In the field of medicine, fractures are a common type of trauma, and accurate diagnosis is crucial for treatment and rehabilitation. Traditionally, doctors often use X-rays to examine fractures, but X-ray radiation poses certain risks to the human body. With the advancement of technology, medical ultrasound scanners have been widely used as a non-invasive examination method for the diagnosis and treatment monitoring of fractures. This article will introduce how to use a medical ultrasound scanner to examine fractures.

1、 Understand the basic principles of medical ultrasound scanners

Medical ultrasound scanners use the principles of sound wave propagation and echo to image human tissues. When sound waves are emitted from the scanner transmitter, they generate echoes inside the human tissue. The ultrasonic scanner receives these echoes and converts them into images. Medical ultrasound scanners can display bone structure and tissue status, such as fractures and bone density.

2、 Preparation work

Before using a medical ultrasound scanner to examine fractures, some preparatory work needs to be done:

1. Ensure that the patient is in a comfortable position and expose the injured area.

2. Clean the injured area to ensure there is no dirt or coating.

3. Prepare ultrasonic gel to improve the sound wave propagation effect.

4. Ensure that the scanner is connected and turned on.

3、 Operating Steps

The following are the basic steps for using a medical ultrasound scanner to examine fractures:

1. Apply ultrasonic gel to the injured part. Gel helps sound waves to spread better and improves image quality.

2. Turn on the scanner and select the appropriate scanning mode. Different bone structures and tissues require different scanning modes.

3. Gently place the scanning probe on the injured part coated with gel to ensure that the probe is in close contact with the skin.

During the scanning process, the doctor needs to adjust the position and angle of the probe based on the image on the display screen to obtain the best bone structure and tissue imaging.

4、 Interpreting Scan Results

After completing the scan, the doctor needs to interpret the scan results to determine if there is a fracture:

1. Observe whether there are abnormal bone structures in the image, such as fractures or displacement.

If abnormalities are found, further observe the degree, angle, and location of the fracture.

Based on the scanning results, doctors can classify and locate fractures to develop corresponding treatment plans.

5、 Precautions

When using a medical ultrasound scanner to examine fractures, the following precautions should be taken:

1. The operation process should be gentle to avoid causing additional damage to the patient's injured area.

2. It is necessary to provide sufficient explanation and comfort to the patient to ensure their cooperation with the examination.

3. If the patient has metal objects implanted in the body, such as surgical steel plates or nails, ultrasound may not penetrate and affect the examination results.

Conclusion:

Medical ultrasound scanners, as a non-invasive examination method, are of great significance for the diagnosis of fractures. By understanding the basic principles, correct operating procedures, and methods of interpreting scanning results of ultrasound scanners, we can more accurately diagnose and treat fractures, providing support and guidance for patients' rehabilitation. However, ultrasound examination also has its limitations and requires a comprehensive analysis combined with clinical symptoms and other imaging examinations. In the future, with the continuous progress of technology, we can expect medical ultrasound scanners to play a greater role in the diagnosis and treatment of fractures.
