Volar Approach for Scaphoid Fractures Nader Paksima, DO, MPH

Clinical Professor of Orthopaedic Surgery 

NYU/Hospital for Joint Diseases

• Internal Fixation indicated for displacement >1mm

• Percutaneous fixation recommended only for non‐displaced or minimally displaced fractures

• Union rates and complication rates similar for open and percutaneous screw fixation• (94‐100%, 0‐30%)

• 16 Dorsal

• 10 Volar 

• No difference in healing rates. 80 versus 81%

Why go volar? 7 reasons :

• Maintain vascularity

• Correct the humpback / Easy reduction

• Avoid articular injury

• Can do percutaneously

• The more distal the better ( ship to shore, screw perpendicular)

• Versatility : • Easy to add bone graft / nascent nonunion

• Have bailouts: k wires, plate, carpentry

Why not go Volar?

• Screw Trajectory less than Ideal
