Reunification of a split sciatic nerve / 대한해부학회지

ABSTRACT

Sciatic nerve (SN) variaitons can result in interesting clinical presentations. We identified a SN variant that does not fit into preexisting classification schemes. In an adult male cadaver, the SN was found to divide proximally and partly exit through the piriformis muscle. Distal to the piriformis, the two parts of the SN were reunited. Although apparently extremely rare, such a finding should be added to the archives of anatomical variations.
