Hand injury without any deficit: Is systematic surgical exploration justified?

Abstract

Out of 100,000 inhabitants, 700 to 4000 suffer a hand wound each year. Numerous hand wounds that may not have a clinically evaluated deficit, actually have damage to a major structure after surgical exploration in the operating room (OR). The aim of our study was to evaluate the incidence of major structure damage within a population of patients presenting a hand wound with no deficit on the clinical examination. Every patient older than 12 years, consulting for a wound deeper than the dermis with no clinical signs of major structure damage underwent surgical treatment and exploration of the wound under regional anesthesia in the OR. After each surgery, the surgeon filled out an anonymous study form describing the wound characteristics and the potential findings of major structure damage. Of the 145 wounds with normal clinical examination, we found that 58.6% had a major structure damaged. Given that damage to any major structure in the hand can lead to functional sequela, and the fact that a well-conducted clinical examination by a qualified hand surgeon is not sufficient to eliminate major structure damage, we recommend systematic surgical exploration of hand wounds, even when no clinical deficit is evident.
