Abstract:
The lumbar plexus was investigated on 320 sides of Chinese adults. Using the furcal nerve as a guide, the author divided the plexus into eight types. It was found that the quantity of fibers of the furcal nerve added to the lumbar plexus was more than that to the sacral plexus. This type occurred in 69.37% and was classified as Type Ⅰ.The types of composition of the nerves and the quantity of fibers which joined to form each of these nerves of the plexus have been studied.The common types of nerve constitution were as follows: the femoral nerve was composed of L_(1-4) (73.75%); the obturator nerve, of L_(2-4) (84.06%); the femoral lateral cutaneous nerve, of L_(1-2) (40.63%) or L_(2-3) (39.37%) the genito-femoral nerve, of L_(1-2)(72.19%). According to the condition of fusion or division of the iliohypogastric and ilioin-guinal nerves, three types may be classified, namely, the separate trunk type--36.87%,the common trunk type--50.63%, and the complex type--12.5%. The terminology of the accessory femoral nerve and the accessory obturator nerve has been discussed. In this series, the frequency of the accessory femoral nerve was 7.5%, while that of the accessory obturator nerve was 3.44%.
