1. What is meant by a “complete, comminuted, intertrochanteric fracture of the right hip? a. A complete fracture is when the entire bone impacted is fractured. A comminuted fracture is when the bone breaks shatters into many pieces. Intertrochanteric refers to the top part of the femur. So, a complete, comminuted intertrochanteric fracture is the upper most part of the femur is completely shattered. A comminuted fracture is common in older people, so this fracture is normal for someone Margaret’s age. (Marieb, Elaine N.R., Ph.D. “5/The Skeletal System.” Essentials of Human Anatomy & Physiology.

(Be detailed!) f. According to Wolfe’s Law, bones grow and remodel in response to the mechanical stresses that are placed upon it. When different types of stresses are placed in specific directions, the bones are remodeled and become healthy once again. For people that have osteoporotic bones or fractured bones, Wolfe’s Law must be applied during physical therapy for the bone to heal properly. The formation of the trabeculae adapts to the changes occurring as a result of weight bearing. The external cortical – one of the two types of osseous tissues that form bones - portion of the bone then undergoes changes as well. (Wikipedia. “Wolfe’s Law.” www.wikipedia.com. Wikimedia Foundation Inc.,, 7 Dec. 2012. Web.) 7. In addition to the physical therapy benefits, why else might Margaret’s physician want her to avoid prolonged bed-ridden activity? (Think of Wolfe’s Law) g. If Margaret remains on bed rest for too long, there are many negative affects that will surface as a result of this. Muscle strength will decrease daily. The lack of gravitational forces may lead to osteopenia – when bone mineral is lower than normal. Joints begin to show a loss of connective tissue after too much inactivity. Immobilization also causes ligament strength to decrease tremendously. Cardiovascular efficiency decreases, along with blood and plasma volumes. When there is less daily activity, the amount of stress the skeleton has to endure is less, which causes a loss in bone
