Individualized 3D printing-assisted repair and reconstruction of neoplastic bone defects at irregular bone sites: Exploration and practice in the treatment of scapular aneurysmal bone cysts

The irregular anatomical shape and complex structures of irregular bones make it more difficult to repair and reconstruct bone defects in irregular bones than in the long bones of the extremities. Three-dimensional (3D) printing technology can help to overcome the technical limitations of irregular bone repair by generating simulations that enable structural integration of the lesion area and bone structure of the donor site in all directions and at multiple angles.
