What is a common complication associated with a hip fracture in the elderly?

A common complication associated with a hip fracture in the elderly is avascular necrosis of the femoral head. This condition occurs when there is a loss of blood supply to the femoral head, which can happen after a fracture due to disrupted blood vessels. In older adults, the risk of avascular necrosis increases not only due to age-related factors but also due to potential complications from the fracture itself, such as displacement or improper healing. If the blood supply is compromised, the bone tissue can begin to die, leading to severe pain and joint dysfunction.

This outcome is particularly concerning as avascular necrosis can lead to long-term issues with mobility and may necessitate surgical intervention, such as joint replacement in more advanced cases. It’s important in elderly patients to monitor for signs of avascular necrosis following a hip fracture to address any complications proactively.
