Avascular Necrosis

Unraveling Bone Health Challenges

Avascular necrosis, known as osteonecrosis, occurs when bone tissue dies due to insufficient blood supply, often stemming from fractures or joint dislocations. While commonly affecting the hip joint, it can also impact the knee and shoulder.

Exploring Risk Factors

Chronic steroid use and excessive alcohol consumption are primary risk factors for avascular necrosis. These factors contribute to bone damage, leading to potential collapse and loss of function.

Identifying Symptoms

Symptoms may manifest suddenly after injury or gradually over time, presenting as pain and stiffness in the affected joint. Diagnostic imaging, including X-rays, MRI scans, and bone scans, aid in accurate diagnosis and rule out alternative causes of joint discomfort.

Tailored Treatment Approaches

Treatment goals focus on halting further bone deterioration and vary based on disease progression. Conservative measures, such as NSAIDs for pain management and rest to reduce weight-bearing, may suffice in early stages. For advanced cases, surgical interventions become necessary.

Conservative Management Strategies

Non-surgical approaches encompass medication to alleviate pain, restricted activity to minimize stress on the affected joint, targeted exercises to improve mobility, and electrical stimulation to foster bone regeneration.

Surgical Interventions

Advanced avascular necrosis may require surgical intervention. Core decompression alleviates pressure within the bone, stimulating new blood vessel growth and bone regeneration. Bone transplant involves grafting healthy bone from elsewhere in the body, while bone reshaping redistributes stress on affected bones. In severe cases, joint replacement surgery becomes an option to restore function and mobility.

Comprehensive Care for Bone Health

At Michigan Joint Replacement Institute (MJRI), we prioritize patient-centered care and employ a multidisciplinary approach to address avascular necrosis. From accurate diagnosis to personalized treatment plans, we strive for excellence in bone health restoration, empowering patients to reclaim their quality of life.
