Unlike post-traumatic scaphoid osteonecrosis, Preiser disease occurs in the absence of preceding fracture or trauma , posing diagnostic challenges for clinicians and radiologists alike. The scaphoid bone plays a central biomechanical role in wrist stability , bridging the proximal and distal carpal rows. Compromise of its vascular supply—especially in the proximal pole—can lead to progressive collapse, degenerative arthritis, chronic pain, and significant functional disability .
