“…On the other hand, the incidence of occurrence of the supernumerary muscle decreases as the incidence of the SAB rises; that is, the sum of the incidence of the SAB and that of the supernumerary muscle should be 56% . The figures for the incidence of occurrence of the SAB reported by Bardeen (1907) and Hasue (1958) are extremely low, compared with ours. Moreover, these investigators paid no attention to the suppernumerary muscle appearing between the adductors brevis and minimus.…”

“…We previously described the characteristics of the RAB in detail (Nakamura et al 1992) and have stated that the RAB is sandwiched by the anterior and posterior branches of the obturator nerve and receives the twigs from the anterior branch at its anterior surface. We stated also that the adductor brevis innervated only by the posterior branch of the obturator nerve, which has been reported by Bardeen, 1907 (5 cases), by Hasue, 1958 (1 case) and by Moghaddam, 1963 (1 case), cannot be regarded as the RAB. Thus, the SAB should be considered to be a complex product formed with the RAB and an unknown fasciculus.…”

“…Before to discussing this, the topographic-anatomical relationship between the posterior branch of the obturator nerve and the adductor minimus must be elucidated first. It has been widely reported that the posterior branch of the obturator nerve emerges into the thigh through the obturator canal, and then runs distally along the anterior surface of the adductors minimus and magnus to give off several twigs to both muscles from their anterior surface (Bailer, 1904; Bardeen, 1907;Frohse & Frânkel, 1913;Braus & Elze, 1960;Tozinbara, 1960;Moghaddam, 1963;Hollinshead, 1974;Williams et al 1989). In the present study, the posterior branch of the obturator nerve was found to run distally along the anterior surfaces of the adductors minimus and magnus in all 100 thighs and to supply the several twigs to the adductor minimus from their anterior surfaces (Figs 5a, b and 6a, b).…”

“…These reports, except that of Frohse Frankel (1913), provide general information on the origin and insertion of the muscle and its adhesion to neighbouring muscles concerned, but they do not address its nerve supply. Some investigators have stated that the adductor brevis usually receives, at its anterior surface, twigs from the anterior branch of the obturator nerve and occasionally receives, at its posterior surface, filament(s) from the posterior branch of the nerve (Bardeen, 1907;Hasue, 1958;Tozinbara, 1960). However, they did not discuss the true nature and mechanism of formation of this dually innervated muscle.…”

Summary: To clarify the true nature and the mechanism of the human adductor brevis (specific adductor brevis, SAB) innervated dually by the anterior and posterior branches of the obturator nerve, we have carried out gross anatomical examination of 100 body halves of 50 adult Japanese cadavers.The SAB was found in 23 of the 100 thighs (23.0%), and its anterior and posterior surfaces received respectively the twigs from the anterior branch of the obturator nerve and the filament(s) from the posterior branch. The filament(s) was either indirectly derived from the medial stratum of the posterior branch through the formation of a common trunk with the twigs distributed in the obturator externus (14/23 thighs, 60.9%) or directly originating in the medial stratum of the posterior branch of the obturator nerve (9/23 thighs, 39.1%). In the close examination of the intramuscular distribution of the nerve to the SAB, the region innervated by the anterior branch of the obturator nerve could cleary be distinguished from that innervated by the posterior branch. The obturator nerve received fibers from L1234 (2/23 thighs) or from L234 (21/23 thighs), and the posterior branch of the obturator nerve ran through the obturator externus (18/23 thighs, 78.3%) or ran over the obturator externus (5/23 thighs, 21.7%), and finally emerged into the thigh.In view of the mode of origin of the filament(s), the structural element of the filament(s), and the pattern of entry of the filament(s) into the SAB, the fasciculus of the SAB, which is innervated by the posterior branch of the obturator nerve, was considered to originate in the obturator externus. Thus, the true nature of the SAB was concluded to be a complex product which was formed by a mechanism in which the fasciculus, which had separated from the obturator externus during the process of ontogeny, fused secondarily to the posterior surface of the regular adductor brevis. From findings in our series of studies, it was estimated that the maximum frequency of occurrence of the SAB could be 56%. Furthermore, from a statistical point of view, the segmental composition or course of the obturator nerve is not considered to be related to either the formation or the incidence of this muscle.
