The impact on time between injury and semi-acute surgery for hand fractures after virtual fracture clinic implementation

The aim of this before-and-after study was to evaluate the implementation of a virtual fracture clinic (VFC) on the time between injury and surgery in patients presenting with a phalangeal or metacarpal fracture and in need of semi-acute surgical treatment. Between 1 January and 30 September 2018 (pre-VFC) and in the same period in 2022 (VFC), 101 and 113 patients were included, respectively. Before VCF implementation, the time between injury and surgery was 8.9 days (95% confidence interval [CI]: 8.1 to 9.6), while after VCF implementation it was 7.6 days (95% CI: 7.0 to 8.3). In 2018, 7% of operations were unacceptably delayed beyond 14 days from injury, which was reduced to 5% in 2022, despite patient-presentation delays of up to 10 days. VFC implementation was associated with a reduction in time until semi-acute surgery for phalangeal or metacarpal fractures and improved the quality of semi-acute surgery planning.Level of evidence: Level III.

New Injury Patterns in Pediatric Supracondylar Fractures During COVID-19: Beds Are the New Monkey Bars

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.

Surgical site infection in upper extremity fracture: Incidence and prognostic risk factors

Upper extremity fractures (UEF) occurred in about 0.67% of males and females at some point in their lifetime. Surgical treatment has the advantage of good functional recovery, however, the occurrence of surgical site infection (SSI) affects the clinical outcome of operation. Currently, there are few studies focused on SSI of UEF. Consecutive patients with UEF and underwent surgeries from January 2010 to February 2021 were recruited. Demographic data, surgical related variables and laboratory test index of these patients were extracted and collected from the electronic medical records and picture archiving and communication system by well-trained investigators. Receiver operating characteristic (ROC) analysis was performed to detect the optimum cut-off value for continuous variables. Multivariate logistic regression analysis was performed to identify independent risk factors of SSI. In total, 286 patients with a mean age of 44.4 ± 16.6 years were identified for inclusion, 59.8% patients diagnosed with fracture of radius and ulna and 40.2% fractures located in the humerus, closed and open fractures were occurred in 252 and 34 adult patients respectively. 7.3% UEF patients were encountered with SSI, incidence of superficial and deep infection was 6.3% and 1.0%. Open fracture (OR, 8.33; P, .000), operation time longer than 122 minutes (OR, 3.12; P, .036), intraoperative blood loss more than 135 mL (OR, 3.98; P, .009) and albumin (ALB) lower than 40.8 g/L (OR, 3.60; P, .015) were demonstrated as independent risk factors of SSI. Adequate preoperative evaluation, careful intraoperative manipulation, and timely and appropriate postoperative interventions should be formulated to reduce the incidence of SSI in patients with the above perioperative high-risk factors.

Secular trends in incidence and seasonal variation of distal radius fracture among children: A nationwide study based on the Swedish National Patient Register 2002-2016

BACKGROUND AND PURPOSE

Although distal radius fracture (DRF) is the most common fracture type in children, research on its seasonality across different age groups is limited. We investigated secular trends in incidence and seasonal variation of pediatric DRF based on Swedish nationwide population database.

PATIENTS AND METHODS

In this observational study, data for all children aged <18 years in Sweden with DRF defined by ICD-codes were analyzed for each month and each year during 2002-2016 using the Swedish National Patient Register. The general population counts for each age and sex-category were acquired to evaluate population at risk for each period. We calculated the age standardized and sex specific annual incidence rates, seasonal incidence rates, and monthly incidence rates and analyzed the seasonal variation in the mechanisms of injury.

RESULTS

A total of 155,891 DRF cases were identified. The age standardized and sex specific incidence rate was 531 (95%CI 528-533) per 100,000 patient years at risk. Fracture risk was highest during summer and lowest in the winter. The highest seasonal variation was observed among boys 2- < 5 years. The crude incidence rate and the age-standardized incidence rates in winter significantly decreased between 2002 and 2016 (annual percentage change, -2 %).

INTERPRETATION

We found significant seasonal variation in DRF among all age groups in Swedish children. The findings can help in developing strategies to prevent fractures as well as in allocating medical and social resources.

Evaluation of prediction effect of perfusion index for supraclavicular brachial plexus block in children: protocol for a randomized trial

Background

Pulse perfusion index (PI) reflects blood perfusion. It has been reported that PI can be used to evaluate the effect of nerve block, but currently, it is mainly focused on awake adults. In pediatric general anesthesia, it has been reported that PI can evaluate the effect of the sacral block. Still, there is a lack of relevant research on the impact of brachial plexus blocks. Our objective is to assess the prediction effects of PI on the success of supraclavicular brachial plexus block in pediatric patients under sevoflurane or propofol general anesthesia.

Methods/design

This is a mono-center, parallel, 2-arm randomized superiority trial. One hundred four children aged 1 month to 12 years who undergo upper limb surgery will be enrolled in this study. According to anesthesia induction and maintenance medication, they will be divided into sevoflurane and propofol groups. The PI values of the index and little finger will be recorded on the blocked and non-blocked sides of supraclavicular brachial plexus block (SCB) in all children. The primary outcome is to assess the effects of PI on the success of supraclavicular brachial plexus block in pediatric patients under sevoflurane or propofol general anesthesia. The secondary outcome includes mean arterial blood pressure (MAP), heart rate (HR), and correlation between baseline PI and 10 min after SCB (PI ratio).

Discussion

This trial will provide evidence on the changes in PI after SCB in sevoflurane or propofol anesthesia in children. SCB may lead to changes in PI values under sevoflurane or propofol anesthesia. After the children wake up at the end of the surgery, the changes in PI values on the block side and non-block side may be helpful to judge the effect of nerve block when excluding the influence of anesthetics.

Pediatric phalanx fractures: A retrospective study and review of the literature

PURPOSE

Conventional radiography is frequently performed in pediatric patients in whom finger fractures are suspected. However, until now, the rate of positive findings of finger radiographic examinations in pediatric patients is unknown. This study aimed to evaluate the number of positive findings in the standard radiographic examinations of finger injuries in pediatric patients in a Level 1 trauma center systematically.

METHODS

We conducted a retrospective study on all children 0-16 years old admitted for acute finger injury in the Emergency Department of a University Hospital during the first semester of 2019 and received a radiographic examination. Their demographic characteristics, fracture pattern, and treatment were then analyzed and interpreted.

RESULTS

Out of 478 finger injuries reviewed in this cohort, 160 X-rays revealed positive for a fracture giving a fracture rate of 33.5%. More than half of them (51.9%) occurred in the age group of adolescents (11-16 years). Among all finger fractures, only 3.8% of them treated surgically.

CONCLUSION

In this study, a relevant amount of standard finger radiographs revealed a low fracture rate and a rare operative indication of 3.8%. Therefore, indications for X-rays should be reviewed properly and alternative procedures should be discussed. Clinical decision rules should be developed and the necessary pathways must be implemented to minimize radiation exposure, waiting time, and costs.Level of evidence: level IV.

A systematic review of Clinical Practice Guidelines for the management of fractures in children to develop the WHO's Package of Interventions for Rehabilitation

INTRODUCTION

Fractures have been identified as one of the 20 major health conditions for the World Health Organization's (WHO) Package of Interventions for Rehabilitation (PIR) - that includes also the needs of children and youth. The identification of existing interventions for rehabilitation and related evidence is a crucial step along the development of the PIR. The methods for the identification have been developed by WHO Rehabilitation Program and Cochrane Rehabilitation under the guidance of WHO's Guideline Review Committee Secretariat.

EVIDENCE ACQUISITION

This paper is part of the "Best Evidence for Rehabilitation" (be4rehab) series, developed according to the methodology presented in the PIR introductory paper. It is a systematic review of the existing Clinical Practice Guidelines (CPGs) on fractures in pediatric population published between 2009 to 2019.

EVIDENCE SYNTHESIS

We identified seven relevant CPGs after title and abstract screening. According to inclusion/exclusion criteria and after checking for quality, publication time, multidisciplinarity and comprehensiveness, we have been able to include two CPGs: one addresses the treatment of supracondylar humerus fractures and the other provides recommendations on the treatment of diaphyseal femur fractures.

CONCLUSIONS

The selected CPGs on the management of supracondylar humerus and diaphyseal femur fractures in pediatric population include few recommendations considered as interventions for rehabilitation, of low quality of evidence and weak strength. We found several gaps in specific rehabilitative topics. High quality studies are absolutely needed to upgrade the quality of available evidence to inform future development of guidelines.

The increase in paediatric orthopaedic trauma injuries following the end of the curfew during the COVID-19 period

PURPOSE

The aim of this study was to compare the injury patterns of orthopaedic trauma patients in the paediatric age group who presented to our hospital during and after lifting the curfew due to the pandemic, with the patients of the same age group who presented to our institution during the same time period last year.

METHODS

Patients, aged 0 years to 18 years, who presented to our clinic between 21 March 2020 and 31 May 2020 (during curfew) (Group A1, n = 111), between 01 June 2020 and 31 August 2020 (Group A2, n = 214) and during the same periods in 2019 Group B1 (n = 220) and Group B2 (n = 211) were included. Patients with pathological fractures, traumas occurring earlier than the aforementioned date range and those consulted while being hospitalized in another department were excluded from study. Patients' demographics, the department they presented to, the anatomical region affected by trauma, trauma mechanism, the location of trauma, the treatment applied and the length of hospital stay were recorded.

RESULTS

The prevalence of outdoor traumas (72.9% versus 61.1%), high-energy traumas (40.1% versus 26.5%), the rate of the patients treated with surgery (28% versus 17.1%) and the rate of admission to the emergency department (90.2% versus 58.3%) were significantly higher in Group A2 when compared with Group B2 (p < 0.05).

CONCLUSION

The significant increase was observed in the number of outdoor injuries, high-energy traumas and fracture patterns that require surgical treatment during the first three months following the lift of the curfew, in comparison with the corresponding dates from last year. We think that children's lower extremity muscle strength and neuromuscular control was decreased due to staying home for a prolonged period of time.

Diagnostic accuracy of ultrasonography for diagnosis of elbow fractures in children

BACKGROUND

Elbow injuries and fractures are a common pathology in the pediatric emergency unit. X-ray and CT scan of the elbow are the standard diagnostic procedures, which increase exposure to radiation in children. Previous studies have shown that fractures can also be visualized by ultrasound (US); thus, this study aimed to evaluate the diagnostic accuracy of elbow US compared with radiography for the diagnosis of elbow fracture in children.

MATERIALS AND METHODS

This was a prospective observational study of patients aged 2-14 years that presented to emergency departments with a suspected elbow fracture requiring radiographic evaluation. Elbow US for diagnosing elevated posterior fat pad or lipohemarthrosis was performed. All patients underwent elbow radiography and received clinical follow-up. Initial or follow-up X-ray or CT scan was used as the reference standard for fracture diagnosis.

RESULTS

Seventy-five patients with a mean age of 6.51 ± 3.68 years were enrolled in the study. Twenty-eight (37.3%) patients had positive results for fracture. The sensitivity, specificity, and accuracy of US in the diagnosis of elbow fractures were 92.9% (95% CI 76.5-99.1%), 89.4% (95% CI 76.9-96.5%) and 90.7% (95% CI 81.7-96.2%). In patients with fracture, US demonstrated a lipohaemarthrosis in 20 patients (71.4%), elevated posterior fat pad in 19 patients (67.9%), cortical disruption in 10 patients (35.7%), and effusion in three patients (10.7%).

CONCLUSION

Our results showed high diagnostic accuracy for the ultrasonography diagnosis of an elbow fracture, which allows us to confirm ultrasonography imaging of the elbow as a safe alternative in the primary evaluation of pediatric elbow injuries.

Where Have All the Fractures Gone? The Epidemiology of Pediatric Fractures During the COVID-19 Pandemic

BACKGROUND

During the COVID-19 pandemic, public health measures to encourage social distancing have been implemented, including cancellation of school and organized sports. A resulting change in pediatric fracture epidemiology is expected. This study examines the impact of the COVID-19 pandemic on fracture incidence and characteristics.

METHODS

This is a retrospective cohort study comparing acute fractures presenting to a single level I pediatric trauma hospital during the COVID-19 pandemic with fractures during a prepandemic period at the same institution. The "pandemic" cohort was gathered from March 15 to April 15, 2020 and compared with a "prepandemic" cohort from the same time window in 2018 and 2019.

RESULTS

In total, 1745 patients presenting with acute fractures were included. There was a significant decrease in the incidence of fractures presenting to our practice during the pandemic (22.5±9.1/d vs. 9.6±5.1/d, P<0.001). The presenting age for all fractures decreased during the pandemic (7.5±4.3 vs. 9.4±4.4 y, P<0.001) because of decreased fracture burden among adolescents. There were also a decrease in the number of fractures requiring surgery (2.2±1.8/d vs. 0.8±0.8/d, P<0.001). During the pandemic, there was an increase in the proportion of injuries occurring at home (57.8% vs. 32.5%, P<0.001) or on bicycles (18.3% vs. 8.2%, P<0.001), but a decrease in those related to sports (7.2% vs. 26.0%, P<0.001) or playgrounds (5.2% vs. 9.0%, P<0.001). There was no increase in time-to-presentation. Patients with distal radius torus fractures were more likely to receive a velcro splint during the pandemic (44.2% vs. 25.9%, P=0.010).

CONCLUSIONS

Pediatric fracture volume has decreased 2.5-fold during the COVID-19 pandemic, partially because of cessation of organized sports and decreased playground use. In endemic regions, lower trauma volume may allow redeployment of orthopaedic surgeons and staff to other clinical arenas. Given the rising proportion of bicycling injuries, an emphasis on basic safety precautions could improve public health. An observed increase in the prescription of velcro splints for distal radius fractures highlights an opportunity for simplified patient care during the pandemic.
