FARIVAR A LAHIJI M.D

Epidemiology • The most frequent fractured bone of the wrist• 10-15% of hand and wrist fractures• 60-80% of carpal fractures• Waist 65%• 1/3 distal 10%• 1/3 proximal 15%

FARIVAR A LAHIJI M.D

Mechanism• Axial load over

hyperextended and radially deviated wrist

FARIVAR A LAHIJI M.D

Anatomy • 75-80% covered by

articular cartilage

FARIVAR A LAHIJI M.D

Blood supply• major blood supply is 

dorsal carpal branch (branch of the radial artery) supplies proximal 80% of

scaphoid via retrograde blood flow• minor blood supply from 

superficial palmar arch (branch of volar radial artery) supplies distal 20% of

scaphoid

Cast treatment has the disadvantages of longer immobilisation time, joint stiffness, reduced grip strength, and longer time to return to manual work. Percutaneous fixation is aimed at reducing damage to the blood supply and soft tissues, allowing early mobilisation of the wrist and early return to manual work. The best available evidence for percutaneous screw fixation versus cast treatment suggests that percutaneous fixation allows a faster time to union by 5 weeks and an earlier return to manual work by 7 weeks, with similar union rates.

Percutaneous fixation is a valuable treatment method for Type B scaphoid fractures as it enables early wrist motion and high patient satisfaction.
