Increase in surgical fixation of pediatric midshaft clavicle fractures since 2008

A Rare Combined Injury in Children during Side Impact: The Possible Mechanism and Treatment Results

OBJECTIVE

Proximal humeral fracture combined with contralateral midshaft clavicle fracture is an extremely rare injury in children. Few studies focus on the injury mechanism and treatment scheme. The aim of this study is to propose the possible mechanism of this injury and present the treatment results.

METHODS

This retrospective study included children diagnosed with proximal humeral fractures combined with contralateral midshaft clavicle fractures from August 2016 to March 2019 in the corresponding author's institution. The patients received elastic stable intramedullary nails and external fixation as treatment. The radiological and clinical outcomes of treatments were evaluated using the imaging and the Constant-Murley score (CMS) in follow up.

RESULTS

Twelve patients (eight males and four females) with an average age of 7.83 years old (age 5-12) were included in this research. All the patients had suffered a side impact in a road traffic accident or outdoor environment. Hypothesis about the mechanism was the proximal humerus was directly impacted at first and caused the surgical neck fracture, then the contralateral shoulder hits the solid object and the contralateral midshaft clavicle was fractured. During the average 45.2 months (range 36-57) follow-up, all the patient's fractures achieved clinical and radiological union before 14 weeks without complications. Every patient had a satisfactory score (range from 92 to 100) on the CMS criteria for both shoulders.

CONCLUSION

The hypothesis about the mechanism of this combined injury in this study sounds reasonable. It highlights the need for safety-related education about using a safety seat or wearing a seat belt to parents and caregivers, so as to avoid such injury even if the treatment with external fixation (EF) and proximal humeral and elastic stable intramedullary nailing (ESIN) showed good results.

Fractures in Children Due to Firearm Activity

The purpose of this study was to investigate fracture patterns due to pediatric firearm injuries. The data used was from the US Firearm Injury Surveillance Study 1993–2019. Over these 27 years, there were 19,033 children with fractures due to firearm activity with an average age of 12.2 years; 85.2% were boys and the firearm was a powder type in 64.7%. The finger was the most common fracture location, while the tibia/fibula was the most common location for those admitted to the hospital. Children ≤ 5 years of age sustained more skull/face fractures; most spine fractures occurred in the 11–15-year age group. The injury was self-inflicted in 65.2% of the non-powder and 30.6% of the powder group. The injury intent was an assault in 50.0% of the powder and 3.7% of the non-powder firearm group. Powder firearms accounted for the majority of the fractures in the ≤5 and 11–15 year-olds, non-powder firearms accounted for the majority of the fractures in the 6–10 year-olds. Injuries occurring at home decreased with increasing age; there was an increase in hospital admissions over time. In conclusion, our findings support the need for safe storage of firearms in the home away from children. This data will be helpful to assess any changes in prevalence or demographics with future firearm legislation or other prevention programs. The increasing acuity of firearm-associated injuries seen in this study is detrimental to the child, impacts familial wellbeing, and results in significant financial costs to society.

Clavicular Fractures in the Adolescent

➤

Current evidence suggests that the majority of clavicular fractures in adolescents can and should be treated nonoperatively.

➤

Although rare, in certain patients or fracture patterns, nonoperative management may be associated with delayed healing, prolonged disability, and/or poor functional outcome requiring secondary reconstruction.

➤

When warranted, primary open reduction and internal fixation with plate and screw application has consistently good outcomes with a low complication rate, with the most common complication being implant-related symptoms requiring a secondary surgical procedure for implant removal.

➤

Prospective, comparative studies examining operative and nonoperative treatment, including measures of early return to function, injury burden, return to athletic activity, complication and reoperation rates, and shoulder-girdle-specific, long-term outcome measures are warranted to further elucidate which fractures may benefit from primary fixation.

Trends in the Treatment of Adolescent Clavicle Fractures: Are We Listening to the Evidence?

BACKGROUND

From 1999 to 2011, studies demonstrated an increasing trend toward surgical management of adolescent clavicle fractures. The purpose of this study was to examine more recent trends of surgical management of closed clavicle fractures in adolescent patients over the past decade.

METHODS

A retrospective cohort study was conducted using the PearlDiver database. Patients with clavicle fractures from 2011 to 2021 were identified and stratified by age, sex, and year of their fracture. Categorical variables were compared with a chi square test, and continuous variables were compared with the Welch t test or Mann-Whitney U test.

RESULTS

Overall, there was a significant increase in the percentage of patients surgically treated by open reduction and internal fixation from 2016 to 2021 compared with 2011 to 2015 (8.58% vs. 7.34%, P < 0.001). When stratified by age, both the 10 to 14-year group (3.80% vs. 3.10%, P < 0.001) and the 15 to 18-year group (15.41% vs. 12.84%, P < 0.001) demonstrated significant increases in the percentage of patients surgically treated.

CONCLUSION

Despite increasing literature demonstrating high revision surgery rates for surgical treatment of adolescent clavicle fractures with no difference in functional outcomes, this study demonstrated a notable increase in the rate of surgical treatment of adolescent clavicle fractures from 2011 to 2021 in the United States.

Plating versus elastic stable intramedullary nailing for displaced pediatric midshaft clavicular fractures

Introduction

Traditionally, operative treatment for displaced midshaft clavicle fractures in adolescents has been achieved by using a plate and screws. However, a minimally invasive trend has led surgeons to use the elastic stable intramedullary nail (ESIN) for displaced midshaft clavicle fractures. This study aims to compare the clinical outcomes of adolescent patients who were operated on with an ESIN vs. a plate.

Methods

All patients aged between 10 and 14 years with displaced midshaft clavicle fractures who were operated on at our institute between January 2014 and January 2018 were reviewed retrospectively. The preoperative data, including baseline information on the patients, and types of surgical procedure were collected from the hospital database. The postoperative data, including clinical outcome and complications, were collected during the follow-up visits. Clinical outcome was evaluated during outpatient visits using the American Shoulder and Elbow Surgeons (ASES) score. The scar problem was evaluated according to the Scar Cosmesis Assessment and Rating (SCAR) scale.

Results

A total of 73 patients were included. Patients were categorized into two groups: ESIN (n = 45; 27 males, 18 females) and plate (n = 28; 17 males, 11 females), according to surgical technique. The average age of the patients in the ESIN group was 12.2 ± 1.5 years, and that in the plate group was 12.2 ± 1.4 years. The ESIN group presented significantly less operative time (31.1 vs. 59.8 min), a shorter hospital stay (1.5 vs. 2.5 days), and a smaller incision (2.4 vs. 5.4 cm) as compared to the plate group (P < .001). The rate of scar concern was much higher in the plate group (71.4%) than the ESIN group (22.2%) (P < .001). There was no statistically significant difference in shoulder function between the ESIN group and the plate group at different time points.

Conclusion

A conservative approach remains the first choice for a pediatric clavicle fracture. Both the ESIN and the plate are safe and effective treatment methods for displaced midshaft clavicle fractures in adolescents. The ESIN is superior to the plate given its shorter operative time, shorter hospital stay, lower rate of scar concern, and easier implant removal.
