Minimally angulated pediatric wrist fractures: is immobilization without manipulation enough?

Repurposing Spinal Distractor to Reduce Pediatric Wrist Fractures

Fracture geometry, particularly a jagged bone spike, can present a physical barrier in closed reduction of pediatric distal radius-ulna fractures. When closed reduction of the fracture is not possible, accepting an incomplete reduction and hoping for remodeling, or open reduction, which poses a greater risk for infection and potential physeal injury, are alternative treatment options. The objective of this study was to describe a technique, coined as Percutaneous Skeletal Traction Aided Reduction (P_STAR), for reducing these fractures, thereby eliminating the acceptance of an incomplete reduction and the risks associated with open reduction. In P_STAR, 2 distraction pins are placed 1.5 cm proximal and distal to the fracture site in clearance of the distal radial physis. A shadow-line spinal distractor is then used to distract the pins, reducing the fracture over the irregular impeding fracture geometry. After distraction is released, 1 or 2 K-wires can be percutaneously inserted to transfix the fracture. A video of the technique was also included as Supplemental Digital Content, http://links.lww.com/BTH/A188 . When performed on 18 children with distal radius-ulna fractures, P_STAR achieved near anatomic fracture alignment with no nerve or tendon injury, infection, or refracture.

Robert Jones bandage versus cast in the treatment of distal radius fracture in children: A randomized controlled trial

PURPOSE

The present study aimed to treat fractures of the distal end of the radius in children with Robert Jones (RJ) bandage. The objective was to compare this treatment modality with the cast regarding the frequency of the complication occurrence, child comfortability, and family satisfaction.

METHODS

The study was a randomized controlled non-inferiority clinical trial including children with recent (less than 5 days) fractures at the distal end of the radius OTA/AO 23-A2, which is usually treated conservatively. Those with open fractures, pathological fracture, severely displaced fracture that needs reduction or multiple injuries were excluded. The participants were divided randomly into 2 groups according to the treatment modalities. Group 1 was treated by plaster of Paris cast (control group), and Group 2 by modified RJ bandage (trial group). The difference between 2 groups was found by the Chi-squared test. The difference was considered statistically significant when the p value was less than 0.05.

RESULTS

There were 150 children (aged 2 - 12 years, any gender) included in the study, 75 in each group. The complications occured in 5 (3.3%) cases only, pressure sores in 3 cases treated by the cast and fracture displacement in 2 cases treated by RJ bandage. There was no statistically significant difference in the rate of complication occurrence between both modalities of treatment (p = 0.649). Children treated with RJ bandages were more comfortable than those treated with the cast (97.3% vs. 73.3%, p < 0.001) with a statistically significant difference between them. Contrary to that, the families were more satisfied with the cast than RJ bandage (88.0% vs. 81.3%), but without a statistically significant difference (p = 0.257).

CONCLUSION

RJ bandage is a non-inferior alternative to the cast for the treatment of fractures at the distal end of the radius that can be treated conservatively in children.

Physician self-identified race and opioid prescription practices in upper extremity injuries in the pediatric emergency department

Background

Minority children have been shown to receive fewer opioid analgesics for acute pain.

Objective

Assess if both White and non-White physicians prescribe fewer opioids to non-White children presenting to the pediatric emergency department (PED) with upper extremity (UE) fractures.

Methods

Patients with acute UE fractures were evaluated. Attending physicians provided their self-identified race and consented to analysis of their opioid prescribing practices. Primary outcome was receipt of an opioid prescription at discharge. Bivariate analyses measured the association between patient race and receipt of an opioid prescription; further analysis evaluated the effect of physician race on prescription practices. Generalized linear models measured these associations while controlling for confounders.

Results

Thirty-four percent of eligible patients (2754/8155) were discharged with an opioid prescription. There was no statistically significant difference in odds of being discharged with an opioid prescription for non-Hispanic Black (NHB) compared to non-Hispanic White (NHW) patients. There was no statistically significant difference in odds of prescribing opioids by both White physicians and non-White physicians. In patients with the most severe fractures, requiring sedation for reduction, NHB patients had lower odds of receiving an opioid prescription (OR 0.80; 95% CI: 0.65-0.98).

Conclusion

Within our institution, NHB patients received fewer opioid prescriptions at discharge for UE fractures. There is no statistically significant association between NHB race and odds of receiving an opioid prescription. In patients sedated for fracture reductions, NHB patients had lower odds of receiving an opioid prescription and non-White physicians had lower odds of prescribing opioids to NHB patients compared to NHW patients.

Trends in Management of Pediatric Distal Radius Buckle Fractures

BACKGROUND

Distal radius buckle fractures (DRBFx) represent nearly half of the pediatric wrist injuries. DRBFx are stable injury patterns that can typically be successfully managed with brief immobilization. The purpose of this study was to evaluate opinions and preferences of pediatric orthopaedic specialists regarding the management of DRBFx.

METHODS

The POSNA Trauma Quality, Safety, and Value Initiative (QSVI) Committee developed a 20-question survey regarding the treatment of DRBFx in children. The survey was sent twice to all active and candidate POSNA members in June 2020 (n=1487). Questions focused on various aspects of treatment, including type and length of immobilization, follow-up, and radiographs and on potential concerns regarding patient/family satisfaction and pain control, medicolegal concerns, misdiagnosis, and mismanagement.

RESULTS

A total of 317 participants completed the survey (response rate=21.3%). In all, 69% of all respondents prefer to use a removable wrist splint, with 76% of those in practice <20 years preferring removable wrist splints compared with 51% of those in practice >20 years (χ 2 =21.7; P <0.01). Overall, 85% of participants utilize shared decision-making in discussing management options with patients and their families. The majority of participants felt that the risk of complications associated with DRBFx was very low, but concern for misdiagnosis and mismanagement have required some respondents to perform closed or open reductions.

CONCLUSIONS

In 2020, the majority of respondents treat DRBFx with removable splints (69%) for 3 or fewer weeks (55%), minimal follow-up (85%), and no reimaging (64%). This marks a dramatic shift from the 2012 POSNA survey when only 29% of respondents used removable splinting for DRBFx.

Growth plate injury in children: Review of literature on PubMed

Growth plate injury is a debilitating condition for children. To our knowledge, there is currently no systematic review regarding the complication of epiphyseal injury. Thus, the authors would like to conduct a systematic review regarding this topic. The following strategy was used: the terms used on the PubMed search engine were “growth plate injuries complications.” Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to perform the comprehensive data collection. The initial PubMed search yielded 341 titles and 81 articles included according to the inclusion criteria, but 20 articles were eliminated according to the exclusion criteria. The final total number of articles was 61. The epiphyseal injury usually ends with a good functional outcome, although some serious complication risk remains.

Abbreviated Outpatient Upper Extremity Fracture Care to Avoid Clinic and Hospital Environmental Encounters During the COVID-19 Pandemic: A New Approach to Fracture Care?

BACKGROUND

To minimize in-person visits during the COVID-19 pandemic, a new fracture care protocol for children with complete and stable, nondisplaced or minimally displaced upper extremity (UE) fractures has been implemented. This protocol involves immobilization with a bivalved cast, which allows for home cast removal during a telemedicine visit, and no follow-up radiographs, thus eliminating the requirement for a return to clinic. The purpose of this study is to evaluate the outcomes and parent satisfaction of this new abbreviated fracture care protocol.

METHODS

Between May 2020 and April 2021, during the COVID-19 pandemic, children with complete and stable, nondisplaced or minimally displaced UE fractures were treated with a bivalved cast and 1 follow-up telemedicine visit for home cast removal. A prospective longitudinal study of these patients was performed. The PROMIS Upper Extremity questionnaire was administered at enrollment and 3 months follow-up. Parents completed a satisfaction survey after home cast removal. Demographic data and information regarding complications were collected. A historical cohort of controls treated with standard cast in 2019 was used for comparison.

RESULTS

A total of 56 patients with a mean age of 8±3 years (range 2 to 15) were prospectively enrolled in this study. Parent-reported PROMIS Upper Extremity scores showed a significant increase from 24.9 (95% confidence interval=20.8-29.1) at enrollment to 51.6 (95% confidence interval=50.8-52.5) at 3 months follow-up (P<0.001). Results of the satisfaction survey (n=39) showed all parents were either very satisfied (85%) or satisfied (15%). In addition, 10% of parents would have initially preferred to come into clinic for cast removal and 90% of parents would prefer this new treatment plan in the future. Patients in the abbreviated care cohort returned to clinic for a median 1 in-person visits, compared with 2 for historical controls (n=183, P<0.001). Abbreviated care patients received fewer (1.0) radiographs than controls (2.0, P<0.001). Complication rate did not differ between the groups (P=0.77).

CONCLUSIONS

Complete and stable, nonminimally or minimally displaced UE fractures can be cared for safely and effectively in a single in-person visit, with a telemedicine cast removal visit. Parents are satisfied with this abbreviated protocol and prefer it to additional in-person visits.

Factors affecting management of children's low-risk distal radius fractures in the emergency department: a population-based retrospective cohort study

BACKGROUND

Ten randomized controlled trials over the last 2 decades support treating low-risk pediatric distal radius fractures with removable immobilization and without physician follow-up. We aimed to determine the proportion of these fractures being treated without physician follow-up and to determine whether different hospital and physician types are treating these injuries differently.

METHODS

We conducted a retrospective population-based cohort study using ICES data. We included children aged 2-14 years (2-12 yr for girls and 2-14 yr for boys) with distal radius fractures having had no reduction or operation within a 6-week period, and who received treatment in Ontario emergency departments from 2003 to 2015. Proportions of patients receiving orthopedic, primary care and no follow-up were determined. Multivariable log-binomial regression was used to quantify associations between hospital and physician type and management.

RESULTS

We analyzed 70 801 fractures. A total of 20.8% (n = 14 742) fractures were treated without physician follow-up, with the proportion of physician follow-up consistent across all years of the study. Treatment in a small hospital emergency department (risk ratio [RR] 1.86, 95% confidence interval [CI] 1.72-2.01), treatment by a pediatrician (RR 1.22, 95% CI 1.11-1.34) or treatment by a subspecialty pediatric emergency medicine-trained physician (RR 1.73, 95% CI 1.56-1.92) were most likely to result in no follow-up.

INTERPRETATION

While small hospital emergency departments, pediatricians and pediatric emergency medicine specialists were most likely to manage low-risk distal radius fractures without follow-up, the majority of these fractures in Ontario were not managed according to the latest research evidence. Canadian guidelines are required to improve care of these fractures and to reduce the substantial overutilization of physician resources we observed.

Developing a core outcome set for paediatric wrist fractures: a systematic review of prior outcomes

Objectives

This review aims to summarize the outcomes used to describe effectiveness of treatments for paediatric wrist fractures within existing literature.

Method

We searched the Cochrane Library, Scopus, and Ovid Medline for studies pertaining to paediatric wrist fractures. Three authors independently identified and reviewed eligible studies. This resulted in a list of outcome domains and outcomes measures used within clinical research. Outcomes were mapped onto domains defined by the COMET collaborative.

Results

Our search terms identified 4,262 different papers. Screening of titles excluded 2,975, leaving 1,287 papers to be assessed for eligibility. Of this 1,287, 30 studies were included for full analysis. Overall, five outcome domains, 16 outcome measures, and 28 measurement instruments were identified as outcomes within these studies. 24 studies used at least one measurement pertaining to the physiological/clinical outcome domain. The technical, life impact, and adverse effect domains were recorded in 23, 20, and 11 of the studies respectively. Within each domain it was common for different measurement instruments to be used to assess each outcome measure. The most commonly reported outcome measures were range of movement, a broad array of “radiological measures” and pain intensity, which were used in 24, 23, and 12 of the 30 studies.

Conclusion

This study highlights the heterogeneity in outcomes reported within clinical effectiveness studies of paediatric wrist fractures. We provided an overview of the types of outcomes reported in paediatric wrist fracture studies and identified a list of potentially relevant outcomes required for the development of a core outcome set.

Displaced Physeal and Metaphyseal Fractures of Distal Radius in Children. Can Wire Fixation Achieve Better Outcome at Skeletal Maturity than Cast Alone?

Introduction

Redisplacement following fracture reduction is a known sequela during the casting period in children treated for distal radius fracture. Kirschner wire pinning can be alternatively used to maintain the reduction during fracture healing. This study was conducted to compare the outcomes at skeletal maturity of distal radius fractures in children treated with a cast alone or together with a Kirschner wire transfixation.

Material and Methods

This was a retrospective study involving 57 children with metaphyseal and physeal fractures of the distal radius. There were 30 patients with metaphyseal fractures, 19 were casted, and 11 were wire transfixed. There were 27 patients with physeal fractures, 19 were treated with a cast alone, and the remaining eight underwent pinning with Kirschner wires. All were evaluated clinically, and radiologically, and their overall outcome assessed according to the scoring system, at or after skeletal maturity, at the mean follow-up of 6.5 years (3.0 to 9.0 years).

Results

In the metaphysis group, patients treated with wire fixation had a restriction in wrist palmar flexion (p=0.04) compared with patients treated with a cast. There was no radiological difference between cast and wire fixation in the metaphysis group. In the physis group, restriction of motion was found in both dorsiflexion (p=0.04) and palmar flexion (p=0.01) in patients treated with wire fixation. There was a statistically significant difference in radial inclination (p=0.01) and dorsal tilt (p=0.03) between cast and wire fixation in physis group with a more increased radial inclination in wire fixation and a more dorsal tilt in patients treated with a cast. All patients were pain-free except one (5.3%) in the physis group who had only mild pain. Overall outcomes at skeletal maturity were excellent and good in all patients. Grip strength showed no statistical difference in all groups. Complications of wire fixation included radial physeal arrests, pin site infection and numbness.

Conclusion

Cast and wire fixation showed excellent and good outcomes at skeletal maturity in children with previous distal radius fracture involving both metaphysis and physis. We would recommend that children who are still having at least two years of growth remaining be treated with a cast alone following a reduction unless there is a persistent unacceptable reduction warranting a wire fixation. The site of the fracture and the type of treatment have no influence on the grip strength at skeletal maturity.

Closed reduction of paediatric forearm fractures: nitrous oxide versus general anaesthetic

BACKGROUND

Nitrous oxide with intranasal fentanyl is safe and effective in performing closed reduction of paediatric forearm fractures; however, the difference in outcome when compared to those performed under general anaesthesia (GA) is unclear. We aim to compare the outcomes of closed reduction of paediatric forearm fractures under nitrous oxide versus GA.

METHODS

This retrospective study based on a prospective change in protocol reviewed the medical records and radiographs of patients with forearm fractures who presented to a tertiary paediatric centre, and who subsequently underwent closed reduction under either nitrous or GA. Data on patient demographics, type and site of fracture and the method of casting were collected. The primary outcomes were loss of reduction, the need for repeat intervention and the rate of complications.

RESULTS

There were 301 and 362 patients in the nitrous and GA groups respectively. The overall re-intervention rate was 7.6% in the nitrous group versus 5.0% in the GA group (P = 0.155). There was no significant difference in loss of reduction which involved 9.0% in the nitrous group and 11.3% in the GA group (P = 0.320). There was no significance difference in overall complications. Nausea and vomiting comprised the majority of adverse events.

CONCLUSION

Closed reduction of paediatric forearm fractures performed under nitrous oxide with intranasal fentanyl is safe, effective and achieves comparable re-intervention rates and adverse events to those performed under GA in the operating theatre.

Resource Utilization for Patients With Distal Radius Fractures in a Pediatric Emergency Department

IMPORTANCE

Improvement of clinician understanding of acceptable deformity in pediatric distal radius fractures is needed.

OBJECTIVE

To assess how often children younger than 10 years undergo a potentially unnecessary closed reduction using procedural sedation in the emergency department for distal radial metaphyseal fracture and the associated cost implications for these reduction procedures.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cross-sectional study included 258 consecutive children younger than 10 years who presented to a single, level I, pediatric emergency department and who had a distal radius fracture with or without ulna involvement between January 1, 2016, and December 31, 2017. Reductions were deemed to be potentially unnecessary if the coronal and sagittal plane angulation of the radius bone measured less than 20° and shortening measured less than 1 cm on initial injury radiographs. Use of procedural sedation or transfer status to another facility was noted if present. Statistical analysis was performed from April 2019 to June 2019.

MAIN OUTCOMES AND MEASURES

Potentially unnecessary reduction was the primary outcome. Radiographic findings were measured to determine reduction necessity. Additional variables measured were age, sex, time in the emergency department, transfer status, required reduction procedure, use of sedation, and cost associated with care.

RESULTS

Of the 258 participants studied, 156 (60%) were male, with a mean (SD) age of 6.7 (2.3) years. Among 142 patients (55%) who underwent closed reduction with procedural sedation in the emergency department, 38 (27%) procedures were determined to be potentially unnecessary. Review of Common Procedural Terminology charges revealed an approximately $7000 difference between the stated cost of a reduction procedure in the emergency department vs a cast application in an outpatient orthopedic clinic for distal radial metaphyseal fractures. The mean (SD) maximal angulation in either plane for fractures that underwent appropriate reduction was 30.6° (10.3°) compared with 13.9° (4.5°) for those unnecessarily reduced (P < .001). Patients who were transfers from other facilities were more than twice as likely to undergo a potentially unnecessary reduction (odds ratio, 2.3; 95% CI, 1.1-5.0; P = .03).

CONCLUSIONS AND RELEVANCE

The findings suggest that improved awareness of these acceptable deformities in young children may be associated with limiting the number of children requiring reduction with sedation, improving emergency department efficiency, and substantially reducing health care costs.

Success Rates for Reduction of Pediatric Distal Radius and Ulna Fractures by Emergency Physicians

BACKGROUND

Emergency physicians are trained in urgent fracture reduction. Many hospitals lack readily available in-house orthopedic coverage.

OBJECTIVES

The aim of this study was to determine success rates for reduction of pediatric distal radius or ulna fractures by emergency department (ED) physicians.

METHODS

We conducted a retrospective study of children younger than 18 years presenting to a large, urban, freestanding children's hospital from January 1, 2009, to December 31, 2010, with forearm fracture. Exclusions included open fracture, those requiring immediate surgical intervention, or additional fractures. The primary end point was the proportion of successful closed forearm fracture reductions in the ED, as defined by orthopedic follow-up.

RESULTS

All reductions were performed by a board-certified/eligible pediatric emergency medicine (PEM) physician or PEM fellow. Two hundred ninety-five fractures were reduced in the ED during the study period. Mean age was 8.27 years (median, 8 years; range, 1-16 years), and males comprised 69.2% (n = 204). A total of 222 fractures (76%) were of the distal forearm, and 70 involved the midshaft (24%). Orthopedic follow-up was completed in 77.3%. A total of 33 patients (11%) required remanipulation; 24 in the distal forearm fracture group (22 closed reductions, 2 open reductions with internal fixation) versus 9 in the midshaft group (7 closed reductions, 2 open reductions with internal fixation) (P = 0.948).

CONCLUSIONS

The literature reveals 7% to 39% of children with fracture reductions performed in the ED by orthopedic surgeons/residents require remanipulation. Our rate of 11% is consistent within that range. With training, PEM physicians have similar success rates as orthopedists in forearm fracture reductions.

The Emergency Evaluation and Management of Pediatric Extremity Fractures

Approximately one-third of children sustain a fracture before the age of 16 years; however, their unique anatomy and healing properties often result in a good outcome. This article focuses on the diagnosis and management of pediatric extremity injuries. The article describes the anatomic features and healing principles unique to children and discusses pediatric upper and lower extremity fractures and presents evidence-based and standard practice for their management. Finally, the article describes the conditions under which emergency physicians are likely to miss pediatric fractures by highlighting specific examples and discussing the general factors that lead to these errors.

Efficacy, pain, and overall patient satisfaction with pediatric upper arm fracture reduction in the emergency department

INTRODUCTION

Immediate closed reduction and cast immobilization performed under sedation in the emergency room is the mainstay management for most isolated displaced or angulated upper limb fractures in children. We aimed to determine if this approach is safe, effective and if patients, parents and staff are satisfied with this approach.Our working hypothesis was this management provides a high satisfaction rate.

PATIENTS AND METHODS

Between January 2017 and October 2017 we included 118 children presenting with upper arm fractures amenable to closed reduction under our institutional analgesia protocol. Children received 0.4mg/kg of Oramorph oral solution, they were then evaluated 40minutes later, and if their Face Legs Activity Cry Consolability (for children under 16 years-old) and/or Visual Analog Scale (for children over 6 years-old) were under 4, they underwent closed reduction by an orthopaedic resident under Nitrous oxide. If their pain assessment scale was above 4, they received an extra 0.4mg/kg of Oramorph oral solution and underwent closed reduction 40minutes later under nitrous oxide. These children were managed without hospitalization, as outpatients. Children>6, families and nursing staff were also given a visual satisfaction scale (using a 1-10 score) just before being discharged from the ER in order to evaluate their experience.

RESULTS

Closed reduction in the ER was judged satisfactory from an orthopedic point-of-view in 115 cases (97.6%). Parents, children and the nursing team gave the experience in the ER an average satisfaction score of 9 out of 10.

CONCLUSION

ER reduction is not only safe and effective but is also associated with a high satisfaction rate amongst children, their families and the nursing staff.

A Bundled Payment Model for Pediatric Distal Radius Fractures: Defining an Episode of Care

BACKGROUND

Distal radius fractures are the most common fracture of childhood, occurring in ∼1 per 100 children annually. Given the high incidence of these fractures, we explored feasibility of a bundled payment model. We determined the total treatment costs for each child and identified components of fracture management that contributed to variations in cost.

METHODS

We retrospectively reviewed all hospital and physician costs related to the treatment of closed distal radius fractures at a large academic children's hospital. We included all children age 2 to 15 years treated by an orthopaedic surgeon for an isolated closed distal radius fracture between 2013 and 2015. We compared total treatment costs by fracture management approach. We then estimated the contribution of each component of fracture management to total treatment costs using linear regression.

RESULTS

We identified 5640 children meeting the inclusion criteria, of which 4602 (81.6%) received closed treatment without manipulation, 922 (16.3%) underwent closed reduction in the clinic, emergency department, or radiology procedure suite, and 116 (2.1%) underwent treatment in the operating room. The median cost for closed treatment without manipulation was $1390 [interquartile range (IQR) 1029 to 1801], compared with $4263 (IQR, 3740 to 4832) for closed reduction and $9389 (IQR, 8272 to 11,119) for closed reduction and percutaneous pinning (P<0.001). In multivariable regression analysis, fracture management approach and use of the operating room environment were the largest cost drivers (P<0.001, R=0.88). Closed reduction in the clinic or emergency department added $894 (95% confidence interval, 819-969) to treatment costs, while closed reduction in the operating room added $5568 (95% confidence interval, 5224-6297). Location of the initial clinical evaluation, number of radiographic imaging series obtained, and number of orthopaedic clinic visits also contributed to total costs.

CONCLUSIONS

Closed pediatric distal radius fractures treated without manipulation show small variations in treatment costs, making them well suited for bundled payment. Bundled payments for these fractures could reduce costs by encouraging adoption of existing evidence-based practices.

Cost savings of implementing the SickKids Paediatric Orthopaedic Pathway for proximal humerus fractures in Ontario, Canada

Background

The SickKids Paediatric Orthopaedic Pathway (SKPOP) for proximal humerus fractures may safely reduce the number of radiographs and follow-up assessments for children with these injuries. The study objective was to examine potential cost-savings of the SKPOP from the perspective of the Ministry of Health and Long-term Care (MOHLTC).

Methods

Two sets of resource profiles, based on direct health care costs were created for a cohort of patients treated at our institution: the first based on actual follow-up assessment values, and the other based on follow-up assessments according to the SKPOP. Differences between the two profiles represent potential cost-savings. A decision-analysis and associated probabilistic sensitivity analysis (PSA) were performed.

Results

In a cohort of 239 patients treated between 2009 and 2014, 92.9% (222) would have met SKPOP eligibility. Management according to this pathway would have reduced orthopaedic assessments and shoulder radiograph series by 83.6% (470/562) and 70.8% (367/589), respectively. For the cohort examined, a potential cost-savings of $30,040.56 ($135.32/patient) was observed. A PSA, accounting for variable SKPOP adherence and health care utilization, yielded cost-savings in 96.5% of the iterations run through the decision-analysis model and an average cost-savings of $57.82/patient. Based on these results and the annual provincial incidence rate of eligible patients (n=575), the MOHLTC could potentially save $33,249.45 annually with province-wide implementation.

Conclusions

Implementation of the SKPOP for a cohort of patients managed at our institution could have resulted in cost-savings due to substantial reductions in health care utilization. Cost-savings are likely to occur with provincial implementation of the SKPOP for proximal humerus fractures.

Patterns of paediatric forearm fractures at a level I trauma centre in KSA

Objectives

The current literature does not clearly elaborate the pattern of paediatric forearm fractures. This study aims to identify patterns of paediatric forearm fractures in KSA.

Methods

This retrospective study was conducted in a level I trauma centre. The study population comprised patients up to 18 years of age who presented with forearm fractures between 2007 and 2015. The demographic data of the recruited patients were obtained from medical files, and fractures were identified using plain films. Mean and standard deviations were used for continuous variables, whereas frequencies and percentages were used for categorical variables.

Results

This study included 318 patients, ranging in age from 1.2 to 18 years (average: 10.42 ± 4.56 years). The majority were boys (80.8%) and 53.1% were <12 years of age. Girls were significantly more prevalent in the <12-year-old group than in the ≥12-year-old group (p < 0.001). A fall was the mechanism of injury in the majority of patients (82.1%) in the <12-year-old group compared with the ≥12-year-old group (p < 0.001). There was no statistically significant difference in fracture site between the two age groups. The distal forearm was the most common site fractured (47.8%), followed by the distal third of the forearm diaphysis (34.2%).

Conclusion

Forearm fractures are commonly seen in school-age boys. The distal radius is the most commonly fractured site reported in this study. A fall was the most common mechanism of injury, and safety measures should be implemented in places where children frequently gather.

•

The distal radius is the most common fracture site.

•

A fall was the most common mechanism of injury in our population.

•

Fractures of the forearm occur more commonly in boys.

It is not just comfort: waterproof casting increases physical functioning in children with minimally angulated distal radius fractures

Waterproof casting has been reported to increase patient comfort and satisfaction, and decrease skin irritation. There are no available data on the influence of waterproof casting materials on physical function in pediatric patients. Our aim was to determine whether the use of waterproof casting would result in faster recovery of physical function while maintaining similar clinical outcomes as those obtained with nonwaterproof materials. Twenty-six children with nonangulated or minimally angulated distal radius fractures were assigned randomly to initially receive a short-arm cast made of one of two optional materials: a hybrid mesh material with a waterproof lining or fiberglass with a nonwaterproof skin protector. Two weeks later, the initial cast was removed and replaced with a short-arm cast made of the alternative option. We compared the rate of fracture displacement, physical function, pain, skin changes, itchiness, and patient satisfaction. No evidence of displacement was found in either group. The mean Activities Scale for Kids - Performance (ASK-P) (physical function) score was 10% higher during the period of time when a waterproof cast was used (P=0.04). When a waterproof cast was used during the first 2 weeks of treatment, the mean total ASK-P scores were 23% higher than that when a nonwaterproof one was used during the same period of time (P=0.003). Patients who received a waterproof cast as the initial treatment reported lower functional scores overall and in almost every domain of the ASK-P once they were in a nonwaterproof one; similarly, those who received a nonwaterproof cast as the initial treatment reported higher functional scores overall and in every domain of the ASK-P once they were in a waterproof cast. Compared with a nonwaterproof cast, the use of waterproof casting resulted in comparable levels of pain, itchiness, skin irritability, and overall patient satisfaction. The results of this randomized, cross-over trial suggest that the use of waterproof casting material for the treatment of nondisplaced or minimally displaced distal radius fractures in children can result in a faster recovery of physical function, while providing comparable stability, pain, itchiness, skin irritability, and overall patient satisfaction.

Nationwide survey on current management strategies of toddler's fractures

BACKGROUND

Tibial fractures are common in children less than 3 years old. The traditional management involves immobilization in an above knee cast for both confirmed (positive x-ray) and presumed (normal x-ray) toddler's fractures. This carries health care implications and causes unnecessary burden for patients and their families. There is a paucity of literature describing the ideal immobilization strategy for this injury.

OBJECTIVES

To determine: 1) the variation between Canadian emergency departments in management of toddler's fractures; 2) the variation in management between confirmed and presumed toddler's fractures; 3) the association between demographic variables and immobilization strategies.

METHODS

This was an email survey of all members of the Pediatric Emergency Research Canada network. The survey consisted of 2 clinical vignettes followed by multiple-choice questions.

RESULTS

Survey response rate was 73% (153/211). For confirmed toddler's fractures, 39% of physicians chose to immobilize with above knee circumferential cast, 27% with below knee circumferential cast and 20% with below knee splint. For presumed toddler's fractures, 44% of respondents chose to manage without casting, 22% with below knee splint and 14% with above knee circumferential cast. There was significant practice variation between Canadian pediatric emergency departments for both types of fractures and between the management of confirmed and presumed toddler's fractures.

CONCLUSIONS

Our study is the first to identify nationwide variation in the management of toddler's fractures. This variation highlights the need for future research to compare the different management strategies to determine families' preferences and functional outcomes in children with these injuries.

A percutaneous reduction technique for irreducible and difficult variant of paediatric distal radius and ulna fractures

BACKGROUND AND AIM

The objective of this study is to introduce a novel percutaneous reduction technique for irreducible and difficult paediatric radius and ulna fractures in the distal forearm.

METHODS

From May 2010 to January 2012, the percutaneous joystick technique was conducted in 48 children who sustained irreducible or difficult radius and ulna fractures in the distal forearm. The series comprises 32 male and 16 female patients with an average age of 11 years (range, 7-15 years). Among them, 22 patients were <9 years of age. At the final follow-up, the range of motion of the wrist and grip strength of the hand were assessed. Measurements were compared to those on the opposite side. Wrist function was assessed with Mayo Wrist Score. Appearance and patient satisfaction were assessed using the 10-cm visual analogue scale. A p-value <0.05 was considered statistically significant.

RESULTS

Bone healing was achieved in all patients (radius: mean 3.5 weeks, range, 3-4 weeks; ulna: 3.8 weeks, range, 3-4 weeks), respectively. After an average follow-up period of 39 months (range, 36-45 months), patients had an average range of wrist motion of 74° (range, 65-86°) in flexion and 64° (range, 54-78°) in extension. The mean grip strength of the injured side was 33.7kg (13.8-47.6kg). The mean Mayo Wrist Score was 97 (range, 85-100), including 44 excellent and four good results. The mean scores of appearance and patient satisfaction on the forearm were 9.7 (range, 9-10) and 9.8 (range, 8-10), respectively. No significant difference was found regarding the range of motion and grip strength (p<0.05).

CONCLUSIONS

The percutaneous reduction technique is a safe and valuable procedure for irreducible and difficult paediatric fractures of distal radius and ulna.

Salter-Harris type-IV displaced distal radius fracture in a 5-year-old

Displaced Salter-Harris type-IV fractures are rare in young children and can result in articular incongruity or premature physeal arrest. We describe a 5-year-old boy who sustained a displaced left distal radial Salter-Harris type-IV fracture. The patient had normal wrist function and physeal growth at the 3-year postoperative follow-up. Our patient is by far the youngest reported child with a displaced Salter-Harris type-IV fracture of the distal radius. Prompt anatomic reduction and fixation of a displaced distal radial Salter-Harris type-IV fracture can result in excellent short-term wrist motion with maintenance of physeal function.

A structured review addressing the use of radiographic measures of alignment and the definition of acceptability in patients with distal radius fractures

BACKGROUND

Standard radiographs are routinely used in clinical care to characterize the severity of a distal radius fracture and to monitor patients following a distal radius fracture. The objective of this review was to describe the range and variability of radiographic measures described in the literature in patients following a distal radius fracture.

METHODS

A structured literature review was conducted using the Embase and PubMed databases. Inclusion criteria included full-text publications which employed radiographic measures to examine 100 or more participants following a distal radius fracture. A standardized data extraction form was used to identify study design, fracture classification systems, the types of and definitions of radiographic measurements, and acceptability criteria following distal radius fractures.

RESULTS

From an initial 263 studies, 31 studies were included in the final data extraction process. A narrative synthesis of the articles included in this review indicated that there was a set of commonly used radiographic measurements examined in patients with a distal radius fracture which included radial inclination, volar/dorsal tilt, intra-articular step/gap, and a measure of ulnar variance/radial shortening. While 52 % of studies referenced or published a standardized measurement technique, there was substantial variability in the actual description of each radiographic measurement performed.

CONCLUSIONS

Substantial variability in how radiographic measurements are defined in large clinical studies as seen in this review suggest a need for consensus on the assessment and interpretations of radiographic measures used in patients following a distal radius fracture. Guidelines for radiographic measures should be established to ensure consistency between research and treatment centers.

A comparison of intervention and conservative treatment for angulated fractures of the distal forearm in children (AFIC): study protocol for a randomized controlled trial

Background

Angulated fractures of the distal forearm are very frequent lesions in childhood. Currently, there are no standard guidelines on whether these children should be treated conservatively with a cast; with reduction and a cast; or with reduction, pinning and a cast under anesthesia.

Minor prospective and retrospective studies have shown that the distal physis of the forearm possesses high remodeling capacity leading to reliable correction of malalignment.

The aim of this trial is to answer the question about whether operative and conservative treatment show equivocal results.

Methods/Design

This is a prospective, multinational, multicenter, randomized, observer-blinded, actively controlled, parallel group trial, with 24 months of observation.

The primary objective of this trial is to assess whether or not the long-term functional outcome in remodeling patients is inferior to patients receiving closed reduction and K-wire pinning.

The trial should include 742 patients with acute fracture. The patients will be included in 30 medical centers in Germany, Switzerland and Austria.

All patients 5 to 11 years of age presenting at the emergency department with an angulated distal fracture of the forearm will be randomized online after informed consent.

The primary endpoint is the Cooney Score after 24 months. The secondary endpoint is the grade of radiological displacement at 12/24 months.

Discussion

Therapy of angulated fractures is a matter of intensive debate. Primary manipulation and pinning under general anesthesia is recommended in order to avoid malalignment. No major study has proven the advantage of manipulation and pinning over immobilization alone. Should remodeling appear to be a safe alternative, manipulation under general anesthesia, K-wire pinning and removal of pins could be avoided, thus sparing significant costs.

Variation in practice habits in the treatment of pediatric distal radius fractures

Distal radius fractures are widespread in the pediatric population. Standardized treatment protocols have not been well defined. We sought to examine the diversity of current practice patterns in the treatment of these fractures by surveying hand, pediatric, and general orthopedic surgeons. Hand, pediatric, and general orthopedic surgeons were surveyed using an internet-based questionnaire on the management of pediatric distal radius fractures. Each surgeon was asked to select a criterion from among choices of 'acceptable' alignment criteria at the onset of the survey. Ten cases were then provided to represent a broad spectrum of injuries from minimally angulated torus fractures to complete, displaced fractures. In addition to the variation in injury pattern, the patients in the survey differed in age at the time of injury (3-15 years of age). For each case, surgeons were asked to select a preferred treatment, first on the basis of injury films, and then again after reviewing 1-week follow-up radiographs. A total of 781 surgeons completed the survey. In patients younger than 9 years of age, a residual sagittal angulation of 20° or less, coronal angulation of 10° or less, and 1 cm or less of bayonet apposition was deemed 'acceptable' by 88, 90, and 69% of respondents, respectively. In older patients, these percentages were 58, 64, and 29%, respectively. When specific cases were reviewed, 20.3% of surgeons recommended treatment different from their own theoretical 'acceptable' criteria. When subspecialty training was analyzed, hand surgeons and general orthopedic surgeons were 2.9 and 1.6 times more likely to recommend surgery, respectively, as compared with pediatric surgeons after viewing the initial radiograph. Private practice surgeons were 1.5 times more likely to recommend surgery compared with academic surgeons based on the initial injury radiographs. Our survey highlights the discordance between theoretical acceptable criteria of surgeons and their practice habits, as well as the substantial disparities in treatment recommendations based on subspecialty training. Further study is warranted to determine whether these variations in treatment affect patient outcomes. This survey is a level IV observational study.

Think twice before re-manipulating distal metaphyseal forearm fractures in children

BACKGROUND

Treatment of displaced paediatric distal forearm fractures is not always successful. Re-occurrence of angular deformity is a frequent complication. No consensus exists when to perform secondary manipulations. The purpose of this study was to analyse the long-term outcome of re-angulated paediatric forearm fractures to determine if re-manipulations can be avoided.

METHODS

Children who underwent closed reduction for distal forearm fractures and presented with re-angulation at follow-up were included in this retrospective cohort study. We compared those that were re-manipulated to those managed conservatively. Re-angulation was defined as ≥15° of angulation on either the AP or lateral view. Children were reviewed after 1-8 years post injury. Outcome measures were residual angulation on radiographs, active range of motion, grip strength, Visual Analogue Scales (satisfaction, cosmetics and pain) and the ABILHANDS-kids questionnaire.

RESULTS

Sixty-six children (mean age of 9.6 years) were included. Twenty-four fractures were re-manipulated and 42 fractures had been left to heal in angulated position. At time of re-angulation, children <12 years in the conservative group had similar angulations to those re-manipulated. Children ≥12 years in the re-manipulation group had significantly greater angulations than children in the conservative group. At final follow-up, after a mean of 4.0 years, near anatomical alignment was seen on radiographs in all patients. Functional outcome was predominantly excellent. There was no significant difference in functional, subjective or radiological outcomes between treatment groups.

CONCLUSION

Re-manipulation of distal forearm fractures in children <12 years did not improve outcomes, deeming re-manipulations unnecessary. Children ≥12 years in the conservative group achieved satisfactory outcomes despite re-angulations exceeding current guidelines. Based on observed remodelling, we now accept up to 30° angulation in children <9 years; 25° angulation in children aged 9-<12; 20° angulation in children ≥12 years, when re-angulation occurs. We conclude that clinicians should be more reluctant to perform re-manipulations.

Pediatric upper-extremity fractures

Upper-extremity fractures account for more than half of childhood bony injuries. The frequency of injury increases with increasing mobility. The most common mechanism is a fall on an outstretched hand while playing. Optimal management requires knowledge of the normal anatomy and variants unique to pediatric bones. The physician needs to maintain a high level of suspicion for growth plate injuries because if unrecognized, these may result in growth arrest. Although the vast majority of pediatric upper-extremity fractures will heal rapidly with minimal intervention, physicians should be aware of the complications that can arise from these injuries.

The epidemiology of distal radius fractures

Distal radius fractures are one of the most common types of fractures. Although the pediatric and elderly populations are at greatest risk for this injury, distal radius fractures still have a significant impact on the health and well-being of young adults. Data from the past 40 years have documented a trend toward an overall increase in the prevalence of this injury in both the pediatric and elderly populations. Understanding the epidemiology of this fracture is an important step toward the improvement of treatment strategies and the development of preventive measures with which to target this debilitating injury.

Cost-effectiveness analysis of cast versus splint in children with acceptably angulated wrist fractures

OBJECTIVES

In a practice setting where casting is considered the standard of care, the aim of this study was to assess the cost-effectiveness of wrist splints compared with routine casting in children with acceptably angulated distal radius greenstick or transverse fractures.

METHODS

A cost-effectiveness analysis was conducted alongside a randomized controlled trial (RCT). One hundred children with acceptably angulated distal radius greenstick or transverse fractures received either a wrist splint or cast. Information on health care provider and patient and family resource use as well as productivity cost was collected. Resource use was costed using unit costs from local administrative data sources and expense diaries. Effectiveness was assessed at 6 weeks using the performance version of the Activities Scale for Kids (ASKp) questionnaire. Cost-effectiveness analysis related differential costs to differential ASKp scores.

RESULTS

Mean total cost was $877.58 in the splint group and $950.35 in the cast group, with a mean difference of $-72.76 (standard error [SE] 45.88). Mean total healthcare cost was $670.66 in the splint group and $768.22 in the cast group, with a mean difference of $-97.56 (SE 9.24). Mean (SE) ASKp was 92.8 in the splint group and 91.4 in the cast group, with a mean difference of 1.439 (SE 1.585). Therefore, splint management was more effective and cheaper. After accounting for uncertainty, the probability of splint being cost-effective compared with cast was 94 percent for a willingness-to-pay threshold value of $0 for one-unit gain in ASKp score and exceeded 82 percent for all threshold values.

CONCLUSIONS

In this RCT, splint management was cost-effective compared with casting in children with acceptably angulated distal radius greenstick or transverse fractures. This study challenges the existing standard of care for children with this type of fracture and provides justification on clinical and economic grounds for a change in routine practice.

Cast versus splint in children with minimally angulated fractures of the distal radius: a randomized controlled trial

BACKGROUND

Minimally angulated fractures of the distal radius are common in children and have excellent outcomes. We conducted a randomized controlled trial to determine whether the use of a prefabricated splint is as effective as a cast in the recovery of physical function.

METHODS

We included 96 children 5 to 12 years of age who were treated for a minimally angulated (≤ 15°) greenstick or transverse fracture of the wrist between April 2007 and September 2009 at a tertiary care pediatric hospital. Participants were randomly assigned to receive either a prefabricated wrist splint or a short arm cast for four weeks. The primary outcome was physical function at six weeks, measured using the performance version of the Activities Scale for Kids. Additional outcomes included the degree of angulation, range of motion, grip strength and complications.

RESULTS

Of the 96 children, 46 received a splint and 50 a cast. The mean Activities Scale for Kids score at six weeks was 92.8 in the splint group and 91.4 in the cast group (difference 1.44, 95% confidence interval [CI] -1.75 to 4.62). Thus, the null hypothesis that the splint is less effective by at least seven points was rejected. The between-group difference in angulation at four weeks was not statistically significant (9.85° in the splint group and 8.20° in the cast group; mean difference 1.65°, 95% CI -1.82° to 5.11°), nor was the between-group differences in range of motion, grip strength and complications.

INTERPRETATION

In children with minimally angulated fractures of the distal radius, use of a splint was as effective as a cast with respect to the recovery of physical function. In addition, the devices were comparable in terms of the maintenance of fracture stability and the occurrence of complications. (ClinicalTrials.gov trial register no. NCT00610220.).

Common pediatric fractures treated with minimal intervention

The unlikely event of long-term complications in some pediatric fractures, such as midclavicular fractures, has allowed for management of these injuries with interventions that support the injured extremity rather than immobilize it while healing occurs. However, there is currently a growing body of evidence that advocates for this approach for some of the most frequently encountered pediatric fractures also at very low risk of future problems but, in contrast, have conventionally been managed with orthopedic consultation and rigid casting for several weeks. Therefore, this article will review the evidence that recommends that management of some of the most common upper and lower pediatric extremity fractures be treated with minimal interventions, such as removable splints and follow-up with a primary care provider.

Distal radius fractures in children: substantial difference in stability between buckle and greenstick fractures

BACKGROUND AND PURPOSE

Numerous follow-up visits for wrist fractures in children are performed without therapeutic consequences. We investigated the degree to which the follow-up visits reveal complications and lead to change in management. The stability of greenstick and buckle fractures of the distal radius was assessed by comparing the lateral angulation radiographically.

PATIENTS AND METHODS

The medical records of 305 distal radius fractures in patients aged less than 16 years treated at our institution in 2006 were reviewed, and any complications were noted. The fracture type was determined from the initial radiographs and the angulation on the lateral films was noted.

RESULTS

Only 1 of 311 follow-ups led to an active intervention. The greenstick fractures had more complications than the buckle fractures. The lateral angulation of the buckle fractures did not change importantly throughout the treatment. The greenstick fractures displaced 5 degrees on average, and continued to displace after the first 2 weeks. On average, the complete fractures displaced 9 degrees .

CONCLUSION

Buckle fractures are stable and do not require follow-up. Greenstick fractures are unstable and continue to displace after 2 weeks. Complete fractures of the distal radius are uncommon in children, and highly unstable. A precise classification of fracture type at the time of diagnosis would identify a smaller subset of patients that require follow-up.
