You say that this injury occured 2.5 years ago. Generally speaking there is a 2 year statute of limitations, or time limit, to file a WC claim in the State of MO. The 2 years begins on the last day that the employer provided benefits i.e. medical care or Lost time benefits, for your father. If no benefits were provided then it would be 2 years from the date of accident. In this case the effect of the employer not filing a Report of Injury with the Division of WC within the proscribed 30 day time period sets off a 1 year penalty and extends the time limit to 3 years!!! So as of today you are still within the time period.
To get started you probably dont need very much documentation from the employer. If there was any paperwork that was filed internally, that can usuallly be obtained by an attorney- however that is usually not a problem. As far as the value of a case, without having more facts, it is almost impossible to give an idea as to how much a case like this is worth. However I will say that based upon your description it sounds like your father definately has permanant disability in the ankle and in the wrist. Also if the emoployer did not appropriately pay your father for any time he was off of work for this injury or time off of work recovering from the surgeries then they would owe him $$$ for that as well.
Also, it is important to note that injuries such as your fathers that require surgery and leave a person with somewhat marked residual disability could result in a settlement or an Award that would allow you to make an additional recovery from the MO Second Injury Fund for the combnation of these injuries with ANY pre existing disability.
Either way, if you decide to call and hire an attorney or not, I would advise that you IMMEDIATLY file a formal Claim for Compensation with the Division of Workers Compensation in order to stop the Statute of Limitations from running, and potentially barring your father from ever being able to file a claim for this injury.
Hope this Helps.
