Is Retained Wire from Past Femur Fracture Surgery Harmful? - Orthopedics

Surgical fixation of a femoral fracture with retained metal wires?


Dear Director,
I would like to ask you a question.
Nine years ago, I underwent surgery for a closed femoral fracture.
The attending physician inserted a long metal nail into my thigh bone and wrapped several turns of wire around the fracture site.
At that time, it was mentioned that the wire would be removed, but seven years ago, the long nail was taken out.
However, the wire was encased in tissue, and the doctor advised that it did not need to be removed.
Recently, I have noticed that despite my daily habit of walking for about half an hour, I still experience mild soreness.
I would like to know if the presence of the wire in my body poses any harm and whether it would be better to remove it.
I am concerned that, due to being encased in tissue, it may be difficult to extract, and I worry that as I age, the long-term presence of the wire could lead to increasing soreness and affect my ability to walk.
Thank you for your response.

Wires in the body typically do not have any significant effects, especially if they are encapsulated by bone.
They do not need to be removed, as they will not cause future discomfort unless they protrude and irritate the skin or subcutaneous tissue, leading to inflammation and pain.
Please rest assured.

Retained wire from a past femur fracture surgery can raise concerns for many patients, especially when they experience discomfort or pain years after the initial procedure. In your case, having had a femur fracture nine years ago, with a long metal rod and wire placed during surgery, it’s understandable to be worried about the implications of the retained wire.

First, it’s important to note that retained hardware, such as wires, plates, or screws, is quite common in orthopedic surgeries. Many patients live with these materials without any issues. In your situation, the wire was left in place because it became encapsulated by soft tissue, which is a typical occurrence. When hardware is well-integrated into the body and not causing any significant symptoms, surgeons often recommend leaving it in situ, as removal can sometimes pose more risks than benefits.

However, you mentioned experiencing a mild aching sensation despite maintaining a regular walking routine. This discomfort could be attributed to several factors:
1. Soft Tissue Reaction: The body can sometimes react to foreign materials, leading to localized inflammation or discomfort. This is often a benign response but can cause intermittent pain.

2. Biomechanical Changes: After a fracture and subsequent surgery, the biomechanics of the leg can change. The presence of retained hardware may alter how forces are distributed during movement, potentially leading to discomfort in the surrounding muscles or joints.

3. Age-Related Changes: As we age, our bodies undergo various changes, including joint degeneration or muscle weakening, which can contribute to discomfort, especially in previously injured areas.

Regarding your concerns about the long-term presence of the wire and its potential to cause pain or mobility issues in the future, it’s essential to consult with your orthopedic surgeon. They can evaluate the wire's current status through imaging studies, such as X-rays or MRIs, to ensure that it hasn’t shifted or caused any complications.

If the wire is indeed encapsulated and not causing any significant issues, the surgeon may advise against removal, especially if the procedure carries risks of infection or damage to surrounding tissues. However, if the discomfort persists or worsens, discussing the possibility of removal or alternative treatments is crucial.

In summary, while retained wire from past surgeries can be a source of concern, many patients live comfortably with such hardware. Regular follow-ups with your orthopedic surgeon are essential to monitor your condition and address any emerging symptoms. If you continue to experience discomfort, they may recommend physical therapy or other interventions to help manage your symptoms and improve your quality of life. Always prioritize open communication with your healthcare provider to ensure your concerns are addressed appropriately.
