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

A small piece of bone is known as a fragment and it is very common that an avulsion fracture also tends to damage the protrusions of bone to which the tendons attach. This basically means that the tendon or ligament will come away from the bone and it will take a small piece of bone with it. It is sometimes very hard to find out what type of injury you have and this is why knowing the causes and symptoms of an avulsion fracture are very helpful in determining exactly how severe the injury is. 

Here are the causes of an avulsion fracture:

Explosive landing: Athletes who tend to jump or land with great impact tend to get these most commonly. Therefore, it is crucial for your health that if you participate in such sports, you do follow the correct method of jumping.
Explosive extension: Similar to how an athlete landing ferociously can get an avulsion fracture, someone who is extending the legs very violently and explosively during an exercise can also get an avulsion fracture. This is because the bone getting extended could very well damage the protrusions to which the tendons are attached. 
Symptoms
These are the two main causes of an avulsion fracture. There are not many symptoms of an avulsion fracture. This is because an avulsion fracture can only be determined by an MRI or by an X-ray scan. Therefore it is nearly impossible to diagnose that you have an avulsion fracture without looking at the results of the tests performed on the part of your body. However, the way you got the fracture and especially the details of it are very good indications of whether you have an avulsion fracture or not.

Avulsion Fracture - Common Causes Behind it

The joints and bones of the body are connected by fibrous band of tissue called as a ligament. When these ligaments are over stretched or are subjected to any injury that could cause tearing of the ligament and a sprain of the ligament happens. Sprains usually occur at the ankle joint, knee joint or the shoulder, since these areas have a connection of bones at a joint. 

During movement, the ligament functions to stretch or expand and move back to its original position. However, sometimes due to an over-stretch of the ligament, it gets pushed or expands beyond its usual position. A sudden twisting movement of the ligament can also cause a sprain. 

While walking, any abnormal movement of the leg can cause a sprain, hence, the ankle joint is the most common location affected by a sprain. Sports injuries are a common causative factor of sprains. In accordance to the body part involved frequently in playing sports, a wrist sprain or an ankle sprain is a common finding. 

Dancers are also prone to frequently sprain their ligaments. If a sprain occurs at the wrist joint, it can also lead to cause the Carpal tunnel syndrome, which leads to the numbness of the wrist joint. Moderate to severe pain around the affected joint, presence of bruising in cases of an injury, swelling around the affected joint and difficulty in movement are the common symptoms of a sprain.



There can be a popping sound heard during an injury to the joint, which indicates a sprain. Sprain of the joint can cause other complications too. If there is an involvement of the nerve in the injury, there can be an associated numbness and tingling sensation at the affected area. A physician performs physical inspection of the area while looking for the symptoms of sprain. If the injury involves a larger surface area and is causing severe pain, an MRI or X-ray can be ordered to detect for the ligament or bone involvement, respectively. 

Classification of sprain can be enlisted as follows: 

Grade 1 sprain (mild): Slight stretching and little damage to the fibers of the ligament. 
Grade 2 sprain (moderate): Includes partial tearing of the ligament.  
Grade 3 sprain (severe): Includes complete tearing of the ligament.  Prevention of a sprain can be achieved with certain measures. Specific exercises that can be targeted for sprain prevention can be learnt from the physical therapist.
Stretching exercises and muscle training are important in prevention of a sprain. Sprain preventing measures are as follows: 

1. Before beginning an exercise routine, it is essential to do warm up exercises. Slight jogging can be done to activate muscle movement. 

2. Stretching before and after an exercise routine is necessary. It ensures that the muscles around the joint are in a relaxed position. It helps in minimizing the risk of an injury. 

3. Some specific exercises that help to strengthen the muscles around ankles should be done. Heel raise exercise is beneficial in strengthening the ankle muscles. 

4. Exercises that target the improvement of overall body s balance should be done on a regular basis. These exercises help in preventing twisting of ankles during walking or moving down the stairs. 

5. In case of a previous ankle injury, it is recommended to wear an ankle brace to prevent any twisting caused by a dis-balance. 

Treatment of the sprain is done by following the RICE procedure. This procedure includes the protocol of rest, ice, compression and elevation. Analgesics can be taken for pain relief. Ice pack application helps in reducing the swelling. Using a compression bandage helps in immobilizing the injury.

5 Only Exercises For Easy Relief From Knee Pain

Sciatica refers to the pain one experiences due to the irritation or compression of nerve roots contributing to formation of Sciatic nerve. The sciatic nerve is the longest and widest nerve in the body, running from the lower back, down to the back of each leg. The pain can occur in the lower back and spread to the hips, buttocks and leg. Sciatica generally affects one side of the body. There are numerous causes of irritation of the sciatic nerve and sciatica.
 
Some of them are:
 
1. Spinal Stenosis
The narrowing of the spinal canal caused by natural wear and tear of the vertebrae (individual bones in the spine protecting underlying nerves) of the spine is known as spinal stenosis. The narrowing may put pressure on the roots of the sciatic nerve, causing pain.
 
2. Herniated Disc
A disc is made up of cartilage and acts as a cushion between vertebrae, allowing flexibility of the spine. A herniated or slipped disc occurs when a disc is temporarily pushed out of place, putting pressure on the sciatic nerve.
 
3. Spondylolisthesis
It is a condition where one of the lower vertebrae slips forward over another. This also causes a collapse of the disc space between both, causing the nerve to get pinched. This may cause sciatica.
 
4. Piriformis Syndrome
Piriformis is a muscle found deep inside the buttocks, which connects the lower spine to the upper thighbone, running directly over the sciatic nerve. Spasming of this muscle can pressurize the sciatic nerve, triggering symptoms of sciatica.

5. Sacroilitis
Sacroillac joints are the place where the lower spine meets the pelvis and inflammation of one or both of these joints causes sacroilitis. This can give rise to symptoms of sciatica as it causes pain in the lower back, buttocks and legs.
 
6. Spinal tumors
Very rarely, tumors growing inside or along the spine may put pressure on the sciatic nerve.
 
7. Infection or injury
Muscle inflammation, infections, fractures or any other spinal injury may lead to irritation or compression of the sciatic nerve.
 
8. Pregnancy
Pregnant women may suffer from sciatica due to weight gain, expansion of the uterus or increased fluid retention or other changes occurring in the body, which put pressure on the sciatic nerve.
 
9. Other causes
Osteoarthritis and fractures caused by osteoporosis may also affect the sciatic nerve, producing symptoms of sciatica.

Top 9 Causes Of Sciatica Nerve Pain - You Need To Know About

Spondylitis, or cervical spondylitis, is a common condition that affects a large section of the adult population. This most common disorder of the cervical spine is a degenerative condition. There are soft disks between the vertebral bones which shrink with age and gets stiff. This leads to formation of small bone spurs. This reduces the space available for the disk to move, causing nerve pinching.

Causes:

Ageing is the most common cause for spondylitis. Injury, incorrect sleeping posture, and heavy weight-lifting can also cause spondylitis. While earlier it was common in people who were 60-plus, with more people spending more time at their computers and workstations, the onset happens much earlier in 30s and sometimes even in 20s.

Symptoms:

Most symptoms related to spondylitis are centered on the neck and shoulder regions. There is pain and stiffness in the neck that can extend to the shoulders, nape of the neck, arms, and sometimes even the fingers. In rare cases, the pain can extend into the forehead and back of the head too. Associated symptoms include numbness, weakness, and a pricking sensation in the hands, arms, and sometimes fingers.

Homeopathy in cervical spondylitis:

Homeopathy treats the root of the issue after taking into account all symptoms. Listed below are some common homeopathic remedies for spondylitis.

Conium: there is neck pain along with vertigo when lying down or turning in bed. There is constant mild pain in the back of the head and a tight sensation in the forehead region.
Rhus tox: when the neck pain is worse in the morning and with rest, rhus is a good option. Moving the neck helps relieve this pain, which is often as a result of some injury.
Kalmia latifolia: when there is pain extending from the neck to the arm and hand and fingers, kalmia works wonders. There may also be pain from the nape of the neck to the shoulder blades. The pain is increased with leaning forwards or looking down. The patient may also have nausea with the pain.
Gelsemium: when there is pain extending from the neck to the back of the head, centering in the occipital region. The patient also feels weak, dull, and dizzy. The pain is triggered by emotional excitement.
Silicea: when there is pain extending from the neck to the eyes and forehead, silicea provides good relief. The patient will have intolerance to cold and feels chilly. The pain is improved by heat pads and lying down.
Calcarea phos: if the radiographs show bony changes in the cervical spine with the spondylitis, this is very useful. The bony spurs that form can be painful and cause nerve pinching leading to vertigo.
