Valgus Stress (Elbow) at 00 |
Examination type |
Ligament Laxity, Joint Instability |
Patient & Body Segment Positioning |
The patient
is sitting upright, with elbow fully extended (0 degrees).
Patient does not resist or assist any movement. |
Examiner Position |
The examiner
should face the patient while standing on the side of the
affected elbow with one hand cupping the elbow (heel of hand on
lateral side of elbow with fingers on medial side) for support
while the other hand is placed at the patient’s wrist to provide
force. |
Performing the Test |
Cup the
posterior aspect of the patients elbow in one hand and hold the
patients wrist in the other. The hand on the elbow will act as
a fulcrum around which the examiner’s other hand will apply.
With the elbow extended to 0 degrees, force the forearm
laterally which will place stress on the medial side of the
elbow. |
Tissues
Being Tested |
Ulnar collateral ligament |
Positive Test |
Lack of a
firm end feel or extra joint opening as compared bilaterally |
Interpretation |
Possible
sprain (stretching or even tear) of the ulnar collateral
ligament |
Common errors in
performing exam |
Not placing
enough force on the elbow; not completely extending the
patient’s elbow to 0 degrees; not comparing bilaterally |
Factors possibly
resulting in misinterpretation |
Athletes who
routinely participate in repetitive overhead activities, such as
baseball pitchers, may show excess laxity in the dominant arm
even with no injury to the ulnar collateral ligament.
