a. There is a loss of limb function. The athlete usually complains of having fallen or of having received a severe blow to a particular joint and then suddenly being unable to move the part.

b. Deformity is almost always apparent. Since the deformity can often be obscured by heavy musculature, it is important for the examiner to palpate the injured site to determine the loss of normal body contour. Comparison of the injured side with its normal counterpart often reveals distortions.

c. Swelling and point tenderness are immediately present.
