Use of Three-Dimensional Printing Technology for Supporting the Hip Reconstruction Surgery in Paediatric Patients

Abstract

The use of three-dimensional (3D) printed patient-specific anatomical models is nowadays a viable strategy for improving surgical outcome in medicine. In adult surgery, 3D printing technology is commonly studied, but its use in paediatric surgery is still under development. This work presents the implementation of 3D printing technology in Orthopaedic department of the paediatric hospital “Santobono-Pausilipon” in Naples by producing 3D printed anatomical models of paediatric patients. The 3D printed models produced were used for the training of the surgical team during the preoperative planning and for carrying out a surgical simulation. The anatomical models are designed in compliance with the current European Medical Devices regulation and following the already existing guidelines in literature. The impact of the 3D printed anatomical models used, a total of seven printed anatomical models based on four patients, is then evaluated throughout a questionnaire proposed to the surgical team, composed by eight paediatric orthopaedic surgeons. Surgeons answered to a total of ten questions, six scale-based questions and four free-text questions. Results obtained from the questionnaires highlighted how 3D printed anatomical models can lead to a better understating of the treated pathologies, carrying relevant improvements in both the surgical team training and the surgical outcome.
