Objective: To describe the use of three-dimensional prototyping or rapid prototyping in acrylic resin to create synthetic three-dimensional models in order to promote the understanding of bone deformities of the shoulder.
Methods: Five patients were analyzed between ages of 11 and 73 years old, treated between 2008 and 2013 with glenohumeral deformities that required a more thorough review of the anatomical alterations, for whom three-dimensional prototyping was performed.
Results: Patient 1 was treated conservatively and is awaiting humeral head arthroplasty if symptoms get worse.
