Fracture and ischemic necrosis of the immature scaphoid.
The progressively ossifying scaphoid of the child is well protected but is not immune to injury. The diagnosis of scaphoid fracture may be difficult when the fracture occurs through the osteochondral interface. Nonunion and ischemic necrosis of the proximal pole fragment--complications more often seen in adults sustaining scaphoid fracture--may occur in children, as shown by the young patient presented here.
