![]() Then, he underwent serial check-ups in which the effectiveness and appropriateness of the treatment were clinically monitored and evaluated using subjective scales: visual analogue scale and patient-rated wrist evaluation. The child, immobilized by a temporary splint, wore his 3D device after 12/24 h. The flow chart includes clinical and radiological examinations of every enrolled child, collecting information required by the program and its elaboration by bioengineers, and then transfer of the results to 3D printers. We chose to treat nondisplaced metaphyseal distal fractures of the radius in 18 patients enrolled from January 2017 to November 2017. We decided to use a model with a double-shell design and holes varying in width to ensure complete ventilation and lightness of the device. The phase of software elaboration requires close cooperation among physicians and engineers. The operative phase was performed by two 3D printers and a scanner in the bioengineering laboratory of the hospital's outpatient area. This procedure had already been performed at Level II, Trauma Center, Campania Region, Orthopaedic Division of Santobono Children's Hospital, Naples, Italy. We describe the manufacturing process of the 3D device in place of the plaster cast usually applied to a child 48/72 h after the access to the Trauma Center Traumatology Hub. The aim of this study is to implement the clinical use of the three-dimensional (3D) design and printing technology in pediatric pathologies requiring immobilization.
