Avascular Necrosis, also termed as Ischemic Bone Necrosis or Osteonecrosis is a medical condition characterized by the bone death on being deprived of blood. The condition is known to occur in the shoulder, ankles, and knees. However, the part of the body most affected by Avascular Necrosis is the hip. In this article, we will describe the conditions that contribute towards Avascular Necrosis of the hip along with the associated symptoms.

Factors that lead to Avascular Necrosis of the hip
The supply of blood to the bones may be interrupted by a myriad of factors some of which include

1. Certain medical conditions and health disorders such as

Gaucher's disease: A genetic disorder resulting from glucocerebrosidase enzyme deficiency. As a result, glucocerebroside gets deposited in the cells of the macrophage-monocyte system.
Sickle cell anemia: A genetic disorder which results in the RBC's appearing like a sickle cell instead of being round shaped.
Both of these conditions bring about a significant reduction in the supply of blood to the bones resulting in Avascular Necrosis.

Certain inflammatory conditions that may damage the arteries and trigger Avascular Necrosis of the hip include autoimmune diseases, pancreatitis or HIV infection.

2. Extensive and prolonged use of corticosteroids: Often used as non-inflammatory drugs, corticosteroids can play a contributing role, resulting in Avascular Necrosis (non-traumatic). The fatty substances are usually broken down by the body. However, the use of corticosteroids may affect this breakdown as a result of which the fatty substances start piling up in the blood vessels, constricting their size. The constricted blood vessels, in turn, reduces the supply of blood to the bones to a great extent.

3. An injury or a fracture affecting the femur: A hip fracture or a dislocation that affects the upper half of the thigh bone or the femur acts as a potential threat, triggering a traumatic Avascular Necrosis (AVN) of the hip.

In some case, radiation therapy or chemotherapy for cancer can go a long way in interfering with the ability of the bone (weakens the bone) to receive blood, causing bone death.

People who are into heavy drinking stand a greater risk of suffering from AVN. An increased consumption of alcohol causing constriction and narrowing of the blood vessels interfering with the flow of blood to the bones.

Symptoms characteristic of AVN of the hip

Unfortunately, the initial stages of AVN are asymptomatic. However, as the condition progresses into later stages, a person may experience pain and discomfort, particularly while exerting pressure on the bone affected by the condition.
As the bone and the adjacent joints deteriorate and collapse further, a person may experience great difficulty in using the joint altogether.
In some cases, the condition may progress and affect both the hips (Avascular Necrosis Bilateral).

Causes and Symptoms of Avascular Necrosis of the Hip

Treatment of frozen shoulder varies depending on the stage it is at, and how severe is the pain and stiffness. There is no outright cure and the aim of treatment is to keep the joint as mobile as possible. The most effective treatment is that which maintains a good range of movement until the shoulder starts to heal. 

Treatment may Include the following:

1. Shoulder exercises: Regular, gentle exercise can help to keep the shoulder joint mobile. If your shoulder is very stiff, exercise may hurt, and it should only be carried out with the guidance of your doctor or physiotherapist. If you are able to, continue using your shoulder as normal saving' the shoulder can cause the muscle to waste and may make stiffness worse.
2. Painkillers: Over-the-counter painkillers such as paracetamol or prescription-only drugs such as codeine may be taken to ease pain and you should discuss this with your general physician or pharmacist.
3. Anti-inflammatory painkillers: Such as ibuprofen and diclofenac, are often prescribed to ease pain and inflammation. Any medication that you take should be discussed with your general physician or pharmacist.
4. Steroid injections into or near the shoulder joint may be effective at relieving pain and inflammation for a few weeks. However, injections are not a cure, and symptoms may return.


Treatment of frozen shoulder

Problems with the arteries and veins present in the hands or legs can lead to vascular disorders. The arteries carry blood from the heart to other parts of the body in order to deliver nutrients and oxygen. The veins carry the blood back to the heart, after the nutrients have been used up. If these blood vessels of the arteries or veins become blocked or narrowed, it can lead to a vascular blockage.

A vascular blockage that occurs in the hands or legs comes under the category of Peripheral Artery Disease or PAD. These type of disorders are less common in the upper extremities of the arms or hands than in the lower extremities of legs. Few of the signs for the same are:

Pain and difficulty in movement due to decreased blood flow
Numbness or weakness of leg or fingertips
Sores on the toes or feet
If the blockage is deep, symptoms of redness, swelling, extreme pain or cramping can be experienced
Abnormal color changes in the fingertips
Ulcers or wounds that don t heal
Skin sensitivity problems when in cold temperatures
How can it be diagnosed?
The blockage can be detected by various methods namely-

Physical Examination   Your doctor may find decreased pulse at armpit, wrist or fingers, full veins, masses, wounds or gangrene.
Doppler or Ultrasound examination to determine the blood flow in the arteries and veins
MRI Scan of the affected area to pay special attention to the blood vessels
Cold Stress Test
Arteriography to show clear blood vessel details
Angiography to map blockages and narrowing of the arteries
What are the Risk Factors for Peripheral Artery Disease?
An individual is at risk for developing vascular blockages in the hands or legs if one or more of the following factors are present:

Smoking
Diabetes
Heredity Factors   A personal or family history of blood vessel disease
High blood pressure
High cholesterol
Aging   People aged above 50 years and older are more prone to vascular blockage
Can it be treated?
Treatments for vascular blockage can vary depending on the age, cause of the blockage, intensity and overall well-being.

Treatments can include:

Self-care   Reducing risk factors and making lifestyle changes to quit smoking, sedentary life or diabetes, blood pressure and cholesterol management can reverse symptoms of vascular disease.
Medications   A variety of drugs can be prescribed to lower the risk and progression of narrowing blood vessels or prevent blood clotting.
Interventional Procedures   Minimally invasive surgery like saloon angioplasty, stenting or removal of artery plaque build-up.
Surgery   If the blockage is severe, surgery may be performed to lessen the vessel narrowing, reconstruct the artery or tie it off, depending on the circumstances.

Pain in the Hands or Legs!

Pain management is an issue that stares back at mankind, irrespective of the underlying health condition. Whether it is a headache or a back pain, burn or fracture, heart attack or cancer, pain is always a symptom. In some cases like migraines, cancer, etc., the pain is chronic and the patient needs to be constantly on the vigil to know when an attack will ensue. This has also put high pressure on the medical fraternity to identify ways that can provide relief to these people. Various methods have been identified, and one of them is the electrotherapy.

What is done?
A few electrical impulses are directed at the area of the pain using a hand-held device. This is similar to providing electric shocks of mild intensity to the affected area (forehead, low back, neck, etc.). What this does is stimulate the nerve endings, improves circulation and muscle strength and promotes bone growth and tissue repair. The end result of all this is overall improved functioning and pain relief. Depending on the actual condition, the sessions will have to be repeated. In some patients, the electrotherapy is used in conjunction with other therapy so that they can go about their routine exercise and pain relief.
The sessions may also have to be repeated as most often these are used in individuals with chronic pain. They are also helpful in providing relief during the acute attacks.

How does it work?
The most common form of electrotherapy is known as TENS, which stands for transcutaneous electrical nerve stimulation. The area to be treated is cleansed with spirit and then small sticky pads are applied through which the electricity is passed. A hand-held device is used, through which electrical impulses are passed to the skin, which stimulates the nerve cells to provide relief from pain. It causes a vibrating and tingling sensation in the treated area. It is believed that it blocks the nerve impulses and therefore provides pain relief. Another theory states that they promote the release of endorphins which are natural painkillers; it is also very effective in case of migraine and sciatica and neck pain where the chronic pain is coupled with acute spurts.

With narcotic painkillers having various side effects, techniques like electrotherapy are gaining popularity. A small catch also is that it does not work for everybody and in most people with back pain, fibromyalgia, and migraines, requires repeat sessions for relief. The cost of each session also needs to be considered against the extent of relief achieved. However, for those whom it works, it is a very good technique for chronic pain control.

Electrotherapy - How It Can Help In Managing Pain?

Are you prone to slipped disc problem? + the ideal way to treat it

A slipped disc, also known as a prolapsed disc or herniated disc, is the term given to the phenomenon that occurs when a cartilaginous disc found between the vertebrae in the spine becomes slightly displaced or protrudes, thereby pressing on the nerves in the adjacent areas and causing back pain.
This happens when the soft inner part of the disc, known as nucleus pulposus, bulges out through a weakness in the exterior part of the disc. A prolapsed disc usually occurs in the lower region of the spine and can be of varying sizes. There might even be the development of inflammation around the disc in some cases.

Who is likely to get affected?
Most cases of herniated disc occur in patients between the ages of 30 and 50. The number of men affected is twice as many as the number of women.
Although the root cause of this problem is not yet known, there are a number of factors that may trigger it. These factors include working at a job that requires a lot of lifting, an occupation that involves remaining in a seated position for a long time, weight-bearing sports, obesity, smoking habits and increasing age.

Effective ways of treating the problem
The different methods that are commonly used to treat the problem are:
Medications
There are many different kinds of medicines that are effective in providing relief. These include painkillers, muscles relaxants, anti-inflammatory pills, etc.

Spinal injections
A number of spinal injections are used to treat slipped discs. The injection is done at the opening where the inflamed nerve roots are found and reduces pain, swelling and irritation in the area.

Radiofrequency ablation
This procedure makes use of an electrical current produced by radio waves to reduced pain and sensitivity in the affected area.

Ozone discectomy
As opposed to the surgical removal of the prolapsed disc, this new process makes use of an ozone-oxygen mixture that is injected into the spine to treat the problem. Many international studies have proved its superiority to traditional methods and surgeries.

Those affected by this problem are advised to keep exercising and continuing with their everyday activities as best as possible.

When is your pain chronic?

Your pain is chronic if it last for more than a period of six months. Chronic pain is a long-term pain whose nature can vary from mild to excruciating, and it may trouble you either continuously or at short and regular intervals. Chronic pain is so dangerous that it does not only cause discomfort and inconvenience but also robs you entirely of your capacity to work for a long time.

Chronic pain can occur in a number of organs of the human body like head, joints, back, shoulders, neck etc. In fact, pain in any part of your body can turn into chronic pain. Here are a few symptoms that can help you identify if what you are going through is, in fact, chronic pain:

- persistent and severe body pain

- burning sensation accompanied by the body pain

- fatigue and sleeplessness

- weak immune system

- stiff and sore joints

The 4 types of chronic pain disorders that you should be aware of are:

1. Nociceptive pain

The pain that affects the soft tissues of the body such as the skin and the muscles or the organs that have sensory nerves present in them is called nociceptive pain. The sensory nerves, known as nociceptors can detect the stimuli of pain and send information to the brain and the spinal cord for interpretation. The pain could be either somatic (originating in the outer body) or visceral (originating in the internal organs).

2. Neuropathic pain

This pain is caused when the nerves stop functioning normally. It is caused due to nerve disturbances that result in pain stimuli being spontaneously transmitted to the brain and spinal cord. If you are suffering from this type of chronic pain disorder, you will feel a sharp, shooting and stabbing pain. Neuropathic pain can also be caused due to the formation of neuroma (abnormal growth of the nerve tissue).

3. Psychogenic pain

The pain that is caused by psychological disorders like depression and anxiety is known as psychogenic pain. Sometimes this pain can be accompanied by physical complications like fatigue, body pain and muscle weakness.

4. Idiopathic pain

The pain that exists even though there is no physical or psychological cause for it is known as idiopathic pain. This pain is more common in people who have suffered from a pre-existing painful disorder. Some common examples of idiopathic pain are fibromyalgia (intense pain all over the body) and tmj disorders (pain in the jaw area).
