ABSTRACT
OBJECTIVE: Perioperative urinary tract infections (UTIs) are poorly studied among pediatric orthopedic surgical patients. We evaluated the incidence of and risk factors for UTI in a large volume of pediatric orthopedic surgical patients. METHODS: Children <18 who underwent orthopedic surgery between March 2015 and December 2018 were analyzed using our institution's National Surgical Quality Improvement Program (NSQIP) data. Demographic, perioperative and outcome data of patients who developed a UTI within 30 days of surgery were compared to patients without UTI. RESULTS: NSQIP data were available for 520 surgeries (324 girls and 196 boys). Median age at surgery was 13.5 years. A Foley was placed in 301/520 cases (88/196 boys and 213/324 girls) in 264 children. Six cases of UTI occurred within 30 days of surgery (1.2% of surgeries). The UTI rate among patients with a Foley was 2.3%, and among girls with a Foley was 2.8%. No UTIs occurred without a Foley, nor any in boys. All six occurred in the American Society of Anesthesiologists Class 2 females, ages 7-15 undergoing elective surgery with Foley for over 48â h. Factors associated with an increased odds of developing UTI included: higher BMI [OR, 1.12 (CI, 1.01-1.22; P â =â 0.03)], developmental delay [OR, 7.82 (CI, 1.40-43.7; P â =â 0.02)], structural central nervous system abnormality [OR, 17.5 (CI, 3.89-90.4; P â =â 0.01)], longer duration with Foley [OR, 1.68 (CI, 1.22-2.32; P â =â 0.002)] and hospital readmission within 30 days [OR 14.2 (CI, 2.32-87.3; P â =â 0.004)]. CONCLUSION: Risk of UTI is low after pediatric orthopedic surgery. Girls with comorbidities including structural central nervous system abnormality, developmental delay and higher BMI with prolonged Foley catheterization may have higher postoperative UTI risk. Level of Evidence: II.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic drastically altered children's activity patterns. Our goal was to investigate how COVID-19 affected demographics, injury characteristics, treatment patterns, follow-up, and outcomes in pediatric supracondylar humerus (SCH) fractures. METHODS: This was an Institutional Review Board-approved retrospective analysis of patients undergoing surgery for a SCH fracture from May to November 2019 (pre-COVID-19) and from May to November 2020 (during COVID-19) at 2 tertiary children's hospitals. Demographic information, injury characteristics, hospital course, and follow-up data were collected and compared. RESULTS: SCH fractures decreased by >50% from 2019 (149) to 2020 (72). Children in the 2020 cohort were younger (mean 5.2 y old) compared with 2019 (6.0 y old) ( P =0.019). Mechanism of injury was significantly different in 2020 ( P <0.001), as the proportion of trampoline and furniture fractures increased from 8% and 17% to 15% and 33%, respectively. The proportion of playground and monkey bar fractures decreased from 20% and 17% to 3% and 4%, respectively. Distribution of Gartland type and neurovascular injury rates were similar in 2019 and 2020 ( P =0.411 and 0.538). Time from emergency department admission to the operating room and duration of hospital admission were both unchanged from 2019 to 2020 ( P =0.864 and 0.363). The duration of postoperative follow-up in 2019 was 94.5 days compared with 72.8 days in 2020 ( P =0.122), as more pandemic patients were lost to follow up (22.5% vs. 35.2%, P =0.049). CONCLUSIONS: The demographics, mechanism of injury, and follow-up practices of pediatric SCH fractures changed significantly during the pandemic, likely because of school closures and lock-downs changing activity patterns. Different mechanisms of injury affected younger patients and reflected the new ways children played. Trampoline-related and furniture-related injuries overtook the classic playground falls as primary mechanism of injury. Despite the need for COVID-19 testing, there was no delay in time to the operating room. Hospitalization duration did not change, yet postoperative follow-up was shorter, and more patients were lost to follow up. Despite these stressors, outcomes remained excellent in most children. LEVEL OF EVIDENCE: Level III-Retrospective comparative study.

INTRODUCTION: Medial epicondyle fracture displacement is notoriously difficult to determine on conventional radiography, and follow-up computed tomography (CT) is often obtained to measure precise displacement. Another option for fracture characterization is digital tomosynthesis (DT), a technology providing high in-plane resolution of bony anatomy by acquiring multiple low-dose images in a linear arc. Advantages of DT include lower radiation exposure and lower cost than CT, rapid image acquisition, and a similar patient experience to conventional radiography. The digital application of tomosynthesis is relatively new and is integrated as an add-on feature with modern radiography equipment. This study compares DT, CT and conventional radiography for measurement accuracy in medial epicondyle fractures with the goal of determining relative accuracy in measuring medial epicondyle fracture displacement. METHODS: Medial epicondyle fractures were created in 5 cadaveric elbow specimens. Each specimen was imaged with conventional radiography, DT, and CT. True displacement measured by digital calipers was compared with "measured" displacement for each image acquisition. CT images included axial, sagittal, and coronal reformats. DT images of the elbow included anteroposterior (AP) longitudinal and transverse, lateral longitudinal and transverse, and axial longitudinal and transverse. Conventional radiographs included AP, lateral, and axial distal humerus images. Four physicians reviewed all images 3 months later. Each reviewer independently measured maximum apparent fracture displacement to the nearest 0.1 mm. Measurement accuracy was calculated as percent difference [(measured displacement-actual displacement)/actual displacement] for each acquisition. Mean, median, and SD for measurement accuracy were calculated. Two-tailed paired t tests were performed on each acquisition to compare the measurement accuracy. RESULTS: Compared with conventional radiographs, accuracy of DT was superior in AP longitudinal (P=0.03), AP transverse (P=0.01), axial longitudinal (P=0.0001), and axial transverse projections (P=0.001). Accuracy of CT was superior to conventional radiography in the AP projection (P=0.03), but was equivalent in the axial projection (P=0.9). Accuracy of CT was similar to DT in AP longitudinal (P=0.6), AP transverse (P=0.5), and axial longitudinal projections (P=0.07). Accuracy of DT in the axial transverse projection was superior to CT (P=0.03). CONCLUSION: DT is more accurate than conventional radiography (both AP and axial views) and as accurate as CT in assessing millimeters of displacement of medial epicondyle fracture fragments. LEVEL OF EVIDENCE: Level IV-diagnostic study.

BACKGROUND: Bullying is destructive and pervasive. Although the literature suggests children with chronic health conditions are at higher risk of being bullied, there is minimal research regarding the prevalence of bullying among children with orthopaedic conditions. Our study aimed to assess the prevalence of bullying among pediatric orthopaedic outpatients and evaluate the association of orthopaedic conditions and use of orthopaedic devices with perceptions of bullying. METHODS: Patients in outpatient pediatric orthopaedic clinics, ages 10 to 17 and their parents were surveyed using the Child-Adolescent Bullying Scale-9. Basic demographic, information about the child's orthopaedic condition, and parent's perception of their child being subject to bullying were also collected. Children were asked if they had used any orthopaedic devices in the last 3 months, whether they were bullied because of their device, and if bullying affected their compliance with device use. The analysis utilized a t test or analysis of variance to compare mean Child-Adolescent Bullying Scale-9 scores across different groups. RESULTS: Among the 198 patients surveyed, 61% (N=121) perceived no-to-minimal exposure to bullying, 36% (N=72) moderate exposure, and 3% (N=5) severe exposure. Children ages 10 to 13 (N=100) and children ages 14 to 17 (N=98) reported similar rates of bullying (P=0.97). Higher rates of moderate to severe bullying were reported by patients with foot deformity (80%), multiple orthopaedic diagnoses (55%), chronic pain (39%), fracture/acute injury (37%), and scoliosis (33%). Moderate to severe bullying was reported by 37% of patients who wore a cast, 40% who wore a brace/orthotic, and 52% who used multiple orthopaedic devices. Parental concern that their child was being bullied was highly correlated with their child's bullying score (P=0.0002). CONCLUSIONS: More than one third of our pediatric orthopaedic outpatients (39%) experience moderate to severe levels of bullying, which is higher than the general population's reported rates of 20% to 35%. Exposure to bullying may be higher in certain diagnoses or with use of certain orthopaedic devices. Further research is needed to delineate who is at highest risk. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: The purpose of this study is to identify risk factors associated with repeat surgical irrigation in pediatric septic hip arthritis. METHODS: A single center retrospective case-control study was performed. Patients who underwent ≥2 washouts (cases) were compared with those who had only 1 washout (controls). Demographic, clinical, laboratory, microbial, and magnetic resonance imaging data were compared between cases and controls and a prediction model was developed using logistic regression. A risk score was then constructed by counting the number of risk factors from the model that were present in each patient. RESULTS: We identified 26 patients between 1994 and 2015 who underwent ≥2 washouts for septic hip arthritis, and 63 control patients who had only a single washout. Twenty-two patients had 2 washouts, 3 had 4 washouts, 1 had 5 washouts. Median number of days between first and second washout was 5 (interquartile range, 4 to 8). The most common reason for repeat washout was persistent fever (N=21), followed by persistently elevated laboratory values (N=13), abnormal magnetic resonance imaging findings (N=12), and continued pain (N=12). Repeat washout cases demonstrated higher temperature preoperatively (P<0.001), had more frequent initial misdiagnosis (P=0.002), and had a longer time from symptom onset to surgery (P=0.02). Laboratory values in these cases showed higher C-reactive protein (P=0.003), and more frequent left shift (P=0.03) at presentation, with a greater proportion of positive cultures (P<0.001). Postoperatively, repeat washout cases had higher temperatures (P<0.001), more frequent wound drainage (P=0.02), and complications (P=0.001). A risk score for predicting the likelihood of undergoing repeat washout was constructed by counting the number of the following factors present: presence of left shift in CBC, positive blood or synovial fluid cultures, and postoperative temperature over 39°C. Seventy percent of cases had ≥2 of these risk factors and 80% of controls had ≤1 risk factor. CONCLUSIONS: Cases of pediatric septic arthritis which undergo repeat washout are associated with left shift, high postoperative temperatures, and positive cultures. They have more frequent misdiagnosis leading to delayed treatment and subsequent medical complications. LEVEL OF EVIDENCE: Level III.

OBJECTIVES: Acute exertional compartment syndrome (AECS) is a rare presentation of acute compartment syndrome (ACS) after exertion without injury. Unfamiliarity with this entity can lead to delay in diagnosis. The purpose of this study was to increase awareness of AECS and illustrate the morbidities associated with delayed diagnosis. METHODS: With institutional review board approval, we conducted a retrospective chart review of all patients who underwent emergent fasciotomies for AECS from 1997-2013 at our institution. Male patients with sports-related closed fractures of the tibia leading to ACS were identified for comparison. Demographic variables, patient-specific factors, treatment, and outcome characteristics were analyzed. RESULTS: Seven male patients (mean age, 17 years) presented to our institution with AECS from 1997-2013, and 9 patients with fracture-related ACS were selected for comparison. All cases of AECS occurred in the leg. In the AECS group, the mean time from symptom onset to diagnosis was 97 hours. Four patients initially had a missed diagnosis. On presentation, 6 of 7 patients experienced neurologic symptoms (motor or sensory deficit), although none had perfusion deficits. The mean compartment pressure was 91 mm Hg. They all underwent isolated anterior and lateral compartment releases (except for 1 patient who required a 4-compartment release) and required a mean of 4 surgeries. The mean follow-up was 270 days. Of the 4 patients with missed diagnoses, 2 had significant neurologic and functional deficits at final follow-up. The other 5 patients had a full recovery. Fracture-related ACS patients were younger, with quicker time from symptom onset to surgery, and required more compartments to be decompressed at surgery. CONCLUSIONS: Despite the rarity of AECS, orthopedists as well as primary care, emergency medicine, and sports medicine physicians should maintain a high index of suspicion when examining a patient with leg pain out of proportion to examination after exertion. Delay in diagnosis of AECS is associated with substantial muscle necrosis and morbidity.

Pediatric acute compartment syndrome (PACS) is a clinical entity that must be carefully differentiated from the adult version (ie, acute compartment syndrome). Healthcare providers must understand the variable etiologies of PACS, of which trauma is the most common but can also include vascular insult, infection, surgical positioning, neonatal phenomena, overexertion, and snake and insect bites. In addition to the unique etiologies of PACS, providers must also recognize the different signs and symptoms of PACS. The three As (ie, anxiety, agitation, analgesic requirement) of PACS have supplanted the classic adult signs as being more accurate and allowing earlier detection. In children with questionable clinical signs but concern for PACS, compartment pressure measurement may be necessary to confirm the diagnosis. Overall, outcomes after fasciotomy in children tend to be excellent; however, diagnostic delays secondary to unfamiliar clinical scenarios can lead to myonecrosis and subsequent poor outcomes.

OBJECTIVES: Orthopaedists often speculate how weather and school schedule may influence pediatric orthopedic trauma volume, but few studies have examined this. This study aims to determine: how do weather patterns, day, month, season and public school schedule influence the daily frequency of pediatric orthopedic trauma consults and admissions? METHODS: With IRB approval, orthopedic trauma data from a level 1 pediatric trauma center, including number of daily orthopedic trauma consults and admissions, were collected from July 2009 to March 2012. Historical weather data (high temperatures, precipitation and hours of daylight), along with local public school schedule data were collected for the same time period. Univariate and multivariate regression models were used to show the average number of orthopedic trauma consults and admissions as a function of weather and temporal variables. RESULTS: High temperature, precipitation, month and day of the week significantly affected the number of daily consults and admissions. The number of consults and admissions increased by 1% for each degree increase in temperature (p=0.001 and p<0.001, respectively), and decreased by 21% for each inch of precipitation (p<0.001, p=0.006). Daily consults on snowy days decreased by an additional 16% compared to days with no precipitation. November had the lowest daily consult and admission rate, while September had the highest. Daily consult rate was lowest on Wednesdays and highest on Saturdays. Holiday schedule was not independently significant. CONCLUSION: Pediatric orthopedic trauma consultations and admissions are highly linked to temperature and precipitation, as well as day of the week and time of year.
