Conditions

7-12 Year Old, AO Classification 22D/2.1-5.2, Both Bone Forearm Fracture

Brief summary

The forearm is the most common fracture location in children, with an increasing incidence. Displaced forearm shaft fractures have traditionally been treated with closed reduction and cast immobilization. Diaphyseal fractures in children have poor remodeling capacity, and malunion can thus cause permanent cosmetic and functional disability. Internal fixation especially with flexible intramedullary nails has gained increasing popularity, without evidence of a better outcome compared to closed reduction and cast immobilization.

Detailed description

This is a multicenter, randomized superiority trial comparing closed reduction and cast immobilization to flexible intramedullary nails in 7-12 year old children with \> 10° of angulation and/or \> 10mm of shortening in displaced both bone forearm shaft fractures (AO-pediatric classification: 22D/2.1-5.2). A total of 78 patients with minimum 2 years of expected growth left are randomized in 1:1 ratio to either treatment group. The study has a parallel non-randomized patient preference arm. Both treatments are performed under general anesthesia. In the cast group a long arm cast is applied for 6 weeks. The flexible intramedullary nail group is immobilized in a collar and cuff sling for 4 weeks. Data is collected at baseline and at each follow-up until 1 year. Primary outcome is 1) PROMIS Pediatric Item Bank v2.0 - Upper Extremity and 2) forearm pronation-supination range of motion at one-year follow-up. Secondary outcomes are Quick DASH, Pediatric pain questionnaire, Cosmetic VAS, wrist range of motion as well as any complications (malunion, delayed union, non-union or deep wound infection, peripheral nerve injury, need for re-intervention during 1-year follow-up) and costs of treatment. The investigators hypothesize that flexible intramedullary nailing results in a superior outcome.

Design outcomes

Primary

MeasureTime frameDescription
PROMIS Pediatric Item Bank v2.0 - Upper Extremity12 monthsWe aim to confirm that 75 percent of FIN patients have a better PROMIS UE score than what the mean score of the cast patients will be assuming both groups have the same standard deviation. PROMIS (Patient-Reported Outcomes Measurement Information System) scores are normalized to a mean score of 50, standard deviation of 10, with a theoretical range of 0 to 100. A higher score corresponds to a greater amount of the domain being measured.
Pro-supination12 monthsDifference (percent) in forearm pronation-supination range of motion (ROM) at one-year follow-up in comparison to uninjured side.

Secondary

MeasureTime frameDescription
Measurement Model for the Pediatric Quality of Life Inventory Pediatric Pain Questionaire (PEDS QL PPQ)6 weeks, 3, 6 and 12 monthsMinimum value 0 maximum value 10. Higher value indicates higher pain intensity
Need for re-interventions6 weeks, 3, 6 and 12 monthsMinimum value 0 no maximum value. Lower value indicates better outcome.
Rate of participants with malunion6 weeks, 3, 6 and 12 monthsmalunion, delayed union (defined as nonunion at 3 months or later), pseudoarthrosis (defined as 3 cortices out of 4 not united at 6 months or later)
Adverse effects6 weeks, 3, 6 and 12 monthsadverse effects (wound infection, nerve or/and tendon damage)
Quick Disabilities of the Arm, Shoulder and Hand score6 weeks, 3, 6 and 12 monthsMinimum value is 0 and maximum 100. Higher value indicates worse function. Statistically significant difference in QuickDASH score is 6.8 (18) at 12 months FU.
PROMIS Pediatric Item Bank v2.0 - Upper Extremity6 weeks, 3, 6 monthsDifference between treatment groups
Upper limb ROM6 weeks, 3, 6 monthsDifference (percent) in elbow, wrist flexion extension and pronation-supination in comparison to uninjured side
Return to sport/musical instrument and level6 weeks, 3, 6 and 12 monthsLevel of practiced sport or musical instrument before and at end of trial, as well as time from injury to return to hobby is registered.
Cosmetic VAS6 weeks, 3, 6 and 12 monthsMinimum value 0 maximum value 10. Higher value indicates better satisfaction
Measurement Model for the Pediatric Quality of Life Inventory (PedsQL)6 weeks, 3, 6 and 12 monthsMinimum value is 0 and maximum value is 100. Higher score indicates better health related quality of life.
