45-Year-Old Female with Dislocated Hip
In the previous chapter, you met Kayla Tanner, a 45-year-old mother of four who suffered a dislocated right hip in a car accident. Prior to the closed reduction, the doctors noted that her right thigh was flexed at the hip, adducted, and medially rotated. A widened joint space in the postreduction X ray showed that the reduction was not complete, but no bone fragments were visible in the joint space. Mrs. Tanner was scheduled for immediate surgery.
The surgeons discovered that the acetabular labrum had detached from the rim of the acetabulum and was lying deep within the joint space. The detached portion of the labrum was excised, and the hip was surgically reduced. During the early healing phase (first two weeks), Mrs. Tanner was kept in traction with the thigh abducted.
6. Hip dislocations are classified as anterior or posterior depending on which direction the head of the femur is facing after it dislocates. Based on the description from question 5, which type of dislocation did Mrs. Tanner suffer?

This term is related to the term “metatarsals.” What are metatarsals, where are they located, and how do you think they are related to metatarsalgia? High heels can cause stress fractures, which are small cracks in the bone that usually appear after repeated mechanical stress, instead of after a significant acute injury. What other condition described in this chapter involves a similar process? What are bunions and osteoarthritis of the knee? Why do you think they can be caused by wearing high heels?arrow_forward

As a result, she separated her right shoulder at an articulating point. An articulation is where two bones come together, otherwise, called a joint. A joint can be defined as the location where two bones come together allowing movement. What is the most commonly separated joint in the shoulder - name the joint and the two bones that articulate? What surrounding tissues might also be damaged? How will the inflammation affect Leanne? What is the difference between a separation and a dislocation? If Leanne had suffered a dislocation, what joint would this be and the bones involved?arrow_forwardcase scenario based upon the skeletal system: Michael, age 12, had a horrible ATV accident on his grandpa's farm.the four wheels flipped over on top of his leg,creating a compound fracture of his left femur.the fracture was located at the site of his growth plate.what is a compound fracture and what is the growth plate?is there a possibility that Michael will not walk properly ever again? if so why ? please explain the complications that may arise from a compound fracture and from the disruption of his growth plate.arrow_forward
