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?

Facial paralysis can happen due to many factors. Sometimes inflammation develops around the facial nerve as it passes through the skull from the brain. This presses on the nerve and makes it stop functioning. As the nerve stops functioning, so does the muscle it controls.


This is what happens in Bell s palsy, the most common cause of facial paralysis.


Bell s palsy can happen to anyone and its cause is, hold your breath, a viral infection. Herpes zoster, Varicella zoster and HIV viruses can cause Bell s palsy.


Bell's palsy is a common cause of a facial paralysis but there are many others too that affect or damage facial nerve. These include head injury, sarcoidosis, lyme disease, growths in the ear, tumours in the parotid gland, brain tumours and stroke.


The weakness of the face usually one-sided is a symptom of Bell s palsy. The face may droop to one side, chewing food is also tough, drooling, dry eyes and difficulty wrinkling forehead and speech are other symptoms of Bell s palsy, the most common reason for facial paralysis.


Treatment:
The type of therapy you receive for facial paralysis will depend on its cause. It will also develop on how long you ve suffered from facial paralysis and the extent of damage to the facial nerve.


Your physiotherapist can help and so can speech and language therapists to deal with the issue.


In physiotherapy, a treatment called 'facial retraining' with facial exercises helps with facial palsy. It is important that you seek help from a therapist who specialises in facial rehabilitation only.


This is what you can expect from facial rehabilitation therapy-
Exercises for eye care
Exercises for dry mouth management
Exercises to make drinking and eating easier
Speech therapy
Your physiotherapist will educate you on how the facial nerve works and how it recovers. This is important to make you recover. A home therapy programme plays an important role too. It includes massages to keep face muscles mobile and healthy, stretches to lengthen muscles, exercises to help re-learn balanced facial movements and relaxation of your facial nerve and muscles.


The physiotherapist will work on your facial movement to make muscles fit. The basic idea is to slowly rewire the brain-to-nerve-to-muscle pathway. The physiotherapist s first step is to retrain you to do correct movements voluntarily, while mentally focusing on the movement.


Physiotherapy may take months but keep at it to recover completely, especially the home exercises.


Injections of botulinum toxin or Botox also help especially if you suffer from spasms in facial muscles. Surgery is also an option for chronic cases.


Remember that exercises should be done gently as well as daily to reap benefits. Always do these exercises with the help of a therapist only. Doing exercises by yourself can be counter- productive.


Facial Paralysis - How Can Physiotherapy Help You Get Better?

While it may be obvious that no form of pain is welcome, it can be said that pain which is felt on account of being affected by sciatica is especially unwelcome. Taking that into due account, the good news is that physiotherapy can go a long way in helping by improving this sort of pain.

The longest nerve in the whole human body is the sciatic nerve, so it can be expected that when there is trouble with this nerve, the pain would be pretty significant. The leg pain which is caused to a person when this nerve happens to be getting pinched is known as sciatica.

There is a range of treatments when it comes to how something as painful as sciatica is to be solved. Now, while it is true that a solution such as making sure there is an amount of bed rest which is sufficient is very important, to say the very least, it is often the case that the person with sciatica would like his or her recovery to be hastened.

In order to make sure that this is the case, physiotherapy is quite useful. There are various forms of physiotherapy which can be made use of, and the decision as to which sort of physiotherapy a person would be best suited to would obviously be part of the subjective assessment of the person by a practitioner who is well qualified and experienced.

Some of the solutions when it comes to physiotherapy being used in order to treat sciatica are quite innovative, to say the very least. For example, there is physiotherapy instrument mobilisation, which is also known as PIM. What this entails is that a mechanical spring-loaded instrument is used in the process which serves the purpose of mobilising the spinal cord of a person along with his or her peripheral joints.

One form of physiotherapy oriented treatment which is used to address the issue of sciatica is real-time ultrasound physiotherapy. It can be said that this is not close to as cutting edge as physiotherapy instrument mobilisation is but it does serve as a rather dependable and useful way to battle sciatic pain. This form of physiotherapy makes use of ultrasound technology to analyse how the muscles function and then using that as a basis to create a list of physiotherapy exercises to be done by the person who is having sciatica. Rather than medicines, physiotherapy improves sciatica by getting a person to use oneself!

How Can Physiotherapy Help With Sciatica Pain?

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.

Arthritis is a painful joint condition that leads to pain and stiffness as well as lack of proper mobility due to inflammation and swelling. Usually, an orthopaedic specialist will prescribe anti-inflammatory and pain relieving medication for this condition, but there are various things that you can do to ensure that this condition does not become a debilitating one in the long run. One of the best ways of doing this is by limiting your diet in certain ways when it comes to inflammation producing food. 

Here are a few types of food to avoid if you are suffering from arthritis.

Fried food: Fried and processed food is packed with too much of salt in order to better preserve it so that it has longer shelf life. Also, the use of oil in order to deep fry can have a detrimental effect on the inflammation that is already causing problems for your joints. Therefore, it is best to avoid fried, fatty and processed or packaged food that has been frozen for too long.
AGEs: When we speak of AGEs, we are not talking about the number of birthdays that you have celebrated. AGEs are actually Advanced Glycation End products that are a toxin released by food when it is heated, grilled, fried or pasteurised. These toxins can render damage to the proteins in your body. Once this process starts, the body retaliates by sending forth cytokines which are basically inflammatory messengers. This can lead to inflammation and arthritis.
Sugar: Sugar and other refined carbs also have a large amount of AGEs as discussed above. These types of food should also be avoided by patients suffering from arthritis. Also, artificially sweetened drinks and too many baked goodies should be avoided by these patients.
Dairy products: Owing to a certain kind of protein that most dairy products contain, these kinds of food are considered harmful for patients of arthritis. These proteins can encourage inflammation and irritation of the tissue that surrounds your joints. Switching to a vegan diet is considered helpful for arthritis patients.
Alcohol: Excessive drinking is a major problem that can aggravate your arthritis situation. Smoking and drug abuse also leads to such problems. Drinking excessively can lead to the development of gout.
Corn oil: This kind of oil is a part of most packaged, processed and fried food. It also leads to inflammation. Arthritis patients should switch to omega fatty three oils which can be found in fish.
Taking care of your body is a matter of maintaining a good diet with lots of activity that will be congenial for your condition. This will also help in keeping the painful symptoms of arthritis away.

Arthritis - 6 Foods You Must Avoid!

Spine deformity refers to an abnormality of the shape, alignment, or formation of the vertebral column. The spine in the human body is composed of small bones or vertebrae, stacked on top of another. A healthy spine, typically, has gentle curvatures. A displacement or exaggeration of the spine leads to deformities.

Types of spine deformities:

The three major forms of spine curvature deformity are-

  Lordosis - Causes the lower back to turn inward
  Kyphosis - Leads to forward rounding of the back
  Scoliosis - Causes the spine to curve sideways

What are the causes of spine deformity?

The following conditions may cause the spine to be misaligned-

  Achondroplasia - A disorder, which impedes the normal growth of the bones, thereby resulting in short stature or dwarfism
  Spondylolisthesis - When the vertebrae in the lower back slip forward
  Osteoporosis - When the vertebrae become fragile and prone to fractures
  Scheuermann s disease - A developmental disorder of the spine that leads to abnormal growth of the upper back
  Spina bifida - A congenital disorder where the spinal column does not close completely while inside the womb

Symptoms associated with deformed spine:

Signs and symptoms of a deformed spine include-

  Uneven/misalignment of the shoulder and hips
  Uneven shoulder blades (one side is slightly higher than the other)
  Slight bending of the head over the body
  Difficulty in movement
  Discomfort and back pain

How is the condition treated?

The treatment of the condition depends on the severity of your spine deformity. Anti-inflammatory medications and drugs are prescribed to manage pain and discomfort associated with spine deformity/curvature. However, these cannot correct the deformity completely.

Severe cases of spine deformity need another line of treatment.

  Bracing - Back braces are recommended for children and adults alike, depending on the degree of curvature. This can help prevent the condition of your back from worsening.
  Body casting - The doctor places a cast that starts from the shoulders and goes all the way down to the lower trunk. This provides adequate support to the spine and strengthens the back.
  Spinal instrumentation - The surgeon will attach instruments like rods, hooks, and wires to the spine to keep the bones aligned following a spinal fusion.
  Artificial disc replacement - The surgeon replaces degenerated discs in the spine with artificial devices.
  Kyphoplasty - The surgeon inserts a balloon into the spine to stabilize and realign the deformed spine and relieve you from the pain.

Following the treatment, patients with spine deformity are usually advised to go for physiotherapy sessions. Physical therapy and exercise can help you build muscle strength and increase flexibility.

Deformity of the spine is a difficult condition to live with. Not only does it restricts your normal movement but also places you at risk of other musculoskeletal disorders. Therefore, it is imperative that you get the condition treated by a specialist.
