|
The anterior compartment is extremely __, which leaves __ room for swelling.
|
The anterior compartment is extremely RIGID, which leaves LITTLE room for swelling.
|
|
|
Acute Anterior Compartment Syndrome Characteristics
|
In Anterior Compartment:
not a lot of room for swelling- swelling after trauma causes decreased O2 to foot foot turns black and blue 4 h. to relieve pressure before amputation becomes necessary |
|
|
External Compartment Syndrome Characteristics
|
External Compartment Syndrome:
same as acute, but ... occurs w/ running & after running symptoms go away no trauma to extremity |
|
