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?

One part of the human body is essential for the efficient functioning of another. The hip joint provides support to your overall body weight while you are at ease or in motion. Suffering from medical problems pertaining to the hip can impede free movement; walking, running, stooping, sitting or even lying down will cause immense pain and discomfort in such a situation. While certain bodily disabilities come with old age and are in most cases unavoidable; some others can actually be controlled through physical exercise.

Take a look at a few stretches to improve your hip mobility:-

Stretch like a pigeon- this yoga loosens up muscle tension in and around a person's hip. Your right leg must be stretched behind while the upper part of your body bends over a folded left leg in front. Your head rests on your coupled hands. This stretch improves the shape of your hip as well.
Try to be an eagle for hip firmness- to align your body in the perfect eagle pose; you probably need to be a conjurer; that is the kind of flexibility the posture requires. Be a half chair making your hands intersect above your head while your left leg crosses the right one. The pressure is on your hip making it strong. Your body has to be in one single line.
Sit in the chair pose- crouching on your haunches with your torso inclined to the front is a good way to better hip mobility. This exercise also relieves you of back pain. It adds potency to the muscles of your upper thighs thus giving a well- rounded hip extra support.
Stoop in the downward doggy pose- the downward doggy pose helps you concentrate on the fullness of your hips. The back muscles are stretched and the problem of a small, rickety hip is dealt with through this yoga. Your legs should be erect at the knees and should be stretched apart depending upon the width of your hip. The rest of your body should bend in a forward arch while your spread hands touch the ground.
Try out the benefits of world's greatest stretch- world's greatest stretch involves a series of stretches that not only accentuates your hipline making your hip muscles adaptable to stress but also tones muscles in other parts of your body. It is a three- fold exercise. The second step is the most difficult where your body is balanced on a half folded right leg and you're required to touch the ground with your right elbow.

Tips to Improve Hip Mobility

Damaged hips can cause great distress in carrying out daily activities, such as walking, getting dressed and many more. If you have damaged one or both of your hips, and it causes you great pain, you may require a hip replacement. It is a common form of surgery in which a damaged hip joint gets replaced with an artificial one. This is known as prosthesis.

Conditions which lead to hip replacement

Osteoporosis where the cartilage inside a hip joint gets worn out, and the bones rub with each other as a result
Rheumatoid arthritis, which is caused when the immune system attacks the hip joint lining by mistake
If the hip joint gets damaged severely during an accident or fall
The purpose of a replaced hip joint is to provide pain relief, improve the hip s function, improve your ability to carry out day-to-day activities and improve your overall quality of life.

Procedure
A hip replacement is usually carried out under general anesthesia. An incision is made in the hip by the surgeon and the damaged hip joint is removed through it. It is replaced with an artificial metal alloy or a ceramic joint. The surgery takes approximately 60 to 90 minutes for completion.

Recovery
After the surgery, a walking aid such as crutches is required for up to four to six weeks. You may enroll for an exercise program, which aims at regaining and improving the new hip joint functions. Regular activities can be restored within two to three months. A year is required for utilizing the new hip joint normally.

Risks of hip replacement
There may be several complications as a result of a hip replacement. They include:

Dislocation of the hips
Infection at the surgery wound
Injury to nerves and blood vessels
Difference between the lengths of two legs
Fractures
Alternative
Hip replacement surgery has an alternative type of surgery, which is called hip resurfacing. During this surgery, the damaged surfaces of the bones within the hip joint are removed and replaced with a metal surface. Less bone is removed in this surgery. However, the metal surface may cause complications and health hazards.

Hip replacement is being improved upon with the advent of technology. Stronger and newer materials are being developed for prosthetics, which will allow enhanced joint mobility and a longer wear. New cement-less implants are also being developed. Also surgery assisted by computer is being used for generating an image of the hip joint.

 Hip Replacement - An Overview!

The human body is so amazing yet sometimes, it is delicate. The condition of cervical spondylitis is one of the examples of this being the case. It is also known as cervical disc disease and is reputed to cause a pretty large amount of pain! That being said, it is not as if this pain cannot be reduced. After all, physiotherapy can make almost any situation better and this is pretty much the case with cervical spondylitis, as well!


Neck traction happens to be one of the popular methods prescribed by physiotherapy to help people who are suffering from cervical spondylitis pain. What is done in this process is that the neck is extended but at a very slow rate. While this may not seem like much itself, why this helps is that it goes a pretty long way in taking a lot of pressure off the discs of the spine. While it is true that neck traction is a thing which can be performed at home, it is very important to check with a professional physiotherapist to make sure that the technique that one is practicing is faultless so as to make sure that any painful accidents are not allowed to take place and make the situation worse than it already is!


Physiotherapy is all about engaging in activities which help make the condition better. So, when a person has cervical spondylitis pain, the therapist will spend some time with him or her so that the neck can be slowly adjusted and this will help the range of motion of the person s neck improve by quite a large margin.


There are quite a few other ways to go about relieving the pain caused by cervical spondylitis by making use of physiotherapy. For example, deep tissue massage does have a large number of fans who swear by it. This is also the case when it comes to electrical stimulation. As a matter of fact, both of these are quite popular as a means to get the patient in the right condition for healing exercises to have their full effect.


After all the effort which is put in by the person by the way of exercise, it can be said to be important that he or she makes use of a cervical pillow, which is more commonly known as a neck pillow and a cervical collar, which can help the process of realignment. With correct physiotherapy, cervical spondylitis pain will soon be history!

The Only 4 Moves That Strengthen Your KNEES

Bursitis is a disorder that is characterized by inflammation of a fluid filled sac called the bursa. Bursa is present in between various tissues such as muscles, tendons and bones where friction may occur. This sac cushions the tissues and prevents friction. The usual areas that are affected by this condition are hip, shoulder and the elbows.

The symptoms of bursitis are:
1. You will experience pain in the affected area
2. Tightness and stiffness in the area
3. Local swelling of the muscle
4. Redness of the area
5. Any physical contact with the area causes pain

Bursitis may also occur due to the following reasons:
1. Ageing results in loss of elasticity of the tendons, thus impairing their ability to tolerate any stressful activity
2. Sports such as baseball where you are required to throw the ball with force may lead to bursitis
3. If you do tasks that require kneeling down on a regular basis
4. Sitting on hard surfaces for extended periods of time
5. Abnormalities such as improperly placed joints
6. Inflammation from other conditions such as gout, thyroid disorders and rheumatoid arthritis may lead to bursitis

Treatment
The condition is treated by using a variety of methods such as exercise and medication. Antibiotics are used to treat any underlying infection causing bursitis. Injections may be administered to reduce inflammation in the affected area along with exercises to strengthen the affected muscle. In severe cases, the doctor may resort to surgery to treat this condition.

Prevention
You may use certain preventive measures to stay clear of bursitis. Some of them are
1. Lift with proper form: If you are lifting something heavy, then make sure you keep the spine straight and bend your knees slightly.
2. Take breaks: Don t remain in the same position for long duration, take small breaks and walk around to release the stress from your legs.
3. Exercise: Do strength building workouts to build strength in the joints. Include mobility and flexibility stretches in your routine to keep your joints healthy, thus increasing the range of motion.
4. Maintain optimal weight levels: If you are obese, then take steps to reduce your weight. Maintain a proper diet to check your waistline.
