Dr. Ebraheim’s educational animated video describes avascular necrosis and osteonecrosis. Avascular necrosis or osteonecrosis is death of a segment of bone due to loss of blood supply. Both bone cells and the bone marrow are affected. AVN I a common cause of hip pain in young and middle aged patients between 35-50 years of age. It occurs more in males. AVN leads to severe degenerative arthritis of the hip joint and accounts for 10% of total hip replacement cases in the United States. The femoral head the most common site of atraumatic AVN. The humeral head is the second most common area. Bilateral AVN occurs in 80% of cases and each side may present a different stage. Check the other hip x-rays even if asymptomatic. The exact etiology and process of AVN is not known. Interruption of the blood supply of the femoral head is a common pathway. Genetic factors may also be implicated as the cause of AVN. Early diagnosis detects early stages of AVN that can be helped by a head preserving procedure such as decompression, bone graft or vascularized fibular graft. With multifocal osteonecrosis, three or more sites occur in about 3% of patients. It can affect the hip, knee, shoulder or ankle. Patients with osteonecrosis at a different site than the hip should undergo an MRI of the hip to rule out asymptomatic osteonecrosis of the hip. X-rays are initially normal. MRI is the best study when the x-ray is normal and AVN is considered or suspected. The AVN is seen on the anterosuperior aspect of the femoral head. Trauma such as hip fracture or dislocation can cause AVN. The most common causes of AVN are steroid use, alcohol, gout, metabolic and genetic problems. The condition may be associated with a hypercoagulability state such as decrease in protein S, protein C, and factor V Leiden (We routinely get that study with AVN cases). The condition may also be idiopathic (without a cause), the AVN is a diagnosis of exclusion. If the Frog lateral view shows a crescent sign, it means that osteonecrosis is present and probably advanced. Double density on MRI is pathognomonic for AVN. The patient may be asymptomatic and may present with dull hip pain (anterior groin pain) or severe arthritis pain due to collapse of the joint. With early arthritis, the patient will have a decrease in internal rotation of the hip. On the x-ray, the patient will have a flattened contour with collapse of the femoral head and decreased joint space. If the joint surface is intact, without collapse, core decompression or vascularized bone graft is helpful. If the joint is collapsed, arthroplasty is the procedure of choice and rarely an osteotomy is done. Bisphosphonates are used in early stages of AVN. It prevents femoral head collapse, however, the results are controversial. Rule out other causes of hip pain such as gout, PVNS, femoral inguinal hernia, rheumatoid arthritis or stress fracture of the femoral neck.

Dr. Ebraheim’s educational animated video describes the condition of avascular necrosis. Avascular necrosis or osteonecrosis is the death of a segment of bone due to disruption of the blood supply. Causes of avascular necrosis are numerous. There are different ways that could interrupt the blood supply. 1-Trauma: avascular necrosis may occur due to trauma as described in the previous video. These are examples of how trauma associated with dislocation or fracture of the femoral neck may interrupt the blood supply of the hip. Hip dislocation, femoral neck fracture due to mechanical disruption of the blood vessels. 2-Occlusion of the arterial blood supply: avascular necrosis may occur due to occlusion of the arterial blood supply by fat embolism, nitrogen bubbles in the blood stream (Caisson disease) or with sickle cell disease. Avascular necrosis may also occur due to fat embolism. To explain sickle cell anemia, under low oxygen levels, the cells become sickle shaped and unable to pass through the vessels. Results in diminished blood flow leading to AVN. Patient with sickle cell disease and asymptomatic AVN diagnosed by MRI will have a higher incidence of progression to collapse of the AVN and pain (75%). Deterioration of the AVN will be rapid and can be bilateral. Screen the other hip now and periodically. Also, watch the humeral head for AVN. 3-Obstruction of the venous outflow: leads to increased interosseous pressure. 4-Injury or pressure on the blood vessel wall: Gaucher's disease: increased fat cell size may prevent the arterial inflow and lead to ischemia. Marrow disease such as lymphoma and leukemia may also cause AVN. Radiation, vasculitis, and cytotoxins. 5-AVN may be associated with hypercoagulable states such as decreased anticoagulants, protein S and protein C. increased procoagulants. Most common causes: •Trauma •Steroid use •Alcohol •Idiopathic (no cause) •Metabolic and genetic factors •Systemic lupus erythematosus (SLE) •Renal failure •Organ transplant •Hemophilia All of these conditions may cause loss of the vascular supply, marrow necrosis, and osteocyte death. Important conditions related to AVN: Steroid use: high doses for 2-3 weeks or low doses for long durations can cause AVN. There is a direct connection between the dose and duration of steroid use in the development of AVN. Joint injection is not proven to cause AVN. HIV: avascular necrosis of the femoral head is a complication in HIV infected patients. The increased incidence of AVN may be caused by an increased prevalence of predisposing factors of osteonecrosis, including protease inhibitors, hyperlipidemia, corticosteroid use, alcohol and intravenous drug use. Protease inhibitors play a role in the development of osteonecrosis through a tendency to cause hyperlipidemia. Causes of AVN mnemonic A S E P T I C •ALCOHOLISM/ AIDS •SICKLE CELL DISEASE/ SLE •ERLENMYER FLASK (Gaucher’s) •PANCREATITIS/PREGNANCY •TRAUMA •IDIOPATHIC/INFECTION •CAISSON’S (the bends) AVN is death of a segment of bone. The anterosuperior segment of the femoral head is the area usually affected. Resorption of some of the dead bone is bone by osteoclasts. Dead trabecular bone is resorbed, ready to be remodeled. Osteoclasts resorb some of the dead bone. Osteoblasts lay down new woven bone. The process is repeated and the bone becomes weak. At this weakest stage the AVN will result in collapse. Remodeling is not enough to support the bone. Progressive collapse due to bone death, resorption, remodeling, and microfracture. AVN ends by final collapse, joint changes, and arthritis.

Dr. Ebraheim’s educational animated video describes avascular necrosis, and the of the femoral head, the signs, symptoms, diagnostic tests, prognosis. Avascular necrosis or osteonecrosis is death of a segment of bone due to disruption of the blood supply. Extraosseous or intraosseous interruption of the venous or arterial blood flow. Mechanism of injury: fractures of the femoral neck or dislocation of the hip, mechanical disruption of the blood vessels. Trauma to the deep branch of the medial femoral circumflex artery may occur with antegrade rod placement during piriformis entry in children. Posterior dislocation of the femoral head should be reduced in an expedited way to decrease the risk of thrombosis of the vessels which supply the femoral head. Osteonecrosis develops in about 2-20% of hips that are reduced within 6 hours. The risk of osteonecrosis will increase with delay in reduction of the hip. Osteonecrosis appears within two years after the injury. It is evident within one year in most patients. Pipken fracture: the patient should be informed about the complications of AVN preoperatively. Fixation failure is associated with osteonecrosis or nonunion. The affect of the anterior approach on osteonecrosis is not known. Stress fracture should be pinned before displacement occurs. Displacement will have a bad result. Acute femoral neck fracture: nondisplaced 15% AVN, displaced and fixed properly 20-30%. Osteonecrosis can be clinically significant when followed by lateral segmental collapse. The more vertical the fracture, the more chance that AVN will occur. Intraoperative dissection: in acetabular fracture fixation, during intraoperative dissection for acetabular fracture reduction and fixation, avoid injury to the ascending branch of the Medial Femoral Circumflex Artery (MFCA). Fractures of the hip in children are associated with a high rate of osteonecrosis. Four types can be identified according to Delbet classification: Type I: Transphyseal injury 90-100% AVN. Type II: Transcervical 50% AVN. Type III: Cervico-trochanteric (or basicervical) 25% AVN. Type IV: Intertrochanteric 10% AVN.

Educational video describing the conditions affecting the blood supply of the femoral head. Where is the important blood supply of the femoral neck located? On the postero-superior aspect of the femoral neck. The main blood supply for the weight-bearing dome of the femoral head is the medial femoral circumflex artery (lateral epiphyseal artery). Using an awl at the piriformis fossa in children requiring intramedullary fixation of their femur fracture may endanger the blood supply and cause avascular necrosis of the femoral neck. Avascular necrosis is death of a segment of bone. High energy neck fracture •Vertical fracture of the femoral neck that has vertical obliquity of 70 or more degrees. Has a high rate of nonunion and avascular necrosis. •Displacement of the femoral neck fracture disrupts the blood supply (kinks the retinacualr vessels). Pressure from the intracapsular hematoma may affect the blood supply. Clinical picture •Hip is in flexion and external rotation •Surgical emergency in young adults to unkink the vessels. Treatment •Obtain anatomic reduction in young adults. •Open reduction if closed reduction is not possible, use Watson Jones approach between the gluteus medius and the tensor fascia latae. •Follow the patient with an MRI to evaluate AVN. •If the patient develops nonunion and the head is viable, treat the nonunion by valgus intertrochanteric osteotomy. Hip dislocations Posterior dislocation is common. Anterior dislocation is rare. Treatment Emergent closed reduction within 6 hours. Assess hip stability post-reduction. Other factors associated with hip osteonecrosis •Corticosteroid use •Alcohol abuse •Hemoglobinopathy •Coagulopathy •Gaucher disease •Pregnancy (rare). Idiopathic AVN Nontraumatic AVN of the femoral head is located anterolateral. Become a friend on facebook: 🤍 Follow me on twitter: 🤍

Osteonecrosis also called avascular necrosis, or bone infarction is a condition that results from an interruption of blood supply to the bone. • The bone is a living tissue that requires blood, a lack of blood flow to the bone can lead to the death of bone tissue. If not treated, it can eventually cause the bone to collapse. • The condition also causes the bone to lose its smooth shape, leading to severe arthritis. • The most commonly affected joint is the hip bone but other common sites are the knees, shoulder, and ankles. • Estimate has shown that as many as 20,000 people develop the condition annually. • Anyone can be affected, but osteonecrosis is most prevalent in people between the ages of 20 and 50.

Dr. Ebraheim’s educational animated video describes osteonecrosis of the femoral head - Hip. Follow me on twitter: 🤍 Osteonecrosis of the Hip Osteonecrosis or avascular necrosis of the hip means death of a segment of the bone in the femoral head due to interruption of the blood supply. The etiology of this condition is not fully understood. There are several risk factors associated with osteonecrosis of the hip. Direct risk factors for osteonecrosis include trauma, radiation, and hematologic disorders such as lymphoma, leukemia, cytotoxins, Gaucher disease, Caisson disease, and Sickle Cell disease. Indirect risk factors for osteonecrosis include steroid use, alcohol abuse, renal failure, organ transplant, systemic lupus erythematosus (SLE), idiopathic osteonecrosis, hemophilia, and thrombophilia. Osteonecrosis may be bilateral in about 80% of the patients. Check the other hip even if it is asymptomatic. Early diagnosis and treatment may improve the chances for success of a head preserving surgical procedure, such as core decompression or bone grafting. In late stages of osteonecrosis, the femoral head collapses and cannot be saved. For the patient to have a good outcome, the femoral head will need to be replaced at this late stage. Obtain AP and frog leg lateral views of the hip. The frog leg lateral view will show the crescent sign. MRI is the study of choice, especially when the patient has persistent hip pain and the radiographs are negative and the diagnosis of osteonecrosis of the femoral head is suspected, especially if the patient has risk factors. On the T1 MRI, there is a well-defined band of low signal intensity usually within the superior anterior portion of the femoral head. Decreased signal from the ischemic marrow and there is a single band-like area of low signal intensity (crescent sign). The crescent sign represents the reactive interface between the necrotic and reparative zone. The single line density demarcates the normal from the ischemic bone. Double Line Sign is seen in T2 images. The subchondral lesion on T2 shows two lines the low signal intensity line and the high signal intensity line. The lesion will show a high signal intensity inner border with a low signal intensity peripheral rim (double line). The high signal intensity represents hyper vascular granulation tissue. The size of the lesion is the most important factor in determining the development of symptoms and the progression of the disease. The best prognosis occurs in a small lesion with sclerotic margins. The presence of bone marrow edema on the MRI is predictive of worsening of the pain and future progression of the disease. Multifocal osteonecrosis, which is disease involving three or more sites such as the hip, the knee, the shoulder, and the ankle, occurs in about 3% of patients. A patient that presents with osteonecrosis at a site other than the hip should undergo MRI of the hip to rule out the asymptomatic lesion in the femoral head. Transient osteoporosis of the femoral head is not osteonecrosis of the femoral head. In transient osteoporosis, the symptoms are usually more than the x-ray findings. Transient osteoporosis affects pregnant women, and it affects men during the 5th decade of life. On x-ray, you probably will not find much (may find osteopenia). The MRI is probably characteristic (you will find bony edema and increased signal intensity in T2 MRI). The signal changes will involve the femoral head and extend into the neck, and may be even the intertrochanteric area. With transient osteoporosis, there is no double density which is on MRI with osteonecrosis. Transient osteoporosis is not a tumor, it is not osteonecrosis and it does not need surgery. The Ficat classification is a commonly used system to stage osteonecrosis of the hip. Stage I has a normal x-ray; MRI has abnormal signal (changes in the marrow), and the bone scan will show increased uptake. In Stage II, the x-rays will show mixed osteopenia and/or sclerosis. There might be subchondral cysts and lucencies. There is no crescent sign, no subchondral fracture, and no collapse. The MRI and bone scan will be abnormal. In Stage III, the x-ray will show the crescent sign, which is a subchondral fracture line and may be associated with collapse of the femoral head. MRI will show the changes that are seen in the x-rays. In Stage IV, the x-ray will show collapse of the subchondral bone and severe deformity of the head with secondary degenerative changes affecting both sides of the joint.

Avascular necrosis, or osteonecrosis, of the hip refers to the progressive death of the bone under the articular cartilage of a joint, most commonly the femoral head of the hip. It usually results from the loss of the blood supply to the bone in this region. It can occur after a traumatic event, such as a hip dislocation or subluxation, but it can result from alcohol use, steroids, and medical issues. In the hip, it often presents as groin pain. Severity can range from mild pain and no articular cartilage breakdown to collapse of the bone and cartilage with degeneration of the involved joint. 🤍 I want to help you!

CAUSES OF AVASCULAR NECROSIS OF THE HIP Avascular necrosis can often develop after a traumatic injury that disrupts the blood vessels supplying the femoral head. A displaced femoral neck fracture or a hip dislocation can lead to later AVN. This condition can also occur without a traumatic event. Some of the risk factors associated with osteonecrosis include long-term use of steroid medications, chronic alcohol use, and many medical conditions, such as sickle cell disease. SIGNS AND SYMPTOMS OF OSTEONECROSIS A patient with avascular necrosis will often notice hip and groin pain. Certain motions and walking can make this pain worse. Over time as the condition worsens, the patient might lose range of motion in the affected hip. DIAGNOSIS OF AVASCULAR NECROSIS An orthopedic surgeon will check the patient’s hip range of motion and look for other areas of tenderness. X-rays of the hips can demonstrate the collapse of the femoral head, if it’s present. An MRI can be useful, especially in the early stages of the condition, when x-ray changes are not as noticeable. An MRI might also show changes in the opposite femoral head, even before a patient starts having pain on that side. TREATMENT OPTIONS Generally nonsurgical treatments for avascular necrosis can decrease pain, but they do little to slow the progression of the disease process. Using crutches to decrease weight on the hip can lessen pain. OPTIONS FOR SURGERY Surgery to try to restore blood supply and preserve the femoral head can be a reasonable option, especially in the earlier stages of this condition. One option for some patients involves core decompression, where the surgeon drills holes in the femoral neck to decrease pressure and increase blood flow to the femoral head. Another option is to add bone graft to the drill holes to try to support the bone of the femoral head. Transferring a part of the fibula (long bone on the outside of the leg) with its blood supply to the femoral neck and head can be an option as well.

Dr. Ebraheim’s educational animated video describes avascular necrosis of the shoulder and proximal humerus. Avascular necrosis is the death of a segment of bone. AVN may affect the proximal humerus due to interruption of the blood supply. The ascending branch of the anterior humeral circumflex artery runs in the lateral bicipital groove and then becomes the arcuate artery. The other artery that is important to the blood supply is the posterior humeral circumflex artery. Causes of AVN: •Alcohol •AIDS •Sickle cell disease •Systemic lupus erythematosus (SLE) •Idiopathic •Infection •Trauma •Gaucher’s disease •Steroid use: incidence of AVN is between 5-25% after systemic steroid use. Steroids increase serum lipids in the blood. It may precipitate fat embolism into the humeral head blood vessels. Post trauma: Anterior or posterior dislocation of the humeral head is not associated with AVN. The incidence of AVN: •100% four part fracture dislocation. •50% displaced four part fracture. •15% three part fracture. •10% valgus impact fracture. Classification of proximal humeral AVN •Stage I:normal X-ray •Stage II: sclerosis •Stage III: crescent sign •Stage IV: flattening and collapse •Stage V: degenerative arthritis. Progressive collapse of the humeral head occurs due to bone death, resorption, remodeling, microfractures and final collapse with joint changes and arthritis. Symptoms: •Shoulder pain •Weakness •Crepitus •Decreased range of motion Symptoms are gradual and insidious with delay in the diagnosis and treatment. The patient usually has a history of risk factors. x-rays: shown best in neutral rotation AP view. AVN located on the superior middle part of the humeral head just deep to the articular cartilage. Crescent sign =collapse. MRI is the best study. Patient with AVN of the humerus should have a hip radiograph. If X-ray is negative and the patient has hip pain, obtain an MRI of the hip. It is recommended that a patient with osteonecrosis at the site of the shoulder should undergo an MRI of the hip to rule out asymptomatic osteonecrosis of the hip. You may also need to do an X-ray of the knee. AVN may involve three or more anatomic sites (multifocal osteonecrosis). Treatment •Physical therapy •NSAIDS •Core decompression for stage I & stage II •Resurfacing for stage III •Hemiarthroplasty for stage III & stage IV •Total shoulder surgery for stage V: advanced disease, the results of the total shoulder are inferior to a patient with osteoarthritis.

An introduction of Avascular Necrosis with symptoms, causes and various treatments of AVN hip explained by Dr. Gaurav Khera & Clinic Avascular necrosis is the death of bone tissues due to a lack of blood supply. AVN is also known as Osteonecrosis, it can lead to tiny breaks in the bone and the bone's eventual collapse due to body weight. Avascular necrosis is also associated with long-term use of high-dose steroids, alcohol and excessive painkillers. AVN can affect anyone but the condition is most common in people between the age of 35 to 50.

🤍 Transcript Hello, Dr. Markle at Centeno-Schultz Clinic. Today, we’re talking about Avascular Necrosis in the shoulder. Now a recap: Avascular Necrosis is essentially a lack of blood flow, eventually resulting in necrosis, or dying of the bone. This happens in multiple joints. And today we’re talking specifically about the shoulder. So talking about AVN in the shoulder, patients typically come up with two main questions. Number one, can this heal on its own? And if not, how long or how fast will this progress? avascular necrosis in the shoulder - progression Now we classify AVN in multiple different stages: Number one: we have stage one, where it’s very normal X-ray — usually, typically, someone just has pain with activity. Two: is the bone itself continues to deteriorate, then we start getting some changes on your X-ray. Number three: as that lack of blood flow to the bone progresses, we’re getting what we call a crescent-shaped lesion in the bone. And we start changing some of the architecture of the joint. Stage four and stage five is when we start losing full architecture, where we have collapse or flattening of the joint’s surface. That flattening of the joint’s surface essentially leads to severe degeneration or secondary arthritis of the joint. How Fast Is this Progress? For each individual it can be extremely different. It could progress over a number of months — could progress over a number of years. Typically, at the time of diagnosis, if someone is symptomatic, the chances of progressing over a three year period is probably in the 85/90 percent range. If someone is asymptomatic, meaning this was found just by chance, or for a different reason, someone has a chance progression of probably 65 percent. And that progression looks like this. Where, initially, you have some mild changes on the X-ray. Typically, the symptoms are very mild. As we progress, here is that crescent shape lesion. And, on the bottom right, total destruction of the joint. Is AVN of the Shoulder Serious? In one word: yes. It’s extremely serious from the perspective of joint preservation. Now, the earlier we are able to identify this, the quicker we’re able to identify some of the causes of the AVN, remove those causes, and, hopefully, stop the progression. And if we treat this early enough, the goal is joint preservation, so we can avoid the need for a total of joint replacement. What Is the Best Treatment for Avascular Necrosis of the Shoulder? If we look at the last 15 to 20 years from a research standpoint, there’s been two main treatments that become more standard of care. One is the removal of whatever is causing Avascular Necrosis, such as if it is high-dose cortical steroids; stop the steroid use. Or, if someone’s consuming high amounts of alcohol. Ideally, abstaining from alcohol use itself will, ideally, help stop the progression. From a treatment standpoint, trying to get the Avascular Necrosis to reverse or cure. That’s why identifying early-on and getting in that early stage one to stage three is extremely important. For an orthopedic surgeon, they typically do what’s called a core decompression, where they take a large drill bit, go into the bone itself and ideally try to stimulate the bone, to regenerate it. Aside from that, a less invasive option would be a bone marrow concentrate, utilizing the repair cells in your bone marrow — concentrating them, and, with a small needle, injecting them directly into the lesion to stimulate your body to regenerate the blood flow, as well as try to heal the bone itself. Best treatment for Avascular Necrosis in the Shoulder Here’s a nice progression from someone that was diagnosed from a stage three (see above). All this area is Avascular Necrotic lesions. We can see the crescent-shape lesion here (where it says “Pre-treatment,” to the left). But the good news is they still had preservation of the joint structure. After treatment, we can see five months (middle). We have a resolution of the majority of the bone swelling. We still have a small lesion, but it hasn’t progressed, and, if we fast forward several years, the patient themselves is 95 percent improved from pain and function after two years. And there’s been no progression of the Avascular Necrosis lesion, as well as the joint preservation aspects are maintained (the right-most image). So, if you or any loved one have been dealing with any issues with Avascular Necrosis in the shoulder, feel free to give us a call. If you have any questions, you can always reach out to us on social media, such as Instagram, Facebook, and we’re always more than welcome to do Telemedicine evaluations. You can send in your imaging and set up a review of your imaging to see if you are a candidate for these advanced regenerative techniques. Have a good day.
Dr Himanshu Tyagi, Senior consultant Spine & orthopedic surgeon. Ph : 9654095717 MCh Orthopaedics (U.K), FNB Spine surgery, DNB Orthopaedics Avascular necrosis is the death of bone tissue due to a lack of blood supply. Also called osteonecrosis, it can lead to tiny breaks in the bone and the bone's eventual collapse. A broken bone or dislocated joint can interrupt the blood flow to a section of bone. Avascular necrosis is also associated with long-term use of high-dose steroid medications and excessive alcohol intake. Anyone can be affected, but the condition is most common in people between the ages of 30 and 50. Symptoms Many people have no symptoms in the early stages of avascular necrosis. As the condition worsens, your affected joint might hurt only when you put weight on it. Eventually, you might feel the pain even when you're lying down. Pain can be mild or severe and usually develops gradually. Pain associated with avascular necrosis of the hip might center on the groin, thigh or buttock. Besides the hip, the areas likely to be affected are the shoulder, knee, hand and foot. Some people develop avascular necrosis on both sides (bilaterally) — such as in both hips or in both knees. Causes Avascular necrosis occurs when blood flow to a bone is interrupted or reduced. Reduced blood supply can be caused by: Joint or bone trauma. An injury, such as a dislocated joint, might damage nearby blood vessels. Cancer treatments involving radiation also can weaken bone and harm blood vessels. Fatty deposits in blood vessels. The fat (lipids) can block small blood vessels, reducing the blood flow that feeds bones. Certain diseases. Medical conditions, such as sickle cell anemia and Gaucher's disease, also can cause diminished blood flow to bone. For about 25 percent of people with avascular necrosis, the cause of interrupted blood flow is unknown. Risk factors Risk factors for developing avascular necrosis include: Trauma. Injuries, such as hip dislocation or fracture, can damage nearby blood vessels and reduce blood flow to bones. Steroid use. Use of high-dose corticosteroids, such as prednisone, is a common cause of avascular necrosis. The reason is unknown, but one hypothesis is that corticosteroids can increase lipid levels in your blood, reducing blood flow. Excessive alcohol use. Consuming several alcoholic drinks a day for several years also can cause fatty deposits to form in your blood vessels. Bisphosphonate use. Long-term use of medications to increase bone density might contribute to developing osteonecrosis of the jaw. This rare complication has occurred in some people treated with high doses of these medications for cancers, such as multiple myeloma and metastatic breast cancer. Certain medical treatments. Radiation therapy for cancer can weaken bone. Organ transplantation, especially kidney transplant, also is associated with avascular necrosis. Medical conditions associated with avascular necrosis include: Pancreatitis Diabetes Gaucher's disease HIV/AIDS Systemic lupus erythematosus Sickle cell anemia Complications Untreated, avascular necrosis worsens with time. Eventually, the bone can collapse. Avascular necrosis also causes bone to lose its smooth shape, potentially leading to severe arthritis. Prevention To reduce your risk of avascular necrosis and improve your general health: Limit alcohol. Heavy drinking is one of the top risk factors for developing avascular necrosis. Keep cholesterol levels low. Tiny bits of fat are the most common substance blocking blood supply to bones. Monitor steroid use. Make sure your doctor knows about your past or present use of high-dose steroids. Steroid-related bone damage appears to worsen with repeated courses of high-do se steroids. Don't smoke. Smoking increases the risk. #spine #backpain #spinehealth #spinesurgeon #slipdisc #drhimanshutyagi #bestspinesurgeon #scoliosis #scoliosistreatment #scoliosissurgery #kneepain #kneereplacement #kneesurgeon #kneearthritis #knee #kneepainhomeremedies #neckpain #neckpaintreatment #neck #cervicaldischerniation #cervicalpain #cervicalspondylosis #cervicalspine #cervical_spondylosis #lumbar #lumbarfusion #lumbarpain #lumbarspondylosis #lumbarspine #surgery #surgeryresults #surgery #hipreplacement #hipreplacementsurgery #hipsurgery #avascularnecrosis #avascular #avascularnecrosistreatment

Thomas Youm, MD (New York, NY) discusses the etiology and indications for treatment of avascular necrosis (AVN) of the hip.
Avascular necrosis of the hip: how common is it and when it does occur is there a common reason? Avascular necrosis of the hip or femoral head is not all that rare. Avascular necrosis refers to a process where the bone undergoes cell death due to a lack of bloodflow. There are a few different theories as to how that actually occurs, but there’s no definite mechanism established for it. Probably the most common causes for avascular necrosis of the hip would be “idiopathic”. This is a fancy way for saying, “we don’t know why it happens”. Second, probably at some point in time there was the use of oral steroids. These are steroids taken for a medical reason. These have been linked to the development of osteonecrosis or avascular necrosis. Another predicting factor is a history of excessive alcohol use. Avascular necrosis of the hip or avascular necrosis of the femoral head has also been linked to some blood clotting disorders, viruses like HIV and medications used to treat HIV..

AVN ( Avascular necrosis) is one of the commonest causes for hip pain in young people it is caused by lack of blood supply in head of femur. Many young people take serioed regularly for various reasons:- 1. Allergy 2.chest problems 3. Skin disease 4. Auto immune disease 5. Body building 6. Sports Steroids cause blockage of small blood vessels carrying blood to head of femur. These patients present with pain, limp , shortening of limb and difficulty in various daily activities. Dr. Ashwani Maichand at new Delhi has changed the scenario of hip replacement by MIS technique . The only reliable treatment for AVN is hip replacement. for appointments:- +919999074745 For mor information log on to : Drashwanimaichand.com
"For probably half of the patients who have it, we don't have a specific cause." Doctor Thomas P. Sculco, Surgeon-in-Chief at the Hospital for Special Surgery in New York, notes the many causes of avascular necrosis what also admits that they still have much to learn about the causes.
