Epidemiologic pattern of paediatric supracondylar fractures of humerus in a teaching hospital of rural India: A prospective study of 263 cases

Medium-term clinical results in the treatment of supracondylar humeral fractures in children: does the surgical approach impact outcomes?

BACKGROUND

Recent literature has found a consensus in favor of conservative treatment for type II supracondylar humeral fractures (SCHF). This retrospective observational study compares the short- to medium-term functional outcomes of conservative versus surgical treatment in 31 patients with SCHF (Gartland II and III) to assess the potential superiority of one approach over the other.

MATERIALS AND METHODS

Thirty-one pediatric patients treated for SCHF-19 classified as Gartland II and 12 as Gartland III-were assessed in our department. Eight patients underwent closed reduction and cast immobilization, 22 were treated with closed reduction and percutaneous pinning, and one underwent open reduction and internal fixation with plates. Clinical and functional data were collected during follow-up, including elbow and forearm range of motion (ROM), grip strength, carrying angle, Flynn's criteria, and Disabilities of the Arm, Shoulder, and Hand (DASH) score.

RESULTS

The average follow-up was 3.3 years (± 1.4 years). All patients demonstrated good functional recovery. According to Flynn's criteria, 85% and 81% of the patients achieved a satisfactory outcome in elbow flexion and carrying angle, respectively. No cases of nerve injuries were reported. Four patients developed cubitus varus in the Gartland II group, which was treated with closed reduction and casting with the initial alignment maintained (without a loss of reduction during the first week). However, compared to this group that was conservatively treated, functional and clinical outcomes were significantly better in the group with SCHF Gartland II treated with reduction and pinning (p < 0.05).

CONCLUSIONS

Although some recent studies have demonstrated positive outcomes with conservative treatment for both Gartland IIA and IIB fractures, the short- to medium-term functional results in our study emphasize that superior outcomes were obtained with surgical treatment for Gartland II fractures when compared to those treated conservatively.

TRIAL REGISTRATION

This study was performed in line with the principles of the Declaration of Helsinki. Ethics approval was obtained from our institute's ethics committee (registry no. 3511).

Epidemiologic investigation of pediatric distal humerus fractures: An American insurance claims database study

BACKGROUND

Distal humerus elbow fractures are one of the most common traumatic fractures seen in pediatric patients and present as three main types: Supracondylar (SC), lateral condyle (LC), and medial epicondyle (ME) fractures.

AIM

To evaluate the epidemiology of pediatric distal humerus fractures (SC, LC, and ME) from an American insurance claims database.

METHODS

A retrospective review was performed on patients 17 years and younger with the ICD 9 and 10 codes for SC, LC and ME fractures based on the IBM Truven MarketScan® Commercial and IBM Truven MarketScan Medicare Supplemental databases. Patients from 2015 to 2020 were queried for treatments, patient age, sex, length of hospitalization, and comorbidities.

RESULTS

A total of 1133 SC, 154 LC, and 124 ME fractures were identified. SC fractures had the highest percentage of operation at 83%, followed by LC (78%) and ME fractures (41%). Male patients were, on average, older than female patients for both SC and ME fractures.

CONCLUSION

In the insurance claims databases used, SC fractures were the most reported, followed by LC fractures, and finally ME fractures. Age was identified to be a factor for how a pediatric distal humerus fractures, with patients with SC and LC fractures being younger than those with ME fractures. The peak age per injury per sex was similar to reported historic central tendencies, despite reported trends for younger physiologic development.

Extra Lateral Pin or Less Radiation? A Comparison of Two Different Pin Configurations in the Treatment of Supracondylar Humerus Fracture

Background: Closed reduction and percutaneous fixation are the most commonly used methods in the surgical treatment of supracondylar humerus fractures. The pin configuration changes stability and is still controversial. The aim of this study was to investigate the relationship between surgical duration and radiation dose/duration for different pinning fixations. Methods: A total of 48 patients with Gartland type 2, 3, and 4 supracondylar fractures of the humerus were randomized into two groups—2 lateral and 1 medial (2L1M) pin fixation (n = 26) and 1 lateral 1 medial (1L1M) pin fixation (n = 22). A primary assessment was performed regarding surgical duration, radiation duration, and radiation dose. A secondary assessment included clinical outcome, passive range of motion, radiographic measurements, Flynn’s criteria, and complications. Results: There were 26 patients in the first group (2L1M) and 22 patients in the second group (1L1M). There was no statistical difference between the groups regarding age, sex, type of fracture, or Flynn’s criteria. The overall mean surgical duration with 1L1M fixation (30.59 ± 8.72) was statistically lower (p = 0.001) when compared to the 2L1M Kirschner wire K-wire fixation (40.61 ± 8.25). The mean radiation duration was 0.76 ± 0.33 s in the 1L1M K-wire fixation and 1.68 ± 0.55 s in the 2L1M K-wire fixation. The mean radiation dose of the 2L1M K-wire fixation (2.45 ± 1.15 mGy) was higher than that of the 1L1M K-wire fixation (0.55 ± 0.43 mGy) (p = 0.000). Conclusions: The current study shows that although there is no difference between the clinical and radiological outcomes, radiation dose exposure is significantly lower for the 1L1M fixation method.

Correlation of Fall Height, Fracture Severity and Clinical Outcome in Pediatric Supracondylar Fractures—A Retrospective Analysis with an Observation Period of 20 Years

The most common cause leading to supracondylar humerus fractures in children is falling onto an outstretched arm. A correlation between fall height and fracture severity may be assumed but has not yet been described. The aim of this study was to show that fracture severity increases with fall height. Furthermore, the correlation between fracture severity and outcome was examined. A total of 971 children with supracondylar humerus fractures between January 2000 and December 2019 were included in this study. The correlations between fall height and fracture severity and between fracture severity and outcome were assessed. Increasing fall height correlates with fracture severity (p < 0.001; r = 0.24). Furthermore, the incidence of complications increases with fracture severity and a correlation was present accordingly (p < 0.001; r = 0.28). A total of 30 (3.1%) patients showed limitations in range of motion and/or persistent neurologic deficits at the latest follow-up. Type I fractures rarely lead to subsequent limitations. The correlation between increasing fall height and fracture severity was significant. Furthermore, children with type III and IV supracondylar fractures are more likely to develop complications or restrictions in movement than children with type I and II fractures. Hence, the initial fall height may be an indirect indicator of a more or less favorable outcome.

The Effect of COVID-19 Pandemic on the Characteristics of Pediatric Supracondylar Fracture: A Retrospective Cohort Study

Background

Environmental factors play a key role in the occurrence of pediatric supracondylar humerus (SH) fracture which has been widely affected by the COVID-19 pandemic and the measures taken to curb its spread. In this study, we aim to investigate the ultimate impact coronavirus pandemic has had on SH fractures in children.

Materials and Methods

This retrospective cohort study compares SH fractures which occurred during the pandemic with their prepandemic counterpart in a pediatric trauma public hospital. Patient's data, submitted from February to July 2020 and 2019, were collected and divided into two groups based on fractures' time of occurrence, i.e., during or before the pandemic.

Results

There was no significant difference in terms of gender, type of fracture, injury location, and time of admission during a day between the aforementioned groups. However, in the pandemic group, patients were transferred to the operating room significantly quicker (odds ratio; 2.13 vs. 0.607, P = 0.01) and the surgery duration was shorter (40.17 ± 12.28 min vs. 49.11 ± 15.48 min, P = 0.011). It was found that the location of injury (home, school, etc.) varied between the two groups (P = 0.01) and the proportion of domestic injuries during the pandemic grew significantly (53.6% vs. 19.8%).

Conclusion

Although the incidence of pediatric SH fractures has decreased due to the closure of schools and sports clubs during the pandemic, domestic occurrence of the same fracture type has grown disproportionately. To prevent this trend, pediatric centers should educate parents on child safety measures and fracture risks during the lockdown.

Forearm Compartment Pressure Change in Children Operated for Supracondylar Humerus Fracture

BACKGROUND

The aim of this study is to examine the preoperative and postoperative forearm compartment pressures in patients treated operatively for Gartland type III extension type supracondyler humerus fractures and understand the course of these values over postoperative period.

METHODS

Deep volar compartment pressure of 31 patients were measured in the proximal one third of the forearm preoperatively, and measurements were continued every 4 hours for the first 24 hours after the operation with a catheter. Type of the reduction technique (open reduction vs. closed reduction), duration of surgery, the time from the injury to surgery were all evaluated.

RESULTS

In the measurements made immediately after the operation (0 h), a sudden increase in the compartment pressure was detected in all patients (15.0±5.9 to 27.9±7.5 mm Hg) independent of the reduction technique and gradually decreased over time. The mean compartment pressure at the 12th hour postoperatively was higher in the open reduction group than in the CR group (24.5±3.4, 20.7±6.7 mm Hg, respectively) ( P =0.044). The mean preoperative compartment pressure was 17.7±5.8 mm Hg in patients with a time from injury to surgery longer than 12 hours, and 12.4±4.8 mm Hg in patients with 12 hours or less ( P =0.006). The postoperative 0-, 12-, and 20-hour pressure values were higher in the >1 hour operation time group than in the ≤1 hour group and the differences were statistically significant ( P =0.046, 0.016, and 0.032, respectively).

CONCLUSIONS

In pediatric supracondylar humeral fractures, those who underwent open reduction had higher preoperative and postoperative compartment pressures. The reduction attempt was found to be a factor that increased the compartment pressure and after the operation, the compartment pressure values decrease gradually. Prolonged operative time (>1 h) and increased time from injury to operative fixation (>12 h) were associated with higher compartment pressures.

Evaluation of anterior approach in failed closed reduction and delayed presentation of supracondylar humerus fractures in children

BACKGROUND

The treatment of displaced paediatric supracondylar fracture is a challenging problem and requires strict vigilance and a proper management protocol. Prospective investigation of the treatment options for fractures that cannot be reduced by closed reduction is recommended in literature. Operative treatment is indicated for the fractures that cannot be reduced satisfactorily by closed methods. It is also considered the best option for late presenting fractures. The aim of this study was to assess and compare the clinical outcome using open reduction through anterior approach in delayed presentation and failed closed reduction of supracondylar fracture humerus in children.

MATERIALS AND METHODS

15 patients of failed closed reduction and 11 patients of delayed presentation of supracondylar humerus fractures were operated with anterior approach. The demographic data, time from injury to presentation and from admission to surgery, reasons for delayed presentation, type of fracture, operative findings and time, K-wire configuration, length of hospitalization, post operative complications were noted. The patients were followed up for a period of 12 months and final range of motion, Baumann's angle, and cosmetic, functional and overall outcome by Flynn's criteria were evaluated and analyzed.

RESULTS

The overall outcome was very satisfactory according to Flynn's criteria. 80.77% patients had excellent, 15.38% patients had good, and 3.85% patient had fair results with no poor results. Our results show distinct advantage of anterior approach which are on a par with or better than the previous studies using anterior approach, adding to their evidence.

CONCLUSION

Open reduction using anterior approach is a very safe, logical and effective technique of treating failed closed reduction or late presentation of supracondylar fractures humerus in children with excellent cosmetic and functional results, and offers distinctive advantage over other approaches.

Small incision reduction and external fixation for the treatment of delayed over fourteen days supracondylar humeral fractures in children

BACKGROUND

Supracondylar humeral fractures (SHF) are the most common type of fracture occurring at the distal humerus in children. In patients with delayed presentation of SHF, closed reduction is challenging to achieve with traditional reduction maneuvers. This study aimed to report the clinical results of pediatric SHF delayed over 14 days treated by closed reduction with a minimally invasive technique and external fixation and evaluate the efficacy of this technique.

METHODS

Between October 2010 and September 2018, children with delayed presentation of SHF over 14 days were retrospectively included in this study. The patients received closed reduction with a minimally invasive technique followed by external fixation. The demographics and radiographic data were collected. The Mayo Elbow Performance Score (MEPS) and the Flynn criteria were used to evaluate the clinical outcomes of treatments.

RESULTS

A total of 11 children (aged 4-13 years) with delayed presentation (range, 14-22 days) were recruited. They received surgery using closed reduction with a minimally invasive technique followed by external fixation. None of the surgery was done with the open method. After surgery, the patients' carrying angle returned to normal. The radiological union was evident in 8 to 12 weeks in all fractures without complications. Every patient had a good to excellent score on the MEPS and the Flynn criteria.

CONCLUSIONS

The results of this series indicated a satisfactory outcome in children with delayed more than 14 days of supracondylar humeral fractures. The closed reduction with a minimally invasive technique followed by external fixation is an alternative treatment for such injury.

Predictors of early elbow function following paediatric humeral supracondylar fractures: A retrospective analysis

Background

Supracondylar fracture usually occurs as a result of fall on an outstretched hand. Prompt management is essential to prevent complications. Functional outcome after management of this fracture may be predicted by some factors.

Aims

The study aimed to review the management of supracondylar fractures and determine what factors have an impact on the functional outcome of the elbow using MEPS score in the early post-operative period.

Patients and Methods

This study was a retrospective study of all patients with supracondylar fractures that presented at the accident and emergency department of a tertiary institution over a 2-year period. Their relevant data were retrieved from their folders and analysis done using SPSS 20. The MEPS score at 6 months was calculated. Multiple linear regressions were used to determine factors that can predict early elbow function using the MEPS score at 6 months.

Results

In the study, 61.4% (35) patients were males and 38.6% (22) females. The commonest mechanism of injury was fall on the outstretched hand (FOOSH), 70.2%. The mean duration of presentation to the hospital was 38 h (SD = 56.9). Among treatment offered to the patients, a higher number had open reduction with pinning. The mean postoperative Mayo elbow score was 87.6. Age of patients, Gartland type and the duration of cast immobilization were significant predictors of the MEPS at 6 months after treatment.

Conclusion

The Gartland type and duration of cast immobilization are the most important predictors of the MEPS score at 6 months in this study.

Aspects of Epidemiology and Treatment of Supracondylar Fractures of the Humerus in Children in South-Eastern Romania

Supracondylar fractures are frequently encountered in childre and have a high prevalence of associated complications. Supracondylar fractures, due to their frequency, aspect and the serious health problems that can result, require a rapid and precise intervention, based on a well-defined evaluation methodology

In this paper, we assess the epidemiology and the management of supracondylar fractures treated within the Surgery and Pediatric Orthopedics Clinic of the Emergency County Hospital of Constanta.

We conducted a retrospective study on 222 pediatric patients with supracondylar fractures of the humerus during between 2019 and 2021 treated in County Clinical Emergency Hospital of Constanta. The data was collected from the medical records of the patients recorded on the Clinic of Pediatric Surgery and Pediatric Orthopedics.

We obtained a higher percentage of males with fractures (60%). Falling from the same level was the main cause of fracture, followed at close distance by fall from different level, other causes, among which car accidents being observed less in our study.

Time trends in pediatric fractures in a Swedish city from 1950 to 2016

Background and purpose - As previous studies indicate time trends in pediatric fracture incidence, we followed the incidence in a Swedish city between 1950 and 2016.Patients and methods - Malmö city, Sweden had 322,574 inhabitants in 2015. We used diagnosis registry, charts, and radiographs of the only city hospital to classify fractures in individuals < 16 years in 2014-2016, and compared these with data from 1950-2006. We used joinpoint regression to analyze time trends and present results as mean annual percentage changes (APC). Differences between periods are described as incident rate ratios (IRR). To describe uncertainty, 95% confidence intervals (CI) are used.Results - During 2014-2016 the pediatric fracture incidence was 1,786 per 10⁵ person-years (boys 2,135 and girls 1,423). From 1950 onwards age-adjusted fracture incidence increased until 1979 in both boys (APC +1.5%, CI 1.2-1.8) and girls (APC +1.6%, CI 0.8-2.5). The incidence remained stable from 1979 to 2016 (APC in boys 0.0%, CI -0.3 to 0.3 and in girls -0.2%, CI -1.1 to 0.7). Age-adjusted incidence 2014-2016 was higher than 2005-2006 in girls (IRR 1.1, CI 1.03-1.3), but not in boys (IRR 1.0, CI 0.9-1.1).Interpretation - Fracture incidence was in girls higher in 2014-2016 than in 2005-2006. However, only with more than 2 measuring points are meaningful trend analyses possible. When we analyzed the period 1950-2016 with 17 measuring points and joinpoint regression, we found that fracture incidence increased in both sexes until 1979 but has thereafter been stable.

Comprehensive Analysis of Pediatric Supracondylar Fractures in the Emergency Department; A Single Center Experience

Objective:

To describe the demographic characteristics and to assess possible risk factors related to the moment of presentation at Emergency Department (ED) for pediatric humeral supracondylar fractures.

Methods:

This was cross-sectional study being conducted during 5-year period from 2013 to 2017 at ED of a regional hospital in Spain. We have included all the pediatric patients (<14 years) with supracondylar fractures referring to our center during the study period. The demographic, clinical and radiological characteristics of the patients were recorded. The outcome and treatment strategies were also recorded. The risk factors of the pediatric supracondylar fracture was also assessed in our series.

Results:

We have included 52 pediatric patients with supracondylar fractures in this series. The mean age was 7.48 ± 2.97 years with a minimum age of 2 years and a maximum of 14 years. Among the patients there were 32 (61.54%) male and 20 (38.46%) female. Age less than 7 years found to be a protective factor against unstable fractures [OR 0.33 (0.10 - 1.02)]. Fractures presented during daytime hours showed a greater instability [OR 3.49 (1.07-11.39)]. However, the risk of presentation at nighttime was higher during the summer months (June to September).

Conclusion:

The older is the child, the greater is the risk of suffering an unstable fracture, which increases the need for surgery. This risk is greater during the daytime. Otherwise, during the summer months, there is a higher risk of patient presentation at nighttime.

Supracondylar humerus fractures in low- and lower middle-income countries: a scoping review of the current epidemiology, treatment modalities, and outcomes

BACKGROUND

The purpose of this scoping review was to examine the nature and quality of research regarding paediatric supracondylar humerus (SCH) fractures in low and lower middle-income countries (LICs).

METHODS

We searched PubMed, Embase, Web of Science, and African Journals Online on January 9, 2018, for studies of SCH fractures in LICs. Studies were categorized by geographic region, Gartland classification of included patients, and study design. We evaluated each study's methodology and conclusions.

RESULTS

Out of 1805 results, we analyzed 105 studies, most of which included type 3 fractures only (66%). Many were conducted in South Asia (58%) and assessed treatment outcomes (78%). Most of the studies had level IV evidence (67%). Common limitations of research were small sample size (12%) and inadequate follow-up (6%). Epidemiological studies concluded that SCH fractures are more common among male children, are usually secondary to falls, and rarely present with nerve injuries. Most therapeutic studies reported outcomes of surgery (91%). Thirteen studies concluded that all-lateral versus cross-pinning techniques have similar outcomes. Seven studies reported preference for closed reduction over open reduction, when intra-operative fluoroscopy was available. Most common outcome measures were Flynn criteria (77%) and range of motion (53%). None of the papers looked at treatment costs.

CONCLUSIONS

Our data show a predominance of small level IV studies from LICs, with few studies of higher level of evidence. Many studies examined controversies with surgical technique, similar to studies performed in high-income countries. Few studies examined non-operative treatment, which is commonly the predominant treatment available for patients in LICs. Further investigation of common treatment modalities and outcomes for SCH fractures in LICs is needed.

Sex-based differences in pediatric supracondylar humerus fractures

Supracondylar humerus (SCH) fractures are reported to be approximately twice as common among boys as among girls. Little is known about sex-associated differences in fracture patterns and complications. We compared the incidence of pediatric SCH fractures, injury mechanism (high-energy or low-energy), fracture subtypes, associated neurologic injuries, and treatment types by patient sex.We reviewed 1231 pediatric SCH fractures treated at 1 center from 2008 to 2017, analyzing sex distributions overall and by year and fracture subtype. We noted patient demographic characteristics, injury mechanisms, neurologic injuries, and treatments (nonoperative or operative). Binomial 2-tailed, chi-squared, and Student's t tests were used for analysis. Multiple logistic regression was performed to assess associations between sex, age, and injury mechanism. Alpha = 0.05.We found no significant difference in the distribution of girls (52%) vs boys (48%) in our sample compared with a binomial distribution (P = .11). Annual percentages of fractures occurring in girls ranged from 46% to 63%, and sex distribution did not change significantly over time. The mean (± standard deviation) age at injury was significantly younger for girls (5.5 ± 2.5 years) than for boys (6.1 ± 2.5 years) (P < .001). High-energy injury mechanism was associated with older age (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.03-1.06) but not male sex (OR, 1.04; 95% CI, 0.98-1.1). The overall incidence of neurologic injury was 9.5% but boys did not have greater odds of sustaining neurologic injury (OR, 1.03; 95% CI, 1.0-1.1). We found no sex-associated differences in the distribution of Gartland fracture subtypes (P = .13) or treatment type (P = .39).Compared with boys, girls sustain SCH fractures at a younger age. SCH fractures were distributed equally among girls and boys in our sample. Patient sex was not associated with fracture subtype, injury mechanism, neurologic injury, or operative treatment. These findings challenge the perception that SCH fracture is more common in boys than girls.Level III, retrospective study.
