overuse injury
occurs when muscles become fatigued and unable to absorb shock
diagnosis–x-ray (can be neg), MRI, bone scan.
treatment = rest.
medial tibial syndrome
most common site is distal one-third of the medial border of the tibia. not well understood.
Treatment is rest.
compartment syndrome
increased pressure within a limited space that compromises the circulation and function of the tissue within that space.
ischemia and necrosis
True orthopedic emergency.
Causes of compartment syndrome
fractures, blunt trauma, cast, burns/electrical, exertion, gunshot, hemophiliac, bite.
pathophysiology of compartment syndrome
normal tissue pressure: 0-4mm Hg (8-10 with exertion).
The most sensitive tissue to increased tissue pressure is what?
nerve tissue
after 8 hours irreversible changes occure
Treatment for accute compartment syndrome
fasciotomy
