Abstract
ObjectiveThree-dimensional printing may play an important role in patients’ education. The objective of this study was to assess the effectiveness of personalized 3D printed models for increasing patient understanding of their medical condition and surgical plan. MethodsForty-five patients with degenerative lumbar diseases were randomized by block design into three groups: educational program presented by CT & MRI imaging (care-as-usual), 3D reconstructions, or personalized 3D printed models. Patients’ level of understanding and satisfaction were evaluated by two questionnaires one day after education. ResultsPatients educated with personalized 3D printed models demonstrated an expanded level of understanding than patients educated with CT & MRI imaging (care-as-usual) (P ＜ 0.05) and 3D reconstructions (P ＜ 0.05). Personalized 3D printed models also resulted in a higher degree of patient satisfaction (P ＜ 0.05). ConclusionsPersonalized 3D printed models and 3D reconstructions can simplify and enhance understanding of lumbar anatomy, physiology, and patients’ disease and surgical plan. Personalized 3D printed models also enhance patients’ subjective satisfaction. Practice implicationsPersonalized 3D printed models for patient education are feasible and could be generalized for degenerative lumbar diseases.
