Experiencing Groin Pain or Difficulty Sitting Cross-Legged?
Suspect 'Avascular Necrosis of the Femoral Head.'

1. Avascular Necrosis of the Femoral Head.
Avascular Necrosis of the Femoral Head is a progressive disease that presents differently from fractures.
The nature of the condition can be understood directly from its name:
-Femoral Head: The uppermost part of the thigh bone (femur) that forms the hip joint.
(In the image above, this is depicted as the sky-blue, ball-shaped bone.)
-Avascular Necrosis (AVN): A term that literally means tissue death (necrosis) caused by a lack of blood supply (avascular).
In summary, it is a condition where bone cells die due to insufficient blood flow to the femoral head.
Bone is living tissue that requires a constant supply of oxygen and nutrients via the bloodstream to maintain its function. When this blood supply is interrupted, the bone structure weakens. Eventually, it becomes unable to withstand the body's weight, leading to necrosis and potential collapse.
2. Major Causes of Avascular Necrosis of the Femoral Head
There are 4 primary causes identified for this condition.
1) Excessive Alcohol Consumption
This is the most significant and prevalent cause. It accounts for a high percentage of cases among Korean patients. Alcohol is known to contribute to lipid accumulation within blood vessels and increase blood viscosity, which leads to the occlusion of microvessels.
2) Steroid Use
The risk of developing this condition may increase when steroids are used in high doses or over long periods to treat underlying conditions such as dermatological disorders, kidney diseases, or rheumatoid arthritis.
(Please consult with a medical specialist regarding all medication-related inquiries and dosage instructions.)
3) Trauma
The condition can occur following severe trauma, such as fractures or dislocations around the hip joint, which may damage the blood vessels supplying the bone.
4) Other Factors (Poor Posture)
The fundamental cause of avascular necrosis is the disruption of adequate blood supply.
Maintaining poor posture or squatting for extended periods can significantly increase the likelihood of restricted blood flow to the hip joint.
Therefore, maintaining proper posture and performing regular stretching exercises during work are of utmost importance for prevention.
3. Early Symptoms
One of the most critical characteristics of Avascular Necrosis of the Femoral Head is that it is often asymptomatic in its initial stages. However, as the necrosis progresses, the following symptoms begin to manifest gradually:
ㆍGroin (Inguinal) Pain: This is the most distinct early symptom. Patients typically experience a dull ache in the anterior thigh or groin area, rather than in the posterior buttocks.
ㆍPain during Ambulation: Pain is felt when walking, particularly when weight is applied to the affected leg, often resulting in a limp.
ㆍRestricted Range of Motion: As the necrosis advances and bone collapse begins, actions such as sitting cross-legged or picking up objects from the floor become increasingly difficult.
ㆍNight Pain and Pain at Rest: In advanced stages, throbbing pain may persist even while resting or sleeping at night.
4. Diagnosis and Treatment
If you are experiencing the early symptoms described above and suspect you may be affected, do not hesitate to consult an orthopedic specialist immediately.
ㆍDiagnosis : Since early detection via X-ray can be difficult, Magnetic Resonance Imaging (MRI) is the most accurate diagnostic method if the condition is suspected. MRI can clearly visualize even the initial stages of bone necrosis progression.
ㆍTreatment : Treatment strategies are determined based on a comprehensive evaluation of factors such as the stage of progression, the extent of necrosis, the patient's age, and activity level.
ㆍ Conservative Management (Early Stage) : In very early stages where the necrotic area is small and there is no bone collapse, options such as medication or the use of crutches (to restrict weight-bearing) may be attempted.
However, it is important to note that these methods may have limitations in halting the progression of necrosis.
ㆍ Surgical Treatment
1) Core Decompression
This procedure can be considered in the early stages, prior to bone collapse. It involves drilling into the necrotic bone to reduce internal pressure and stimulate the growth of new blood vessels (neovascularization).
2) Total Hip Arthroplasty (Replacement)
This is the most definitive and widely adopted treatment method when bone collapse has occurred or pain is severe. The procedure involves removing the damaged femoral head and replacing it with an artificial joint composed of specialized alloys and materials.
💪For Your Healthy Hip Joints
Although the name 'Avascular Necrosis of the Femoral Head' may sound unfamiliar, it is not an uncommon condition, particularly among frequent drinkers and workers who perform tasks requiring prolonged squatting.
The most critical preventive measures include avoiding excessive alcohol consumption, maintaining proper posture, and protecting the hip joints from impact.
Above all, if you possess known risk factors (such as alcohol or steroid use) and experience
unexplained groin pain persisting for more than two weeks, do not neglect it. We strongly advise you to visit a medical facility immediately for an accurate diagnosis.
Early detection is the most effective way to preserve the health of your hip joints.
Protecting your hip joints is the best preventive measure
for a healthy and active old age.
