Isolated acute hip adductor brevis strain.

Acute muscle strain occurs as a result of an eccentric contraction that exceeds the biomechanical strength of the musculotendinous junction of a single muscle within a synergistic group. To date, only the (hip) adductor longus was shown to sustain this type of injury. In this case report, I describe the first published example of an magnetic resonance imaging (MRI)-documented acute hip adductor brevis strain.
