Abstract
OBJECTIVE: To explore the clinical effect of 3D printing combined with framework internal fixation technology on the minimally invasive internal fixation of high complex rib fractures. METHODS: Total 16 patients with high complex rib fractures were included in the study. Before the procedure, the 3D rib model was reconstructed based on the thin-layer chest CT scan. According to the 3D model, the rib locking plate was pre-shaped, and the preoperative planning were made including the direction of the locking plate, the location of each nail hole and the length of the screw. During the operation, the locking plate was inserted from the sternum to the outermost fracture lines of ribs with screws at both ends. In addition, the locking plate was used as the frame to sequentially reduce the middle fracture segment and fix with screws or steel wires. Chest x-rays or chest CT scans after surgery were used to assess the ribs recovery. All patients were routinely given non-steroidal anti-inflammatory drugs (NSAIDS) for analgesia, and the pain level was evaluated using numerical rating scale (NRS). RESULTS: The preoperative planning according to the 3D printed rib model was accurate. The reduction and fixation of each fracture segment were successfully completed through the framework internal fixation technology. No cases of surgical death, and postoperative chest pain was significantly alleviated. Five to 10 months follow up demonstrated neither loosening of screws, nor displacement of fixtures among patients. The lungs of each patients were clear and in good shape. CONCLUSION: The application of 3D printing combined with framework internal fixation technology to the high complex rib fractures is beneficial for restoring the inherent shape of the thoracic cage, which can realize the accurate and individualized treatment as well as reduces the operation difficulty.
