Open Repair of Acute Proximal Adductor Magnus Avulsion

Hip adduction is accomplished through coordinated effort of the adductor magnus, brevis, and longus and the obturator externus and pectineus muscles. Each of these muscles may be injured at its proximal or distal insertion or in its midsubstance. The incidence of injuries to the adductor complex is difficult to determine in sport because of players' underreporting and playing through minor strains. The most commonly injured adductor muscle is the adductor longus muscle. The injury most frequently occurs at the proximal or distal musculotendinous junction, but several case reports of origin and insertional ruptures of the adductor longus exist in the literature. Successful outcomes have been obtained with both operative and nonoperative approaches in these cases. Reports of isolated proximal avulsion of the adductor magnus are less common. This article describes our surgical technique for management of a rare acute proximal adductor magnus avulsion.
