Study Description

Brief summary:

The study design is a prospective, randomized controlled trial comparing extended elbow and flexed elbow casting. This study design will provide the highest quality evidence to investigate our primary hypothesis that extended elbow casting for proximal both bone forearm fractures will result in less loss of fracture alignment. The study population eligible for screening will be patients with open growth plates and both bone forearm fractures.

  • Condition or Disease:Fracture;Elbow
  • Intervention/Treatment: Other: Cast
  • Phase: N/A
Detailed Description

Guardians of patients will be approached for informed consent as soon as is feasible following determination of eligibility. Injury characteristics will be obtained from the enrolling physician and the participant's medical record. Participants will be prospectively followed at 2, 4, 6, and 24 weeks post casting. All follow-ups will occur in person in clinic and will consist of radiographs, a clinical examination and a brief interview. The follow up time points and radiographs are all part of standard clinical care. The 24 week follow up visit is an optional clinical care visit. Study duration: 48 months; 40 month enrollment period, 6 month patient follow up and 2 month data analysis period Sample size: 88 patients will be consented per arm. Questionnaires: All questionnaires will take approximately 10 minutes total of the family's time. And all questionnaires for done solely for research purposes. Treatment Crossover Cross over from one treatment arm to another should be rare. Cross over should only occur because of poor cast tolerance or inability to maintain reduction in one position vs. another. If the extension cast is unsatisfactory to the caregivers/guardians or patients they may be converted to a flexed elbow cast. These study participants will remain in the study and be included in an intention-to-treat manner in the final analysis. To streamline the ease of randomization in a busy department like the ED, patients with an even medical record number will be enrolled in the extended elbow cast and all odd medical record number patients will be enrolled in the flexed elbow cast. All CRFs will be pre-labeled with a study ID. The research staff will then record the study ID on the paper log that is locked in the ED cabinet. The consents/assents and the eligibility checklist will be stored in a separate folder in the ED cabinet and picked up weekly by the study coordinator who will then store the consents/assents and eligibility checklist of enrolled patients in a locked filing cabinet in their Dept. of Ortho office. All study visits coincide with regular clinic follow up. The 5 month visits is an optional clinic visit. The Demographic questionnaire (CRF 001) will be given to them at the first clinic visit. The family will be asked verbally for responses to CRF 003 regarding cast and patient experience at every clinic visit. The rest of the CRFs will be completed by study staff regarding condition of cast (CRF003), CRF002 deals with the alignment of both forearm bones via the radiograph, and CRF004 is the elbow motion evaluation done by the study staff. CRF004 is a formal measurement using a goniometer (protractor), whereas the clinical standard of care is visual assessment without the goniometer.

Arms and interventions
Arm Intervention/treatment

Outcome Measures
  • Primary Outcome Measures: 1. Alignment [ Time Frame: 6 weeks ]
    To compare the proportion of proximal both bone forearm fractures that have lost alignment within 6 weeks in patients treated in a flexed elbow cast compared to those treated in an extended elbow cast.
  • Secondary Outcome Measures: 1. Complication Rate [ Time Frame: approximately 24 weeks ]
    To compare cast complication rate between those treated in cast with elbow in flexion compared to those treated with elbow in extension.
  • 2. Range of Motion [ Time Frame: 6 weeks and 24 weeks ]
    To compare elbow range of motion at 6 weeks and 24 weeks post-treatment between patients treated in cast with elbow in flexion compared to those treated with elbow in extension
  • 3. Caregiver Satisfaction Scores [ Time Frame: 6 weeks ]
    Overall condition and satisfaction of patient's cast. Measured by: excellent, good, average, below average, or poor.
