Introduction
Due to the importance of scaphoid in wrist mechanics
Typically, the injury affects young active
males and results from a fall on the
outstretched hand.
Uncommon in children because the physis of distal radius fails first
Second to the distal radius in frequency
Missed diagnosis of an acute scaphoid
fracture exposes the patient to the risk of
nonunion and malunion and their
attendant sequelae, including scapholunate
advanced collapse of the wrist.

OTHER COMPLICATIONS:
• Osteosynthesis intolerance (23%)  EMOS
• Schaphoid colapse (2,3%)
• Intracarpus artrosis (13,9%)
Left hand
Conclusions
• 86% consolidation rate
• Good results in 87,5% of the pacients
• Osteosynthesis is not good for Alnot IV (AVN)
• We can’t say we stop the Natural History of the
disease
• Recent studies indicated that virtually all unstable
nonunions lead to carpal collapse and posttraumatic
arthritis,, for this reason treatment is recommended
for all scaphoid nonunions even if asymptomatic
