My Father had CABG (Bypass) surgery in Feb 2015, his heart function has improved over time but as he is a diabetic he had pus cell formation in the chest stitch area, which eventually turned into osteomyelitis, he has had two debridement surgeries to remove the affected areas and in the recent one he had his 4 ribs removed, that makes it a total of 5 removed ribs. Does anyone have an idea what are the methods used to support the areas where the ribs have been removed? From what I know there is some kind of a mesh. Does anyone have any idea about that and what will happen if no support is provided?
