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

Your spine or backbone is composed of 26 bone discs, known as vertebrae. The vertebra shields your spinal cord and allows you to bend forwards and backwards, and stand. However, a number of problems, such as the following can change the structure or cause the vertebrae and its surrounding tissues to become damaged  

  Injuries
  Infections
  Tumours
  Changes in bone formation due to ageing   herniated disks, spinal stenosis
  Conditions like scoliosis and ankylosing spondylitis

Spinal disorders often lead to pain and discomfort when bony projections put pressure on the spinal nerves or cord. Over time, spinal disorders limit movement and reduce flexibility.
Treatment varies depending on the disease, ranging from medications and therapy to bracing and surgery.

Endoscopic Spine Surgery: what is it?

Contradictory to traditional open surgery, the new age endoscopic surgery is a minimally invasive procedure used to detect and treat a disorder. Unlike open surgery, minimally invasive endoscopic surgery does not require the patient to undergo general anaesthesia. The procedure is possible under local anaesthesia, considering the fact that it can be performed without cutting open the portion of the surgery site.

How does surgery work?

During the procedure, the surgeon first administers local anaesthesia to numb the site of the operation. You will be awake during the entire procedure but will not feel any pain. Then, he/she will make a small incision and insert a slender, tubular instrument   known as an endoscope   with a camera attached on one end through the soft tissues and skin, down to the spinal column. This allows the surgeon to get a clear view of the spinal tissues and understand where the problem exists. The endoscope holds the muscles open, allowing the surgeon to remove the damaged tissues or disk.

Endoscopic spine surgery preserves normal mobility, as the spine is not fused with rods and crews. When performed under an experienced surgeon, the procedure takes less than an hour.

Benefits of the Procedure

The advantages of going for an endoscopic surgery are the following  
  Local anaesthesia
  Surgery and discharge on the same day
  Microscopic incisions
  No removal of bone or muscles
  Zero or minimal blood loss
  Preserves spinal mobility
  Immediate recovery
  Reduced intake of pain medicines
  The high rate of success
  Improved quality of life

Minimally invasive endoscopic surgery has made it possible to rectify spinal problems and disorders without having to go under the knife. With less pain and quicker recovery, you can improve your spine health and get back to your usual activities in a day or two.

Consult a specialist and discuss the procedure in detail before opting for the same.


Endoscopic Spine Surgery Under Local Anaesthesia!

The intervertebral discs are made-up of two concentric layers, the inner gel-like Nucleus Pulposus and the outer fibrous Annulus fibrosus. As a result of advancing age, the nucleus loses fluid, volume and resiliency and the entire disc structure becomes more susceptible to trauma and compression. This condition is called as degeneration of the disc. The disc then is highly vulnerable to tears and as these occur, the inner nucleus pulposus protrudes through the fibrous layer, producing a bulge in the intervertebral disc. This condition is named as herniated disc. This can then cause compression to the spinal cord or the emerging nerve roots and lead to associated problems of Sciatica radiating pain from back to legs in the distribution of the nerve. Other symptoms could be a weakness, tingling or numbness in the areas corresponding to the affected nerve. Sometimes bladder compromise is also present, which is made evident for urine retention and this need to be taken care as an emergency.
Excessive weight, bad postures, undue movements, improper weight lifting and other kinds of traumas may weaken the intervertebral discs. When this occurs the pulpous nucleus will bulge against the annulus, or even be squeezed through it (extruded disc).

The first steps to deal with a herniated or prolapsed lumbar disc are conservative. These include rest, analgesic and anti-inflammatory medication and in some cases physical therapy. At this point, it is convenient to have some plain X-rays done, in search of some indirect evidence of the disc problem, as well as of degenerative changes on the spine.

If in a few days these measures have failed, the diagnosis has to be confirmed by means of examinations that give better detail over the troubled area, as the MRI, CT which will show the disc, the space behind it and in the first case, the nerves. In some instances, the EMG (electromyography) is also of great value, as this will show the functionality of the nerves and muscles.

Once the diagnosis has been confirmed, one of the best alternatives existing today is the Ozone Discolysis as the results obtained are excellent and practically has no complications. This novel treatment avoids the use of surgery in 80% of those who needed it. In most patients left with painkillers as the only treatment, the symptoms eventually disappear, only that this could take weeks to months. Ozone speeds up these developments, see the same result in a few weeks. The problem has to be seen and approached integrally and frequently the combination of therapies has to be used, most frequently physiotherapy. Also, it has to be known that those who had a herniated disc have 10 times more chances of having another herniation than the rest of the population.

If despite the ozone therapy the symptoms persist, Drill Discectomy/ Laser Discectomy are good alternatives before open surgery (Discectomy) which has to be contemplated in those true emergencies, as mentioned above, this is possibly the first choice.

Once the conservative treatment fails:

Early aggressive treatment plan of pain has to be implemented to prevent peripherally induced CNS changes that may intensify or prolong pain making it a complex pain syndrome. Only 5% of total LBP patients would need surgery & 20% of discal rupture or herniation would need surgery. Nonoperative treatment is sufficient in most of the patients, although patient selection is important even then.

Depending upon the diagnosis one can perform & combine properly selected percutaneous fluoroscopic guided procedures with time spacing depending upon pt`s pathology & response to treatment.

Using precision diagnostic & therapeutic blocks in chronic LBP, isolated facet joint pain in 40%, discogenic pain in 25% (95% in L4-5&L5S1), segmental dural or nerve root pain in 14% & sacroiliac joint pain in 15% of the patients. This article describes successful interventions of these common causes of LBP after conservative treatment has failed.

LESI: Lumbar Epidural Steroid Injection

Indicated in   Acute radicular pain due to irritation or inflammation.

Symptomatic herniated disc with failed conservative therapy
Acute exacerbation of discogenic pain or pain of spinal stenosis
Neoplastic infiltration of roots
Epidural fibrosis
Chronic LBP with acute radicular symptoms
Epidural- lumbar injection
ESI Treatment Plan

Compared to interlaminar approach better results are found with a transforaminal approach where drugs (steroid+ LA/saline +/- hyalase) are injected into anterior epidural space & neural foramen area where herniated disc or offending nociceptors are located. Whereas in interlaminar approach most of drug is deposited in posterior epidural space.Drugs are injected total 6-10 ml at lumbar, 3-6 ml at cervical & 20+ ml, if caudal approach is selected. Lumbar ESI is performed close to the level of radiculopathy, often using paramedian approach to target the lateral aspect of the epidural space on involved side. Cervical epidural is performed at C7-T1 level.

SNRB- Selective Nerve Root Block 

Fluoroscopically performed it is a good diagnostic & therapeutic procedure for radiculopathy pain if

There is minimal or no radiological finding.
Multilevel imaging abnormalities
Equivocal neurological examination finding or discrepancy between clinical & radiological signs
Postop patient with unexplainable or recurrent pain
Combined canal & lateral recess stenosis.
To find out the pathological dermatome for more invasive procedures, if needed
Intradiscal Procedures 

Provocative Discography - Coupled with CT

A diagnostic procedure & prognostic indicator for surgical outcome is necessary for the evaluation of patients with suspected discogenic pain, its ability to reproduce pain(even with normal radiological finding), to determine type of disc herniation /tear, finding surgical options & in assessing previously operated spines.

Percutaneous Disc Decompression (PDD)

After diagnosing the level of painful offending disc various percutaneous intradiscal procedures can be employed

Ozone Discolysis: Ozone Discectomy a revolutionary least invasive safe & effective alternative to spine surgery is the treatment of choice for prolapsed disc (PIVD) done under local anaesthesia in a daycare setting. This procedure is ideally suited for cervical & lumbar disc herniation with radiculopathy. The total cost of the procedure is much less than that of surgical discectomy. All these facts have made this procedure very popular at European countries. It is also gaining popularity in our country due to high success rate, less invasiveness, fewer chances of recurrences, remarkably fewer side effects meaning high safety profile, short hospital stay, no postoperative discomfort or morbidity and low cost.

Dekompressor: A mechanical percutaneous nucleosome cuts & drills out the disc material somewhat like morcirator debulking the disc reducing nerve compression.

Epidural Adhenolysis or Percutaneous Decompressive Neuroplasty for Epidural Fibrosis or Adhesions in Failed Back Surgery Syndrome (FBSS)

A catheter is inserted in epidural space via caudal/ interlaminar/ transforaminal approach. After epidurography testing volumetric irrigation with normal saline/ L.A./ hyalase/ steroids/ hypertonic saline in different combinations is then performed along with mechanical adenolysis with spring loaded or stellated catheters or under direct vision with epiduroscope.

Procedures That Can Help Treat Slip Disc & Sciatica!

There are many changes that take place in our face and body as we start ageing. While the face starts to show the signs of ageing earliest-in the form of wrinkles and fine lines as well as a sagging chin and neck, the effect of ageing on the body might be slightly late. The skin may sag or you may end up putting on weight in various parts of the body like upper arms, which may look unsightly and bring down your level of confidence as well. Signs of ageing can often make you shy away from living your life to the fullest. 

For the sagging upper arms, one can always get a procedure called an Arm lift. This is also called a Brachioplasty. This is a cosmetic procedure that can be conducted to tighten the skin of the arms from the elbow upwards. Let s see how this procedure works.

What does it do?

Excess fat tends to accumulate in both arms togather with weight gain. Person face laxity in this area after massive weight loss or with body ageing.
Arm Lift is a surgical procedure to tighten the skin in the arms through the removal of excess fat deposits as well as skin.
Who can opt for this surgery?

Any person who is medically fit having arm disfigurement can opt for this procedure. Patients who have signs of ageing or excessive weight gain are the best candidates for this kind of surgery. Also, it may be used by the patients who are suffering from sagging skin after losing a great deal of weight which may lead to an appearance of bat s wings on the sides.

How is this procedure conducted?

This surgical procedure is conducted by a Cosmetic Plastic Surgeon. It s a day-care procedure. The doctor begins by marking the various areas of concern having excess fat and flabby skin. Thereafter, the doctor proceeds to remove the excess skin so that the arms are tightened getting more youthful look. This is done under anaesthesia to make patient pain-free. The skin that is removed is usually shaped like an ellipse. In many cases, there may be a need to conduct a liposuction if the patient has excess fat as well. Once the excess skin has been removed, skin edges are approximated with meticulous sutures with various Plastic Surgery techniques.

Recovery usually takes 5-7 days. Person can resume routine activities from very next day. Sometimes you might be advised a pressure garment for better outcome.

Upper Arm Lift - What It Can Do?

Wounds and bruises are both injuries. However, they differ widely in terms of the causing factors, the nature of the injury, the pain they cause and the kind of treatment they require. The following are a few of the myriad ways in which the two injuries differ from each other:

1. A wound causes quick damage - the skin tissue is cut or punctured while a bruise (also called a closed wound) is where the skin is not torn. 

2. A wound is usually caused by a sharp object but bruises are the results of blunt force or trauma.

3. A wound almost certainly bleeds due to ruptured tissue and blood vessels. Blunt injury also damages the blood capillaries of the skin and causes blood to accumulate under the skin tissue, creating a dark patch of skin. Blood vessels can also break due to lifting of heavy objects or overexertion of muscles.

4. A wound carries the risk of infection because the skin is open but a bruise does not get infected.

5. A wound has a burning or stinging sensation but a bruise is characterized by swelling and a blunt throbbing pain.

6. A wound can be healed by antiseptic and antibiotic medication. Large wounds need to be closed by stitching them up to avoid severe infection. On the other hand, a bruise usually heals by itself. A cold compress and pain killers may be used to ease discomfort. Heat can be applied to the injured spot to normalize the blood flow and dissolve the blood clot.

7. A wound can lead to complications like bacterial infections or the healing might be delayed by chronic diseases like diabetes. In case of a bruise, it usually does not cause complications but if there's a blunt injury to sensitive areas like the head, the tailbone or the eyes, medical attention is advised.

8. Wounds and bruises can also be differentiated on the basis of their subtypes. The different types of wounds are:

a. Incision (sharp objects cutting the dermis layer of skin)
b. Abrasion (the epithelial tissue is scraped off)
c. Avulsion (a body structure is torn off)
d. Penetration (a sharp object causes an entry and an exit wound)
e. Puncture (only an entry wound caused by a sharp object)

The different types of bruises are:
a. Hematoma (blood pools under the skin)
b. Purpura (tiny spots of blood on the inside of the mouth)
c. Contusion (similar to hematoma and caused by external trauma)
d. Crush injury (caused due to a large amount of force on the body part for a long time)

Wounds VS Bruises

Foot pain contributes around 3-5 % of patients visiting Orthopedic OPD, with heel pain being predominant complaint. Heel pain commonly involves the underside or back of your heel. Although not a symptom of a serious condition, it s disabling as it can interfere with your routine activities.

Plantar fasciitis, Achilles tendinitis, Heel spur, Retrocalcaneal bursitis are few common conditions causing heel pain.

The below few conditions which are prone to developing heel pain like:

Abnormal walking style (gait)/altered alignment of the foot
Obesity
Ill-fitting shoes/ badly-worn shoes
Standing, running or jumping on hard surfaces
Injury to the heel, such as stress fractures
diabetes and arthritis
The most common causes of heel pain are plantar fasciitis (bottom of the heel) and Achilles tendinitis (back of the heel).

Presenting complaints:

Pain which is usually intense in the mornings or after a long period of res,
Discomfort or swelling in the back of your heel
Skin on your heel overly warm to the touch
