drawer test

(dro'(e)r)
Determination of the instability of ligaments by forcibly displacing one bone or structure relative to another.

1. Assessment of the cruciate ligament(s) of the knee. The knee is flexed to 90° with the foot stabilized on the examination table. The examiner applies an anterior, then a posterior, force against the upper tibia, perpendicular to the long axis of the leg. An increased glide, anterior or posterior, of the tibia is caused by rupture of the anterior or posterior cruciate ligament, respectively.

2. Assessment of the anterior talofibular ligament of the ankle. The foot is placed in its neutral position, the knee is flexed to a minimum of 20° to release the tension of the gastrocnemius muscle, and the tibia is stabilized. The examiner cups the posterior and plantar surface of the calcaneus and draws the foot forward, observing for increased displacement of the lateral foot and talus relative to the opposite extremity. These findings suggest rupture of the ligament. Synonym: drawer sign.
