Radiology is a special branch of medical science that uses various techniques of imaging for the diagnosis and the treatment of several types of diseases in the body. The different types of imaging techniques used in radiology are X-rays, Computerised Tomographic scan (CT Scan), ultrasound, Magnetic Resonance Imaging (MRI) and nuclear medicine which includes Positron Emission Tomography(PET).

Role played in evaluating hip replacement
Hip replacement surgeries have become extremely common in the recent times, and radiological evaluation remains the mainstay of the overall hip replacement procedure. Thus, the role played by radiology is quite significant in such situations. All the specific anatomical landmarks and the measurements are used to make sure the placement is perfect during the hip replacement surgery. Radiological imaging helps in the assessment of the following conditions that are as discussed below.

The length of leg
The inequality in the length of the two legs is prevalent after a hip replacement surgery which can create a great deal of discomfort and inconvenience to the patients. A greater difference in the length of the two legs increases the chances of dislocation, and this is a situation where radiological evaluation plays a crucial role. With the help of radiological imaging, the length of the legs can be made almost equal.

The horizontal center of rotation
In this case, horizontal center of rotation helps in the assessment of the acetabular component of the prosthesis. This is calculated by the measurement of the distance between the center of the head of the femur and the acetabular teardrop. This distance should be bilaterally equal, and it is just not possible without the help of the imaging techniques of radiology.

Acetabular inclination
The acetabular inclination is the angle formed between the face of the cup and the transverse axis. If the angle is less, then it results in a stable hip, but the abduction is limited. On the other hand, if the angle increases then there are high chances of dislocation of the hip. Thus, with the help of radiological evaluation, proper and effective angular inclination is given which is optimum for the patient.

The stem positioning of the femur
The main aim of the stem positioning of the femur in a hip replacement surgery is placing the stem in a position which is neutral within the shaft. To get a proper idea of the positioning, the imaging techniques are of utmost importance which cannot be achieved perfectly without the imaging.

Thus, the crucial role the different techniques of radiological imaging plays during the overall procedure of a hip replacement surgery can be perceived. With the use of the different imaging techniques, the results obtained are closer to perfection.

How Radiological Evaluation Can Help In Case Of Hip Replacement?

Knee pain is something that can affect anyone - irrespective of their age. While sometimes it may be of minor importance - and can easily be handled by self-care, often, lingering pain is a manifestation of some other serious underlying problem, such as arthritis. In this case, it is imperative that you consult a doctor and take appropriate measures to combat it.

Causes :

Arthritis: The chief cause of lingering knee pain, arthritis itself can be of a number of types:
 Osteoarthritis, which is a result of deterioration of cartilages due to wear and tear
 Rheumatoid Arthritis, an inflammatory chronic disorder
 Septic Arthritis, causing pain, swelling and redness.
 Gout caused due to the development of uric acid crystals in the joints
Fractures: These are caused by the breaking up of the kneecap due to falls or collisions.
ACL Injuries: Caused due to the tearing of the anterior cruciate ligament (that connects the femur and the shinbone). Especially common in sportspersons such as footballers or basketball players.
Meniscus tears: The meniscus or the rubber-like cartilage (that acts as a shock absorber) can be torn by sudden jerks or excess pressure.

Symptoms:The major symptoms of knee pain include weakness, redness, instability, stiffness or the inability to properly straighten or move the leg. Often, a deformity is also visible, such as a bone sticking out of the leg - in which case it is advisable to consult a doctor immediately.

Possible risks :Factors which include the odds of being inflicted by knee pain and cause serious complications include :
Being overweight: This exponentially increases the stress or pressure that is applied on the knee joints - even in doing mundane tasks like walking up and down stairs.
Excessive physical activity: Some activities, such as sports apply excess stress on the knees as compared to other tasks.
Loss of muscle flexibility: Tightness or weakness in muscles causes increasing number of problems in the knees.

All About Knee Pain

Your knee is a very complex structure consisting of bones, ligaments, cartilage, tendons, muscles and meniscus. Most people encounter knee pain at some point in their lives. If your knee pain is chronic in nature, then it may last for a prolonged period.

Many causes may be responsible for your knee pain. Some of the causes are stated as follows:
1. Your knee is very much prone to injuries. Knee injuries may happen due to accidents, falling down carelessly or while playing sports. The most common knee injuries that may be the cause for your knee pain are mentioned as follows: 
a) Fractures may cause you to feel pain in the areas of your knee bones.
b) Anterior Cruciate Ligament injury (ligament injury caused by twisting and a sudden motion) or Medial Collateral Ligament injury (injury to the tissue in the insides of your knee) is very common to sportspersons and may be the reason for severe knee pain.
c) Sometimes your knee bones may get dislocated from their usual alignment. This can also make you experience severe knee pain.
d) Ligament injuries, meniscus tear or tendon tear can also be responsible for your knee pain.

2. Sometimes pain in your buttock or foot region can also result in mild knee pain.

3. At times chronic problems like osteoarthritis that affects the cartilage can cause the problem of knee pain. Other chronic problems like Gout, rheumatoid arthritis can also cause severe knee pain.

4. Being overweight can also result in knee pain.
The symptoms of knee pain may be different in each case. The most common symptoms are mentioned below:
a) Stiffness of knee
b) Swelling of your knee
c) You may also feel unstable
d) Difficulty in walking or bending of your knee.
e) You may notice redness in your knee area.

Knee pain must not be ignored. It is highly recommended for you to seek advice from an orthopedic as soon as you encounter any of the above mentioned symptoms.

Heel Pain - Effective Ways To Put It At Rest!

Mobility for a person is very important, and when you look through, the hip is a very important component to this. It connects the upper and lower parts of the body and helps in movement. It is a ball and socket joint, where the hip bone provides a socket, into which the upper part of the thighbone (femur) sits into, allowing for free movement.

Like any other human organ, the hip also is prone to damage. Be it natural ageing, infection, injury, or diseases, hip movement can be affected, leading to limited movement and increased pain and stiffness. For these people, being able to get back a hip which will allow them to be back on their feet is a boon for sure. It helps in relieving pain and improving mobility, almost giving people a second lease of life.

Reasons for hip replacement:

With natural ageing, the hip joint can lose its ability to move, due to normal wear and tear of the hip and thigh bones
Diseases of the hips (infectious or autoimmune) can also lead to hip replacement
Injury or trauma is another major cause that requires hip replacement
Joint problems, leading to repeated dislocations
Tumours of the relevant bones
Understanding the procedure in detail

The affected bones (whether diseases or worn out) are replaced with a prosthesis which is compatible with the normal body tissue.
While some materials fuse to the natural bone, others do not and are simply placed as a separate unit
This is a surgery which requires hospitalisation and stays for up to 5 days depending on patient s overall health condition
The entire procedure may take a couple of hours and is usually done under general anaesthesia
An incision is made through the side of the hip
Both the hip and the thigh joints are prepared, diseased tissue removed, re-shaped, etc. to make way for the prosthesis
The prosthesis is introduced through the same incision and positioned into place
As noted earlier, there are two types. The ones which fuse to the bone have pores in them into which normal bone eventually grows.
The other variety is the cemented version, and a glue is used to keep it in place
Most doctors now use a combination, that is cement a porous prosthesis, into which bone will grow, and the incisions are closed
The patient stays in the hospital for 1 to 4 days depending on overall health
Once discharged, infection and pain control are continued
Exercise and physiotherapy play a major role in restoring normal function
Weight management is also very important

Hip Replacement - Understanding The Procedure In Detail!

Human bones are continuously being removed and formed, which is necessary for its proper maintenance. However, in certain cases, especially with aging, some bones and joints will be worn down to an extent where the body will not be able to reform them. This is especially true in the case of hips, which may become worn due to age or other problems within the body. 

Hip replacement surgery 
When this happens, a hip replacement surgery can be performed to replace the original joints with a prosthesis or artificial hip, which is usually made out of metal or a specially formed composite material or even a combination of the two. Along with other parts, it replaces the natural hip with an artificial hip to restore mobility and other related functions.

Benefits of hip replacement surgery:
1. Lessening hip pain: This is one of the major factors as well as symptoms of requiring hip replacement surgery. Due to the grinding down of the bones, even the slightest movement causes pain and after the surgery and the recovery period, the pain is lessened.

2. Correction of bone deformity: When the bones grind down and are abnormally reformed, deformities may occur reducing mobility. Artificial hips will ensure that deformities are corrected and resulting problems are thus eliminated.

3. Return to normal activities: This is possibly one of the primary advantages of this surgery, although it entails a long recovery period. However, most patients can get back to their normal activities and are able to resume a pain free life.

4. Ability to have painless sleep: Many people who suffer from hip displacements or bone deformities are not able to sleep properly due to pain. After the surgery and the recovery period, they can return to normal functions and habits, thus are able to sleep properly.

5.  Leg strength increase: Many patients tend to have an increase in their leg strength as one side of the hip tends to become very weak due to bone problems before surgery. After surgery and recovery, the same side tends to have an increased strength due to the implant.

6. In most cases a lifelong solution to hip problems: As the hip replacement prosthesis is made out of metal and if the operation is successful, it usually tends to last till the end of a person's life and this area usually doesn't tend to have problems again.
