"while backcountry skiing with friends in deep, fresh powder, lena caught her right ski on a hidden branch and fell hard. she suffered multiple injuries to her skeletal system, particularly to her right lower limb, because of the forces applied to the limb when her ski suddenly stopped, and her right upper limb, because she put her right arm out in front of her to brace against the fall. questions: 1. lena is told she has broken her wrist, fracturing the scaphoid and one of the bones of her forearm. which bone is it that she has fractured? why? the head of the radius articulates with which of the following bones? a. the lunate because it is next to the scaphoid. b. the pisiform because it is a commonly broken bone of the wrist. c. the distal end of the radius because it articulates with the scaphoid. d. the distal end of the ulna because the ulna is a major bone of the wrist.2. lena has a spiral fracture of her tibia just above where her ski boot ends. what is a spiral fracture, and why might this be a common injury to the tibia in skiing? a. the ski boot breaking apart during a fall cuts the leg, slicing through the tibia. b. rotation forces applied to the lower limb during a fall twist the leg just above the ski boot, fracturing the tibia. c. ski boots do not properly support the ankle, resulting in a separation of the tibia from the calcaneus. d. the tibia is the weakest bone of the lower leg and shatters when the leg takes a blow from the side."
