Sprain vs. fractured
After a fall on the wrist, the symptoms cannot always rule out the possibility of a broken bone. In the case of a sprain, the surrounding ligaments and the joint capsule are often overstretched and strained. These injuries can cause severe pain, which can make the person concerned uncertain whether the bone is broken or not.
A fracture of the bone is often accompanied by a loud noise. However, if a ligament in the wrist tears, this too can cause a whip-like noise. An open fracture is easy to diagnose, whereas a closed, invisible fracture cannot always be clearly distinguished from a sprain.
In the case of a fracture of the wrist, an abnormal position can be an indication of an existing fracture. For example, the bones may be visibly displaced from one another. In addition, bone splinters or bone ends can also protrude clearly under the skin.
The injured wrist also feels very unstable and can usually be moved beyond the physiological range of motion. The mobility is abnormal. In the case of a sprain, on the other hand, the patient can move the affected joint less well due to the severe pain and avoids any stress.
In the case of a fracture, a rubbing sound can often be heard during movement. This can occur, for example, when bone fragments are chipped off. Both types of injury involve swelling and bleeding into the skin.
Swelling and hematomas (bruises) usually do not form until hours after the accident. Both the sprain and the fracture can both be treated in first aid using the PECH method. If a fracture is suspected, it should also be treated like a fracture until a definite diagnosis is made, because any further strain or movement can make the fracture more complicated. A reliable distinction between sprain and fracture can only be made by means of an X-ray examination. In the x-rays, cracks in the bone can be clearly seen or a fracture can be ruled out.Accordingly, it is always safer to consult a specialist after a fall and persistent complaints, who can make the correct diagnosis and then initiate the appropriate therapy.
