Summary

Pediatric diaphyseal femur fractures that occur in children aged 6 months to 5 years old are traditionally treated with hip spica casting. However, recent studies suggest that functional bracing may offer clinical and financial benefits, yet there's a lack of prospective trials comparing these two treatment methods. This single-center randomized-control trial aims to assess subjective and objective clinical outcomes as well as financial aspects of functional bracing versus spica casting. Functional bracing, proposed as a potentially superior alternative, may address caregiver challenges and reduce costs by avoiding operating room time and hospital admissions. The study will evaluate fracture reduction, time to union, functional outcomes, and caregiver satisfaction. Additionally, a comprehensive cost-effectiveness analysis will be conducted. Ultimately, this research aims to inform clinical decision-making regarding the optimal management of pediatric femur fractures, considering both clinical effectiveness and economic implications.

Detailed description

Pediatric diaphyseal femur fractures are a common orthopedic injury in children, with about one-third occurring in patients under the age of five. These fractures require effective management to promote optimal healing and functional recovery. In the 6-month to 5-year-old age group, diaphyseal femur fractures have traditionally been treated with a hip spica cast. Application of a hip spica cast typically occurs in the operating room (OR) under general anesthesia given that patients must undergo prolonged sedation for cast application. Caring for a child with a hip spica cast presents significant challenges for caregivers due to the cast's cumbersome size and restricted mobility. This makes routine activities such as daily hygiene, toileting and skin surveillance difficult for caregivers. An ecological study performed by Kocher et al. found that spica casting places a greater burden on family functioning than medical treatment in children with serious chronic medical conditions including diabetes, renal failure, and juvenile rheumatoid arthritis.1 Kramer et al. have recently proposed the use of functional bracing as an equally effective alternative to traditional hip spica casting for the treatment of pediatric diaphyseal femur fractures. In their study, they found no differences in the correction and maintenance of fracture alignment, time to union and functional outcomes2. The use of a prefabricated and adjustable functional brace was suggested to be better tolerated by patients and their parents as the open design allows for improved hygiene, ease of cleaning, toileting, skin surveillance and improved positional movement. From a cost-effectiveness analysis perspective, it has been inferred that the overall cost of functional bracing compared to spica casting is lower as it can be applied in the emergency department without the need for a general anesthetic or operating room time. Furthermore, we hypothesize that functional bracing will also decrease visits to orthopedic clinics for cast-related issues which will further decrease the overall costs associated with the treatment of pediatric diaphyseal fractures with a functional brace when compared to a hip spica cast. Having said this, no comprehensive cost-effectiveness analysis studies have been performed to our knowledge and there is minimal literature comparing functional bracing versus spica casting for the treatment of pediatric diaphyseal femur fractures. This proposed study aims to address this gap by conducting a randomized prospective study comparing functional bracing and spica casting for the treatment of pediatric diaphyseal femur fractures by evaluating maintenance of fracture reduction, time to union, leg-length, functional outcomes, complications, parent/caregiver satisfaction with the treatment as well as performing a supplemental comprehensive cost-effectiveness analysis.

Interventions

Type	Name	Description
DEVICE	Functional Bracing	Premade fabricated braces in three sizes (small, medium and large) that have been designed for the pediatric age group between 0-5 years old will be stocked at the Alberta Children's Hospital. Braces will be applied to participants in the emergency department. As these braces are designed to allow for positional adjustments, if deemed necessary adjustments will be made by the attending orthopaedic surgeon at subsequent follow-up visit(s).
DEVICE	Hip Spica Cast	The current standard of care for diaphyseal pediatric hip fractures in children aged 6 months to 5 years old is hip spica casting. A hip spica is a hard cast that covers a child's body from the chest down to their knees or ankles allowing for fracture immobilization to promote healing. Application of the spica cast occurs in the operating room and requires a general anaesthetic. Caring for a child in a hip spica cast presents significant challenges for caregivers due to the cast's cumbersome size and restricted mobility which makes routine caregiver activities like daily hygiene, toileting, transportation and skin surveillance difficult. Inadequate maintenance of the spica cast may result in skin complications, necessitating extra visits for cast adjustments, or potentially requiring revision casting in the operating room.
