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

Did you know that in addition to your diet, exercise is one of the best ways to make sure that you never lie on a hospital bed with a surgeon treating you for a bone disorder? Medical expertise has constantly pointed out to the fact that regular exercise makes your bones less likely to suffer from wear and tear during old age.

Swimming is a cardiovascular exercise, which is also known for its calorie burning capabilities. It is also very effective is incinerating fat and keeping your skeletal system healthy. Whereas walking and jogging and running certainly build your bones as they are weight bearing exercises.

One of the deadly diseases caused by the bite of an infected mosquito is Chikungunya. If you suddenly experience unbearable joint pain with symptoms of fever, consult a doctor immediately. Even the name Chikungunya etymologically means "to become twisted". If you are having the aforementioned symptoms, there is a high chance you are suffering from Chikungunya.

Symptoms of Chikungunya
Chikungunya affects your body within 3-4 days of the mosquito bite. The first sign of Chikungunya is sudden fever, which causes mild tremors in your body accompanied by severe pain and swelling of the joints. A headache and pain in the muscles are other two symptoms of this disease. The most glaring indication that you are suffering from it is the excessive joint pain you experience. This pain usually lasts for a few days to a couple of weeks. If left untreated, this disease can prove to be fatal. 

1. The joint pain will have a paralyzing effect on your body resulting in extreme pain.
2. Your finger joints and foot exhibit signs of swelling, causing severe pain.
3. You will experience pain in your hip, wrists and elbows.

Other symptoms of the disease include neurological and mild cardiac complications. You may even complain of having an eyesore. Also, there are chances of you suffering from gastrointestinal problems. However, none of these symptoms will be as severe as the excruciating joint pain you experience.

Some preventive measures can be taken, them being:
a. Drink plenty of water to keep yourself hydrated.
b. Get plenty of sleep. It might be impossible for you to sleep especially when you are having body aches. Thus ask your doctor for some painkillers which will let you rest.

Suffering From Severe Joint Pain? It Could Be Due to Chikungunya

The deltoid muscle is situated around the shoulder joint that makes up the shoulder. It is classified into three parts - front, side and rear deltoids. It is one of the most frequently used muscles in the body, its major functions are abduction and forward elevation of the arm.

Causes
A deltoid strain is a condition where you experience pain and tenderness in the shoulder area due to various causes like overuse of the deltoid muscle. It is very common in weightlifting and various sports such as cricket. It may even lead to partial loss of function in the deltoid muscle. Deltoid strain may be caused due to overworking of the muscle without adequate rest. It may also be caused due to lengthening of the deltoid muscle under stress or direct trauma to the muscle.

There are three types of deltoid strains

Grade 1 deltoid strain: It is characterized by tight muscles with some possible swelling. There may be mild pain when you use your shoulders for any activity.
Grade 2 deltoid strain: This strain is a result of a major injury to the deltoid muscle; there may be visible swelling and pain while carrying out activities that require movement of the shoulder. Lifting your arm to the front or the sides becomes difficult and painful.
Grade 3 deltoid strain: This form of deltoid strain is the most severe of the three; it may cause the shoulders to become immobile. You usually will experience excessive pain and severe swelling. You might not be able to move your arm and carry out any activity that requires the shoulders.
Diagnosis
The diagnosis of a deltoid strain starts with a physical exam where the doctor will understand the symptoms of the deltoid strain. Various imaging tests such as x-rays may be required for the diagnosis. The basic treatment for shoulder strain comprises of the RICE protocol (rest, ice, compression and elevation) which is used to treat grade 1 and grade 2 strains. Grade 3 strains may require surgery in addition to the above treatment methods. In case of excess pain, the doctor may prescribe non-steroidal anti-inflammatory drugs to ease the pain.

All About Deltoid Strain!

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.
