This study covers all information about the sural nerve anatomy published internationally. The coexistence of different and confusing terminologies is pinpointed and adjusted to allow comparison of previous reports and to gain a coordinated data pool of more than 2500 investigated sural nerves. Detailed features are clearly described and summarized, findings from the authors' own prospective dissections complete these data, and the prior existing anatomical confusion is resolved. Finally, clinical implications are described.

Selective nerve transfers of the amputated nerves of the brachial plexus to the remaining stump muscles can create up to six myosignals for intuitive and simultaneous control of the different prosthetic joints. In this way, an efficient and harmonious control of the prosthetic device is possible without the need to change between the different control levels. At the same time, possible neuromas are treated and painless wear of the prosthesis is achieved. Due to the resulting extended use of the prosthetic device, the demands regarding stump quality are increased. Thus, both surgically and by the means of the orthopedic technician a stable stump-socket connection should be achieved to enable optimal prosthetic function.
