Development and Pilot Implementation of a 3D Printed Prototype for Surgical Education and Preoperative Planning in Blount's Disease

Abstract

Blount’s disease is a complex pediatric orthopedic disorder characterized by progressive tibial deformities, necessitating precise surgical planning. Traditional imaging techniques often fail to provide a comprehensive assessment. This study explores the role of 3D-printed anatomical models in enhancing surgical planning and medical training, particularly within the Jordan Royal Medical Services. This study focuses on a 12-year-old patient with a severe multiplanar tibial deformity. A 3D model of the patient’s tibia and fibula was generated using CT scan data, segmented via 3D Slicer software, and printed using FormLabs Form 3BL SLA 3D printer. The printed model was utilized in a pediatric orthopedic workshop attended by over 30 surgeons. Seven surgeons responded to the post-workshop survey. It revealed that all participants found the 3D model beneficial for understanding anatomical deformities, enhancing surgical preparedness, and improving procedural accuracy. However, challenges such as cost, material rigidity, and production time were noted as barriers to widespread adoption. Future research should focus on optimizing material properties and reducing costs to facilitate broader implementation in surgical education and planning in Jordan.
