Broken Bone Screw: Risks and Concerns After Surgery - Orthopedics

Share to:

The bone screw has broken inside the bone!


After the car accident, I fractured my left humerus and underwent surgery where a plate and screws were used for fixation.
Over a year later, the plate was removed, but the doctor mentioned that one of the screws was too tightly adhered to the bone and broke during removal, leaving a piece in the bone.
To extract it, the doctor said they would need to drill a hole around the screw.
When I asked about the potential impacts, he said there would be no effects.
I would like to know if there was any medical negligence, whether screws are prone to breaking, how common such cases are, and if it is truly without consequences.

Hello, it is not uncommon for a bone screw to break inside the bone during plate removal, and it should not be considered a medical error.
Generally speaking, retained bone screws should not have any impact on the human body.

When dealing with the aftermath of a broken bone and the surgical interventions that follow, such as the use of screws and plates for stabilization, it is essential to understand the potential risks and concerns that may arise. In your case, the situation involves a broken humerus that was surgically treated with a plate and screws, and now there is a concern regarding a broken screw that has become embedded in the bone.

Firstly, it is important to note that while surgical screws are designed to be robust and durable, they can occasionally break, particularly if there is excessive stress on the bone or if the bone has not healed adequately. The incidence of screw breakage is relatively low, but it can occur, especially in cases where the patient may have resumed activities too soon or if there are underlying issues with bone healing, such as osteoporosis or inadequate blood supply to the area.

Regarding your specific situation, the fact that a screw broke during removal is not necessarily indicative of medical negligence. Surgical procedures can be complex, and sometimes unforeseen complications arise. The surgeon's recommendation to create a hole around the broken screw to facilitate its removal is a common practice in orthopedic surgery. This approach is often necessary when a screw is tightly integrated into the bone, and it is essential to minimize damage to the surrounding tissue and bone during the extraction process.

As for the potential impacts of leaving the broken screw in place, it largely depends on its location and the patient's overall health. In many cases, if the screw is not causing pain, discomfort, or interfering with the function of the limb, it may be left in situ without significant consequences. However, there is always a risk of infection or irritation, especially if the screw is near the skin surface or if it is in a weight-bearing area.

In terms of whether this situation is common, while screw breakage can happen, it is not a frequent occurrence. Most orthopedic surgeries involving screws and plates are successful, and complications are relatively rare. However, when they do occur, they can lead to additional procedures or extended recovery times.

In conclusion, while the broken screw and the need for further intervention may be concerning, it is crucial to trust your surgeon's expertise and judgment. If you have lingering doubts about the situation or the decision-making process, seeking a second opinion from another orthopedic specialist can provide additional reassurance and clarity. It is always within your rights as a patient to ask questions and seek further information about your treatment options and the implications of any surgical decisions made.
