The Lachman test is used by the examiner to determine the extent of a patient’s toe injury at the level of the metatarsal phalangeal joint (fig 1). Step 1: Place the foot in a neutral position. Step 2: Place one hand on the distal aspect of the metatarsal neck and place the second hand on the base of the proximal phalanx. Step 3: With the first hand still on the distal aspect of the metatarsal, pull dosraly on the toe. Step 4: Repeat on the opposite foot and compare the displacement of the toe. An increase in the displacement of the toe of the injured foot is a positive sign of a plantar plate and/or capsular ligament tear.
