torsion. The fibular torsion alignment remodeled over time to accommodate the corrected tibial torsional alignment and reduce the strain associated with the plastic deformity of the fibula. Correction of ETT by isolated distal internal TRO resulted in acute subluxation of the proximal TF articulation in almost all cases. Subsequent torsional remodeling of the fibula resulted in correction of the TF subluxation in all cases. Acute correction of TT by isolated distal TRO occurs by distinct mechanisms, based upon the direction of rotational correction. LEVEL OF EVIDENCE: Level II-Diagnostic.

Droplet Digital™ PCR quantitation of HER2 expression in FFPE breast cancer samples.

UNLABELLED: The human epidermal growth factor receptor 2 (HER2, also known as erbB2) gene is involved in signal transduction for cell growth and differentiation. It is a cell surface receptor tyrosine kinase and a proto-oncogene. Overexpression of HER2 is of clinical relevance in breast cancer due to its prognostic value correlating elevated expression with worsening clinical outcome. At the same time, HER2 assessment is also of importance because successful anti-tumor treatment with Herceptin® is strongly correlated with HER2 overexpression in the tumor (approximately 30% of all breast tumors overexpress HER2). In a comprehensive national study, Wolff et al. [1] state that "Approximately 20% of current HER2 testing may be inaccurate" which underscores the importance of developing more accurate methods to determine HER2 status. Droplet Digital™ PCR (ddPCR™) has the potential to improve upon HER2 measurements due to its ability to quantitate DNA and RNA targets with high precision and accuracy. Here we present a study which investigates whether ddPCR can be used to assess HER2 transcript levels in formalin-fixed paraffin embedded (FFPE) human breast tumors and whether these ddPCR measurements agree with prior assessments of these same samples by pathologists using immunohistochemistry (IHC) and in some cases fluorescence in situ hybridization (FISH). We also determined the copy number of HER2 in these samples as compared to the CEP17 reference gene. RESULTS: Clinical FFPE samples were successfully studied using ddPCR and compared to results from standard FISH and IHC methodology. The results demonstrate that ddPCR can rank order the samples in complete agreement with the current standard methods and that ddPCR has the added benefit of providing quantitative results, rather than relying on the expert skill of a seasoned pathologist for determination.

Multicenter, Prospective, Observational Study of Nonoperative Versus Operative Treatment for High-Energy Midshaft Clavicle Fractures.

OBJECTIVES: Evaluate if nonoperative or operative treatment of displaced clavicle fractures delivers reduced rates of nonunion and improved Disability of the Arm, Shoulder, and Hand (DASH) scores. DESIGN: Multicenter, prospective, observational. SETTING: Seven Level 1 Trauma Centers in the United States. PATIENT SELECTION CRITERIA: Adults with closed, displaced (100% displacement/shortened >1.5 cm) midshaft clavicle fractures (Orthopaedic Trauma Association 15.2) were treated nonoperatively, with plates and screw fixation, or with intramedullary fixation from 2003 to 2018. OUTCOME MEASURES AND COMPARISONS: DASH scores (2, 6 weeks, 3, 6, 12, and 24 months), reoperation, and nonunion were compared between the nonoperative, plate fixation, and intramedullary fixation groups. RESULTS: Four hundred twelve patients were enrolled, with 203 undergoing plate fixation, 26 receiving intramedullary fixation, and 183 treated nonoperatively. The average age of the nonoperative group was 40.1 (range 18-79) years versus 35.8 (range 18-74) in the plate group and 39.3 (range 19-56) in the intramedullary fixation group (P = 0.06). One hundred forty (76.5%) patients in the nonoperative group were male compared with 154 (75.9%) in the plate group and 18 (69.2%) in the intramedullary fixation group (P = 0.69). All groups showed similar DASH scores at 2 weeks, 12 months, and 24 months (P > 0.05). Plate fixation demonstrated better DASH scores (median = 20.8) than nonoperative (median = 28.3) at 6 weeks (P = 0.04). Intramedullary fixation had poorer DASH scores at 6 weeks, 3 months, and 6 months than plate fixation and worse DASH scores than nonoperative at 6 months (P < 0.05). The nonunion rate for nonoperative treatment (14.6%) was significantly higher than the plate group (0%) (P < 0.001). CONCLUSIONS: Operative treatment of displaced clavicle fractures provided lower rates of nonunion than nonoperative treatment. Except at 6 weeks, no difference was observed in DASH scores between plate fixation and nonoperative treatment. Intramedullary fixation resulted in worse DASH scores than plate fixation at 6 weeks, 3 months, and 6 months and worse DASH scores than nonoperative at 6 months. Implant removal was the leading reason for reoperation in the plate and intramedullary fixation groups, whereas surgery for nonunion was the primary reason for surgery in the nonoperative group. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

The Impact of Virtual Reality on Anxiety and Pain During US-Guided Breast Biopsies: A Randomized Controlled Clinical Trial.

OBJECTIVE: To investigate the efficacy of immersive virtual reality (VR) in combination with standard local anesthetic for mitigating anxiety and pain during US-guided breast biopsies compared to local anesthetic alone. METHODS: Patients scheduled for US-guided biopsy were invited to participate. Eligible patients were females 18 years of age or older. Patients were randomized to VR or control group at a 1:1 ratio. Patients in the VR group underwent biopsy with the addition of a VR experience and patients in the control group underwent usual biopsy. Patient-perceived levels of anxiety and pain were collected before and after biopsy via the State-Trait Anxiety Inventory (STAI) and Visual Analog Scale (VAS). Physiological data were captured during biopsy using a clinically validated wristband. Differences in anxiety, pain, and physiologic data were compared between the VR and control group. RESULTS: Sixty patients were enrolled. After excluding 2 patients with VR device malfunction, there were 29 patients in the VR and 29 patients in the control group for analysis. The VR group had reduced anxiety compared to the control group based on postintervention STAI (P <.001) and VAS (P = .036). The VR group did not have lower pain based on postintervention VAS (P = .555). Physiological measures showed higher RR intervals and decreased skin conductance levels, which are associated with lower anxiety levels in the VR group. CONCLUSION: Use of VR in addition to standard local anesthetic for US-guided breast biopsies was associated with reduced patient anxiety. Virtual reality may be a useful tool to improve the patient biopsy experience.

Disease-associated comorbidities, medication records and anthropometric measures in adults with Duchenne muscular dystrophy.

We investigated the comorbidities, associated factors, and the relationship between anthropometric measures and respiratory function and functional abilities in adults with Duchenne muscular dystrophy (DMD). This was a single-centre cross-sectional study in genetically diagnosed adults with DMD (>16 years old). Univariate and multivariate analyses identified factors associated with dysphagia, constipation, Body Mass Index (BMI), and weight. Regression analysis explored associations between BMI, weight, and respiratory/motor abilities. We included 112 individuals (23.4 ± 5.2 years old), glucocorticoid-treated 66.1 %. The comorbidities frequency was 61.6 % scoliosis (61.0 % of them had spinal surgery), 36.6 % dysphagia, 36.6 % constipation, and 27.8 % urinary conditions. The use of glucocorticoids delayed the time to spinal surgery. The univariate analysis revealed associations between dysphagia and constipation with age, lack of glucocorticoid treatment, and lower respiratory and motor function. In the multivariate analysis, impaired cough ability remained as the factor consistently linked to both conditions. Constipation associated with lower BMI and weight. BMI and weight positively correlated with respiratory parameters, but they did not associate with functional abilities. Glucocorticoids reduce the frequency of comorbidities in adults with DMD. The ability to cough can help identifying dysphagia and constipation. Lower BMI and weight in individuals with DMD with compromised respiratory function may suggest a higher calories requirement.

Droplet digital PCR measurement of HER2 copy number alteration in formalin-fixed paraffin-embedded breast carcinoma tissue.

BACKGROUND: Human epidermal growth factor receptor 2 (HER2) testing is routinely performed by immunohistochemistry (IHC) and/or fluorescence in situ hybridization (FISH) analyses for all new cases of invasive breast carcinoma. IHC is easier to perform, but analysis can be subjective and variable. FISH offers better diagnostic accuracy and added confidence, particularly when it is used to supplement weak IHC signals, but it is more labor intensive and costly than IHC. We examined the performance of droplet digital PCR (ddPCR) as a more precise and less subjective alternative for quantifying HER2 DNA amplification. METHODS: Thirty-nine cases of invasive breast carcinoma containing ≥30% tumor were classified as positive or negative for HER2 by IHC, FISH, or both. DNA templates for these cases were prepared from formalin-fixed paraffin-embedded (FFPE) tissues to determine the HER2 copy number by ddPCR. ddPCR involved emulsifying hydrolysis probe-based PCR reaction mixtures containing the ERBB2 [v-erb-b2 erythroblastic leukemia viral oncogene homolog 2, neuro/glioblastoma derived oncogene homolog (avian); also known as HER2] gene and chromosome 17 centromere assays into nanoliter-sized droplets for thermal cycling and analysis. RESULTS: ddPCR distinguished, through differences in the level of HER2 amplification, the 10 HER2-positive samples from the 29 HER2-negative samples with 100% concordance to HER2 status obtained by FISH and IHC analysis. ddPCR results agreed with the FISH results for the 6 cases that were equivocal by IHC analyses, confirming 2 of these samples as positive for HER2 and the other 4 as negative. CONCLUSIONS: ddPCR can be used as a molecular-analysis tool to precisely measure copy number alterations in FFPE samples of heterogeneous breast tumor tissue.

Evaluating safe time to discharge after closed reduction and percutaneous pinning of uncomplicated type III supracondylar humerus fractures: a single-center retrospective review.

The purpose of this retrospective study was to review complications following closed reduction, percutaneous pinning of isolated, type III supracondylar fractures without associated injuries to evaluate if patients may be discharged safely on the day of surgery. We performed a retrospective chart and radiographic review of patients with isolated Gartland type III supracondylar humerus fractures who underwent closed reduction and percutaneous pinning over a 4-year period. We reviewed admission time to the emergency department, time and length of surgery, time to discharge, postoperative complications, readmission rate and office visits. Of the 110 patients included, 19 patients were discharged in less than 6 h, 45 patients between 6 and 12 h and 46 patients greater than 12 h. A total of 61 patients were discharged on the same day as surgery and 49 were discharged the next day. There were 11 postoperative complications. No postoperative complications were found in patients discharged less than 6 hours from surgery. For patients discharged between 6 and 12 hours postoperatively, one patient returned to the office earlier than scheduled. The result of our review suggests that patients can be safely discharged within the 12-h postoperative period with no increased risk of complications. This is contingent upon the patient having a stable neurovascular examination, pain control and caregiver's comfort level. This can decrease medical cost, family stress and burden to the hospital system. Time to discharge should still be evaluated on a case-by-case basis after evaluating medical and social barriers.

High Complication Rate After Percutaneous Screw Fixation for Valgus-Impacted Femoral Neck Fractures Without Sagittal Malalignment.

OBJECTIVES: To evaluate the rate of reoperation in patients without sagittal plane malalignment who underwent percutaneous screw fixation of a valgus-impacted femoral neck fracture. DESIGN: Retrospective case series. SETTING: Two Level 1 academic trauma centers. PATIENTS AND INTERVENTION: Two hundred seven patients >50 years of age with valgus-impacted femoral neck fractures treated with at least 3 large-diameter (>6.5 mm) cancellous screws from 2013 to 2019. Patients were excluded if there was a sagittal plane fracture deformity. MAIN OUTCOME MEASUREMENTS: The primary outcome was reoperation. Secondary outcomes considered "major complications" included: avascular necrosis, varus collapse or implant cutout, nonunion, deep infection, and hematoma requiring reoperation. Surgical fixation strategies (screw configuration, aim) and implant type (partial vs. fully threaded cancellous screws) were secondarily compared. RESULTS: Average patient age was 77 years, and median clinical follow-up was 658 days. Thirty-one patients (15%) required reoperation, and the major complication rate was 17.3% (36 complications in 33 patients). Logistic regression analysis demonstrated a higher risk of reoperation with constructs consisting of all partially threaded screws (17.0%) compared with the use of at least 1 fully threaded screw (7.5%) when an inverted triangle configuration was used (odds ratio, 2.50; 95% CI, 0.81-7.77). CONCLUSIONS: This study demonstrated a relatively high rate of reoperation and major complications in patients with valgus-impacted femoral neck fractures without sagittal malalignment treated with in situ percutaneous screw fixation. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Infection Rate in Type I Open Distal Radius Fractures Surgically Treated >24 Hours Post-Injury: A Comparison Study.

PURPOSE: To determine how time to surgical debridement and fixation affects infection and complication rate in type I open distal radius fractures by comparing patients treated within 24 hours with those treated >24 hours post-injury. METHODS: A retrospective review identified 62 patients who sustained a type I open distal radius fracture that was treated surgically. Patients were stratified into groups based on time to surgical intervention. An additional analysis was performed on patients with an isolated type I open distal radius fracture treated as an inpatient or outpatient. The primary outcome measure was infection rate. Secondary outcome measures were complications, reoperations, and readmissions. RESULTS: Thirty-eight patients underwent surgery ≤24 hours post-injury at an average of 14 hours. Twenty-four patients underwent surgery >24 hours post-injury at an average of 72 hours. There were a total of 9 complications in 8 patients (14.5%). The overall infection rate was 1.6%, with only 1 deep infection occurring in the group treated ≤24 hours post-injury. There were 7 reoperations (11.3%) and 1 readmission (1.6%). No differences were found between groups in any outcome measure. In the 27 patients with an isolated fracture, there were no differences in any outcome measure when treated as an inpatient or outpatient. CONCLUSIONS: We suggest that type I open distal radius fractures could be safely treated surgically >24 hours post-injury without increased risk of infection.

Fluid lavage of open wounds (FLOW): a multicenter, blinded, factorial pilot trial comparing alternative irrigating solutions and pressures in patients with open fractures.

BACKGROUND: Open fractures are an important source of morbidity and are associated with delayed union, nonunion, and infection. Preventing infection through meticulous irrigation and debridement is an important goal in management, and different lavage fluids and irrigation techniques (e.g., high- or low-pressure lavage) have been described for this purpose. However, there are a limited number of randomized trials comparing irrigating solutions or irrigating technique. We compared the use of castile soap versus normal saline and high- versus low-pressure pulsatile lavage on the rates of reoperations and complications in patients with open fracture wounds. METHODS: We conducted a multicenter, blinded, randomized 2 × 2 factorial pilot trial of 111 patients in whom an open fracture wound was treated with either castile soap solution or normal saline and either high- or low-pressure pulsatile lavage. The primary composite outcome of reoperation, measured at 12 months after initial operative procedure, included infection, wound healing problems, and nonunion. Planned reoperations were not included. Secondary outcomes included all infection, all wound healing problems, and nonunion as well as functional outcomes scores (EuroQol-5 dimensions and short form-12). RESULTS: Eighty-nine patients completed the 1-year follow-up. Among all patients, 13 (23%) in the castile soap group and 13 (24%) in the saline group had a primary outcome event (hazard ratio, 0.91, 95% confidence interval: 0.42-2.00, p = 0.52). Sixteen patients (28%) in the high-pressure group and 10 patients (19%) in the low-pressure group had a primary outcome event (hazard ratio 0.55, 95% confidence interval: 0.24-1.27, p = 0.17). Functional outcome scores showed no significant differences at any time point between groups. CONCLUSION: The fluid lavage of open wounds pilot randomized controlled trial demonstrated the possibility that the use of low pressure may decrease the reoperation rate for infection, wound healing problems, or nonunion. We have demonstrated the desirability and feasibility of a definitive trial examining the effects of alternative irrigation approaches.
