Canalis cruropopliteus - the overlooked canal of Wenzel Gruber.

It is widely known that the popliteal fossa and the lower leg are connected by a canal, containing the neuro-vascular bundle to the posterior leg region, containing the tibial nerve and the posterior tibial artery and veins. The existence of this canal has not been duly recognized in literature, even though it has been named by Wenzel Gruber in 1871, and its contents, walls, entrance, and exits have been extensively described by him in 1878. In the present paper, we would like to pay a homage to the work of this prominent anatomist, which retains its significance for contemporary surgical practice. The cruropopliteal canal, canalis cruropopliteus, as named by him, and having been assigned a multitude of terms in practice, deserves to regain its eponymous name - Gruber's canal. The history, and the anatomy with its clinical implications are discussed herein. We hereby recommend that the original name of this canal be included in anatomical textbooks and specialized literature.
