Final answer:
Osteoarthritis is the most common cause of hip disability that leads to total hip replacement surgery. Fractures of the femoral neck due to osteoporosis also contribute to hip disability in the elderly. A thorough care plan post-surgery is essential for quick recovery and regaining independent ambulation.
Step-by-step explanation:
The most common cause of hip disability leading to procedures such as total hip arthroplasty is osteoarthritis. The hip is particularly susceptible to this condition, which is marked by the deterioration of the joint cartilage and underlying bone, often leading to pain and reduced mobility. Total hip replacement surgery involves replacing the damaged hip joint with a prosthesis, providing relief from symptoms and improving joint function.
In older populations, another significant cause of hip disability is a fracture of the femoral neck, commonly referred to as a "broken hip." This injury is often due to weakened bones from osteoporosis and can happen when the body's weight is placed on one limb during a step, causing the femoral neck to break. These fractures generally require surgical intervention and can result in prolonged recovery periods needing mobility assistance.
Furthermore, prolonged bed rest following such surgery can lead to severe complications such as pneumonia, bedsores, and deep vein thrombosis (DVT), the latter of which can result in a life-threatening pulmonary embolism. Therefore, a comprehensive plan of care that includes early mobilization, proper wound care, and thromboprophylaxis is crucial for patients recovering from hip replacement surgery to ensure a safe and rapid return to independence and ambulation.
