How to diagnose thumb fracture Three methods to diagnose thumb fracture

Directory method 1: check the signs of thumb fracture 1, and check whether there is any sharp pain at the lower end of thumb. 2. See if the injured part is deformed. 3. See if your thumb can move. 4. Pay attention to whether the thumb feels numb or cold. 5. Check whether there is swelling around the thumb. 6, pay attention to your thumb may have different types of fractures. Method 2: Recognize the symptoms of sprain 1 and make sure that it is a sprained thumb rather than a fracture. 2. Check whether you can move your thumb backwards. 3. See if there is slight swelling. 4. Pay attention to where the pain comes from. Method 3: Find a doctor to evaluate and diagnose your thumb injury 1, see a doctor or go to the emergency room. Take an X-ray of your thumb. Discuss with your doctor to see if you can scan CT. If you have an accident or are seriously injured and think that your thumb may be broken, then you must know whether your thumb is broken or sprained, and what are the important signs. From the first step below, carefully check whether it is a fracture or a sprain, and know what to do in the medical room.

Methods 1: Check the signs of thumb fracture.

1, check whether there is any tingling at the lower end of thumb. When your thumb hurts, you will naturally feel severe pain. The reason why it hurts is because there are nerves around the bone-the bone is broken, and the broken bone will stimulate or oppress the surrounding nerves, causing pain. If you don't feel severe pain after the injury, there is probably no fracture. If you touch your thumb, it should hurt. No matter where you hurt your thumb, the place where you feel the pain most easily is the lower end.

2. See if the injured part is deformed. You should see if your thumb is normal-if it is bent at a strange angle or awkwardly twisted or something. You should also check whether there are any bones sticking out of the skin. If you find any of the above, it must be a fracture. Your thumb is likely to be bruised, which is the result of the rupture of internal capillaries.

3. See if your thumb can move. If your thumb is broken, it will hurt to move it. The ligament connecting the bones is likely to fail completely, making your thumb unable to move. It is especially important to check whether you can move your thumb backwards. If you can move backwards without pain, it's probably a sprain rather than a fracture.

4. Pay attention to whether the thumb feels numb or cold. The compressed nerve will not only cause pain, but also numb your thumb and may feel cold at the same time. This is all because the blood vessels leading to the thumb and surrounding tissues are blocked by the fractured or swollen fluid. If the blood supply to the thumb is insufficient, it may turn green.

5. Check whether there is swelling around the thumb. When you hurt a bone, it will swell around. This is because the fracture will lead to subcutaneous bleeding, which will lead to swelling around. Generally, the thumb will swell up after 5- 10 minutes of injury, and then it will become very hard. Thumb swelling also affects the finger closest to the thumb.

6, pay attention to your thumb may have different types of fractures. Most fractures (or fractures) occur at the root of the thumb, and such injuries are all at the fracture site, which are mainly divided into two types, namely intra-articular injuries and extra-articular injuries. Intra-articular injury: This kind of fracture usually requires surgical intervention because it will affect the normal function of the hand. This kind of fracture includes Bennett fracture (fracture or dislocation of the first metacarpal base) and rolando fracture (fracture of the metacarpal base into three segments).

Extra-articular injury: this kind of fracture generally does not require surgery, and then includes dislocation of the thumb.

Method 2: Understand the symptoms of sprain.

1. Make sure you sprained your thumb instead of breaking it. If you don't have a broken bone, then you may have sprained it. A sprain is a tear of ligament (fibrous connective tissue connecting bones). Although it doesn't hurt as much as a fracture, it hurts to sprain your thumb. Whether it hurts or not depends on your tolerance for pain.

2. Check whether you can move your thumb backwards. If your thumb is sprained instead of broken, you can still move backwards (although you may not be able to move in other directions). This is because a sprain only hurts the ligament but not the bone, which means that even if the ligament is injured, the bone is still connected, so it can still move backwards.

3. See if there is slight swelling. A sprain can cause mild to moderate swelling, but it is not as serious as a fracture. The bone will not bleed after sprain (the blood from broken bone is the main cause of swelling). However, the blood vessels in the surrounding tissue may rupture, and then cause some swelling.

4. Pay attention to where the pain comes from. When you sprain your thumb, the pain will come from the ulnar ligament of your thumb (just between your thumb and your hand). This kind of sprain often happens to some skiers, who are injured because of improper grip on the ski pole.

Method 3: Let the doctor evaluate and diagnose your thumb injury.

1, doctor or emergency room. If you think your thumb may be broken, you should go to the emergency room and repair it immediately. If you wait too long, the congestion and swelling caused by the fracture will make the bone very difficult to return, which may make your thumb never go back.

Take an X-ray of your thumb. When you go to the hospital, you will probably be asked to take an X-ray. X-ray can check the fracture of thumb, and finally give you a diagnosis of whether it is really a fracture. Not all fractures can be reflected in one X-ray, so the doctor may ask you to make more postures and take more photos so as to make a correct diagnosis. A sideways shot has three directions: sideways is to let the X-ray hit the side of the hand, and then the thumb is up.

Oblique position: Oblique position means that the hand is inclined, the light comes from the side and the thumb is up.

Front and back position: the front and back position is to put your hand flat and then polish it from above.

Discuss with your doctor to see if you can scan CT. Sometimes CT scanning is also called CAT scanning. CT scanning uses X-ray scanning and computer to reconstruct the structure in your body (here, your thumb). In this way, your doctor can know more about your injury and give you a more suitable treatment plan. If you are pregnant, you must tell your doctor, because CT scan may hurt the baby.

Tips Whether it is a sprain or a fracture, it is best to go to the hospital to take good care of your thumb.

Warning If you are pregnant, tell the doctor before taking X-rays. Babies are very sensitive to X-rays, so if you are pregnant, you'd better not use this method to diagnose whether your thumb is injured.
