Can a strong impact cause a fracture?


Doctor, I bumped my forearm the day before yesterday, and it's very painful.
It hurts when I press on it, but there's no bruising.
Could there be a fracture? Can I apply a medicated patch? Is it okay to use Yao Guo (a type of topical ointment)?

Dr. Shi Guozheng reply Orthopedics


A contusion or impact injury can be very painful, and if the pain is severe enough to prevent movement or lifting the affected area, it may indicate a fracture.
If movement is still possible without significant pain, a fracture is less likely.
Generally, rest and medication can help improve the condition, and topical treatments are not recommended.

When you experience a hard hit to your forearm, it is natural to be concerned about the possibility of a fracture, especially if you are experiencing significant pain. While bruising is a common indicator of injury, the absence of visible bruising does not rule out the possibility of a fracture. Fractures can occur without external signs, particularly in cases of stress fractures or hairline fractures, which may not be immediately visible on the surface.

In your case, the intense pain you are feeling when pressing on the area could suggest that there is some underlying injury, which could range from a simple contusion (bruise) to a more serious fracture. It is important to note that the forearm consists of two bones: the radius and the ulna. A fracture in either of these bones can lead to significant pain and functional impairment.

To determine whether you have a fracture, it is advisable to seek medical attention. A healthcare provider will likely perform a physical examination and may recommend imaging studies, such as an X-ray, to assess the condition of the bones in your forearm. If a fracture is confirmed, the treatment will depend on the type and severity of the fracture. Some fractures may require immobilization with a splint or cast, while others may necessitate surgical intervention.

In the meantime, there are several self-care measures you can take to manage your pain and reduce swelling. Applying ice to the affected area can help alleviate pain and minimize swelling. Make sure to wrap the ice pack in a cloth to avoid direct contact with the skin, which can cause frostbite. Additionally, elevating your arm can help reduce swelling.

Regarding the use of topical treatments, such as medicated patches or ointments, these can provide temporary relief for muscle pain or superficial injuries, but they may not be effective for deeper injuries like fractures. If you choose to use a topical treatment, ensure that it is appropriate for your symptoms and follow the instructions on the packaging.

It is crucial to avoid putting weight or pressure on the injured arm until you have a clear diagnosis. Continuing to use the arm without knowing the extent of the injury could exacerbate the problem and lead to complications.

In summary, while a hard hit to the forearm can potentially cause a fracture, the only way to confirm this is through medical evaluation. Given your symptoms, it is recommended that you see a healthcare professional as soon as possible for an accurate diagnosis and appropriate treatment. Early intervention can help prevent further complications and promote a better recovery.
