• ✓Confirmation of idiopathic etiology with no underlying cause identified
• ✓Imaging evidence showing bone necrosis in right hand metacarpal structures
• ✓Clear laterality documentation specifying right hand involvement
• ✓Exclusion of infectious processes through clinical evaluation
• ✓Assessment of hand function, grip strength, and fine motor skills
• ✓Treatment plan including conservative management or surgical options
