Document Summary
Plain film/x-ray initial study used in most evaluations of bone. Minimum of two films at right angles to each other (usually ap and lateral) to rule out a fracture image proximal and distal joints (particularly important where there are paired bones e. g. radius/ulna) Not very effective in evaluating soft tissue injury fast, inexpensive, readily available. Evaluation of bone cortex and type of cortical expansion for comminuted fractures and complex structures (skull, spine, acetabulum, calcaneus, sacrum) Iv contrast may be used to determine lesion vascularity. Excellent for visualization of bone marrow and surrounding soft tissues (ligaments, tendons, joint capsules, menisci, cartilage) can visualize vascular structures without need for contrast. Diagnose tendon and ligament injury (e. g. rotator cuff injury) Determine if lesions are cystic or solid. Approach to fractures: look for fracture lines (abnormal black lines, look for discontinuation/disruption of cortex border, look for joint space narrowing/widening, look for soft tissue involvement (swelling, calcification)
