Persistent Ankle Pain After Surgery: Unremoved Screw and Complications - Orthopedics

Share to:

After an ankle fracture, a fixed steel pin was not removed, and the sutures are said to be rejected by the foot. It has been painful to walk for several months?


Hello Doctor, earlier this year I had surgery to remove three fixation screws from an ankle fracture that occurred a year ago.
One of the screws broke and could not be removed, and it is currently lodged in the bone.
Since then, my foot has started to hurt.
The doctor mentioned that the sutures and my foot's tissue are rejecting each other, which is a rare situation.
I have been taking medication for two to three months, but my foot still hurts when I walk, and it even affects my knee, causing soreness.
Could you please explain what might be happening in this situation and what I should do? Is there inflammation? This is truly distressing.

If an ankle fracture has healed, it should not be related to the presence of screws or sutures.
Consideration should be given to the condition of the ligaments after the injury or the possibility of post-traumatic arthritis.
Please consult your attending physician for further details.

Persistent ankle pain after surgery, especially following the removal of screws from a previous fracture, can be quite concerning and frustrating. In your case, it seems that one of the screws could not be removed due to it being fractured and lodged within the bone. This situation can lead to several complications, including persistent pain, inflammation, and even the potential for further injury or complications in adjacent joints, such as the knee.

Firstly, it is important to understand that the presence of a retained screw can sometimes lead to chronic irritation or inflammation in the surrounding tissues. The body may react to the foreign object, which can cause pain and discomfort. This is particularly true if the screw is in a location where it can irritate surrounding soft tissues or if it is causing mechanical issues during movement. The pain you are experiencing in your ankle could be a result of this irritation, and it may also contribute to compensatory movements that can lead to pain in other areas, such as your knee.

The symptoms you describe, including pain during walking and the sensation of discomfort radiating to your knee, may indicate that the ankle is not functioning properly due to the retained screw. This can lead to altered biomechanics, which can place additional stress on the knee joint, resulting in pain and discomfort there as well. It is also possible that the pain is exacerbated by inflammation in the ankle joint itself, which can occur due to the irritation caused by the screw or from other factors such as overuse or compensatory movements.

Given that you have been experiencing these symptoms for an extended period, it is crucial to consult with your orthopedic surgeon or a specialist in musculoskeletal disorders. They may recommend imaging studies, such as X-rays or an MRI, to assess the position of the retained screw and to evaluate the surrounding soft tissues for any signs of inflammation or damage. This will help determine whether the screw is indeed the source of your pain or if there are other underlying issues that need to be addressed.

In terms of management, treatment options may include physical therapy to strengthen the muscles around the ankle and knee, improve range of motion, and address any compensatory movement patterns. Pain management strategies, such as anti-inflammatory medications or corticosteroid injections, may also be considered to reduce inflammation and alleviate pain. If conservative measures do not provide relief, surgical options to remove the retained screw or address any other issues may be necessary.

In conclusion, persistent ankle pain after surgery, especially with a retained screw, can lead to significant discomfort and impact your quality of life. It is essential to seek further evaluation from a healthcare professional to determine the underlying cause of your symptoms and to develop an appropriate treatment plan. Early intervention can help prevent further complications and improve your overall function and well-being.

Hello, generally after this surgery, you should avoid putting weight on the foot for 4-6 weeks. However, occasionally putting weight on it once or twice should not cause it to loosen, but it is best to avoid doing so as much as possible.
