In the “analysis3D printingmachineIn the report of 5 cases of multiple rib fracture surgery advantages, Chinese researchers from Shijiazhuang Third Hospital explored better ways to treat rib fractures. This is one of the most common types of fractures, accounting for nearly 80% of chest injuries. %. In this study, they examined 5 patients with multiple rib fractures, and established a three-dimensional model of the ribs, as well as a pre-formed titanium alloy rib locking plate.
Studies in the past few years have shown that for patients with multiple rib fractures, surgical intervention can often achieve better results. However, there are complex considerations when dealing with fracture sites, which are more unique and present challenges for the surgeon to decide where to make the incision.This is3D printingThe advantage of the model is that it can better plan the operation.
The study was conducted from January 2017 to August 2018. All 5 patients were examined. After CT scans and confirmed fractures, each patient passed3D printingThe machine customizes the rib locking plate for each patient.
Patient 1: A 61-year-old male.3D printingThe model helps to create a double-ribbed titanium alloy frame locking plate, which is placed on the surface of the third rib and fully coincides with the front and rear ends of the third rib.

Patient 1 (a) preoperative scan showed long comminuted fractures of 3 and 4 ribs.Using CT-based thin-slice scan3D printingTechnology, made the preoperative 3 and 4 rib models. c, d restore fracture morphology;3D printingThe model is spliced, and the titanium alloy ribbed plate is formed according to the pattern. On postoperative review, the shape of the internal fixator was intact, and the shape of the contralateral rib was completely symmetrical to the preoperative image.
Patient 2: A 57-year-old male. With multiple fractures of the left rib, the surgeon decided to fix the inner end of the locking plate to the sternum and the outer end to the rib.
