Case History Four
This case history is about a football player who suffers from a muscle disorder. The
muscle disorder he most likely suffers from is referred to as, Rhabdomyolysis. Rhabdomyolysis
is always triggered by a muscle injury. Rhabdomyolysis is a condition in which skeletal muscle
is broken down, releasing muscle enzymes and electrolytes from inside the muscle cells.
Occurring during a molecular and cellular level of Rhabdomyolysis is ...view middle of the document...
There are many different causes leading to Rhabdomyolysis and they can be classified
into two categories known as environmental causes and internal causes. Two environmental
causes are: The use of alcohol or illegal drugs such as heroin, cocaine or amphetamines and a
crush injury such as from an auto accident, fall, or building collapse. Two internal causes are:
Extreme muscle strain, especially in someone who is an untrained athlete and also blocked blood
vessels can cause this along with diseases of the muscles (myopathy) such as congenital muscle
enzyme deficiency or Duchenne's muscular dystrophy. Rhabdomyolysis is treatable and patients
may recover quickly if the disease is caught in its early stages. Treatment with intravenous (IV)
fluids helps maintain urine production and prevent kidney failure. Rarely, dialysis treatment may
be needed to help your kidneys filter waste products while they are recovering. Management of
electrolyte abnormalities (potassium, calcium and phosphorus) helps protect your heart and other
organs. You may also need a surgical procedure (fasciotomy) to relieve tension or pressure and
loss of circulation if compartment syndrome threatens muscle death or nerve damage. In some
cases, you may need to be in the intensive care unit (ICU) to allow close monitoring.
