D, Deep femoral artery; De, descending circumflex femoral artery; F, femoral artery; L, lateral circumflex femoral artery; M, medial circumflex femoral artery.
Types 1, 1 a, 1 b (upper row, left to right); types 1c, 2, 3 (middle row, left to right); and types 4, 5, 6 (lower row, left to right).
Type 4 is the variety of origin commonly described in the textbooks. There is evidently a tendency for this form of origin to appear more often in the left thigh than in the right in the male but not the female.
Adachi's statistical tables for right and left sides of the bodies of Japanese are based upon a population of about three-quarters males and one-quarter females. Our [Williams et al] findings agree with his: in that type 4 (Adachi's truncus profundocircumflexus perfectus) is oftener seen on the left than on the right; in that type 3 (Adachi's truncus profundo-circumflexus medialis) is more frequently a right-sided than a left-sided phenomenon; there may be a difference as to sidedness in the occurrence of type 2 (Adachi's truncus profundo-circumflexus lateralis).
