Patient-Specific Digital Modeling and 3D Printing for Preoperative Planning in a Pediatric Distal Radius Osteotomy: A Case Report.

Introduction: This case report describes the utilization of patient-specific 3D modeling for the care of a 13-year-old patient with a distal radius malunion and partial growth arrest.

Methods: Patient-specific 3D models of the patient's wrist were created using computed tomography scans. Digital modeling software was used to determine the appropriate orientation of the osteotomy, size and shape of bone graft, and final wrist alignment. The 3D models were used to rehearse the osteotomy preoperatively. Intraoperatively, bone graft was harvested to the planned specifications and the osteotomy was successfully performed followed by stabilization.  Results: Radiographs demonstrated appropriate correction of radial length, alignment, and rotation matching the preoperative 3D model. At final follow-up, the patient demonstrated union of the osteotomy and full recovery with excellent function.

Discussion: Patient-specific 3D modeling and printing provide valuable tools for planning complex surgical cases. Further research is warranted to assess the broader applications of this technology in orthopedic surgery.
