“…FDM techniques can also be used for disease/injury diagnosis purposes. Frizziero et al (2019) 54 reported the use of computed axial tomography (CAT) data which are converted into 3D-printed models, and these models are used to characterize the anatomical structure of fractures and lesions to provide a complete pre-surgery evaluation.…”

“…Medical images were acquired in the Digital Imaging and Communications in Medicine (DICOM) format and transferred to the 3D-printing POC. Three-dimensional digital reconstruction was achieved through a process of image segmentation and conversion in Standard Triangulation Language (STL) format, using open-source software (3D Slicer) [23], according to a well-established procedure in use at our lab [18,24,25] (Figure 2). In accordance with this procedure, the 3D digital reconstruction of the anatomical region of the patient is analyzed and imported in a virtual working environment (Blender) [26] (Figure 3) able to plan and simulate the correction, to design the patient-specific (PS) implants and/or device and to predict the final outcome.…”

Complex deformities of lower limbs are frequent in children with genetic or metabolic skeletal disorders. Early correction is frequently required, but it is technically difficult and burdened by complications and recurrence. Herein, we described the case of a 7-year-old girl affected by severe bilateral genu varum due to spondyloepiphyseal dysplasia. The patient was treated by patient-specific osteotomies and customized structural wedge allograft using Virtual Surgical Planning (VSP) and 3D-printed patient-specific instrumentation (PSI). The entire process was performed through an in-hospital 3D-printing Point-of-Care (POC). VSP and 3D-printing applied to pediatric orthopedic surgery may allow personalization of corrective osteotomies and customization of structural allografts by using low-cost in-hospital POC. However, optimal and definitive alignment is rarely achieved in such severe deformities in growing skeleton through a single operation.

The study of CAD (computer aided design) modeling, design and manufacturing techniques has undergone a rapid growth over the past decades. In medicine, this development mainly concerned the dental and maxillofacial sectors. Significant progress has also been made in orthopedics with pre-operative CAD simulations, printing of bone models and production of patient-specific instruments. However, the traditional procedure that formulates the surgical plan based exclusively on two-dimensional images and interventions performed without the aid of specific instruments for the patient and is currently the most used surgical technique. The production of custom-made tools for the patient, in fact, is often expensive and its use is limited to a few hospitals. The purpose of this study is to show an innovative and cost-effective procedure aimed at prototyping a custom-made surgical guide for address the cubitus varus deformity on a pediatric patient. The cutting guides were obtained through an additive manufacturing process that starts from the 3D digital model of the patient’s bone and allows to design specific models using Creo Parametric. The result is a tool that adheres perfectly to the patient’s bone and guides the surgeon during the osteotomy procedure. The low cost of the methodology described makes it worth noticing by any health institution.
