Notable findings in pediatrics regarding the treatment of fractures, infection, early-onset scoliosis, and more are presented in the new JBJS Guest Editorial What’s New in Pediatric Orthopaedics. Here, we highlight the 5 most compelling studies, as selected by author Christina K. Hardesty, MD.
Trauma
Researchers investigated whether the time to treatment of supracondylar humeral fractures affected clinical outcomes in pediatric patients. A total of 472 patients were included; 435 underwent surgical treatment within 18 hours of presentation and 37 underwent treatment after 18 hours. No differences in postoperative complications, including malunion, nonunion, stiffness, infection, and nerve injury, were found between the groups, even when Type II Gartland fractures were excluded1.
A randomized controlled trial compared 2 treatments for distal radial buckle fracture with respect to pain and function in patients 4 to 15 years old. Of the 965 patients included, 489 received a bandage and 476 received rigid immobilization. The groups had equivalent pain at 3 days following treatment and demonstrated no differences in pain or function during the 6-week follow-up period2. These findings suggest “that we may be overtreating distal radial buckle fractures in children when we routinely utilize rigid immobilization,” says Guest Editorial author Dr. Hardesty, adding that this study “has the potential to change all our practices, providing children with less rigid immobilization for buckle fractures.”
Infection
A study assessed the utility of procalcitonin, a protein released by tissues in response to bacteria or other infection, as a biomarker for musculoskeletal infection in pediatric patients. Procalcitonin was compared with traditional biomarkers in 188 children and found to outperform white blood-cell count, C-reactive protein, and absolute neutrophil count. A procalcitonin level of >0.1 ng/mL predicted deep infection in 84.7% of cases. Combining procalcitonin with C-reactive protein, erythrocyte sedimentation rate, and temperature improved diagnostic accuracy to 89.4%3.
Upper Extremity
The Function after Adolescent Clavicle Trauma and Surgery (FACTS) study group evaluated clavicular remodeling in 98 adolescent patients with completely displaced fractures treated nonoperatively. The study authors reported a high remodeling rate and observed that remodeling continued even beyond adolescence. Complete or near-complete remodeling was demonstrated in 85% of patients <14 years old and 54% of patients ≥14 years old at the time of injury4.
Spine
A Level II study published in JBJS utilized a novel dynamic MRI technique to evaluate pulmonary function in 39 patients treated surgically for thoracic insufficiency syndrome. Patients with thoracic insufficiency syndrome demonstrated improvement in tidal volumes and hemidiaphragm positions following the surgical procedure. Additionally, decreased deviation from normality was demonstrated in this group when their preoperative and postoperative parameters were compared with those of healthy children5.
