The ever-present question to be answered in personal injury cases, other than liability of course, is the measure of damages to which the plaintiff is entitled. Where the plaintiff has been left with a permanent total, or permanent partial disability, such disability must be properly evaluated and transformed into an element of a money award for damages in order that adequate compensation will be received by the injured party. The problem of evaluating a permanent disability of the arm or hand is as medically complex as the multiplicity of functions which the member performs.
