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 postreductionX 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.
3. There were no bone fragments in the joint space. What is normally found in this space?

- Case Scenario based upon Skeletal Joints: Leanne, age 48, jumped on her niece's hover board, only to be thrown off quickly. 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_forwardMatch the term in column A with the correct description in column B. Column A Column B 1.
