Which complication of musculoskeletal trauma causes the accumulation of nephrotoxic myoglobin?
Cardiogenic shock
Nerve compression syndrome
Rhabdomyolysis
Avascular necrosis
The Correct Answer is C
Rhabdomyolysis is a condition that occurs when skeletal muscle tissue breaks down rapidly due to injury, infection, drug toxicity, or other causes. The breakdown of muscle releases myoglobin, a protein that carries oxygen in muscle cells, into the bloodstream. Myoglobin can damage the kidneys by clogging the renal tubules and causing acute kidney injury. Rhabdomyolysis can also cause electrolyte imbalances, muscle weakness, and compartment syndrome.
