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.

As with an anterior drawer test of the knee, the radius and ulna are distracted away from the distal humerus.
18) Other tests, including the external rotation recurvatum test, the varus stress test (at 0[degrees] and 30[degrees] flexion), the reverse pivot shift test, the dial test, and the posterolateral drawer test, are described for posterolateral corner of the knee injuries and are not truly specific to the popliteus.
However, their results indicated that under active anterior drawer test with higher loading forces, neither of braces was effective in controlling anterior tibial translation.
pivot shift, Lachman, and anterior drawer tests, are difficult and sometimes impossible to be applied on brace wearing subjects (Baker et al.
Lachman test: This test is performed in the same way as the anterior drawer test, but with the knee flexed to 20 degrees.
The anterior drawer test was of little diagnostic value.
The drawer test is done with the knee at 90[degrees] of flexion and the examiner sitting on the patient's foot.
The posterior drawer test is the most sensitive diagnostic test for PCL injury.
25) In a study evaluating 29 patients treated with this method, all patients demonstrated a significant improvement on KT-1000 testing, in addition to all but one having a negative posterior drawer test posttreatment.
The drawer test at 90[degrees] tests anterior and posterior motion at 90[degrees], assessing relatively less important parts of the ACL and PCL.
To meet the KCMA standards, the cabinets must meet general construction requirements, pass five structural tests, two door operation tests, two drawer tests, and five finish tests.
