Diagnosis Path: Diagnosis typically involves a combination of medical history review, physical examination, and imaging studies: - Medical history assessment to identify risk factors - Physical exams focusing on joint tenderness, range of motion, and stability - Imaging techniques such as X-rays, MRI, or CT scans - X-rays may reveal areas of bone collapse or deformity in later stages - MRI is more sensitive in early detection, showing bone marrow changes - Sometimes, blood tests are performed to rule out other conditions Early detection is crucial to prevent joint destruction and plan effective management strategies.

Treatment Protocols: Treatment options aim to alleviate pain, halt disease progression, and restore function. They include: - Conservative management: - Rest and activity modification - Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief - Physical therapy to strengthen muscles and improve joint function - Assistive devices, such as crutches or canes, to reduce weight load - Surgical interventions: - Core decompression to relieve pressure within the bone - Bone grafts or joint substitutes in more advanced cases - Hip replacement surgery if significant joint damage has occurred Early and appropriate treatment can enhance joint preservation and improve quality of life. Continuous follow-up is essential to monitor disease progression and response to therapy.
