An Often Easily Missed Injury in the Presence of Orthopaedic Trauma: A Case Series of Derived Injury

Derived disaster is a common concept in emergencies such as earthquakes. With the progress of society, the incidence of fractures caused by high‐energy trauma has increased year by year. After the first injury, the possibility of derived injury caused by the original injury also increases rapidly. Orthopaedic surgeons, especially trauma orthopaedic surgeons, lack sufficient understanding and recognition of this kind of injury. The purpose of this article is to present a case series of an often missed injury pattern that is associated with an original injury. The diagnosis of derived injury may go unrecognized in a considerable number of cases and delayed treatment decreases the success rate of soft tissue repairing; therefore, a high index of suspicion and a proper early diagnosis is of paramount importance. We also describe the current surgical management used by the authors, and propose the concept of “derived injury”, studying its clinical significance in traumatic orthopaedics.
