Unexpected results after sternal reconstruction with plates, cables and cannulated screws

摘要: Objectives During the last decade, various plate fixation systems have been developed for treatment of complicated sternal dehiscence after open-heart surgery. One them is Modular Sternal Cable System© (MSCS), which promises optimal distribution forces along whole sternum by using plates, cannulated screws and cables. However, in comparison with other systems, there a lack outcome data. Methods reconstruction MSCS was performed 11 patients (male n = 10, age 72.0 ± 7.3 years) following cardiac surgery, 73% had history infection. included bilateral longitudinal plating thoracic re-closure 4-9 Patients received postoperative examination, focusing on wound conditions clinical stability. If any suspicion recurrent infection, computed tomographic scans were done early period or long term, order to evaluate bony consolidation integrity osteosynthetic material. Results The mean operation time 165 59 min, intubation 4.7 5.3 min intensive care unit length stay 1 day (median) (range 1-23 days), total hospital 9 days 5-64 days). Operative mortality 0%. patient died 65th non-MSCS-related cause. infection occurred 6 (54.5%) made hardware removal necessary 5 postoperatively (median 14 days) late (1058 In another patient, material removed 715 application due persisting pain. Conclusions A high incidence infections observed implantation MSCS. It may be speculated that design (e.g. absence locking system, large screws) compromises osseous microcirculation, favouring development This should kept mind further systems.
