they my firm said max 2 yrs for litigation?

I am a long time practicing personal injury attorney and am not sure what you are seeking advice on. The short answer is yes, you can take the case to trial, but it may not  be in your lawyers control; so you need to understand why the case is being continued. You have not given me any understanding of the issues, which I am sure are complex, to give you even general advice or guidance. Do you know why the insurance company is not making you any offer? Do you know why the case keeps getting continued? You clearly have serious injuries, but your lawyer is the person who can best advise you what is going on. For all I know the case is getting continued because you are preparing for more surgery, or your lawyer is hesitant to try to case because you have a long standing pre-accident history of similar medical problems and/or very difficult liability. It could be that the other side had a conflict with experts they need at trial. Significant injury cases are very complex, with multiple issues to be considered.  No lawyer on this listserve will be in a position to question what your lawyer is doing, without a complete understanding of your case. However, I am happy to give you general advice or explanations of issues if you want to give me more specific information.  Good luck
