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 new techniques might be used to enhance fracture repair if healing is delayed or impaired?

- Figure 38.19 Which of the following statements about bone tissue is false? Compact bone tissue is made of cylindrical osteons that are aligned such that they travel the length of the bone. Haversian canals contain blood vessels only. Haversian canals contain blood vessels and nerve fibers. Spongy tissue is found on the inferior of the bone, and compact bone tissue is found on the exterior.arrow_forwardWhich of the following are only found in cancellous bone? canaliculi Volkmanns canals trabeculae calcium saltsarrow_forwardState the functions of the skeletal system.arrow_forward
- List four functions of the skeletal system.arrow_forwardAt his ninety-fourth birthday party, Jim was complimented on how good he looked and was asked about his health. 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. What is Jim’s probable condition?arrow_forwardanswer the following questions During what period of life does skeletal mass increase dramatically? Begin to decline? Why are fractures most common in older adults?arrow_forward
- Discuss the axial and appendicular parts of the skeletal systemarrow_forwardwhat happens to the overall structure of the skeletal system if bones are not properly calcified? Cite some examples of disorders/disease where the calcification of bones is affected.arrow_forwardPlease identify the structures of bone with the following key terms: canaliculi central canal lacuna lamella osteonarrow_forward
- 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
