ResultsĪ life-size phantom of the glenohumeral joint was constructed. CT arthrographic imaging of the phantom was also performed. Fluoroscopically-guided shoulder arthrography was performed using anterior, posterior, and rotator interval approaches. The joint was stabilized inside the mold, and the surrounding soft tissues were cast in silicone of varying densities. A polyamide mold of the skin was printed using selective laser sintering. The capsule was secured to the humeral head and glenoid to create a sealed intra-articular space.

The joint capsule was 3D printed with rubber-like TangoPlus material, using PolyJet technology. The osseous structures were 3D-printed in gypsum, a fluoroscopically radiopaque mineral, using binder jet technology. The osseous structures, intra-articular space and skin surface of the shoulder were digitally extracted as separate 3D meshes from a normal CT arthrogram of the shoulder, using commercially available software. To describe the methodology of constructing a three-dimensional (3D) printed model of the glenohumeral joint, to serve as an interventional phantom for fluoroscopy-guided shoulder arthrography training.
