Document Summary
Cancellous, lamellae only on lines of maximum stress. Metaphysis (lared area before end of bone) Short bones are cancellous covered in compact (carpals and tarsals) Destrucion of aricular carilage and subchondral bone with scarring. Age: loss of coordinaion, osteo, younger people take more risks. Health hx: ca, vitamin d, osteo, long term steroid use. Open: higher risk of infecion, can be traumaic or secondary to disease (cancer or osteo) Bleeding: creates hematoma at fracture which turns into clot in 72 hours. Deformity: abnormal posiion allows muscle to pull fragments. Edema: penetraion of bone through skin/sot issue, bleeding into surrounding skin. Ecchymosis: discoloraion from extravasaion of blood in subcutaneous issue, may appear immediately. Neurovascular assessment: color, temp, cap reill, peripheral pulses, edema, sensaion, motor funcion, pain. 5 p"s: pain, pulse (distal to injury), pallor, paresthesia (feeling), paralysis (movement) Pain scale, neurovascular status (with 5 p"s), ice, elevate. Splints, casts, external ixaion and tracion to immobilize joint.
