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?

Verified step by step guidance
1
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.
