Follow-Up Care of Distal Radius Buckle Fractures

Ann Emerg Med. 2021;77(2):163-173; doi:10.1016/j.annemergmed.2020.07.039Investigators from the University of Toronto conducted a randomized controlled trial to assess outcomes associated with home management versus physician follow-up in children with distal buckle fractures. Children were eligible if they were 5-17 years old and were diagnosed in the study ED within the previous 3 days with a distal radius buckle fracture during the 2018-2019 study period. The standard management for all patients diagnosed with a distal buckle fracture at the study ED is a removable splint. All participants completed a demographic survey at enrollment as well as a baseline modified Activities Scale for Kids-38 (ASKp38) scale that assessed wrist function the week before injury (with the average score for patients with no disabilities being 95%).Participants were randomized to either removal of the splint at home with physician follow-up as needed or to see their primary care physician 1-2 weeks after the ED visit. All participants were advised to wear the splint continuously (except for bathing) for the first week and then as needed to manage pain or swelling symptoms. All participants were advised to restrict activities that could lead to reinjury for 6 weeks.The primary outcome was ASKp38 scores at 3 weeks post-ED visit, assessed via telephone. A secondary outcome was health care resource use and parental expenses related to the child’s injury, assessed by parent report at 3 and 6 weeks post-ED visit and medical records. Total patient health care costs were estimated by multiplying health care resources data by corresponding unit prices. The investigators assessed outcomes by allocation arm using an intention-to-treat analysis.There were 149 participants enrolled, 73 in the home management group and 76 in the primary care physician follow-up group. Follow-up was completed for 90.4% of participants in the home management group and 88.2% of the physician follow-up group at 3 weeks, and 89% and 86.8%, respectively, at 6 weeks. There were no significant differences in baseline demographics or baseline ASKp38 scores. Mean ASKp38 scores at 3 weeks were similar between both groups (95.4% and 95.9% in the home management and physician follow-up groups, respectively). Total mean healthcare and parent costs in the physician follow-up group were greater than in the home management group ($149.10 vs $26.80, respectively).The investigators conclude that home removal of splints for distal buckle fractures is noninferior to physician follow-up and less costly.Dr Bechtel has disclosed no financial relationship relevant to this commentary. This commentary does not contain a discussion of an unapproved/investigative use of a commercial product/device.Buckle (torus) fractures of the distal radius are the most common fractures in children.1 There are many ways these fractures can be managed, as they are very stable and have an excellent prognosis. Primary care physicians are becoming the standard of care for follow-up of buckle fractures instead of orthopedic or fracture clinic follow-up. Primary care physician follow-up for distal forearm buckle fractures has demonstrated excellent recovery and management mainly based on patient symptoms rather than frequent radiographic follow-up common to orthopedists or fracture clinics.2 The current investigators sought to determine whether symptomatic home management versus primary care provider follow-up of torus fractures had equivalent functional outcomes in children managed with a removable splint.Indeed, the authors did find that home management was just as efficacious as primary care provider follow-up in terms of functional use scores at 3 weeks. Notably, children who were managed at home had even lower costs and fewer follow-up radiographs obtained than children who had follow-up with their primary care provider. There are, however, 2 significant limitations of the current study that should be noted. The first is that most of the population had post-secondary school education and telephone and electronic access and had a primary care provider. Thus, extrapolating the results to a different population (eg, lower parental education, lack of telephone access or a primary care provider) is not possible at this time. The second limitation is that the population was also primarily English-speaking, so it is likely not practical to expect similar results in a non-English speaking population of caregivers based on the current study.In English-speaking families with telephone and electronic access and a primary care physician, at-home management of children with torus fractures with a removable splint is less costly and just as efficacious as follow-up with a primary care physician.The benefits that accrue with home splint removal are potentially more than financial. Parental time away from employment or other priorities, as well as school absence by affected children, are obviated by home management of distal radius fractures.
