Wang Q, et al. - Experts evaluated the clinical efficacy of 3D printing fracture models to assist in creating pre-contoured plates to treat proximal third humeral shaft fractures. They retrospectively identified proximal third humeral shaft fractures treated between February 2012 and February 2015. In shortening the duration of surgery, reducing blood loss volume, and in making this surgical procedure easier for less-experienced surgeons, 3D printing technique turned out to be helpful.
