Detection and Staging of Idiopathic Osteonecrosis of the Scaphoid (Preiser’s Disease)

Osteonecrosis

“…Examination shows decreased range of motion, wrist swelling, and decreased grip strength 21 . MRI findings include a proximal necrotic zone, a middle repair zone, and a distal zone of maintained bone viability 22 . Treatment for scaphoid osteonecrosis has not been completely determined The navicular bone is highly vascularized with multiple penetrating vessels, but unfortunately these vessels do not fully reach the middle third of the bone, and this area is prone to both fractures and osteonecrosis 23 .…”

Treatment for scaphoid osteonecrosis has not been completely determined because the condition is rare, but conservative measures alone appear to be beneficial for most 20 .…”
