Three-dimensional (3D) printing technology has the advantages of fast design and fabrication in clinical orthopedics. This study proposed the application of 3D-printed personalized reverse shoulder prosthesis in a reverse total shoulder arthroplasty for a patient with tuberculosis of the shoulder joint. Traditional and personalized shoulder prostheses were compared and studied. The mechanical simulation analysis was conducted on the individualized prosthesis and scapula. A personalized reverse total shoulder prosthesis was fabricated by 3D printing technology. Finite element analyses were conducted for implantation of traditional and personalized prostheses. The numerical results show that the maximum equivalent stress of screws inserted into bone tissue is 43.23 MPa in the personalized prosthesis. But in traditional prostheses, the maximum equivalent stress of screws performing the same function is 246.50 MPa. The structural advantages of the personalized prosthesis effectively reduce the local pressure of the screws to ensure the safety and effectiveness of the material during service. At the same time, the scapula paired with the personalized prosthesis also shown a smaller mean equivalent stress that can reduce patient stress. The postoperative evaluation of implant stability and patient status was good. The results indicated that 3D printing technology has important application value in orthopedic surgery.
