Adductor brevis is the middle of the three short adductors, lying between pectineus (anteriorly) and adductor magnus (posteriorly). The anterior and posterior divisions of the obturator nerve pass anterior and posterior to the adductor brevis respectively, making the muscle a surgical landmark for the two obturator divisions in adductor canal procedures.

It adducts the thigh and assists hip flexion, helping to stabilise the pelvis during walking.
Adductor brevis strain is a common groin injury in football and ice hockey, producing medial thigh pain with resisted adduction, groin squeeze test, and adductor tendon tenderness. MRI distinguishes adductor brevis from adductor longus and gracilis strains by location of the oedema. The obturator nerve relationship to adductor brevis is exploited in obturator nerve block: injection between adductor longus and adductor brevis at the obturator foramen blocks both anterior and posterior divisions.
Eccentric overload of the adductor brevis during kicking and rapid direction changes produces a proximal myotendinous junction tear with medial thigh pain and groin squeeze pain; MRI distinguishes between the three adductor muscles at the musculotendinous origin with treatment including a graduated rehabilitation and sport-specific return-to-play protocol.
