This ensures that the particular tendon being examined is actually pulling the finger. In a finger with poor venous circulation, the digit may be cyanotic and edematous. No matter where on the hand the injury has occurred, a thorough neurovascular assessment is performed. The components of the neurovascular assessment include pulses, sensibility, motion, skin temperature, color, and capillary refill. X-rays should be obtained of the affected parts.
Amputated digits are also X-rayed.
However, oblique views and stress views of a joint may be necessary. For injuries caused by excessive forces, the joint above and below the affected part are X-rayed. Radiographs not only show fracture, but they may show the presence of foreign bodies such as metal, glass, or radio-opaque debris. Wood and nonradiopaque plastic cannot be visualized by plain X-rays. Surgical scrubbing and debridement of devitalized tissue may require a trip to the operating room.
