drawer test


Also found in: Wikipedia.

draw·er sign

in a knee examination, the forward or backward sliding of the tibia under applied stress, which indicates laxity or tear of the anterior (forward slide) or posterior (backward slide) cruciate ligament of the knee.
Synonym(s): drawer test
A test used to evaluate anterior or posterior shoulder instability
Method Medial compression of the humerus into the glenoid comprises the 'load' portion, while translating the humerus anteriorly or posteriorly comprises the 'shift'

draw·er sign

(drōr sīn)
In a knee examination, abnormal forward or backward sliding of the tibia with respect to the femur indicating laxity or tear of the anterior (forward slide) or posterior (backward slide) cruciate ligament of the knee.
Synonym(s): drawer test.

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.

The knee joints were still swollen, and the endpoint by manual posterior drawer test was not detected.
Preoperative examinations, including Anterior drawer test, Lachman test, Pivot-shift test were carried out for all patients.
We used Lachman test and anterior drawer test for knee laxity rate.
The results of physical examination were as follows: anterior drawer test, valgus stress test at 30 flexion, and McMurray findings were positive; posterior drawer test, varus stress test, external rotation recurvation test, quadriceps active test, posterolateral drawer test, and dial test were negative.
Outcome was measured using Lysholm knee score, IKDC Score, Anterior drawer test, Range of motion of the knee joint and Quadriceps power of ipsilateral knee.
The valgus and varus stress tests, anterior drawer test, pivot-shift test, and posterior drawer test had negative results, indicating an absence of ligamentous abnormalities.
Definitive diagnosis of a suspected ACL rupture can be achieved by a so-called Drawer Test.
As with an anterior drawer test of the knee, the radius and ulna are distracted away from the distal humerus.
Seven of the eight patients were negative on the anterior drawer test after the procedure; five of eight patients had a negative talar tilt test.
After the modified TTA, the cranial drawer test was still positive in all dogs, whereas a negative tibial compression test was observed in nine stifles.
Lachman test: This test is performed in the same way as the anterior drawer test, but with the knee flexed to 20 degrees.
Orthopedic testing such as positive Lachman's and anterior Drawer test, indicating ACL instability, (3) along with appropriate imaging confirm the diagnosis and success of reduction.
