AVN (Avascular Necrosis) is a medical condition in which bone tissue dies due to a lack of blood supply. If it goes untreated, the bone can become weak and brittle, leading to a collapse of the affected joint (most often the hip or shoulder). This can cause a great deal of pain and can limit the mobility of the joint, leading to decreased quality of life.
Signs and Symptoms
Some of the common signs and symptoms of AVN include pain, swelling, stiffness, and difficulty moving the affected joint. The pain may worsen over time and can become severe. In some cases, the joint may appear to be deformed and there may be a grating sensation when moving it.
Diagnosis
AVN is usually diagnosed with an X-ray or MRI scan. The scan will show any areas of bone death or collapse. Your doctor may also order blood tests to rule out other conditions that can cause similar symptoms.
Treatment
Treatment for AVN may include medications to reduce pain and inflammation, physical therapy to help maintain joint mobility and strength, and possibly surgery to replace the affected joint. Early diagnosis and treatment are important to prevent further damage and to help improve quality of life.
Complications
If AVN is not treated, it can lead to complications such as joint instability, arthritis, and chronic pain. In some cases, the joint may need to be replaced if it is too damaged to be repaired.
By getting an early diagnosis and prompt treatment, AVN can be managed and its progression slowed. Talk to your doctor if you are experiencing any pain or stiffness in your joints.
