Usually, the most serious complication for crush injuries is to cause osteo-fascial compartment syndrome, which is very serious. Once discovered, osteo-fascial compartment syndrome requires active symptomatic treatment. Otherwise, it can easily cause necrosis of the distal end at a later stage, which is very dangerous. Therefore, it is important to pay attention to the blood flow, sensation, and temperature of the distal end of the crush injury to rule out the presence of osteo-fascial compartment syndrome. If the patient presents with a high degree of local swelling and very severe pain with passive movement, active movement dysfunction, decreased arterial pulsation, increased skin temperature, and sensory numbness. It is necessary to actively treat the patient with incisional decompression surgery, otherwise the consequences are unthinkable.
