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

Hip replacement is a surgery in which a specialist doctor surgically removes an agonizing hip joint afflicted with arthritis and replaces it with a man-made joint usually produced using metal and plastic elements. It is usually done when all other treatment choices have been tried and have proven unsuccessful in providing satisfactory pain alleviation. The technique is to mitigate the pain in ahip joint, in order to make walking and other physical exercises easier.

The surgical procedure is as follows:

Hip replacement surgery can be performed generally or by utilizing what is called a non-obtrusive method. The primary difference between the two methodologies is the number of entry points needed for the surgery.
During standard hip replacement surgery, you are given general anesthesia to relax your muscles; this will keep you from feeling any pain during the surgery or being awake during the surgery. A spinal sedative might be given to counteract pain as an add-on option.
The specialist will then make a cut at the edge of the hip and move the muscles connected to the highest point of the thighbone to uncover the hip joint.
Next, the ball part of the joint is taken out by cutting the thighbone with a saw. At this point a fake joint is attached to the thighbone using a material that allows them to stay intact.
The specialist then readies the surface of the hipbone - evacuating any harmed ligament - and joins the substituting attachment to the hipbone.
The new ball part of the thighbone is then embedded into the new joint part of the hip. The specialist then reattaches the muscles and shuts the entry point.
There are some things you need to keep in mind and be attentive about, post the surgery. These are as follows:

You will probably remain in the healing facility for four to six days and may need to remain in bed with a pad between your legs to keep the new hip joint set up.
A seepage tube will be set in your bladder to help you urinate without having to walk to the bathroom.
Non-intrusive treatment usually starts the day after surgery and within the days you can go around with a walker or a walking stick.
You will continue with the non-intrusive treatment for quite a long time which could be a number of months post the surgery.
For anywhere in the range of six to twelve months after hip replacement surgery, rotating or putting pressure on the operated leg needs to be limited to a great extent. You need to likewise not cross the operated leg past the midline of the body nor turn it inwards.
You cannot twist the hip past ninety degrees. This includes both twisting forward at the abdomen and crouching.
Your physical advisor will tell you the methods and equipment that will help you comply with the above rules and precautionary measures while performing every day exercises.

Hip Replacement - Things You Must Keep In Mind!

A fall or an injury is among the most common causes of a fracture. For a fracture to heal; the bones must be set in the correct position and a cast may need to be worn so as to hold them in place. This allows the bones to grow new tissue and bridge the break. The food you eat can help you speed up this process. Some of the best foods to build strong bones and help a fracture heal are:

Milk: Milk is one of the richest sources of calcium and vitamin D. It is also rich in proteins. These three elements are crucial to building strong bones. Proteins help the body release amino acids which in turn come together and create new tissue for the bones. Calcium is, of course, the building block of our bones. However, it is vitamin D that enables the body to absorb this calcium and utilize it. If you do not like the taste of milk, you could substitute it with yogurt. This dairy product is considered equally rich in proteins, calcium and vitamin D. In addition, it also contains amino acids such as glutamine and lysine that helps the bones absorb calcium.
Kale: Kale is known as a superfood. One of the reasons for this is the amount of calcium it contains. Kale is one of the few vegetables that are rich in this mineral. Thus, lactose intolerant people can get their required calcium from this vegetable. Kale can be eaten raw or cooked. Kale can also be juiced. However, to benefit fully from the vitamins and minerals in this vegetable, it is best to eat it raw.
Spinach: Spinach is another green leafy vegetable that is rich in calcium. It also contains zinc. Zinc helps stimulate the chemical reactions needed to bind calcium and other minerals together to create new bones. In addition, spinach is also a rich source of vitamin K. While this vitamin does not play a direct role in healing bones, it helps speed up the healing process.
Broccoli: Broccoli is a cruciferous vegetable that is rich in vitamin K1. This is very beneficial to your overall health and bone health. Vitamin K1 aids in the mineralization process of fusing broken bones together and building new bone tissue. Thus, it helps the bones set correctly.
Citrus Fruits: Fruits such as oranges are chock-full of vitamin C. This nutrient helps build a strong immune system and aids in the fracture healing process. Vitamin C also helps the body create collagen that surrounds the broken bones and allows it to heal faster.

Food Items That Help You Recover From Fractures!

A sprain refers to a break or a tear in any of the ligaments of your body. A ligament is a band consisting of tissues that connect the bones at any given joint in our body.

A strain on the other hand refers to a tear or a break in the entire muscle itself or a tendon (the band of tissues that connect the muscle to the bones).

Occurrence
Sprains usually take place due to unforeseen incidents like falls, accidents, and such other things that forces the body part to go out of its normal position. The most common types of sprains that people suffer from are ankle sprains which affect about 25,000 people every day on a worldwide basis.

Strains usually happen when you twist a whole muscle or a tendon. This condition most commonly occurs in cases of sportspersons who are engaged in contact sports like hockey, football, rugby, and such others.

Symptoms
The identification signs of sprains and strains are mostly very similar, which are listed below:
1. Pain and discomfort in the joints
2. Visible swelling or inflammation seen on the joints
3. Bruising of the affected area
4. Tenderness and softness of the affected joint

The overall intensity of the above mentioned symptoms might differ basis on the severity of the condition that is directly proportional to the nature of injury that you have faced. Some pains are so light that it may not affect your daily routine at all, whereas some pains are so intense, that you might not be able to move your affected joint at all.

Treatment
Some of the common methods to cure a sprain or a strain are listed below:
1. Rest the area which is affected
2. Apply ice bags or cold compress to soothe the pain
3. Compress the affected joint using a compression tape
4. Place the affected joint on an elevated area to speed up the healing process

Sprain Versus Strain

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!

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.
