The adductors are composed primarily of superficial (pectineus, gracilis, and adductor longus), middle (adductor brevis), and deep (adductor magnus) muscle structures [26] (Fig. 14A,C). The adductor magnus has anterior and

Fig. 14. Axial T1-weighted images of proximal thighs in professional football player with acute groin pain on the left. The annotated right side (A) shows normal anatomy of the adductor muscle group: al, adductor longus; ab, adductor brevis; am, adductor magnus. The black arrows show the normal myotendinous junction of the adductor longus. The white arrows depict adductor brevis myotendinous junction and the white arrowhead shows myotendinous junction of the gracilis. (B) Edema of myotendinous strain of adductor longus on fluid-sensitive axial images. (C) Additional anatomy more distally of mid thigh. s, sartorius; g, gracilis.

posterior heads. The anterior head of the adductor magnus (as well as other muscles in the adductor group) receives innervation by the obturator nerve. The posterior head is innervated by branch of sciatic nerve like other hamstrings and functionally resembles a hamstring muscle. The adductor head of the magnus has a proximal attachment on the ischial ramus and inserts distally along the entire linea aspera. The posterior head has proximal attachment on the ischial tuberosity anteroinferiorly and distally attaches on the medial distal femur on the adductor tubercle.

The adductor brevis proximally attaches to the anterior surface of inferior pubic ramus and distally attaches to the proximal third of the line aspera. The adductor longus arises from anterior surface of the body of pubis and inserts distally on the middle third of the linea aspera. The gracilis arises on the anterior aspect of the lower body of the pubis and inferior ramus and inserts on the tibia with the tendons of the pes anserine.
