Videos: Diagnostic Tests

We occasionally make reference to additional tests to determine the type of wrist injury you may have.  

There are three ways to assess wrist stability: the weight bearing test at 90 degrees, the modified weight bearing test at 45 degrees and the modified grip test at 30 degrees. These three test are important in the understanding of the wrist

The modified grip weight test is valuable in understanding the weight load tolerance of the wrist. This test requires grip strength and wrist extension at 30 degrees.
The 45 degree angle is harder to perform, and drops weight bearing tolerance 30% in normal healthy wrists. This position does not require full wrist extension and is valuable in our assessments.
This test is used to determine hamate fractures.
