Re: thumb amputation
If the nail did not heal itself within the first 6 months, it will always be this way. The reason is because you 'crushed' the matrix which is where the nail palte cells are 'born'. What you have left is the uppermost layer and the lowest layer and nothing in between. The nai plate is formed in three layers, the bottom layer is attached to the nail bed, the center layer gives the nail strength and the upper layer is the portion you can touch that protects the underlying layers. You can have the nail removed by having the remaining portion of the matrix removed (the root) - in your case this would be the best option as long as they completely remove all the root. Once this is done, you will not grow another nail plate at all.
