Textbook Question
Chapter 6, Problem 5CCS
Remember Mrs. DeStephano? When we last heard about her she was being admitted for further studies. Relative to her skeletal system, the following notes have been added to her chart. Mrs. DeStephano, a 45-year-old woman badly injured in a traffic accident, is being admitted for further studies after initial treatment in the ER. Among her injuries, several relate to her skeletal system, according to her chart:
Fracture of superior right tibia (shinbone of leg); skin lacerated; area cleaned and protruding bone fragments subjected to internal (open) reduction and casted
Nutrient artery of tibia damaged
Medial meniscus (fibrocartilage disc) of right knee joint crushed; knee joint inflamed and painful
Relative to these notes:
What complications might be predicted by the fact that the nutrient artery is damaged?

He answered, “I feel good, except that some of my joints ache and are stiff, especially my knees and hips and lower back, and especially when I wake up in the morning.” A series of X-ray studies and an MRI scan taken a few weeks earlier showed that the articular cartilages of these joints were rough and flaking off and that bone spurs were present at the ends of some of Jim’s bones.

- A fireman fell from a ladder while fighting a fire and severely fractured the thigh and leg bones in his right leg. He was hospitalized for several weeks; then he was wheelchair-bound for several months while his leg bones healed. Upon removal of the cast, it was apparent that his right thigh and leg bones were thin and weak. What factors contributed to this thinning and weakening of the bones, and what should the fireman do to improve the strength of these bones?arrow_forwardJL, a 50-year-old woman, fell and broke the left tibia at the ankle. She is in the emergency department, waiting for the fracture to be immobilized. The leg hurts and she notes that the ankle is red and swollen. A diagnosis of a simple fracture and sprain (damage to ligaments) is made. What is the rationale for immobilizing the fractured bone? Include in your explanation a discussion of why movement of the affected area is painful. She is told to come back to the fracture clinic in 24 hours to have her cast checked. What could happen to the inflamed tissue if the edema increases in the casted area? What warning signs and symptoms will you look for?arrow_forwardThe appendicular skeleton consists of the bones of the (a) pectoral and pelvic girdles. (b) skull, thorax, and vertebral column. (c) arm, legs, hand, and feet. (d) limbs, pectoral girdles, and pelvic girdle.arrow_forward
