Fixation of a pubic bone fracture with an implant made by 3D printing

Introduction: The complex anatomy of the anterior pelvic ring and the mechanics of load distribution impose specific requirements for implants. 3D printing technologies make it possible to produce implants with specified parameters in a short time. While additive technologies are widely used in orthopedics, experience in patients with fractures of the pelvic ring is limited. Objective: To present the clinical case of using a 3D-printed implant for fixation of a pubic bone fracture.Materials and methods: A clinical case of a 42-year-old patient treated with a catatrauma as a result of a fall from the third floor. On admission, treatment was initiated using the ATLS protocol. Diagnosed with Fracture of the pelvic bones AO / OTA 61-B2.1c, 61-A2.1. Alcoholic intoxication. Chronic viral hepatitisC. Hospitalized in the intensive care unit. After 8 days from the moment of injury, the final fixation of the pubic bone was performed with a 3D-printed nail, osteosynthesis of the lateral sacral masses with a 7.3 mm cannulated screw. On the first day after the operation, the patient was activated with crutches. Early postoperative period without complications.Conclusion: Additive technologies facilitate the development of new implants and their introduction into clinical practice. The proposed rod makes it possible to successfully stabilize bone fragments of the pubic bones. The use of additive technologies for fractures of the pelvic bones is of practical importance, which requires further study.
