crush syndrome

(krŭsh) The tissue damage and systemic effects of prolonged traumatic muscle compression. Crushing injuries may cause compartment syndromes, muscle necrosis, and leakage of muscle cell contents into the systemic circulation, especially after blood flow is restored to damaged tissues. Kidney failure may occur when myoglobin released from injured muscles blocks renal tubules. Electrolyte and acid base disturbances are common. Treatment may include local surgical care, metabolic support, hydration, and alkalinization of the urine. SEE: renal failure, acute; reperfusion; rhabdomyolysis.

crust, crusta

(krŭst) [L. crusta] 1. Dried serum, pus, or blood on the skin surface. Crusts are seen in diseases in which the skin weeps, such as eczema, impetigo, and seborrhea. They are often yellow-brown, dirty cream- or honey-colored. 2. An outer covering or coat.

crutch

(krŭtch) [AS. crycc] 1. An assistive device prescribed to provide support during ambulation and transfers for individuals with paralysis, weakness, or injury. It also may be used to provide support for balance loss or to minimize or eliminate weight bearing on lower extremities. A variety of crutches are available. The most common is the axillary crutch, which generally is constructed of wood or aluminum. This type of crutch consists of a curved surface that fits directly under the axilla, and double uprights connected by a hand grip that converge into a single contact point at the distal end. A rubber suction tip generally is fitted to this distal end for safety. The axillary crutch should be adjusted to suit the user’s height. Other variations include the forearm crutch or Lofstrand crutch. This aluminum crutch consists of a single metal tube, a hand grip, and a metal cuff that surrounds the proximal forearm. Platform adaptations for forearm crutches, which allow individuals to bear weight through the forearm, are available.
