[Mathematical considerations on nerve sutures]

Assuming that in nerve suture all proximal nerve fiber ends are connected to distal nerve fiber ends the mathematical probability of useful connections in a mixed nerve is evaluated. A connection between two motor fiber ends or between two sensory fiber ends is regarded as useful, whereas a connection between one motor end one sensory end is useless. It can be demonstrated, therefore, that the number of fiber ends, i. e. sensory or motor, which pre-dominate have the better chance for useful connections.
