- ✓Documentation of causes other than idiopathic or drug-induced osteonecrosis
- ✓Imaging confirmation (MRI, X-ray) showing bone necrosis in right finger(s)
- ✓Clinical symptoms including finger pain, stiffness, swelling, or deformity
- ✓Exclusion of infectious or traumatic causes as primary etiology
- ✓Assessment of impact on fine motor function and hand dexterity
- ✓Documentation of which specific fingers are affected if known
