M87.02
Idiopathic aseptic necrosis of humerus
Clinical Classification Guidelines
Medical Intelligence & Overview
Idiopathic aseptic necrosis of the humerus, also known as osteonecrosis of the humeral head, is a condition characterized by the death of bone tissue in the upper arm bone's head without infection or a clear traumatic cause. This condition can lead to joint pain, reduced mobility, and eventually arthritis if left untreated. It predominantly affects adults and may develop gradually over time, often without obvious symptoms in the early stages.
Causes & Symptoms
Clinical Causes: Long-term use of high-dose corticosteroids Excessive alcohol consumption Decompression sickness, commonly seen in divers Blood disorders, such as sickle cell anemia or hemoglobinopathies Trauma or injury to the shoulder, although this is less common in idiopathic cases Certain medical treatments or conditions that impair blood supply to the humeral head
Key Symptoms: Gradual onset of shoulder pain, especially with movement or bearing weight Limited range of motion in the shoulder joint A feeling of stiffness or weakness in the affected arm Pain that worsens with activity and may persist at rest in later stages Possible swelling or tenderness around the shoulder Crepitus or grinding sensation during shoulder movement in advanced cases
Diagnostic & Treatment
Diagnosis Path: Physical examination to evaluate shoulder mobility, tenderness, and strength X-rays to visualize changes in the bone, such as subchondral fractures or collapse Magnetic resonance imaging (MRI) for early detection of bone death before significant structural damage occurs Bone scans or other nuclear imaging techniques to assess blood flow and bone vitality
Treatment Protocols: Conservative therapies such as rest, activity modification, and non-steroidal anti-inflammatory drugs (NSAIDs) to alleviate pain Physical therapy to maintain joint mobility and strengthen surrounding muscles Core decompression surgery to reduce intraosseous pressure and promote blood flow Osteotomy, a surgical procedure to realign or redistribute weight in the shoulder Joint-preserving surgeries or bone grafting in early stages of the disease Joint replacement (humeral head arthroplasty) in advanced cases where the joint is severely damaged
