Background: Three-dimensional (3D) printed orthoses are being investigated as potential replacements for conventional casts for fracture treatment. 3D-printed casts could improve patient comfort and outcomes, as well as reduce complications like neuropraxia or cutaneous disease. Dimensions necessary to create such casts could be obtained in an easy, quick and non-invasive way with 3D surface scanner. The objective was to validate the Structure Sensor 3D scanner for forearm measurements.
Methods: The Structure Sensor 3D scanner was used to take scans of both forearms in 24 healthy volunteers. The measurements deducted from these scans were compared with the golden standard; direct circumference measurements with a measuring tape and volume measurements using water displacement volumetry. The interrater reliability and accuracy were calculated.
Results: The interrater reliability was 0.992 (p < 0.001) and 0.952 (p < 0.001) for circumference and volume measurements respectively. The dimensions obtained from with the 3D scanner were strongly correlated with their direct counterparts r = 0.977 (p < 0.001) and r = 0.893 (p < 0.001).
Conclusion: Based on the results from this study, the Structure Sensor 3D scanner has shown to be a reliable method for reproducible data on the forearm dimensions. Further research is necessary to investigate the use of these 3D scans in the process of creating 3D printed patient-specific orthoses in the treatment of DRF.

The association of right ventricular outflow tract obstruction with complete atrioventricular septal defect is rare and poses surgical challenge at the time of intracardiac repair. We report here-in a 30-months-old female child diagnosed with severe right ventricular outflow tract obstruction, complete atrioventricular septal defect and severe left atrioventricular valvar regurgitation undergoing successful pulmonary valvotomy, resection of the right ventricular outflow tract with reconstruction of the complete atrioventricular septal defect by two-patch technique. The pulmonary valve ring was sutured directly. Postoperative period was uneventful.
