General Orthopaedic Problems

Common Orthopaedic Problems


Self-Diagnose can bring more harm than treating it. It is good to know more about the injury but definitely not to the point of self-treatment. It will be much safer to get treated by Our Doctor, for more information or to book an appointment with Singapore Sports and Orthopaedic Clinic, you can call (+65) 6471 2635, the hotline is open 24 hours. You may also send us an enquiries about general orthopaedic problems or for an appointment or question about general orthopaedic problems

Ultrasound Scan

What is Ultrasound Scan?

Ultrasound scans are images of the internal organs created from sound waves. The images are produced when the sound waves are directed into the body then reflected back to a scanner that measures them.


How does an Ultrasound work?

The ultrasound scanner looks like a small paint roller. As it moves back and forth over the body, it sends sound waves through the skin and muscles. These waves are then turned into an image that appears on a TV screen.


What does Ultrasound used for?

• Help to monitor the growth of an unborn child, and check for abnormalities.
• Detect abnormalities of heart structures such as the heart valves.
• Help to diagnose problems of the liver, gallbladder, pancreas, thyroid gland, lymph nodes, kidneys, bladder
• Detect abnormal widening of blood vessels

Computerised Tomography (CT) Scan

What is a Computerised Tomography (CT) Scan?

A Computerised Tomography (CT) scanner is a special kind of X-ray machine. Instead of sending out a single X-Ray through your body as with ordinary X-Ray, several beams are sent simultaneously from different angles. Thus the result of Computerised Tomography (CT) scan is much more detailed compare to X-Ray.

How does a Computerised Tomography (CT) scanner work?

The X-Ray from the beams are detected after they have passed through the body and their strength is measured.
Beams that have passed through less dense tissue such as the lungs will be stronger, whereas beams that have passed through denser tissue such as bone will be weaker.
A computer can use this information to work out the relative density of the tissues examined.

How is a Computerised Tomography (CT) scan carried out?

During the scan the patient lies on a bed, with the body part under examination placed in the opening of the scanner. The bed then moves slowly backwards and forwards to allow the scanner to take pictures of the body. The length of the test depends on the number of pictures and the different angles taken.

Magnetic Resonance Imaging (MRI)

What is Magnetic Resonance Imaging (MRI)?

Magnetic resonance imaging (MRI) is a non-invasive medical test that helps physicians diagnose and treat medical conditions.
MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. The images can then be examined on a computer monitor.

How safe is Magnetic Resonance Imaging (MRI)?

MRI is quite safe in the majority of patients. Certain patients are unable to do an MRI such as people that are nervous in small spaces (claustrophobic) and those with implanted medical devices such as aneurysm clips in the brain, heart pacemakers and cochlear (inner ear) implants. Also, people with pieces of metal close to or in an important organ (such as the eye) may not be scanned. There are a few additional safety considerations and some exceptions based on individual circumstances. As MRI is using powerful magnetic field it may disrupt the scan images or even damage the items that is magnetic.

What are the uses and advantages of a Magnetic Resonance Imaging (MRI) scan?

Magnetic Resonance Imaging (MRI) scanners are good at looking at the non-bony parts or soft tissues of the body. In particular, the brain, spinal cord and nerves are seen much more clearly with MRI than with regular x-rays and CAT scans. Also, muscles, ligaments and tendons are seen quite well so that MRI scans are commonly used to look at knees and shoulders following injuries. A MRI scanner uses no X-Ray or other radiation. A disadvantage of MRI is it’s higher cost compared to a regular X-Ray or CAT scan.

X-Ray

What is X-Ray?

An X-ray picture is a picture of the shadows cast by the denser materials (like bones) in your body.

If the doctor suspects that you have a broken bone he will probably take an X-ray picture to check. X-rays are made of the same electromagnetic particles as light but with a much shorter wavelength. These shorter wavelengths allow X-rays to pass through the human body.

X-rays are produced in a special tube. Most of the air is pumped out of the tube. The tube holds a negatively charged electrode called a cathode. Inside the cathode is a tungsten wire which will give off electrons when heated. The tube also contains an anode, or target electrode. The anode is also made of tungsten. When the electrons emitted by the cathode hit the tungsten anode they are stopped abruptly and some of their energy is turned into X-radiation.


How is X-Ray Done?

The patient is placed between an image receptor and an X-ray emitter. Originally the image receptor was a photographic plate, but there are a variety of technologies in use today. Denser parts of the body, such as bone, block more X-rays. As a result of the degree to which bone partially blocks X-rays, a corresponding negative image appears on the image receptor. A regular photograph is the product of how much and of what kind of visible light makes contact with a photographic plate; X-rays work the same way, except that they can pass through the solid matter found in the body.


Preparing for X-Ray

You would need to undress whatever part of your body needs examination. You may wear a gown to cover yourself during the exam, depending on which area is being X-rayed. You may also be asked to remove jewelry, eyeglasses and any metal objects that may obscure the X-ray image, because these objects can show up on an X-ray. Before some types of X-rays you’re given a liquid called contrast medium. Contrast mediums, such as barium and iodine, help outline a specific area of your body on the X-ray image.
