About osteonecrosis.
Osteonecrosis, is the necrosis of living tissue components of the human skeleton. There are many parts of the body that can cause osteonecrosis. Osteonecrosis of the femoral head is often the most common and most prevalent clinical condition.
The treatment effect of osteonecrosis of the femoral head has a great relationship with the severity of the disease, the early and late detection, and the stage of the disease, the earlier the lesion is found, the lighter the disease, the better the treatment effect.
Femoral head necrosis is a pathological evolutionary process that initially occurs in the weight-bearing area of the femoral head. Its early manifestation is misdiagnosed as pain in the knee joint and inner thigh, which manifests as constant pain and resting pain, and many people do not put this on their mind and miss the treatment time.
How to self-diagnose?
(1) Any adult between 20 and 50 years old with pain in the groin or hip and dispersion to the thigh (or hip pain after activity on one side of the knee pain), slowly progressive aggravation, obvious pain at night, ineffective by general medication, and a history of trauma or alcoholism or application of hormones or other causative factors and diseases causing femoral head necrosis should first consider this disease.
(2) All patients with low back pain should be routinely checked for hip function during physical examination. If abduction and internal rotation of the affected hip joint are found to be limited, the presence of femoral head necrosis should be suspected. 
How is it treated?
For muscle pain, the analgesic effect of shock wave therapy equipment is more obvious than other physical therapy equipment. It is a non-invasive treatment, which is less harmful to patients, and through the positioning and movement of the treatment head, it can produce the effect of loosening adhesions and unblocking the tissues of the body where the pain occurs more extensively.
In addition, it is important to note that some patients experience a reduction or disappearance of hip pain after a period of treatment, however, it does not mean that the condition is cured. The real diagnosis is assessed by imaging such as X-rays and ECT. Through these assessments, changes within the femoral head can be seen, from ischemic to stasis type, from reconstruction of bone trabeculae to shaping, and only after the cystic area within the femoral head is seen to disappear and be filled with new bone, the bone trabeculae are arranged in an orderly manner, and the femoral head reaches a certain level of support is considered healed.
During the treatment period, use double crutches for standing, reduce weight bearing, don’t drink alcohol, stay away from cold and damp, keep moderate exercise and massage, and finally, encourage the patient to build up confidence in recovery!
