Which of the following is NOT considered a complication of crush injuries?

Crush injuries can lead to a variety of serious complications due to the significant force applied to the tissues, muscles, and structures within the affected area. Among the other options provided, compression of tissues, fractures, and compartment syndrome are all recognized complications that can arise from such injuries.

When tissues are compressed for a prolonged period, it can lead to ischemia (lack of blood flow) and subsequent tissue damage, which is a common outcome of crush injuries. Fractures may occur as a direct result of the crushing force impacting the bone structures. Additionally, compartment syndrome is a life-threatening condition that can develop when swelling occurs within a confined space in the body, such as a muscle compartment, leading to increased pressure, decreased blood flow, and potential muscle and nerve damage.

In contrast, the choice indicating "no injury at all" directly contradicts the definition and understanding of crush injuries. Such injuries by their very nature involve some level of damage or trauma to the affected area. Therefore, this choice is accurate in identifying what does not align with the known complications associated with crush injuries.
