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?

About 80 percent of people all across the globe experience lower back pain at some stage in their lives. It is one of the most common reasons why people miss their work and appoint a physiotherapist. But lower back pain is an ailment that can be avoided with proper knowledge and some back exercises. In case your lower back pain is not under control and you have been neglecting it, you are susceptible to acute pain, sciatica, nerve pain and pain in other regions caused from a pinched nerve. Long-term pain in the back portion can lead to permanent ailments like degenerative disc disease or spinal stenosis.

Probable causes of lower back pain
Severe pain in the lower back region can be caused due to a herniated disc, back muscle pain, ligament strain or any other non-specific pain. An individual may also suffer from lower back pain due to systemic conditions like rheumatoid arthritis, fibromyalgia or ankylosing spondylitis. Though these causes are very common in most people suffering from lower-back pain, the diagnosis varies from person to person and to ensure the best care to alleviate the pain, you must consult a responsive musculoskeletal physiotherapist.

Stages for assessing and treating lower back pain
Managing the back pain is the primary objective of physiotherapy. In reality, back pain is the final symptom that is developed and the first thing that must be addressed.

Stage I
Back pain relief: The physiotherapist is going to use different types of tools and items to help the pain subside along with the inflammation. These include electrotherapy, acupuncture, ice application, soft-tissue massage and deloading taping techniques. Sometimes the physiotherapist may also recommend an anti-inflammatory drug if the pain is intolerable.

Stage II
Restoring normal strength: With the settling of pain and inflammation, you are more susceptible to injury because though your pain has subsided, your ligaments and muscles are weak. Your doctor will aim at restoring normal motion of lumbar spine, muscle endurance and strength, proprioception, balance and walking abilities.

Stage III
Restoring full body function: Depending on your daily chores and activity, your physiotherapist will aim at restoring the function of your back portion to keep you safe while performing the chosen activities. For some, it may be taking a slow walk around the park while for others it may mean taking part in some sports activity.

Stage IV
Preventing recurrence: Your physiotherapist will rehabilitate you to prevent further occurrence of this excruciating pain by suggesting proper postures, exercise and core muscle workout.

Each of these stages are important to help you get rid of severe back pain and with daily exercise, you can regulate your body and spare yourself from recurrence of this lower back pain.

Treating Chronic Lower Back Pain

Back pain is one of the most common debilitating disorder in the world today. The pain affects 90% of people at some point of their lives. Human back comprises of various structures (see figure) which are nerves, bones, muscles, ligaments, and tendons, any or all of which can be a source of pain. Once back pain occurs, it may become chronic (more than 4 weeks) and you shall need to consult a pain physician for relief and accurate diagnosis.
Since prevention is always better than cure,  you can save yourself from having back pain if you follow these basic tips.
Regular Exercise in Correct Form: Regular exercise is important to maintain proper muscular strength of the back. Human back is supported by several big muscle groups (see figure). They serve two functions - one is to facilitate the posture and movements of the back itself and the other is to help movements of the rest of the body appendages (arms, head, pelvis and legs).The health of these muscle group is important to take stress off the spinal bones and maintain proper function. Most of these muscles are red muscle fibers as they need to maintain their activity for prolonged periods of time. Just to give you an idea - your biceps (arm muscles) have to work only when you bend your arm. But your back muscles have to function all the time - whether you sit, walk, stand or even sleep. But the point is what kind of exercises are good for your back? The best exercises for back include body weight low impact aerobics like brisk walking, swimming, stationary bicycling, extension exercises and yoga. What is important to remember while doing these exercises if that you need to be gentle in your movements and achieve correct "form" - this is possible if you can ask someone (preferably a trainer) to observe and point out whether the back stays straight during the exercise. It has been seen that arching and excessive bending is associated with injury to the back while exercising.
Stay Hydrated and Eat Natural Nutritious diet:The inter vertebral discs contain 70 - 80% water. The muscles and tissues have 60% water content. Therefore, it is important to stay hydrated. In addition, you must eat a nutritious diet consisting of green leafy vegetables, good protein source and just enough carbohydrates. Deficiencies of essential nutrients like Vitamin D can result in diseases like osteoporosis. Another important aspect is to maintain body weight within healthy limits. This is very important as increased belly fat is linked to increased back pain due to mechanical factors.
Lift objects correctly and maintain proper posture:While lifting objects, keep them as close to body as possible. Do not slouch or bend excessively while lifting. Just keep your back straight at all times. You may bend your knees a little if required (see figure). Think before you lift and get help if needed.
While working, you must not sit for more than 45 minutes at a stretch. Walk for two minutes, go to a colleague's desk and say hi or even just drink some water or visit the washroom. Humans evolved as hunter - gatherers and our bodies are more adapted to walking / standing than to sitting for prolonged periods. Those of you who travel more and have to sit for long periods of time also need to follow above tips - avoid prolonged sitting in same posture.While exercising, improper position can do more harm than good. Therefore, proper form and posture is a must.
Bonus tip: Avoid cigarette smoking and those who smoke cigarettes to decrease your chances of having degenerative disc diseases leading to chronic back pain early in life.
Word of caution to prevent permanent damage: In case of back pain, which is not responding to home remedies or over the counter painkillers, please contact a Pain Physician to pinpoint the diagnosis and appropriate management.

3 Essential Tips to Prevent Back Pain

Knee is a hinge joint where the lower leg bone tibia meets the thigh bone femur. During osteoarthritis, cartilage or ligament defects and degenerative arthritis, knee replacement surgery is recommended world-wide to get relief from extreme pain. Knee replacement surgery, also known as knee arthroscopy, is a surgical procedure, in which the affected knee joint is replaced with synthetic material. The most likely candidates for total knee replacement are the patients with severe destruction of the knee joint coupled with progressive pain and impaired function.

Modern technological advances have made computer assisted knee replacement surgery extremely popular around the globe. In this surgery, the surgeon is assisted by a computer to remove the optimum amount and angle of the bone, which otherwise is done by inspecting manually. This is an excellent example of surgery through small incision and it eliminates the chances of human error. A perfect alignment and balance is achieved and hence longevity is also increased to 20 - 30 years. Knee replacement surgery is also specific to gender as the anatomy of male and female patients is different.

There are many types of knee replacements, most common being the total knee replacement or Total Knee Arthroplasty. In addition, there is partial knee replacement, bilateral knee replacement, revision knee replacement and knee arthroscopy.

In knee replacement surgery, the worn out surfaces of joints of knee are replaced with artificial implant of plastic and metal. The lower end of the femur bone is removed and replaced with a metal shell. The upper end of the lower leg bone (tibia) is also removed and replaced with a channelled plastic implant with a metal stem. A plastic ball is also added under the kneecap depending on its condition. These artificial components are commonly referred as prosthesis. The design of these highly flexible implants replicate knee, with the rotating knee replacement implants assist in backward and forward swing of the legs.

Patients whose knee joints have been damaged by either trauma or progressive arthritis should consider total knee replacement surgery. Post-surgical hospital stay after knee joint replacement is usually three to five days. The surgery has a very high success rate and shows dramatic improvement after a month. This improvement is most notable one month or more after surgery. The pain caused by the damaged joint is reduced significantly when the new gliding surface is constructed during surgery. Initially, patient will walk with the help of a walking aid until the knee is able to support full body weight. After six weeks, patient can walk comfortably with minimal assistance. Patients with artificial joints are prescribed to take antibiotics during the course of any elective invasive procedures including dental work. Physiotherapy is an essential part of rehabilitation and it will increase the muscle strength and patient can enjoy most activities, except running and jumping.

Knee Replacement

Rotator cuff is the name given to four muscles and their tendons, which keep your arms in your shoulder sockets, allowing you to lift your arms and do day-to-day stuff like combing your hair, cutting vegetables etc.

The shoulder joint is a very important joint of the body and this is why any tear that happens in the rotator cuff can be devastating.

Causes

Tears can happen in rotator cuff due to a number of factors like injury and degeneration due to age. Tears that happen due to an injury to the shoulder are called acute. Degenerative tears are tears that happen due to degeneration of the tendon over time.

Common causes of degeneration are lack of proper blood circulation, which impedes the rotator cuff s ability to repair itself. Repetitive stress is another cause where we stress the tendon by repeating the same shoulder motions again and again while playing games like tennis, cricket etc. and doing jobs that require us to extend our arms upwards a lot. Lifting heavy objects can also lead to tears.

Symptoms

Chronic shoulder and arm pain are good reasons for you to see your doctor. If you suffer from pain in your shoulder at rest, while sleeping on the affected shoulder or pain while lifting and lowering your arm, then there is no time to wait.

The doctor will do a physical examination by moving your arm in different directions. He may follow it up with X-rays and MRI to check how big the tear is in your rotator cuff.

Treatment

Once confirmed that you indeed have a rotator cuff tear, your doctor will start the treatment. The goal of any treatment is to reduce pain and make your shoulder joint work properly again.

Nonsurgical Treatments: 

Nonsurgical treatments include rest, using of a sling to protect the shoulder and modifying your daily activities. This means you may not be able to do activities that cause shoulder pain. Your doctor can also prescribe pain and anti-inflammatory medicines. Strengthening and physical therapy bring up the rear of this type of treatment.

What you must remember is that nonsurgical treatment relieves pain and improves function in the shoulder, but does not improve shoulder strength. The size of your tear may also increase over time.

Surgery: 

Surgery, which attaches the rotator cuff to your bone, is done if you suffer from continuous pain and symptoms over a year or so. If you have a large tear, conservative treatments will not work and surgery will have to be resorted to. 

If you have been suffering from chronic shoulder or arm pain, waiting and watching is definitely not an option. You must visit an orthopedic surgeon at the earliest. Remember, if treatment is not started soon enough, your rotator cuff tear will get larger and will require only surgery.

Rotator Cuff Tears: What Are My Options?
