Director Qu Wenqing attached great importance to it and made detailed preoperative preparations for the patient. The foot and ankle surgery team worked closely with him.3DThe R&D team of the printing center made many careful designs on details such as the shape of the prosthesis, surface smoothness and ligament attachment points, and spent half a month customizing the prosthesis titanium alloy talar for the patient.
