Date: July 23, 2025 Dr. Andrew Tagg Guest Skeptic: Dr. Andrew (Andy) Tagg is an Emergency Physician with a special interest in education and lifelong learning. He is the co-founder and website lead of Don’t Forget the Bubbles (DFTB). Case: A two-year-old boy presents to your pediatric emergency department (ED) with a limp and refusal to bear weight. His parents aren’t exactly sure what happened. They were at the park and suspected that he might have twisted his leg coming down a slide. On your exam, he does not have a fever. He does not have any swelling or deformity of his bilateral lower extremities. You order X-rays, which confirm a nondisplaced spiral fracture of the distal tibia, a classic toddler’s fracture. After you disclose his diagnosis, his worried parents ask you, “A fracture? Does that mean it’s broken? Will he need to get a cast? He’s such an active little guy, typically.” Background: Toddler’s fractures are subtle, nondisplaced spiral fractures of the tibia. They typically occur in children between the ages of 9 months and 4 years. They often present in children who are just beginning to walk, hence the term “toddler’s fracture.” These kids can come in with inability to bear weight, a limp, or nonspecific pain. Another challenge is that the history you get may or may not help guide you. These injuries usually result from low-energy trauma, such as a twisting injury during a fall. That can happen multiple times a day when you’re learning to walk! The mechanism of injury is so subtle sometimes that parents or caretakers may not recall any inciting event. The findings on X-ray can be quite subtle as well. AP and lateral views may reveal a very small hairline fracture that’s easily missed. In some situations, X-rays will be negative despite clinical exam findings suggestive of a toddler’s fracture. In those situations, repeated X-rays in a week or so can show some evidence of periosteal reaction. The traditional management has included immobilization with a long leg or short leg cast, based on the belief that toddlers are unlikely to limit activity independently and require rigid immobilization to promote healing and pain relief. However, growing concerns about the discomfort, skin breakdown, need for follow-up visits, and potential complications from casting have led to interest in less restrictive treatments. such as removable walking boots. Clinical Question: In children with radiographically confirmed toddler’s fractures, is treatment with a removable walking boot noninferior to a circumferential cast? Reference: Boutin A, et al. Removable Boot vs Casting of Toddler’s Fractures: A Randomized Clinical Trial. JAMA Pediatr. Published April 2025. Population: Children aged 9 months to 4 years with radiograph-visible tibial toddler’s fractures seen in 4 Canadian pediatric emergency departments. Exclusion: Presented more than 5 days after injury or had an increased risk for pathological fracture or delayed healing Intervention: Removable prefabricated walking boot. Parents were told to use the boot for one week, then use it as needed for symptoms for up to three weeks. This was based on caregiver discretion, with no scheduled follow-up. Comparison: Standard circumferential casting. This varied across sites: Two sites did a long-leg splint in the ED, followed by a fiberglass cast. Another site did a short or long leg splint/cast in the ED, followed by a long leg fiberglass cast. The final site placed a short-leg splint in the ED, followed by a short-leg fiberglass cast. The casts were applied within seven days of the ED visit. Two sites had casts that were peelable, meaning they could be removed by caregivers at home. The other two sites had patients return to the clinic for cast removal. Outcome: Primary: Evaluation Enfant Douleur (EVENDOL) pain score at 4 weeks Secondary: Return to activity, complications, caregiver satisfaction, care burden, healthcare utilization. Trial: Pragmatic, multicenter, assessor-masked, noninferiority randomized clinical trial Authors’ Conclusions : In this multicenter randomized clinical trial examining the management of children with TF, a removable boot without physician follow-up was noninferior to circumferential casting with respect to pain recovery. While there was a clinically relevant but not statistically significant trend toward more skin complications in the boot group, there was no difference in caregiver satisfaction, and the boot strategy demonstrated reduced childcare-related challenges Quality Checklist for Randomized Clinical Trials: The study population included or focused on those in the emergency department. Yes The patients were adequately randomized. Yes The randomization process was concealed. Yes The patients were analyzed in the groups to which they were randomized. Yes The study patients were recruited co
