Treatment recommend for cut finger.

Hi sir/madam.  I'm looking for some recommendations/suggestions for Mother 58/F. Kindly help me through your valuable suggestions/recommendations. I'll explain my case below. Case: My mom met with an accident while she was involved in cooking process. She met accident while operating mixer, her index finger cut by half. As it was an accident we immediately rushed to hospital with basic emergency measures such as placing finger in ice bag etc. At hospital asusual they said it can't be fixed as the cut part of the finger has damaged. But I had false hope that they'll fix it by microsurgery. To my fate, it remained false. Now surgery has been done and her index finger is amputated. At present what can be done. I'm much worried to see my mom's present condition. I've some basic knowledge about prosthetic surgery, finger replacement surgery. As of now I don't know how to approach. Kindly pour your suggestions/recommendations. Approx Price for such surgery. Thanks in advance - Anand
