You arrive on the scene where a person without a pulse was found. Someone on the scene performed CPR, but the individual unfortunately could not be revived. On postmortem examination, it is discovered that several ribs and the xiphoid process were fractured. What likely caused these fractures?
Ch. 7 The Skeletal System
Chapter 7, Problem 9.5a
Ms. Hendrix suffered a severe hip fracture that required hip replacement surgery. After an extended recovery period, she is undergoing physical therapy to regain strength and mobility.
a. Which bone is involved in a hip fracture, and what part of the bone is likely to be fractured?

Identify the bone involved in a hip fracture, which is the femur.
Determine the specific part of the femur that is most commonly fractured in a hip fracture, which is the femoral neck.
Understand that the femoral neck is the region just below the ball of the hip joint, making it a common site for fractures, especially in older adults.
Recognize that the femoral neck connects the head of the femur to the shaft, and its fracture can significantly impact mobility.
Consider the implications of a femoral neck fracture, such as the need for hip replacement surgery and subsequent physical therapy for recovery.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Hip Anatomy
The hip joint is formed by the femur (thigh bone) and the acetabulum of the pelvis. A hip fracture typically involves the femoral neck, which is the area just below the ball of the hip joint. Understanding the anatomy of the hip is crucial for identifying the specific location of fractures and the implications for treatment.

Types of Hip Fractures
Hip fractures can be classified into different types, including intracapsular and extracapsular fractures. Intracapsular fractures occur within the hip joint capsule, often affecting blood supply to the femoral head, while extracapsular fractures occur outside the capsule. Recognizing these types helps in determining the appropriate surgical and rehabilitation approaches.

Rehabilitation Post-Surgery
Post-surgical rehabilitation is essential for recovery after a hip replacement. It typically involves physical therapy focused on restoring strength, flexibility, and mobility. Understanding the rehabilitation process is vital for patients to regain independence and improve their quality of life following a hip fracture and surgery.

Textbook Question
Some health practitioners claim that the cranial bones are moveable and that they are able to move these bones to treat a variety of conditions. Is this likely to be true in an adult? Why or why not?
