5. Compartment Syndrome A painful condition resulting from the expansion or overgrowth of enclosed tissue (as of a leg muscle) within its anatomical enclosure (as a muscular sheath) producing pressure that interferes with circulation and adversely affects the function and health of the tissue itself. A potentially limb-threatening complication, can be prevented if recognized and treated early. Definition (Merriam-Webster, 2005)

6. Definition • It can result from either internally expanding pressure forces or externally applied forces. • Internal pressureforce causes increased compartment contents and can be caused from hemorrhage or edema. • External pressure causes decreased compartment size and can be caused by a splint, a cast or prolonged compression to an extremity.

8. Diagnosis Compartment Syndrome can be Acute Or Chronic

9. Diagnosis • Chronic Compartment Syndrome • Muscle pain that repeatedly occurs with vigorous exercise and subsides with rest. • The pain worsens as exercise continues, ultimately restricting performance. • There will often be swelling and abnormal sensations in the affected limb during and immediately after exercise. (Sports Injury Bulletin,2007) Clip art derived from Microsoft Office.

10. Diagnosis • Chronic Compartment Syndrome • Can affect athletes of any age. Anyone involved in a lot of running or jumping. • Not exclusive to the lower leg. It can occur in the arm of a weightlifter, sport climber or motorcyclist, the forearm compartment is usually involved. (Sports Injury Bulletin,2007) Clip art derived from Microsoft Office.

11. Acute Compartment Syndrome Different from Chronic in that it does not require exertion of the muscle to incite pain, and the pain does not subside until treated. It can affect any limb or muscle compartment, including the abdomen, but it mainly occurs after trauma to the lower leg. It may take several hours for acute compartment syndrome to develop. Diagnosis (POSNA, 2005)

12. Acute Compartment Syndrome It can by caused by a traumatic injury, such as a fracture of one of the long bones in the body. A badly bruised muscle, as when a motorcycles falls on the leg of the rider or a football player receives a blow to the thigh from another player’s helmet. A complication after surgery. Blockage of circulation, such as from pressure over a blood vessel for too long while asleep. A Crush injury to the foot. Diagnosis (POSNA, 2005) Clip art derived from Microsoft Office.

19. Pathophysiology Clip art derived from Microsoft Office.

20. Pathophysiology Thick layers of tissue called fascia separate groups of muscles in the arms and legs from each other. (Health-care, 2005) Clip art derived from Microsoft Office.

21. Pathophysiology Inside each layer of fascia is a confined space, called a compartment, that includes the muscle tissue, nerves, and blood vessels. The compartment is surrounded by the fascia much like wires surrounded by insulation. (Health-care, 2005)

22. Pathophysiology There are four main compartments in the lower leg and three main compartments in the forearm. (NAON, 2004)

23. Pathophysiology The main compartments in the lower leg are: Anterior compartment Lateral compartment Deep posterior compartment Superficial posterior compartment. Anterior Deep posterior Lateral Superficial posterior (www.nettingimages.com Image used with permission) (NAON, 2004)

24. Pathophysiology Superficial flexor The Main compartments of the forearm are: Superficial flexor Deep Flexor Extensor Extensor Deep Flexor (NAON, 2004) (www.nettingimages.com Image used with permission)

25. Pathophysiology The Fascia surrounding the compartments in the arms and legs, do not expand, so any swelling in a compartment will lead to increased pressure in that compartment, which will compress the muscles, blood vessels, and nerves. (Health-care, 2005)

26. Pathophysiology As nerves in the compartment are compressed, sensory and motor function decrease and severe pain develops. (Health-care, 2005) Clip art derived from Microsoft Office.

27. Pathophysiology When the pressure in the compartments exceeds the capillary pressure of the tissues, perfusion stops and the tissues become ischemic. The ischemia causes fluid shifts and edema, adding to the pressure. (Health-care, 2005)

28. Pathophysiology If ischemia continues, muscle and nerve tissues die, causing permanent loss of function. (Health-care, 2005)

29. Pathophysiology Muscle damage will be irreversible after 4-6 hours of ischemia. Nerve damage will be irreversible after 12-24 hours. (NAON, 2004)

35. The fascia is NOT flexible, that is why you have the increase in pressure in the compartment. Correct Click on star to go to Next Question

36. Quiz How many compartments are there in the lower extremities and forearm? The lower extremities have 6 compartments and the forearms have 12. A The lower extremities have 4 compartments and the forearms has 3 compartments. B C Both have the same number, 3 compartments. D I don’t remember, please link me back to the answer.

40. Signs & Symptoms Clip art derived from Microsoft Office.

41. Signs & Symptoms • Chronic Compartment Syndrome: • Onset of pain and a feeling of “fullness” over the involved compartments. • There may be a feeling of numbness in the legs/feet. • The affected area may feel tight and tense. (Felton, 2003) Clip art derived from Microsoft Office.

42. Chronic Compartment Syndrome: The symptoms occur at the same point of time during exercise. Symptoms are relieved by rest, usually within 20 minutes of exercise, only to reappear with resuming exercise. Signs & Symptoms (Felton, 2003) Clip art derived from Microsoft Office.

43. Acute Compartment Syndrome: Classic sign is PAIN. The pain may be intensely out of proportion to the injury, especially if no bone is broken. Signs & Symptoms (POSNA, 2005) Clip art derived from Microsoft Office.

44. Acute Compartment Syndrome: There may also be a tingling or burning sensation in the muscle. The muscle may feel tight or full. Signs & Symptoms (POSNA, 2005) Clip art derived from Microsoft Office.

45. Acute Compartment Syndrome: If the area becomes numb or paralysis sets in, cell death has begun and efforts to lower the pressure in the compartment may not be successful in restoring function. Signs & Symptoms (POSNA, 2005)

46. Signs & Symptoms Direct measurements of tissue pressure can be obtained using a needle or wick catheter inserted into the muscle compartment. Compartment decompression is recommended when pressures rise to 30 mmHg. This is a more invasive test used to determine the pressure in the compartment. This test is not performed by nursing.
