Evaluation of coagulation is vital in the care of the orthopaedic patients, particularly in the subspecialties of trauma, spine, arthroplasty, and revision surgery resulting from blood loss and coagulopathies. Although conventional tests (prothrombin time/international normalized ratio, activated partial thromboplastin time, platelet count, and fibrinogen) are most commonly used, others like thromboelastography (TEG) are also available to the orthopaedic surgeons. TEG is a blood test developed in the 1950s, which provides a snapshot of a patient's coagulation profile by evaluating clot formation and lysis. Recently, TEG has been used to assess traumatic coagulopathy. The coagulation parameters measured by the TEG are reaction time (Rtime), time to reach a certain clot strength (K-value), speed of fibrin build up (a-angle), maximum clot amplitude, and percentage decrease of clot in 30 minutes (LY30). Using these values, traumatologists have developed a better, faster, and more accurate overview of a patient's resuscitation and more successfully direct blood product use. However, many orthopaedic surgeons-despite performing surgical procedures that risk notable blood loss and postoperative clotting complications-are unaware of the existence of the TEG blood test and the critical information it provides. Increasing awareness of the TEG among orthopaedic surgeons could have a notable effect on numerous aspects of musculoskeletal care.

Case: A 65-year-old man previously treated by intramedullary nailing for a left tibial shaft fracture presented 6 years later with an open refracture of his left tibia after a motorcycle accident. Treatment required extraction of the bent nail before revision nailing. Conclusions: Extraction of deformed intramedullary devices is a skill that will continue to be demanded of orthopaedic surgeons. In this case, standard extraction though the entry point proved successful. Standard extraction offers the safest form of removal and should be contemplated before considering more morbid methods of extraction while examining the fracture's morphology and the device's deformity.
