Fracture of the bone above the left ankle joint with ligament tear?


Hello, doctor! I would like to ask you about my condition.
I have a sports injury that caused a separation of the bone above the joint on the outer side of my left foot, along with a ligament tear.
After observing for six weeks, the doctor decided to perform a screw fixation surgery.
The surgery was completed on April 17th in the afternoon.
Three days later, the pain was not as severe.
However, my left foot has been moving around and I have been putting weight on it.
Will the screws that were just inserted shift or come out due to my movement or weight-bearing?

Dr. Chen Bochen reply Orthopedics


Hello, ordinary screws are not that fragile.
If a screw is loose, it usually accompanies an increase in pain, and there would be noticeable pain at the moment of injury.
If you are still concerned, you can return for a follow-up appointment and have the original surgeon take an X-ray for you.

After undergoing ankle surgery, particularly one involving the fixation of bones with screws, it is natural to have concerns about the stability of the surgical site and the potential for screw displacement. Your situation, involving an injury that resulted in both a fracture and ligament tear, necessitated surgical intervention, and it’s essential to understand what to expect during your recovery.

Firstly, it’s important to recognize that screws used in orthopedic surgery are designed to provide stability to the fractured bones and are typically made of materials that are strong and durable, such as titanium or stainless steel. Once the screws are properly placed and the surgical site is closed, they should remain in position as long as the bone heals adequately around them. However, the concern about movement or weight-bearing activities post-surgery is valid.

In the initial weeks following surgery, the bone is still in the process of healing, and the surrounding soft tissues, including ligaments and tendons, may also be recovering. During this period, it is crucial to follow your surgeon's post-operative instructions regarding weight-bearing and mobility. If you have been advised to keep weight off the affected foot or to limit movement, it is essential to adhere to these guidelines to prevent complications such as screw displacement or improper healing.

Regarding your specific concern about the screws moving due to your foot "shaking" or making contact with the ground, it is generally unlikely that normal movements will cause the screws to displace if they were correctly placed and if the bone is healing properly. However, excessive movement or premature weight-bearing can increase the risk of complications. If you feel any unusual pain, instability, or if you notice any changes in the alignment of your foot, it is crucial to contact your surgeon immediately.

In the weeks following surgery, you may experience some discomfort as the tissues heal, but significant pain or instability could indicate a problem. It’s also worth noting that some degree of swelling and stiffness is common during the recovery phase, and these symptoms should gradually improve as healing progresses.

As for your recovery timeline, most orthopedic surgeons will recommend a follow-up appointment to assess the healing process. This may include imaging studies such as X-rays to ensure that the screws remain in place and that the bones are healing correctly. Depending on the nature of your injury and the surgical technique used, your surgeon will provide guidance on when you can gradually start bearing weight on your foot and when you can resume normal activities.

In summary, while it is understandable to have concerns about screw displacement after ankle surgery, following your surgeon's post-operative care instructions is vital for a successful recovery. If you have any doubts or experience any concerning symptoms, do not hesitate to reach out to your healthcare provider for further evaluation and reassurance. Your recovery is a process, and staying informed and proactive about your health will help ensure the best possible outcome.
