Event Description
This report is being filed after the review of the following journal article: zhou x, et al. (2021), application of 3d printing and framework internal fixation technology for high complex rib fractures, journal of cardiothoracic surgery, volume 16, number 5, pages 1-6 (china). This study aimed to explore the feasibility and clinical efficacy of pre-shaping locking plates based on 3d printed rib models, as well as the application of framework internal fixation techniques in minimally invasive surgery of high complex rib fractures. From june 2016 to august 2019, 16 patients who underwent surgical treatment of high complex rib fractures were included in the study. There were 12 males and 4 females with a mean age of 50 years (range, 26 to 27 years). The results of multi-slices spiral ct scan were processed. The 3d model fracture was reduced to its pre-injury form shaping the unknown synthes matrixrib locking plate according to the restored rib model, the placement position and the direction of the locking plate, the length and number of screws were recorded and the locking plate was then sterilized prior to use. During the procedure, the unknown synthes matrixrib locking plate was implanted according to the preoperative planning. After the surgery, all patients were given non-steroidal anti-inflammatory drugs (nsaids) for analgesia, and the pain level was evaluated according to the nrs at 10:00 a. M. Every day. Once the nrs score reaches 4 points or less, the analgesic drugs will be stopped. Follow-up were conducted complications were reported as follows: 2 patients had analgesics used again due to worsened chest pain after stopping the drug. 1 stopped analgesic drugs 2 weeks after surgery, whereas another patient did not stop the analgesic drugs until 6 weeks after surgery. This report is for the unknown synthes matrixrib locking plate construct. This is report 1 of 1 for (b)(4).
